Climate change is increasingly evident, and the design of
effective climate adaptation policies is important for regional and sectoral
economic growth. We propose different modelling approaches to quantify the
socio-economic impacts of climate change on three vulnerable countries
(Kazakhstan, Georgia, and Vietnam) and design specific adaptations. We use a
Dynamic General Equilibrium (DGE) model for Vietnam and an economy-energy-emission
(E3) model for the other two countries. Our simulations until 2050 show that
selected adaptation measures, in
particular in the agricultural sector, have positive implications for GDP. However, some adaptation measures
can even increase greenhouse gas emissions. Focusing on GDP alone can lead to
welfare-reducing policy decisions.
