Environmental flows for Indian rivers:Need for a discussion to consider the health of the riverine ecosystems

India is facing a water crisis in nearly all the sectors. Fortunately or unfortunately, measures taken by the related authorities to combat the crisis often depends on the amount of 'noise' made by the relevant stakeholders. It is no wonder then, that the urban India, and especially the rich and the powerful in urban India, seldom have to face problems related to water scarcity, water quality or the sheer inequity in distribution. On the other hand, weaker the stakeholder, more severe are his ( rather 'her') problems. Marginal farmers, tail enders in a canal network, rural and urban poor, especially children and women, stand testimony to this situation. We all agree to this, right?

Godavari delta, destruction of mangroves 

But aren't we forgetting the the weakest, and in some ways, the strongest, of all the stakeholders? How about the ecosystem of the river itself?? Are we ready to acknowledge the ecosystem as an equal stakeholder in the fight for water? Are we ready to rethink the current water allocation scenario and allocate water for the riverine ecosystem and for the subsystems that depend on the river? Are we ready to accept the fact that water going to the sea is not a waste.. it is how a river should be... Current situation shows that we are evidently not ready for anything of this sort.. Let us look at some examples. In case of river Krishna, historically( before 1960s), the outfalls to the ocean averaged 57 BCM ( Billion cubic meters). In the year 2004, the outfall was nearly nil

The Ganga River Dolphin: endemic and endangered 

One of the most disturbing situation is in the supposedly water surplus Ganga Basin. According to WWF's Top Ten Rivers At Risk Report, (By the way, two of the threatened Top Ten Rivers flow through India, the Ganges and the Indus), over-extraction for agriculture in the Ganga Basin has caused the reduction in surface water resources. This has increased dependence on ground water, the loss of water-based livelihoods, and the destruction of habitat for 109 fish species, and other aquatic and amphibian fauna. Lowering water levels have indirectly led to deficiencies in soil organic content, and reduced agricultural productivity. Wetlands are also being driven to the verge of near extinction in urban as well as rural India. During the last ten years, India has lost about 38 per cent of its inland wetlands; in some districts, as much as 88 per cent of the wetlands have disappeared. Most of the wetlands and urban waterways are being used as landfills or dumping grounds for urban/ rural sewage. Ramsar wetlands also have to face similar fates.

Painted Storks at Keoladeo Sanctuary

Keoladeo National Park at Bharatpur is losing its tourists and is also about to lose its recognition as a World Heritage site because of the declining water availability and resultant declining water fowl populations. The most crucial and worrying aspect of this impasse is that political leaders have instigated the local farmers to stage demonstrations and protests against releasing waters to the Park. As a result, for the past two years, the Park has been literally starved of water and the number of migratory birds visiting the Park has fallen dangerously. This pitting of communities against ecosystems on which they depend on is criminal.

Policy Responses:

What's happening around the world?

'may, in principle, be maintained in a reasonable state even with limited environmental flows allocations (10-20% of the MAR) depending on hydrological availability.
