With the growing threat of food insecurity and a largely erratic rainfall pattern, Kerala, despite its very high rate of annual precipitation, has embarked on a series of large budget irrigation schemes. However, with the shift in acreage in favour of certain cash crops which demand relatively less moisture, the requirement of water in agriculture may change. This paper finds, after estimating the total water required for irrigation purposes in Kerala, that the state government need not pump a huge amount of funds into major irrigation projects.
