Navigating ecosystem services trade-offs: A global comprehensive review.

Area of Science:

• Environmental Science
• Ecology
• Conservation Biology

Background:

• Ecosystem services (ES) are crucial for human well-being and decision-making.
• Prioritizing certain ES over others is often necessary, leading to trade-offs.
• A comprehensive understanding of global ES trade-offs is essential for sustainable management.

Purpose of the Study:

• To synthesize global research on ecosystem service (ES) trade-offs.
• To identify patterns, biases, and research gaps across different ecosystem types and services.
• To inform future research and decision-making for equitable ES management.

Main Methods:

• Comprehensive literature review of over 3000 studies.
• Analysis of research patterns across terrestrial, marine, and freshwater ecosystems.
• Identification of biases in ES categories studied and geographical representation.

Main Results:

• Predominant focus on terrestrial ecosystems and provisioning/habitat services.
• Significant underrepresentation of cultural ES globally.
• Gaps in regulating ES research, especially in marine and freshwater contexts.
• Concentrated research in Europe, Asia, and North America; underrepresentation of Africa.
• Limited integration of multiple ES categories in studies.
• Identification of underrepresented regions requiring region-specific approaches.

Conclusions:

• Current ES research exhibits significant biases in ecosystem types, service categories, and geographical coverage.
• There is a critical need for more research on cultural ES and regulating ES in marine and freshwater systems.
• Region-specific approaches and interdisciplinary collaboration are vital for equitable ES management.
• Methodological transparency and decision-support frameworks are recommended to bridge identified research gaps.
