A Coastal Vulnerability Assessment and Mapping was conducted by the Mines and Geosciences Bureau (MGB) XII Geohazard and Engineering Geology Section (GhEGS) in Kalamansig and Lebak, Province of Cotabato.
The assessment included the use of the Coastal Integrity Vulnerability Assessment Tool (CIVAT), shoreline mapping and documentation of shoreline characteristics, beach profiling and sediment sampling.
CIVAT is used to determine the overall state of the coast resulting from its geologic history, the bio-physical processes that continuously shape and re-shape it and impacts of human activities. The priority coastal barangays were determined in consideration of their inherent vulnerability, wind surges affecting these areas and, the population along the coastal area, among other variables.
Coastal Vulnerability Assessment enables the government to plan for a risk reduction program for coastal barangays that experience coastal erosion. Coastal erosion is a result of several geologic, oceanographic, and atmospheric factors, including the relative sea level rise due to climate change. The rise of sea level has also been attributed to man-made activities.
A revalidation and monitoring will be conducted in the assessed coastal barangays identified to be highly vulnerable to coastal erosion. These activities are just one of the many efforts of the government relevant to climate change mitigation, adaptation, and disaster preparedness.
