ABSTRACT: The Manila Bay coastal area in The Philippines was evaluated for the possible consequences of accelerated sea level rise in the context of climate change and to assess adaptive responses to such threats. The coastal area is an important region in terms of commercial, industrial, agricultural, and aquacultural activities of The Philippines. Results show that areas along the coast if inundated by a 1 m sea level rise would include coastal barangays from 19 municipalities of Metro Manila, Bulacan, and Cavite and would cover an area of 5555 ha. Proposed response strategies consist of protecting the coast by building sea walls; institutional actions such as formulation of setback policies and construction regulations; and adaptive planning in the context of an integrated coastal zone management to address the short- and long-term problems, with the involvement of communities in the area. Information, education, and communication are essential along with the technical and scientific efforts to achieve a well-balanced adaptation plan.

KEY WORDS: Accelerated sea level rise · Vulnerability · Sustainability · Adaptation · Integrated coastal zone management plan
