The promotion and consumption of indigenous vegetables could help mitigate food insecurity and alleviate malnutrition in developing countries. In this respect, 17 accessions (candidate breeding lines that have not yet officially been released) of five African indigenous vegetables: amaranth (Amaranthus cruentus), nightshade (Solanum scabrum), African eggplant (Solanum aethiopicum), jute mallow (Corchorus olitorius) and okra (Abelmoschus callei), previously selected for their superior agronomic and horticultural traits, were evaluated in Cameroon for minerals (Ca, Mg, K, P, Zn and Fe), proteins, and carotenoids content. Nutrient content differed significantly (P<0.001) between cultivars. Amaranth (especially line AM-NKgn) had the highest Ca, Mg, and Zn content in comparison to other genotypes studied. Nightshade had the highest K and Fe content. The highest K and Fe levels were found in nightshades BG24 and SS52, respectively. Nightshade had the highest level of protein, especially line BFS1. The highest amount of carotenoids was identified in the eggplant variety Oforiwa. The study revealed that these vegetables are important sources of some vital nutrients. Increased production and consumption of these nutrient-rich vegetables will help reduce the nutrition-related disorders in Africa.

Background: Food insecurity is a worrying challenge worldwide, with sub-Sahara Africa most affected. Literature reveals that in developing countries, food insecurity is a largely ''managed process'' , meaning people are active participants in responding to the risks they face in life. This paper focuses on how households cope with food shortages and how these food coping strategies vary along the urban-rural continuum. A transect approach was used to guide data collection in and around the city of Tamale in northern Ghana. A total of 19 Focus Group discussions, having eight participants each (four women, four men), were conducted between March and May 2014. Additionally, three qualitative in-depth interviews were also conducted, one each in the urban, periurban and rural area. Results:In periurban and rural areas, gathering of wild food and selling of charcoal was widely practised, while in urban areas, most households tended to reduce the number of meals as a more frequent coping strategy. The study identified five coping strategies along the urban-rural continuum as the most severe in times of food insecurity, namely skipping a whole day without food, borrowing, buying food on credit, consuming seed stock and restricting adult intake in favour of children. Hunting, consuming less preferred food, taking occasional jobs and engaging in small trading were considered as not severe. Conclusions:Study results reveal that food coping strategies vary from one spatial entity to another in terms of frequency, severity and coping strategy indices along the urban-rural continuum. This information is useful for indicators to predict crisis (early warning), to understand shortfalls in access to adequate food (assessment), to allocate resources (targeting) or to track the impact of interventions (monitoring and evaluation).

Fostering better access to more nutritious foods across sub-Saharan Africa will be critical to ending hunger and malnutrition. In Asia, vegetable production and consumption have grown rapidly since the 1990s and the development of a dynamic vegetable seed industry, led by the private sector, played a pivotal role in this process. The availability of locally-bred and adapted varieties facilitated the rapid expansion of production and increased the supply of affordable vegetables to consumers. In contrast, the vegetable seed sector in sub-Saharan Africa has been slow to develop and has received little attention in the development agenda. Drawing from Asia’s experience, this paper outlines a four-point strategy to accelerate the vegetable seed sector in sub-Saharan Africa. First, there is a need to strengthen the technical capacity of African seed companies to allow them to develop varieties that are well-adapted to local conditions and consumer preferences. Second, seed regulations, originally designed with food grains in mind, should be reviewed and revised to facilitate domestic vegetable breeding research and seed production. Third, more farmer extension is needed to exploit improved varieties together with good management practices. Fourth, vegetable marketing systems should be strengthened to reduce risks to farmers and traders. Investment in these four areas will help energize private sector investment in the vegetable seed sector. Asian experience suggests that investment in locally adapted vegetable varieties is a critical step in improving productivity, availability and ultimately consumption of nutritious vegetables.
