“…The global market of vegetables is still predominantly local because only about 5% of vegetables grown worldwide are marketed internationally [50] (Sumalan et al, 2021). According to Sumalan et al [50] "the total volume of exports of vegetables reached at 47 million tonnes with a value of 42.3 billion US$ in 2018." In the same year, 64% of total vegetable exports were contributed by Netherlands (6.1 million tonnes), Mexico (5.8 million tonnes), Spain (5.1 million tonnes), China (4.3 million tonnes), France (3.5 million tonnes), Germany (2.7 million tonnes) and the United States (2.4 million tonnes).…”

“…Consumers in many parts of the world derive a major portion of their diets from vegetables of which 70% are sold as fresh (unprocessed) hortcultural products [50]. Traditional African Vegetables (TAVs) are an affordable and relatively inexpensive source of vitamins, essential minerals, dietary fibber, and various phytochemicals which have a role in reduction of malnutrition, stunting growth and poor health among consumers in different areas of Sub-Saharan Africa.…”

“…The gene bank is a reservoir of biodiversity that acts as a source of genes which are used in breeding programs [50]. The World Vegetable Center (WorldVeg) genebank of traditional African vegetables currently has 2500 accessions which originated from germ-plasm-collecting mission with national partners across Africa in early 2000s [55].…”

The agricultural sector is challenged to fulfill the nutritional requirements of ever-increasing population. Rates of growth in crop productivity have declined, among many reasons is due to climate change and the decline of water and land resources. Dependence by 50% on few cereal crops like wheat, maize and rice for total food intake and calorie requirements has countersigned loss of biodiversity and decline in crop productivity. The genetic diversity of traditional crop varieties offers resilience to environmental risks, socioeconomic shocks, adaptation and mitigation to climate change which is crucial for crop production. Traditional African Vegetables (TAVs) are an integral constituent of the diets of many rural and urban communities. They are important sources of essential macro and micro-nutrients. In addition, they offer a source of livelihood when marketed, and also contribute to crop biodiversity. Tanzania needs to conserve the Traditional African vegetables and their genetic resources against stressful conditions and increased selection pressures which causes loss of genetic variation and a decrease in fitness by a process called genetic erosion. Conservation and use alleviate genetic drift and inbreeding depression, then, is critical to guarantee TAVs persistence in rural areas. This review explores agrobiodiversity of traditional African vegetables (TAV) from livelihood of Tanzanian rural communities’ perspectives and how the country has managed to conserve these species.

Compensation for custodian farmers to provide agrobiodiversity-conservation services in their farms (in situ) is an emerging global approach because it can generate public benefits when it comes to important plant genetic resources (PGRs) for food and agriculture. This review focused on: i) the integration of in situ conservation to the PGR management involving custodian farmers in a systematic conservation approach; ii) the private benefits obtained by custodian farmers to increase their willingness to actively participate in the conservation service; and iii) the willingness to accept (WTA) compensation of the farmers in providing conservation service relative to opportunity costs. The most recent approaches suggest the integration of in situ conservation with ex situ conservation management for efficient conservation programmes, especially in relation to governance of local agrobiodiversity. Involving custodian farmers in the comprehensive genetic-improvement system appears to be an activity that increases their willingness to participate in agrobiodiversity conservation schemes. Farmers receive private benefits, which are simultaneously reflected in the provision of public benefits. Therefore, WTA compensation, which employs mechanisms in the design of payments for better agro-environmental conservation services, controls the opportunity costs. Overall, farmers seem willing to participate in any type of compensation scheme that is proposed in the different countries. Furthermore, it is possible to capture the WTA, therefore significant progress requires more studies of primary schemes, indepth analysis to capture farmers' preferences on economic, socio-cultural, and environmental factors in scheme design, and the implementation of incentive policies designed with pragmatic tools.
