5 SCENARIO -PRODUCTIONFood production has to increase from 247 to 494 m MT (AD 2050) to feed the ever increasing Population.Increase in cultivated area will not add much to this requirement. (Possible increase only 2 m ha from the present 143 m ha ).Converting rain-fed crops to irrigation cover (Partial or Full) is the only way out (79 to 146 m ha).
6 SCENARIO- WATERGross Water Requirement increases to 1200 BMC from the present 700 BMC.Available water remain at 1137 BMCWater deficit will force us to take extreme measures byBefore that happens conservation of water would help us survive better.Irrigation is the largest water user (+ 83%)Reducing water use in irrigation by increasing use efficiency will generate more water for irrigating more land area.
7 DRIP FERTIGATION TECHNOLOGY Drip Irrigation reduces water consumptionDrip-fertigation enhances for fertilizer use efficiency.Drip irrigation enhances yield.Productivity increase with lesser and more efficient resource useThis would be the Crux for future green revolution and food security thru water and energy security.
8 RICE STATUS Cultivated area of Rice 43.79 m ha Irrigated area 25.1 m ha (57%)Area of dry seeded rice m ha (28%)
10 WHY DRIP??DRIP Irrigation conserves water by % besides increasing productivity across crops.Drip –fertigation enhances productivity by %Lessons from several crops.
11 CHALLENGE As a country we should do things OUT OF THE ORDINARY. One who dares winsWe at Jain Irrigation have taken this challenge.Field trials were conducted in several states.

13 FOOD AND WATER SECURITY THRU DRIP "... If a minimum ten per cent (especially rainfed area) of the total paddy area of 43.5 million hectares is brought under drip irrigation, then rice output can increase to 130 million tonnes by 2020,"4.35 million ha under drip will result in irrigation water for an additional 4.8 m ha.

21 EFFORTS BY JAIN IRRIGATION Jain Irrigation has been experimenting the concept of rice cultivation thru drip irrigation.We work on our own: Experiments in Udumalpet, TN and Jalgaon, MS, farmWe work with farmers: In Rajasthan, AP, Chattisgarh, Tamil nadu, Maharashtra, Punjab.We work with universities: Tamil nadu agriculture UniversityWe work with International Institutions: IRRI,
