The economics of biodiversity loss: Implications for Asia and the Pacific

• Biodiversity loss is a first-order economic risk, as it erodes the natural inputs essential for economic production and increases vulnerability to systemic shocks.
• The economic impact of ecosystem degradation in Asia and the Pacific is significant, creating new risk profiles for governments and global investors.
• Mitigating these risks requires integrating ecological health into financial decision-making and implementing targeted conservation mechanisms.

Ecosystem Services and Economic Production

• Ecosystem functions—such as pollination, water purification, and carbon storage—act as essential factors of production that complement labor, land, and capital.
• These functions are complements, meaning the loss of one cannot easily be offset by improvements in others.
• As biodiversity declines, ecosystems become more fragile; the marginal importance of each remaining species increases, making the overall system prone to abrupt failures.

Regional Evidence and Risks

• India's vulture collapse (1990s): The loss of scavengers caused a natural sanitation crisis, resulting in an estimated 100,000 additional human deaths annually and $70 billion in economic losses.
• Coral Triangle: Marine degradation in Southeast Asia threatens the livelihoods of over 100 million people, with losses estimated at $38.3 billion over the last two decades.
• Exposure patterns: While countries like Malaysia and Indonesia face severe aggregate loss, economies like Singapore face high risk due to specific functional imbalances in their ecosystem services.

Financial and Policy Instruments

• Biodiversity bonds: Institutions like the ADB are raising capital for nature-positive projects, such as the October 2024 issuance purchased by Daiichi Life Insurance.
• Debt-for-nature swaps: Financial restructuring deals, such as the July 2024 U.S.-Indonesia agreement, redirect debt obligations toward regional conservation efforts.
• Market-based incentives: The European Commission is developing "nature credits" to provide targeted payments to farmers for ecosystem protection.
• Regulatory oversight: The Monetary Authority of Singapore has set standards requiring financial institutions to assess biodiversity risks alongside climate risks.

Policy Implications

• Unlike carbon emissions, the value of biodiversity is highly localized; policies must account for regional variations in ecosystem fragility and specific species roles.
• Conservation strategies should prioritize ecosystems where a few remaining species perform essential, irreplaceable functions.
• Protecting nature is an investment in long-term economic resilience and must be treated as a core financial strategy rather than a secondary environmental goal.
