Transcript

  • 1. Water in India
  • 2. Per capita water availability in selected countries ('000 m 3 ) Water Availability (‘000 metres 3 )
  • 3. Water in India: Overview
    • India is endowed with a rich and vast diversity of water resources.
    • India has seasonal rainfall with high temporal and spatial variability.
    • 50% of precipitation falls in just 15 days and over 90% of river flows in just four months.
    • Pre twentieth century India had community level water resource management practices in place, across regions.
    • India has invested in building its water infrastructure (dams, reservoirs and canals) in arid areas.
    • The per capita water storage capacity in India is much below that of China and the US.
    • Indian rivers are in a state of decay.
    • India’s irrigation and water supply services are in poor shape.
    • Urban India heavily depends upon groundwater sources to meet the daily water requirements.
    • The total utilizable water resources of India are assessed as 1086 km 3 .
  • 4. Utilizable Surface Water and Flows Basin wise average flow and utilizable water (in km 3 /year) River Basins Average annual flow Utilizable flow Indus 73.31 46
