Rain fed agriculture provides 58 per cent of the World's food basket while accounting for 80 per cent of agricultural lands. Water for food production is becoming increasingly scarce as a result of worldwide population growth, and the situation is further exacerbated by climate change. Rain fed areas are hotspots for poverty, malnutrition, and food insecurity, as well as regions prone to extreme land degradation, water scarcity, and inadequate social and institutional infrastructure. As a result, PMKSY is regarded as an effective tool for tackling many of these issues, as well as a potential engine for agricultural growth and development in vulnerable and marginal rain-fed areas. The Pradhan Mantri Krishi Sinchayee Yojana (PMKSY) promotes water conservation in order to address the country's growing water shortage. Present paper aim is to discuss that importance of irrigation practice, Government scheme for irrigation, importance of PMKSY.
