In the Upper Mustang region of Nepal, at almost 4,000 meters above sea level, the life of Buddhist villages followed an ancient rhythm. Yak and sheep herding, along with barley harvesting, set the daily pace beneath mountains pierced by millennia-old caves. However, water began to scarce and everything changed.
The springs dried up and the eternal snows receded, dyeing a once white landscape brown. The increasingly intense and erratic rains swept away fields and collapsed houses. Thus, families began to abandon their homes in search of a possible future.
What was once a vibrant community turned into a collection of crumbling houses, broken terraces, and empty shrines. The water crisis forced those who had inhabited those mountains for generations to migrate.
The mountainous regions of the Hindu Kush and the Himalayas, where the largest ice reserve on the planet after the poles is concentrated, are witnessing the disappearance of their glaciers. These ecosystems supply water to nearly two billion people, and their retreat jeopardizes the lives of entire communities.

Mountains Change with the Climate
Global warming is advancing faster in high mountain areas. Glaciers are retreating, permafrost is melting, and precipitations are becoming irregular. The consequences are direct: agricultural crises, lack of drinking water, and displacement of populations.
In places like Samjung, the water scarcity forced its inhabitants to seek new lands. The lack of snow affects agricultural production and compromises livestock breeding, leading families to make difficult decisions to survive.
This phenomenon is replicated in various parts of the world, where climate change forces entire communities to leave their homes. In the Himalayas, the main trigger is the lack of water, a resource increasingly scarce due to ice reduction and altered rainfall patterns.
The Challenges of Starting Anew
Relocating a village is not easy. Samjung needed a place with stable access to water, proximity to trade routes, and neighboring communities. Thanks to local agreements, families were able to settle near the Kali Gandaki River, where they rebuilt their homes and irrigation systems.
While some maintain their traditions, such as herding, others have adapted their economy to tourism, taking advantage of the proximity to Lo Manthang, a medieval city that attracts visitors interested in Buddhist culture and hiking.
Although the move allowed them to secure water access, many inhabitants still feel the loss of their ancestral home. The climate-induced transformation left deep scars on their history and cultural identity.

The Climatic Conditions of the Hindu Kush and the Himalayas
The Hindu Kush and the Himalayas are mountain ranges with extreme and changing climates. On their peaks, temperatures can drop below -30°C, while in the valleys, variations are intense. Precipitations, which used to be snow, now alternate between torrential rains and prolonged droughts.
The retreat of glaciers is altering river flows and affecting the water security of millions of people. Monsoon rains, intensified by climate change, cause floods and landslides, increasing risks for local communities.
Climate instability affects agriculture, trade routes, and food security, making mountainous regions particularly vulnerable to climate change. Adapting to these new scenarios is an urgent challenge for the populations living at these heights.
The silent drama of the Himalayan mountains is a global warning: when the climate changes, life changes. And in the heights, those changes arrive first and hit hardest.
