We examined the diffusion of agricultural innovations that improve smallholder well-being in sub-Saharan Africa. Innovations are slowly being accepted in the region, but villagers of Dogonkiria in Niger are an exception in adopting a technology known as farmer-managed natural regeneration (FMNR). We employed an exploratory qualitative methodology based on Everette Rogers’ diffusion of innovation (DOI) theory to investigate the microlevel dynamics behind the success of FMNR. Our findings demonstrate that the top-down technology transfer model required robust local-level participation, with local knowledge being a substantial element in the diffusion process. In effect, the area is experiencing improved crop yield and availability of wood for construction and energy. The results enhance understanding the relationship between external agents (state and non-state actors) and local beneficiaries in the context of new technology dissemination.
