Land reclamation in Metro Manila
The reclamation of land from the surrounding waters of Metro Manila is used to expand the region's limited area of usable and natural land. There are about 25 projects that aim to reclaim more than 10,000 hectares (100 km2) of land in Manila Bay from the city of Navotas to the province of Cavite.
