Synopsis Live storage at present constitutes only 10 per cent of the total water potential of the country. Hand in hand technology development in drilling and pumping methods has paved the way for massive exploitation of groundwater mainly for irrigation (85 per cent) and for industry and domestic purposes (15 per cent). Such a localized over drawl of ground water has to be compensated adequately by harnessing surplus monsoonal flows along with expansion of water storage capacities in enhancing the water availability. Stress would need to be laid on conjunctive use of surface and ground water in irrigated commands. Tube wells and wells are the major sources of irrigation in our country. About 30 per cent of the electricity is consumed in pumping water. Operational efficiency of the pump sets is also as low as 30-33 per cent. In diesel pump set, it is about 13 per cent only. IS pumps should therefore be used and the worn out pats be replaced. Use of PVC pipes in place of conventional GI would also help in reduction of friction losses thereby the pumping cost. Canal irrigation systems generally are about 40 per cent efficient resulting in wastage of water and thereby low irrigation efficiencies. On-farm development work to avoid loss of water is therefore critically important. This book contains useful information on “Command Area Development and Management” from the selected technical papers presented during the 37th and 38th ISAE Annual Convention and symposium held at CTAE, MPUAT, Udaipur from Jan 29-31, 2003 and CAET, Dr. B.S. Konkan Krishi Vidyapeeth, Dapoli from Jan 16-18, 2004, respectively.
