Résumé
When agriculture becomes focused on globally traded commodities, local nutrition may be at risk. The study tested this hypothesis in the coffee landscape of Yayu, south-west Ethiopia, by investigating the role of local agroforestry practices (AFP) toward food and nutrition security (FNS). Through survey data collected from 300 smallholding farming households, three forms of AFP were identified : homegarden (HG), multistorey-coffee-system (MCS) and multipurpose-trees-on-farmlands (MTF). Multipurpose-trees-on-farmlands are mainly for food production, MSC for income generation and HG for both. Across all three practices, 127 useful plant species were identified, with 80 edible species of which 55 were primarily cultivated for the household food supply. The food and nutrition surveys reveal that the farming communities of Yayu are hunger free. However, about 20% of the households face moderate to severe food insecurity through limited access to food, regardless of seasons. The prevalence of wasting, underweight and stunting indicate certain forms of hidden hunger, such as iron deficiency. Coupling AFP and FNS data reveals that household access to all three AFP was the primary basis of household’s food security. A search for specific options to address the detected seasonal and nutritional gaps identified plant resources both within and around the AFP in Yayu. Out of 25 potentially edible species, 12 were confirmed to be available during the shortage season. Nutritional assessment of these species revealed species with good potential to enhance the supply of calories, protein and vitamin A. The maintenance of landscape mosaic diversity is key to food security in this coffee landscape.
