Carbon dynamics in cocoa agroforestry systems in Central Cameroon: afforestation of savannah as a sequestration opportunity

Afforestation of savannah is suggested as an approach to help addressing climate change mitigation through increased carbon (C) storage. Previous studies in Central Cameroon evidenced farmers’ ability to realize afforestation by establishing cocoa-based agroforestry systems (cAFS) on humid savannah. In this forest-savannah transition zone, we studied an 80 years chronosequence of cAFS to assess C dynamics. We selected cAFS established after forest or savannah, and we used local forest and savannah patches as controls.
