Mountain Disasters and the Risks for Autistic Children in Nepal: A Post-Disaster Parental Guide

Introduction

Natural disasters can affect every family, but for children with autism, a sudden disaster can create additional challenges.

A major mountain-related disaster can happen very quickly. Floodwater, landslides, debris, damaged roads, power outages, evacuation, unfamiliar shelters, loud sounds, and separation from familiar surroundings can completely change a child's daily environment.

The catastrophic event in Rasuwa on 26 August 2026, followed by impacts along the Bhote Koshi and Trishuli river corridors including Nuwakot, has demonstrated how rapidly a mountain-origin disaster can affect communities far downstream. The Government of Nepal and WHO reported extensive impacts on communities, infrastructure, health services, transportation, and emergency response. The precise sequence that triggered the Rasuwa flooding continues to be investigated.

This situation is particularly important for families raising autistic children.

An autistic child may have difficulty communicating during an emergency, coping with sudden changes, tolerating unfamiliar sensory experiences, or understanding why normal routines have suddenly disappeared.

This article is therefore not only about the disaster itself.

Its main purpose is to help parents understand:

Understanding Mountain-Related Disasters in Nepal

Nepal's geography creates several types of natural hazards.

The country contains high Himalayan mountains, glaciers, steep slopes, narrow valleys, major rivers, and settlements located along river corridors and mountain roads.

Because of this geography, communities can be exposed to hazards such as:

• Flash floods
• Glacial Lake Outburst Floods (GLOFs)
• Landslides
• Debris flows
• Rockfalls
• Avalanches
• Earthquakes
• River flooding

Some of these events can occur with very little warning.

What Is a Glacial Lake Outburst Flood?

A Glacial Lake Outburst Flood (GLOF) occurs when water stored in or around a glacial lake is suddenly released, producing a powerful downstream flood.

Nepal has a significant history of GLOF events and continues to have areas that require monitoring.

ICIMOD's inventory of glacial lakes in the Koshi, Gandaki, and Karnali basins identified 21 potentially dangerous glacial lakes in Nepal as part of a wider regional assessment. These lakes can pose risks to downstream communities and infrastructure if they breach.

GLOFs are only one example.

Mountain communities can also experience sudden flooding caused by combinations of landslides, avalanches, ice or rock movement, temporary river blockages, and the rapid release of water.

The Rasuwa Disaster: Why It Matters for Families

On 26 August 2026, severe flooding affected parts of central Nepal.

According to WHO Nepal, communities along the Bhote Koshi and Trishuli river corridors were affected, including Rasuwa, Nuwakot, Dhading and Chitwan, with other districts also affected. The initial flooding in Rasuwa followed a sudden surge of water into the Bhote Koshi River, possibly associated with an upstream ice avalanche and temporary damming of the Lhende River; investigations are ongoing.

The Government of Nepal reported severe loss of life and property and initiated search, rescue, relief, and rehabilitation efforts.

The event demonstrates an important point for families:

Water and debris can travel downstream through connected river systems, affecting communities far from the original mountain source.

For parents of autistic children, this means disaster preparedness should not depend only on whether a family lives directly beside a glacier or at the disaster's point of origin.

Families living along vulnerable river corridors and in other hazard-prone areas should understand their local risks and know where to seek safety.

Why Autistic Children May Face Additional Risks

Autism does not automatically make a child physically more vulnerable to a flood, landslide, or earthquake.

However, certain characteristics associated with autism can create additional challenges during emergencies.

These may include:

1. Communication Difficulties

Some autistic children may have limited spoken language or may be non-verbal.

During an emergency, they may have difficulty telling others:

• “I am hurt.”
• “I am scared.”
• “I am hungry.”
• “I am thirsty.”
• “I need the toilet.”
• “I want my parent.”
• “Something hurts.”

This can make emergency assessment more difficult.

2. Difficulty Understanding Sudden Danger

A child may not understand why everyone suddenly needs to leave the house.

They may not understand:

Simple, repeated explanations may therefore be necessary.

3. Sensory Overload

Disasters can create an unusually intense sensory environment.

A child may experience:

• Sirens
• Helicopters
• Loudspeakers
• Crowds
• Generators
• Flashing lights
• Mud
• Rain
• Strong smells
• Unfamiliar clothing
• Physical contact from unfamiliar people

A child who is already sensitive to sound, touch, light, or certain textures may become extremely distressed.

4. Loss of Routine

Many autistic children find predictable routines helpful.

A disaster can suddenly change:

• Wake-up time
• Meals
• School
• Therapy
• Sleeping location
• Bathing
• Toileting
• Transportation
• Family routines

This sudden loss of predictability can increase anxiety and behavioral distress.

5. Unfamiliar Environment

An emergency shelter, relative's house, school building, or temporary camp may contain unfamiliar:

• People
• Sounds
• Smells
• Beds
• Food
• Toilets
• Lighting
• Rules

For some children, this can be overwhelming.

6. Risk of Wandering or Becoming Separated

Some autistic children may wander or move away from caregivers, particularly when frightened or overwhelmed.

During an evacuation or crowded emergency situation, parents should therefore pay particular attention to supervision and identification.

Children who are attracted to water may also require additional precautions around flooded areas and rivers. Autism-focused disaster preparedness guidance specifically recommends considering wandering and water-safety risks during emergencies.

The Risks Do Not End When the Water Goes Down

One of the most important messages for parents is:

The family may face:

• Displacement
• Loss of home
• Interrupted schooling
• Interrupted therapy
• Loss of familiar belongings
• Medication shortages
• Poor sleep
• Changes in eating
• Fear
• Anxiety
• Communication difficulties
• Behavioral changes
• Separation from family members
• Uncertainty about the future

For an autistic child, these changes can continue to affect daily functioning long after the physical disaster has ended.

BEFORE A DISASTER: Parent Preparation Guide

Preparedness is one of the most useful things a family can do.

Parents do not need an expensive or complicated plan.

A simple child-specific emergency plan can make a significant difference.

1. Prepare an Autism Emergency Bag

Keep a small emergency bag that can be taken quickly.

Consider including:

Disaster preparedness guidance for autistic families also emphasizes having emergency supplies, critical information, communication plans, and information about the child's individual needs ready before an emergency.

2. Create a One-Page Child Information Card

This can be extremely useful during an emergency.

Parents can prepare a card containing:

This card can be shown to healthcare workers, rescue personnel, teachers, volunteers, and other caregivers.

3. Prepare a Communication Plan

Parents should decide:

• Who will stay with the child?
• Where will the family meet if separated?
• Who should be contacted?
• How will the child communicate?
• What information should emergency workers know?

If mobile networks are unavailable, keep important phone numbers written on paper.

4. Plan the Evacuation Route

Families living in potentially vulnerable areas should identify:

• Safe higher ground where appropriate
• Official evacuation locations
• Alternative routes
• Family meeting points
• Places to stay temporarily

Do not wait until floodwater or a landslide is approaching to decide where to go.

Always follow official evacuation instructions.

5. Practice Before an Emergency

Children can benefit from simple practice.

Parents can practice:

Practice should be calm and age-appropriate.

The goal is familiarity, not fear.

DURING A DISASTER: What Parents Should Do

1. Physical Safety Comes First

Move away from danger according to official instructions.

Do not return to unsafe buildings, bridges, riverbanks, or roads simply to collect belongings.

After flooding, hazards may remain even when water levels fall.

2. Keep the Child Close

During evacuation:

• Stay physically close.
• Hold hands where appropriate.
• Use identification information.
• Keep the child's emergency bag nearby.
• Avoid leaving the child with unfamiliar people unless necessary and safe.

3. Use Short Instructions

Avoid long explanations during an emergency.

Use simple statements:

One instruction at a time may be easier to understand.

4. Reduce Sensory Overload

If possible:

• Move away from loud noise.
• Use headphones or ear protection.
• Reduce unnecessary physical contact.
• Keep a familiar comfort item nearby.
• Find a quieter area.
• Maintain a calm voice.

Do not punish a child for becoming distressed.

The behavior may be a response to fear or sensory overload.

5. Do Not Force Communication

A frightened child may communicate less than usual.

Do not repeatedly demand: “Tell me what happened.”

Instead, offer alternatives:

• Pointing
• Pictures
• Gestures
• Writing
• Communication devices
• Simple yes/no questions

Observe behavior carefully.

6. Inform Emergency Workers

Tell responders clearly:

Then explain the child's most important needs. For example:

Clear communication between families and responders is an important part of disaster risk reduction. UNDRR emphasizes that effective risk communication helps people understand risk and take appropriate action.

POST-DISASTER: THE PARENTAL GUIDE

The First Priority: Rebuild Safety

After reaching a safe location, parents should focus on:

Parents do not need to immediately restore everything exactly as it was before.

Start with the basics.

1. Re-establish a Simple Routine

Even if the family is living temporarily somewhere else, create a basic schedule.

For example:

A temporary routine can give the child some predictability when everything else has changed.

2. Watch for Behavioral Changes

After a disaster, parents may notice:

• More crying
• Increased irritability
• Withdrawal
• Increased repetitive behaviors
• Difficulty sleeping
• Changes in appetite
• Increased attachment to parents
• Fear of certain sounds
• Difficulty separating from caregivers
• More frequent meltdowns
• Temporary changes in communication

These changes can occur as a response to stress and disruption.

They should not automatically be interpreted as a permanent change in the child's autism or development.

3. Pay Attention to Non-Verbal Signs

A child who cannot easily explain how they feel may communicate through behavior.

For example:

• Refusing food
• Becoming unusually quiet
• Crying
• Holding a particular body part
• Changes in movement
• Changes in sleep
• Increased aggression
• Avoiding activities

Parents should consider whether the child may be experiencing:

• Pain
• Fear
• Hunger
• Thirst
• Exhaustion
• Sensory overload
• Anxiety

4. Protect Sleep

Sleep can be disrupted after disasters.

Try to recreate familiar sleep conditions where possible.

Use:

• Familiar blankets
• Familiar clothing
• A familiar bedtime routine
• Reduced noise
• Lower lighting
• Familiar bedtime activities

Even when the surroundings are temporary, maintaining a predictable bedtime sequence may help.

5. Maintain Medication

If the child takes prescribed medication, parents should try to maintain access and follow the prescribing professional's instructions.

Keep medication information together with the emergency documents.

If medication has been lost or supplies are running low, contact an appropriate healthcare provider.

Do not change or stop prescribed medication without professional medical advice.

6. Food and Sensory Needs Matter

Emergency food distributions may not always contain foods that an autistic child is comfortable eating.

If the child has strong food preferences or sensory-related feeding difficulties, parents should explain this to relief workers when possible.

A child who refuses unfamiliar food may not simply be “being difficult.”

Texture, smell, appearance, temperature, or unfamiliarity may affect acceptance.

Safe familiar foods can therefore be useful in an emergency kit.

7. Therapy May Be Interrupted

A disaster can temporarily interrupt:

• Speech therapy
• Occupational therapy
• Physiotherapy
• Behavioral intervention
• Developmental services
• School

Parents should not feel guilty if therapy cannot continue during the immediate emergency.

Safety comes first.

When services become available again, professionals can help the child return gradually to appropriate routines and developmental goals.

8. Returning to School

Returning to school can help restore normality, but it should happen when the environment is safe.

Teachers and parents should communicate about:

• Changes in the child's behavior
• Sleep problems
• Communication difficulties
• New fears
• Sensory difficulties
• Changes in routine
• Academic difficulties

A child may need additional time and support to adjust.

9. Talk About the Disaster Simply

Children may not understand what happened.

Use simple explanations. For example:

Avoid repeatedly exposing the child to frightening videos or graphic disaster images.

Give truthful information without unnecessary frightening details.

10. Allow Time for Recovery

Every child responds differently.

Some children may return to normal quickly.

Others may remain distressed for longer.

Parents should focus on:

• Safety
• Predictability
• Familiarity
• Connection
• Communication
• Rest
• Gradual return to everyday activities

Recovery does not need to happen all at once.

WHEN SHOULD PARENTS SEEK PROFESSIONAL HELP?

Parents should consider professional assessment if significant changes continue or interfere with the child's daily life.

Seek appropriate healthcare or developmental support if a child:

• Remains extremely distressed
• Has persistent sleep problems
• Stops eating or drinking adequately
• Shows a significant change in communication
• Loses previously acquired skills
• Becomes unusually withdrawn
• Shows persistent severe anxiety
• Has ongoing unexplained physical symptoms
• Experiences repeated severe behavioral episodes
• Cannot return to basic daily activities

SPECIAL CONSIDERATIONS FOR NON-VERBAL OR MINIMALLY VERBAL CHILDREN

Children who use little or no spoken language may require additional planning.

Parents should prepare:

This information can help unfamiliar people understand the child more quickly.

A SIMPLE “AUTISM DISASTER PLAN”

Parents can remember five key areas:

PARENT EMERGENCY CHECKLIST

What Parents Should Avoid

During and after a disaster, parents should try to avoid:

Why Nepal Needs Autism-Specific Disaster Preparedness

Disaster preparedness is often discussed at the level of households and communities.

However, children do not all experience emergencies in the same way.

Families of autistic children may require additional planning for:

• Communication
• Sensory needs
• Medication
• Food
• Identification
• Supervision
• Routine
• School continuity
• Therapy continuity
• Emotional recovery

Nepal's mountain geography makes disaster preparedness particularly important. Research by ICIMOD has documented significant exposure to glacial-lake and related mountain hazards, while recent events demonstrate how rapidly a mountain-origin disaster can affect downstream communities.

This does not mean that every mountain community will experience a major disaster.

It means that preparedness should be part of responsible family planning in areas where hazards are possible.

A Message for Parents

Key Takeaways

Conclusion

Nepal's unique geography means that mountain-related hazards such as flash floods, GLOFs, landslides, debris flows, and other cascading events can pose serious challenges to communities.

The 2026 Rasuwa disaster is a powerful reminder that mountain-origin hazards can affect communities far beyond their point of origin.

For families raising autistic children, disaster preparedness should include more than food, water, and shelter.

It should also include:

The goal is not to frighten parents.

The goal is to help them feel prepared.

A simple plan made before an emergency can reduce confusion when every minute matters.

And after the disaster, patience, routine, understanding, and appropriate professional support can help a child gradually regain a sense of safety.

Preparedness is not about expecting the worst.

It is about making sure that when something unexpected happens, your child is understood, protected, and supported.
