Human factors affecting risk and vulnerability

Human factors affecting risk and vulnerability explore how social, economic, political, and cultural conditions shape a community's exposure and sensitivity to natural hazards. This topic is central to WJEC A-Level Geography because it moves beyond physical processes to examine why some populations suffer disproportionately from disasters. Key ideas include how wealth, governance, education, and gender roles influence a society's ability to prepare for, respond to, and recover from hazards like earthquakes, floods, or tropical storms.

Understanding human factors is crucial because it explains why a hazard of the same magnitude can have vastly different impacts in different places. For example, the 2010 Haiti earthquake (magnitude 7.0) killed over 200,000 people, while a similar magnitude earthquake in Christchurch, New Zealand (2011) caused far fewer deaths. This disparity is largely due to differences in building standards, emergency services, and economic resilience. Students must grasp that vulnerability is not just about physical exposure but is socially constructed.

This topic links to broader themes in the WJEC specification, such as the 'hazard risk equation' (Risk = Hazard × Vulnerability / Capacity to Cope) and the concept of resilience. It also connects to sustainable development goals, particularly those addressing poverty, inequality, and sustainable cities. By studying human factors, students learn to evaluate mitigation strategies and understand why top-down approaches often fail without community engagement.
