What is hazard mapping and how is it used in environmental health and action?

• A. Hazard mapping is only a historical record of past events with no current use.
• B. Hazard mapping identifies hazards and vulnerabilities geographically to inform siting and preparedness, focusing on preventive actions.
• C. Hazard mapping is optional in humanitarian action.
• D. Hazard mapping forecasts only weather patterns.

Answer: (B)

Hazard mapping is the practice of identifying various hazards and the communities and assets at risk, then representing this information on a map. In environmental health and humanitarian action, this means combining data on hazards such as floods, storms, droughts, heat, pollution, disease vectors, and industrial accidents with where people live and receive services, along with critical infrastructure. The resulting maps show where exposure and vulnerability overlap, guiding preventive actions like siting clinics, water points, and shelters; directing investments in risk reduction and resilience; planning evacuations and allocating supplies; and tailoring risk communication to those most at risk. It’s a proactive tool used to inform siting and preparedness, not just a historical record or a weather forecast.
