  1. Centre for Science and Environment, New Delhi WATER SCENARIO IN JHARKHAND Centre for Science and Environment New Delhi

  2. Area – 79,714 sq km Population - 26.9 million (Growth rate is 23.19 per cent) Urban - 5.9 million (21 percent) 152 towns 39,386 average population Rural - 20.9 million (79 per cent) 32,615 villages 642 average population JHARKHAND: AT A GLANCE

  3. WATER RESOURCES • Annual average rainfall 1400 mm • Water harvesting potential = 112 TMC(Area x amount of rainfall = volume of water received)

  4. WATER RESOURCES • 16 river basins • Total replenishable groundwater resources in 1998 was 0.660 million hectares metres per year • Provision for domestic, industrial and other uses - 0.099 mhm/year • Available groundwater resource for irrigation - 0.561mhm/year (net) • Groundwater extraction - 0.121 mhm/year (net draft) • Balance Ground Water Resources for Future Use in net terms - 0.439 mhm/year

  5. WATER RESOURCES • Fresh water sources • Ponds and tanks – 29,335 (30300.07 hectares) • Reservoirs – 106 (107351 ha) • Low lying areas – 1038 ha • Traditional water harvesting systems - Ahar INFERENCE: WATER IN ABUNDANCE

  6. REALITY?

  7. WATERPROBLEMS!! • 90 – 95 per cent of the rainfall is wasted as untapped runoff • Depleting groundwater • 22 districts – the entire state were affected by drought in 2002 • Floods affected 150,000 lives • 113 blocks of 13 districts - drought conditions prevailed in 2003 • Surface and groundwater contamination (biological, heavy metals – fluoride, manganese, nickel and sulphate)

  8. 100 mm of rain captured on 1 hectare of land gives you, believe it or not, one million litres of water. 1400 mm of rain on 1 hectare 14 million litres of water Jharkhand = 1400 mm rainfall in 79,714 sq km = 112 TMC (50 per cent being harvested 56 TMC or 56000000000000 litres Urban = 12.28 TMC ; Rural = 43.5 TMC RAINWATER HARVESTING POTENTIAL
