Abstract
Climate is the primary determinant of agricultural productivity and climate change is expected to influence crop and livestock production; hydrologic balance; input supply; type, frequency and intensity of pests and diseases; availability and timing of irrigation water application; severity of soil erosion etc. However, nature of these biophysical effects and human responses to them are complex and uncertain. Crop and livestock yields are directly affected by changes in climatic factors like temperature and precipitation and extreme events viz. droughts, floods, and wind storms. Additionally, carbon dioxide is fundamental for plant production; rising concentrations have the potential to enhance productivity of agro-ecosystems. Given the fundamental role of agriculture in human welfare, concerns have been expressed by federal agencies and others regarding the potential effects of climate change on agricultural productivity. Interests in this issue have motivated a substantial body of research on climate change and agriculture over the past decade.
