According to the indicators that approximate extrinsic factors, a high adoption potential for agroforestry is likely to be found in Angola, Botswana, Cameroon, Cabo Verde, Gabon, Ghana, Mauritania and Senegal. A very low potential exists in Somalia, Eritrea, South Sudan and Rwanda. Concerning recommendable advice, we suggest that smallholder farmers of countries with an identified large potential should be receiving stronger public policy support from national governments. Aside national governments, the international community can further enourage farmers to develop a positive perception of the environmental benefits, such as carbon sequestration, through agroforestry. However, until today the share of Clean Development Mechanism (CDM) projects on agroforestry (group Afforestration & Reforestation) amounts to only 0.8\% of all CDM projects issued \cite{uneprisoecentre2014}. \citep{uneprisoecentre2014}.  Future investigations are required to identify stimuli to strengthen international cooperation in the CDM on agroforestry. For the low-performing countries, future research is needed to identify the key challenges on a per-country basis that lead to a low potential and investigate particularly the relevancy of intrinsic factors on farmers' perceptions, attitudes and knowledge on agroforestry. Due to a lack of primary data, this instrinsic factors could not be evaluated in this study.
