When optimization for governing human-environment tipping elements is neither sustainable nor safe

Area of Science:

• Environmental Science
• Ecological Economics
• Policy Analysis

Background:

• Environmental governance often prioritizes economic welfare, leading to short-term gains but long-term environmental damage.
• Sustainability and safe operating space concepts offer alternative policy frameworks but lack formal comparison with economic optimization.
• Policymakers require clarity on the interrelationships between these governance paradigms.

Purpose of the Study:

• To formally compare economic optimization, sustainability, and safe operating space paradigms in environmental governance.
• To understand the trade-offs and interrelationships between these three policy approaches.
• To provide heuristics for policymakers governing complex human-environment systems.

Main Methods:

• Development of a stylized model of human-environment tipping elements.
• Analysis of policy paradigm interactions within the model.
• Derivation of conditions leading to trade-offs between paradigms.

Main Results:

• No single policy paradigm guarantees the requirements of another.
• Identified heuristics reveal conditions under which trade-offs emerge.
• Economic optimization may fail to ensure sustainability or safety in tipping systems.

Conclusions:

• The absence of a universal 'master paradigm' is critical for governing tipping systems like climate and fisheries.
• Policymakers must consider the specific parameter regime of environmental systems to select appropriate governance strategies.
• Understanding paradigm trade-offs is essential for avoiding irreversible environmental degradation.
