Abstract

This study examines the vulnerability, adaptation, and resilience of urban poor households living in the riverine communities of the three flood prone areas in Metro Manila, namely, (1) Pasig-Marikina River basin, (2) West Mangahan, and (3) the KAMANAVA area (Kalookan, Malabon, Navotas, Valenzuela). Based on a survey of 300 urban poor households in 14 communities located in these flood basins, the study found that the environmental-ecological vulnerability of the low-lying flood prone areas interacts strongly with the social vulnerability of urban poor households, highlighting the effects of climate related changes (sea level rise, increased typhoons, intensity of monsoon rains, floods and tidal/storm surges) on this vulnerable population.

Most of the households have low-incomes, live in slum/squatter settlements and do not have adequate access to potable water, electricity, health, sewage and sanitation facilities. About two-thirds of them suffered losses (e.g., income, work, health/sickness, household appliances/things, housing damage) from typhoons, floods, and tidal/storm surges but only a small portion of them obtained help from formal institutions (e.g., local government units or LGUs, charitable agencies) and informal support networks (relatives/neighbors/friends). Of these, a third of these households appeared more vulnerable and consistently incurred higher losses (e.g., income and workdays) and intense inconveniences (e.g., water source buried by floods, toilets blocked and overflowed with wastes/large worms to their floors) compared to their neighbors.

Both urban poor households and their local governments have formulated adaptation strategies in response to the increasing effects of climate change. Few of the local governments built river barriers, improved their drainage systems, installed water diversion techniques (e.g., “bombastic”) and disaster warning systems and increased the capacity of their officials to assist during evacuations. Meanwhile, some urban poor households have adapted to a “water-based lifestyle” (e.g., raising the floors/increasing the number of floors of their homes, building makeshift bridges among households in swampy areas, building Styrofoam boats for transport, etc.). But on the whole, both the urban poor residents and the formal institutions (LGUs, national agencies) need resources and capability building to increase their capacity to adapt to the effects of climate change.
