Integrating Ecological and Economic Approaches for Ecosystem Services and Biodiversity Conservation: Challenges and Opportunities

This narrative review examines how ecological and economic perspectives can be integrated to support ecosystem services management and biodiversity conservation. We synthesize core valuation approaches (accounting-based exchange values versus welfare-based measures), discuss their appropriate uses and limitations, and illustrate implications through selected cases in watershed protection, protected areas, and forest carbon. We then review design features of Payments for Ecosystem Services (PES) with attention to additionality, leakage, and equity, and distill lessons for policy mixes that combine market-based instruments with regulatory and informational tools. Finally, we outline opportunities and risks in applying artificial intelligence to ecological–economic analysis, emphasizing accuracy–energy trade-offs and responsible data practices. Across topics, we prioritize mechanism-focused interpretation, triangulate findings from representative studies, and highlight decision-relevant takeaways rather than comprehensive coverage. We conclude with practical recommendations for analysts and policymakers: align valuation method with decision context; pair PES with targeting and monitoring; embed price-based instruments in adaptive policy mixes; and adopt transparent, efficiency-aware analytic workflows—especially when using computationally intensive methods.
