Hydropower in the Northeast: Potential and harnessing analysis - A critique
Posted on 15 Jan, 2012 11:41 PMThe main objectives of the hydropower study are as follows:
- An analysis of the hydropower potential in the Northeast and key elements of the strategy that should be followed for optimal realization of this potential
- An overview of the hydropower development options in the Northeast with regard to the water resources in the different river basins, including consideration of flood control and irrigation

Living rivers, dying rivers: Bagmati river in Nepal
Posted on 05 Jan, 2012 06:07 PMBagmati river in Kathmandu: From holy river to unthinkable flowing filth
Ajaya Dixit initiated his presentation with a general account of how rivers shape the landscape and how riverine ecosystems have nurtured society and kept civilisations vibrant, cultured and creative. Dixit went on to discuss the basin characteristics of the Bagmati, a tributary of the Kosi that rises in the Shivapuri hills, north of the Kathmandu valley. Around fifteen percent of the basin area (3700 sqkm) lies in Nepal, while the remaining is in India. The average annual rainfall in the basin is 1400 mm and is more than 2000 mm in the hills. Bagmati is a seasonal river with rainfall and springs as its main source. Its mean flow is 15.6 cubic metre/second and low flow is 0.15 cubic metre/second in April.
Kathmandu lies in the Upper Bagmati basin and studies suggest that an ancient lake called the Paleo-Kathmandu lay within the Kathmandu valley as a lacustrine formation. Early settlers lived in lower slopes and used springs and river in the upper reaches. When they moved to the valley floor, they built dongia dharas, which are stone water spouts fed by the unconfined aquifers and delivered water through surface channels. Even today, dongia dharas dated back to 1500 years exist. The state built canals (raj kulo) tapped the upper stretches of the rivers close to the mountains. Rivers and irrigation helped recharge aquifers and ponds.
However, rising urbanisation has damaged these ancient artifacts. Over the last sixty years Kathmandu has expanded massively and its population has increased from 0.41 million in 1951 to 2.6 million in 2011. The city has a huge transient population aside from this, reducing it to a concrete nightmare. Seismologists suggest that Kathmandu is a rubble city in the making. Though the Bagmati river flow has not changed significantly in the last seventy years, the character of the river has been transformed significantly during the period 1970 to 1990. The river has been canalised while the dumping of the city’s garbage into it continues. Dixit identified a plethora of problems faced by the river such as upstream water diversion for drinking water needs, disposal of untreated liquid waste, disposal of solid waste, river jacketing for roads and commercial activities, sand mining and physical encroachment.
The state of the river is an outcome of the current approach to waste management particularly liquid waste management. Three types of waste water namely yellow water flux, grey water and yellow black flux are being generated and flowing water is being used as a vehicle to dispose these. The idea of a water based disposal system e.g. flush toilet embedded in Victorian engineering has led to a technological lock-in with the result that the notion of a natural hydrological cycle has undergone a fundamental transformation.
All the same, the bulk of the load in the river is biological though there are some factories releasing effluents. In the last 20 years some of them have been closed or relocated and the river now stands a chance of being salvaged.
A plan for resolving Mullaperiyar conflict in Kerala - Forum for Policy Dialogue on Water Conflicts in India
Posted on 31 Dec, 2011 12:56 PMGuest Post: Forum for Policy Dialogue on Water Conflicts in India
The Forum for Policy Dialogue on Water Conflicts in India has been closely following the Mullaperiyar issue for the last several years. The polarisation of views around the Mullaperiyar has hardened over the years. The Tamil Nadu government insists that the Mullaperiyar dam is safe and that the water level must be maintained at the maximum level as per the agreement. The Kerala government insists that a new dam, downstream of the present dam, must be built because the present dam is unsafe. The recent tremors with their epicentres near the dam and the already diminishing trust and rising fears and apprehensions on both sides have created a grave situation needing immediate intervention and your initiative in getting the two parties together is a welcome move.
National Alliance for People s Movements condemns arrest and harassment of anti-dam protesters in Assam

On the 26 December, 2011, at 2:15 am, Assam Police in collusion with other security forces swooped down on the protesters at Ranganadi who have been blockading the Highway since December 16 and thwarting state’s attempt to carry turbines and dam materials to project site of Lower Subansiri Dam. Nearly 200 people have been arrested and earlier also security forces have been harassing the protestors. In past too, Krishak Mukti Sangram Samiti fighting against the big dams on Brahmaputra have faced government’s ire and often been attacked and jailed. NAPM stands in solidarity with KMSS and other students groups of the region who have been consistently opposed to the big dams in highly sensitive seismic zone. We condemn the sustained action and harassment of KMSS and their activists and targeting of Akhil Gogoi for constantly opposing the destructive development policies and corruption of the government machinery.
Life, livelihoods, ecosystems, culture: Entitlements and allocation of water for competing uses
Posted on 27 Dec, 2011 05:10 PMThis report has been prepared by the members of the working group set up by the Forum for Policy Dialogue on Water Conflicts in India on the issue of “Entitlements and allocations for livelihoods and ecosystem needs". The introductory chapter sets out the context of the report. The immediate context is the work of the Forum over the last 4-5 years, and the learning that this particular issue leads to many water conflicts in India.
The Mullaperiyar dam debate - An issue of safety versus rights?
Posted on 12 Dec, 2011 10:40 AMThe issue that has been making headlines in the last few days has been that of the continuing debate between the states of Kerala and Tamil Nadu over the Mullaperiyar dam. This debate has opened up a number of issues related to the ownership and use of water between the two states of Tamil Nadu and Kerala in the context of the current changes and the loss of relevance of the laws and decisions made during the colonial rule; the water sharing, irrigation and power generation needs of both the states; and the recent concerns on the safety of the dam in Kerala versus the urgent irrigation needs of the agricultural sector in Tamil Nadu.

This article sheds light on the history of the Mullaperiyar dam and the background for the current deadlock between the two states over the dam. The current deadlock between the two states over the dam is essentially not a dispute for water, but has its roots in the colonial times, and has to do with the need to come to terms with the agreements and decisions made in those times with changing economic, political and environmental contexts and concerns about the safety of the dam in Kerala versus the irrigation needs of the farmers in the state of Tamil Nadu.
