The Rammang-Rammang karst area is one of the two karst areas in the world that are drained by rivers. This karst area has been a Geopark National Park since 2017 and is being proposed as a world cultural heritage or World Site Heritage (WSH). This protected area is directly adjacent to community settlements so that it demands economic development, trade, transportation, services, and has implications for increasing the need for housing and settlements for tourists. The emergence of various activities if not controlled will reduce the environmental quality of the karst area. For this reason, this study aims to identify environmental, social, economic, and institutional conditions around the Rammang-Rammang Karst area, Maros Regency; Develop a settlement arrangement strategy with an eco-settlement concept approach.
