This book takes stock of micro irrigation systems (MIS), the technological intervention in India's agricultural and water management sectors, over the past couple of decades. Based on empirical research from the major agriculturally dynamic states, viz., Gujarat, Rajasthan, Maharashtra, Tamil Nadu, Andhra Pradesh and Karnataka, the book provides a nuanced understanding and objective assessment of the implementation and adoption of MIS across these states. It addresses several of the questions related to adoption and impacts of MIS in India. On the adoption side, the key question that the book addresses is which segment of the farming community adopts MIS across states? The impacts analysed include those on physical, agronomic and economic aspects. At the macro level, the question being asked is about the future potential of MIS in terms of saving water from agriculture and making more water available for environment. The book also addresses the question of the positive/negative externalities and real social benefits and costs from the use of MIS, a major justification for heavy capital subsidies for its purchase by farmers. It also brings out certain critical concerns pertaining to MIS adoption, which need to be addressed through more empirical research based on longitudinal panel/ cross sectional data. The book would be of great use to researchers (agricultural water management, irrigation economics), students of water resource engineering, irrigation engineering and water resources management, as well as to policy makers and agricultural water management experts - national and international.

This book highlights the multi-pronged strategy for achieving sustainable rural domestic water supply in India. It deepens the understanding of groundwater (predominant source of water supply) behaviour in response to natural processes in different geological settings, analyses the factors influencing the performance of water supply schemes; identifies the conditions under which groundwater-based drinking water sources become sustainable, suggests measures for improving the sustainability of drinking water wells in hard rock regions (covering 2/3rd of India's geographical area), presents a decision-making framework for planning rural water supply schemes in the country for ensuring long-term sustainability, and suggests physical strategies and policy measures for achieving them. The analyses for development and validation of various models that explain groundwater system behaviour and performance of rural water supply schemes are undertaken for different geological settings in Maharashtra, as the state represents a microcosm of the various hydrological, topographical, and geohydrological conditions encountered in the country. The final analysis for proposing nation-wide strategies considers the various hydrological, geological, geohydrological, and topographical and climatic settings and groundwater contamination and pollution in the country.

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.

This book addresses strategies for food security and sustainable agriculture in developing economies. The book focuses primarily on India, a fast developing economy, whose natural resource base comprising land and water supporting agricultural production is not only under enormous stress, but also complex and not amenable to a uniform strategy. It critically reviews issues which continue to dominate the debate on water management for agricultural and food production. The book examines the validity of the claim that large water resources projects cause serious social and environmental damages using global and national datasets. The authors examine claims that the future of Indian agriculture is in rain-fed farming supported by small water harvesting. They question whether water-abundant eastern India could become the granary of India, through a groundwater revolution with the right policy inputs. In the process, they look at the less researched aspect of the food security challenge, which is land scarcity in eastern India. The book analyzes the physical, economic and social impacts of large-scale adoption of micro irrigation systems, using a farming system approach for north Gujarat. Through an economic valuation of the multiple use benefits from tank systems in western Orissa, it shows how value of water from large public irrigation systems could be enhanced. The book also looks at the reasons for the limited success in bringing about the much needed institutional reforms in canal irrigation for securing higher productivity and equity using case studies of Gujarat, Madhya Pradesh and Maharashtra. Finally it addresses how other countries in the developing world, particularly Sub-Saharan Africa could learn from Indian experience.

It is becoming increasingly recognized that for the optimal sustainable development and use of natural resources, an integrated approach to water management, agriculture, food security and energy is required. This "nexus" is now the focus of major attention by researchers, policy-makers and practitioners. In this book, the authors show how these issues are being addressed in India as part of its economic development, and how these can provide lessons for other developing nations. They address the conflicting claims of water resources for irrigation and hydropower, where both are scarce at the national level for fostering water and energy security. They also consider the relationship between water for irrigated agriculture and household use and its impact on rural poverty. They identify weaknesses in the current hydropower development programme in India that are preventing it from being an ecologically sustainable, socially just and economically viable solution to meeting growing energy demand. The empirical analyses presented show the enormous scope for co-management of water, energy, agricultural growth and food security through appropriate technological interventions and market instruments.

Water Productivity and Food Security: Global Trends and Regional Patterns, Volume Three reviews the need for water productivity improvements in agriculture, addressing three distinct questions pertaining to agricultural water productivity improvement in developing countries, including what are the regions where water is a limiting factor for raising agricultural outputs and water productivity improvements, what are the technological measures in irrigation that can raise agricultural water productivity and result in water saving at various scales, and what opportunities exist in the developing economies of South Asia and Africa for raising water productivity and improving water economy at basin scale. This book provides a framework to characterize river basins based on water availability, water supplies, water uses and water demands to ascertain the need and measures available for improving crop water productivity that would be effective at various scales, i.e., plant-level, plot-level, irrigation system level and basin level. This is an essential reference for anyone interested in water management and agriculture.

From Catchment Management to Managing River Basins: Science, Technology Choices, Institutions and Policy synthesizes key scientific facts crucial for catchment assessment, planning and river basin water accounting. The book presents extensive reviews of international literature on catchment hydrology, forest hydrology and other hydrological processes, such as groundwater-surface water interactions. It discusses not only the science of catchment assessment and planning, but also the catchment planning process. It documents several of the positive international experiences with integrated catchment management and integrated basin management, distilling key learnings. Case studies from India and other parts of South Asia are also included, along with new pilot studies. Finally, the book discusses the theoretical and operational aspects of integrated catchment management and integrated water management in river basins using international best practices and case studies.

Water Policy Science and Politics: An Indian Perspective presents the importance of politics and science working together in policymaking in the water sector. Many countries around the developed and developing world, including India, are experiencing major water scarcity problems that will undoubtedly increase with the impacts of climate change. This book discusses specific topics in India's water, agriculture and energy sectors, focusing on scientific aspects, academic and political discourse, and policy issues. The author presents cases from the interrelated sectors of water resources, supplies, sanitation, and energy and climate, including controversial topics that illustrate how science and politics can work together.

This book highlights the institutional, legal, and policy measures to manage water pollution in India, and discusses how effective they have been in improving the overall quality of the country's surface and groundwater resources. It also reviews the status of wastewater generation, collection and treatment in urban areas to provide insights into the gaps in wastewater treatment. Further, it offers a detailed analysis of the wastewater treatment systems available and examines the human health impacts of water pollution in the country, as well as the future trajectory of investment in wastewater treatment systems and potential sectors for reuse and recycling of wastewater, briefly assessing the market demand for treated wastewater. Lastly, it investigates the factors influencing the environmental sustainability and economic viability of wastewater treatment as well as future areas of research in the field.

Rural Water Systems for Multiple Uses and Livelihood Security covers the technological, institutional, and policy choices for building rural water supply systems that are sustainable from physical, economic, and ecological points-of-view in developing countries. While there is abundant theoretical discourse on designing village water supply schemes as multiple use systems, there is too little understanding of the type of water needs in rural households, how they vary across socio-economic and climatic settings, the extent to which these needs are met by the existing single use water supply schemes, and what mechanisms exist to take care of unmet demands. The case studies presented in the book from different agro ecological regions quantify these benefits under different agro ecological settings, also examining the economic and environmental trade-offs in maximizing benefits. This book demonstrates how various physical and socio-economic processes alter the hydrology of tanks in rural settings, thereby affecting their performance, also including quantitative criteria that can be used to select tanks suitable for rehabilitation.

Groundwater Economics and Policy in South Asia is a reference guide focusing on groundwater management and groundwater economics in South Asia.
