Drivers of land use change and carbon mapping in the savannah area of Ghana

Land-use and land-cover change in both forest reserves and off-reserves is a critical issue in sub Saharan Africa. Deforestation and conversion of forest land to agricultural land continue to be one of the major environmental problems in Africa, and for that matter, Ghana cannot be exceptional; and its resultant effect is the loss in the ecological integrity and the quality of forests, resulting in carbon loss and the resultant climate change effects (FAO 2016). The study area covers the Community Resource Management Areas (CREMA) of the Mole National Park in Ghana, and this study reveals that the area is well endowed with a diverse composition and structure of woodland including dense, open and riverine stretches, which – under the national definition of forest – qualifies as forest. The results reveal that there had been an annual deforestation rate of 0.11% over the period of review. It was concluded from the study that woodland had high carbon stocks with an average carbon of 80 tC/ha, the highest being 194 tC/ha and the lowest being 7 tC/ha, which was recorded in the dense woodland and grassland respectively. The fluxes within the land sector in the study area are moderate and the potential of the area to qualify for as REDD+ is very high. However, the drivers of deforestation, especially bush fires and illegal timber harvesting, are challenges that need to be addressed.
