Redefining Biodiversity for 2025: What It Means and Why It Matters 🌿

The concept of biodiversity has evolved significantly since our original article was published. Based on extensive research, it's clear that understanding biodiversity is more crucial than ever—not just as an abstract scientific concept, but as the foundation of human existence, economic prosperity, and planetary health.

What Is Biodiversity in Today's Context?

Biodiversity still fundamentally refers to the variety of life on Earth, but our understanding has deepened considerably. Modern science now recognizes biodiversity across multiple dimensions:

• Species diversity: Beyond just counting species, we now understand complex relationships between organisms, with recent discoveries continuing to expand our knowledge (over 100 new species discovered from a single seamount off Chile's coast in 2024 alone!)
• Genetic diversity: The genetic variation within species that enables adaptation to changing conditions—a critical component increasingly protected through initiatives like the Svalbard Global Seed Vault and Kew's Millennium Seed Bank
• Ecosystem diversity: The variety of habitats and ecological processes that support life, including newly recognized "unseen worlds" like soil microbiomes that contain over half the planet's biodiversity
• Functional diversity: How different species contribute to ecosystem processes and services—moving beyond simply counting species to understanding their ecological roles

Why Biodiversity Matters More Than Ever

The value of biodiversity has taken on new urgency as research reveals:

• An estimated $58 trillion of global GDP (55%) is moderately or highly dependent on nature
• The total value of ecosystem services exceeds $182 trillion annually
• Current biodiversity loss threatens economic stability, with potential GDP losses of up to 10% annually by 2030 for low-income countries

Most importantly, biodiversity isn't just about preserving nature in isolation—it's now recognized as fundamentally interconnected with climate resilience, food security, disease prevention, and sustainable development.

Our updated article will explore these connections in depth, along with cutting-edge measurement techniques, major conservation initiatives, and practical actions everyone can take to support biodiversity in their daily lives—from conscious consumption choices to creating wildlife-friendly spaces and participating in citizen science.

This comprehensive update transforms our original explanatory piece into an actionable resource that reflects the latest scientific understanding while empowering readers to participate in creating a nature-positive future.

Comprehensive Biodiversity Update: Scientific Advancements, Conservation Progress & Action Framework

I. The Current State of Global Biodiversity: A Quantitative Overview

The biosphere, the intricate web of life that sustains human civilization, is facing unprecedented challenges. Decades of scientific assessment have documented accelerating biodiversity loss, driven by human activities that alter landscapes, modify climate systems, introduce invasive species, and pollute ecosystems. Understanding the current state of global biodiversity requires examining key quantitative indicators, identifying regions undergoing rapid transformation, tracking species discoveries and status changes, and appreciating the profound economic implications of nature's decline.

A. The Scale of the Crisis: Key Indicators

Multiple lines of evidence from leading global authorities paint a stark picture of biodiversity decline. The International Union for Conservation of Nature (IUCN), the global authority on the status of the natural world, provides critical data through its Red List of Threatened Species™. As of early 2025, over 169,400 species have been assessed, with more than 47,000 (approximately 28% of those assessed) classified as threatened with extinction.¹ This threat level varies significantly across major taxonomic groups, indicating broad systemic pressure (See Table 1).

Beyond species-level threats, population abundances are plummeting. The World Wildlife Fund's (WWF) Living Planet Index (LPI), which tracks trends in monitored vertebrate populations, revealed a staggering average decline of 73% between 1970 and 2020.³ This dramatic reduction signifies not only the loss of individuals but also a critical erosion of genetic diversity within species, weakening their resilience to environmental changes like climate change and disease.⁴

The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), in its landmark 2019 Global Assessment Report, estimated that around 1 million animal and plant species are threatened with extinction, many within decades.⁵ This assessment also highlighted the profound alteration of ecosystems, finding that human actions have significantly altered three-quarters of the land-based environment and about two-thirds of the marine environment.⁵ More recent IPBES work, such as the 2024 Nexus Assessment, indicates a continued decline across assessed biodiversity indicators, averaging 2-6% per decade over the last 30-50 years.⁶ This persistent degradation underscores the urgency of addressing the underlying drivers of loss.

B. Hotspots Under Pressure: Regions of Rapid Change

Biodiversity is not evenly distributed across the planet. Certain regions, known as biodiversity hotspots, harbor exceptionally high concentrations of endemic species (those found nowhere else) yet face extreme threats from human activities.¹⁰ Defined by Conservation International as areas with at least 1,500 endemic vascular plant species and having lost 70% or more of their original natural vegetation, these 36 hotspots cover just 2.5% of Earth's land surface but support over half the world's endemic plant species and nearly 43% of endemic bird, mammal, reptile, and amphibian species. They also provide an estimated 35% of vital ecosystem services for vulnerable human populations, making their conservation critical for both nature and people.¹⁰ Several hotspots are currently experiencing particularly rapid and concerning changes:

• The Amazon: The world's largest rainforest faces complex pressures. While Brazil reported a significant 30.6% decrease in deforestation for the year ending July 31, 2024 (reaching the lowest level since 2015), this positive trend was counteracted by a devastating surge in wildfires later in the year.¹¹ Driven by historic drought conditions exacerbated by climate change, fires in September 2024 increased nearly 18-fold compared to the previous year.¹¹ Ongoing threats from agricultural expansion, infrastructure development (such as the controversial BR-319 highway), and the cumulative impacts of climate change and degradation risk destabilizing the entire ecosystem, potentially disrupting continental rainfall patterns and accelerating biodiversity loss.¹¹ Notably, Indigenous territories within the Amazon consistently demonstrate lower rates of deforestation compared to surrounding areas, highlighting the effectiveness of Indigenous stewardship.¹³
• The Great Barrier Reef (GBR): The GBR experienced a catastrophic coral bleaching event in early 2024, driven by unprecedented marine heatwaves.¹⁴ Significantly, this event severely impacted the southern GBR, an area previously considered relatively resilient.¹⁴ A peer-reviewed study documented that 66% of monitored coral colonies at One Tree Island were bleached by February 2024, rising to 80% by April. By July 2024, 44% of these bleached colonies had died, with mortality rates reaching a staggering 95% for sensitive genera like Acropora.¹⁴ The rapid onset of bleaching and associated diseases like black band disease underscores the reef's vulnerability to accelerating climate change.¹⁴
• The Pantanal: The world's largest tropical wetland, spanning Brazil, Bolivia, and Paraguay, suffered devastating wildfires in 2024.¹⁶ By August 2024, fires had consumed 1.22 million hectares ¹⁶, with other estimates suggesting over 1.3 million hectares burned in total, including 440,000 hectares in June alone.¹⁷ These fires, fueled by a combination of climate change-induced drought and human activities (like land clearing for agriculture), have had unimaginable impacts on the region's unique flora and fauna. The severe fires of 2020 were estimated to have killed or displaced 45% of the Pantanal's jaguar population, formerly the second-largest in the world.¹⁶ The ongoing destruction threatens not only biodiversity but also the livelihoods and water security of local communities.¹⁶
• The Cerrado: Brazil's vast tropical savanna, another biodiversity hotspot heavily impacted by agricultural expansion (soy, cattle), saw a 25.7% decrease in deforestation in the year ending July 2024, the first decline in five years. However, like the Amazon and Pantanal, it experienced severe fire damage, which is often not captured in deforestation statistics but represents significant ecosystem degradation.¹¹
• Other Regions: Rapid negative changes are occurring elsewhere. On Socotra Island (Yemen), several endemic frankincense tree species were recently uplisted to Endangered or Critically Endangered due to pressures from overgrazing, prolonged droughts, and increasingly frequent extreme weather events like cyclones.⁹ Within the United States, assessments reveal high levels of threat for endemic freshwater fish (139 threatened, 14 extinct/EW out of 582), birds (nearly all 77 endemic species threatened or extinct/EW), trees (over half of 519 endemic species threatened), and freshwater crayfish (56 threatened, 2 extinct/EW out of 343).²

A critical pattern emerging across these diverse hotspots is the role of climate change as a potent threat multiplier. While direct drivers like land-use change (agriculture in the Amazon, Pantanal, Cerrado) and overexploitation (grazing in Socotra) remain significant, recent extreme events underscore how climate change intensifies these pressures. Unprecedented marine heatwaves triggered the GBR bleaching ¹⁴; historic droughts fueled catastrophic fires in the Amazon and Pantanal ¹¹; and drought combined with cyclones exacerbated threats to Socotra's unique flora.⁹ This aligns with broader scientific consensus from bodies like IPBES and the IPCC, which identify climate change as a primary and accelerating driver of biodiversity loss.⁶ It suggests that even relatively intact or previously resilient ecosystems are being pushed towards potential ecological tipping points – thresholds beyond which abrupt and potentially irreversible changes occur.³

C. The Expanding Tree of Life (and Loss): New Discoveries & Notable Status Changes

Despite the accelerating loss of biodiversity, scientific exploration continues to reveal the planet's hidden diversity. In 2024 alone, numerous new species were described, including potentially over 100 from an unexplored seamount off Chile's coast (including deep-sea corals, sponges, and urchins), a new giant anaconda species from the Ecuadorian Amazon, distinctive creatures from the Greater Mekong region like the "vampire hedgehog" (Hylomys macarong) and an "eyelash" pit viper (Trimeresurus ciliaris), three species of tree-dwelling pandan frogs from Madagascar, two new species of rare toothed toads from Vietnam and China, the world's smallest otter species from India, and a new tiger beetle (Eunota houstoniana) from the Texas Gulf Coast.²⁰ Expeditions continue to yield discoveries, such as the 27 new-to-science species (including four mammals) found during a two-month expedition in Peru's Alto Mayo Landscape.²⁰

These discoveries often highlight the invaluable role of Indigenous Peoples and local communities (IPLCs), whose traditional ecological knowledge frequently precedes formal scientific documentation by generations. Examples include the blob-headed fish known to the Awajún people in Peru, the ghost palm used by Iban communities in Borneo, and the pandan frogs familiar to local communities in Madagascar.²⁰ However, the excitement of discovery is often tempered by immediate conservation concerns. Many newly described species are found in highly threatened habitats or possess characteristics that make them vulnerable, leading to immediate assessment as threatened or endangered.²⁰ The Houston tiger beetle, for instance, inhabits saline soils near oil extraction sites, and its habitat is increasingly jeopardized by urbanization and industrial activity, making it likely already threatened despite being newly discovered.²¹

Concurrent with new discoveries, the conservation status of known species continues to fluctuate, tracked meticulously by the IUCN Red List. Recent updates show both alarming declines and hopeful recoveries:

• Declines: Beyond the concerning trends for fungi and Socotran frankincense trees detailed previously ⁹, the Atlantic salmon (Salmo salar) was assessed as Near Threatened globally, reflecting a 23% population decrease between 2006 and 2020, linked partly to climate change impacts across its lifecycle (though farmed populations remain stable).²²
• Improvements: Conservation interventions have led to genuine recoveries. The Saiga Antelope (Saiga tatarica), once Critically Endangered due to poaching and disease, was downlisted to Near Threatened following significant population recovery driven by government and community conservation efforts in Central Asia.²² Similarly, the Scimitar-horned Oryx (Oryx dammah), previously Extinct in the Wild, was successfully reintroduced in Chad and downlisted to Endangered.²² Several Asian stork species were also reclassified to lower threat categories due to community-based conservation actions.²²
• Clarified Status: The first IUCN Green Status of Species assessment for the Lion (Panthera leo) provides a nuanced picture. While the species remains classified as Vulnerable on the Red List, the Green Status assessment indicates it is "Largely Depleted" from an ecological perspective across its historical range due to human impacts. This highlights that while conservation efforts have successfully prevented likely extinctions in parts of Africa and India, the species is far from achieving ecological recovery across its full range.⁹

These status changes illustrate that dedicated conservation action can achieve measurable success in recovering threatened populations. The improvements for the Saiga Antelope and Scimitar-horned Oryx are directly attributed to targeted interventions like anti-poaching enforcement, habitat management, reintroduction programs, and crucially, the involvement of governments and local communities.²² However, these successes often stand in contrast to broader declines driven by systemic pressures like climate change (affecting Atlantic Salmon ²²) or pervasive human impacts (affecting Lion recovery ⁹). This suggests that while specific, targeted conservation actions are vital and effective, they must be complemented by broader efforts addressing the root causes of biodiversity loss, as emphasized in IPBES assessments calling for transformative change.²³ Sustained investment and tackling systemic drivers are necessary to shift the overall trajectory from loss towards recovery.

D. Valuing Nature: The Economic Imperative

Demonstrating the economic value of biodiversity and the ecosystem services it provides is increasingly recognized as crucial for integrating nature into economic decision-making and motivating conservation action.²⁵ Stable, functioning natural ecosystems fundamentally underpin all economic activity, providing essential resources, regulating climate and water cycles, mitigating disasters, and supporting livelihoods.¹⁹

Recent assessments attempt to quantify this dependence and value:

• GDP Dependence: An estimated $58 trillion of global GDP – equivalent to 55% – is moderately or highly dependent on nature, according to 2023 PwC analysis cited in the Biodiversity Finance Factbook. This figure is significantly higher than previous estimates, suggesting a growing recognition of economic reliance on natural capital.²⁶
• Ecosystem Service Value: The total global value of ecosystem services provided by nature is estimated to be in excess of $182 trillion annually, a value captured in metrics like Gross Ecosystem Product (GEP).²⁶
• Unaccounted Costs: Current economic models often fail to account for the negative impacts of economic activity on nature. IPBES estimates these unaccounted-for costs range from USD $10 trillion to $25 trillion per year.²⁷
• Sectoral Dependence: Specific sectors show high dependence. Globally, the fisheries sector directly employs 60 million people, with the total value chain supporting around 200 million jobs, 60% of which are in the developing world.²⁵

Conversely, the economic risks associated with biodiversity loss are substantial and growing:

• GDP Losses: World Bank modeling indicates that the collapse of just a few key ecosystem services could cause low-income countries to lose 10% of their real GDP annually by 2030, compared to 2.3% globally. Sub-Saharan Africa (potential 9.7% annual loss) and South Asia (potential 6.5% annual loss) are particularly vulnerable.²⁵
• Global Risk Perception: The World Economic Forum's 2024 Global Risks Perception Survey ranked "Biodiversity loss and ecosystem collapse" as the third most severe global risk over the next decade.²⁶
• Financial System Risks: Nature loss is increasingly recognized as a source of financial risk, stemming from both the physical impacts of ecosystem service decline and transition risks associated with policy changes or shifts in market preferences that devalue assets linked to nature degradation.²⁹

Despite the clear economic rationale for conservation, financial flows remain severely inadequate and misaligned. The gap between current biodiversity finance and estimated needs is vast and widening:

• Current Funding: Global biodiversity finance flows amount to approximately $208 billion per year.²⁶
• Estimated Need: Achieving global goals, including the Kunming-Montreal Global Biodiversity Framework (GBF) target of mobilizing $200 billion per year by 2030 and eliminating $500 billion per year in harmful subsidies ³¹, requires an estimated $1.15 trillion per year by 2030.²⁶ Other estimates place the required funding between $300 billion and $1 trillion annually.⁶
• Finance Gap: The shortfall between current flows and the $1.15 trillion estimated need has widened to approximately $942 billion per year.²⁶
• Harmful Subsidies: Subsidies detrimental to biodiversity (e.g., for fossil fuels, intensive agriculture) are estimated at $1.4 trillion to $3.3 trillion per year ²⁸, or around $1.7 trillion per year.²⁷ This means the world spends vastly more (potentially 35 times more ⁶) on activities that harm nature than on protecting it.
• Cost of Inaction: Delaying action significantly increases costs. Postponing biodiversity conservation efforts could double the eventual financial burden.²⁷

Table 2: Economic Value & Finance Gap (Annual Estimates)

The strengthening economic case for biodiversity conservation, evident in improved valuation methodologies like Gross Ecosystem Product ²⁶ and assessments of GDP dependence ²⁶, starkly contrasts with the reality of financial flows. The immense finance gap ²⁶ and the overwhelming scale of harmful subsidies ²⁷ demonstrate a fundamental failure within current economic and financial systems to align investments with the recognized value of natural capital. This disconnect underscores why international bodies like IPBES call for transformative changes in economic paradigms, financial mechanisms, and governance structures to shift incentives and redirect capital towards nature-positive outcomes.²⁸ Simply quantifying nature's value has proven insufficient; systemic reform is required to translate that value into tangible financial commitment and action.

II. Frontiers in Biodiversity Science: New Ways of Seeing and Understanding

Responding effectively to the biodiversity crisis requires not only quantifying the loss but also developing more sophisticated ways to measure, monitor, and understand the complexities of life on Earth. Scientific advancements are providing powerful new tools and conceptual frameworks, from analyzing trace amounts of DNA in the environment to understanding the critical roles of microorganisms and the dynamics of ecological resilience.

A. Beyond Counting Species: Innovative Measurement & Monitoring

Traditional biodiversity assessments often rely on species counts and direct observation, which can be resource-intensive, logistically challenging, and insufficient for capturing the full picture, especially for elusive species or complex ecosystem functions. The need for more comprehensive, scalable, and standardized measurement approaches is driven by demands from international policy (e.g., monitoring progress towards GBF targets) and the private sector (e.g., corporate biodiversity disclosure).³⁴ Several innovative methodologies are transforming the field:

• Environmental DNA (eDNA): This rapidly growing field analyzes DNA shed by organisms into their environment (water, soil, air, snow, surfaces).³⁶ eDNA techniques are highly sensitive and time-efficient, allowing for the detection of species presence without direct observation.³⁶ Applications include monitoring aquatic ecosystems ³⁶ and, increasingly, terrestrial environments.³⁷ It has proven particularly effective for detecting rare, elusive, or cryptic species, such as the endangered yellow mud turtle in Texas oxbow lakes ³⁸, forest mammals and bats identified through tree bark swabs ³⁹, and skinks under cover boards.³⁹ It is also used for early detection of invasive species like the spotted lanternfly, proving more effective than visual surveys in some cases.³⁹ Metabarcoding techniques applied to eDNA samples allow for the assessment of entire communities across the tree of life.³⁷ However, limitations exist: terrestrial applications are less mature than aquatic ones, the choice of sampling substrate significantly impacts results, performance compared to traditional methods can vary depending on context, and potential biases in amplification or reference databases need consideration.³⁷
• Remote Sensing (RS): Technologies like satellite imagery, Light Detection and Ranging (LiDAR), and sensors mounted on Unmanned Aerial Vehicles (UAVs or drones) provide critical tools for large-scale, non-intrusive biodiversity monitoring.⁴⁰ RS is widely used to map vegetation cover, detect habitat fragmentation, model species distributions, monitor ecosystem dynamics, and assess the impacts of urban sprawl.⁴¹ It is also valuable for monitoring the progress of habitat restoration efforts, such as tracking vegetation recovery ⁴² or assessing restored shoreline and wetland habitats in the Great Lakes.⁴³ Despite its power, RS applications face challenges, including a geographical bias towards the Global North and large metropolitan areas, limited focus on certain biomes (boreal, desert, tropical), practical and regulatory hurdles for widespread UAV deployment (especially over cities), and issues with spectral confusion between different urban materials.⁴¹ Integrating data from multiple RS platforms also remains complex.⁴¹
• Artificial Intelligence (AI)-Assisted Identification & Monitoring: AI and machine learning offer transformative potential for analyzing the vast and complex datasets generated by modern biodiversity monitoring.⁴⁴ AI algorithms can rapidly process images, acoustic recordings, and genetic sequences to automate species identification (e.g., McGill University's BioCLIP tool, automated insect monitoring platforms like Antenna ⁴⁵), map species distributions more accurately using satellite and eDNA data ⁴⁵, and potentially infer complex species interactions like food webs.⁴⁵ Practical applications include analyzing drone imagery to monitor koala populations ⁴⁶ and providing real-time alerts for anti-poaching efforts using AI-powered camera traps (Resolve's TrailGuard AI ⁴⁶) or smart collars on rhinos that detect abnormal behavior.⁴⁷ Researchers are exploring how AI can help address long-standing biodiversity knowledge gaps, such as the Linnaean shortfall (cataloging species) and the Wallacean shortfall (mapping distributions).⁴⁴ However, realizing AI's full potential requires addressing challenges related to data sharing for model training, reducing algorithmic bias, and ensuring ethical application in conservation contexts.⁴⁵
• 'Units of Nature' and Biodiversity Credits: Driven by the need for businesses and financial institutions to measure, disclose, and invest in nature, there is a growing effort to develop standardized, generalizable "units of nature" for use in voluntary biodiversity credit markets.³⁴ These methodologies attempt to quantify biodiversity gains (restoration) or avoided losses (conservation) in a tradable format, often based on area (per hectare) and sometimes using composite indicators derived from a "basket of metrics" (e.g., population, species, ecosystem data) or simpler binary conditions (e.g., presence of indicator species, absence of deforestation).³⁴ However, this push for standardization faces profound conceptual and practical challenges. Defining a single unit that captures the multifaceted, place-based value of biodiversity is inherently difficult, raising issues of fungibility (can a unit of restored wetland truly offset the loss of primary forest?).³⁴ Quantifying biodiversity involves subjective choices about which metrics to include and how to weight and aggregate them, potentially masking value judgments and failing to represent overall ecosystem health.³⁴ Detecting genuine change attributable to an investment (additionality) is complex, as is accounting for leakage (displacement of threats) and ensuring the permanence of outcomes.³⁴

The rapid advancement of monitoring technologies like eDNA, remote sensing, and AI provides unprecedented power to observe and analyze biodiversity across scales. This technological capacity allows for more efficient detection, broader monitoring coverage, and deeper analytical insights than ever before. However, the concurrent push to translate this complex ecological information into simplified, standardized, and marketable "units of nature" for biodiversity credits introduces significant risks and uncertainties.³⁴ There is a fundamental tension between the financial market's demand for fungible, easily tradable units and the inherent complexity, context-dependency, and multi-dimensional value of biodiversity. While standardization may facilitate investment, it risks oversimplification, potentially leading to perverse outcomes if not implemented with extreme caution, rigorous scientific underpinning, and strict regulations that prioritize genuine ecological benefit over market convenience. Using such credits to quantify positive contributions towards nature recovery, rather than as direct offsets for ongoing damage, may represent a more ecologically sound approach.³⁴

B. Unseen Worlds: Microbiome's Role in Biodiversity

Biodiversity extends far beyond the visible world of plants and animals. Microbial communities – encompassing bacteria, archaea, fungi, viruses, and protists – represent a vast and functionally critical component of life on Earth, yet they have historically been overlooked in many conservation frameworks.⁴⁸ Soil microbiota alone are estimated to comprise over half of the planet's biodiversity and are indispensable for fundamental ecosystem processes, including nutrient cycling (like nitrogen fixation), organic matter decomposition, carbon storage, soil formation, and maintaining plant health.⁵⁰

Advances in molecular techniques, particularly metagenomics (the study of genetic material recovered directly from environmental samples), are revolutionizing our understanding of these microbial worlds.⁴⁸ This allows scientists not only to characterize the taxonomic diversity of microbial communities but also to analyze their collective genetic information to understand their functional potential and interactions within ecosystems.⁴⁸

Research is revealing fascinating ecological dynamics within microbial communities. Studies across diverse ecosystems – from the human gut microbiome to plant rhizospheres, fish populations, and fungal communities – consistently observe a pattern of "hyperdominance," where a small fraction of species accounts for the vast majority of the biomass or abundance.⁵² This contrasts with the traditional view that most species in diverse ecosystems are rare. Further investigation suggests that rarity itself might be a persistent state, a phenomenon termed "stickiness of rarity," potentially arising from stochastic processes where environmental fluctuations affect species proportionally to their abundance.⁵² However, this research also supports the "insurance hypothesis" of biodiversity: these numerous rare microbial species may persist as a reservoir of functional diversity, capable of replacing dominant species that collapse due to environmental change or other pressures, thereby stabilizing overall ecosystem functioning.⁵²

Understanding the microbiome has profound implications for biodiversity conservation and ecosystem management. Anthropogenic pressures, particularly land-use intensification and climate change, are known to negatively impact the diversity, composition, and activity of soil microbial communities.⁵⁰ For example, studies show that high-intensity land use (like conventional cropland compared to extensive grassland) significantly reduces soil microbial respiration and diminishes the community's ability to respond to additional stresses like heatwaves.⁵⁰ This degradation of microbial function threatens the critical ecosystem services they provide.⁵⁰ Consequently, there is a growing call to explicitly integrate soil microbiota into ecological restoration efforts. This involves considering microbial communities during restoration planning, potentially using targeted or broad-spectrum soil inoculations as an intervention strategy, and monitoring microbial diversity and function to assess restoration success.⁵¹ Similar potential exists in agriculture, where manipulating plant microbiomes through inoculation or management practices could enhance crop resilience and sustainability.⁴⁹ Research is also expanding into animal microbiomes, although comparative studies highlight the need to look beyond mammals to develop truly generalized principles of host-microbiome interactions across the animal kingdom.⁵³

The burgeoning field of microbiome research fundamentally reshapes our understanding of biodiversity itself. Recognizing the immense diversity and critical functional roles played by microorganisms – driving biogeochemical cycles, contributing to ecosystem resilience through mechanisms like the insurance effect ⁵², and underpinning soil and plant health ⁵⁰ – demands their explicit consideration in conservation planning and action. Failure to account for this vast, unseen microbial world means overlooking a major component of Earth's biodiversity and potentially designing restoration and management strategies that are incomplete or ultimately ineffective due to neglecting the foundational microbial processes that sustain ecosystems.

C. Safeguarding the Blueprint: Genetic Diversity & Resilience

Biodiversity encompasses not only the variety of species and ecosystems but also the genetic diversity within species. This genetic variation is the raw material for evolution and adaptation, providing populations with the capacity to respond to environmental changes, diseases, and other pressures.⁴ Preserving genetic diversity is therefore crucial for maintaining ecological resilience – the ability of ecosystems and the species within them to withstand disturbances and maintain essential functions.⁵⁴ Several approaches are employed to safeguard this vital genetic blueprint:

• Genetic Diversity Preservation Techniques:

• Seed Banks: These facilities conserve plant genetic diversity by storing seeds under controlled conditions (typically cold and dry). The Svalbard Global Seed Vault in Norway serves as a global backup, holding over 1.3 million seed samples from genebanks worldwide, safeguarding crop diversity against loss due to disasters, conflict, or other disruptions.⁵⁷ It increasingly includes collections from community-managed seed banks and wild crop relatives, supported by initiatives like the BOLD project.⁵⁷ National and institutional seed banks, like the Millennium Seed Bank (MSB) at the Royal Botanic Gardens, Kew, play a primary role. Kew's MSB holds seeds from over 40,000 wild plant species (over 2.4 billion seeds) collected through a global partnership network, making it the world's most biodiverse seed collection.⁵⁹ These collections are vital resources for research, plant breeding, and restoration.⁵⁷
• Cryopreservation: For organisms whose seeds cannot be banked or for animal genetic resources, cryopreservation (freezing cells or tissues at very low temperatures) is a key technique. It is used to conserve semen, oocytes, embryos, and somatic tissues, particularly for livestock and wildlife conservation.⁶² While crucial, especially for avian species where embryo preservation is difficult ⁶², challenges remain in optimizing and standardizing protocols for different species.⁶² Organizations like the IUCN SSC Animal Biobanking for Conservation Specialist Group work to advance these methods.⁶⁴
• Living Collections (Botanic Gardens, Zoos): Botanic gardens, arboreta, and zoos maintain living collections of plants and animals ex situ (outside their natural habitat). These collections serve research, education, and conservation breeding purposes, sometimes providing source material for reintroductions.⁶¹ However, recent analyses raise concerns about the capacity and focus of these collections. A study analyzing 100 years of botanic garden data suggests that global living plant collections may have collectively reached "peak capacity".⁶⁵ Restrictions on collecting wild plants, partly stemming from the implementation of the Convention on Biological Diversity (CBD), have reportedly hampered the acquisition of new genetic diversity since the early 1990s. Furthermore, the study indicates a historical lack of prioritization for conserving threatened species within these collections.⁶⁵ This necessitates greater collaboration among institutions to function as a coordinated 'meta-collection', sharing data and resources, particularly to support collections in the biodiversity-rich Global South.⁶⁵ Quantifying the diversity held within these collections, potentially using metrics like Hill numbers which can integrate taxonomic, phylogenetic, and functional diversity, is also important.⁶⁶

• Ecological Resilience & Tipping Points: The importance of preserving genetic diversity is amplified by our growing understanding of ecological resilience and tipping points. Resilience refers to the capacity of social-ecological systems to absorb disturbances, adapt to changing conditions, and maintain their fundamental structure and functions.⁵⁴ However, ecosystems are not infinitely resilient. They can reach critical thresholds, or tipping points, beyond which even small additional pressures can trigger abrupt, large-scale, self-amplifying, and often irreversible shifts to a different state.³ Examples of potential ecosystem tipping points (ETPs) include the dieback of the Amazon rainforest, shifts in boreal forest cover, collapse of tropical peatlands, and widespread coral reef die-off.¹⁹ Crossing such tipping points is linked to transgressing planetary boundaries – safe operating limits for key Earth system processes. Currently, six of the nine identified planetary boundaries are considered crossed, including climate change and biosphere integrity (which encompasses biodiversity loss).²⁹ Climate change, coupled with other human pressures like land-use change and pollution, increases the risk of triggering these ETPs, although predicting the exact timing remains deeply uncertain.¹⁹ Genetic diversity within populations is a key factor contributing to their ability to resist or adapt to the pressures that might push them towards a tipping point.

A concerning juxtaposition emerges between the urgent need to conserve genetic diversity and potential limitations in our ex situ conservation infrastructure. While seed banks like Svalbard and Kew's MSB provide invaluable long-term security for a vast number of plant species ⁵⁷, and cryobanking offers solutions for animal genetic resources ⁶², living collections in botanic gardens appear to be facing significant challenges.⁶⁵ Reports of reaching peak capacity, declining acquisition of crucial wild-collected genetic diversity needed for adaptation research and breeding, and a historical lack of focus on threatened species ⁶⁵ suggest a potential bottleneck in this important conservation tool. This limitation arises precisely when the science of ecological resilience and tipping points ¹⁹ makes clear the critical importance of maximizing genetic variation as a buffer against accelerating climate change and other environmental pressures. Ensuring that ex situ conservation efforts, particularly living collections, are adequately resourced, coordinated globally, and strategically focused on capturing and maintaining the genetic diversity most needed for future adaptation is paramount.

III. Global Response: Policy, Governance, and Conservation Action

The escalating biodiversity crisis has prompted significant responses at international, national, and sectoral levels. Landmark agreements aim to set global ambition, while national strategies translate these goals into action. Concurrently, there is growing recognition of the essential roles played by Indigenous Peoples, local communities, and the corporate sector in achieving conservation outcomes.

A. The Kunming-Montreal Framework & Beyond: International Commitments

The primary international policy instrument guiding global biodiversity action is the Kunming-Montreal Global Biodiversity Framework (GBF), adopted by Parties to the Convention on Biological Diversity (CBD) at COP15 in December 2022.³¹ Hailed as a historic agreement, the GBF sets out an ambitious mission: to take urgent action to halt and reverse biodiversity loss by 2030, putting nature on a path to recovery to achieve the vision of living in harmony with nature by 2050.³⁴ The framework comprises four long-term goals for 2050 and 23 action-oriented targets for 2030.³¹

Key GBF Targets for 2030 include:

• Target 2 (Restoration): Ensure that at least 30% of degraded terrestrial, inland water, and coastal and marine ecosystems are under effective restoration.³¹
• Target 3 (30x30): Effectively conserve and manage at least 30% of terrestrial, inland water, and coastal and marine areas, through ecologically representative, well-connected systems of protected areas and other effective area-based conservation measures (OECMs), ensuring equitable governance and respecting IPLC rights.³¹
• Target 5 (Sustainable Use): Ensure that the use, harvesting, and trade of wild species is sustainable, safe, and legal.⁷⁰
• Target 6 (Invasive Species): Reduce the rate of introduction and establishment of invasive alien species by at least 50%.³¹
• Target 15 (Business Accountability): Take measures to ensure that large and transnational companies and financial institutions regularly monitor, assess, and transparently disclose their risks, dependencies, and impacts on biodiversity.⁷⁰
• Target 16 (Sustainable Consumption): Ensure people are encouraged and enabled to make sustainable consumption choices, and significantly reduce the global footprint of consumption.⁷⁰
• Target 18 (Harmful Subsidies): Identify, and eliminate, phase out, or reform incentives, including subsidies, harmful to biodiversity, progressively reducing them by at least $500 billion per year.³¹
• Target 19 (Resource Mobilization): Substantially increase financial resources from all sources (public and private, domestic and international) to implement national biodiversity strategies, mobilizing at least $200 billion per year. This includes increasing international financial flows from developed to developing countries to at least $20 billion per year by 2025 and $30 billion per year by 2030.³¹
• Target 22 (Equitable Participation): Ensure the full, equitable, inclusive, effective, and gender-responsive participation of IPLCs, women, youth, and other stakeholders in decision-making related to biodiversity.⁷⁰

Implementation of the GBF relies on several key mechanisms agreed upon by Parties. National Biodiversity Strategies and Action Plans (NBSAPs) are the principal instruments for national implementation, and Parties were requested to revise or update their NBSAPs to align with the GBF by COP16 (October/November 2024).³¹ A Monitoring Framework, including a set of headline indicators, was adopted to track progress towards the goals and targets consistently across countries.³¹ Resource mobilization remains a critical and contentious issue. COP15 established the Global Biodiversity Framework Fund (GBFF) under the existing Global Environment Facility (GEF) to channel new funding, particularly to developing countries.³¹ Subsequent negotiations at COP16 (including the resumed session in Rome, February 2025) adopted a broader Resource Mobilization Strategy and established a roadmap to decide on a permanent financial mechanism for the Convention by COP18 in 2028.³³

Complementing the CBD framework, the Agreement under the UN Convention on the Law of the Sea on the Conservation and Sustainable Use of Marine Biological Diversity of Areas beyond National Jurisdiction (BBNJ Agreement, or High Seas Treaty) was adopted in June 2023.⁷⁷ This legally binding instrument addresses critical gaps in ocean governance, covering marine genetic resources (including benefit-sharing), area-based management tools (like Marine Protected Areas), environmental impact assessments, and capacity building and technology transfer for activities in areas beyond national jurisdiction.⁷⁷ The agreement opened for signature in September 2023 and will remain open until September 2025; it requires 60 ratifications to enter into force (as of March 2025, there were 21 parties).⁷⁷ A Preparatory Commission is currently working on the practical arrangements for its implementation.⁷⁷

Despite the significant ambition enshrined in the GBF and the BBNJ Agreement, early assessments indicate that implementation is lagging considerably behind the required pace. Many countries have delayed submitting their revised NBSAPs.³¹ Progress reporting on Target 3 (30x30) reveals that while global coverage has increased to 17.6% on land and 8.4% at sea, this is far short of the 30% goal, and crucial data on the effectiveness, connectivity, and equity aspects of these conserved areas is largely missing.⁷² Perhaps most critically, financial commitments fall dramatically short. Initial pledges to the GBFF announced in 2023 were minimal compared to the target of mobilizing $200 billion per year overall, and $20-30 billion per year in international flows.³¹ The continued negotiations on resource mobilization underscore that securing adequate and predictable funding remains a primary obstacle.³³ This reveals a concerning gap between the high-level political consensus achieved in Montreal and the translation of that ambition into concrete national actions and financial commitments needed to halt and reverse biodiversity loss by 2030.

B. National Strategies in Action (NBSAP examples)

National Biodiversity Strategies and Action Plans (NBSAPs) serve as the primary mechanism for countries to translate the global goals and targets of the GBF into national policies, plans, and actions.⁷⁵ Following COP15, all Parties were requested to revise or update their NBSAPs to align with the Kunming-Montreal framework, ideally by COP16 in late 2024.³¹ While many countries faced delays in meeting this timeline, several have launched updated strategies, showcasing diverse approaches to implementation. Regional dialogues and support tools like the Data Reporting Tool (DaRT) and the Bioland Tool for national clearing-house mechanisms aim to assist countries in this process.⁷⁵

Examples of recent national strategies and plans include:

• Brazil: In early 2025, Brazil's National Biodiversity Commission (Conabio) approved 23 new national biodiversity goals for 2025-2030, explicitly aligning with the GBF.⁷⁹ Developed through extensive public consultation, these goals prioritize reducing biodiversity loss through territorial planning and participatory management, notably including a target for zero deforestation across all biomes. Other targets focus on ecosystem restoration, sustainable management, tackling invasive species and pollution, ensuring fair access and benefit-sharing from genetic resources, and significantly boosting biodiversity finance (both domestically and contributing to the global $200 billion target).⁷⁹
• Indonesia: Launched its updated Indonesian Biodiversity Strategy and Action Plan (IBSAP) for 2025-2045 in August 2024.⁸¹ This long-term strategy is integrated with the country's National Long-Term Development Plan (RPJPN) and aligns with the KM-GBF and Sustainable Development Goals (SDGs). Key priorities include holistic management of terrestrial and marine ecosystems, sustainable and equitable utilization of biodiversity, strengthening cross-sectoral collaboration, developing innovative financing, and integrating traditional knowledge from local communities.⁸¹
• France: Unveiled its "Stratégie nationale biodiversité 2030" in late 2023, covering the period 2022-2030.⁸² Developed collaboratively with territories, citizens, and businesses, it aligns with the GBF and EU objectives. The strategy outlines 40 specific measures across four axes: reducing pressures, restoring biodiversity, mobilizing actors, and securing means of implementation, backed by €1 billion in state funding.⁸²
• Germany: While details on a fully revised post-COP15 NBSAP were not available in the reviewed sources (official CBD country profile inaccessible ⁸³), Germany launched its Federal Action Plan on Nature-Based Solutions for Climate and Biodiversity (Aktionsprogramm Natürlicher Klimaschutz - ANK) in June 2023.⁸⁵ This plan, containing 69 measures for ecosystems like forests, peatlands, and coastal areas, explicitly integrates NbS into national strategies to contribute to both climate mitigation/adaptation and biodiversity goals.⁸⁵
• Thailand: The country's NBSAP for 2023-2027 focuses on three core strategies: strengthening conservation efforts (improving habitat/species protection, expanding protected areas), promoting sustainable and equitable use of biodiversity resources (in agriculture, forestry, tourism, fisheries) for local community benefit, and mainstreaming biodiversity considerations into all national and sectoral policies and development plans.⁸⁶
• European Union: Progress within the EU has been mixed, with only Spain and Hungary having submitted fully revised post-COP15 NBSAPs by mid-2024, although other member states were actively revising their plans.³¹

The varied pace and focus of these national strategies reflect the differing ecological contexts, socioeconomic priorities, institutional capacities, and political landscapes across countries. While nations like Brazil, Indonesia, and France demonstrate clear efforts to align national planning with the GBF's comprehensive targets ⁷⁹, the global lag in NBSAP submission ³¹ highlights the challenges many countries face in translating global commitments into actionable national frameworks. The specific emphases also differ – Brazil's strong focus on halting deforestation and mobilizing finance ⁷⁹, Indonesia's integration with long-term development planning ⁸¹, and Germany's prominent use of a Nature-based Solutions framework ⁸⁵ – illustrating how global goals are interpreted and prioritized within unique national circumstances.

C. Empowering Stewards: Indigenous Peoples and Local Communities (IPLCs)

There is unequivocal and growing recognition within the international conservation community that Indigenous Peoples and Local Communities (IPLCs) are essential partners and leaders in safeguarding biodiversity.⁸⁷ Lands managed by IPLCs often exhibit biodiversity levels comparable or even superior to formally designated protected areas, acting as crucial refuges for species and ecosystems.¹³ While the often-cited statistic that 80% of the world's remaining biodiversity resides within IPLC territories may lack rigorous verification ⁸⁸, it nonetheless reflects the significant overlap between areas of high biodiversity and lands under traditional stewardship. The GBF explicitly acknowledges this role, with Target 22 calling for the full and effective participation of IPLCs in biodiversity decision-making, respecting their rights and knowledge.⁷⁰

Central to IPLC stewardship is Traditional Ecological Knowledge (TEK) – the cumulative body of knowledge, practices, and beliefs evolved over generations through intimate interaction with the environment.⁸⁸ TEK encompasses deep understanding of local ecosystems, sustainable resource management techniques, and often, cultural and spiritual values that foster respect for nature and intergenerational responsibility.⁹¹ Integrating TEK with scientific knowledge can lead to more effective, equitable, and locally relevant conservation strategies.⁸⁸ While the integration of TEK into policy and practice is increasing, challenges remain in ensuring this is done respectfully, ethically, and in ways that genuinely empower IPLC communities and protect their intellectual property rights.⁹¹

Numerous initiatives demonstrate the success and potential of IPLC-led conservation:

• Territorial Monitoring and Defense: In the Brazilian Amazon, a collaboration between Kanindé (an ethno-environmental NGO) and several Indigenous communities (including the Uru-Eu-Wau-Wau) utilizes satellite data, drones, and the SMART monitoring tool to empower Indigenous monitors to detect and document illegal deforestation, logging, and mining within their territories. This information has been used to file legal complaints and prompt government enforcement actions, directly contributing to the protection of these highly biodiverse lands.¹³
• Ecosystem Restoration: In the European Arctic, the Skolt Sámi have applied their traditional knowledge to restore river ecosystems damaged by past logging activities, successfully reviving habitats for cold-dependent fish species.⁹²
• Co-Management and Indigenous Protected Areas: In Canada's Arctic, the Pikialasorsuaq Commission, guided by Inuit knowledge, is developing strategies for managing a vital polynya (area of year-round open water) critical for marine mammals and Inuit livelihoods.⁹² WWF-Canada supports Inuit communities in Nunavut in establishing community-led conservation areas.⁹³ Globally, there is an increasing trend of IPLCs declaring their own Indigenous Protected and Conserved Areas (ICCAs), or "territories of life".⁸⁹
• Dedicated Funding Mechanisms: Recognizing the need for direct support, the GEF-8 Inclusive Conservation Initiative (ICI) aims to channel 80% of its grant funding directly to IPLC organizations for their self-determined conservation priorities and capacity building. The initiative targets improved management across hundreds of thousands of hectares of terrestrial and marine areas and restoration of degraded lands.⁸⁷

Despite this progress, significant challenges persist. The legacy of "fortress conservation" – exclusionary models that forcibly displaced IPLCs from their ancestral lands in the name of protection – continues to cast a shadow, and human rights violations linked to conservation projects still occur.⁸⁹ Ensuring secure land and resource tenure rights for IPLCs is fundamental, as is establishing mechanisms for equitable benefit-sharing from conservation initiatives and the use of genetic resources or associated traditional knowledge.⁸⁷ Moving forward requires a paradigm shift away from top-down approaches towards genuine partnerships that respect IPLC autonomy, recognize their rights, provide direct and flexible funding, and integrate TEK as a valid and essential knowledge system alongside science.⁸⁷

The convergence of evidence demonstrating the effectiveness of IPLC stewardship ¹³, the increasing inclusion of IPLC rights and participation in international frameworks like the GBF ⁷⁰, and the emergence of dedicated funding mechanisms like the GEF-8 ICI ⁸⁷ signals a positive trend. However, realizing the full potential of IPLC leadership in conservation necessitates dismantling historical inequities and systemic barriers. It requires moving beyond tokenistic engagement to truly empower communities through secure rights, adequate resources, and respect for their knowledge systems, thereby fostering conservation approaches that are both more effective and more just.⁸⁹

D. Corporate Accountability: Disclosure, ESG, and Nature Positive

The role and responsibility of the private sector, particularly large corporations and financial institutions, in addressing biodiversity loss has gained significant prominence.⁷⁴ There is mounting pressure from policymakers (reflected in GBF Target 15 mandating assessment and disclosure ⁷⁰), investors (through initiatives like Nature Action 100 and the Finance for Biodiversity Pledge ⁷⁴), regulators (such as the EU's Corporate Sustainability Reporting Directive - CSRD ⁹⁶), and consumers ⁷⁴ for businesses to understand, report on, and mitigate their impacts and dependencies on nature.

In response, a rapidly evolving ecosystem of frameworks and standards is emerging to guide corporate action:

• Taskforce on Nature-related Financial Disclosures (TNFD): Launched in September 2023, the TNFD provides a framework for organizations to report on evolving nature-related issues (dependencies, impacts, risks, and opportunities), modeled after the successful Task Force on Climate-related Financial Disclosures (TCFD).⁷⁴ It emphasizes assessing impacts and dependencies at specific locations, recognizing the place-based nature of biodiversity.⁹⁶ TNFD has released sector-specific guidance (e.g., for Food & Agriculture in January 2025) to help companies apply the framework.⁹⁶
• Science Based Targets Network (SBTN): Complementary to TNFD's focus on disclosure, SBTN is developing methodologies for companies to set credible, science-based targets for reducing their impacts on nature, covering areas like freshwater use, land use change, and direct impacts on biodiversity.⁷⁴ SBTN guidance helps companies prioritize actions in ecologically important locations.⁹⁴
• Environmental, Social, and Governance (ESG) Integration: Biodiversity and nature-related metrics are increasingly being incorporated into ESG ratings and investment analyses.⁹⁷ Investors are recognizing nature loss as a material financial risk, ranking second only to climate change in importance according to some investor networks like FAIRR.⁹⁵ Key ESG trends include greater scrutiny of supply chain impacts, focus on climate adaptation and resilience (often linked to ecosystem health), the use of AI for improved reporting, and rising litigation risk related to greenwashing or unmet environmental commitments.⁹⁷
• High-Level Business Actions on Nature (ACT-D): To promote alignment between these various frameworks, organizations like Business for Nature, WBCSD, WEF, and WWF have collaborated on the ACT-D framework (Assess, Commit, Transform, Disclose). This provides a high-level logic for corporate nature action, integrating key elements from TNFD, SBTN, and other guidance.⁷⁴

The concept of becoming "Nature Positive" – contributing to the global goal of halting and reversing biodiversity loss by 2030 – has gained traction within the business community.⁷⁴ Many leading companies are publicly acknowledging nature-related issues and setting targets. Analysis of Fortune Global 500 companies shows a significant increase in nature-related commitments between 2022 and 2024, with 76% mentioning biodiversity and 71% mentioning forests in their 2024 reporting.⁹⁵ Organizations like the World Business Council for Sustainable Development (WBCSD) are actively working with member companies through preparer groups and roadmaps to help them assess impacts, set science-based targets using SBTN guidance, and align with TNFD disclosure recommendations.⁷⁴ Examples of corporate initiatives include Nestlé's commitment to achieve deforestation-free primary supply chains by 2025 and its engagement in sustainable landscape projects ¹⁰², and Unilever's targets for implementing regenerative agriculture practices on 1 million hectares and maintaining deforestation-free sourcing for key commodities.¹⁰⁴ Veolia has integrated biodiversity objectives into its corporate performance metrics.¹⁰⁶

This rapid evolution signifies a shift where corporate engagement with nature is moving from a niche concern towards becoming a mainstream business imperative. The proliferation of disclosure frameworks (TNFD), target-setting guidance (SBTN), and integration into ESG assessments ⁹⁴ provides structure and drives increasing corporate commitment.⁹⁵ However, significant challenges remain. Ensuring that these commitments translate into genuine, measurable, positive impacts on the ground requires robust data, traceability across complex global value chains, and scientifically sound methodologies for target-setting and impact measurement – areas where standardization is still developing and the risks associated with simplifying complex ecological realities (as seen with 'units of nature' ³⁴) persist. Moving beyond disclosure to achieve genuine business transformation across entire value chains, while avoiding greenwashing ⁹⁷, remains the critical next step for the corporate sector's contribution to a nature-positive future.

IV. Biodiversity's Intersections: Tackling Global Challenges Together

Biodiversity loss is not an isolated environmental problem; it is deeply intertwined with other major global challenges, including climate change, food security, pandemic prevention, and sustainable urbanization. Addressing these crises effectively requires recognizing and managing these complex interdependencies.

A. The Climate-Biodiversity Nexus

The links between climate change and biodiversity loss are profound and reciprocal. Climate change is unequivocally a major direct driver of biodiversity loss, altering habitats, shifting species distributions, changing phenology (the timing of life cycle events), and increasing extinction risk.⁶ Simultaneously, the degradation of ecosystems, particularly forests, wetlands, and soils, impairs their ability to sequester carbon, thereby accelerating climate change.²⁹ This creates a dangerous feedback loop, where climate change drives biodiversity loss, which in turn worsens climate change.²⁹ Scientists warn of potential cascading impacts and the crossing of critical tipping points in both climate and ecological systems.¹⁹

The impacts of observed warming are already severe. The IPCC's Sixth Assessment Report (AR6) confirms that climate change has spurred unprecedented changes globally, with adverse impacts on ecosystems more extreme than previously anticipated.¹⁸ Risks escalate with every fraction of a degree of warming. Even limiting warming to 1.5°C poses significant threats to vulnerable ecosystems like coral reefs (experiencing mass bleaching events due to marine heatwaves ¹⁴) and drylands.¹⁸ Overshooting 1.5°C, even temporarily, significantly increases the likelihood of severe and irreversible impacts, including local species extinctions and potential large-scale ecosystem collapse, such as forest dieback or irreversible ice sheet melt leading to significant sea-level rise.¹⁸ Observed effects already include widespread shifts in species' geographical ranges and altered timing of seasonal events like flowering and migration.¹¹¹

Conversely, biodiversity and healthy ecosystems offer powerful solutions for tackling climate change. Nature-based Solutions (NbS) and Ecosystem-based Adaptation (EbA) involve protecting, sustainably managing, and restoring ecosystems to address societal challenges, including climate change mitigation and adaptation.⁸⁵ For mitigation, ecosystems like forests, peatlands, mangroves, and healthy soils act as vital carbon sinks. Protecting and restoring these ecosystems can provide a significant portion (potentially up to 37% by 2030) of the cost-effective mitigation needed to meet Paris Agreement goals.⁹² For adaptation, intact ecosystems enhance resilience and reduce vulnerability to climate impacts. For example, coastal ecosystems like mangroves and coral reefs buffer shorelines from storm surges; wetlands absorb floodwaters; forests stabilize slopes and regulate water flow; and diverse agricultural landscapes are more resilient to drought and pests.²⁵ These approaches typically deliver substantial co-benefits, including biodiversity conservation, improved water quality, enhanced livelihoods, and human health benefits.¹¹² Germany's National Action Plan for Natural Climate Protection (ANK) exemplifies the integration of NbS into national strategy.⁸⁵

The scientific evidence clearly demonstrates that climate change and biodiversity loss must be addressed in an integrated manner. Solutions that benefit both climate (mitigation and adaptation) and biodiversity, such as NbS and EbA, are readily available and often highly effective.²⁹ However, the implementation of these integrated approaches is often hampered by fragmented governance structures, where climate and biodiversity policies are developed and managed in separate silos, and by inadequate or misaligned financial flows.⁶ Realizing the full potential of nature-based climate solutions requires mainstreaming NbS and EbA into core climate policies (like Nationally Determined Contributions - NDCs under the Paris Agreement), national biodiversity plans (NBSAPs), and broader development strategies. This must be accompanied by dedicated and integrated funding mechanisms that recognize the interconnectedness of these global challenges.¹¹²

B. Feeding the World Sustainably: Biodiversity and Food Security

The relationship between biodiversity and food security is fundamental yet complex. Agriculture and food production depend heavily on biodiversity for essential ecosystem services like pollination, soil fertility maintenance (driven by soil microbes), pest control (provided by natural predators), and the genetic diversity within crops and livestock that allows adaptation to changing conditions.¹¹⁵ However, the dominant model of industrial agriculture has become a primary driver of biodiversity loss globally through habitat conversion (especially deforestation), expansion of monocultures, pollution from fertilizers and pesticides, and depletion of water resources.²⁹ The IPBES Nexus Assessment explicitly warns that prioritizing food production through unsustainable means leads to severe negative trade-offs for biodiversity, water quality, and climate regulation.⁶

Conserving and utilizing agrobiodiversity – the variety of plants, animals, and microorganisms used directly or indirectly for food and agriculture – is critical for building resilient and sustainable food systems.¹¹⁵ This diversity, developed over millennia by farmers, provides options for adapting crops to climate change, pests, and diseases, and enhances nutritional diversity in human diets.¹¹⁵ The erosion of agrobiodiversity due to the homogenization of farming systems and reliance on a narrow range of high-yield varieties poses a significant risk to long-term food security.¹¹⁵

Approaches like agroecology and regenerative agriculture offer pathways to produce food while supporting biodiversity and ecosystem health.¹⁰⁴ These systems emphasize principles such as crop diversification (polyculture), integration of trees (agroforestry), maintaining soil cover, reducing reliance on synthetic inputs, enhancing soil microbial life, and integrating livestock sustainably.¹¹⁶ By mimicking natural ecosystem processes, these practices can enhance soil fertility, improve water retention, sequester carbon, support pollinators and other beneficial organisms, and increase resilience to climate shocks.¹¹⁶ Corporate initiatives, such as Unilever's projects aiming to implement regenerative practices on 1 million hectares, are exploring the scalability of these approaches, with some early results indicating potential reductions in greenhouse gas emissions.¹⁰⁴ Supporting diverse, localized 'territorial' food markets can also enhance food access and resilience.¹¹⁸

Addressing the food-biodiversity nexus also requires changes in consumption patterns. The high environmental footprint of industrial meat production (land use, water use, GHG emissions) means that shifting towards more plant-rich diets in regions with high meat consumption can significantly reduce pressure on biodiversity.⁶ Furthermore, reducing the vast amount of food waste generated globally (estimated at around one-third of all food produced) is essential for alleviating pressure on land and resources.⁹⁸

Given that the food system is a dominant driver of biodiversity loss ²⁹ and water use, and a major contributor to climate change, its transformation is central to achieving global sustainability goals. The IPBES Nexus report's findings on the negative consequences of prioritizing food production in isolation ⁶ underscore the need for systemic change. Halting and reversing biodiversity loss requires a fundamental shift in how food is produced – moving towards practices like agroecology and regenerative agriculture that work with nature rather than against it.¹¹⁵ This must be coupled with efforts to promote sustainable consumption patterns, including dietary shifts and waste reduction.⁶ Achieving this transformation will necessitate supportive policies, investment in sustainable practices, and addressing the socioeconomic factors that influence both farmer adoption and consumer choices.¹¹⁵

C. Preventing the Next Pandemic: Ecosystem Integrity and One Health

The COVID-19 pandemic starkly highlighted the intimate connections between human health, animal health, and the state of the environment. The One Health approach has emerged as a critical framework for understanding and addressing health threats at this interface.¹²⁰ It is an integrated, unifying approach that recognizes the interdependence of the health of people, domestic and wild animals, plants, and the wider environment, including ecosystems.¹²⁰ A key application of One Health is in preventing pandemics, as the majority of emerging infectious diseases (EIDs) in humans are zoonotic, meaning they originate in animals.¹²¹

Scientific evidence increasingly links the degradation of ecosystems and loss of biodiversity to an increased risk of zoonotic disease spillover.⁸⁷ Key drivers of biodiversity loss – such as habitat destruction and fragmentation due to land-use change (e.g., deforestation for agriculture), climate change altering species distributions and interactions, and the global wildlife trade – disrupt natural ecosystems and increase the frequency and intensity of contact between wildlife, livestock, and humans.¹²¹ These disruptions create opportunities for pathogens to jump from their natural animal hosts into human populations.¹²¹ Specific examples illustrate these pathways: the emergence of Hendra virus in Australia has been linked to habitat loss forcing fruit bats (the natural hosts) into closer contact with horses and humans; Lyme disease emergence in the northeastern US is associated with forest fragmentation that favors white-footed mice (competent hosts for the Lyme bacterium) over other species.¹²¹ Studies indicate that the rate of zoonotic spillover events has been increasing in recent decades.¹²¹

Preventing future pandemics therefore requires addressing these shared upstream drivers of both biodiversity loss and disease emergence.¹²¹ This involves protecting intact ecosystems, restoring degraded habitats, managing landscapes to minimize high-risk interfaces between wildlife and humans/livestock, regulating the wildlife trade, and tackling climate change.¹²¹ However, significant gaps remain in our understanding and capacity to predict and prevent spillover events. Surveillance and monitoring of pathogens in wildlife populations are insufficient globally, particularly in biodiversity hotspots where spillover risk may be highest.¹²¹ Early detection and rapid response mechanisms are crucial but challenging to implement effectively.

The recognition, framed by the One Health approach ¹²⁰ and supported by research on EID drivers ¹²¹, that ecosystem integrity is fundamental to human health security represents a significant shift. It reframes biodiversity conservation not merely as an environmental objective but as a critical investment in global public health and pandemic prevention. Actions taken to protect and restore biodiversity – such as establishing protected areas, combating deforestation, managing wildlife trade sustainably, and restoring degraded landscapes – directly contribute to reducing the risk of future pandemics by maintaining the ecological barriers and balances that normally limit pathogen transmission. This understanding adds a powerful public health imperative to existing environmental and economic arguments for robust conservation action.

D. Greening Our Cities: Urban Biodiversity and Nature-Positive Development

Urban areas are expanding rapidly worldwide, covering roughly 3% of the Earth's land surface but exerting a disproportionately large ecological footprint through resource consumption, pollution, and habitat alteration beyond their boundaries.⁴¹ This expansion is a major driver of habitat fragmentation and biodiversity loss globally.⁴¹ Yet, cities themselves are not devoid of nature; they can harbor significant biodiversity and provide vital ecosystem services to their inhabitants.⁴¹ Urban environments can offer resources like food, water, nesting sites, and milder microclimates that allow certain species to thrive, sometimes supporting higher levels of diversity than surrounding intensively managed agricultural landscapes.⁴¹

Recognizing this potential, numerous initiatives are underway globally to enhance urban biodiversity and integrate nature into city planning – a concept often referred to as nature-positive development.¹²²

• City Networks and Commitments: The C40 Cities Climate Leadership Group launched the Urban Nature Accelerator in 2021, with 41 signatory cities committing to ambitious targets for increasing and enhancing green and blue spaces by 2030.¹²² The goals are to reduce climate risks (particularly urban heat and flooding), support ecosystem services, and ensure equitable access to nature for all residents. Cities are implementing diverse actions: Quezon City added 63 new parks; Guadalajara opened 28 urban gardens; Bogotá created over 60,000 green jobs related to nature interventions; Delhi aims to increase its green cover from 23% to 25%; and cities like Copenhagen and San Francisco have secured millions in funding for biodiversity and tree planting projects.¹²² Challenges remain, particularly in effectively monitoring and evaluating the quantity and quality of urban nature.¹²²
• Nature-Positive Projects: Specific projects showcase how integrating nature can deliver multiple benefits. Examples reported by CDP-ICLEI Track include green housing initiatives for vulnerable communities in Evanston, Illinois; sustainable wastewater management involving indigenous communities along the Acai River in Jayapura, Indonesia; and women-led conservation efforts focused on nature-based enterprises like apiculture in Siaya County, Kenya.¹²³
• Community Gardens: These spaces, often managed collectively by local residents, have been shown to significantly benefit urban biodiversity. Studies indicate they can support substantially more pollinator species (up to 50% more) compared to traditional ornamental parks due to greater plant diversity.¹²⁴ They also tend to have healthier soils with more beneficial microbes.¹²⁵ Beyond biodiversity, community gardens provide educational opportunities, foster community cohesion, and can improve local food access.¹²⁴

As the global population becomes increasingly urbanized ⁴¹, cities represent critical arenas where the battle for biodiversity will be partly fought and won. Integrating nature – through parks, green roofs, bioswales, urban forests, community gardens, and nature-based infrastructure – is essential not only for conserving local species and providing habitat connectivity ¹²⁴ but also for enhancing climate resilience (mitigating heat islands, managing stormwater ¹²²) and improving the physical and mental well-being of urban dwellers. The growing commitment from city networks like C40 ¹²² and the emergence of innovative local projects ¹²³ suggest that cities can transform from being primarily drivers of biodiversity loss to becoming hubs of nature-positive innovation and action.

V. Beacons of Hope: Conservation Successes and Restoration Triumphs

Amidst the concerning trends of biodiversity loss, numerous success stories demonstrate that dedicated conservation and restoration efforts can yield positive results, bringing species back from the brink and healing damaged ecosystems. These examples provide valuable lessons and inspiration for scaling up action globally.

A. Bringing Species Back from the Brink

Targeted conservation programs have successfully recovered populations of species that were once critically endangered or even extinct in the wild. These recoveries often result from sustained, multi-faceted efforts addressing the specific threats faced by each species:

• Addressing Exploitation and Persecution: The American Alligator, once listed under the US Endangered Species Act due to overhunting and habitat loss, recovered sufficiently to be delisted just 20 years later, thanks to legal protection and habitat management.¹²⁶ Similarly, the Bald Eagle and Peregrine Falcon populations in North America plummeted due to poisoning from the pesticide DDT. Following the US ban on DDT in 1972, combined with legal protections (like the Bald Eagle Protection Act and Migratory Bird Treaty Act) and captive breeding programs for falcons, both species have made remarkable recoveries and are now classified as Least Concern by IUCN.¹²⁶ Anti-poaching efforts combined with population management and monitoring have been crucial for the steady increase in Southwestern Black Rhino numbers in southern Africa.¹²⁶ The Giant Panda's recovery from Endangered to Vulnerable status was driven by intensive efforts in China, including a ban on trade in panda skins (facilitated by CITES listing), habitat protection through a network of reserves (now being consolidated into a massive national park), and captive breeding programs.¹²⁶
• Habitat and Prey Restoration: The recovery of the Iberian Lynx from Critically Endangered to Vulnerable status involved intensive efforts in Spain and Portugal to restore populations of its primary prey, the European rabbit, alongside captive breeding and reintroduction programs.¹²⁶ The Azores Bullfinch, endemic to a small area in the Azores, benefited from habitat restoration within a Special Protected Area, including removal of invasive plants and replanting of native species, alongside legal protection and monitoring.¹²⁶ Dam removal has been key to the revival of River Herring populations in Maine (USA), with runs increasing from near zero to millions of fish returning to spawn in newly accessible upstream habitats.¹²⁷ Similarly, dam removal on Washington's Elwha River allowed for the reopening of a ceremonial and subsistence fishery for the Lower Elwha Klallam Tribe in 2024.¹²⁷ Habitat restoration efforts were also key to the recovery of the Apache Trout in Arizona, allowing it to be removed from the endangered species list.¹²⁷
• Combined Approaches: The downlisting of the Saiga Antelope from Critically Endangered to Near Threatened resulted from comprehensive government and community-led initiatives in Central Asia tackling poaching and other threats.²² The Scimitar-horned Oryx, previously Extinct in the Wild, was successfully reintroduced into protected areas in Chad through a major international effort involving captive breeding and careful management, leading to its downlisting to Endangered.²² Restrictions on fishing activities and designation of critical habitats helped the recovery of Steller Sea Lion populations in parts of their range, leading to a Near Threatened classification.¹²⁶

These examples consistently demonstrate that species recovery is possible but rarely achieved through a single intervention. Success typically requires a combination of strategies tailored to the specific threats involved. Legal protection provides a foundation, but often needs to be coupled with active habitat management or restoration, direct action against exploitation (anti-poaching, trade bans, fishing restrictions), addressing pollution sources (like DDT), and sometimes, intensive measures like captive breeding and reintroduction. The involvement of multiple actors – government agencies, conservation NGOs, research institutions, local communities, and international collaborations – is also a common feature of successful recovery programs.

B. Healing Ecosystems: Innovative Restoration Projects

Beyond focusing on individual species, large-scale ecosystem restoration aims to repair degraded landscapes and seascapes, restoring ecological functions and benefiting multiple species simultaneously. This aligns with GBF Target 2 (30% restoration by 2030) ³¹ and the goals of the UN Decade on Ecosystem Restoration (2021-2030).¹²⁸ International standards and principles, such as those developed by the Society for Ecological Restoration (SER) and partners for the UN Decade, provide guidance for effective, standards-based restoration.⁷¹ Numerous projects globally are demonstrating innovative approaches and achieving measurable outcomes:

• Large-Scale Government Initiatives: The Great Lakes Restoration Initiative (GLRI) in the US, launched in 2010, represents a major interagency effort.¹²⁹ With over $575 million channeled through the US Fish and Wildlife Service alone, the initiative supports hundreds of projects annually. In 2023, 93 projects restored over 4,000 acres of habitat and addressed invasive species threats.¹²⁹ Specific projects include restoring shoreline, marsh, and wetland habitat at Sugar Island to benefit fish and wildlife.⁴³ This coordinated effort benefits the region's $18 billion recreation economy alongside ecological health.¹²⁹
• Landscape Mosaic Restoration: The Wild Ingleborough project in the UK takes a landscape approach to restoring a mosaic of habitats (native woodland, heather moorland, peat bog) in the Yorkshire Dales.¹³ Using a combination of active tree planting (85,000 trees planted to connect fragmented woodlands) and promoting natural regeneration (e.g., by shifting from sheep to less intensive cattle grazing), the project aims to enhance biodiversity while supporting wildlife-friendly farming practices across 230 hectares of woodland and 62 hectares of peat bog.¹³
• Targeted Ecosystem Restoration (SER Examples): The SER's 2023 list of standards-based restoration projects showcases diverse initiatives globally.¹³⁰ Examples include: restoring wetland habitats for White Storks in Sweden and rare wetland types in Virginia; expanding ancient coppice forest in Denmark for biodiversity and cultural heritage; restoring native grasslands and pollinator habitats in Texas and Arizona; re-creating oxbow wetlands along the Boone River in Iowa for biodiversity, flood mitigation, and water quality; restoring sagebrush-steppe habitat in Washington; and using floating wetlands and biofilters for lake restoration in Malaysia.¹³⁰
• Forest Restoration: Various projects focus on restoring forest ecosystems, often engaging private landowners. NFWF-funded projects in the US Southeast, for instance, aim to restore thousands of acres of longleaf pine and oak forests through planting, prescribed burning, and landowner engagement.¹³¹ Research suggests forest restoration can significantly increase soil methane uptake, contributing to climate mitigation.⁴²
• Marine Debris Removal: Initiatives like 4ocean demonstrate tangible results in addressing pollution, having collected 30 million pounds of trash from marine environments.¹³² NFWF also funded large-scale marine debris removal in Alabama following Hurricane Sally.¹³¹

Successful restoration projects increasingly exhibit common characteristics. They often involve strong partnerships between government agencies, NGOs, research institutions, and local communities or landowners, leveraging diverse expertise and resources (e.g., GLRI partnerships ¹²⁹, SER project collaborations ¹³⁰). They apply ecological principles informed by science, such as using native species, removing invasives, and restoring natural processes (like river flows or fire regimes where appropriate), often guided by restoration standards.⁷¹ Furthermore, many successful projects aim for multiple outcomes beyond just biodiversity, integrating goals related to climate mitigation (carbon sequestration ¹³⁰), climate adaptation (flood control, water quality ¹³⁰), economic benefits (jobs, sustainable livelihoods ¹²⁹), and cultural values.¹³⁰ Funding often comes from a mix of sources, including dedicated government programs (like GLRI), NGO fundraising, and corporate partnerships (e.g., SER's work with Microsoft ¹³⁰). This trend towards integrated, collaborative, science-based, and multi-benefit restoration holds promise for scaling up efforts to meet ambitious global targets.

C. Community-Led Conservation Victories

Empowering local communities, including but not limited to IPLCs, is increasingly recognized as a cornerstone of effective and sustainable conservation. When communities have agency, secure rights, and access to resources and tools, they can become powerful stewards of their local environments.

• Indigenous Stewardship: As detailed previously (Section III.C), IPLC-led initiatives in the Amazon ¹³ and the Arctic ⁹² demonstrate effective territorial monitoring, resource management based on TEK, and ecosystem restoration. The recognition of customary forest rights in Indonesia also empowers communities in forest management.¹³
• Community Gardens and Urban Greening: Community gardens provide tangible biodiversity benefits in urban settings, supporting pollinators and soil health, while also serving as educational hubs and fostering environmental awareness.¹²⁴ Projects like the Lents International Community Garden in Portland showcase successful shared management models.¹²⁵ Earth5R's initiative in India turned organic waste into compost for urban farming, reducing landfill waste and enhancing soil biodiversity.¹²⁵
• Local Conservation Groups: Numerous examples highlight the impact of local volunteer groups and non-profits. The Loudoun Wildlife Conservancy's restoration of the JK Black Oak Wildlife Sanctuary in Virginia ¹³⁰, the Friends of the Forest Preserves' Conservation Corps program engaging volunteers in restoring 14,000 acres near Barrington, Illinois ¹³⁰, and the Malaga-Colockum Community Council's work on shrub-steppe restoration in Washington ¹³⁰ all demonstrate the power of grassroots action in habitat management and restoration.
• Engaging Private Landowners: Conservation success often depends on engaging private landowners, who manage vast tracts of land. NFWF grants frequently support projects that work directly with farmers and forest owners to implement conservation practices on their properties, such as restoring native grasslands or improving forest management for wildlife.¹³¹

These diverse examples underscore a crucial principle: local communities are often best positioned to implement and sustain conservation actions when they are empowered and supported. The Amazon monitoring project ¹³ vividly illustrates how providing technology and training enabled Indigenous communities to effectively defend their territories against illegal activities. Community gardens demonstrate how collective local action can create valuable biodiversity refuges in urban landscapes.¹²⁴ The success of local conservation groups ¹³⁰ highlights the dedication and impact of citizen volunteers. This pattern suggests that devolving decision-making power, ensuring secure rights (especially land tenure for IPLCs), and providing adequate financial and technical resources directly to the local level are key strategies for unlocking significant conservation potential and ensuring long-term stewardship.

D. Technology as an Ally: Conservation Tech Breakthroughs

Technological advancements are providing conservationists with powerful new tools for monitoring wildlife, managing habitats, combating illegal activities, and engaging the public. When integrated effectively, technology can significantly enhance conservation outcomes.

• eDNA Applications: As discussed in Section II.A, eDNA analysis is proving highly effective for detecting rare, elusive, or invasive species, enabling more targeted and efficient management interventions. Examples include monitoring endangered yellow mud turtles ³⁸, detecting cryptic forest mammals and bats ³⁹, and providing early warning for invasive spotted lanternflies.³⁹ Large-scale eDNA monitoring programs, like the one developed in New Zealand, are creating comprehensive biodiversity databases from environmental samples.³⁹
• Remote Sensing for Monitoring: Satellite imagery, drones, and other remote sensing tools are invaluable for monitoring habitat change, restoration progress, and environmental threats over large areas. Applications include tracking deforestation and fire patterns in the Amazon ¹¹, monitoring the effectiveness of wetland and shoreline restoration in the Great Lakes ⁴³, assessing vegetation recovery after restoration interventions ⁴², mapping critical marine habitats in the Arctic (ArcNet project) ⁹³, and improving the monitoring of harmful algal blooms.⁴³
• AI in Conservation: Artificial intelligence is increasingly used to analyze complex data streams and automate tasks. In anti-poaching, AI powers real-time alert systems by analyzing camera trap images (TrailGuard AI) or data from smart collars on animals like rhinos, allowing for rapid ranger deployment.⁴⁶ AI algorithms analyze vast numbers of camera trap photos or drone images to monitor wildlife populations (e.g., koalas).⁴⁶ AI also enhances citizen science platforms like Merlin Bird ID by enabling sound and photo identification based on massive datasets contributed by users via eBird.¹³³ Microsoft's AI for Earth program aims to leverage AI for broader environmental sustainability goals, including water conservation through AI-powered leak detection (FIDO) ¹³⁵, although specific biodiversity project impacts require further reporting.¹³⁵

While these technologies offer immense potential, their effectiveness hinges on how they are integrated into broader conservation strategies. Technology is a tool, not a panacea. Successful applications often involve combining technological data with field knowledge and local expertise, as seen in the Amazon monitoring project where satellite data guides ground-truthing by Indigenous monitors using drones and apps.¹³ The anti-poaching systems rely on AI detection triggering a rapid human response from rangers.⁴⁷ Furthermore, the accessibility and usability of these tools are critical. User-friendly apps like Merlin Bird ID ¹³³ successfully engage a wide audience, while complex data processing requirements for some technologies (like UAV imagery ⁴¹) can be a barrier if adequate resources and training are not available. Ensuring that conservation technology is not only powerful but also practical, affordable, and accessible to practitioners, managers, and communities on the ground is key to maximizing its positive impact.

VI. Framework for Action: Empowering Individuals and Organizations

Halting and reversing biodiversity loss requires action at all levels, from international agreements and national policies down to the choices made by individuals and organizations in their daily lives and operations. This section outlines practical, evidence-based actions that can be taken to support biodiversity conservation.

A. Conscious Consumption: Choices that Protect Biodiversity

Individual consumption patterns have a significant collective impact on biodiversity, primarily through the resource extraction, land use, pollution, and greenhouse gas emissions associated with the production and transportation of goods and services.⁹⁸ Making more conscious choices can help reduce this footprint:

• Reduce Overall Consumption: The most fundamental step is to consume less. Buying fewer products, repairing items instead of replacing them, and avoiding unnecessary purchases directly reduces demand for resources and energy.¹¹⁹
• Food Choices: Given the large impact of food systems (Section IV.B), dietary choices are critical. Reducing the consumption of meat (especially beef) and dairy products, which have high land, water, and greenhouse gas footprints, and shifting towards more plant-rich diets is a major positive step.⁹⁸ Choosing seasonal and locally produced food can reduce transportation emissions and support local farmers who may use more sustainable practices.⁹⁸ Embracing dietary diversity beyond a few staple crops also supports agrobiodiversity.⁹⁸ Minimizing food waste through better planning, using leftovers, and composting is essential, as significant resources are embedded in wasted food.⁹⁸
• Product Choices: When purchasing goods, look for products made from sustainable or recycled materials.¹¹⁹ Prioritize durability and repairability – "life cycle thinking" – over cheap, disposable items.¹¹⁹ Seek out credible third-party certifications that indicate adherence to environmental and social standards. Examples include Fairtrade (fair wages, sustainable practices, often for coffee, chocolate, tea) ¹⁰⁷, Rainforest Alliance Certified (biodiversity conservation, sustainable livelihoods, often for coffee, tea, cocoa) ¹⁰⁷, USDA Organic or equivalent national organic labels (reduced synthetic inputs, soil health, biodiversity conservation) ¹⁰⁷, Forest Stewardship Council (FSC) for paper and wood products (responsible forest management) ¹¹⁹, and Marine Stewardship Council (MSC) or Aquaculture Stewardship Council (ASC) for seafood.⁹⁸ Be wary of vague or self-declared "eco-friendly" claims, which can be misleading (greenwashing).¹⁰⁷ Check company websites for sustainability reports and transparency about their practices.¹⁰⁸ Avoid single-use plastics wherever possible, opting for reusable alternatives.¹¹⁹
• Investment Choices: Individuals with savings or pensions can investigate options for investing in funds or companies that actively promote environmental sustainability and biodiversity conservation, or at least screen out those with significant negative impacts.¹³⁷

While individual choices are important drivers of change, relying solely on consumers to navigate complex global supply chains and decipher a multitude of labels is insufficient.¹⁰⁷ Making sustainable consumption the easy and default choice requires systemic support. This includes robust government policies that regulate harmful practices (like France's single-use plastic ban ¹³²), mandate corporate transparency and accountability (e.g., EU Green Claims Directive ¹⁰⁸, disclosure frameworks like TNFD ⁹⁶), and provide consumers with clear, reliable information through standardized labeling or accessible tools like eco-rating apps.¹⁰⁸ Therefore, individual consumer action should be coupled with advocacy for these broader systemic changes (Section VI.D).

B. Creating Havens: Personal and Community Habitat Creation

Individuals and communities can directly contribute to local biodiversity by creating and enhancing habitats in gardens, yards, balconies, school grounds, and public spaces.¹²⁵ Even small patches of suitable habitat can provide vital resources for wildlife, especially in fragmented urban and suburban landscapes.

• Planning and Design: Assess your space, considering factors like sunlight, soil type (e.g., clay, sandy, wet, dry), and existing features.¹³⁹ Plan for a diversity of habitat structures: include taller elements like trees and shrubs for shelter and nesting sites, lower flowering plants for pollinators, ground cover to protect soil, and potentially a water source.¹³⁹ Think about providing resources throughout the year by choosing plants that flower, fruit, or provide seeds at different times.¹³⁹ Look to local natural areas for inspiration on plant communities and layouts.¹³⁹
• Plant Selection: Prioritize planting native species – plants that have evolved in your local region.¹³⁸ Native plants are generally best adapted to local conditions and provide the most suitable food and habitat for local wildlife (insects, birds, etc.). Support local nurseries specializing in native plants.¹³⁸ Choose a variety of plant types – perennials, annuals, grasses, shrubs, trees – to create structural diversity and provide different resources.¹³⁹ Select flowers known to attract pollinators like bees and butterflies.¹⁴⁰
• Key Features for Wildlife:

• Food: Plant a variety of flowers (especially natives), berry-producing shrubs, and seed-bearing plants.¹³⁹ Avoid using pesticides, which harm beneficial insects and can enter the food chain.¹³⁸
• Water: Even a simple bird bath or a small container pond (like a sunken washing-up bowl) can provide essential drinking and bathing water for birds and insects. Larger ponds can support amphibians and dragonflies.¹³⁹ Ensure ponds have shallow edges or escape routes for animals.
• Shelter: Trees, shrubs, dense plantings, and even log piles or leaf litter provide places for wildlife to hide, rest, and overwinter.¹³⁹ Consider installing bird boxes, bat boxes, or insect hotels to provide specific nesting or hibernation sites.¹¹⁹
• Leave Areas 'Wild': Resist the urge to over-tidy. Patches of longer grass, piles of leaves or dead wood, and standing dead stems provide valuable habitat for many invertebrates and other small creatures.¹³⁹

• Community Efforts: Participating in or starting a community garden can amplify these benefits, creating larger areas of diverse habitat and fostering shared learning and stewardship.¹²⁴ Community gardens have demonstrated significant positive impacts on local pollinator populations and soil health.¹²⁵

While individual gardens or balconies might seem insignificant in isolation, their collective impact can be substantial. Creating a network of small, wildlife-friendly habitats across urban and suburban areas provides crucial stepping stones and refuges for wildlife, particularly mobile species like birds and pollinators, helping them navigate fragmented landscapes.¹²⁴ When these efforts prioritize native plants and provide a diversity of essential resources (food, water, shelter) ¹³⁹, they contribute meaningfully to conserving local biodiversity and enhancing ecological connectivity at a landscape scale.

C. Eyes on Nature: Participating in Citizen Science

Citizen Science (CS) involves the active participation of non-professional scientists (citizens) in scientific research, often focused on collecting or analyzing data.¹⁴¹ In the field of biodiversity, CS has become an invaluable tool, enabling data collection on scales far exceeding what professional researchers could achieve alone.¹⁴² It leverages the power of distributed observation and, increasingly, technology like smartphones and online platforms. A significant portion of global biodiversity occurrence data, such as that housed in the Global Biodiversity Information Facility (GBIF), now originates from CS projects.¹⁴²

Participating in CS offers multiple benefits. Scientifically, it generates vast datasets crucial for understanding species distributions, population trends, phenology shifts, and the impacts of environmental change.¹⁴¹ For participants, it provides opportunities for learning, skill development, direct engagement with nature, and contributing to meaningful scientific endeavors, which can foster environmental awareness and stewardship attitudes.¹⁴¹

Numerous platforms and projects facilitate participation:

• iNaturalist: A global platform where users upload photos or sound recordings of organisms. AI assists with identification suggestions, and the community helps verify observations, creating research-quality data on species occurrences.¹³⁴
• eBird: Focused on birds, users submit checklists of birds they see and hear during outings. This data, managed by the Cornell Lab of Ornithology, forms one of the world's largest biodiversity datasets, tracking bird distribution, abundance, and migration patterns globally.¹³³

• Zooniverse: Hosts a wide array of projects where volunteers analyze scientific data, often images or sound recordings. Examples include identifying animals in camera trap photos (e.g., Snapshot Serengeti), classifying galaxies, or transcribing historical records.¹⁴¹

• Specific Monitoring Projects: Many organizations run targeted CS projects, such as monitoring specific species (e.g., local bird counts), water quality (e.g., Freshwater Watch), or invasive species spread.¹⁴¹

Citizen science effectively democratizes the process of scientific data collection and, to some extent, analysis. By utilizing accessible technology (smartphones for apps like iNaturalist and eBird ¹³³) and online platforms (like Zooniverse ¹⁴²), it lowers the barrier to entry for public participation in research. This not only generates invaluable data for conservation science but also serves as a powerful tool for education and engagement, directly connecting people with the natural world around them and empowering them to contribute to its understanding and protection.¹⁴¹

D. Amplifying Your Voice: Effective Advocacy for Policy Change

While individual actions like sustainable consumption and habitat creation are valuable, systemic change requires supportive government policies and regulations. Effective advocacy plays a crucial role in influencing decision-makers to enact and implement strong biodiversity conservation measures.¹³⁷

Individuals can advocate effectively through several channels:

• Contacting Elected Officials: Reaching out to local, regional, and national representatives via letters, emails, or phone calls is a fundamental advocacy tool.¹⁴³ To maximize impact:

• Clearly identify yourself as a constituent.
• Be specific about the policy, bill, or issue you are addressing (e.g., funding for NBSAP implementation, strengthening protected area legislation, opposing a harmful development project).
• State clearly what action you want the official to take (e.g., support a bill, oppose an amendment, allocate funding).
• Explain why the issue is important, connecting it to local impacts on the environment, economy, health, or community well-being.
• Keep the message concise, respectful, and focused.
• Offer to be a source of information and provide contact details for follow-up. Using templates can be helpful, but personalizing the message increases its impact.¹⁴³

• Supporting Conservation Organizations: Joining, donating to, or volunteering with non-governmental organizations (NGOs) that work on biodiversity policy amplifies individual voices. These organizations often have expertise in policy analysis and advocacy campaigns.¹²⁸ Participate in their action alerts and campaigns.
• Local Engagement: Get involved in local government processes, such as planning board meetings or public consultations on development projects or park management plans. Support local conservation initiatives and land trusts.¹²⁸
• Raising Awareness: Educate your social network – friends, family, colleagues, community groups – about biodiversity issues and the importance of policy action. Sharing information and personal concerns can build broader support.¹³⁷

Businesses also have a critical role to play in policy advocacy, termed Responsible Policy Engagement (RPE).¹⁴⁵ Companies serious about their nature commitments should align their advocacy efforts with their sustainability goals. This involves proactively supporting ambitious pro-nature policies, ensuring their trade associations do not lobby against such policies (and intervening if they do), allocating advocacy spending responsibly, speaking out publicly in favor of positive measures, and transparently disclosing their advocacy activities.¹⁴⁵

Effective advocacy, whether by individuals or organizations, hinges on clarity and relevance. Simply expressing general support for biodiversity is less impactful than advocating for specific, actionable policies.¹⁴³ Furthermore, framing the issue in terms relevant to the decision-maker's priorities – such as local economic benefits, public health, climate resilience, constituent concerns, or corporate risk management – increases the likelihood of engagement and action. Connecting biodiversity protection to these broader societal and economic concerns strengthens the case for policy change.¹⁴³

E. Digital Discovery: Tools for Learning and Monitoring

A growing array of digital tools makes it easier than ever for individuals to learn about biodiversity, participate in monitoring, and access vast amounts of environmental data.

• Species Identification Apps: Mobile applications leverage AI and large databases to help users identify plants and animals they encounter.

• Merlin Bird ID: Developed by the Cornell Lab of Ornithology and powered by eBird data, Merlin helps identify birds through step-by-step questions, photo analysis (Photo ID), or real-time analysis of bird songs (Sound ID). It provides information, range maps, and allows users to keep personal life lists.¹³³
• Seek by iNaturalist: Uses image recognition technology to identify plants, animals, and fungi from photos taken with a smartphone, providing information and encouraging users to learn about local species.¹³⁴ (Note: iNaturalist itself is the platform for contributing research-grade data ¹⁴¹).

• Open Data Platforms: Several major platforms provide free and open access to global biodiversity data, empowering research, education, and conservation planning.

• Global Biodiversity Information Facility (GBIF): An international network and data infrastructure providing access to over 3 billion species occurrence records from institutions and citizen scientists worldwide.¹⁴⁶ Data is used extensively for research on biodiversity patterns, climate change impacts, invasive species, conservation assessments (e.g., IUCN Red List), and human health.¹⁴⁷ GBIF also offers tools and hosted portals for national or thematic data sharing.¹⁴⁷
• Protected Planet: The definitive source for data on protected areas and other effective area-based conservation measures (OECMs) globally, maintained by UNEP-WCMC and IUCN. It tracks progress towards global targets like GBF Target 3.⁷² (While primarily known for its reports, the underlying database is a key tool).
• USGS Biodiversity Information Serving Our Nation (BISON): Provides access to species occurrence data within the United States.¹⁴⁶ Other USGS tools include the Protected Areas Database of the U.S. (PAD-US), Species Mapper (tracking animal movements), World Terrestrial Ecosystems map, and databases on non-native species.¹⁴⁶

These digital tools represent a significant democratization of biodiversity knowledge and data. Identification apps like Merlin and Seek lower the barrier for amateurs to engage with and learn about the species around them, fostering curiosity and connection to nature.¹³³ Open data platforms like GBIF provide researchers, students, policymakers, and the public with unprecedented access to raw biodiversity information, enabling analysis and discovery beyond the confines of traditional research institutions and supporting evidence-based decision-making.¹⁴⁶ This increased accessibility facilitates broader participation in both learning about and monitoring the state of biodiversity.

VII. Conclusion: Charting a Course Towards a Nature-Positive Future

The evidence presented in this report confirms the profound scale and accelerating pace of the global biodiversity crisis. Quantitative assessments reveal alarming rates of species endangerment, dramatic population declines across vertebrate groups, and extensive alteration of terrestrial and marine ecosystems.¹ This crisis is not occurring in isolation; it is deeply interwoven with climate change, food and water security, human health, and socioeconomic equity, creating complex challenges that demand integrated solutions.⁶

In response, the global community has established ambitious policy frameworks, most notably the Kunming-Montreal Global Biodiversity Framework (GBF) and the BBNJ Agreement for the high seas.³¹ These agreements set clear targets for conservation, restoration, sustainable use, finance mobilization, and equitable participation. However, early assessments indicate a significant gap between this ambition and the current pace of implementation, particularly concerning national action plan updates and securing the necessary financial resources.³¹

Simultaneously, scientific and technological frontiers are rapidly advancing. Innovative monitoring techniques utilizing eDNA, remote sensing, and AI provide powerful new ways to track biodiversity status and threats.³⁶ Research into microbiomes is revealing vast, previously hidden dimensions of biodiversity crucial for ecosystem function ⁴⁸, while advances in genetics and resilience science underscore the importance of safeguarding genetic diversity through methods like seed banking and cryopreservation.⁵⁷

Critically, there is growing recognition that effective conservation requires a whole-of-society approach. The essential role of Indigenous Peoples and Local Communities as stewards of biodiversity, guided by traditional ecological knowledge, is increasingly acknowledged, necessitating a shift towards rights-based, collaborative conservation models.⁸⁷ The corporate sector is facing mounting pressure to assess, disclose, and reduce its impacts on nature, leading to the development of new accountability frameworks like TNFD and SBTN.⁷⁴ Furthermore, individual citizens possess significant agency through conscious consumption choices, habitat creation, participation in citizen science, and policy advocacy.⁹⁸

Success stories in species recovery and ecosystem restoration demonstrate that positive change is achievable when targeted, science-based actions are implemented with sufficient resources and collaboration.²² These beacons of hope highlight the potential for recovery if the drivers of loss are effectively addressed.

Achieving the global vision of living in harmony with nature requires transformative change – a fundamental reorganization across economic, social, and political systems.²³ This involves moving beyond incremental adjustments to tackle the underlying causes of biodiversity loss identified by IPBES, such as unsustainable production and consumption patterns, inequitable governance, and dominant economic paradigms that fail to value nature adequately.²⁸ It necessitates integrating biodiversity considerations across all sectors, reforming harmful subsidies, aligning financial flows with nature-positive outcomes, ensuring inclusive and equitable participation, and weaving together insights from diverse knowledge systems.²⁸

The path forward demands urgent, concerted action from all stakeholders. Governments must accelerate the implementation of their national biodiversity strategies, backed by adequate funding and robust monitoring. Businesses and financial institutions must embrace transparency and accountability, shifting investments towards sustainable practices. IPLCs must be empowered as key partners and leaders in conservation. Researchers must continue to advance scientific understanding and develop innovative solutions. And individuals must leverage their power as consumers, citizens, and stewards of their local environments. While the challenges are immense, the frameworks, tools, knowledge, and examples of success outlined in this report provide a foundation for charting a course towards halting and reversing biodiversity loss and securing a sustainable, nature-positive future for all.

Frequently Asked Questions About Biodiversity 🌿

Basics & Definitions

What's the difference between biodiversity and ecosystem?

Biodiversity refers specifically to the variety of living organisms (plants, animals, fungi, microorganisms) within a particular area, while an ecosystem encompasses both the living organisms AND their physical environment, including how they interact with each other. Think of biodiversity as one crucial component within the broader ecosystem structure.

How is biodiversity measured scientifically?

Scientists measure biodiversity through various methods including species richness (counting species), species evenness (distribution of individuals), genetic diversity assessments through DNA analysis, and functional diversity (measuring the range of traits or ecological roles). Newer techniques include environmental DNA (eDNA) sampling, remote sensing with satellites and drones, and AI-assisted identification systems.

What are biodiversity hotspots and why are they important?

Biodiversity hotspots are regions with exceptionally high concentrations of endemic species (found nowhere else) that are experiencing significant habitat loss. They cover just 2.5% of Earth's land surface but support over 50% of endemic plant species and 43% of endemic vertebrate species. They're critical conservation priorities because they represent irreplaceable concentrations of unique species under threat.

Current Status

How fast are we losing biodiversity compared to historical rates?

Current extinction rates are estimated to be 100-1,000 times higher than natural background rates. According to recent research, we've seen a staggering 73% decline in monitored vertebrate populations between 1970 and 2020. Scientists estimate that around 1 million animal and plant species are currently threatened with extinction, many within decades.

Are some types of organisms more threatened than others?

Yes, threat levels vary significantly across taxonomic groups. According to the IUCN Red List, particularly vulnerable groups include cycads (71% threatened), amphibians (41% threatened), reef-building corals (44% threatened), sharks and rays (37% threatened), and conifers (34% threatened). These disparities reflect different sensitivities to human pressures like habitat loss, pollution, and climate change.

Can species recover once they're endangered, or is it usually too late?

Species can absolutely recover with targeted conservation efforts! Success stories include the American Alligator, Bald Eagle, Giant Panda, Iberian Lynx, and more recently, the Saiga Antelope and Scimitar-horned Oryx. Recovery typically requires addressing specific threats through legal protection, habitat restoration, captive breeding programs, and community involvement.

Biodiversity & Human Systems

How does biodiversity loss affect the economy concretely?

Biodiversity loss directly impacts industries like agriculture (reduced pollination, pest control, soil fertility), pharmaceuticals (lost potential medicines), tourism (degraded natural attractions), fisheries (collapsed stocks), forestry (reduced timber yields), and insurance (increased natural disaster risks). Economically, sectors representing 55% of global GDP are moderately or highly dependent on biodiversity, with potential GDP losses of up to 10% annually by 2030 for vulnerable countries.

What's the connection between biodiversity and pandemic risk?

Biodiversity loss increases pandemic risk through several mechanisms. When natural habitats are destroyed, wildlife is forced into closer contact with humans and livestock, creating opportunities for pathogens to jump species (zoonotic spillover). Additionally, diversified ecosystems have a "dilution effect" where pathogens are distributed across many species rather than concentrated in a few. Recent research shows that areas with higher rates of deforestation and biodiversity loss correlate with increased emergence of novel infectious diseases.

How does protecting biodiversity help with climate change?

Biodiverse ecosystems like forests, wetlands, and grasslands sequester and store massive amounts of carbon. They also enhance resilience to climate impacts—mangroves and coral reefs buffer coastlines from storms, diverse forests resist wildfires and disease outbreaks better than monocultures, and healthy soils retain more water during droughts. Nature-based climate solutions could potentially provide up to 37% of the mitigation needed to meet Paris Agreement goals by 2030.

Action & Solutions

What can I do to support biodiversity beyond my garden or consumption habits?

Beyond personal actions, consider: participating in citizen science projects like iNaturalist or eBird; advocating for strong biodiversity policies by contacting elected officials; supporting Indigenous-led conservation initiatives; investing in biodiversity-positive financial products; volunteering for habitat restoration projects; and sharing knowledge about biodiversity with your community. The collective impact of these actions significantly amplifies your individual contribution.

How effective are protected areas at conserving biodiversity?

Well-managed protected areas are highly effective, but their success depends on several factors. They work best when they're properly funded, sufficiently large, connected to other natural areas, designed with local community input, and managed for ecological integrity rather than just designated on paper. Recent studies show protected areas managed by Indigenous peoples often show better biodiversity outcomes than conventional protected areas.

Are technological solutions like DNA banks and cloning viable backup plans for biodiversity?

While seed banks, biobanks, and genetic repositories provide crucial safeguards for genetic diversity, they're supplements to—not replacements for—protecting species in their natural habitats. They preserve genetic material but can't recreate the complex ecological relationships, evolutionary processes, and ecosystem functions of intact natural systems. De-extinction technologies remain extremely limited and resource-intensive, making conservation of existing biodiversity far more effective than trying to resurrect lost species.

Emerging Topics

How is AI changing biodiversity research and conservation?

AI is revolutionizing biodiversity conservation through automated species identification from images, sounds, and genetic samples; predictive modeling of species distributions under climate change; real-time monitoring systems for protected areas (detecting poachers, fires, illegal logging); optimizing conservation planning to maximize biodiversity protection with limited resources; and analyzing vast datasets to discover patterns invisible to human researchers.

What role do microbiomes play in biodiversity conservation?

Microbiomes—communities of bacteria, fungi, and other microorganisms—are increasingly recognized as fundamental to biodiversity at all scales. They drive nutrient cycling in soils, aid plant growth, support animal digestion, and contribute to ecosystem resilience. Conservation efforts are beginning to explicitly incorporate microbiome management, including soil inoculation during restoration, protection of environments with unique microbial diversity, and consideration of how human activities impact these invisible but essential communities.

How is the corporate world responding to biodiversity loss?

The corporate sector is increasingly addressing biodiversity through frameworks like the Taskforce on Nature-related Financial Disclosures (TNFD) and Science Based Targets Network (SBTN); integrating biodiversity into ESG reporting; investing in nature-based solutions; transitioning to regenerative supply chains; and adopting "nature positive" business strategies. Leading companies now recognize biodiversity not just as a corporate responsibility issue but as a material business risk requiring strategic management.
