Ignoring precaution, MoEF clears a project which has been categorically rejected by majority Standing Committee of the NBWL
MoEF, which holds the mandate of safeguarding country's environment, has given a completely unjustifiable wildlife clearance to the 1750 MW Demwe Lower Hydroelectric dam on the Lohit river in Arunachal Pradesh (http://www.moef.nic.in/downloads/public-information/Demwe_Lower_Hydroelectric_project.pdf), in face of severe opposition from civil society, experts across country and all the independent members of National Board for Wildlife. This shocking decision has come at the heels of one more such clearance given by MoEF to 300 MW Alkananda project in Uttarakhand, which has been rejected twice by FAC and given a negative recommendation by WII.

Inducing vulnerabilities in a fragile landscape: The implications of hydropower development in a seismically active zone - An article in EPW
After the earthquake that shook Sikkim in November 2011, the safety of the dams being constructed on the Teesta is being questioned by the communities that live along it

Close to 30 hydroelectric projects are being planned on the Teesta and its tributaries. Not only is this river an essential part of Lepcha identity and life, but it also flows through a fragile zone. In this article first published in the Economic and Political Weekly (EPW), Kanchi Kohli examines the ramifications of this policy.
Diverting rivers for linking, a catastrophic idea: Questioning the state impetus to river inter-linking despite uncertain economic, social and ecological benefits
The economic feasibility of river interlinking is still debatable, while studies show that it will cause social and ecological harm. Despite this, states are still taking this program forward. Gopal Krishna examines this phenomenon.

Small hydro: Too small for a national mission - The need for an assimilated national mission for renewable energy in India
India has set high targets for solar energy through its Jawaharlal Nehru National Solar Mission. However, this may take focus away from other renewable energy sources, especially small hydro which is a high density resource. This brief by the Observer Research Foundation examines whether small hydro qualifies for a national mission.

Rural water access: Governance and contestation in a semi-arid watershed in Udaipur, Rajasthan: A paper in EPW
Recent policy has encouraged a shift towards community management of water infrastructure through the creation of decentralised institutions.This also implies a shift from large to small structures and institutions. This however presumes the existence of a homogeneous 'community', and does not necessarily acknowledge the effect of various separate groups within such a community on these institutions. This paper published in Economic and Political Weekly (EPW) examines the impacts of this shift towards decentralised irrigation management on different groups residing in six villages in Rajasthan.

These manuals are aimed at expert appraisal committees, and hope to improve the quality of appraisal of projects. These will also provide a template for use by organisations and consultants developing the EIA reports.cover page of the EIA guidance manual-ship breaking yards

Climate change risk - An adaptation and mitigation agenda for Indian cities - A paper published in the journal Environment and Urbanisation
This paper outlines the much needed adaptation and mitigation agenda for cities in India where the urban population is likely to grow by around 500 million over the next 50 years.

The paper dwells on the likely changes that climate change is expected to bring in temperature, precipitation and extreme rainfall, drought, river and inland flooding, storms/storm surges/coastal flooding, sea-level rise and environmental health risks, and who within urban populations will be at risk.

The HKH region is one of the most dynamic, fragile, and complex mountain systems in the world as a result of tectonic activity and the rich diversity of climates, hydrology, and ecology. The high Himalayan region is the freshwater tower of South Asia and has the highest concentration of snow and glaciers outside the polar regions giving it the name Third Pole.

Framework for valuing ecosystem services in the Himalayas - An ICIMOD technical report

This has been a generic first attempt that can be fine-tuned and customised for each type of ecosystem and each kind of service value. Ecosystem services are defined by the Millennium Ecosystem Assessment as ‘the benefits people obtain from ecosystems'.

Mountains occupy 24% of the global land surface area and are home to 12% of the world’s population. Mountains have an ecological, aesthetic, and socioeconomic significance, not only for those living in the mountain areas, but also for people living beyond them. However, the importance of ecosystem services arising from mountains is not properly recognised. The HKH region is endowed with a rich variety of gene pools and species, and ecosystems of global importance. It is a storehouse of biological diversity and a priority region in many global conservation agendas. The region has many unique ecosystems that play a critical role in protecting the environment and in providing livelihoods for much of Asia and beyond.
