Singh, A.K. | Gautam, R.C. (Indian Agricultural Research Institute, New Delhi (India))
In irrigated as well as in rainfed areas, it is essential to work on the increase in water/ moisture-use efficiency of the crops. Since water is precious, suitable methods of irrigation and in-situ moisture conservation practices are to be adopted by the farmers on the basis of the suggestions made by the agricultural scientists of the country. In rainfed areas, suitable tillage can play a significant role in the conservation of moisture. Selection of crops and their varieties, fertilizer management and proper methods of sowing are the factors for increasing the moisture-use-efficiency and productivity. Methods of irrigations are to be modified in irrigated areas mainly to check the unnecessary loss of water.

Samra, J.S. | Sharma, B.R. (Indian Council of Agricultural Research, Krishi Bhavan, New Delhi (India))
The current financial crisis of irrigation sector is attributable to and characterized by inadequate budgetary allocations, low irrigation water rates and their poor recovery, inadequate maintenance of irrigation works, meagre financial resources available for organization and management, highly subsidized electricity for irrigation pumping and absence of any groundwater extraction charges and regulation policies. The 'business as usual' scenario of the irrigation sector, if allowed to continue, will add to the already severe financial crisis and make the perceived investments financially unviable and unsustainable. Sustaining the huge investment envisaged for the irrigation sector would require moving towards an "improved management" scenario.
