Spatial Mismatches between Cyclone Exposure and Food System Impacts in Vanuatu: Integrating Topographic, Agro-Ecological, and Infrastructure Mediators for Resilience Planning

Universal Journal of Food Security | Vol 3, Issue 1

Analytical integration of four data streams into three composite indices reveals the mechanistic complexity underlying Vanuatu's exposure-impact disconnect. Meteorological forcing (IBTrACS, VMGD), agricultural capacity (VNSO, DARD), infrastructure connectivity (Maritime Dept, OSM), and topographic positioning (SRTM DEM) each contribute distinct explanatory dimensions that, when integrated into HEI, ISI, and FSRe, collectively account for 86% of food security impact variance undetected by exposure-only frameworks.
