Abstract

Climate change has become a global challenge with significant impacts on coastal areas, including Banggae Timur Subdistrict, Majene Regency. Phenomena such as coastal abrasion, tidal flooding, infrastructure damage, and declining economic productivity threaten the sustainability of local livelihoods. This study aims to formulate community-based climate change adaptation and mitigation strategies tailored to local conditions, while supporting the achievement of the Sustainable Development Goals (SDGs), particularly SDG 13 (Climate Action), SDG 11 (Sustainable Cities and Communities), SDG 14 (Life Below Water), and SDG 17 (Partnerships for the Goals).
A mixed-method approach was employed, combining vulnerability analysis using the IPCC AR4 framework with strategy formulation through the Analytic Hierarchy Process (AHP) and the Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE). Data were collected through questionnaires, in-depth interviews, field observations, and document review.
The results indicate that the communitys vulnerability level in Banggae Timur is medium to high, influenced by coastal hazard exposure, economic dependence on marine resources, and limited institutional adaptive capacity. AHP-PROMETHEE analysis prioritized adaptation strategies such as strengthening local institutional capacity and community participation, developing climate-resilient coastal infrastructure, and diversifying livelihoods based on local resources. Mitigation strategies include coastal ecosystem rehabilitation, improving energy efficiency, and integrating climate policies into local development planning.
This study provides practical contributions for local governments, academics, and communities in formulating inclusive adaptation and mitigation policies. The implementation of these strategies can accelerate SDG achievement through the synergy of disaster risk reduction, ecosystem protection, and the strengthening of socio-economic resilience in coastal communities.
