Profile study of rainwater retaining capacity in Mirzapur district, UP

Water is the key input in crop production and essential to all life¿human and animal. Agriculture and several of the other economic activities in sub-tropical to dry areas depend on rain. Harvesting and recycling of rain-water in dry lands are important in order to improve water use efficiency. However, about 80% of the world¿s agricultural land is rainfed, contributing to at least two-thirds of global food production. The rainfed areas currently account for about 60% of world food production. Farmers¿ yields in rainfed regions in the developing countries are low largely due to low rainwater use efficiency.
