The largest recent disaster losses

Which risks should be reduced before the next emergency, and who maintains the protection?

Place-specific evidence and policy choices. A budget promise is not a completed service; older figures retain their reporting period. Proposed options and indicators below are for public discussion, not adopted government commitments.

Which risks should be reduced before the next emergency, and who maintains the protection?1256

Updated 2026-10-13 · Version 1 · Sources · Change history

Question 1 What is the issue, and why does it matter?

On 26 August 2026 an ice-and-rock avalanche in the upper Lhende Khola watershed, about 20 km upstream of the Rasuwagadhi border point, sent a flood down the Bhotekoshi–Trishuli rivers. As of 3 October 2026 the disaster authority reported 1,455 deaths (including partial remains) and 5,285 people missing; it says these figures are provisional and may rise or fall. The government's rapid assessment puts total effects at NPR 408.29 billion and recovery needs at NPR 723.32 billion.12

The choice is how to improve outcomes in this province, who benefits first, and which institution can act. The figures below belong to the stated reporting period; they are not a real-time measure of today’s conditions.

Question 2 What do current law and policy say?

Water supply is a provincial and local service (Schedule 6, item 7; Schedule 8, item 19) and federal–provincial concurrent with sanitation (Schedule 7, item 18); human settlement and land-use policies are federal (Schedule 5, item 29); local development plans are local (Schedule 8, item 7).3

Disaster preparedness, relief and recovery is federal–provincial concurrent (Schedule 7, item 17), a local power (Schedule 8, item 20) and concurrent for all three levels (Schedule 9, item 9).3

Provincial executive power rests with the Council of Ministers. The Chief of Province (governor) performs constitutional and legal functions, generally on the Council’s recommendation and consent; the governor is not the department delivering these services. Provincial revenue and expenditure estimates go to the Provincial Assembly.4

Question 3 What is known, uncertain or disputed?

Known

On 26 August 2026 an ice-and-rock avalanche in the upper Lhende Khola watershed, about 20 km upstream of the Rasuwagadhi border point, sent a flood down the Bhotekoshi–Trishuli rivers. As of 3 October 2026 the disaster authority reported 1,455 deaths (including partial remains) and 5,285 people missing; it says these figures are provisional and may rise or fall. The government's rapid assessment puts total effects at NPR 408.29 billion and recovery needs at NPR 723.32 billion.12

In the September 2024 floods and landslides, Nepal Police data compiled by the disaster authority recorded 161 incidents and 208 of the 238 deaths nationwide in Bagmati (preliminary figures). Kavrepalanchok alone had 3,121 houses fully destroyed. The authority's report links the severity of flooding in Kathmandu Valley to rapid urban growth and inadequate drainage.5

The provincial FY 2083/84 budget, presented before the 2026 flood, allocated funds for embankments, risk reduction, reconstruction, disaster volunteers and disaster insurance.6

Uncertain

A province-wide number does not identify the worst-served wards or prove the same problem in every municipality. Before spending, establish a current local baseline, service quality, staffing, access barriers and the full operating cost.

Disputed

The policy choice is how to balance universal access, concentrated investment, affordability and fiscal sustainability. The alternatives below are Policy Nepal’s discussion options derived from the problem evidence, not claims that officials or parties have endorsed them.

Questions 4–5 What are the options, and what do they cost and achieve?

Options are listed in no particular order. Policy Nepal does not recommend one; real policies often combine them.

Prioritise preparedness and existing assets1256

Map exposed settlements and essential facilities; clear drainage, stabilise critical slopes, maintain evacuation routes and practise warnings people can act on.

Benefits
  • Focuses limited resources on reducing exposure and keeping services working.
Costs
  • Risk mapping, local teams, maintenance and accessible warnings require regular funding.
Trade-offs
  • Warnings do not make an unsafe home or road safe; households may need relocation support.
What does implementation require?
  • Assign named offices for each critical asset, test warning reach and publish drill findings without exposing vulnerable households.

Build safer reconstruction and basin-wide protection1256

Rebuild to verified safety standards and coordinate river, road and settlement interventions across municipal boundaries.

Benefits
  • Can reduce repeated losses and restore access to schools, clinics and markets.
Costs
  • Requires design review, skilled supervision, land agreements and long-term maintenance.
Trade-offs
  • An embankment can shift flood risk elsewhere; resettlement must protect livelihoods and rights.
What does implementation require?
  • Publish hazard assumptions, affected-household consultation, inspection results and a funded maintenance plan before declaring completion.

Combining options

Start with a verified baseline and maintenance of functioning services, then test additional investment against the same outcomes. Publish who pays for capital costs, recurring costs and any household charges; an unfunded operating plan is not a sustainable solution.

Question 6 Who is responsible?

Shared
Urban services, water and drainage

Water supply is a provincial and local service (Schedule 6, item 7; Schedule 8, item 19) and federal–provincial concurrent with sanitation (Schedule 7, item 18); human settlement and land-use policies are federal (Schedule 5, item 29); local development plans are local (Schedule 8, item 7).3

Shared
Disaster risk and recovery

Disaster preparedness, relief and recovery is federal–provincial concurrent (Schedule 7, item 17), a local power (Schedule 8, item 20) and concurrent for all three levels (Schedule 9, item 9).3

Provincial
Chief Minister, Council of Ministers and Provincial Assembly

Provincial executive power rests with the Council of Ministers. The Chief of Province (governor) performs constitutional and legal functions, generally on the Council’s recommendation and consent; the governor is not the department delivering these services. Provincial revenue and expenditure estimates go to the Provincial Assembly.4

Question 7 What have parties and leaders said and done?

What was said or promised is shown apart from what was recorded as done. Every entry needs a dated source. A missing entry means the position is not established, not that someone opposes or is neutral.

This dossier presents official evidence and research options. It does not assign a position to a chief minister, governor, mayor or political party without a dated source specific to this issue.
