1. Context
Metropolitan Manila, one of the world’s largest urban agglomerations, faces a high level of disaster displacement risk associated with earthquakes, frequent flooding, and fire hazards. In Manila’s Navotas City, for example, some 250,000 residents are concentrated in just one quarter of the city’s almost 11 square kilometre strip of land on the shore of Manila Bay. Despite being Southeast Asia’s biggest fishing port, Navotas is prone to frequent flooding caused by typhoons, heavy monsoon rains and high tides, especially near waterways and fishponds.1 At particular risk are migrant labourers from other regions in the Philippines, who live in poor-quality shanties in informal settlements along the coastline and riverine waterways.2
