Managing Hazard Risk - TCE Geography (Tasmania)
“Hazard risk is managed across the disaster cycle through prevention, mitigation, preparedness, response and recovery at multiple scales.”
Hazard risk management reduces harm through a cycle of prevention, mitigation, preparedness, response and recovery. Strategies operate from local to global scales and are judged on how well they cut exposure and vulnerability, their cost, feasibility and equity.
What this dot point is asking
Once a hazard and its risk are understood, the geographic task is to manage that risk so harm is reduced. Management is usually organised around the disaster management cycle, which moves through prevention and mitigation before an event, preparedness ahead of an anticipated event, response during and immediately after, and recovery in the longer term. The most cost-effective management focuses on the before phases, because reducing exposure and vulnerability in advance saves far more than reacting after a disaster.
Prevention is concerned with the long-term and aims to avoid the risk altogether, for example by prohibiting building on floodplains or in high bushfire-risk zones through planning controls. Mitigation reduces or eliminates the impact if the hazard does occur, for example fuel-reduction burning to lower bushfire intensity, levees and improved drainage for floods, building codes and retrofitting for earthquakes, and seawalls or managed retreat for coastal hazards. Preparedness involves actions taken before advance notice to build the capacity of communities to respond and recover, including early-warning systems, evacuation plans, emergency services training, public education and stockpiling resources.
Structural and non-structural measures taken to reduce or eliminate the impacts of a hazard, such as engineering works, land-use controls and ecosystem management, undertaken before an event occurs.
Response is the immediate action during and just after an event: issuing warnings, evacuating, search and rescue, emergency relief and restoring essential services. Recovery is the longer process of rebuilding infrastructure, restoring livelihoods and supporting community wellbeing, ideally building back better so future risk is lower. Effective management links these phases so that lessons from recovery feed back into prevention and mitigation.
Tasmania provides detailed examples. Bushfire management combines prevention (planning controls limiting development in extreme-risk areas), mitigation (fuel-reduction burning by the Parks and Wildlife Service and brigades, and rapid remote-area firefighting to protect Gondwanan vegetation), preparedness (the statewide Total Fire Ban system, the Australian Fire Danger Rating System, community bushfire-ready plans and the message to leave early), response (the Tasmania Fire Service and emergency broadcasts) and recovery (rebuilding and support after major fires). Flood management after the 2016 floods involved warnings from the Bureau of Meteorology, levee and drainage works in some towns, and planning reviews of floodplain development. Coastal hazard management increasingly weighs hard structures against planned retreat as sea levels rise.
Take fuel-reduction burning for bushfire. Strengths: lowers fuel loads and fire intensity, protects assets and lives, relatively low cost. Limitations: narrow safe-burning windows as the climate warms, smoke and health impacts, risk of escape, and ecological harm to fire-sensitive species. A strong evaluation states the goal (mitigation), weighs effectiveness against cost, feasibility and equity, and concludes that it is valuable but insufficient alone, needing preparedness and planning controls alongside it.
Management operates across scales, which determines the levers available. Local councils control land-use planning and emergency arrangements; state governments run fire and emergency services and set building standards; national bodies coordinate disaster funding and meteorological warnings; and global cooperation, such as the Sendai Framework for Disaster Risk Reduction, sets shared goals and shares knowledge. Each scale faces different constraints of funding, authority and political will.
Investing in prevention, mitigation and preparedness is widely shown to be far cheaper than paying for response and recovery after a disaster. Yet political and funding pressures often favour visible post-event spending, which is why under-investment in the before phases is a recurring management weakness.
Hazard-management questions usually ask you to evaluate, not list. Choose clear criteria (reduction in exposure and vulnerability, cost, feasibility, equity and time scale), apply evidence to each strategy, weigh strengths against limitations and reach a reasoned judgement about the best mix for a given place and hazard.
For TCE assessment, organise your answer around the management cycle, match strategies to the specific hazard and place, and evaluate them against explicit criteria. Use a detailed Tasmanian case such as bushfire alongside a global example, and recognise that climate change is expanding risk, so management must adapt rather than rely on historical patterns.
Exam-style questions
Questions in the style of TASC exam questions on this dot point, each with a worked answer. They are written by ExamExplained unless tagged "Past paper"; the year shows the paper a question is modelled on.
Practice6 marksUsing the disaster management cycle and a Tasmanian hazard, give one strategy for each of the prevention, preparedness and response phases.Show worked answer →
A 6 mark source response must map real strategies onto the labelled phases of the cycle.
Read the diagram. Identify the phases (prevention and mitigation, preparedness, response, recovery) and their order around the cycle.
Match strategies to a hazard. For Tasmanian bushfire: prevention is planning controls limiting building in extreme-risk zones; preparedness is the Australian Fire Danger Rating System and the leave-early message; response is Tasmania Fire Service action and emergency broadcasts.
Markers reward a strategy correctly placed in each named phase and matched to a specific hazard and place, not a generic list.
Practice12 marksEvaluate the effectiveness of strategies used to manage hazard risk, and assess the view that prevention is more effective than response. Use a detailed Tasmanian example.Show worked answer →
A 12 mark evaluation must weigh strategies across the cycle against criteria and judge the prevention-versus-response claim.
Strategies. Organise around the cycle: prevention and mitigation (planning controls, fuel-reduction burning), preparedness (warnings, community plans), response (firefighting, evacuation) and recovery (rebuilding better).
Evaluate the claim. Argue with evidence that investing in the before phases is far cheaper and saves more lives than post-event response, citing Tasmanian bushfire management, while conceding that response and recovery remain essential and that climate change is widening risk beyond historical patterns.
Judgement. Conclude that prevention and preparedness are generally more cost-effective, but a complete strategy needs all phases. Markers reward explicit criteria, a detailed local case and a reasoned position.
