Abstract
The Davao Region, particularly Davao City, faces escalating threats from sea level rise (SLR) driven by global climate change, posing significant risks to its densely populated coastal communities and critical infrastructure. This study employs Geographic Information System (GIS) analysis and high-resolution Digital Elevation Models (DEMs) to identify and map areas vulnerable to inundation under projected SLR scenarios for 2050 and 2100. Results indicate that by 2050, a 0.4-meter SLR could affect approximately 695 hectares across 30 barangays, while a 2.0-meter rise by 2100 may inundate nearly 2,903 hectares in 50 barangays, with low-lying districts such as Bunawan (Poblacion), Alejandra Navarro, Bucana, and Lizada identified as persistent risk hotspots. The findings highlight a rapid expansion in both the spatial extent and severity of SLR impacts, highlighting the need for targeted adaptation and resilience strategies, particularly for the most vulnerable barangays. The study emphasizes the urgency of integrating scientific SLR projections into urban planning, disaster risk reduction, and climate adaptation policies to safeguard Davao Citys socioeconomic stability and the well-being of its coastal communities.
