ROME, February 12 (IPS) – Glaciers – the world’s hidden water banks – are a supply of life for billions. The seasonal soften from mountains and glaciers sustains a number of the world’s most vital rivers, such because the Indus, the Nile, the Ganges and the Colorado. These and different mountain-fed rivers irrigate crops, present ingesting water for practically two billion folks, and energy electrical energy era.
However, as glaciers shrink and vanish, modifications in water flows pose a rising threat to the water, meals and livelihood safety of billions of individuals.
Within the quick time period, accelerated melting can set off environmental hazards: flash floods, glacial lake outburst floods, avalanches and landslides.
In the long run, the glaciers as water sources will merely disappear.
By century’s finish, most glaciers will contribute far much less water than they do immediately, undermining agriculture in each mountain villages and sprawling lowland breadbaskets downstream.
Mountains cowl greater than 1 / 4 of the world’s land and are dwelling to 1.2 billion folks, however these areas are heating up extra quickly than the worldwide common. Mountain communities are particularly susceptible to growing local weather variability and lowering seasonal water availability for agriculture and irrigation. With usually no viable different water provide, the lack of agricultural manufacturing can result in local weather displacement and larger instability.
5 of the previous six years have seen probably the most fast glacier retreat on file, and the impacts are already being felt.
Communities from the Andes to the Himalayas are experiencing shorter snow seasons, erratic runoff, and the lack of dependable water. In Peru, dwindling glaciers have slashed crop yields. In Pakistan, diminished snowmelt threatens seasonal planting cycles. Many glaciers have already reached or are anticipated to achieve “peak water” – the purpose at which meltwater runoff is at its most, after which flows will step by step decline – within the coming two or three many years. This implies everybody who is dependent upon glacier-fed rivers faces growing shortage when inhabitants development will push water demand even larger.
Past science and survival, the disappearance of glaciers erases one thing much less tangible however equally profound. For Indigenous Peoples and mountain communities throughout Asia, Latin America, Africa and the Pacific, glaciers are sacred. Their melting erodes traditions, rituals, identification and cultural heritage certain to mountain landscapes for hundreds of years.
Whereas there may be nonetheless time to behave, world responses stay fragmented and insufficient. That’s why the United Nations declared 2025 the Worldwide Yr of Glaciers’ Preservation – a transparent reminder that preserving these frozen ecosystems means defending our future.
To make sure meals and water safety from the peaks to the plains, a daring shift in coverage, funding and governance is urgently wanted.
Broadly talking, chopping greenhouse fuel emissions, bettering water administration, and strengthening early warning techniques, adaptative agriculture and sustainable agrifood techniques are crucial.
We have to flip the challenges posed by melting glaciers into alternatives to the advantage of all.
Agriculture, each a significant water person and a key sector for adaptation, can itself be an answer when developed sustainably. Methods like terrace farming, agroecology, agroforestry and crop diversification – practiced by mountain communities for hundreds of years – assist protect soil and water, scale back catastrophe threat and help livelihoods. Such adaptation efforts must be inclusive, drawing on Indigenous Peoples’ information and addressing root vulnerabilities like poverty and gender inequality.
We should additionally mobilize investments in water and agricultural infrastructure. This consists of extra local weather finance to help susceptible mountain communities that wrestle to entry coaching, funding and innovation.
As well as, governments have to align methods, insurance policies and plans to handle this important nexus between water, agriculture and local weather resilience. Mountains are sometimes absent from nationwide local weather insurance policies and world adaptation frameworks. We want insurance policies and collaboration that tackle glacier-fed water techniques, cross-border cooperation, and risk-sharing and early warning mechanisms – particularly as rivers fed by glaciers usually span a number of international locations. This additionally consists of reviewing basin-wide water allocation methods, plans and funding in infrastructure to enhance water use effectivity, and step up glacier monitoring and analysis.
Making ready for a world with fewer glaciers and fewer of their valuable water requires innovation and coordination. In Kyrgyzstan, FAO has been serving to consultants assemble synthetic glaciers – ice towers created by spraying mountain water and that step by step soften in summer season. Within the area of Batken alone, this initiative has helped retailer over 1.5 million cubic meters of ice, sufficient to irrigate as much as 1,750 hectares.
In Ladakh, India, the social enterprise Acres of Ice has developed automated ice reservoirs to seize unused water in autumn and winter and freeze it till spring. Within the Peruvian Andes, a community-based initiative is addressing the deterioration of water high quality from minerals uncovered by receding glaciers by a pure filtration system utilizing native vegetation.
However much more must be achieved, collectively. Glaciers matter as a result of water issues. To disregard their fast retreat is to gamble with world meals and water safety.

FAO is remitted to guide the worldwide observance of Worldwide Mountain Day, coordinated by the Mountain Partnership Secretariat, which is financially supported by the governments of Italy, Andorra and Switzerland. The Secretariat collaborated carefully with UNESCO and the World Meteorological Group, co-facilitators of the Worldwide Yr of Glaciers’ Preservation 2025.
