Abstract

This study identified the factors that influence household recovery following an extreme flood event, measured in terms of the length of time to repair, rebuild or replace damaged private property. Data was obtained through a survey of 400 households in Marikina City in Metro Manila, Philippines. Results from the empirical analysis indicated that household income, access to credit (borrowing), the use of a flood alarm system, access to safe shelter, membership in a community organisation, adoption of disaster-specific anticipatory measures and adoption of general preventive measures significantly reduced the time it took for affected households to recover from property damage. Evacuation, relief aid, type of housing, education, household size and frequency of flooding in the area did not have significant effects.

Highlights

Summary

Introduction

Many parts of Metro Manila, the national capital region of the Philippines, are vulnerable to flooding. Its location between Manila Bay in the west and Laguna de Bay to the southeast makes it a drainage basin that is subject to frequent overflowing of storm waters. One of 17 cities and municipalities that make up Metro Manila, the City of Marikina experienced some of the worst flooding in recent history. Local leaders must prioritise the most effective forms of aid that would have the biggest impact on vulnerable members of the community. Located along the eastern border of Metro Manila, the City of Marikina is situated in a valley between the Sierra Madre Mountains to the east and the hills of Quezon City to the west. Most of the flooding in the city’s low-lying areas is a result of the runoff from the slopes of the Sierra Madre mountain range that run along the east of Marikina Valley. Given no exact definition for an ‘extreme flood event’, such is interpreted by this study as flooding that results from extreme rainfall, which is defined by the PAGASA as rainfall exceeding 300 mm in 24 h
