This book aims to bring forth and address the major issues confronting the irrigation sector of India and also to suggest policy pointers to sustain it. As the policy and reform canvas is large for a huge and diverse country, this book has particular focus on the most important and immediate issues and future options. The chapters not only focus on new research, in-depth analysis and technical details, but also provide a balanced review of the state of irrigation sector and comprehensive presentation of major issues, challenges and future options. With the presentation of in-depth analysis and synthesis of available knowledge, the work can act as a handbook for major irrigation water issues, actual policy changes, and potential reform that could turnaround the sector. Given the temporal and spatial data analysis of the irrigation sector, this book will be effective and useful as a research and teaching tool to students and researchers both in India and globally. Besides its professional audience within the academic, research and policy community, the non-technical format of the book will appeal to a general audience in the media, policy, and donor circles.

Desenvolvimento sustentado da irrigacao na India. Pesquisa, manejo, sistemas e experiencias praticas.

Irrigated agriculture has played a critical role in the economic and social development of the United States--but it is also at the root of increasing controversy. How can irrigation best make the transition into an era of increasing water scarcity? In A New Era for Irrigation, experts draw important conclusions about whether irrigation can continue to be the nation's most significant water user, what role the federal government should play, and what the irrigation industry must do to adapt to the conditions of the future. A New Era for Irrigation provides data, examples, and insightful commentary on issues such as Growing competition for water resources. Developments in technology and science. The role of federal subsidies for crops and water. Uncertainties related to American Indian water rights issues. Concern about environmental problems. And more. The committee identifies broad forces of change and reports on how public and private institutions, scientists and technology experts, and individual irrigators have responded. The report includes detailed case studies from the Great Plains, the Pacific Northwest, California, and Florida, in both the agricultural and turfgrass sectors. The cultural transformation brought about by irrigation may be as profound as the transformation of the landscape. The committee examines major facets of this cultural perspective and explores its place in the future. A New Era for Irrigation explains how irrigation emerged in the nineteenth century, how it met the nation's goals in the twentieth century, and what role it might play in the twenty-first century. It will be important to growers, policymakers, regulators, environmentalists, water and soil scientists, water rights claimants, and interested individuals.

With a rapidly expanding economy many changes are taking place in India today. The business-as-usual (BAU) scenario, which assumes the continuation of current trends of key water demand drivers, will meet the future food demand. However, it leads to a severe regional water crisis by 2050, where many river basins will reach closure, will be physically water-scarce and will have regions with severely overexploited groundwater resources. While the alternative scenarios of water demand show both optimistic and pessimistic water futures, the scenario with additional productivity growth is the most optimistic, with significant scope for reducing future water demand.
