Assumptions in ecosystem service assessments: Increasing transparency for conservation

Area of Science:

• Ecology
• Environmental Science
• Conservation Biology

Background:

• Ecosystem service assessments are vital for conservation efforts.
• These assessments rely on complex, multi-disciplinary methods with inherent assumptions.
• Ambiguous or inadequate assumptions can lead to misinterpretations and hinder conservation effectiveness.

Purpose of the Study:

• To synthesize and elaborate on 12 prevalent types of assumptions in ecosystem service assessments.
• To foster an interdisciplinary understanding of these assumptions within ecosystem service science.
• To improve the consistency and reliability of conservation recommendations derived from assessments.

Main Methods:

• Systematic synthesis of 12 prevalent assumption types in ecosystem service assessments.
• Elaboration on conceptual, ethical, data, mapping, modeling, valuation, and decision-making assumptions.
• Analysis of how assumptions impact assessment reliability and conservation outcomes.

Main Results:

• Identified 12 key categories of assumptions in ecosystem service assessments.
• Highlighted potential for misconceptions due to ambiguous or inadequate assumptions.
• Demonstrated the need for transparency and validation of assumptions for reliable results.

Conclusions:

• Increased transparency regarding assumptions is essential for future ecosystem service assessments.
• Testing and validating assumptions can enhance the reliability of assessment outcomes.
• Improved understanding and application of assumptions will better support conservation science, policy, and practice.
