Exposure Analysis of Tacloban City’s Humanitarian Supply Chain to Climate-Related Hazards: Towards a Risk-informed Site Selection Process
Abstract
Public service continuity calls for facilities that can withstand the impacts of hazard events without significant damage or loss of functionality. Using geospatial analysis, the study evaluated the coastal City of Tacloban's critical point facilities (CPFs) and road network— those identified to provide essential support services in times of crisis - for exposure to sea-level rise (SLR) and the three other hazards of (1) flooding, (2) storm surge, and (3) rain-induced landslide. The study found that many of the City's CPFs and most road networks
linking these facilities are at high risk of some, if not all, of these hazards. This finding substantiates the City's Super Typhoon (ST) Haiyan experiences, confirming weaknesses in the design of disaster supply chains that should be resolved to prevent further impacts on affected sectors. This study illustrates how the exposure analysis of humanitarian supply chain assets to various climate-related hazards can provide decision-makers with a firm understanding of the number and location of assets that may be compromised per hazard. Towards evidence- based decision-making, the paper elaborates on using Geographic Information Systems (GIS)-based conjunctive multi-criteria decision analysis (MCDA) for risk-informed site selection.
