Research on Climate Change Issues

Agriculture plays important role in human welfare. An extensive research has been carried out on agriculture and changes in climate over the past decades. Variation in climate is anticipated to influence livestock and crop production, hydrologic balances, input supplies, and other constituents of agricultural systems. It is likely to have significant effect on food security in the upcoming decades, by decreasing food production and enhancing food prices. Food may become more exclusive as climate variation mitigation struggles increase energy prices. Water essential for food production may become rarer due to enhanced crop water use and dry period. Struggle for land may enhance as definite regions become climatically unsuitable for production. Though stable increases in carbon dioxide and temperature may outcome in more satisfactory conditions that could enhance the production of some crops, but in some areas, these latent production increases are likely to be limited by severe events, particularly extreme drought and heat, during flowering phase. Crop production is probably to reduce in many regions during the twenty first century due to climatic variations.
