Field Crops and Climate Change

Production of crops and climatic changes are internally linked with each other in several features because changes in climatic conditions are the key reason for abiotic as well as biotic stresses, that have adversative influences on the farming systems at local, regional, and global levels. The yields of major agronomic crops are being negatively impacted by climatic changes in several aspects like disparities in rainfall pattern and intensity, mean temperature, heat waves, changes in weeds infestation, disease causing microorganisms, and pest attack during all growing seasons in major cropping systems. Heat and water shortage stress disturb the crop yield in various ways as response of crop towards these impacts of climatic variables vary. Higher temperature frequently causes a reduction in crop production by reason of the fact that, they generally happen in combination with drought. Crop phenology is negatively affected due to climate change. Yield and yield components are more sensitive under drought condition in comparison to higher temperature in all cropping systems. In this chapter, we summarize the impact of climate change and stresses produced due to climate change on crop production.
