The Philippines is considered as a climate “hotspot” and is widely regarded as one of the world’s most disaster-prone countries reflecting both its high incidence of natural hazard events and significant vulnerability. The experiences during Typhoon Haiyan in Tacloban City point to significant issues on disaster response pertaining to humanitarian logistics management (HLM). A critical element in designing a robust HLM system is evidence-based demand forecasting to facilitate the formulation of appropriate designs and operating plans. The study assessed different levels of risk for three hydro-meteorological hazards (typhoons, floods and rain-induced landslides) and related exposure of population in Tacloban City using the preliminary results of the 2011 Community Based Monitoring System (CBMS) as well as information from existing government data, available research, people’s accounts, and other studies. The Sphere Project Minimum Standards for Humanitarian Response served as basis demand forecasting in terms of food and non-food requirements of potentially affected populations.
