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

Environment Statistics – A compendium by the Ministry of Statistics and Programme Implementation (2011)
Posted on 07 Jan, 2012 04:25 PMIt broadly covers five core parameters, viz., biodiversity, atmosphere, land/soil, water and human settlements suggested by the Framework for Development of Environment Statistics (FDES) published by United Nations Statistics Division (UNSD) in 1984.
A survey of point of use household water treatment options for rural south India: A report detailing resources available
Posted on 07 Jan, 2012 10:59 AMPoint of use household water treatment is the process of treating water at the household level to improve its microbiological purity. In cases where treated municipal water is not available, or is subject to recontamination due to a faulty distribution system, household water treatment is essential and allows families control over their drinking water.
Big dams and protests in India: A study of Hirakud dam – An article in EPW
Posted on 06 Jan, 2012 12:29 PMIt is evident that the domestic resistance to the project was variously compromised by nationalist rhetoric, imperatives of state development and absence of transnational support. The Hirakud dam project has failed on all of its objectives – flood management, hydropower production, irrigation and navigation. Its socio-economic impact has been devastating.
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.
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.
Fishery statistics – A manual by Ministry of Statistics and Programme Implementation
Posted on 11 Dec, 2011 10:08 AMIt has a ready to use reference guide on methodological aspects of data (metadata) based on harmonized concepts and methodologies that facilitate international comparison and help in aggregation of statistics to derive meaningful conclusions. The adoption of the methodology suggested in this manual will go a long way in facilitating data aggregation and data comparison both at intra-regional levels, including international levels.
The section on both marine and inland fisheries consists of four chapters and appendices. Chapter I highlights the significance of the sector, need for statistical standards and development of statistical system of the sector. Concepts and definitions are placed in Chapter II. Chapter III presents sources of data and details of methodology being adopted for generating these data. Chapter IV conveys the suggestion for ensuring quality standards. Lastly, appendices include estimation methods, forms and schedules and major resources available in the Indian waters.
Trouble in Tigerland: Why conservation efforts continue to fail
Posted on 30 Nov, 2011 11:53 AMGuest Post: Nitin Rai, Ashoka Trust for Research in Ecology and the Environment (ATREE)
Drawing upon his experience working with the Soligas who live within the Biligiri Rangaswamy Temple Wildlife Sanctuary, Nitin Rai talks about the ‘wilderness’ myth and explores the origins and impacts of the belief that people and animals cannot co-exist.
Bringing life back to Chilika lagoon in India

This 116,500 hectare brackish lagoon separated from the Bay of Bengal by a long sandy ridge was added to the Ramsar List of Wetlands of International Importance in 1981.This was because the lagoon was facing serious degradation due to siltation and choking of the seawater inlet channel, resulting in the proliferation of invasive freshwater species, the decrease in fish productivity, and an overall loss of biodiversity [1].
Fisheries and livelihoods in Tungabhadra basin: Current status and future possibilities – A working paper by Institute for Social and Economic Change
Posted on 30 Oct, 2011 01:02 PMThis study by Institute for Social and Economic Change (ISEC) aims at understanding the livelihood patterns of fishermen within the Tungabhadra sub basin, a tributary of river Krishna located in peninsular India. Lack of integrated approach in development initiatives and water management plans warrants the need for Integrated Water Resource Management to support livelihoods. The study focuses on fisheries as a source of livelihood, current status and institutional support available, people dependant on it, development initiatives and suggestions for improvements.
