Abstract

The Maiganga coal mine in Gombe State, Nigeria, has undergone significant land use changes and land surface temperature (LST) variations due to coal mining activities, raising substantial concerns about its environmental sustainability. This study comprehensively assessed the environmental sustainability of the Maiganga coal mine, with the following objectives; analyze spatiotemporal patterns of Land Use and Land Cover (LULC) changes from 2005 to 2023; quantifying variations in LST, and examine the relationship between LST changes and shifts in land use. LULC data for 2005, 2010, 2015, 2020, and 2023 were used, similarly data set was used for the LST sourced from the United States Geological Survey. Leveraging ArcGIS the data were analyzed using supervised classification and thermal analysis, which enabled a comprehensive assessment of LULC changes and LST variations. The result shows a remarkable decline in farmland, ultimately diminishing by 100% by 2023. This was coupled with a significant expansion of bare land, encompassing 64.32% of the total land cover. Concurrently, vegetation exhibited a continual decline across the study period. Furthermore, a pronounced increase in LST values was observed from 2005 to 2010. The correlation analysis established a substantial positive relationship between LST changes and the proliferation of both bare land (r = 0.82, p < 0.05) and coal mining areas (r = 0.76, p < 0.05), underscoring the direct association between the expansion of these land cover types and rising LST. This study highlighted the profound influence of coal mining on the landscape and its implications for local temperature dynamics within the Maiganga region. It emphasized the urgency of adopting proactive environmental management strategies to mitigate adverse effects while promoting sustainable land use practices. Therefore, the study recommended that policymakers and mining companies should prioritize environmentally friendly mining practices and implement robust land reclamation strategies, striving to harmonize economic growth with environmental conservation in the Maiganga area.
