Classifying disasters helps nurses and emergency responders to:

• Predict what might happen
• Prepare the right supplies and skills
• Respond quickly and correctly
• Prevent unnecessary deaths and suffering

🔑 Key Point: Different types of disasters need different responses. A nurse responding to a flood needs different skills than a nurse responding to a chemical spill.

Type	Definition	Simple Explanation
NATURAL DISASTERS	Events caused by natural forces of the Earth	Nature causes it; humans do not make it happen
HUMAN-MADE DISASTERS	Events caused by human actions, mistakes, or conflicts	People cause it, either by accident or on purpose

Type	Medical Term	Simple Meaning	Characteristics
SUDDEN-ONSET	MONOCAUSAL	Happens suddenly, with little or no warning	One main cause; happens fast; less time to prepare
SLOW-ONSET	MULTICAUSAL	Develops gradually over time	Many causes; happens slowly; more time to prepare but harder to stop

Category	Cause	Examples
Geophysical	Earth's natural processes	Earthquakes, volcanic eruptions, tsunamis
Meteorological	Atmospheric conditions	Hurricanes, tornadoes, blizzards, hailstorms
Hydrological	Water-related events	Floods, landslides
Climatological	Long-term climate patterns	Droughts, wildfires, heat waves
Biological	Living organisms	Epidemics, pandemics, pest infestations
Technological	Human-made system failures	Industrial accidents, nuclear incidents, cyberattacks

These happen in a moment. You have little time to run or prepare.

Disaster	What Happens	Warning Time
Storm	Violent weather with strong winds and rain	Hours to minutes
Heat Wave	Sudden extreme high temperatures	Days
Freeze	Sudden extreme cold	Days
Earthquake	Ground shaking violently	Seconds or none
Volcanic Eruption	Lava, ash, and gas exploding from mountain	Hours to days
Tsunami	Giant ocean wave hitting coast	Minutes to hours
Lightning Strike	Electric discharge from clouds	Seconds

These build up slowly. They have many causes happening over time.

Disaster	What Happens	Warning Time
Landslide	Soil and rocks sliding down a slope	Days to weeks (cracks appear first)
Drought	Long period without rain	Months
Floods	Water overflowing onto dry land	Hours to days (can be sudden too)

A natural disaster is a major adverse event resulting from natural processes of the Earth. These events have immediate impacts on human health and can lead to secondary effects that cause further harm.

• Not caused by humans: They come from nature (though human actions can make them worse)
• Can be predicted sometimes: Weather forecasts can warn of storms; earthquakes are harder to predict
• Cause secondary health problems: After the first disaster, diseases often follow
• Raise risk of preventable diseases: Because of crowding, dirty water, and poor sanitation

After a natural disaster, these problems often follow:

Primary Disaster	Secondary Health Effects
Flood	Cholera, typhoid, malaria, malnutrition
Earthquake	Crush injuries, wound infections, tetanus, PTSD
Drought	Malnutrition, famine, migration, conflict
Storm	Drowning, injuries, water contamination
Landslide	Suffocation, trauma, displacement

A drought is an extended period of insufficient rainfall that disrupts the hydrologic cycle (the natural movement of water), resulting in water shortages, crop damage, livestock death, and food insecurity.

Drought does not happen in one day. It develops when:

• Rain fails for one season
• Then another season
• Water sources dry up slowly
• Crops fail gradually
• Animals lose weight and die
• Finally, humans face starvation

Cause	Explanation
Climate change	Changing weather patterns reduce rainfall
Water shortage	Too many people using limited water
Poor farming practices	Not rotating crops, overusing land
Deforestation	Trees attract rain; without them, rainfall decreases
Overgrazing	Too many animals eat all the grass, soil becomes bare

• The Cattle Corridor: Central Uganda stretching from Karamoja to Ankole
• Karamoja Region: Most severely affected; frequent droughts lead to starvation
• Parts of Teso and Lango: Often affected by prolonged dry spells
• Northern Uganda: Especially Acholi sub-region

Effect	How It Hurts People
Starvation	No food because crops died
Malnutrition	Especially children and pregnant women
Water scarcity	People drink dirty water; diseases increase
Livestock death	Loss of income and food source
Migration	People move to other areas, causing conflict
School dropout	Children leave school to search for food/water
Conflict	Fighting over remaining water and grazing land

1. Management of Water Resources: Protect water sources (springs, wells, rivers), repair broken boreholes quickly, regulate water use.
2. Rainwater Harvesting: Build tanks to collect rain during wet seasons, use simple methods like gutters and drums.
3. Construction of Reservoirs: Build dams and ponds to store water for dry seasons, provide community water points for livestock.
4. Small-Scale Irrigation: Use simple irrigation for gardens, grow crops even when rain is little.
5. Community Awareness: Teach people about water importance, show how to conserve water at home.
6. Integrated Approach: Government agencies and NGOs must work together, share information and resources.
7. Weather Prediction and Early Warning: Use meteorological stations to predict dry seasons, warn communities early to prepare.
8. Proper Agricultural Techniques: Plant drought-resistant crops, use mulching to keep soil moist, terrace farming to prevent water runoff.
9. Drought-Resistant Crops: Sorghum, millet, cassava, sweet potatoes. These survive with little water.
10. Efficient Irrigation: Drip irrigation instead of flooding fields uses less water, gives better results.
11. Land Use Management: Plan where to farm, graze, and build, prevent overuse of fragile land.
12. Research: Develop better drought-resistant seeds, improve livestock breeds that survive dry conditions.
13. Mapping and Zoning: Identify drought-prone areas, plan differently for those areas (e.g., pastoralism instead of farming).
14. Environmental Regulations: Enforce laws against deforestation, protect wetlands that store water.
15. Immediate Relief: Provide food and water to affected people, supply fodder (food) for domestic animals.
16. Employment Programs: Give people work (e.g., road building) so they can buy food ("Food for work" programs).

• Screen for malnutrition: Use MUAC tapes on children; weigh babies
• Teach ORS preparation: Dehydration is common
• Promote breastfeeding: Breast milk does not need water
• Support vaccination: Malnourished children are vulnerable to measles
• Monitor disease outbreaks: Cholera and typhoid increase when water is scarce
• Educate on hygiene: When water is limited, teach handwashing with ash
• Refer severely malnourished: To therapeutic feeding centers

Famine occurs when a large percentage of a population in a region is severely undernourished, leading to increasing deaths from starvation.

Drought	Famine
Lack of rain	Lack of food
Causes famine	Caused by drought, war, or crop failure
Environmental problem	Humanitarian crisis

• Natural crop failures: Drought, floods, pests destroy food

1. Improve Food Production: Train farmers in modern methods, provide quality seeds and tools.
2. Establish Grain Stores: Store food in famine-prone areas, community granaries for emergencies.
3. Food-for-Asset Programs: People work on community projects (roads, dams) and receive food or cash to build community while fighting hunger.
4. Increase Production and Productivity: Use fertilizers appropriately, plant more per hectare.
5. Streamline Land Tenure: Clarify land ownership (mailo, freehold, customary) so people can invest in long-term farming.
6. Awareness About High-Yielding Crops: Promote sorghum, millet, and hybrid livestock as they produce more food per plant.
7. Modern Farming Methods: Hydroponics (growing without soil), greenhouse farming, use of irrigation.
8. Food Reserves: National and community food stocks to buffer against bad seasons.
9. Food Security and Nutrition Policies: Recognize that adequate food is a human right, government must ensure no citizen starves.

• Active case finding: Go house-to-house to find malnourished children
• Run supplementary feeding programs: Give Plumpy'Nut or fortified foods
• Treat micronutrient deficiencies: Vitamin A, iron, zinc supplements
• Prevent disease: Vaccinate all children; give deworming tablets
• Counsel mothers: On infant feeding, hygiene, and recognizing danger signs
• Document and report: Report malnutrition rates to District Health Office

An epidemic is an occurrence of a disease that surpasses the usual frequency for a specific place and time.

Simple Explanation: Normally, a village might have 2 cases of malaria per week. If suddenly there are 50 cases per week, that is an epidemic.

Displaced populations are at high risk because of:

• Migration: People move to new areas with different diseases
• Crowding: Many people in small spaces
• Unsanitary conditions: No toilets, dirty water
• Poor nutrition: Weak immune systems
• Disrupted health services: Vaccination programs stop

Disease	Why It Spreads After Disaster	Prevention
Diarrheal diseases (cholera, dysentery)	Contaminated water	Clean water, ORS, handwashing
Respiratory illnesses (pneumonia, TB)	Crowding in shelters	Ventilation, spacing, masks
Malnutrition	Food shortage	Supplementary feeding
Measles	Unvaccinated children crowded together	Vaccination
Meningitis	Close contact in camps	Vaccination, early treatment
Malaria	Stagnant water from floods	Mosquito nets, draining water

• Psychological support: Epidemics cause fear and stigma

Pest infestation is when insects or animals invade in large numbers and destroy crops, threatening food security.

• They eat crops before harvest
• They destroy stored food
• They cause economic loss
• They lead to famine

Pest	What It Destroys	Impact
Desert Locusts	Cereals, grasses, vegetables	Can eat entire fields in hours
Army Worms	Maize, sorghum, rice	Destroy staple crops
Fall Army Worm	Maize	Major threat to Uganda's food security
Rats and Vermin	Stored grain, crops	Contaminate food with urine and feces
Aphids	Beans, vegetables	Suck sap from plants, reducing yield
Stem Borers	Maize, sorghum	Bore into stems, killing plants

1. Create Awareness and Early Warning: Train farmers to recognize pest signs early, use community scouts to monitor fields.
2. Research Pest-Resistant Crops: Develop and distribute resistant varieties, use genetically modified crops where accepted.
3. Surveillance and Monitoring: Regular field inspections to track pest movement and population.
4. Spraying Crops: Use approved pesticides correctly, train farmers on safe chemical use.
5. Vermin Control: Use traps, safe poisons, and biological control (cats, owls), proper storage to keep rats out.

• Nutrition assessment: When crops fail, monitor for malnutrition
• Pesticide poisoning awareness: Teach safe use; recognize poisoning symptoms
• Food safety education: How to store food safely
• Report food shortages: Alert authorities when communities lack food

Floods are characterized by the overflow of water onto normally dry land. The land becomes submerged.

• Floods account for approximately 30% of the world's disasters each year
• They affect more people than any other natural disaster

Cause	Explanation
Heavy rainfall	Rain falls faster than ground can absorb
River overflow	Rivers burst banks after upstream rain
Deforestation	Trees hold soil and absorb water; without them, water runs off quickly
Uncontrolled urbanization	Concrete covers ground; water cannot sink in
Poor drainage	Blocked or insufficient drains in cities
Dam breakage	Walls of dams break, releasing massive water
Wetland destruction	Wetlands act as sponges; without them, flooding worsens

Effect	Description
Drowning	People and animals caught in fast-moving water
Accidents	Falls, electrocution from downed power lines
Displacement	People forced to leave homes
Loss of homes	Houses destroyed or submerged
Loss of food sources	Crops washed away; food stores ruined

Effect	Description
Disease outbreaks	Cholera, typhoid, leptospirosis, malaria
Further displacement	People cannot return home for months
Malnutrition	Food supplies destroyed
Mental health problems	Anxiety, depression, PTSD
Economic loss	Businesses destroyed, jobs lost

3. Protect and Restore Wetlands: Stop draining wetlands for construction, plant papyrus and water-loving trees.
4. Proper Physical Planning: Plan cities with drainage in mind, set back buildings from floodplains.
5. Gazette Flood Basins: Legally designate areas that should flood, keep these areas free of settlement.
6. Land Use Planning: Zone areas as "no-build" if prone to flooding, enforce zoning laws.
7. Avoid Construction in Floodplains: Do not allow homes in areas that naturally flood, relocate people already living there.
8. Afforestation in Catchment Areas: Plant trees in areas where rivers begin, trees slow water and allow it to sink into ground.
9. Build Physical Structures: Reservoirs to hold excess water, channels to direct water away from homes, levees and dykes along rivers.
10. Prevent Human Encroachment: Stop farming and building in catchment areas, protect river sources.

Tsunamis, also known as seismic sea waves, are massive waves generated by underwater disturbances.

Cause	How It Creates a Tsunami
Underwater earthquake	Plate movement displaces huge volume of water
Underwater landslide	Soil slides into ocean, pushing water forward
Volcanic eruption	Underwater explosion displaces water
Meteorite impact	Rare; object hitting ocean creates massive wave

• In deep ocean: Waves may be only 1 meter high but travel at 500-800 km/hour
• As waves approach shallow coastal areas, they slow down but grow to incredible heights (10-30 meters or more)
• They crash into shore with devastating force
• Water rushes inland, destroying everything

• Uganda is landlocked — direct tsunami risk is very low
• However, Ugandans living near or visiting coastal areas (Mombasa, Dar es Salaam) should know tsunami signs
• Lake tsunamis (seiches) can occur on Lake Victoria from earthquakes

• Strong earthquake near the coast
• Sudden ocean receding — Water pulls back, exposing sea floor
• Loud roar from the ocean
• Official warnings via radio/TV

• Uganda nurses may respond as part of international teams
• Mass casualty triage
• Wound care (cuts from debris)
• Infection control in crowded shelters
• Psychological support for traumatized survivors

Earthquakes are sudden movements within the Earth's crust accompanied by earth vibrations (shaking).

• Can occur any time of the year
• Considered one of the most destructive natural forces
• Often happen without warning

Injury Type	Cause
Cuts and lacerations	Broken glass, flying debris
Broken bones (fractures)	Falls, being hit by falling objects
Crush injuries	Being trapped under collapsed buildings
Dehydration	Trapped in rubble for days without water
Suffocation	Buried under debris, dust inhalation
Burns	Fires following earthquake
Stress reactions	Psychological trauma

5. Check Electrical Installations: Regular inspection by electricians, replace old wiring.
6. Equip Fire Brigades: Train and equip firefighting institutions, establish regional fire facilities.
7. Partnerships: Work with companies that have firefighting equipment, share resources during big fires.

• Smoke Alarms: Install smoke alarms — they decrease chances of dying in a fire by half. Place on every level of the house, outside bedrooms on the ceiling or high on the wall, at the top of open stairways, bottom of enclosed stairs, near (but not in) the kitchen. Test and clean once a month, replace batteries at least once a year, replace smoke alarms every 10 years.
• Have Emergency Numbers Ready: Keep fire brigade telephone number in safe, accessible place, teach all family members.

• If Your Clothes Catch Fire: STOP, DROP, and ROLL until fire is extinguished. DO NOT RUN.
• To Escape a Fire: Check closed doors for heat before opening using the back of your hand. NEVER use palm or fingers. Crawl low under smoke, close doors behind you as you escape, stay out once safely out.

• Cool and cover burns to reduce further injury or infection.
• If you detect heat or smoke when entering damaged building, evacuate immediately.
• If tenant, contact landlord.
• Seek medical attention even for small burns.

• Burn care: Assess depth and extent of burns (rule of nines)
• Airway management: Smoke inhalation can swell airways
• Fluid resuscitation: Burn victims need lots of IV fluids
• Tetanus prophylaxis: Burns are tetanus-prone wounds
• Infection control: Burn wounds easily infected

• Respiratory care: Smoke inhalation, asthma attacks
• Burn care: Same as fire victims
• Evacuation support: Help move vulnerable people
• Long-term monitoring: Erosion and landslide risk after fire

Cyclones are characterized by massive air masses rotating around a central area of low atmospheric pressure. They have inward-spiraling winds.

• Form when heat and moisture create a low-pressure center over tropical oceans with warm water
• Cyclones intensify and accelerate toward the center
• The warmer the ocean, the stronger the cyclone

Name	Region
Hurricanes	Atlantic Ocean, Caribbean
Typhoons	Western Pacific
Cyclones	Indian Ocean, Bay of Bengal
Willy-willies	Australia

Type of Damage	How It Happens
Strong winds	Blow away roofs, uproot trees, throw debris
Heavy rainfall	Causes flooding
Storm surge	Wall of ocean water pushed inland; most deadly
Secondary flooding	Rivers overflow from rain
Landslides	Saturated hillsides collapse

• Uganda is landlocked and does not face oceanic cyclones directly
• However, tropical storms from the Indian Ocean can bring heavy rains
• Strong windstorms do occur, especially in flat areas

• Prepare for mass casualties before storm hits
• Triage after storm passes
• Manage flood-related illnesses (cholera, malaria)
• Care for injuries from flying debris
• Support displaced populations in shelters

Hailstorms produce solid precipitation in the form of ice lumps (hailstones).

• Size of ice lumps depends on thunderstorm intensity
• Produced by cumulonimbus clouds (tall, dark storm clouds)
• Can turn the landscape white like snow

Target	Damage
Crops	Beat down and destroy standing crops
Livestock	Injure or kill animals caught outside
Vehicles	Dent cars, break windshields
Roofs	Damage iron sheets, cause leaks
People	Bruises, head injuries, even death from large hail

• Treat traumatic injuries (head wounds, bruises)
• Support farmers who have lost crops (mental health)
• Document injuries for disaster reports

Landslides and mudslides are the rapid movement of mud, rocks, and soil down a slope.

Cause	Explanation
Heavy rainfall	Water saturates soil, making it heavy and slippery
Earthquakes	Ground shaking loosens soil
Groundwater flow	Underground water weakens soil structure
Deforestation	Tree roots hold soil; without trees, soil slides
Poor farming practices	Ploughing up and down slopes instead of across
Mining	Underground tunnels weaken ground support

Landslides are challenging to predict exactly, but risk factors can be assessed:

2. Resettlement: Move people already living in danger zones, provide land and support for relocation.
3. Afforestation: Plant trees on steep slopes to let tree roots stabilize soil.
4. Enforce Laws and Policies: Environmental protection laws, land use regulations.
5. Appropriate Farming Technologies: Terrace farming (steps on hillsides), contour ploughing (across the slope), agroforestry (mixing trees with crops).
6. Slope Support: Build retaining walls, install rock bolts and mesh.
7. Reservoirs and Drainage: Construct reservoirs to control water flow, create drainage channels to direct water away from weak slopes.
8. Monitor Mining Activities: Ensure mines do not destabilize ground, reclaim mined land properly.
9. Tree Planting on Unstable Slopes: Native species with deep roots (e.g., bamboo is excellent for holding soil).

• Cracks appearing in ground or walls
• Doors and windows sticking (ground shifting)
• Sudden appearance of springs or seeps
• Tilting trees, poles, or fences
• Rumbling sounds from uphill
• Rapid increase in stream flow

• Evaluation: Did the community recover? Were secondary disasters prevented?

Q1: Differentiate between natural and human-made disasters, giving two examples of each.
Answer: Natural disasters are caused by natural forces of the Earth (e.g., earthquakes, floods). Human-made disasters result from human actions or failures (e.g., industrial explosions, war).

Q2: What is the difference between sudden-onset and slow-onset disasters?
Answer: Sudden-onset (monocausal) disasters occur quickly with little warning (e.g., earthquakes, explosions). Slow-onset (multicausal) disasters develop gradually over time (e.g., drought, famine).

Q3: List four types of environmental pollution.
Answer: Air pollution, water pollution, soil pollution, solid waste pollution, noise pollution. (Any four)

Q4: Why are displaced populations at high risk of disease epidemics?
Answer: Because of migration, crowding, unsanitary conditions, poor nutrition, and disrupted health services.

Q5: Name three drought-prone areas in Uganda and three prevention measures.
Answer: Areas: Karamoja, cattle corridor, parts of Teso, Acholi, Lango. Prevention: Rainwater harvesting, drought-resistant crops, small-scale irrigation, afforestation, water resource management.

Q6: What are UXOs, and why are they a problem in Uganda?
Answer: UXOs are Unexploded Ordnances — bombs or shells that did not explode but remain dangerous. They are a problem in areas affected by past conflicts (e.g., Northern Uganda from LRA conflict).

Q7: List the three categories of wildland fires.
Answer: Surface fire, ground fire, and crown fire.
