The book provides an analysis of impacts of climate change on water for agriculture, and the adaptation strategies in water management to deal with these impacts. Chapters include an assessment at global level, with details on impacts in various countries. Adaptation measures including groundwater management, water storage, small and large scale irrigation to support agriculture and aquaculture are presented. Agricultural implications of sea level rise, as a subsequent impact of climate change, are also examined.
Agricultural water management is a vital practice in ensuring reduction, and environmental protection. After decades of successfully expanding irrigation and improving productivity, farmers and managers face an emerging crisis in the form of poorly performing irrigation schemes, slow modernization, declining investment, constrained water availability, and environmental degradation.More and better investments in agricultural water are needed. In response, the World Bank, in conjunction with many partner agencies, has compiled a selection of good experiences that can guide practitioners in the design of quality investments in agricultural water.The messages of 'Shaping the Future of Water for Agriculture: A Sourcebook for Investment in Agricultural Water Management' center around the key challenges to agricultural water management, specifically: • Building policies and incentives • Designing institutional reforms • Investing in irrigation systems improvement and modernization • Investing in groundwater irrigation • Investing in drainage and water quality management • Investing in water management in rainfed agriculture • Investing in agricultural water management in multipurpose operations • Coping with extreme climatic conditions • Assessing the social, economic, and environmental impacts of agricultural water investments 'Shaping the Future of Water for Agriculture' is an important resource for those interested and engaged in development with a focus on agricultural water.
"In order to face the challenge of disappointing returns on public investment in irrigation and drainage new solutions have emerged. These solutions are based on widely available technology and new management and governance options. The main message of Re-engaging in Agricultural Water Management is that the irrigation and drainage sector should not continue to be dealt with as a standalone sector, but should be integrated into a broader perspective, one that embraces the objectives of productivity growth, poverty reduction, natural resources management and environmental protection."

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.
There is increasing competition for water resources in the face of declining aquifer reserves and increasing risk in many areas of drought related to climate change. At the same time poor water management is damaging agriculture with problems such as salinization, waterlogging, erosion and run-off. This volume summarises the wealth of research on understanding and better management of water resources for agriculture. Part 1 reviews fundamental issues such as plant water use and soil water retention. Part 2 discusses ways of mapping and monitoring groundwater and surface water resources whilst Part 3 covers other sources such as rain and floodwater, waste and brackish water. Part 4 surveys developments in irrigation techniques such as drip irrigation and fertigation. The final sections in the book discuss ways of using water resources more efficiently such as site-specific and deficit irrigation techniques. With its distinguished editor and international team of expert authors, this wlll be a standard reference for agronomists, scientists involved in water and irrigation science as well as government and non-governmental organisations responsible for agriculture and water resource management.
As the world population increases, there is increasing competition for waterquantity as well as quality. Provided here is an up-to-date perspective on Available Water Resources (Part I), Water Conservation and Technology inAgricultural Systems (Part II), Problem Water Uses and Treatment (Part III),and Management and Policy Evaluation (Part IV). The book is an invaluable source of information for water resource planners, managers and policy makers, researchers and students, and irrigationists.
Irrigation water management is the act of timing and regulating irrigation water applications in a way that will satisfy the water requirement of the crop without the waste of water, soil, plant nutrients, or energy. It means applying water according to crop needs in amounts that can be held in the soil available to crops and at rates consistent with the intake characteristics of the soil and the erosion hazard of the site. Proper water management planning in irrigation must consider all uses of water, from the source of irrigation water to plant water use. Therefore, it is very important to differentiate between crop water requirements and irrigation or production system water requirements.This book entitled 'Agricultural Water Management' covers different issues and problematics of irrigated agriculture from water use in different irrigated systems to pollution generated by irrigated agriculture. The purpose of this book is to bring together and integrate the subject matter that deals with the equity, profitability and irrigation water pricing; modelling, monitoring and assessment techniques; sustainable irrigation development and management, and strategies for irrigation water supply and conservation. Moreover, the book also includes chapters that deal with new possibilities of improving irrigation techniques through the reuse of drainage water and wastewater, helping to reduce freshwater extractions. The worldwide contributions from outstanding scientists and experts provide detailed information about different topics and give overview of the current issues in water management. The book covers a wide range of current issues, reflecting on current problems and demonstrating the complexity of water management.
Agricultural water management includes many topics: farm-level and regional water management, irrigation, drainage, and salinity management of cultivated areas, collection and storage of rainfall in relation to soil properties and vegetation; the role of groundwater and surface water in nutrient cycling, exploitation and protection of water resources, control of flooding, erosion, and desertification. This book presents leading-edge research from around the world.

Water is critical to all human activities, but access to this crucial resource is increasingly limited by competition and the effects of climate change. In agriculture, water management is key to ensuring good and sustained crop yields, maintaining soil health, and safeguarding the long-term viability of the land. Water management is especially challenging on smallholder farms in resource-poor areas, which tend to be primarily rainfed and thus highly dependent on unreliable rainfall patterns. Sustainable practices can help farmers promote the development of soils, plants and field surfaces to allow maximum retention of water between rains, and encourage the efficient use of each drop of water applied as irrigation. Especially useful for farmers' groups, agricultural extension workers, NGOs, students and researchers working with farmers in dryland areas, this comprehensive yet concise book is a practical and accessible resource for anyone interested in sustainable water management.
