Water in India
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 km3. www.india-reports.com
