Mapping irrigated areas in the Limpopo Province, South Africa by Cai, Xueliang,Magidi, J.,Nhamo, Luxon,van Koppen, Barbara Pdf

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.

Smallholder irrigation schemes in the Limpopo Province, South Africa by van Koppen, Barbara,Nhamo, Luxon,Cai, Xueliang,Gabriel, M. J.,Sekgala, M.,Shikwambana, S.,Tshikolomo, K.,Nevhutanda, S.,Matlala, B.,Manyama, D. Pdf

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.

Advances in water research by Nhamo, L.,Mpandeli, S.,Liphadzi, S.,Hlophe-Ginindza, S.,Kapari, M.,Molwantwa, J.,Mabhaudhi, Tafadzwanashe Pdf

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 irrigation practices and technologies that enhance food production and, at the same time, reduce water use in agriculture. The chapter broadly discusses WUE and water productivity (WP) in irrigated agriculture from engineering and agronomic perspectives. The chapter further highlights some of the environmental impacts of irrigation expansion and the possible solutions. We further provide the importance of accurate spatial information on irrigated areas to inform policy on irrigation expansion. The Water Research Commission (WRC) of South Africa has been spearheading research on the sustainable use of water for the past 50 years as part of its research agenda. In Ting, D. S.-K.; O’Brien, P.

Towards Sustainable Food Production in Africa by Morris Fanadzo,Nothando Dunjana,Hupenyu Allan Mupambwa,Ernest Dube Pdf

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 erratic and unpredictable rainfall and increased temperatures, among other abiotic stresses. These climate change induced pressures have reduced productivity mainly among the smallholder farmers, who are critical in driving the attainment of sustainable development goals like SDG 2, 12 and 13. The objective of the book is to document effective and practicable practices and technologies that can be adopted by smallholder African farmers as mitigation measures against the effects of climate change. This book is of interest to researchers, agricultural scientists, climate change scientists, capacity builders and policymakers.

The Oxford Handbook of Food, Water and Society by Tony Allan,Brendan Bromwich,Martin Keulertz,Anthony Colman Pdf

Food, water and society: what is managed by whom, and with what impacts? Our food supply chains are at risk. Water resources--sometimes scarce, often damaged, and always under-valued--are among the major reasons why food and water security rank high every year in the World Economic Forum's major global risk analysis. A stable and sustainable food system is critical to society's survival. This Handbook shows that keeping the food system stable comes at the expense of the environment, especially of water resources and those who consume and manage them. The way the food system operates reflects hard political realities. Rather than pay for the environmental costs of sustainable production, society expects food at ever lower prices. Governments reflect their electorates in this regard. Given that farm production may account for as little as 10% of the food value chain in wealthy economies, it is striking that governments have been unwilling (or unable) to put in place the essential laws and accountability that would enable famers to ensure both production and stewardship. Corporate food traders, food manufacturers, and retailers on the other hand operate in markets that make profits and pay taxes. But these corporations are not contractually bound to utilize highly nutritious, sustainably produced food commodities. The articles in this Oxford Handbook have been written by water and food system scientists and professionals, including farmers, rarely heard voices who understand the problems of food producers, food manufacturers, and regulating markets and public policy. The articles address the blind spots of society and its public policymakers, demonstrating the importance of informing society about the consequences of its food preferences and the heroic challenges it is beginning to face. The damage we are doing to our water and soil ecosystems is as important as the damage we do to the atmosphere. Impressed by the technical and organizational advances of the past two centuries, the contributors featured in this book also take note of where economic inefficiencies and cultural deadlock in a 4,000 year old system are putting our critical food supply chains at risk.

The Bioeconomy Approach by Udaya Sekhar Nagothu Pdf

This book examines the bioeconomy concept, analysing the opportunities it can generate, the constraints and the potential benefits for society. The main objective of bioeconomy is to promote economic development, by creating jobs and enhancing the sustainable utilization of bio-resources. A primary driver of bioeconomy strategy, therefore, is the need to respond to the growing population's food and economic requirements. While today research and literature related to bioeconomy are limited, this book presents a unique collection of perspectives on the complex dimensions of the bioeconomy debate. Drawing on the experiences from Europe, Asia and Africa, it presents an international overview. The chapters address a wide range of issues, including coastal-land interactions, ecosystem services, food production, rural development, agriculture, forest management and bioenergy. As a whole, the volume outlines what role bioeconomy can play in contributing to the United Nations Sustainable Development Goals (SDGs) without compromising on the ecological sustainability and equitable distribution of benefits. The book concludes by providing recommendations for developing bioeconomy in respective sectors (agriculture, forestry, fisheries, renewable energy) and directions for planning future bioeconomy programmes and strategies. The Bioeconomy Approach will be of great interest to students and scholars of ecological economics, development economics and environmental economics, as well as policy-makers and practitioners involved in sustainable development.
