Geographically, Rajasthan does not have very favourable conditions. Annual average rainfall is the minimum and there is a dearth of the perennial rivers and the Western Rajasthan is desert and is prone to drought and famine for years together. Underground water resources have either no water or very limited quantity of water. About 90% population of Rajasthan depends upon ground water resources and about 60-70% water used for agriculture comes from ground resources. Reckless exploitation of water for years together has emptied the reserves of water.
