Central and West Africa are increasing areas of interest for the PHE approach, although some PHE projects have been implemented within this region for several years. This section encompasses a wide spectrum of geographic areas, ranging from the Sahel, a semi-arid to arid area, to the Congo rainforest. The materials in this sub-tab come from projects in, or that pertain to, Central and/or Western Africa as a region, or specific countries within the region.
