CROP PRODUCTIVITY: CLIMATE CHANGE EFFECT

Crop production can increase if irrigated areas are expanded or irrigation is intensified, but these may increase the rate of environmental degradation. Since climate change impacts on soil water balance will lead to changes of soil evaporation and plant transpiration, consequently, the crop growth period may shorten in the future impacting on water productivity. Crop yields affected by climate change are projected to be different in various areas, in some areas crop yields will increase, and for other areas it will decrease depending on the latitude of the area and irrigation application. This book provides a comprehensive review of literature related to the assessment of climate change impacts on crop productivity using climate, water and crop yield models.
