Abstract
This study was carried out to assess the Land Surface Temperature (LST) of Minna City and Environs, Niger State, Nigeria. Land surface temperature has caused significant ef ects to water bodies, loss of vegetal cover and animal
species, loss of city comfort as well as critical health condition of city residents. The study utilized satellite remotesensing and Geographic Information System (GIS) to derive LST imageries. Landsat 5, 7 and 8 were usedtogenerate LST of Minna Town and environs from 2002 to 2023. The results showed that in 2002, land surfacetemperature varied between 21.50
oC and 46.95
oC with a range of 25.45.5
oC indicating the highest range inthestudy. LST increasingly spread to all parts of the city indicating areas of high urban pavement material
concentration and growth. In 2014, LST varied between 11.39oC and 41.31oC ranging 29.92oC indicatingatremendous rise in LST. In 2023, LST varied between 12.31
oC and 43.12
oC with a range of 30.81
0Cshowingtheyear with the highest range of LST growth. The study highlights the urgent need for strategic urban planninginterventions to mitigate the adverse impacts of rising LST and urban heat islands in Minna. Incorporating moregreen infrastructure, regulating pavement expansion, and managing urban growth can substantially reduce surfacetemperatures and improve human comfort.
