This paper challenges conventional mainland-centric urban theories by examining the unique urbanization processes of small urban islands in Getafe, Bohol. Through an ethnographic and spatial analysis of island communities experiencing land subsidence and tidal flooding, the study explores the concept of "rising and sinking" as a dual metaphor for developmental growth and environmental vulnerability. The research highlights how island residents negotiate limited space, resource scarcity, and climate-induced changes through localized adaptation strategies and informal urbanism. By documenting these lived experiences, the author argues for a rethinking of urbanization that accounts for the "archipelagic" nature of the Philippines, moving toward planning frameworks that are sensitive to the specific ecological and socio-spatial realities of small-island societies.
