The impact of climate change on agriculture is being witnessed all over the world, but countries like India are more vulnerable in view of the huge population dependency on agriculture. Here, Agriculture sector supports the livelihood security to more than 60% population. Notwithstanding that, the crops like rice and wheat are the staple food for Indians. Monsoons are changing more frequently. Droughts, floods, tropical cyclones, hot extremes and heat waves are negatively impacting agriculture production. Increasing glacier melt in Himalayas will affect the food production. Impact of climate is more high compared to the past which increasing global warming, natural calamities and may result fluctuations on many crops. In this study, climate change and its impact on rice and wheat crops of India has been analyzed.
