A perusal of environment impact assessments for hydel projects in Uttarakhand brings out various deficiencies in the reports, and the unstudied manner in which such projects have been embarked upon. That many more of such projects have been proposed points to the muddled direction adopted for energy supply, reminding us of the hydropower story in the United States.

The processes that control climate in the tropics are poorly understood. We applied compound-specific hydrogen isotopes (D) and the TEX86 (tetraether index of 86 carbon atoms) temperature proxy to sediment cores from Lake Tanganyika to independently reconstruct precipitation and temperature variations during the past 60,000 years.

A considerable amount of research has focused on how and when the Tibetan plateau formed in the wake of tectonic convergence between India and Asia1.

The stability of the margins of the Himalayan

Stream flow samples were collected with distances downstream over a river stretch of 6.5km. The rivers transcend different land use pattern and took it source from a large refuse dump in the central market (Ogbe market) Ile-Ife before flowing into a dam. Seven sampling points were carefully selected downstream the channel.

Power-generating companies can get a minimum fixed sum irrespective of how much electricity they produce Capacity Index (CI) = declared capacity

A series of hydropower projects on the Bhagirathi and the Alaknanda may reduce the Ganga to a trickle. But project proponents will still be making money.

Nourisher of an ancient civilization, the Ganga could be gasping for its survival. Every few kilometres the water of its tributaries will be diverted to produce power. While there may not be enough flow to run the turbines, there

The breaching of embankments in the upstream areas of the Kosi river, in Kusaha village in Nepal, has resulted in yet another round of floods in north Bihar, in the districts of Supaul, Saharsa, Araria, Madhepura, Katihar and Purnia. The disaster this time is much larger than usual. More than three million people have been affected and a million have been forced to seek higher ground. (Editorial)
