ICRAF and partners since 1987 in collaboration with farmers and national institutions have developed promising agroforestry technologies that provide significant benefits to smallholder farmers. In order for agroforestry to have impact on rural poverty, food security and environmental conditions, these technologies need to be scaled up to many farmers, and spread widely across the landscape and to have a critical mass of capacity at grass root levels. In this paper we present results of work by ICRAF and partners that is helping farmers and their families take steps out of chronic poverty and gaining sustainable development towards Africa green revolution. Today over 417,503 farmers in Malawi, Tanzania, Zambia, Zimbabwe and Mozambique (189,854 farmers in western Tanzania) are enjoying benefits through agroforestry focusing on working trees grown on farms and rural landscapes, that include “Fertilizer” trees for land regeneration, soil health and food security, fruit trees for nutrition, fodder trees that improve small holder livestock production, timber and fuelwood trees for shelter and energy and trees that produce various products and medicinal trees that combat diseases.
