This report attempts to introduce a prototype scoring system for the ecological status of rivers in India and illustrate it through the applications in several major river basins. This system forms part of the desktop environmental flow assessment and is based on a number of indicators reflecting ecological condition and sensitivity of a river. The unique aspect of this study is that it interprets, for the first time, the existing ecological information for Indian rivers in the context of environmental flow assessment. The report targets government departments, research institutions and NGOs which are engaged in environmental flow management and associated policy development, and suggests some subsequent steps in environmental flow work in India.

The book is written in the backdrop of the environmental impacts of and future requirements from the natural environment for rapid economic growth that has characterized recent economic history of China and India, especially over the past few decades. The environmental impacts of such rapid economic changes have been, more frequently than otherwise, degrading in character. Environmental impacts of economic activities create degraded natural ecosystems by over utilization of nature’s provisioning ecosystem services (from Himalaya to the Ocean), as well, by the use of the natural environment as sink for dumping of unmarketable products or unused inputs of economic activities. Such processes affect wide range of ecosystem processes on which the natural environment including human population depend on. Critical perspectives cast by various chapters in this book draw attention to the various ways in which space and power interact to produce diverse geographies of sustainability in a globalizing world. They also address the questions such as who decides what kind of a spatial arrangement of political power is needed for sustaining the environment. Who stands to gain (or lose) what, when, where, and why from certain geographical areas being demarcated as ecologically unique, fragile and vulnerable environments? Whose needs and values are being catered to by a given ecosystem service? What is the scope for critical inquiry into the ways in which the environment is imagined, represented and resisted in both geopolitical struggles and everyday life? The book provides insights to both academics from diverse disciplines and policy makers, civil society actors interested in mutual exchange of knowledge between China and India.

"CGIAR Challenge Program on Water & Food; Future Harvest"--Cover.

Basin water development and rural dynamics in the Krishna Basin have led to a degradation of downstream ecosystems manifesting itself by salinizing soil and groundwater, increasing pollution, disappearing mangroves and desiccating wetlands. Reversing this evolution requires the formal recognition of the environment as a water user in its own right and the implementation of an environmental water provision. This provision should be based on a two-tier allocation system with assured discharges in the irrigation canals of the delta and to the ocean. This will lead to further commitment of water resources but this is needed to reconcile the social, economic and environmental objectives of a sustainable development. Other measures facilitating integrated natural resources management from the local to the basin level are needed too.

This book presents results of scientific studies ranging from hydrological modelling to water management and policy issues in the Nile River basin. It examines the physical, hydrometeorological and hydrogeological description of the basin along with analysis in understanding the hydrological processes of the basin under the changing land-use stemming from population pressure and increased natural resources tapping. The book discusses the increased impact of climate change on the river flows, and such issues as water availability and demand, management and policy to offset the imbalance between demand and available resources. This book will be of interest to researchers, practitioners, water resources mangers, policy makers as well as graduate and undergraduate students. It is a useful reference text for ecohydrology, arid zone hydrology, hydrology of transboundary rivers and similar courses.
