India is endowed with varied topographical features, such as high mountains, extensive plateaus, and wide plains traversed by mighty rivers. Divided into four sections this book provides a comprehensive overview of water resources of India. A detailed treatment of all major river basins is provided. This is followed by a discussion on major uses of water in India. Finally, the closing chapters discuss views on water management policy for India.
Few people actively engaged in India's water sector would deny that the Indian subcontinent faces serious problems in the sustainable use and management of water resources. Water resources in India have been subjected to tremendous pressures from increasing population, urbanization, industrialization, and modern agricultural methods. The inadequate access to clean drinking water, increase in water related disasters such as floods and droughts, vulnerability to climate change and competition for the resource amongst different sectors and the region poses immense pressures for sustainability of water systems and humanity. Water Security in India addresses these issues head on, analyzing the challenges that contemporary India faces if it is to create a water-secure world, and providing a hopeful, though guarded, road-map to a future in which India's life-giving and life-sustaining fresh water resources are safe, clean, plentiful, and available to all, secured for the people in a peaceful and ecologically sustainable manner.
This comprehensive volume explores the interface between politics and policy making in the water management sector of India. The authors discuss the nature of the political discourse on water management in India, and what characterizes this discourse. They also explore how this discourse has influenced the process of framing water related policies in India, particularly through the ‘academics-bureaucrat-politician’ nexus and the growing influence of the civil society groups on policy makers, which are the defining feature of this process, and which have produced certain policy outcomes that are not supported by sufficient scientific evidence. The book reveals that the social and management sciences, despite being increasingly relevant in contemporary water management, are unable to impress upon traditional, engineer-dominated water administration to seek solutions to complex water problems owing to a lack of interdisciplinary perspective in their research. The authors also examine the current deadlock in undertaking sectoral reforms due to existing water policies not being honoured. This collection includes several research studies which suggest legal, institutional policy alternatives for addressing the problems in areas such as irrigation, rural and urban water supply, flood control and adaptation to climate variability and change. It was originally published as a special issue of the International Journal of Water Resources Development.

The WRHP-2016 was organised in association with the Indian Institute of Technology, Roorkee, Uttrakhand Jal Vidyut Nigam Limited and the Indian Society for Hydraulics, Pune and was held in University of Petroleum and Energy Studies, Dehradun, India from June 17-18, 2016.
Scientific evidence shows that most glaciers in South Asia's Hindu Kush Himalayan region are retreating, but the consequences for the region's water supply are unclear, this report finds. The Hindu Kush Himalayan region is the location of several of Asia's great river systems, which provide water for drinking, irrigation, and other uses for about 1.5 billion people. Recent studies show that at lower elevations, glacial retreat is unlikely to cause significant changes in water availability over the next several decades, but other factors, including groundwater depletion and increasing human water use, could have a greater impact. Higher elevation areas could experience altered water flow in some river basins if current rates of glacial retreat continue, but shifts in the location, intensity, and variability of rain and snow due to climate change will likely have a greater impact on regional water supplies. Himalayan Glaciers: Climate Change, Water Resources, and Water Security makes recommendations and sets guidelines for the future of climate change and water security in the Himalayan Region. This report emphasizes that social changes, such as changing patterns of water use and water management decisions, are likely to have at least as much of an impact on water demand as environmental factors do on water supply. Water scarcity will likely affect the rural and urban poor most severely, as these groups have the least capacity to move to new locations as needed. It is predicted that the region will become increasingly urbanized as cities expand to absorb migrants in search of economic opportunities. As living standards and populations rise, water use will likely increase-for example, as more people have diets rich in meat, more water will be needed for agricultural use. The effects of future climate change could further exacerbate water stress. Himalayan Glaciers: Climate Change, Water Resources, and Water Security explains that changes in the availability of water resources could play an increasing role in political tensions, especially if existing water management institutions do not better account for the social, economic, and ecological complexities of the region. To effectively respond to the effects of climate change, water management systems will need to take into account the social, economic, and ecological complexities of the region. This means it will be important to expand research and monitoring programs to gather more detailed, consistent, and accurate data on demographics, water supply, demand, and scarcity.
When it comes to water, we flush and forget. We use, abuse and almost never recycle. Water sector in India, since the 1990s, has seen some new ideas formalised legally and institutionally, while others are still emerging and evolving. Confronting the reality of current water management strategies, this volume discusses the state of the Indian water sector to uncover solutions that can address the imminent water crises. This book: Analyses the growing water insecurity, increase in demand, inefficiency in water use, and growing inequalities in accessing clean water; Sheds light on water footprint in agricultural, industrial and urban use, pressures on river basin management, depleting groundwater resources, patterns of droughts and floods, watershed based development and waste water and sanitation management; Examines water conflicts, lack of participatory governance mechanisms, and suggests an alternative framework for water regulation and conflict transformation; Highlights the relationship between gender discourse and water governance; Presents an alternative agenda for water sector reforms. This volume, with hopes for a more water secure future, will interest scholars and researchers of development studies, environment studies, public policy, political studies, political sociology, and, NGOs, media and think tanks working in this area.
This book is about the politics of water resource development and management in India, with special reference to the Narmada river waters dispute. The author draws on a wealth of studies on Narmada as also his own research to analyse the controversy from the perspective of a political scientist. The author analyses three aspects of the conflict over developing the waters of the Narmada: - The politics of the inter-state river water dispute over Narmada waters in the context of Indian centre-state and inter-state relationships and the constitutional and legal mechanisms for resolving disputes among riparian states. - The Narmada upstream-downstream politics implicit in the battle between downstream Gujarat and Rajasthan versus upstream Madhya Pradesh and Maharashtra. - The much-publicized struggle between those for and others against the construction of the gigantic Sardar Sarovar dam. Given the highly contentious nature of these struggles, the author objectively highlights how and why the outcomes of such struggles have largely depended on the realities of power.
This book contains both practical and theoretical aspects of groundwater resources relating to geochemistry. Focusing on recent research in groundwater resources, this book helps readers to understand the hydrogeochemistry of groundwater resources. Dealing primarily with the sources of ions in groundwater, the book describes geogenic and anthropogenic input of ions into water. Different organic, inorganic and emerging contamination and salinity problems are described, along with pollution-related issues affecting groundwater. New trends in groundwater contamination remediation measures are included, which will be particularly useful to researchers working in the field of water conservation. The book also contains diverse groundwater modelling examples, enabling a better understanding of water-related issues and their management. Groundwater Geochemistry: Pollution and Remediation offers the reader: An understanding of the quantitative and qualitative challenges of groundwater resources An introduction to the environmental geochemistry of groundwater resources A survey of groundwater pollution-related issues Recent trends in groundwater conservation and remediation Mathematical and statistical modeling related to groundwater resources Students, lecturers and researchers working in the fields of hydrogeochemistry, water pollution and groundwater will find Groundwater Geochemistry an essential companion.
This book is divided into four parts. The first part, Preliminaries, begins by introducing the basic theme of the book. It provides an overview of the current status of water resources utilization, the likely scenario of future demands, and advantages and disadvantages of systems techniques. An understanding of how the hydrological data are measured and processed is important before undertaking any analysis. The discussion is extended to emerging techniques, such as Remote Sensing, GIS, Artificial Neural Networks, and Expert Systems. The statistical tools for data analysis including commonly used probability distributions, parameter estimation, regression and correlation, frequency analysis, and time-series analysis are discussed in a separate chapter. Part 2 Decision Making, is a bouquet of techniques organized in 4 chapters. After discussing optimization and simulation, the techniques of economic analysis are covered. Recently, environmental and social aspects, and rehabilitation and resettlement of project-affected people have come to occupy a central stage in water resources management and any good book is incomplete unless these topics are adequately covered. The concept of rational decision making along with risk, reliability, and uncertainty aspects form subject matter of a chapter. With these analytical tools, the practitioner is well equipped to take a rational decision for water resources utilization. Part 3 deals with Water Resources Planning and Development. This part discusses the concepts of planning, the planning process, integrated planning, public involvement, and reservoir sizing.The last part focuses on Systems Operation and Management. After a resource is developed, it is essential to manage it in the best possible way. Many dams around the world are losing some storage capacity every year due to sedimentation and therefore, the assessment and management of reservoir sedimentation is described in details. No analysis of water resources systems is complete without consideration of water quality. A river basin is the natural unit in which water occurs. The final chapter discusses various issues related to holistic management of a river basin.
