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.

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.

Download or read book Water Distribution Within Smallholder Irrigation Schemes in Tanzania and Its Implications for Economic Inequality written by Ana Manero and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates the linkages between water supply and economic inequalities within smallholder irrigation schemes, with particular focus on Tanzania, as a key example of a developing, agrarian economy in sub-Saharan Africa. In developing countries, income inequalities are critical for poverty reduction as they determine how economic growth is distributed and, thus, to which extent the poor benefit relative to everyone else. On a global scale, and in sub-Saharan Africa in particular, poverty is most prevalent in rural areas where agriculture is the main source of livelihoods. Irrigation development is recognised as a key strategy for rural poverty reduction, although a growing body of literature questions its implications for equity and social justice. While this topic is addressed from various perspectives in the literature, there is a gap among empirical studies. Specifically, the linkages between irrigation water supply and economic inequalities at small scales have received limited attention. To research this need, this thesis carries out quantitative, qualitative and policy investigations on two smallholder irrigation schemes in southern Tanzania. The data originates from structured household surveys, semi-structured interviews with key informants, direct infrastructure observations, maps of the irrigation schemes and documentary sources. The thesis is organised as follows: First, inequality analyses using the Gini coefficient and the Theil index are used to calculate the level and decomposition of income inequalities within six smallholder irrigation schemes in sub-Saharan Africa. Next, qualitative investigations uncover irrigators' perspectives about the association between water supply and economic inequalities within the two Tanzanian schemes. Third, multiple regression analyses evaluate the relative impact of water supply and farm location (as well as other variables) on irrigated crop income and production within smallholder irrigation schemes. Finally, an investigation of Tanzania's water and irrigation institutional framework highlights current policy shortfalls and possible strategies targeting greater equity of irrigation water supply. This thesis' findings show that high levels of income inequality exist within agricultural communities in Zimbabwe, Tanzania and Mozambique, and that such disparities are not properly considered by development polices based upon national statistics. In particular, within smallholder irrigation schemes, inequities in water supply affect economic inequalities in multiple ways, some of which - for example erosion of human capital and social stratification - are not adequately noted in previous literature. Household characteristics and farm location are also shown to be important for irrigated crop incomes and yields. While typically regarded as a good water management practice, the transfer of responsibilities to the local level is shown in this study to be problematic for traditional irrigators. Instead, in the pursuit of greater equity of water supply, participatory process should be considered based on six key equity aspects: quantity; reliability; obligations; benefits/externalities; decision-making; and land rights. Overall, this thesis contributes the international development and inequality literature by providing a deeper understanding of: a) the effect of irrigation water supply on economic inequalities; and b) which water policies might be changed to reduce water supply inequities within traditional irrigation systems. These findings are important to respond to rural poverty in Africa, as it is at the local scale that poverty, growth and inequality interventions can be most effective. Importantly, because a large part of the world's rural population seeks pathways out of poverty, it is critical to ensure that income-enhancing strategies, such as irrigation, do not result in aggravated economic disparities and a barrier to sustainable human development.
