Book Description
Efficient and effective irrigation of the land can have a dramatic effect on the agricultural output and the economic well-being of a community. At the heart of effective irrigation lies the problem of lifting or pumping water, and this handbook surveys the water-lifting technologies that are available and appropriate for smallholdings. It is a detailed and practical review of the options, especially for irrigation but also for other purposes, and the costs and general suitability of the different technologies are examined with the aim of enabling farmers and policymakers to make informed choices. This is an updated and expanded new edition of a book formerly called 'Water Pumping Devices'.

Book Description
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.

Book Description
This last volume of the Energy in World Agriculture series is in many ways the series' Alpha and its Omega. It addresses the broad issues related to the use of energy in agricultural production, and also characterizes and quantifies the energy involvements of many agricultural production technologies. It is a compilation of descriptive and analytical information and design principles and data of energy use in this field. A significant aspect is the relationship between energy and agricultural productivity, increased knowledge and resulting improved management of energy-consuming operations on the farm. Information provided here has not been published elsewhere before. Throughout the book are examples of the important role that energy inputs have played in increasing productivity of the world's agricultural systems. Together with a revived interest in energy for agricultural production due to increases in energy costs, this volume meets that interest with valuable information and insights.

Book Description
Were water considered an industry, it would be one of the largest in the United States, surely the most capital-intensive, and the most closely regulated by Congress. Yet as Peter Rogers argues in this readable, pragmatic, and scientifically grounded assessment of national water issues, it would also be one of the most fragmented and least coherent areas of public policy. Rogers brings together all aspects of water (and water use) to look at policy formation from technical, economic, and political points of view. He shows why these separate perspectives must be considered simultaneously if intelligent policies are to be developed to protect this indispensable resource for present and future generations.Although water use has declined since 1980, the U.S. still consumes more than twice as much water per capita as any other country in the world. Weighing current resources against future demand, Rogers covers a host of complex water issues facing a thirsty, affluent nation. He explains why the federal role needs to be developed and clarified in a number of areas - from changing the unrealistic expectations of the American public for clean water at any cost to financing the rebuilding of infrastructure that is nearly a century old, from reforming intergovernmental relations and the committee structure in Congress to preserving and restoring wetlands and developing a national drought management policy.Of the two basic approaches to policy formation - spelling out desirable norms and attempting to achieve them, or building pragmatically on what has been feasible in the past - Rogers advocates the feasibility approach. The challenge, he asserts, is to develop a federal policy that will reform the historical patchwork of state-state and state-federal agreements and allow them to work together without abrupt dislocations.Peter Rogers is Gordon McKay Professor of Environmental Engineering and Professor of City Planning at Harvard University.
