Leveling mountains and destroying taluses for construction destabilize the terrain, create steeper slopes and sacrifice local vegetation. This fuels the risk of erosion and landslides," he said, adding erosion occurred mainly on mountain slopes, in residential areas or along roads and other man-made structures.
