This guide builds on the three previous versions of the Farm Forestry Field School (FFFS) manual prepared by the Intensified Social Forestry Project in Semi Arid Areas (ISFP) of Kenya. The manual was first developed in a workshop setting with the participation of Kenya Forest Service (KFS) staff members and JICA experts at the onset of the ISFP in 2004. FAO was involved in the workshop providing technical assistance to design the FFFS implementation process, facilitate the workshops and compile workshop outputs into the manual. The ISFP conducted the manual review twice through workshops. The KFS field staff members who carried out the FFFS presented the reality of the field and issues faced by farmers. Such experience sharing enriched the entire project implementation process and subsequently this publication. FAO was tasked to finalize the reviews and was asked to carry out an independent external review in 2007.
