Degradation of Forest Reserves in Asunafo Forest District, Ghana
Forest reserve degradation is a global concern because it is a storage facility of global biodiversity. In addition, forest reserves contain the wealth of several poor countries, particularly in Africa. Such is the situation in Ghana, which possesses portions of the tropical African rainforest. The timber species thereof has been harvested to create wealth since the 1800s. The wealth of the soils for cocoa production was realised in the first decade of the nineteenth century in Asunafo. Hence, the desire to reserve portions of the forest as protected areas began in 1910. Therefore, the aim of this study is an investigation of the degradation of the forest reserves of Asunafo. The methods of the study include a survey of farmers, key informant interviews, community meetings, and transect drives. The results reveal a progressive increase in the human population, expansion of settlements, and a drastic reduction in the forest reserves by –24.59%. The timber industry, cocoa farming, and population increase have caused forest reserve degradation, a loss of wildlife habitats, an out-migration of elephants, buffalos, and chimpanzees, a loss of plant biodiversity, and an invasion by weeds. The Government of Ghana should increase efforts to halt forest reserve degradation.

Gain and Loss of Forest Cover in Ghana’s Forest Reserves in Three Selected National Parks
Forests play an important role in the ecological, environmental, socio-economic and cultural lives of people. However, human-nature-forest interactions bring imbalances in the state of these resources, hence the need to monitor and manage the forest proactively. This chapter, therefore, assessed the gains and losses of three national parks in Ghana (including Mole, Digya and Kakum) for the period 1986 to 2020. Landsat TM and Landsat8 OLI images were used for the assessment. The Digya National Park has a spatial extent of 4121.89 km2. In 1986, the extent of the close forest cover was 88.0% of the park and it declined to 82.8% in 2020, a loss of 6.2%. The Kakum National Park covers an area of 463.42 km2. The close forest cover was 90.15% and 89.52% of the extent of the park in 1986 and 2020, respectively. The Mole National Park covers about 4602.19 km2. In 1986, 86.73% of the park was open forest, which was reduced to 80.83%, a loss of 5.90%. The study revealed 67% of open forest degradation, 33% loss of close forest and a reported ritual bushfire, wood harvesting and lumbering as the unsustainable practices in the forests. Reclamation of degraded areas is recommended to the Forestry Commission.
