Abstract: Climate change is posing a serious threat to humanity, as the world’s population grows the demand for food and water will also increase. The rise in global surface temperatures is a big challenge for Food security. The rise in temperature will cause water shortage. Haryana is primarily an Agriculture state and stands second at food production in India. Climate change in Haryana will lead to reduced crop yield henceforth a threat to Nations food basket. Rise in temperature will impact all the crops, for every degree rise in temperature there is a significant decline in the yield of Wheat. A reduced rainfall will impact both Kharif (Summer) and Rabi (Winter) crops. The rise in Global surface temperature is primarily due to the release of Green house gases to the atmosphere. Rapid Industrialization and increase in population is laying stress on our resources.
