The Hindu Kush Himalayas are experiencing more frequent and severe floods, landslides, and avalanches due to environmental changes. The ICIMOD monitors these threats to millions of people in the region.
Nepal came under the sudden force of a massive flood on Wednesday, leaving a trail of devastation as the Himalayan fury claimed at least 165 lives and left more than 1300 people missing. The Himalayan nation’s northern region bore the brunt of the disaster, with Rasuwa district on China-Nepal border among the worst-hit areas. The fury was carried by the Bhote Koshi River, which originates in Tibet and came rushing down with enormous force, carrying with it ice, rocks, mud and debris.
The aftermath offers a stark picture of the destruction left behind. Villages appear wiped out, roads have vanished and entire stretches of civilisation seem to have been swept away by nature’s fury. Nuwakot, barely 50 kilometres and around a two-hour drive from Rasuwa, bears the deadly imprint of the floods. The river appears to have changed course, pushing aside the settlements that once stood along its path and spreading a vast stretch of muddy debris across the landscape. The flood tore through the Sino-Nepalese border region, destroying almost everything in its way, sweeping away vehicles, ripping apart roads and engulfing entire villages in the northern Himalayan region. The debris that ravaged Rasuwa and surrounding areas was a deadly mix of ice, rock and mud that rushed into the Bhote Koshi River, turning it into a torrent of destruction.
The scale of the disaster also highlights a wider and growing threat facing the Hindu Kush Himalayas. Floods, landslides, avalanches and droughts are becoming more frequent and severe across the region, while rapid changes to water, land and air are posing a major threat to millions of people, according to the International Centre for Integrated Mountain Development (ICIMOD). The organisation said on Wednesday that the flash flood sent a powerful surge of water, sediment and boulders through the Bhote Koshi and Trishuli river systems. In the downstream Galchhi area, water levels in the river reportedly rose by as much as nine metres, nearly 30 feet, in just 30 minutes.
A 460-acre former dairy farm in Somerset, UK, has seen a surge in biodiversity since being acquired by the charity Heal in 2022. Three years into its rewilding project, bird species counts rose from 67 to 94, and butterfly species more than doubled from 11 to 24.
Flash floods in Nepal, resulting in 162 deaths and 750 missing, were caused by a glacial collapse in Tibet rather than an earthquake. The US Geological Survey confirmed the origin, noting that 133 Indian nationals are among those missing.

नेपाल के रसुवा और आसपास के जिलों में आई भीषण बाढ़ के बाद विशेषज्ञ हिमालयी क्षेत्र की भौगोलिक बनावट, ग्लेशियल झीलों के फटने और हिमस्खलन को इसका मुख्य कारण मान रहे हैं। सीमा पार तिब्बती क्षेत्र से उत्पन्न होने वाली ये आपदाएं नेपाल के बुनियादी ढांचे के लिए बड़ा खतरा हैं।
Water levels in the Gandak river are receding in Bihar following flash floods in Nepal. Discharge from the Valmikinagar barrage has decreased from its peak, though officials remain vigilant due to ongoing rainfall in Nepal and monitoring of the Ganga river.
