This paper will examine the factors influencing the sustainability of integrated coastal management (ICM) projects in the Philippines, specifically in two locations, Bais Bay area of Negros Oriental and Mabini-Tingloy area of Batangas, where a number of ICM projects have been implemented since the mid-1980s. Indicators for ICM project impacts are developed and analyzed to determine their relationships with ICM project sustainability. Years of residency in the community, participation in ICM projects with resource management and enterprise/alternative livelihood activities, and the total number of projects participated in were the strongest predictors of perception of ICM project sustainability at the two sites in the Philippines. Participation of community members in the ICM project design and implementation and real or perceived economic benefits from the project influence participants to sustain project activities after project completion.
