Is irrigation fit for purpose? A review of the relationships between scheme size and performance of irrigation systems
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 â...
Engineering for Sustainable Development and Living
What can we do to preserve a future for the next generation to cherish? A potent answer is to exercise good stewardship in realizing more sustainable living and development. This volume brings together experts from around the world to disseminate the latest knowledge and research toward this end, i.e., engineering for more sustainable development and living. Let us learn from a living cell that utilizes inherited biological intelligence to organize its resources for current needs and future existence. We also have the responsibility to ensure universal access to electricity and increase the share of renewable energies. Cost effective hybrid renewable energy systems should also be considered ...
Advances in water research
Water scarcity has become one of the greatest challenges facing humankind today. Its scarcity is compounded by climate change and increasing demand from a growing population. In South Africa, over 60% of the available freshwater resources are used in agriculture, mainly in irrigated agriculture. There is an urgent need to promote sustainable irrigation technologies that optimize food production without increasing water applied and with positive environmental spinoffs. Sustainable irrigation technologies and practices could enhance water use efficiency (WUE) and productivity in agriculture and reduce environmental burdens, including energy use. This chapter highlights some of the innovative i...

Progress in Sustainable Development: Sustainable Engineering Practices provides readers with the latest research and best practices in sustainable engineering in the fields of urban, environmental, energy and sustainability sciences, reflecting a focus on state-of-the art insights and the latest developments. Chapters focus on the key engineering principles of effective resource use, reduction of excess waste, and taking advantage of natural resources to equip readers with the background information and practical considerations of successful implementations of sustainable technical solutions. Each chapter features detailed case studies and figures showing real-world applications of the lates...
Mapping irrigated areas in the Limpopo Province, South Africa
This report summarizes the findings of a collaborative effort to map and assess irrigated areas in the Limpopo Province, South Africa. The study was conducted by the International Water Management Institute (IWMI) in collaboration with the Department of Agriculture, Forestry and Fisheries (DAFF) and the Limpopo Department of Agriculture and Rural Development (LDARD), as part of the DAFF-supported ‘Revitalization of irrigation in South Africa’ project. Based on a combination of Landsat and Moderate Resolution Imaging Spectroradiometer (MODIS) satellite data, previous irrigated area mapping exercises carried out by DAFF and three-field ground truthing (GT) surveys, a total of 1.6 million hectares (Mha) of cropland were identified, with 262,000 ha actually irrigated in the 2015 winter season. The study also found that only 29% of all land equipped with center pivots was actually irrigated.
