In the early 1990s scientists in sub-Saharan Africa noted a decline in the presence of traditional African Leafy Vegetables (ALVs) in meals and fields alike. Bioversity International, alarmed by the potential loss of agricultural biodiversity, assembled a broad partnership that, in two successive projects, resulted in a resurgence of interest in ALVs among farmers, researchers and consumers. The area planted to ALVs increased by 80% in some areas and most households growing ALVs reported increases in income. Women were the main beneficiaries, retaining the earnings from ALVs in 80% of households. Among consumers, more families were eating more ALVs more often at the end of the project than at the start.
Lessons Learned
Problem
Traditionally, ALVs formed an important component of the diet for rural and urban dwellers. They are cheap, and thus affordable, and also rich in micronutrients that are lacking in imported vegetables and simplified urban diets, and hence important for nutrition. Despite these benefits, more recently ALVs have been ignored by researchers and avoided by consumers. Researchers ignored them because so many species are involved, use can be very local, and they are often wild or weedy rather than well-behaved horticultural crops. Consumers avoided them because they were associated with poverty and low status, and those available in the market were unappealing and of poor quality. Bioversity reasoned that increased use would not only maintain genetic diversity but also deliver improved nutrition and livelihoods.
Agricultural biodiversity
More than 200 species of ALVs have been recorded as food ingredients in Kenya alone. A first phase of the project gathered data on many of these and worked with communities to identify a subset of priority species for further development. These were amaranth (Amaranthus spp), spider plant (aka cat’s whiskers, Cleome gynandra), molokhia (Corchorus olitorius, the jute plant), pumpkin leaves (Cucurbita spp), African nightshade (Solanum spp), nettles (Urtica massaica) and cowpea (Vigna unguiculata).
The Project
Beginning in 1996, in five countries (Botswana, Cameroon, Kenya, Senegal and Zimbabwe), Bioversity International coordinated local research partners as they explored and collected the ALV in their region, investigated their nutritional profile and role in the diet and tried to understand the farming and marketing challenges they presented. The information gained in this phase allowed the partners to decide on the eight priority species (see above), which would be the basis of a second phase to improve the nutrition and food security of women and children, as particularly vulnerable groups. Achieving this overall goal would require increasing production, sales and consumption of the priority species, which in turn would result in increased conservation on farms and in genebanks.
The second phase of the project brought together many partners with specialist interests. Farm Concern, an NGO, contributed to training and linked farmers to markets. One of those, Uchumi Supermarkets, worked with farmers to improve quality and consistency of their produce and to strengthen supply chains. Many organisations contributed to successful publicity campaigns that raised the profile of ALV and informed households how to add them to their meals.
Impact
The effect of the project can be seen in several measures.
Further opportunities
It would be useful to quantify directly the impacts of eating more ALVs on nutrition and health. Publicity campaigns were very effective in driving up consumption of ALVs and offer opportunities for more focused efforts, for example targeted at expectant mothers and their babies. Rural dwellers remain less aware than urban dwellers of the benefits of ALVs.
