climate change adaptation planning in Thailand has focused primarily on minimizing the impacts of future climate change. The resulting preoccupation with the uncertainty of climate change predictions has hindered the implementation of adaptation policies. A paradigm shift towards mainstreaming climate change into development planning (including water-related plans), and away from addressing adaptation separately from development, can reduce the inaction of policymakers. This document proposes a framework for mainstreaming climate change into community development plans (e.g., water resource development plans), and presents a case study of the Lao-oi district in Thailand.
