Disaster Risk Reduction and Management (DRRM) is an important global concern, aggravated by the concerns on climate change producing more serious natural hazards. The brunt of the legwork for DRRM is situated at the local or grassroots level - communities, local government and other locally situated development actors. In the Philippines, the Disaster Risk Reduction and Management Act (RA 10121) clearly states the active involvement of provinces, municipalities, cities and barangays for reducing and minimizing disaster risks. However, there are practical challenges for these local governments to function effectively and efficiently. To make sure of optimal resource use and decision making for this important public service task, Philippine LGUs need relevant information on hazards and societal vulnerability. Aside from the usual disaster-related information that has accrued through the years, LGUs need substantial information on the socioeconomic situations of their respective constituencies. Community-based Monitoring System (CBMS) datasets are seen as a viable source of socioeconomic data to generate relevant information to be used for disaster risk reduction and management. This study shows that CBMS information can provide pertinent information for use in the disaster risk reduction planning, disaster response, information dissemination, human resource management, networking, and legislative support. The study recommends: more effort to establish a robust and applied set of guidelines for local governments; more studies to better understand how CBMS can be utilized for DRRM; initiatives to further strengthen local DRRM functionalities; and greater horizontal linkages among local government units to allow mutual learning, systematic cooperation and other synergies for mitigating disaster risks and reducing disaster vulnerabilities in society.
