Improving the representation of adaptation in climate change impact models

Area of Science:

• Environmental science
• Climate change research
• Human-environment interactions

Background:

• Climate change adaptation is a critical human process influenced by uncertainties.
• Existing assessment models struggle to capture the complexities of adaptation.
• A lack of systematic descriptions hinders the improvement of adaptation models.

Purpose of the Study:

• To review scientific literature on climate change adaptation conceptualizations and models.
• To investigate methods for improving the representation of adaptation in models.
• To identify gaps in current modeling approaches.

Main Methods:

• Systematic literature review of scientific publications on climate change adaptation.
• Analysis of adaptation dimensions (intent, timescale, spatial scale, etc.).
• Evaluation of how different modeling approaches represent adaptation.

Main Results:

• Real-world adaptation varies across multiple dimensions not well-covered by current models.
• Models often represent adaptation artificially, neglecting human decisions, triggers, and constraints.
• Existing modeling approaches are isolated and lack unified representations of adaptation.

Conclusions:

• Current models offer a limited and often unrealistic view of climate change adaptation.
• Future model development should integrate human decision-making and contextual factors.
• Enhanced models can improve understanding of adaptation processes and effectiveness.
