The Brahmaputra River basin is considered the lifeline of India. Lying in the northeast region of India, it represents nearly 30% of India's water resources potential and 41% of its total hydropower. In terms of the average discharge, it is the fifth largest river in the world. These resources notwithstanding, the northeast region remains woefully underdeveloped. A sustainable development of this region cannot be achieved without water resources development of the Brahmaputra River basin. To that end, an integrated basin-wide approach is needed, combining social, political, economic, administrative, cultural, and legal considerations with scientific and technological paradigms. It must involve people's participation. This book pools together the expertise, the in-depth knowledge and the experience of the people representing different disciplines bearing on the development of water resources. All the contributors have been connected closely with the Brahmaputra basin for many years.
