Complex multispatio-periodic land use and land cover change processes, and woody resources management in a forest-Savanna Ecotone, Ghana

Vegetation change discourse in tropical Africa is characterized by assumptions of generalised deforestation and degradation. Premised on the concept of the heterogeneity of the tropical African landscape, we make a multispatio-periodic analysis of land use and land cover change (LULCC), and examine...
