Climatic factors such as rainfall and temperature are the most important elements that determine the productivity of crops. Proper analysis of rainfall trend and understanding its relationship with the land productivity is believed to help the proper planning of agricultural management ventures. With the current climate change threat slight variabilities in the availability of rainfall can lead to a significant impact on crop yields. Hence, supplementing rainfed agriculture with irrigation and efficient management of ecosystems are the prominent gateways to combat food insecurity.
