Climate change impacts on agriculture and adaptation options for Uzbekistan

Climate change is likely to reshape agriculture in an irrigated, water-scarce transition economy like Uzbekistan. We use IFPRI's International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT) model and evaluate the direct effects of climate change on Uzbekistan’s agriculture through 2050. We assume changes in GDP, population, and technological progress to be exogenous. We find that climate change and the corresponding temperature increase will have significant adverse effects on the long-term yields of cotton and wheat through changes in water availability, precipitation patterns, crop yields, and the use of land, water, and other natural resources, but harvested area responses may differ. All climate change scenarios are similar in predicting an increase in harvested area for temperate fruits and vegetables, but their yield gains remain conditional on market prices, policy reform, water use and institutional constraints. For policymakers, this makes climate change adaptation actions an opportunity for incentives and structural reforms as well as for technology to adapt to changing environmental conditions and to ensure food security.
