Adaptive strategies in urban elevation change for flood risk management: the case of Mamminasata Metropolitan Regions, Indonesia

Abstract

This research aims to analyze elevation change as an adaptation strategy for flooding, identify the dynamics and patterns of adaptation and collaboration between actors, and evaluate the impact of elevation change on the urban environment of Mamminasata, Indonesia. This research uses qualitative methods with interpretative phenomenological analysis (IPA). Data collection involved observations, in-depth interviews, and documentation. The results show that elevation changes in buildings, land, and road infrastructure trigger an increase in elevation adaptation strategies by actors while expanding the flood-affected areas as a consequence of such measures. The nature of actors’ strategies varies; communities tend to be spontaneous, independent, and informal, while developers and the government employ business strategies and policy support tactics. Consequently, these strategies are fragmented among actors because of the lack of uniformity in elevation regulations. This reflects a pattern of longterm urban adaptation, even in the absence of formal coordination or regulation. Elevation changes negatively impact ecosystems, land stability, and social and physical connectivity. This study recommends the application of elevation changes in planning regulations for zoning and land-use management, as well as collaborative governance, to support adaptation strategies of actors and promote sustainable urban resilience.
