Abstract
Land cover change detection supports many kinds of environmental and human development initiatives in both developed and developing countries over the past twenty-three years, Laos has experienced massive changes in land use resulting in corresponding increases in surface temperature. These changes have been little studied or evaluated empirically. To address this gap, this research study focused on tracking land cover change detection (LCCD) and Land surface temperature (LST) change in the study area of Thakhet Laos. Landsat 5, 8, and Modis datasets were used to analyze the relationship between land use and LST from 2000 to 2023. According to the LCCD results, the forest area decreased from 46,912 km² in 2000 to 33,955 km² in 2023, likely due to human activities and urban transition, while bare land increased and agricultural land decreased. In 2000 the LST values in the study area varied widely. The lowest recorded value is 24°C while the highest is 33°C. In 2023, the LST values ranged from 20°C to 41°C, this indicates an increase in temperatures compared to the previous years overall. The observed increase in urban areas, such as population movement, economic development, industrialization, and urban job creation could be a factor driving the LCCD and LST change.
