| All of the subject municipalities are affected by coastal degradation or erosion. The municipalities of Sibulan, Bacong, Dauin and Zamboanguita situated on the eastern coast of the province have undergone the highest rate of coastal erosion during the northeast monsoon or “amihan” while the Southwest Monsoon or ”Habagat” affected the municipality of Basay located on the western part. Ironically, while the other barangays of Basay are experiencing degredation, Barangay Actin experienced coastal deposition. Based on the testimony of the residents living along the coastal area of Barangay Actin, the shoreline advanced by about 50 meters in 30 years. The sediments, which are dominantly sand deposits, have naturally compacted and consolidated into a hard, dense rock-like materials. According to barangay officials of Actin, most of these sediments are believed to be from the former mining site of CDCP Mining Corporation.
