Why biodiversity is an economic security issue

Biodiversity — the variety of life across genes, species and ecosystems — is not an environmental abstract reserved for scientists and conservationists. It underpins the goods, services and resilience that modern economies depend on. When biodiversity declines, the effects cascade through supply chains, public budgets, corporate balance sheets and national stability. Treating biodiversity as an economic security issue reframes it from a conservation priority to a fundamental component of national and global economic resilience.

The connection between biodiversity and economic stability

• Provisioning services and supply chains. Biodiversity supplies food, timber, medicines, fibres and genetic material. Agricultural yields, fisheries output and pharmaceutical pipelines all depend on biological diversity and ecosystem health. Interruptions or loss of these inputs directly reduce production and raise prices.
• Regulating and protective services. Healthy ecosystems moderate flood and drought risks, filter water, sequester carbon and control pests and disease vectors. The economic value of avoided damage and reduced insurance costs can be enormous.
• Resilience and innovation. Genetic diversity provides the raw material for crop and livestock breeding, pest and disease resistance, and adaptation to climate change. Less diversity means less capacity to adapt to shocks.
• Risk transmission to finance and trade. Biodiversity loss creates operational, market and systemic risks: stranded assets (e.g., degraded forestry or fisheries concessions), supply disruptions for multinational companies, and increased credit and insurance risk for banks and insurers.
• Security and social stability. Resource scarcity driven by ecosystem decline can amplify migration, local conflicts and social unrest, with national security and fiscal implications.

Essential metrics and validated insights

• Scale of economic dependence: A major assessment by the World Economic Forum estimated that more than half of global GDP — roughly US$44 trillion — is moderately or highly dependent on nature.
• State of nature: The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) warned that around one million species are threatened with extinction and that roughly 75% of the land surface has been significantly altered by human actions, with significant impacts on ecosystem services.
• Food and fisheries: Fisheries and aquaculture provide critical nutrition and livelihoods. FAO data indicate tens of millions of people are employed in primary fisheries and aquaculture, and more than three billion people rely on aquatic foods for a significant share of their animal protein.
• Pollination: Many staple and high-value crops depend on animal pollinators; the loss of pollinator services has been estimated to put hundreds of billions of dollars of crop value at risk annually.
• Pandemic-scale risks: Land-use change, wildlife trade and biodiversity loss increase the risk of zoonotic spillover. The COVID-19 pandemic imposed economic disruption measured in the trillions of dollars globally, underscoring the potential cost of failing to manage biological risks that intersect with human health.

Specific illustrations and scenarios

• Agriculture and pollinators: Intensive farming, habitat loss and pesticide use have reduced wild pollinator populations in many regions. Sectors such as fruits, nuts and oilseeds face higher production costs and price volatility when pollination services decline. Regions heavily reliant on a narrow set of crops become vulnerable to pollinator or pest shocks.
• Fisheries and coastal communities: Overfishing and habitat degradation reduce fish stocks, eroding incomes for coastal households and export earnings for nations. Declines in fish populations have forced fleet downsizing, job losses and increased pressure on alternative livelihoods.
• Wetlands and flood protection: Intact wetlands and mangroves attenuate storm surge and floods. Where these systems are removed or degraded, flood damages and reconstruction costs rise, increasing federal and municipal expenditures and insurance payouts.
• Medicines and genetic resources: Many pharmaceuticals are derived from natural products or require biological diversity for discovery pipelines. Loss of habitats narrows the pool of potential medical discoveries and can raise long-term healthcare costs.
• Historical lesson — the Irish potato famine: The potato monoculture’s lack of genetic diversity contributed to catastrophic crop failure in the mid-19th century, triggering famine, migration and widespread economic collapse in affected regions. The case illustrates how biological uniformity amplifies vulnerability.

Financial framework and corresponding policy actions

• Risk disclosure and standards: Regulators, investors and corporations are increasingly acknowledging financial risks tied to nature. The Taskforce on Nature-related Financial Disclosures (TNFD) offers a structure to evaluate and report biodiversity-related exposure, paralleling established climate disclosure approaches.
• Natural capital accounting: Bringing natural capital into national accounting systems and corporate financial statements enables policymakers and firms to incorporate ecosystem value into budgetary and investment choices. The Dasgupta Review underscored the need to embed nature within core economic decision-making.
• Subsidy reform: Numerous nations maintain agricultural, fisheries and resource-use subsidies that unintentionally intensify biodiversity decline. Redirecting these subsidies to incentivize sustainable methods can generate both environmental and fiscal benefits.
• Conservation finance and markets: Instruments such as green bonds, biodiversity offsets and payments for ecosystem services are increasingly used to attract private investment for conservation and restoration, though strong governance and safeguards remain essential to prevent unintended consequences.
• International frameworks: The global biodiversity framework adopted under the Convention on Biological Diversity establishes goals, including protecting 30% of terrestrial and marine areas by 2030, aimed at stabilizing and replenishing the natural capital that supports economic systems.

Practical steps for governments, businesses and investors

• Mainstream nature into national security and economic planning. Treat ecosystem integrity as a strategic asset in budgets, infrastructure planning and risk assessments.
• Measure and disclose exposure. Companies and financial institutions should map dependencies and impacts across supply chains and disclose nature-related risks to investors and regulators.
• Invest in restoration and nature-based defenses. Restoring wetlands, forests and mangroves can be cost-effective ways to reduce disaster risk and enhance long-term productivity.
• Support biodiversity-friendly production. Shift subsidies and procurement toward regenerative agriculture, sustainable fisheries and responsible land use to stabilize supply and prices.
• Protect genetic resources and local stewardship. Strengthen seed systems, community-based conservation and the rights of indigenous peoples, who often steward high-biodiversity landscapes.

Why timing is crucial

Biodiversity loss does not follow a predictable path, and ecological tipping points can trigger sudden, permanent shifts that unleash major economic disruptions. Taking action early typically costs far less than dealing with cascading breakdowns later on. Directing resources toward prevention, restoration and resilient stewardship reduces risk for governments, companies and households alike. The same strategic mindset used for cybersecurity, energy security and epidemic readiness must likewise be brought to the management of natural assets.

Recognizing biodiversity as a matter of economic security shifts investments in nature away from charity toward a blend of strategic risk control and opportunity generation, and the choices made today—whether to safeguard, neglect or merely repair ecosystems—will influence productive capacity, fiscal pressures, financial resilience and overall human wellbeing for generations, making the integration of biodiversity into fiscal planning, corporate oversight and international collaboration vital to ensure economies remain efficient, adaptable and secure.
