Deep wells and prudence - Towards pragmatic action for addressing groundwater overexploitation in India - A World Bank document (2010)
Posted on 12 Apr, 2011 01:51 AMIndia is the largest user of groundwater resources in the world. It is estimated that approximately 230 cubic kilometers per year is used annually, this is more than a quarter of the total world consumption from this resource.
It is in this context that this World Bank report looks at the reasons for this quantum of groundwater usage.
The report delves into socio-economic and political reasons and looks at policies which inadvertently promote so much extraction. The report also analyses various attempts to manage this resource. These attempts range from government and international agency efforts directed to grassroots mobilisations. Finally the report comes out with suggestions to deal with this crisis.

India’s arteries are choking. Her rivers, the lifeline of hundreds of millions, are over-taxed, polluted and encroached. They are being mined, dammed and emptied of water. Save for the four monsoon months, most rivers are streams of drains, depending on how many cities they pass through. This year people gaped in awe at the River Yamuna (I am sure they were over-awed by other rivers elsewhere too) as for the first time since 1978 looked like a river and not a drain.
Water management across space and time in India – A working paper by the University of Bonn
Posted on 17 Dec, 2010 10:09 PMThis working paper by the University of Bonn attempts to give a spatial and temporal overview of water management in India. It traces how people and the successive regimes made choices across space and time from a wide range of water control and distribution technologies. The paper divides the water management in India into four periods –
- the traditional system of water management before colonial times;
- response from the colonial rulers to manage the complex socio-ecological system;
- large scale surface water development after independence; and
- finally, the small-scale community and market-led revolution.

Posted on 18 Feb, 2008 11:15 AMMost drinking water projects are designed for supply of treated water through pipes to communities ; this requires investment on infrastructure such as pumps, overhead tanks, supply pipes, water purification equipment and after the project, maintenance staff and funds; while all this calls for planning, funding and time to execute, yet we cannot be certain that the water delivered remains uncon
