Résumé Fruit-based agroforestry holds substantial potential in terms of economic and ecological feasibility and social acceptability and could enhance household food security. With the prospect of contributing to the development of this system, a study was undertaken on fruit species in the wilderness and homegardens to assess their species composition and diversity, state of exploitation and management, cultural domain and local knowledge of people. Data were collected through individual interviews, free-listing, focus group discussions and farm and market fruit inventories. Fruit species diversity appeared higher in the wilderness than in homegardens. Forty-six species make up the wild fruits cultural domain where youngsters have a better knowledge of species than elders. Albeit primarily for non-fruit uses, a low level of wild fruit domestication is in progress, the propensity to which is negatively influenced by a free availability mindset, illiteracy and land shortage. In gardens, species richness is favourably influenced by altitude and gardeners’ training and inversely by distance from market and residence. Tree number is high in large sized and male-headed household gardens and lower in gardens distant from markets. Fruit production lacks access to and use of modern inputs, management and technical support. Soil fertility is maintained high and production is organic. Although fruits are accessible year-round, their current use is low, due to people’s dietary custom, ignorance of nutritional value, cash need and local taboos. Besides, though few wild and all cultivated fruits are marketable, trade flows, prices and incomes appear to be low
