Water Management — Water Use in Rainfed Regions of India
Large investments of about Rs.800 billion since Independence has gone into development of surface irrigation projects and the gross irrigated area increased from 22.56 m ha to 75.14 m ha by 2000-01 in India. In spite of large-scale developments in irrigation sector, the agricultural production remains static at 212 mt, a cause of great concern, which is mainly attributed to the inefficient water management practices, poor maintenance of structures and water conveyance systems. In this review article, various issues, perspectives and strategies in water management research programs were highlighted. The impact of climate change on water resources at global level and at national level has also been discussed. A few case studies on improving the water use efficiencies through watershed programs carried out at CRIDA, Hyderabad are mentioned. Social problems in implementing water management strategies have been indicated.
