This study considers existing off-grid initiatives that are being implemented in support of more rapid electrification in sub-Saharan Africa. After first reviewing the successes and obstacles of commonly implemented off-grid solutions, we suggest groundwater irrigation powered via off-grid solar (OGS) systems as a productivity-focused electrification solution that could be valuable to off-grid development initiatives moving forward. This solution encourages the establishment of OGS pumping infrastructure in unelectrified areas in proximity to nonirrigated agriculture that have promising and sustainable groundwater abstraction potential. Using open-access spatial data to estimate the alignment of these resources is an important first step in determining potential study sites for on-the-ground research and pilot projects. This study focuses on applying the above approach to Ethiopia to produce a spatial layer representing areas that are recommended for further assessment of their OGS groundwater irrigation viability. We follow the spatial analysis with a projection of potential gains from investment in OGS groundwater pumping systems under different scenarios to highlight the solution’s viability with regional context. This assessment provides an initial methodology for identifying, examining, and expanding upon potential markets where OGS irrigation can become an economically viable solution.

This open access book presents the proceedings of the 2nd Africa-EU Renewable Energy Research and Innovation Symposium (RERIS 18), held in Maseru, Lesotho in January 2018. The symposium aimed to foster research cooperation on renewable energy between Africa and Europe – in academia, as well as the private and public sectors. Addressing thematic areas such as • Grid-connected renewable energy; • Decentralised renewable and household energy solutions; • Energy socioeconomics; and • Promotion of energy research, innovation, education and entrepreneurship, the book brings together contributions from academics and practitioners from the EU and Africa to enable mutual learning and knowledge transfer – a key factor in boosting sustainable development in the African renewable energy market. It also plays a significant role in promoting African renewable energy research, which helps to secure energy supply in both rural and urban areas and to increase generation capacities and energy system resilience. This book is an invaluable resource for academics and professionals across the renewable energy spectrum.

Increasing the efficiency of water use and enhancing agricultural water productivity at all levels of the production chains are becoming priorities in a growing number of countries. In particular, shifting to modern on-farm irrigation practices can contribute to a substantial increase in both water use efficiency and water productivity. The objective of this handbook is to provide a practical guide on the use of pressurized irrigation techniques to farmers, irrigation technicians, and extension workers in the field. In this second edition, the handbook has been considerably revised, including new chapters on low-cost drip irrigation and pipe distribution systems for smallholders.--Publisher's description.

In 2021, the United Nations Secretary-General will convene the Food Systems Summit to advance dialogue and action towards transforming the way the world produces, consumes and thinks about food guided by the overarching vision of a fairer, more sustainable world. The Secretary-General will also convene the High-Level Dialogue on Energy (HLDE) to promote the implementation of the energy-related goals and targets of the 2030 Agenda for Sustainable Development. Given the inextricable linkages between the energy and agriculture sectors, integrating the nexus perspective within the FSS and the HLDE is crucial to formulate a joint vision of actions to advance the 2030 Agenda for Sustainable Development and the Paris Agreement. In this context, IRENA and FAO have decided to jointly develop a report on the role of renewable energy used in food chain to advance energy and food security as well as climate action towards the achievement of Sustainable Development Goals and the Paris Agreement. While energy has a key enabling role in food system transformation and innovation in agriculture, its current use is unsustainable because of the high dependence on fossil fuels and frequent access to energy in developing countries. The challenge is to disconnect fossil fuel use from food system transformation without hampering food security. The use of renewable energy in food systems offers vast opportunities to address this challenge and help food systems meet their energy needs while advancing rural development while contributing to rural development and climate action.

Solar power for pumping groundwater has a vast potential for improving the sustainability of water supply schemes. However experience also shows that a lack of knowledge, capacity and expertise to design and implement such schemes is holding back their adoption. This book bridges this gap to equip engineers and technicians with the requisite knowledge for design, implementation and operation of sustainable solar powered water schemes.Solar Pumping for Water Supply is a state of the art review of solar water pumping technology combined with practical insights, lessons and best practices drawn from experience. It takes the reader step by step through the different phases that comprise a solar water pumping project, namely: assessment, design, purchase of equipment, installation, operation and management. The book also covers the economics of using solar pumping technology, especially when compared to diesel generators and hand pumps. Finally, the social aspects are included, specifically relating to the operation and management of solar pumping systems and the role that beneficiaries, implementers, government and the private sector might play to ensure long-lasting water supply. The book provides links and references to tools, documents and videos to accompany the content of the different chapters.Essential reading for solar technical practitioners at NGOs, UN agencies, government offices and private sector, including Global and Regional Technical advisors and Field engineers wanting to understand and know how to design water systems using solar power. A basic knowledge in the field of water supply is assumed, but no previous knowledge of solar photovoltaic technology is required.Alberto Ibáñez Llario is a Global Solar and Water Advisor with the International Organization for Migration and has 15 years of experience in water systems and solar PV in various locations around the world.Asenath Kiprono is a solar water pumping expert with 12 years' experience in design and implementation of pumping systems in rural Africa, including solar pumping systems in the private, public and humanitarian sectors.

This open access book discusses the current role of smallholders in connection with food security and poverty reduction in developing countries. It addresses the opportunities they enjoy, and the constraints they face, by analysing the availability, access to and utilization of production factors. Due to the relevance of smallholder farms, enhancing their production capacities and economic and social resilience could produce positive impacts on food security and nutrition at a number of levels. In addition to the role of small farmers as food suppliers, the book considers their role as consumers and their level of nutrition security. It investigates the link between agriculture and nutrition in order to better understand how agriculture affects human health and dietary patterns. Given the importance of smallholdings, strategies to increase their productivity are essential to improving food and nutrition security, as well as food diversity.
