Understand the concept
A hazard is a potentially damaging event or process. Disaster risk depends on hazard, exposure, vulnerability and capacity; a hazard does not become a disaster in every setting. Risk reduction begins before an emergency through safe land use, building standards and ecosystem protection. Preparedness develops plans, skills and resources; response addresses urgent needs; recovery rebuilds services and livelihoods. Institutional arrangements link national, state, district and local responsibilities under applicable law.

Disaster management: an overlapping cycle
The cycle is an organising model, not a rigid timetable. Recovery should feed safer future development.

Mitigation: Reduce potential harm through safer land use, building standards and ecosystem protection.; Preparedness: Build plans, skills, warning systems, supplies and inclusive readiness.; Response: Protect life, meet urgent needs and coordinate assistance using assessed requirements.; Recovery: Restore livelihoods and services while reducing the vulnerabilities that produced the loss.

Carry this into your answer: Risk arises from hazard, exposure, vulnerability and capacity; the natural event alone does not explain damage.
Study the topic in depth
01From a natural event to a social disaster
A hazard is a potentially harmful event or process; a disaster involves serious disruption when that event interacts with exposed and vulnerable systems. A strong earthquake in an uninhabited area and an earthquake of similar intensity beneath unsafe buildings do not produce identical consequences. The hazard alone does not explain the loss.
Exposure identifies people, assets and activities in harm's way. Vulnerability describes susceptibility to damage, influenced by housing, health, income, social exclusion and environmental conditions. Capacity includes knowledge, institutions, resources and networks that help anticipate and cope. These concepts should be connected, not treated as interchangeable labels. A population may be exposed but relatively well protected; another may have limited options even after receiving a warning.
02Risk is produced through development choices
Development can reduce risk through safe housing, drainage and reliable health systems. It can also create risk when construction occupies floodplains, infrastructure ignores hazards or livelihoods depend on fragile systems. The important shift is from asking only how to respond after loss to asking how today's investment changes tomorrow's exposure.
A project appraisal should examine location, design, maintenance and dependence on other services. A hospital needs more than a strong building: electricity, water, communication and access routes must remain functional. This is systemic risk, where failure in one network disrupts others. Risk-informed planning therefore requires coordination across departments rather than a separate emergency plan added at the end.
03The management cycle is not a rigid timetable
Mitigation reduces potential harm; preparedness builds readiness; response addresses immediate needs; recovery restores and improves systems and livelihoods. In practice these activities overlap. A relief shelter may need repairs while recovery planning begins, and reconstruction decisions should already incorporate mitigation.
Residual risk remains even after protective measures. A city with improved drainage still needs warning and response arrangements for events beyond design assumptions. Insurance and relief finance can help manage losses, but they cannot replace prevention. Nor should a response success be used to excuse repeated creation of avoidable exposure through poor planning.
04Institutions must connect authority with local capacity
National policy and specialised support are important, but much of risk reduction happens through local land use, building practice, public services and community knowledge. Effective institutions clarify who monitors a hazard, who issues a warning, who authorises action and who maintains assets. Ambiguous responsibility causes delay even when resources exist.
Budgets and staff must match assigned duties. A district plan that lists many departments without contact arrangements, exercises or resource mapping is not operational readiness. Accountability includes examining whether risk information changed decisions before an emergency. Avoid reducing disaster governance to the deployment of response forces after an event.
05Sendai as a planning framework
The Sendai Framework connects understanding risk, stronger governance, resilience investment and preparedness with safer recovery. Its significance is the move toward preventing new risk and reducing existing risk. It also recognises that government responsibility works alongside participation by communities, businesses and other actors.
For Mains, convert these priorities into an administrative chain: map risk, assign responsibility, fund protective measures, rehearse action and review outcomes. A diagram is useful only when the explanation shows how these steps interact. A strong conclusion links disaster policy with ordinary development decisions, because land use, infrastructure and inequality shape losses long before an emergency is declared.
Examples, applications & distinctions
Hypothetical hospital-planning illustration
A district proposes a hospital on inexpensive low-lying land. The building can be elevated, but the only access road floods and the power substation is nearby. Examining the whole service network may favour a safer site despite higher initial cost. This illustrates how risk-informed development protects continuity, rather than merely strengthening one structure.

Disaster losses arise when hazards interact with exposure, vulnerability and limited capacity. Development decisions influence all these conditions, making risk reduction a continuing responsibility rather than a task beginning after an emergency.
Land-use planning determines whether settlements and infrastructure occupy hazardous locations. Building quality, drainage and ecosystem protection influence the damage a hazardous event can cause. Health, income and social inclusion affect whether people can understand warnings, evacuate and recover. Consequently, similar events can produce very different losses.
Risk reduction must therefore enter project appraisal and public investment. A hospital requires safe construction as well as dependable water, electricity, communication and access. Evaluating these interdependencies prevents a structurally sound facility from becoming unusable when supporting networks fail.
Institutions also need clear responsibilities and adequate capacity. Local authorities require technical support, resources and enforceable standards. Plans should be tested through exercises and revised when weaknesses emerge. Community knowledge improves mapping and communication, but does not replace public responsibility.
Emergency response remains indispensable because residual risk cannot be eliminated. However, relief and insurance cannot compensate for repeatedly creating avoidable exposure. Recovery should rebuild safer services and livelihoods instead of reproducing the vulnerabilities that caused loss.
The Sendai approach provides a useful direction by linking risk knowledge, governance, investment and preparedness. Its practical meaning is that everyday decisions about housing, infrastructure and services must become risk-informed. A resilient development process reduces both future emergencies and the unequal burdens they impose on vulnerable people.
