Land use changes in Cameron Highlands from 2009 to 2019 were studied using satellite images. Primary forests decreased by 35.98 km2, while agricultural and urban areas increased by 51.61 km2 and 11.00 km2, respectively. The most affected elevation range was between 1000 and 1500 m. Agriculture and urban development expanded onto steep slopes, causing soil instability. Land surface temperatures rose by 7.5°C on average, with some areas experiencing a 3-4°C increase. These findings can help government and land planners make better decisions to protect the environment in Cameron Highlands.
