11. Wetland wetlands are found around the Tonle Sap Lake and along the Mekong River and its tributaries The total wetlands area 0.5 million ha in the dry season to 5 million ha in the wet season The Tonle Sap Lake area 250,000 ha to 1,000,000 ha and up to 1,350,000 ha The surface of the lake from 2,700 km² to 16, 000 km²

13. Soil erosion soil erosion also being threaten in some regions throughout the country, in particular to terrain and steep slope areas where the logging activities been taken heavily

14. Wind erosion There is no data recorded in regard with deposition of soil particles in the valleys and/or plain in Cambodia

15. Water erosion Cambodia the areas that prone to mass movement located along the steep slop of Mekong, Tonle Sap and Prasac Rivers, these landslides are belong to the natural phenomenon weather and strong water flow.

16. Sedimentation Reduction Erosion is part of natural and results in sedimentation, which can have positive effects, such as fertilizing the soils, and negative effects such as making a lake shallower

17. Root cause of land degradation the major root causes of land degradation are soil erosion, deforestation, seasonal drought caused by inappropriate land use, poor agricultural activities and gemstone mining activity.
