Potential impacts of future climate changes on agriculture

Climatic change impacts on agriculture, livestock and human health are being witnessed all around the world. The agricultural sector is a driving force in the gas emissions and land use effects thought to cause climate change. The agricultural food system is responsible for a significant amount of greenhouse gas emissions. Food availability is the most important issue that takes the priority places in the policies of all countries all over the world. The climatic change could affect agriculture in several ways; among these ways are productivity (in terms of quantity and quality of crops); agricultural practices (through changes of water use and agricultural inputs such as herbicides, insecticides and fertilizers). Moreover, climate change could affect food security, insects, plant diseases and weeds as global warming could lead to an increase in pest insect populations, harming yields of crops like wheat, soybeans, and corn. While warmer temperatures create longer growing seasons, and faster growth rates for plants, it also increases the metabolic rate and number of breeding cycles of insect populations.
