Book Description
This study assesses the short-term effects of large irrigation dams on household consumption in the northern part of Nigeria. Using two rounds of the Nigeria LSMS survey, we apply multinomial logit inverse probability weighting (MIPW) methods to construct matching samples across three different types of hydrological basins – dam basins, which are basins that contain large irrigation dams and the area upstream of such dams; downstream basins, which are located downstream of large irrigation dams; and non-dam basins, which are not associated with large irrigation dams. Our analyses particularly focus on the benefits provided by such dams for mitigating the drought risks faced by farm households. Drought is an important factor that affects adversely the welfare of farm household in Nigeria. Supplemental irrigation is often used during drought to provide water to crops.

Book Description
This Handbook offers an up-to-date collection of research on agricultural economics. Drawing together scholarship from experts at the top of their profession and from around the world, this collection provides new insights into the area of agricultural economics. The Routledge Handbook of Agricultural Economics explores a broad variety of topics including welfare economics, econometrics, agribusiness, and consumer economics. This wide range reflects the way in which agricultural economics encompasses a large sector of any economy, and the chapters present both an introduction to the subjects as well as the methodology, statistical background, and operations research techniques needed to solve practical economic problems. In addition, food economics is given a special focus in the Handbook due to the recent emphasis on health and feeding the world population a quality diet. Furthermore, through examining these diverse topics, the authors seek to provide some indication of the direction of research in these areas and where future research endeavors may be productive. Acting as a comprehensive, up-to-date, and definitive work of reference, this Handbook will be of use to researchers, faculty, and graduate students looking to deepen their understanding of agricultural economics, agribusiness, and applied economics, and the interrelationship of those areas.

Book Description
This book highlights the first comparative long-term analysis of the negative impacts of large dams on riverine communities and on free-flowing rivers in Africa, the Middle East and Asia. Following the Foreword by Professor Asit K. Biswas, the first section covers the 1956–1973 period, when the author believed that large dams provided an exceptional opportunity for integrated river basin development. In turn, the second section (1976–1997) reflects the author’s increasing concerns about the magnitude of the socio-economic and environmental costs of large dams, while the third (1998–2018) discusses why large dams are in fact not cost-effective in the long term.

Book Description
This study explores the conceptual and policy issues relating to the impact that irrigation has on crop production, farm income, inequities in income distribution and poverty alleviation. It also focuses, specifically, on poverty issues associated with head-tail water distribution inequity in an irrigation system.

Book Description
There are few issues that have greater impact on the life of mankind and the planet as a whole than the management of our most important natural resources water. This has only been realised in detail more recently by the general public as well as by many planners and decision-makers. Around the world they have begun to appropriate the critical importance of a reliable water supply for their future survival and sustainable development. Rivers are lifelines in countries like India serving different uses such as transport, agriculture, fisheries, personal hygiene and others. Conflicts over use of water resources must be settled through better water management policies. In many localities of the Earth water-related problems have become have become extremely acute, even critical. In some places they are the source of social instability and are a threat to international security. There is not the slightest doubt that, with further population increase and under the water business-as-usual scenario, these problems will become ever major acute, thus creating ever more instability. After decades of water waste, water pollution, and inability to provide basic water services to the poor we must fundamentally change the way we think about and manage water. We have to realise that water can no longer be considered to be a cheap and plentiful resource, which can be used abused or squandered without much concern for further human welfare.

Book Description
A guide to help planners and engineers to the improvment of future water projects. The past century of global experience on water projects is presented as the basis for creating new approaches. First-hand analyses, including 35 case studies from 25 countries, portray the influence of politicians, biologists, engineers, computer models and physicians on the spectacular successes and failures of the builders of canals and dams. By drawing on this experience, the author outlines methods for assessing, predicting and preventing major water-associated diseases around large dams, canals and irrigation systems.

Book Description
Viewed by some as symbols of progress and by others as inherently flawed, large dams remain one of the most contentious development issues on Earth. Building on the work of the now defunct World Commission on Dams, Thayer Scudder wades into the debate with unprecedented authority. Employing the Commission's Seven Strategic priorities, Scudder charts the 'middle way' forward by examining the impacts of large dams on ecosystems, societies and political economies. He also analyses the structure of the decision-making process for water resource development and tackles the highly contentious issue of dam-induced resettlement, illuminated by a statistical analysis of 50 cases.

Book Description
One of the most controversial issues of the water sector in recent years has been the impacts of large dams. Proponents have claimed that such structures are essential to meet the increasing water demands of the world and that their overall societal benefits far outweight the costs. In contrast, the opponents claim that social and environmental costs of large dams far exceed their benefits, and that the era of construction of large dams is over. A major reason as to why there is no consensus on the overall benefits of large dams is because objective, authoritative and comprehensive evaluations of their impacts, especially ten or more years after their construction, are conspicuous by their absence. This book debates impartially, comprehensively and objectively, the positive and negative impacts of large dams based on facts, figures and authoritative analyses. These in-depth case studies are expected to promote a healthy and balanced debate on the needs, impacts and relevance of large dams, with case studies from Africa, Asia, Australia, Europe and Latin America.

Book Description
By the year 2000, the world had built more than 45,000 large dams to irrigate crops, generate power, control floods in wet times and store water in dry times. Yet, in the last century, large dams also disrupted the ecology of half the world's rivers, displaced tens of millions of people from their homes and left nations burdened with debt. Their impacts have inevitably generated growing controversy and conflicts. Resolving their role in meeting water and energy needs is vital for the future and illustrates the complex development challenges that face our societies. The Report of the World Commission on Dams: - is the product of an unprecedented global public policy effort to bring governments, the private sector and civil society together in one process - provides the first comprehensive global and independent review of the performance and impacts of dams - presents a new framework for water and energy resources development - develops an agenda of seven strategic priorities with corresponding criteria and guidelines for future decision-making. Challenging our assumptions, the Commission sets before us the hard, rigorous and clear-eyed evidence of exactly why nations decide to build dams and how dams can affect human, plant and animal life, for better or for worse. Dams and Development: A New Framework for Decision-Making is vital reading on the future of dams as well as the changing development context where new voices, choices and options leave little room for a business-as-usual scenario.
