This report is the second in a series of three evaluating underexploited African plant resources that could help broaden and secure Africa's food supply. The volume describes the characteristics of 18 little-known indigenous African vegetables (including tubers and legumes) that have potential as food- and cash-crops but are typically overlooked by scientists and policymakers and in the world at large. The book assesses the potential of each vegetable to help overcome malnutrition, boost food security, foster rural development, and create sustainable landcare in Africa. Each species is described in a separate chapter, based on information gathered from and verified by a pool of experts throughout the world. Volume I describes African grains and Volume III African fruits.

Supply chains for nutritious (“protective”) foods in Africa south of the Sahara are often poorly developed, especially for perishable crops that are vulnerable to wastage. We used LSMS-ISA surveys and geographic information system (GIS) data to explore which factors predict production patterns of four protective food crops (pulses, nuts and seeds, vegetables, and fruits) relative to cereals and starchy roots and tubers (grouped under staples) in Ethiopia, Malawi, Tanzania, and Uganda, with a focus on potential inter-ventions to improve production, trade, and consumption of these foods. Plot-level irrigation adoption is the strongest predictor of fruit and vegetable production, along with precipitation, suggesting that water availability is a major precondition for pro-ducing these protective foods. In contrast, pulses and nuts and seeds can be grown in drier and warmer conditions. Better market access is also associated with higher production of fruits and vegetables, but the association is weaker than that of water access. Investing in and expanding irrigation-especially small-scale irrigation-has strong poten-tial to yield high returns in East Africa, especially for poor households that cannot afford to invest in capital-intensive irrigation technologies. Irrigation investments may need to be complemented by investments in roads, rural elec-trification, and cold storage chains to promote efficiency of postharvest supply chains and reduce marketing costs.

This book will convince the reader to care about fruit and vegetables and to see that the small-scale production of these crops is fundamental to achieving sustainable development goals. In five chapters, the reader will learn about the challenges and rewards for producers, sellers, and consumers. Chapter 1: a working definition for fruit and vegetables, making the case for supporting small-scale farmers and value chains. Chapter 2: options for farm management to ensure that production is sustainable including genetic resources, seed systems, management of water, soil, nutrients, and control of pests and diseases. Chapter 3: options to integrate small-scale commercial fruit and vegetable farmers into socially inclusive value chains, including innovative post-harvest handling services, market linkages, and reducing food loss and waste. Chapter 4: options for practitioners and policymakers at different governmental, institutional and social levels to promote the sustainable production and consumption of safe, nutritious, and affordable fruit and vegetables. Chapter 5: key interventions and innovations to facilitate the sustainable production of fruit and vegetables in low- and middle-income countries across the world. This publication takes readers on a journey introducing them to a diverse array of fruit and vegetables through colorfully illustrated studies from around the world. It justifies the importance of these crops and it encourages readers to take an active role both in promoting fruit and vegetable production and in encouraging more people to eat them.

This book provides a comprehensive synthesis of current knowledge of the potential and challenges associated with the multiple roles, use, management and livelihood contributions of indigenous vegetables in urban agriculture in sub-Saharan Africa. There has been growing research and policy effort around urban agriculture in the region over the last two decades, but never has it been integrated with work on under-researched crops such as indigenous vegetables. These species have multiple advantages, including low input requirements, adaptability to African environments, high nutritional value and marked biodiversity, cultural and local food security significance. Yet they are overlooked in the modern world, where recent emphasis has been directed to growing a limited range of exotic crops, both for internal markets and for export to developed country markets. This book provides evidence that, in spite of this neglect, in many African cities indigenous vegetables are still widely used, cultivated and marketed. It goes on to consider their potential to contribute to income generation and poverty alleviation of the growing numbers of urban dwellers in sub-Saharan Africa, whilst promoting urban greening and sustainability. Based on critical analysis of the debates it presents a multidisciplinary analysis of the realities and future opportunities.

Food Crop Production by Smallholder Farmers in Southern Africa: Challenges and Opportunities for Improvement evaluates traditional cultivation practices used by smallholder farmers, providing a synthesis of the latest information on increasing crop yield through adoption of research innovations. The book catalogs smallholder cultivation practices and recommends innovative strategies for improving the agriculture sector including: management practices that reduce net carbon emissions; technologies that improve soil structures and conserve the natural resources base; means of empowering female resources along value chains; and government commitment to adopt policies that enhance agriculture productivity by encouraging farmers to use environmentally sound cultivation technologies. Traditional farming techniques often produce negative impacts on the environment and ecosystem resulting in outbreaks of diseases and pests. In addition to the region’s recurrent droughts, these outbreaks of numerous diseases and pests, weeds and other invasive plants put thousands at risk of poverty and hunger, as well as malnutrition. This book presents enhanced agricultural production technologies for ensuring adequate food production, safety and nutritional quality for the population of Southern Africa and forms the basis for an increased SADC regional effort in food production through which financial and trade institutions can improve stakeholder capacities, encourage micro-enterprise development and enhance employment and regional trade. Provides a critical synthesis of data and information for increasing crop yield through adoption of research innovations Evaluates traditional and scientific interventions that address food security issues of the poor farmers in the region Presents agro-ecologies of countries in the region and how they relate to various cultivation practices Catalogs smallholder cultivation practices and recommends innovative strategies for improving the agriculture sector
