Irrigation and Melioration


Agricultural production is highly vulnerable to climate shocks and predicted climate consequences may pose severe challenges to the resilience of Uzbek agricultural system, especially in terms of food security and income stability of rural producers. In this context, present study proposed to assess the impact of climate factors, such particular changes in mean temperature and rainfalls on total output of wheat-cultivating farmers in Samarkand region. By considering irrigation source and heterogeneous geography of the region, farmers engaged in wheat production were analyzed in two: upstream and downstream zones using Fixed effect panel approach. The empirical findings of study revealed that, the impact of climate factors differs across the region, while 1% increase in mean temperature during the months of (March-June/flowering period) was found to have negatively significant effect, while caused perceptible losses on total yield of wheat-cultivating farmers followed by 10% and 2% in downstream and upstream areas of Samarkand region. Contrary, precipitation had positive and significant effect on production of farmers operating in both areas of the region.
