BANGKOK, Thailand, January 29 (IPS) – The international Year of glaciers’ Preservation in 2025 was a timely reminder that the stability of mongolia’s economy rests on fragile mountain systems that are melting faster then ever recorded. The loss reverberates across the country’s energy and agricultural systems, two development pillars that draw from the same finite resource: water.
Warming and glacial retreat

Mongolia’s average surface air temperature is already 2.3°C higher than the pre-industrial baseline, about 1.3°C above the global average. The most fossil fuel-intensive climate scenario (SSP5) indicates nearly 8°C of warming by the end of the century with the steepest increases expected in the northern and western provinces; home to the country’s glaciers.
These glaciers contribute more than 70 per cent of Mongolia’s freshwater, sustaining agriculture, hydropower, and domestic use. Since 1940, glacier volume has declined by about 28 per cent, and total glacier area has decreased by 35 per cent between 1990 and 2016, leaving only 627 glaciers covering 334 km.
Between the 1980s and 2010,Mongolia lost 63 lakes larger than 0.1 km and about 683 rivers,many in the foothills of the Altai ranges with the highest concentration of glaciers.Groundwater storage on the Mongolian Plateau is also decreasing at nearly 3 mm per year, linked partly to reduced glacial input.
Analysis using downscaled IPCC climate projections available on ESCAP’s Risk and Resilience Portal suggests that this trend is likely to continue in the coming decades and by 2,100 many western Altai glaciers may disappear entirely (Figures 1A and 1B).
Mongolia’s hydropower sector, which provides over 28 per cent of regional power but operates in one of the driest parts of the country.With glacier retreat and declining summer precipitation, inflows have become less predictable.
ESCAP drought-exposure modelling shows that the western provinces already face chronic low-to-medium drought intensity, with worsening conditions under future scenarios (Figure 3).

When summer river levels fall, reservoir storage drops, hydropower generation declines and diesel generation must fill the gap raising both costs and emissions. Simultaneously occurring, agricultural water withdrawals upstream further constrain available flows for power generation.
The result is a feedback loop: limited water cuts hydropower output, leading to higher reliance on fossil energy, which in turn intensifies warming and glacier melt.
Competing pressures in a semi-arid economy
In the Western Energy Systems, consisting of provinces closest to the glaciers, rising demand compounds these stresses. Between 2018 and 2019, electricity consumption in the region rose 5.6 per cent, driven by population growth and mining expansion.
In summer months, when electricity demand peaks for irrigation pumping and cooling, river discharge often reaches its lowest levels. This mismatch between energy demand and hydrological supply poses a systemic risk. Climate projections show that long-term discharge in key basins will decline, reducing the economic lifespan of existing hydropower assets.
Addressing this challenge requires coordinated planning across water,energy,and agriculture. Three areas stand out:
- Water-efficient agriculture.Expanding drip irrigation, adopting drought-resilient crop varieties, and improving on-farm water storage can reduce demand during low-flow periods. Aligning irrigation schedules with projected runoff cycles would ease pressure on hydropower reservoirs.
- Diversified renewables. Mongolia’s wind and solar resources can complement hydropower seasonality. Integrating hybrid systems with storage or pumped hydro can maintain grid stability during drought years.
- Data-driven basin management. Glacier monitoring and real-time hydrological data should inform both irrigation allocation and hydropower operation. This shared evidence-based approach can prevent conflicts between sectors

Melting Reserves of Power: Mongolia’s Glaciers and the Future of Energy and Food Security
The article highlights a critical issue: the rapid melting of glaciers in Mongolia, threatening both energy supplies (hydropower) and food security (water for agriculture). Given the date of the source (January 2026), a thorough update is crucial.
Mongolia’s Glacial Retreat and Climate change
Mongolia is experiencing accelerated glacial melt due to climate change, significantly impacting its water resources.Glaciers in the Mongolian Altai Mountains are particularly vulnerable. According to a 2022 study by the National University of Mongolia, the country’s glaciers have shrunk by 18% since 1976, and the rate of melting has increased dramatically in recent years. National University of Mongolia – Environmental Research Center. This trend is projected to continue, with perhaps devastating consequences.
Impact on Hydropower Generation
Hydropower is a significant component of Mongolia’s energy mix,providing approximately 20% of the country’s electricity as of 2023. Mongolian Ministry of Energy – Energy Sector Overview. glacial melt initially increases water flow, potentially boosting hydropower generation in the short term. Though, as glaciers shrink, the long-term affect is a reduction in water availability, leading to decreased hydropower output. A 2024 report by the Asian Development Bank (ADB) warns that several hydropower plants in Mongolia could face reduced capacity by 2030 due to declining glacial meltwater. Asian Development Bank – Mongolia Water Resources Assessment (2024).
Threats to Food Security and Agriculture
Mongolia’s agricultural sector is heavily reliant on glacial meltwater for irrigation,particularly in the western regions. Approximately 80% of Mongolia’s agricultural land is dependent on irrigation. FAO – Mongolia Country Profile.Decreasing water availability threatens crop yields and livestock production, exacerbating food insecurity. The Ministry of Food, Agriculture and Light Industry of Mongolia reported a 15% decrease in wheat production in 2025 due to drought conditions linked to reduced glacial meltwater. Mongolian Ministry of Food, Agriculture and Light Industry – Wheat Production Decrease (2025).This has lead to increased reliance on food imports.
Government Initiatives and Adaptation Strategies
The Mongolian government has implemented several initiatives to address the challenges posed by climate change and glacial melt. These include investments in water-efficient irrigation technologies, diversification of agricultural practices, and exploration of alternative energy sources. In February 2026,the government announced a national water resource management plan with a budget of $50 million USD,focusing on improving water storage and distribution infrastructure. Mongolian Government – National Water Resource Management Plan Approved (February 2026). Furthermore, Mongolia is actively seeking international cooperation and funding to support its climate adaptation efforts.
International Cooperation and Support
International organizations, such as the United Nations Surroundings Programme (UNEP) and the World Bank, are providing technical and financial assistance to Mongolia to address climate change impacts. The World Bank approved a $30 million loan in March 2026 to support Mongolia’s efforts to improve its water resource management and
