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

Figure 7

Food security resilience declines systematically from north to south across Vanuatu, but vulnerability drivers differ fundamentally between provinces. Sanma's buffered stronghold status (FSRe = 61) reflects balanced capacity across all dimensions, while Torba's moderate score (FSRe = 57) conceals critical infrastructure deficits masked by strong agro-ecological buffering — the defining hidden hotspot profile. Tafea and Shefa occupy the critical/fragile category (FSRe 46–47) for structurally distinct reasons, underscoring that spatially differentiated — not uniform — adaptation strategies are required across the archipelago. Provinces scoring within 3 FSRe points of a category boundary (Torba: 57; Malampa: 58) are considered transitional; sensitivity analysis confirms ranking stability (Spearman ρ > 0.88) under ±20% weight variation.
