Kutch drought prone region: Located in western region of India, the region has unique geographical features having sea and desert. Climatologically this region is considered as semi arid region with average rainfall is 340 mm and in 5 years cycle 2-3 years would be drought years. In such harsh conditions it was necessary to focus on rain water harvesting to enhance livelihood options.

Key Objectives for focusing rain water harvesting:

  • Community awareness regarding water management – conservation & recycle.
  • Landscape restoration – Watershed & river basin management
  • Rain water harvesting – surface storage & ground water recharging
  • Improving water use efficiency specially in agriculture by discouraging flood irrigation and promoting micro irrigation

The institute has started concerted efforts to overcome the situation of water related issues and developed certain devices like check dams, percolation tanks and subsurface dykes etc for rain water harvesting and artificial recharging tube wells for recharging the ground water in many villages. This technology provides benefit to farmers by providing water for drinking as well as irrigation.

VRTI provide an artificial recharging tubewell in the reservoir of water harvesting structure constructed so that it gives duel benefit for the area. The storage area of each structure is limited. During a good monsoon shower the reservoir fills and the surplus water flow waste to the sea. When this recharging tubewell is provided in the reservoir, it will percolate the impounded flood to the groundwater table and receive further runoff which is calculated even three times to five times on its storage capacity. This technology found the best in the prevailing condition of this district.

WATERSHED MANAGEMENT PROGRAMME:

With experience in rain water harvesting in different regions, the institute has focused to work with ridge to valley watershed approach – a catchment area. 84 villages have been covered under watershed programme.

Impact of Activities:
  • Community having sense of ownership for managing water resources of the region
  • Water storage through Check dam/tank renovation (100,000 Million Liter)
  • Better use of water resource – water saving - Drip irrigation in 3,500 Ha, water saving 11,375 million liter per year
  • Drinking water availability – quality water for 1 million people
  • Prevention of salinity ingress in coastal aquifer – 20 villages( 40,000 Ha)
  • Increase in quality and quantity of water
  • Increase in irrigated land- more agriculture- more income
  • Efficient use of existing, empty and unused wells
  • Increase in greenery of the area
  • Divergence of runoff rainwater into existing water bodies, in dug wells or other created structures.
  • Increased food security
