= Introduction =

'''Disaster Risk Reduction''' or '''DRR''' is the organized effort to prevent new disaster risk, reduce existing risk, and manage the risk that remains. A hazard such as an earthquake, flood, cyclone, wildfire, heatwave, epidemic, or industrial accident does not automatically become a disaster. A disaster occurs when a hazardous event interacts with exposed people and assets, vulnerability, and limited capacity strongly enough to cause serious disruption. Understanding this difference helps you move from simply reacting to disasters toward making schools and communities safer before an emergency happens.<ref>[https://www.undrr.org/terminology/disaster UNDRR: Disaster] and [https://www.undrr.org/terminology/disaster-risk UNDRR: Disaster risk], accessed 2026.</ref>

This UNDRR introduction connects disaster risk reduction with the idea of [[English:Resilience|resilience]].

This course is designed for learners in '''Grades 9–10'''.

By the end of this aiMOOC, you should be able to explain the main components of disaster risk, compare prevention, mitigation, preparedness, response, and recovery, read a simple risk scenario, evaluate school and community safety measures, and design practical actions that reduce risk.

{{BR}}
== Hazard, Exposure, Vulnerability, and Capacity ==

'''Hazard''' means a process, phenomenon, or human activity that may cause harm. Hazards can be natural, human-induced, or a combination of natural and human influences. Examples include earthquakes, river floods, droughts, wildfires, extreme heat, chemical spills, and infrastructure failures.<ref>[https://www.undrr.org/terminology/hazard UNDRR: Hazard], accessed 2026.</ref>

'''Exposure''' describes people, buildings, infrastructure, livelihoods, and other assets located in places where hazards may occur. A school beside a flood-prone river is more exposed to flooding than an otherwise similar school on higher ground.<ref>[https://www.undrr.org/terminology/exposure UNDRR: Exposure], accessed 2026.</ref>

'''Vulnerability''' describes physical, social, economic, and environmental conditions that increase susceptibility to harm. Weak construction, lack of access to warnings, poverty, unsafe land use, and damaged ecosystems can increase vulnerability. Vulnerability is not a permanent label attached to a person; it depends on conditions that can often be changed.<ref>[https://www.undrr.org/terminology/vulnerability UNDRR: Vulnerability], accessed 2026.</ref>

'''Capacity''' means the strengths, resources, knowledge, institutions, relationships, and skills that help people manage and reduce risk. Trained teachers, accessible evacuation routes, emergency communication systems, strong buildings, trusted local organizations, and first-aid knowledge are examples of capacity.<ref>[https://www.undrr.org/terminology/capacity UNDRR: Capacity], accessed 2026.</ref>

A useful way to think about disaster risk is that it grows when hazards, exposure, and vulnerability are high, and it can be reduced when capacity is strengthened. This relationship is a conceptual model rather than a single universal mathematical formula. Real risk assessment also considers the type, location, intensity, frequency, and probability of hazards as well as social, economic, health, and environmental conditions.<ref>[https://www.undrr.org/terminology/disaster-risk-assessment UNDRR: Disaster risk assessment], accessed 2026.</ref>

[[File:Cyclone Shelter (15265520285).jpg|500px|frameless|center]]
A cyclone shelter shows how infrastructure can increase community capacity in a hazard-prone area.

{{BR}}
== Hazard Is Not the Same as Disaster ==

Imagine two earthquakes of similar strength. In one place, buildings follow seismic codes, older structures have been strengthened, people know safe actions, and emergency services are prepared. In another place, many buildings are weak, evacuation routes are unclear, and emergency services have few resources. The physical hazard may be similar, but the likely impacts can be very different because exposure, vulnerability, and capacity differ.

This is why the phrase '''natural disaster''' can be misleading. Many hazards have natural causes, but disaster impacts are strongly shaped by human decisions about where and how people build, how resources are distributed, whether warnings reach everyone, and whether institutions plan for risk.

[[File:Steel braced frame added to an unreinforced masonry bearing-wall building as a seismic retrofit.jpg|500px|frameless|center]]
Adding a steel braced frame to an older masonry building is an example of seismic retrofitting that can reduce structural vulnerability.

{{BR}}
== Risk Drivers and Unequal Impacts ==

Disaster risk is affected by underlying drivers such as poverty and inequality, climate change, rapid or unplanned urbanization, unsafe land management, environmental degradation, weak regulation, and limited access to technology or public services.<ref>[https://www.undrr.org/terminology/underlying-disaster-risk-drivers UNDRR: Underlying disaster risk drivers], accessed 2026.</ref>

The same warning or evacuation plan may not work equally well for everyone. A person with limited mobility may need an accessible route. A newcomer may need information in a language they understand. A family without a car may need public transport or a nearby safe shelter. Good DRR therefore includes different voices when planning and checks whether safety measures are accessible, understandable, and realistic.

{{BR}}
= From Risk Assessment to Action =

{{BR}}
== Risk Assessment and Mapping ==

A risk assessment asks what can happen, who and what could be affected, how serious the impacts could be, what capacities already exist, and what actions could reduce risk. At school level, you can begin with a simple walk-through and map.

A school risk map might mark fire exits, assembly areas, laboratories, electrical equipment, steep slopes, flood-prone zones, heavy objects that could fall, first-aid supplies, accessible routes, and places where students receive warnings. The purpose is not to predict the future perfectly. It is to make risk visible enough to support better decisions.

When comparing risks, consider both '''likelihood''' and '''consequence'''. A frequent small flood may deserve action because repeated disruption adds up. A rare but extremely severe event may also deserve strong preparation because the consequences could be catastrophic.

{{BR}}
== Prevention and Mitigation ==

'''Prevention''' aims to avoid existing and new disaster risk where possible. Examples include keeping new buildings out of a known high-risk floodplain or enforcing a safety rule that prevents dangerous chemical storage.

'''Mitigation''' reduces the harmful impacts of a hazard when the hazard itself cannot be prevented. Examples include strengthening buildings, constructing appropriate flood protection, maintaining vegetation to reduce erosion, installing fire-resistant materials, creating defensible space around structures, and protecting critical infrastructure.

[[File:Flood Barrier.jpg|500px|frameless|center]]
Flood barriers are one example of a structural measure designed to reduce flood impacts.

[[File:Firebreak.JPG|500px|frameless|center]]
A firebreak or fuel break can help slow the spread of wildfire by reducing available fuel across a strip of land. Its effectiveness depends on design, maintenance, weather, and fire conditions.

Non-structural measures matter too. Building codes, land-use planning, insurance, public education, drills, warning protocols, and agreements between organizations can reduce risk without being physical barriers.

{{BR}}
== Preparedness and Early Warning ==

'''Preparedness''' means developing the knowledge and capacities needed to anticipate, respond to, and recover from likely disasters. Good preparedness includes plans, drills, supplies, communication procedures, trained people, and clear responsibilities.

An effective '''early warning system''' is more than a sensor or siren. It depends on risk knowledge, monitoring and forecasting, communication of understandable warnings, and the ability of people and institutions to act. A warning that is accurate but arrives too late, uses confusing language, or gives no practical action may fail to protect people.

[[File:Indonesia early warning system officer.jpg|500px|frameless|center]]
Monitoring seismic data is one part of a warning system; communication and the ability to act are also essential.

[[File:Tsunami Evacuationroute sign.JPG|500px|frameless|center]]
Tsunami evacuation-route signs help turn a warning into action by showing people where to move.

{{BR}}
== Response, Recovery, and Build Back Better ==

'''Response''' includes actions taken directly before, during, and immediately after a disaster to save lives, reduce health impacts, ensure public safety, and meet basic needs. Examples include evacuation, search and rescue, emergency medical care, shelter, and emergency communication.

'''Recovery''' includes restoring and improving livelihoods, health, services, infrastructure, and community systems after a disaster. Recovery can create an opportunity to reduce future risk. Rebuilding a damaged school to a safer standard, relocating a critical service away from a high-risk site, or redesigning drainage so future floods cause less harm are examples of '''Build Back Better''' thinking.

Recovery should not simply recreate the conditions that produced the earlier disaster risk.

{{BR}}
= School and Community Safety =

{{BR}}
== Safe Schools ==

Schools need both safe buildings and prepared people. A school safety plan should identify local hazards, safe areas, evacuation and shelter procedures, communication methods, responsibilities, support for students with different needs, arrangements for family reunification, and ways to continue education after disruption.

[[File:Students practices earthquake drill. (10727185804).jpg|500px|frameless|center]]
Students practising earthquake safety show how drills can turn written plans into practiced skills.

A drill is useful only when it is followed by reflection. Ask: Did everyone receive the signal? Were routes clear? Was anyone excluded? Did people know what to do? Were assembly procedures efficient? What should change before the next drill?

{{#ev:youtube|https://www.youtube.com/watch?v=dQKgBQ7Mbnc|500|center}}
This UNDRR video emphasizes disaster-resistant school infrastructure, disaster education, and the role of children and young people in safer communities.

{{BR}}
== Community Participation and Communication ==

People who live with risk often know details that are missing from official maps: which road floods first, which households may need help evacuating, where water collects after intense rain, or which communication channels people actually trust. Community participation combines this local knowledge with scientific information, engineering, public policy, and emergency planning.

Clear risk communication answers practical questions: What is happening? Where? Who may be affected? When? What action should people take now? Where can they get verified updates? Communication should avoid unnecessary panic, but it should also avoid vague reassurance when action is needed.

Before sharing hazard information online, check the source, date, location, and whether an official authority or trusted scientific organization confirms it. During emergencies, misinformation can waste time and direct people toward unsafe choices.

{{BR}}
= The Sendai Framework =

The [[English:Sendai Framework for Disaster Risk Reduction|Sendai Framework for Disaster Risk Reduction 2015–2030]] is the main global framework for reducing disaster risk. It was adopted in 2015 and sets seven global targets and four priorities for action. Its goal is a substantial reduction in disaster risk and losses in lives, livelihoods, health, and economic, physical, social, cultural, and environmental assets.<ref>[https://www.undrr.org/publication/sendai-framework-disaster-risk-reduction-2015-2030 UNDRR: Sendai Framework for Disaster Risk Reduction 2015–2030].</ref>

{{#ev:youtube|https://www.youtube.com/watch?v=M9m6mb-blYM|500|center}}

{{BR}}
== Four Priorities for Action ==

The four Sendai priorities can be translated into questions you can use when evaluating a school or community:

# [[English:Disaster risk assessment|Understand disaster risk]]: What hazards, exposure, vulnerabilities, capacities, and possible impacts do we need to understand?
# [[English:Disaster risk governance|Strengthen risk governance]]: Who is responsible, who participates, what rules apply, and how are decisions coordinated?
# [[English:Resilience|Invest in resilience]]: Which structural and non-structural investments would reduce risk most effectively and fairly?
# [[English:Disaster preparedness|Strengthen preparedness and Build Back Better]]: Are people ready to act, and will recovery reduce future risk rather than restore old vulnerabilities?

The priorities are connected. Better risk information improves governance; good governance helps direct investment; investment can strengthen preparedness; and lessons from response and recovery can improve future risk reduction.

{{BR}}
= DRR, Climate Change, and Sustainable Development =

Disaster risk reduction and [[English:Climate change adaptation|climate change adaptation]] overlap because climate change can alter the frequency, intensity, duration, or location of some weather- and climate-related hazards. DRR also connects with [[English:Sustainable development|sustainable development]] because unsafe development can create new exposure and vulnerability, while risk-informed development can protect lives, livelihoods, education, health, ecosystems, and infrastructure.

Not every hazard is caused by climate change. Earthquakes, for example, are driven by geophysical processes. Good risk analysis identifies the actual causes and conditions for each hazard instead of treating all disasters as the same problem.

Nature-based approaches can sometimes reduce risk while supporting ecosystems. Healthy wetlands can store water, vegetation can stabilize some slopes, and coastal ecosystems can reduce certain wave and erosion impacts. These measures still require local scientific assessment; no single solution works everywhere.

{{BR}}
= Scenario: A School Near a River =

Suppose your school is 300 metres from a river. Heavy rainfall upstream can raise water levels quickly. The ground floor contains electrical equipment and the main server room. Some students travel by a low bridge that may become unsafe during floods. The school has a warning group chat, but mobile service sometimes fails.

A DRR analysis would not stop at saying '''flood hazard'''. You would map exposed people and assets, identify vulnerable routes and equipment, check who may need support, examine how quickly water can rise, identify safe higher areas, test backup communication, and decide which measures should happen before the next rainy season. Possible actions could include moving critical equipment to a higher floor, setting a clear closure threshold, arranging alternative routes, improving drainage where appropriate, practising evacuation, and coordinating with local authorities.

The best plan would combine technical information with the daily experience of students, staff, families, and nearby residents.
