The Irrigation Sector

India's irrigated agriculture sector has been basic to India's economic development and poverty alleviation. One of India's major achievements is its rapid expansion of irrigation and drainage infrastructure. However, the major emphasis on development has been achieved at a cost. The importance put on new construction has diverted attention away from the need to ensure the quality, productivity, and sustainability of the services. Further, a governmental subsidy based approach has been used and this has resulted in irrigation and drainage services which, while enabling significantly higher productivity than from non-irrigated lands, are well below their potential. 'The Irrigation Sector' discusses directions for future growth, the framework for reform, and the reform agenda.

One irrigation subsector goal of the Asian Development Bank is to produce more food with less water. Estimates suggest that food production in the developing world must double by. By that year, urban and industrial water demand will have increased from 20% of total regional demand to 40% (about 80% of that water demand is for irrigation). This publication helps define core support areas in the irrigation subsector and set the course for country partnership strategy investments in irrigation for lending and nonlending assistance. See how this guidance note can assist and strengthen the preparation of projects that increase food productivity and security, use water within the resource availability limits, and produce long-term benefits.

Increasing the area under irrigation and the widespread adoption of seed-fertilizer technology were the major factors that contributed to enhanced rice production in Sri Lanka, enabling the country to achieve self-sufficiency in rice. In recent years, there has been a shift in emphasis from expanding the irrigated land base to enhancing the productivity of irrigated land through diversification of agriculture and improvement of rice production, with better water management in irrigation schemes. This report attempts to assess how the irrigation sector in Sri Lanka is adapting itself to these new challenges. It analyzes the future direction of irrigation in Sri Lanka in light of recent trends in public and private investment in this sphere, and the revolution in groundwater development brought about by the poor performance and gradual deterioration of existing irrigation schemes.

Mediterranean irrigation is diverse due to, among other factors, the relative importance of water in the economy of each country, varied levels of aridity, heterogeneous levels economic, social and technological levels of development, and differences in political and social organization. However, most of the Mediterranean countries face similar problems to meet their water demands because of the scarcity and variability of renewable resources, growing water requirements from non-agricultural sectors, increasing environmental concerns related to water quality and environmental degradation, a social demand for larger public participation, and important technological changes. The time has come to reconsider the “not one drop lost to the sea” philosophy of yesteryears largely and to 'live within limits'. This book focuses on eight selected countries (Tunisia, Morocco, Spain, France, Italy, Turkey, Israel and Egypt) and provides a comparative perspective that both thoroughly explores their specificities and identifies the common challenges faced by the irrigation sector in these countries. The book has been written at a critical moment, when the continued application of a supply-side water management model is revealing its unsustainable nature in numerous places; when significant technological changes are taking place in the irrigation sector; when new forms of management and governance are widely held as badly needed; and finally, when climate change is compounding many of the difficulties that have characterized irrigation policies and practices in the past decades. This complicated future context makes Mediterranean irrigation face various political dilemmas on water management, raising social tensions, triggering territorial and land conflicts, and stimulating new technological developments. This book provides a timely analysis of the particular trajectory of eight Mediterranean countries in these uncertain transformations, and attempts to identify the best strategies to avert or overcome future risks.

Only 4 percent of arable land in sub-Saharan Africa is irrigated, using just 2 percent of the available water resources. Furthermore, 18 percent of the area equipped for irrigation is not utilized at all and the intensity of use varies between 50 percent and 80 percent. This highlights the huge potential available for intensifying and expanding irrigated area, provided that the investments required can be successfully mobilized. However, it must be noted that if investments in irrigation are to yield satisfactory returns, investments must also be made in a series of related activities. Current global figures for the amount of private investment in irrigation confirm that good returns can indeed be achieved. Prospects for sub-Saharan Africa would be far more favorable if public development assistance, particularly foreign direct investments, did not show declining trends.

Between the years 2000 and 2025 the world?s population is expected to rise from six billion to about 8 billion. At the present time, irrigated agriculture provides one third of world food output. So the advance of the irrigated sector on a global scale is a vital part of the development of the human race's capacity to feed itself. This requires many skills, including an economic understanding of the role of water in the irrigation and drainage of farmland. The purpose of this book is to provide a text in securing such an understanding that will assist both students and professionals in the fields of agriculture, development studies, geography, hydrology and planning. As an introduction to the subject, no prior knowledge of economic theory is assumed. The scope of the book is wide both in its analysis and its geographical coverage. A general introduction to irrigation and to economics is followed by a treatment of farmer’s need for irrigation water and the costs they face in accessing it. Three chapters cover the supply-side: infrastructure, operation and maintenance. An introduction is next given to the economic evaluation of irrigation and drainage projects continuing with a consideration of water allocation between sectors at the regional level. The book ends with a summary of the analysis as well as sixteen proposals for policy development. The approach is to make it possible for readers from a variety of backgrounds to readily access the subject matter. Each chapter begins with general, analytic themes and is followed by one or two detailed case studies drawn from Australia, Brazil, England, India, the Mediterranean, Mexico, Pakistan, Palestine, the Philippines and the USA. The desire is to continually interrelate theory and fieldwork in an argument that is clearly expressed, well-structured and as easy to read as the subject permits. The book is the first of its kind published since 1981.

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
