Abstract
Understanding land use and land cover changes and their underlying dynamics is critical to land reclamation and biodiversity management in mining enclaves and deceleration of desertification in the vast Zamfara Sahel of Northwestern Nigeria. This paper presents a quantitative analysis of land cover changes in the gold mining enclaves of Anka, Bukkuyum and Maru Local Government Areas in Zamfara State, Nigeria. Data were aggregated from field trips, remote sensing and geographical information system technologies and archives. Data and satellite images from three time periods of 1987, 2002 and 2020 were used for the analysis. The images were captured on yearly degradation rates of LULC classes within 100m, 200m and 300m of protected areas. Five LULC classes were identified and twenty-five transition classes were mapped out using GIS technology. Analysis shows bare ground/ built-up/rock outcrop LULC class expanded as mining activities had deleterious impacts on the land cover of the enclaves.
