Developing Adaptive Coastal Resilience Strategies to Alleviate the Negative Impacts of Coastal Road Construction in San Luis, Batangas

The ongoing coastal road construction in San Luis, Batangas, while promising improved connectivity and economic development, presents substantial socio-economic, environmental, and cultural challenges. This study aims to critically examine the adverse impacts of the project and to propose adaptive coastal resilience strategies appropriate to the municipality’s specific conditions. The objectives are threefold: (1) to evaluate existing coastal infrastructure policies and identify gaps affecting community resilience; (2) to formulate adaptive strategies that address the environmental, social, and economic dimensions of the development; and (3) to offer evidence-based recommendations for local government and stakeholders to support sustainable coastal planning. Employing a mixed-methods research design, the study integrates quantitative surveys conducted in six coastal barangays, qualitative data from focus group discussions (FGDs), and key personnel interviews (KPIs), as well as geospatial analysis and policy document reviews. Descriptive statistics and weighted mean computations were utilized to assess community perceptions and quantify the multi-dimensional impacts of the coastal road. Key findings indicate that the infrastructure project has exacerbated shoreline erosion, disrupted local fisheries, displaced residents, and negatively affected small-scale enterprises. Additionally, there is a perceived lack of inclusive stakeholder consultation and insufficient integration of climate-adaptive planning mechanisms. The analysis further reveals critical policy gaps in achieving environmental sustainability and equitable development. The study concludes that without adaptive interventions, the ongoing infrastructure development may heighten ecological degradation and socio-economic vulnerabilities. Nevertheless, through the adoption of nature-based solutions, enhanced policy frameworks, and participatory planning processes, San Luis can effectively transition towards a resilient and sustainable coastal future. The proposed strategies underscore the importance of community engagement, ecological preservation, and collaborative governance in fostering adaptive resilience in coastal municipalities.
