KATHMANDU — The United Nations and humanitarian partners have launched a $49.6 million emergency appeal to provide life-saving assistance to more than 84,000 people affected by catastrophic flash floods and landslides in northern Nepal.

The disaster, which struck on August 26, devastated communities across the region, destroying homes, roads and other critical infrastructure and leaving thousands of people in urgent need of humanitarian assistance. The UN humanitarian community said the appeal is aimed at supporting those most severely affected by the disaster.

The emergency response is focused on providing essential supplies and services, including food, clean water, emergency shelter, healthcare and protection assistance for affected communities.

The scale of the disaster has also placed enormous pressure on Nepal’s search-and-rescue operations. According to Nepalese authorities cited by Reuters, more than 1,294 people have been killed, while thousands remain missing following the floods and landslides.

The disaster caused particularly severe damage along the Trishuli River, where floodwaters, rocks, mud and debris swept through communities and infrastructure. Hydropower facilities and access roads were also heavily damaged.

Rescue teams have continued searching for survivors in areas cut off by the disaster. In a dramatic development, two workers were rescued alive from a hydropower tunnel nine days after the disaster struck.

The humanitarian crisis is compounded by the destruction of homes and basic infrastructure. Nepalese officials have estimated that thousands of houses will need to be rebuilt, while overall property, housing and infrastructure losses have reached billions of dollars.

The UN and its humanitarian partners say the immediate priority is to reach people who have lost their homes and livelihoods and to prevent further suffering as recovery efforts begin.

The emergency appeal will support relief operations in the hardest-hit communities and help humanitarian agencies deliver assistance to people who urgently need it.

The disaster is among the most serious natural emergencies Nepal has faced in recent years, with the effects extending beyond immediate loss of life to homes, livelihoods, transportation networks and vital infrastructure.

As search-and-rescue operations continue, the United Nations is urging international support for the emergency response and emphasizing the urgent humanitarian needs of tens of thousands of survivors.

Shibbir Ahmed, United Nations, New York: The death toll from devastating flash floods and landslides in Nepal has risen to 538, while nearly 1,000 people remain missing. Many of those missing are believed to be tourists. Search and rescue operations and relief efforts continue across the disaster-hit areas.

On Friday, citing figures from the Government of Nepal, the UN Office for the Coordination of Humanitarian Affairs (OCHA) said nearly 3,750 people had been rescued following the disaster. Rescue teams are continuing efforts to reach people stranded in various parts of Nepal’s Rasuwa, Nuwakot and Dhading districts.

According to the latest update issued Friday by Nepal’s Ministry of Foreign Affairs, 538 bodies have so far been recovered from the flood-affected areas. The ministry also said that among 632 foreign nationals from 33 countries, 121 have been located or accounted for, while 511 remain missing. The figures are expected to change as search and rescue operations continue.

Glacier Collapse Believed to Have Triggered Disaster

A devastating flash flood struck the Bhote Koshi River area of Nepal on August 26. The disaster is believed to have been triggered by a glacier collapse and subsequent landslide, sending huge amounts of water, rocks, mud and debris rapidly down mountain waterways.

Entire communities were destroyed by the powerful floodwaters, while roads, bridges, hydropower facilities and other critical infrastructure suffered extensive damage. Rasuwa is among the worst-affected districts. Rescue operations have been particularly challenging because of the mountainous terrain, damaged roads and disrupted communications.

Tibet Also Severely Affected

China’s Tibet Autonomous Region, on the other side of the Nepal-China border, has also been severely affected by the disaster. According to authorities there, around 560 people remain missing. Officials fear the number of casualties and missing people could rise as search operations continue in both Nepal and Tibet.

Renewed Flood Threat

The situation became even more dangerous after a new water reservoir or lake formed in the mountainous region following the initial flooding. On Friday, rising water levels raised fears of another flood, temporarily disrupting rescue operations in some areas. Rescue efforts resumed after the immediate threat was brought under control. Nepalese authorities continue to monitor river levels and the risk of further flooding downstream.

UN Supports Relief Efforts

UN agencies are working to deliver emergency food, medical supplies, tents and other assistance to communities affected by the disaster. The United Nations said it is providing medical supplies sufficient for around 10,000 people for three months, along with emergency food rations, tents and logistical support. Satellite imagery is also being used to assess and monitor the affected areas.

Lila Pieters Yahia, the UN Resident Coordinator in Nepal, visited the disaster zone. She described the rescue of an entire family as an extremely emotional moment. Her visit was cut short after a renewed flood alert was issued.

Risk of Disease Outbreaks

The World Health Organization (WHO) has warned of an increased risk of infectious diseases following the disaster. WHO spokesperson Tarik Jašarević said that when disasters of this scale cause displacement and overcrowding, while disrupting water, sanitation and health services, the risk of infectious diseases can increase significantly.

Dozens of Schools Destroyed

The UN Children’s Fund (UNICEF) said 18 schools have been completely destroyed and another 20 have been damaged by the floods. Dozens more schools located near riverbanks remain at high risk. As a result, an estimated 10,000 school-aged children in the affected areas need support to continue their education.

‘The Impact Is Truly Immense’

Kamal Kishore, head of the UN Office for Disaster Risk Reduction (UNDRR), highlighted the extraordinary scale of the disaster. He said that, in living memory, such a major mountain hazard event had not been seen for a very long time.

The disaster has had an immense impact on lives and livelihoods, as well as buildings, bridges, infrastructure, hydropower projects and power generation facilities, he said. Kishore added that authorities and humanitarian agencies are still trying to understand the full extent of the damage.

He described the current situation as involving both extremely high risk and significant uncertainty, stressing that the emergency itself is not yet completely over. The UN said the disaster has once again highlighted the fragility of mountain ecosystems and the challenges of establishing effective early-warning systems in mountainous environments.

More Than 93,000 People Affected

The International Federation of Red Cross and Red Crescent Societies (IFRC) said it is “very, very concerned” about the possibility of a secondary flood. According to the organization, at least 93,000 people have been affected by the disaster and are in urgent need of assistance.

Nepal’s Ministry of Foreign Affairs said security and disaster-management agencies are operating at full capacity to support search and rescue, medical assistance, evacuation and relief operations in the affected areas.

Region Has Faced Major Disasters Before

The disaster-hit region has experienced major natural disasters in the past. In April 2015, a magnitude 7.8 earthquake struck Nepal, killing more than 8,800 people. Last October, torrential rains triggered flash floods and landslides across parts of eastern and central Nepal, affecting more than 30,000 people.

The latest disaster is being viewed as one of the most severe natural disasters to hit Nepal in recent years. The death toll and number of missing people could change as search and rescue operations continue.
