Human factors affecting risk and vulnerability — Eduqas A-Level Geography

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.

• →Vulnerability: The degree to which a population is susceptible to harm from a hazard, influenced by factors like poverty, age, and access to resources.
• →Capacity to cope: The ability of individuals or communities to anticipate, respond to, and recover from a hazard, often linked to economic wealth, infrastructure, and social networks.
• →Risk perception: How cultural beliefs, past experiences, and education affect people's awareness and willingness to take protective actions.
• →Governance and corruption: Weak institutions, lack of building codes, and corruption increase vulnerability by reducing preparedness and response effectiveness.
• →Demographic factors: Age, gender, and disability affect vulnerability; for example, the elderly and women in patriarchal societies often face higher risks during disasters.

• Economic factors including level of development and level of technology
• Social factors including population density, population profile (age, gender), and levels of education
• Political factors including the quality of governance
• Geographical factors including rural/urban location, time of day, and degree of isolation

• 💡Ensure you can link specific human factors to the severity of the impact of a tectonic event.
• 💡Use examples in contrasting contexts to demonstrate how vulnerability varies.
• 💡Distinguish clearly between primary and secondary hazards when discussing vulnerability.
• 💡Use specific case studies to illustrate human factors. For example, compare the 2004 Indian Ocean tsunami (high death toll due to lack of warning systems) with the 2011 Japan tsunami (better preparedness but still significant losses due to nuclear risk).
• 💡Always link human factors to the hazard risk equation. Show how a factor like 'poor governance' increases vulnerability and reduces capacity to cope, thereby increasing overall risk.
• 💡Evaluate the effectiveness of mitigation strategies. For instance, discuss why cyclone shelters in Bangladesh have reduced deaths but still face challenges due to cultural resistance or maintenance issues.

• Misconception: 'Natural hazards are the main cause of disaster deaths.' Correction: Human factors often determine death tolls; for instance, poor building standards and lack of evacuation plans cause most fatalities, not the hazard itself.
• Misconception: 'Wealthy countries are always less vulnerable.' Correction: While wealth reduces vulnerability, it can also create new risks, such as reliance on complex infrastructure that fails catastrophically (e.g., Hurricane Katrina in the USA).
• Misconception: 'Vulnerability is only about poverty.' Correction: Vulnerability is multidimensional, including social marginalisation, political instability, and lack of education, which can affect even middle-income groups.
