  1. Jal Shakti Abhiyan Best Practices … by in Tiruvannamalai District Tamil Nadu K.S.Kandasamy, District Collector.

  2. Water Stressed Villages

  3. Annual Rainfall

  4. Rain fall & Ground Water Level

  5. Innovative Interventions

  6. Water Bank • Registered under TN societies Registration Act formed under the chairmanship of District Collector • Officials, NGO’s, volunteers and farmers are members • An effort to converge schemes like MGNREGA with CSR , Donors to rejuvenate the water bodies by involving the local volunteers • Hereby we are extending material and labour support to the volunteers • There are 113 voluntary groups registered and renovated 327 water bodies in last 2 months

  7. Dedicated Office

  8. Field Activities

  9. “Auto Off Switch” for OHT water pumps • To avoid wastage of water in community overhead tanks located in remote areas, automatic cut off switches have been installed • Pump turn off once tank is filled and when borewell dried • It has twin benefits of saving water and improving the motor life

  10. Equipments

  11. Mulching • Mulching is a cultivation technique of covering the soil with biodegradable plastic sheet around root zone to generate conducive soil condition • The plants are irrigated by drip irrigation under this method • Banana, Water Melon, Musk Melon, Papaya and Brinjal are most suitable crops • This saves 30 to 40% water against conventional irrigation method • It also controls weed, improves yield by 20% and advances harvest time • Now 75 Hectares under mulching cultivation in the District

  12. Field Papaya Musk Milan

  13. Field Tapiocoa Banana

  14. Pot Irrigation • A traditional technique for watering the plants • A clay pot is earthed close to root zone of plants • A small hole is made at the bottom of the pot towards roots and a coir thread is inserted through which water let off to root • 35,000 saplings are being planted using pot irrigation • This method helps in daily watering to once in 4 days

  15. Field

  16. Micro Irrigation • Drip irrigation, rain gun, sprinklers and rain hose are extensively used • Farmers are supported under the PradhanMantriKrishiSinchayeeYojana • Drip irrigation now used in sub soil level which helps less water usage and also fertigated at root • Extensively used for sugarcane crop and saving more than 50% of the water • Sprinklers and Rain guns will save more than 60% of the water • Rain Hose Irrigation more suitable for flowering plants and control insect population in the field • 16,820 Hectares of land have been brought under Micro Irrigation in the last three years in the district

  17. Rain Hose Drip Irrigation

  18. Rain Gun Drip Irrigation Rain Gun Drip Irrigation Sprinkler

  19. Water Budget • Is prepared for all the villages by taking water demand and supply • Ground water data and surface water taken and compared with water requirement for various crops in the village • Water gap is derived and with the help of 3D contour map various water saving and harvesting techniques are planned for each village • Water Conservation and watershed Developmental measures are suggested to bridge the gap between the demand and supply

  20. Water Budget

  21. Village -3D – Contour Map

  22. Crop Diversion • Farmers are used to cultivate paddy and sugarcane in assured irrigated areas • Paddy and Sugarcane requires 12000 KL and 16500 KL of water per hectare respectively from sowing to harvest • Thereby farmers are able to rise one crop a year then land fallowed for rest of the period • By intensive persuasion around 5000 hectares which are usually under paddy and sugar cane are diverted into less water intensive crops like Groundnut, Black gram and Green gram • These crops require on an average 7340 KL of water per hectare now farmers are able to rise two crops in a year

  23. Mass Awareness

  24. Activity by school children

  25. Balloon

  26. Display Board

  27. JSA Interventional Outcome Immediate visible Outcome • More awareness among the public to save rain water • Reduction in wastage of water at community • More public participation in maintaining water bodies and recharging ground water • More fallow land are brought under cultivation • Increase in water holding capacity in water bodies • Increase in soil moisture

  28. JSA Interventional Outcome • Productivity will be more (Rice 7.04L MT) • Aggressive technology & Machinery application in agricultural practices by farmers • Shifted 5000 Hectares from single crop to double crop • Increase in income to farmers • More green on earth will be seen Assured Future Outcome

  29. Thank you
