Smallholder irrigation schemes in the Limpopo Province, South Africa
A survey of 76 public smallholder irrigation schemes in the Limpopo Province was jointly conducted by the International Water Management Institute (IWMI), Department of Agriculture, Forestry and Fisheries (DAFF), South Africa, and the Limpopo Department of Agriculture and Rural Development (LDARD), as part of the ‘Revitalization of Smallholder Irrigation in South Africa’ project. About one-third of those schemes was fully utilized; one-third partially utilized; and one-third not utilized in the winter of 2015; however, no single socioeconomic, physical, agronomic and marketing variable could explain these differences in utilization. Sale, mostly for informal markets, appeared the most important goal. Dilapidated infrastructure was the most important constraint cited by the farmers. The study recommends ways to overcome the build-neglect-rebuild syndrome, and to learn lessons from informal irrigation, which covers an area three to four times as large as public irrigation schemes in the province.

Climate Change Science
Climate Change Science: Causes, Effects and Solutions for Global Warming presents unbiased, state-of-the-art, scientific knowledge on climate change and engineering solutions for mitigation. The book expands on all major prospective solutions for tackling climate change in a complete manner. It comprehensively explains the variety of climate solutions currently available, including the remaining challenges associated with each. Effective, complementary solutions for engineering to combat climate change are discussed and elaborated on. Some of the more high-risk proposals are qualitatively and quantitatively compared and contrasted with low-risk mitigation actions to facilitate the formulatio...
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...
Landscapes between Then and Now
In Landscapes Between Then and Now, Nicola Brandt examines the increasingly compelling and diverse cross-disciplinary work of photographers and artists made during the transition from apartheid to post-apartheid and into the contemporary era. By examining specific artworks made in South Africa, Namibia and Angola, Brandt sheds light on established and emerging themes related to aftermath landscapes, embodied histories, (un)belonging, spirituality and memorialization. She shows how landscape and identity are mutually constituted, and profiles this process against the background of the legacy of the acutely racially divisive policies of the apartheid regime that are still reflected on the land...
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 �...
Towards Sustainable Food Production in Africa
This edited book is focused on Sustainable Development Goal 2. It offers a comprehensive and topical collection of practices, technologies and innovations in the field of sustainable food production and security under a changing climate. It is a one-stop handbook for farmers, researchers, extensionists, policy makers and other stakeholders seeking to identify and disseminate best fit technologies for local and regional landscapes. It offers an understanding of the challenges, risks and uncertainties as well as opportunities to foster productive and sustainable food production. Smallholder farming and agriculture in general is facing a serious threat from climate change that has resulted in e...
