Community mapping for disaster risk reduction and management: Harnessing local knowledge to build resilience

This document describes training and mapping activities conducted at the community level using OpenStreetMap (OSM) tools in the Philippines to assist local government units (LGUs) in disaster risk management and decision-making. These mapping efforts produced more robust municipal base maps that included road classifications, waterways, public facilities that can serve as evacuation centres, and land use designations. These OSM base maps were then integrated with InaSAFE software to develop impact scenarios and produce flood impact maps that show the risk to infrastructure, settlements and population centres.

Working with the municipalities of Candaba, Guagua and Lubao, the mapping exercises were designed to support local government decision making, disaster contingency planning, and land use planning to reduce disaster risk.
