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 Fundamentals of Smallholder Irrigation written by B. Albinson and published by IWMI. This book was released on 2002 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smallholder irrigation systems–where farm sizes generally range from a fraction of a hectare to 10 hectares–pose special management problems, especially where the water available for irrigation is frequently less than the demand. The intensity of system adjustments required to meet individual farmer demands, and the administrative complexity of measuring and accounting water deliveries have generally proven excessive when attempting to meet “on demand†schedules, resulting in chaos (often characterized by illegal tampering with infrastructure, and vast differences of water use intensity at different locations in the system). The alternative–provision of a simple service, based on proportional sharing of available supplies on the basis of landholdings–has been resilient for many years over vast areas. The approach is based on a clear delineation between the part of the irrigation system that is actively managed (at various flow rates and water levels) and the part of the system that operates either at full supply level (with proportional division of water down to the level at which farmers rotate among their individual farms), or is completely shut. This operational design is known as a “structured†system, and has well-defined hydraulic characteristics, simplifying operation and management, in turn allowing a clearer definition of water entitlements and the responsibilities of agency staff and farmers. The approach is particularly suited to areas where water is scarce and discipline is needed to ration water among users. An additional benefit, which has been demonstrated in modeling studies using a well–proven model relating to water and yield, is that the productivity of water (which is more important than the more traditional productivity of land when water is scarce) is substantially increased when deficit irrigation is practiced–a widely observed and predictable response to rationed water supplies. Structured systems are most suited where water is scarce, clear definition of water entitlements is needed, management capacity is limited, and investment resources are limited. The approach to determining critical aspects of a structured system design is described in this report.

Available in PDF, EPUB and Kindle. Book excerpt: Organic agriculture is defined as an environmentally and socially sensitive food supply system. This publication considers the contribution of organic agriculture to ecological health, international markets and local food security. It contains a number of case studies of the practical experiences of small farmers throughout the world (including India, Iran, Thailand, Uganda and Brazil) who have adopted fully integrated food systems, and analyses the prospects for a wider adoption of organic agriculture. The book also discusses the weakness of institutional support for nurturing existing knowledge and exchange in organic agriculture.

Available in PDF, EPUB and Kindle. Book excerpt: Initially associated with hi-tech irrigated agriculture, drip irrigation is now being used by a much wider range of farmers in emerging and developing countries. This book documents the enthusiasm, spread and use of drip irrigation systems by smallholders but also some disappointments and disillusion faced in the global South. It explores and explains under which conditions it works, for whom and with what effects. The book deals with drip irrigation 'behind the scenes', showcasing what largely remain 'untold stories'. Most research on drip irrigation use plot-level studies to demonstrate the technology’s ability to save water or improve efficiencies and use a narrow and rather prescriptive engineering or economic language. They tend to be grounded in a firm belief in the technology and focus on the identification of ways to improve or better realize its potential. The technology also figures prominently in poverty alleviation or agricultural modernization narratives, figuring as a tool to help smallholders become more innovative, entrepreneurial and business minded. Instead of focusing on its potential, this book looks at drip irrigation-in-use, making sense of what it does from the perspectives of the farmers who use it, and of the development workers and agencies, policymakers, private companies, local craftsmen, engineers, extension agents or researchers who engage with it for a diversity of reasons and to realize a multiplicity of objectives. While anchored in a sound engineering understanding of the design and operating principles of the technology, the book extends the analysis beyond engineering and hydraulics to understand drip irrigation as a sociotechnical phenomenon that not only changes the way water is supplied to crops but also transforms agricultural farming systems and even how society is organized. The book provides field evidence from a diversity of interdisciplinary case studies in sub-Saharan Africa, the Mediterranean, Latin America, and South Asia, thus revealing some of the untold stories of drip irrigation.

Available in PDF, EPUB and Kindle. Book excerpt: Good management of water resources - universally identified as a key aspect of poverty reduction, agriculture and food security - has proven, in practice, as difficult to achieve as it is eagerly sought. This book, edited and authored by leading authorities on water resource management, examines the recent changes in governance, institutions, economics and policies of water, covering developing, transitional and developed countries, with special emphasis on southern African case studies. The book examines how water policies, institutions and governance have shifted in recent years from supply-driven, quantitative, centrally controlled management to more demand-sensitive, decentralized, participatory approaches. Such a move often also implies cost recovery principles, resource allocation among competing sectors, and privatization. The case studies demonstrate that the new policies and legal frameworks have been difficult to implement and often fall short of initial expectations. Using an accessible multidisciplinary approach that integrates economics, sociology, geography and policy analysis, the book untangles the issues and presents best practices for policy- and decision-makers, governments and regulators, NGOs and user groups, service providers, and researchers. The overall aim is to show how good water governance structures can be developed and implemented for the benefit of all.
