A PES framework coupling socioeconomic and ecosystem dynamics from a sustainable development perspective.

Area of Science:

• Ecology
• Environmental Economics
• Conservation Policy

Background:

• Payments for Ecosystem Services (PES) are a growing global strategy for ecological protection and sustainable development.
• Current PES research and applications are often localized and fragmented, leading to high policy costs and suboptimal benefits.
• A unified PES framework is needed to consolidate global experiences for effective nature conservation policy implementation.

Purpose of the Study:

• To analyze global PES studies to identify research topics, spatiotemporal distributions, and compensation modes.
• To construct a unified PES framework by analyzing diverse local experiences.
• To propose a framework that couples socioeconomic and ecosystem dynamics for sustainable development.

Main Methods:

• Utilized natural language processing (NLP) to analyze 1919 global PES studies.
• Examined topics, spatiotemporal distributions, and compensation modes of ecosystem services across 114 countries.
• Synthesized findings to identify research gaps and propose a unified framework.

Main Results:

• PES research covers 80% of the world but is unevenly distributed and lacks topic diversity.
• A significant disconnection exists between PES socioeconomic strategies and natural ecosystem dynamics.
• Hotspot ecosystem services compensation modes were identified in 114 countries.

Conclusions:

• Global exchange of PES knowledge and integration with Sustainable Development Goals (SDGs) are crucial.
• A proposed PES framework couples socioeconomic and ecosystem dynamics for comprehensive management.
• This unified approach can guide future PES research and conservation strategies worldwide.
