摘要：
The Atewa Range Forest Reserve (ARFR) in Ghanais threatened by anthropogenic activities. This study used geospatial techniques to assess the effects of human activities on land use and land cover (LULC) dynamics in ARFR using Landsat satellite images of 1986, 1991, 2006 and 2016. Estimated Normalized Differential Vegetation Index showed a continuous decline in LULC, signifying increasing stress on vegetation in ARFR. Between 1986 and 2016, the rainforest reduced from 345.83km(2) to 183.48km(2); logged land declined from 324.52km(2) to 186.21km(2); farmland increased from 328.43km(2) to 384.68km(2); and settlement expanded from 110.48km(2) to 354.91km(2), respectively.
