Abstract

Land use – the way human beings employ the land and its resources is at the centre of scientific and policy interests in rapidly evolving landscapes of sub-Saharan Africa. An example par excellence of such landscapes is the Western Highland Region of Cameroon. This paper analyses the implications of land use changes in seven communities of the Western Highland Region of Cameroon. In doing so, it specifically: (i) examines the pattern of land use/land cover change between 1984 and 2021, and (ii) analyses their environmental implications. A mixed-methods approach involving the use of qualitative and quantitative data collection and analysis methods was employed. This specifically involved the survey of 300 households using semi-structured questionnaires, the conduct of nine (9) group discussions and twenty-two (22) key informant interviews. Secondary data were obtained through Municipal Council Reports. The data were analysed descriptively (using tables and charts) and spatially using maps. The study used archived satellite images to map land use dynamics over the study area from 1970’s to present. In this light, NASA’s Landsat satellite images from USGS earth explorer was acquired for the periods of 1979, 1984, 2000, 2013 and 2021 for diachronic analysis of land cover/use in the study area. The results revealed that land use/land cover changes were rapid, involving a significant reduction in grassland (72%), forests (48%) and bare areas (19%) between 1984 and 2021. This was followed by a correspondent increase (211%) in the built-up area, and in agricultural space (22%). Additionally, land use/land cover changes have led to a change in local climatic conditions, a decline in crop and livestock output, and rising food costs. The study recommends that international NGOs operating in this area should engage with communities on aspects of sustainable land management. Relevant government ministerial departments and municipal agents should emphasise the need to respect land use plans, to limit the uncoordinated colonisation of slopes for farming and settlement. Besides establishing the pattern of land use transformation in this landscape, this paper provides new insights on the environmental effects of land use/land cover dynamics in Cameroon’s Western Highlands. The results demonstrate novelty through its further identification of food security issues linked to land use/land cover dynamics.
