Biodiversity: Foundation of Economic Security

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 delivers essential resources including food, timber, medicinal compounds, fibres and genetic materials. Agricultural productivity, fisheries performance and the development of pharmaceuticals all rely on varied biological systems and robust ecosystems. When these inputs are disrupted or diminished, production falls and costs rise.
• Regulating and protective services. Functioning ecosystems help limit floods and droughts, purify water, store carbon and manage pests and disease carriers. The economic benefits from preventing damage and lowering insurance exposure can be vast.
• Resilience and innovation. Genetic variety forms the basis for improving crops and livestock, strengthening resistance to pests and diseases, and adjusting to climate change. Reduced diversity weakens the ability to cope with future shocks.
• Risk transmission to finance and trade. Declining biodiversity generates operational, market and systemic threats, such as stranded assets like damaged forestry or fisheries concessions, interruptions to supply chains for multinational companies, and heightened credit and insurance risks for financial institutions.
• Security and social stability. As ecosystems deteriorate and resources become scarcer, migration pressures, local disputes and social tensions can intensify, creating consequences for national security and public finances.

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 cultivation, shrinking habitats and the widespread application of pesticides have diminished wild pollinator numbers across numerous regions. Sectors like fruits, nuts and oilseeds often face rising production expenses and sharper price swings when pollination services falter. Areas that depend heavily on a limited range of crops become increasingly exposed to disruptions linked to pollinator declines or pest outbreaks.
• Fisheries and coastal communities: Excessive harvesting and ecosystem deterioration deplete fish stocks, undermining the earnings of coastal households and reducing national export revenues. As fish populations contract, fleets have been scaled back, employment opportunities have vanished and pressure on substitute livelihoods has intensified.
• Wetlands and flood protection: Healthy wetlands and mangrove systems buffer storm surges and mitigate flooding. When these natural barriers are cleared or degraded, flood damages escalate, leading to higher reconstruction expenses and greater financial burdens for federal and local governments as well as insurers.
• Medicines and genetic resources: A significant share of pharmaceuticals originates from natural compounds or relies on biological diversity during research and development. As habitats disappear, the range of potential medical breakthroughs narrows, which can push long-term healthcare costs upward.
• Historical lesson — the Irish potato famine: The limited genetic variability within potato monocultures played a key role in the devastating crop failures of the mid-19th century, unleashing famine, mass migration and severe economic contraction in the affected regions. This episode demonstrates how biological uniformity heightens systemic risk.

Financial system and policy responses

• 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

• Integrate nature into core national security and economic strategies. View ecosystem health as a crucial strategic resource within budgeting, infrastructure design and comprehensive risk evaluations.
• Assess and report vulnerability. Companies and financial institutions should chart their ecological dependencies and impacts throughout supply chains while communicating nature-related risks to regulators and investors.
• Channel funding into restoration and nature-based safeguards. Rehabilitating wetlands, forests and mangroves can offer cost-efficient solutions for lowering disaster exposure and boosting long-term productivity.
• Encourage biodiversity-conscious production. Redirect subsidies and purchasing policies toward regenerative farming, sustainable fisheries and responsible land management to help stabilize supplies and prices.
• Safeguard genetic resources and community stewardship. Reinforce seed systems, community-driven conservation and the rights of indigenous peoples, who frequently care for landscapes rich in biodiversity.

Why timing is crucial

Biodiversity loss is non-linear. Ecological tipping points can cause abrupt and irreversible changes that produce outsized economic shocks. Acting early is generally far less costly than addressing cascading failures later. Investments in prevention, restoration and resilient management buy down risk for governments, businesses and households. The same strategic thinking that governs cybersecurity, energy security or epidemic preparedness must be applied to natural assets.

Recognizing biodiversity as an economic security issue reframes investments in nature from charity to strategic risk management and opportunity creation. The paths chosen now—whether to protect, degrade or attempt to patch ecosystems—will shape production capacity, fiscal burdens, financial stability and human wellbeing for decades. Integrating biodiversity into fiscal policy, corporate governance and international cooperation is essential to keep economies productive, resilient and secure.
