Download or read book Sustainable Water Management in Smallholder Farming written by Sara Finley and published by CABI. This book was released on 2016-07-27 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
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'.

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 Biofuels written by Ayhan Demirbas and published by Springer Science & Business Media. This book was released on 2008-11-14 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biofuel is a renewable energy source produced from natural materials. The benefits of biofuels over traditional petroleum fuels include greater energy security, reduced environmental impact, foreign exchange savings, and socioeconomic issues related to the rural sector. The most common biofuels are produced from classic food crops that require high-quality agricultural land for growth. However, bioethanol can be produced from plentiful, domestic, cellulosic biomass resources such as herbaceous and woody plants, agricultural and forestry residues, and a large portion of municipal and industrial solid waste streams. There is also a growing interest in the use of vegetable oils for making biodiesel. “Biofuels: Securing the Planet’s Future Energy Needs” discusses the production of transportation fuels from biomass (such as wood, straw and even household waste) by Fischer-Tropsch synthesis. The book is an important text for students and researchers in energy engineering, as well as professional fuel engineers.

This book was released on 2022-08-16 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: CHECK DAM CONSTRUCTION FOR SUSTAINABLE WATERSHED MANAGEMENT AND PLANNING Authoritative and comprehensive reference on the potential for watershed development through the use of check dams Check Dam Construction for Sustainable Watershed Management and Planning summarizes current knowledge of check dams as key soil and water conservation structures in some of the most sensitive and vulnerable ecosystems in the world, as exemplified by the Mediterranean area and the Chinese Loess Plateau, providing detailed information on check dam design and watershed planning, the use of advanced modeling techniques, challenges in dam construction and how to overcome them. The work integrates decades of research in the field of soil and water conservation and gully management, including advanced studies in check dam construction and watershed management. It also covers important new techniques and methods, such as hydrological modeling, isotope tracing, and more. To aid in reader comprehension, the five highly qualified editors have divided the work into three distinct sections. Sections I and II focus on the experience gained from the erosion hotspots in the Chinese Loess Plateau, whereas Section III expands the scope to other regions with different functions for check dams, including headwater ecosystems and alpine environments. Sample topics covered in Check Dam Construction for Sustainable Watershed Management and Planning include: The regulating effect of check dam systems on sediment redistribution and the formation and development of dam systems in small watersheds Water and soil conservation made possible by check dam construction and sediment source analysis of water-sediment retarding effects of check dams The regulation of check dam systems on the erosion dynamic process and the mechanism of erosion reduction by check dams Flood control risk assessment on warping dam systems and the development and utilization model of check dam systems With its systematic coverage of all aspects of dam construction and maintenance, Check Dam Construction for Sustainable Watershed Management and Planning supports decision making by local authorities and can also be used as a professional guide for ecologists, hydrologists, and water resource managers.

Available in PDF, EPUB and Kindle. Book excerpt: Modeling aspects have added a new dimension in research innovations in all branches of engineering. In the field of soil and water engineering, they are increasingly used for planning, development, and management of land and water resources, including analysis of quantity and quality parameters of surface and ground water, flood forecasting and control measures, optimum allocation and utilization of irrigation water. The application of these models saves considerable time in decision support systems and helps in conservation and optimum allocations of scarce precious natural resources.

Download or read book Water Technology in the Middle Ages written by Roberta J. Magnusson and published by JHU Press. This book was released on 2001-12-04 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Focusing attention on gravity-fed water-flow systems in medieval cities and monasteries, Water Technology in the Middle Ages: Cities, Monasteries, and Waterworks after the Roman Empire challenges the view that hydraulic engineering died with the Romans and remained moribund until the Renaissance. Roberta Magnusson explores the systems' technologies -- how they worked, what uses the water served -- and also the social rifts that created struggles over access to this basic necessity. Mindful of theoretical questions about what hastens technological change and how society and technology mutually influence one another, the author supplies a thoughtful and instructive study. Archeological, historical, and literary evidence vividly depicts those who designed, constructed, and used medieval water systems and demonstrates a shift from a public-administrative to a private-innovative framework -- one that argues for the importance of local initiatives. "The following chapters attempt to chart a course between the Scylla and Charybdis of technological and social determinism. While writing them, I have tried to strike a balance between the technical and human aspects of medieval hydraulic systems, and to remember that beneath the welter of documents and diffusion patterns, configurations and components, ordinances and expenditures, lie the perceptions, the choices, and often the plain hard work of individual men and women." -- from the Preface
