ABSTRACT: Climate change is projected to have a significant impact on temperature and precipitation profiles, which in turn poses a major challenge for global food security via, changes in population growth, income dealing out, nutrient choice, disease tendency, expanded trade for land water resources for urban development and rates of improvement in agricultural productivity. The responsiveness of yields will depend partly on the crops themselves, including any genetic improvements made to reduce sensitivity to temperature or improve responsiveness to CO2, as well as flexible administration adjustment by farmers in selecting what, when, where, and how to grow their crops. The profit of wheat and soybeans could increase by 30% or more under a doubling of CO2 concentrations whereas, maize presentation a much smaller response (less than 10% increase). Still, a few aspects be allowed prevent these possible increases in yield. Example if temperature is superior to a crop’s optimum level or if adequate water and nutrients are not available, yield increases may be reduced or inverted. An increase of 2 degrees centigrade over normal during flowering will reduce the yield of wheat by 15-20%. An increase in 1 degree centigrade at night can reduce the yield of rice by 10%. India’s average temperature is supposed to rise by at least 1 degree centigrade by 2050.
