A new study published this week once again highlights not so well known impact of large dams on the rivers: role of rivers in building, supplying sediment, nutrients to floodplains, deltas, coastlines, estuaries, oceans and supporting so much biodiversity and how large dams are majorly adversely impacting this role of rivers. The study by scientists at Dartmouth using images from the NASA-US Geological Survey for 414 of the world’s largest rivers show the unprecedented changes the dams are bringing to World’s rivers, the impacts that in many cases are outweighing the impacts of climate change. This is particularly true of the northern hemisphere that includes India, World’s third largest dam builder.
Unfortunately in India, there is very little appreciation or acknowledgement of this role of rivers and how dams are affecting it. The least one can expect is that the Government of India should urgently initiate a study to document and understand this phenomena and also highlight what needs to be done about it. The study should be done by an independent team of multidisciplinary experts.

This report on World Water Day 2022 highlights the positive impacts of initiative taken by individual, communities, civil societies and government schemes towards revival and protection of water sources in India over the past one year. These efforts show how conservation, restoration and management of water resources including springs, step-wells, ponds, lakes, tanks etc. at local level are far better, cost effective and efficient solutions in comparison to big water projects which in immediate and long term cause more damages than benefits to hydrological cycle, local community, environment apart from incurring huge construction and operating costs. SANDRP has also published media compilation on positive groundwater stories and urban water options on World Water Day 2022 occasion.

What will be the realistic cost of power from hydropower projects being pushed by the Prime Minister during this visit today to Himachal Pradesh? One indication of that comes from the 111 MW Sawra Kuddu HEP that he inaugurates during his visit. The cost of this project is already over Rs 2080 Crores, likely to go up further. Which means per MW installed capacity, the cost is around Rs 20 Crores. At this cost, the cost of power from the project is likely to be over Rs 8 per unit even without factoring in the social, environmental and increased disaster vulnerability costs that such projects impose on the fragile Himalayan Mountains. As if to also remind the active seismic zone, on the eve of his visit, there were tremors, even if mild, in Mandi.
The Renuka dam that he lays the foundation for does not even have all the statutory clearances. Its EIA has been the most dishonest exercise, as came out in the NGT hearings. What signal is the government sending by laying foundation stone for such a project? Similar are the issues with Luhri I and Dhaulasidh HEPs. The government seems to be pushing such outdated, unviable, costly and destructive projects in fragile Himalayan regions, purely on political arithmetic assumptions, but possibly need to realise that these projects are not even popular and they are also most inappropriate in the climate change context. Or is it the lure of spending such huge sums of unaccountable public money that provide opportunities for getting election funds for the party that is driving such undemocratic decisions?
