  1. HEADS UPONWATER CONSERVATION IN AGRICULTURE S MAKHIJA STRATEGIC ADVISOR JAIN IRRIGATION SYSTEMS LTD.

  2. WATER RESOURCES OF THE WORLD Total Water : 1,400 million km3 Fresh Water : 2.53% (35 million km3)

  3. With 2085 cubic km of fresh water India stands 7th in the world. • India heading towards water scarce situation Source: Biswaas, A.K. 1998. Water Resources-Environmental Planning, Management and Development. Pub: Tata McGraw-Hill Publishing Company Limited , NewDelhi

  4. VALUE OF WATER Paddy requires approx. 120-180 cm of water If water is priced at 1 paisa a liter, it costs Rs. 1,20,000 -1,80,000 for growing paddy in one hectare land

  5. SCENARIO OF IRRIGATED AGRICULTURE

  6. TECHNOLOGIES FOR ON-FARM WATER CONSERVATION • Enhanced Storage by on farm Rain water harvesting • Soil Conditioning to increase Soil water holding capacity • Mulching to reduce soil evaporation losses • Developing crop varieties with high water use efficiency- Genetic engineering • Recapturing and storing of water from water logged areas using sub soil drainage pipes • Replacing open canals with Piped conveyance • Adopting water conserving irrigation methods like drip or sprinkler. • Irrigation scheduling based on Crop- Soil-Climate relationships • Increasing precision of irrigation by use of moisture sensors and timing devices

  7. 1. AUGUMENTING WATER RESOURCES INTEGRATED WATER SHED AND WATER HARVESTING

  8. 2. UTILIZATION OF WATER RESOURCES THRU MICRO IRRIGATION

  9. Micro Irrigation - Technology for Sustainable Agriculture

  10. HOW PRECISE IS IRRIGATION?? • Crop water requirement • Crop root characteristics • Soil texture • Soil-Plant-water relationship

  11. MICRO IRRIGATION- Benefits to Grower** ** NCPA 1990 * Number of fruits

  12. WATER SAVING

  13. EFFICIENCY OF DIFFERENT TYPES OF IRRIGATION 100 90% - 95% 90 80 70% - 85% 70 60 50% - 70% Efficiency 50 40% - 50% 40 30 20 10 Flood Furrow Sprinkler Drip Key Point : Better efficiency of the irrigation potential created through irrigation Projects.

  14. PRODUCTIVITY IN RESEARCH TRIALS UDUMALPET, JAIN R&D FARM TAMIL NADU

  15. YIELD OF RICE UNDER DRIP FROM DIFFERENT STATES

  16. IMPROVEMENT IN WUE

  17. INVESTMENT IN MICRO IRRIGATION TECHNOLOGY

  18. WHERE DO WE STAND ? Subsidy allocation rose by mere 5.6% over 2010-11. 26 % 5.6 % 108% 11.6% - 0.4% A mere growth of 1-2 % over 2009-10 in acreage of Micro irrigation adoption

  19. POTENTIAL IMPACT OF MICRO IRRIGATION DURING XII PLAN Apart from the above, there will be huge employment generation in rural areas.
