Book Description
Traditionally, indigenous irrigation in many countries of Asia, Africa, and Latin America has been managed quite well by water users, who design, build, operate, and maintain often sophisticated, but usually small-scale, systems. More recently, in connection with large-scale development programs and government-managed schemes, the planned introduct

Book Description
Irrigated agriculture has played a critical role in the economic and social development of the United Statesâ€"but it is also at the root of increasing controversy. How can irrigation best make the transition into an era of increasing water scarcity? In A New Era for Irrigation, experts draw important conclusions about whether irrigation can continue to be the nation's most significant water user, what role the federal government should play, and what the irrigation industry must do to adapt to the conditions of the future. A New Era for Irrigation provides data, examples, and insightful commentary on issues such as: Growing competition for water resources. Developments in technology and science. The role of federal subsidies for crops and water. Uncertainties related to American Indian water rights issues. Concern about environmental problems. And more. The committee identifies broad forces of change and reports on how public and private institutions, scientists and technology experts, and individual irrigators have responded. The report includes detailed case studies from the Great Plains, the Pacific Northwest, California, and Florida, in both the agricultural and turfgrass sectors. The cultural transformation brought about by irrigation may be as profound as the transformation of the landscape. The committee examines major facets of this cultural perspective and explores its place in the future. A New Era for Irrigation explains how irrigation emerged in the nineteenth century, how it met the nation's goals in the twentieth century, and what role it might play in the twenty-first century. It will be important to growers, policymakers, regulators, environmentalists, water and soil scientists, water rights claimants, and interested individuals.

Book Description
Irrigation is increasingly being called upon to help stabilize and grow food and water security in the face of multiple crises; these crises include climate change, but also recent global food and energy price crises, including the 2007/08 food and energy price crises, and the more recent crises triggered by the COVID 19 pandemic and the war on Ukraine. While irrigation development used to focus on public, large-scale, surface- and reservoir-fed systems, over the last several decades, private small-scale investments in groundwater irrigation have grown in importance and are expected to see rapid future growth, particularly in connection with solar-powered pumping systems. But is irrigation ‘fit-for-purpose’ to support population growth, economic development, and multiple food, energy and climate crises? This paper reviews how fit-for-purpose irrigation is with a focus on economies of scale of surface and groundwater systems, and a particular examination of systems in Sub-Saharan Africa where the need for expansion is largest. The review finds challenges for both larger surface and smaller groundwater systems in the face of growing demand for irrigated agriculture and dwindling and less reliable water supplies. To support resilience of the sector, we propose both a holistic design and management improvement agenda for larger surface systems, and a series of suggestions to improve sustainability concerns of groundwater systems

Book Description
This paper analyzes the contributions of a non-goverment organization in improving management of small-scale irrigation systems in Sri Lanka. It documents the decision-making processes in the non-government organization and the context in which this decision making takes place: government policies and policies of non-government organizations in improving the performance of small scale irrigation systems and in assisting the rural population in general. The site selected for research was the Tank Settlement Project in Hamhantota District, Southern Sri Lanka.

Book Description
Small-scale irrigation (SSI) provides great benefits to farmers in terms of increased yields and profits, better food and nutrition security and greater resilience to climate shocks. Ethiopia has high potential for expanding SSI and has invested considerably in this area in recent years. Despite these investments, several challenges to further expansion of irrigation technologies remain. Different stakeholders in the country play important roles in overcoming these barriers to further scale technologies for SSI. This paper explores institutional arrangements for the diffusion of small-scale irrigation technologies by mapping the landscape of key actors involved, their interconnections, and their influence. This paper draws on an analysis of stakeholder data collected through two participatory workshops in Ethiopia, one at the national level and one at the Oromia regional level, using the Net-Map approach. Results show the dominance of government actors in the diffusion of SSI at both the national and regional levels, while most private sector and NGO actors remain in the periphery. Participants in both workshops highlighted the need for increased financing services to support the adoption of SSI and measures aimed at increasing the supply of high-quality irrigation equipment, such as modern water lifting technologies. One notable difference between the national and regional results was that at the regional level, farmers, and to some extent traders and input suppliers, were considered to be more influential in the diffusion of irrigation technologies, while they were considered marginal actors at the national level.
