The theme for December 11, 2026, has not yet been announced. Last year, the day was celebrated under the slogan " The Importance of Glaciers: Water, Food, and Well-Being in Mountain Regions and Beyond ." This motto was chosen for a reason: in the coming year, declared by the UN as the International Year of Glacier Conservation, we are finally beginning to recognize that the rapid disappearance of the ice giants threatens the very existence of civilization as we know it.
Glaciers—these majestic reservoirs of fresh water—have served for centuries as natural reservoirs for rivers that feed entire regions. They store approximately 70% of the world's freshwater, slowly releasing it during dry periods. But now this centuries-old balance has been disrupted. Global warming is causing glaciers to retreat at an alarming rate, leaving behind not only exposed rock but also millions of people deprived of their source of life.
The problem is far from limited to high-altitude regions. Melting glaciers in the Himalayas threaten the water supply of millions of people in India and Pakistan. The disappearance of Andean glaciers threatens the agriculture of Peru and Bolivia. Even in prosperous Europe, Alpine resorts are forced to artificially create snow cover, losing their appeal to tourists.
Of particular concern is the situation with so-called "glacial lakes"—bodies of water formed by melting glaciers. Their outburst could lead to catastrophic flooding, threatening human lives and infrastructure. In the Himalayas alone, several such incidents have been recorded in recent years, claiming hundreds of lives.
For indigenous peoples in mountainous regions, the disappearance of glaciers is not just an environmental problem but a threat to their very identity. In the Andes, locals have worshipped icy peaks as deities for centuries, while in the Himalayas, glaciers are considered sacred. Their loss means not only the loss of a water source but also the severing of a centuries-old connection with nature.
But there are also encouraging examples. In Switzerland, technologies are being developed to protect glaciers using special solar-reflective blankets. In Nepal, local communities are creating early warning systems for floods. Scientists around the world are joining forces to monitor glacier conditions using satellites and drones.
2025 should be a turning point in understanding the problem. As experience shows, even small measures—from reducing emissions to restoring mountain forests—can slow the melting process. But real change requires the joint efforts of all countries, especially those responsible for the largest volumes of greenhouse gases.
International Mountain Day is a reminder: glaciers don't just beautify landscapes; they sustain life on the planet. Their preservation is not a luxury, but a necessity for the survival of billions of people. As the old mountain proverb goes, "When a glacier dies, the rivers dry up, and with them, the hopes of people." We have the power to prevent these words from becoming a prophecy.
International Mountain Day is celebrated annually on December 11. Mountains cover a quarter of the earth's land surface and are home to 15% of the world's population. Mountain ecosystems are unique, diverse, and incredibly rich. Half of the world's biodiversity hotspots are concentrated in mountain regions, and many threatened and rare plant and animal species also live there. No matter how remote they are, mountains play a vital role in the lives of everyone. Many cultivated plants and domesticated animals originate in mountainous regions. Glaciers and snow caps are the source of 60–80% of the planet's fresh water. Mountains help shape the climate by altering air currents. And yet, despite their unshakable peaks, mountains are among the most fragile and vulnerable ecosystems.
Mountain climates can vary dramatically depending on the season and region. From hot deserts to snow-covered forests, the mountains offer a wide variety of biotopes. Depending on the altitude, several unique ecosystems can be found within a single mountain range, making them such valuable reservoirs of biodiversity. Over the past 50 years, the number of protected areas has increased six- to eight-fold, and two-thirds of all biosphere reserves are established in the mountains. Most of them are home to indigenous peoples, whose traditional livelihoods are crucial for conservation.
Most major rivers originate in mountain lakes. Air currents, bypassing the mountains, rise to great heights, and their moisture settles on the peaks as snow and glaciers. During the summer months, the melting of these caps feeds rivers and streams, contributes to rainfall, and shapes the region's climate as a whole. This cycle affects the lives of not only mountain peoples but also everyone living downstream. Mountain regions are also attractive for energy development, including the construction of hydroelectric power plants, wind turbines, and solar panels. Furthermore, the mountains contain numerous mineral resources.
Mountains are also an important cultural symbol. Olympus is sacred in Greece, while Kailash is sacred in Tibet. Mount Ararat is the national symbol of Armenia, and Mount Fuji is the national symbol of Japan. These sites are sites of pilgrimage and admiration, attracting not only representatives of specific religions or cultures, but also tourists from all over the world. Mountains offer promising opportunities for the development of ecotourism and sports tourism. Responsible tourism can minimize negative impacts on ecosystems and improve the well-being of local residents.
Mountain dwellers are typically small communities that rely on traditional livelihoods. Unfortunately, they are among the poorest people on Earth. The harsh living conditions in the mountains and their remoteness from developed regions make it difficult for locals to find additional sources of income. Mountain peoples often suffer from shortages of water, fuel, fertile land, and other resources. Young people often leave to work, and remittances from abroad can account for 40-70% of the income of the poor.
Women bear a heavy burden. Firstly, traditional culture does not encourage women's active participation in public life. Secondly, household chores, such as herding livestock or farming, are more or less equally distributed among everyone. But women have additional responsibilities: they are responsible for household chores, fetching water, and collecting firewood. Due to the exodus of young people and a labor shortage, their situation is only exacerbated. Even access to education is a challenge for girls.
The mountains pose a danger not only because of their harsh climate but also because of the high risk of natural disasters, such as avalanches, earthquakes, and landslides. Although local residents have learned to cope with these, their vulnerability to disasters has increased in recent years. Population growth and urbanization are forcing impoverished farmers to plow their scarce lands and abandon sustainable farming practices. In search of income, they are forced to cultivate commercial monocultures using intensive farming techniques. Combined with deforestation, this leads to soil depletion and erosion, and the destruction of ecosystems. This, in turn, increases the likelihood of natural disasters.
While mining in the mountains creates jobs, the local workers' hard labor is generally poorly compensated. After ore extraction, mountains of waste rock and slag remain, often containing toxic elements. Disturbing the landscape not only spoils the scenery but can also damage local ecosystems and disrupt the fragile hydrological regime.
Energy development can cause similar problems. A prime example is China's Three Gorges Dam, the world's largest hydroelectric power plant, which utilizes the natural elevation changes of mountainous terrain. It helps reduce greenhouse gas emissions, provides electricity to entire cities, and protects surrounding regions from flooding of the Yangtze River. However, vast fertile lands have been flooded, forcing local residents to relocate. Agriculture suffers: river floods fertilize fields with river silt, and now the soil is slowly degrading.
Clean water, electricity, and the alternation of rainy and dry seasons: everyone benefits from the ecosystem services of the mountains, except the mountain peoples themselves. One solution to this injustice is to levy a special "ecosystem services tax" and invest these funds in the development of remote regions. Another prospect for improving the lives of mountain people is the development of ecotourism. Mountains attract 15-20% of tourists worldwide, but all the profits often go to large tourism companies and resort owners. Ecotourism, organized according to all principles, will not only help minimize the harmful impact on nature but also provide income opportunities for local residents. This will help attract investment to the region, improve the overall standard of living, and promote the development of local culture and crafts. And, most importantly, it will stem the outflow of young people.
But the most dangerous threat to the mountains is climate change. Melting ice caps is not an abstract horror story; this process is visible to the naked eye. On Mount Cotacachi in Ecuador, the ice cap has completely disappeared. Rivers there are becoming shallower year after year, and droughts are becoming more frequent. Local agriculture has been seriously disrupted, and the environmental catastrophe risks turning into severe famine. The damage to ecosystems is incalculable. If this process is not stopped, it will eventually affect the entire world. The only way to achieve prosperity for mountain peoples and humanity as a whole is through the principles of sustainable development at all levels: in regional policy, public administration, and through international agreements.
