The objective of this paper was to examine the role of biodiversity in sustaining diverse forms of multifunctional farming practices while at the same time providing ecological services to subsistence-oriented farming families in the region of study through mechanisms as (a) crop species diversification, (b) management of spatial heterogeneity, and (c) diversification of nutrition-sensitive landscapes. Our analysis shows that crop associations between cereals and legumes or between perennials and annuals, have overall positive effects on soil characteristics and often improve crop yields. Soil heterogeneity is produced by woody perennials and termites. Local management provides opportunities to collect a diversity of nutrition-rich species year-round and sustain household nutrition. specialized Agroforestry Ecological engineering Intercropping Nutritional functional diversity Termites AFRIQUE DE L'OUEST BURKINA FASO ZONE SEMIARIDE ZONE SOUDANOSAHELIENNE 098 054 056 18 76-85 2018 2211-9124 https://www.documentation.ird.fr/hor/fdi:010074105 10.1016/j.gfs.2018.08.005 2211-9124 [F B010074105] https://www.documentation.ird.fr/hor/fdi:010074105 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers18-10/010074105.pdf IRD - Base Horizon / Pleins textes 2018-11-07 2023-07-11 fdi:010074105 fre
