Four HKH countries recorded more than 10 major disasters in 2025

Kathmandu | 12 May 2026 – Four of the eight countries in the Hindu Kush Himalaya (HKH) region experienced more than 10 major disasters in 2025, according to data from ICIMOD analysis, highlighting the region’s growing exposure to hazard-related risks.

Asia accounted for a large share of disasters globally in 2025, a trend reflected in the HKH, which spans parts of South and East Asia. Analysis of EM-Data shows that countries in the HKH region experienced economic losses of more than USD $6 billion in 2024 alone from these events, with most damage linked to water-related hazards such as floods, landslides and storms.

The situation continued into 2025. Intense monsoon rainfall triggered repeated flooding and landslides across several HKH countries, including Bangladesh, India, Nepal, and Pakistan. Other hazards, such as glacial lake outburst floods, were also reported in select locations. Across the region, about 1.2 million people were displaced or directly affected by disasters during the year. 

Globally, disaster-related economic losses in 2025 were estimated at more than USD $169 billion. In comparison, losses recorded across the HKH highlight how extreme events translate into disproportionate impacts in a region characterised by complex terrain and high exposure. 

Data also shows that Myanmar, Pakistan, and China experienced a series of monsoon-induced floods in 2025, causing widespread damage to infrastructure and livelihoods. 

Researchers link the increasing impact of disasters in the HKH to the growing prevalence of multi-hazard events. Multi-hazards occur when more than one type of hazard, such as floods, landslides, or droughts, happen at the same time or when one hazard triggers another. Past examples in the region include the Kedarnath floods in Uttarakhand in 2013, and the South Lhonak glacial lake outburst flood in Sikkim in 2023, India, as well as the Melamchi flood in Nepal in 2021. 

“Recent years show how floods, landslides, and other hazards are increasingly overlapping in mountain regions, amplifying damages to homes, infrastructure, and essential services,” said Pema Gyamtsho, Director General at ICIMOD, commenting on the regional trend. 

Long-term data covering the period from 1975 to 2024 shows a decline in death rates and the number of people affected by disasters in the HKH after 2013. Analysts caution that data gaps may influence this trend, but improvements in preparedness and early warning systems may also be contributing factors. 

“The numbers are still worrying, but the post-2013 trend suggests fewer lives are being affected year on year, which may reflect better climate services and preparedness in parts of the region,” said Manish Shrestha, a hydrologist at ICIMOD. “Sustained investment in preparedness and planning remains critical as risks continue to rise.” 

Early warning systems have been credited with reducing losses in some flood-prone areas. In eastern Nepal, alerts issued from a flood early warning system along the Khando River in 2024 helped inform and evacuate around 60,000 people living downstream. 

Analysts note that reducing future disaster losses in the HKH will also depend on risk‑informed investments, where development and infrastructure planning take multi‑hazard risks into account. Without integrating hazard and vulnerability data into investment decisions, exposed communities risk locking in higher losses as climate‑driven extremes intensify. 

Experts warn that multi‑hazard risks are likely to intensify in the coming years as climate change alters weather patterns and increases the frequency and severity of extreme events, leaving exposed communities across the HKH vulnerable to escalating losses.
