Climate change has significantly impacted coastal communities in Ambon City, leading to coastal erosion, tidal flooding, and declining fish catches. This study analyzed adaptation strategies employed by coastal communities using a socio-ecological approach. The research employed a qualitative case study method, including field observations, in-depth interviews, and geospatial analysis. Data were collected from several coastal areas in Ambon City and were analyzed using the Social-Ecological System (SES) model to understand community adaptation patterns. The findings revealed that communities implement three main adaptation strategies: (1)physical adaptation, such as constructing seawalls and rehabilitating coastal ecosystems; (2) economic adaptation through livelihood diversification, including ecotourism and small-scale enterprises; and (3) social adaptation, involving institutional strengthening and environmental education. The integration of technology, such as early warning systems and ecology-based aquaculture, plays a crucial role in enhancing community resilience. Collaboration among communities, the government, and other stakeholders is essential for developing more sustainable adaptation policies. This study recommends a more holistic, community-based approach to strengthen the resilience of coastal communities in Ambon City against the ongoing impacts of climate change.
