tIncreased risk due to global warming has already become embedded in agricultural decision making inCentral Asia and uncertainties are projected to increase even further. Agro-ecology and economies ofCentral Asia are heterogenous and very little is known about the impact of climate change at the sub-national levels. The bio-economic farm model (BEFM) is used for ex ante assessment of climate changeimpacts at sub-national levels in Central Asia. The BEFM is calibrated to 10 farming systems in CentralAsia based on the household survey and crop growth experiment data. The production uncertainties andthe adaptation options of agricultural producers to changing environments are considered paramount inthe simulations.Very large differences in climate change impacts across the studied farming systems are found. Thepositive income gains in large-scale commercial farms in the northern regions of Kazakhstan and negativeimpact in small-scale farms in arid zones of Tajikistan are likely to happen. Producers in Kyrgyzstanmay expect higher revenues but also higher income volatilities in the future. Agricultural producers inUzbekistan may benefit in the near future but may lose their income in the distant future. The negativeimpacts could be further aggravated in arid zones of Central Asia if irrigation water availability declinedue to climate change and water demand increase in upstream regions. The scenario simulations showthat market liberalization and improved commodity exchange between the countries have very goodpotential to cope with the negative consequences of climate change.
