Download or read book Water Lifting Devices written by Peter L. Fraenkel and published by Food and Agriculture Organization of the United Nations. This book was released on 2006 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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'.

Download or read book Small Wind Turbines for Electricity and Irrigation written by Mario Alejandro Rosato and published by CRC Press. This book was released on 2018-06-27 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: This practical book deals with the technology of small-power wind turbines as opposed to widely diffused industrial wind turbines and wind farms. It covers the most common wind turbine technologies in the small power segment: horizontal axis both for electrical generation and water pumping, vertical axis of the Darrieus type, and vertical axis of the Savonius type. With each chapter following the same didactic scheme—a theoretical explanation and practical examples showing calculation procedures—it allows anybody with basic technical knowledge to design and build a small wind turbine for any site. A set of simple spreadsheets is available for download, each providing further examples of how to solve specific design problems and allowing the reader to play with changing parameters and see what-if. This simple trial-and-error learning process allows beginners to develop the feeling of the orders of magnitude involved in the design of a small wind power system, its potential advantages on other alternative solutions, and its limitations under some special circumstances.

Available in PDF, EPUB and Kindle. Book excerpt: Increasing the efficiency of water use and enhancing agricultural water productivity at all levels of the production chains are becoming priorities in a growing number of countries. In particular, shifting to modern on-farm irrigation practices can contribute to a substantial increase in both water use efficiency and water productivity. The objective of this handbook is to provide a practical guide on the use of pressurized irrigation techniques to farmers, irrigation technicians, and extension workers in the field. In this second edition, the handbook has been considerably revised, including new chapters on low-cost drip irrigation and pipe distribution systems for smallholders.--Publisher's description.
Download or read book Why America Is Not a New Rome written by Vaclav Smil and published by MIT Press. This book was released on 2010-01-29 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation of the America-Rome analogy that goes deeper than the facile comparisons made on talk shows and in glossy magazine articles. America's post–Cold War strategic dominance and its pre-recession affluence inspired pundits to make celebratory comparisons to ancient Rome at its most powerful. Now, with America no longer perceived as invulnerable, engaged in protracted fighting in Iraq and Afghanistan, and suffering the worst economic downturn since the Great Depression, comparisons are to the bloated, decadent, ineffectual later Empire. In Why America Is Not a New Rome, Vaclav Smil looks at these comparisons in detail, going deeper than the facile analogy-making of talk shows and glossy magazine articles. He finds profound differences. Smil, a scientist and a lifelong student of Roman history, focuses on several fundamental concerns: the very meaning of empire; the actual extent and nature of Roman and American power; the role of knowledge and innovation; and demographic and economic basics—population dynamics, illness, death, wealth, and misery. America is not a latter-day Rome, Smil finds, and we need to understand this in order to look ahead without the burden of counterproductive analogies. Superficial similarities do not imply long-term political, demographic, or economic outcomes identical to Rome's.
Download or read book Walking the Nexus Talk written by Alessandro Flammini and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to global transformational trends, such as population growth, economic development and climate change, energy, water, land and human resources are increasingly under pressure to support societal development and to maintain necessary services. Decision makers need improved tools in order to be better informed about trade-offs and synergies between different development and management choices, and to help them identify options on how to sustainably manage resources. This report proposes a way to carry out a water-energy-food nexus assessment approach in order to: a) understand the interactions between water, energy and food systems in a given context, and b) evaluate the performance of a technical or policy intervention in this given context. The ultimate goal of the nexus assessment is to inform nexus related responses in terms of strategies, policy measures, planning and institutional set-up or interventions.
