Central Asia is emerging as one of the regions most vulnerable to drought, according to the latest Global Drought Outlook published by the United Nations.
A Region Under Climate Pressure
The report highlights a persistent rise in average annual temperatures, diminishing snow cover, and accelerated glacier retreat, particularly in the mountainous regions of Tajikistan and Kyrgyzstan, as key drivers of water insecurity.
“Climate change is accelerating glacier retreat… This poses a long-term threat to the region’s water security,” the report states.
Tajikistan, which holds over 60% of Central Asia’s glaciers, plays a critical role in the region’s hydrology.
Agriculture on the Brink
The first sector to suffer from prolonged drought is agriculture, which underpins food security across Tajikistan, Uzbekistan, and Turkmenistan. Most agriculture in these countries relies on outdated irrigation systems ill-equipped to handle evolving climate conditions.
According to the Food and Agriculture Organization (FAO), the global incidence of droughts rose by 29% between 2000 and 2023. In Central Asia, this trend has resulted in declining crop yields, income losses, and forced livestock sales.
In Tajikistan’s Khatlon and Sogd regions, farmers experience income drops of 15-30% during dry years. Despite generating more than 60% of the region’s freshwater through glaciers and high-altitude rivers, Tajikistan struggles with its own water shortages. Nearly 60% of water is lost due to leakage in dilapidated canals, compounded by inefficient water management. Rural communities are particularly affected, with thousands of families lacking regular access to clean water.
Hydropower and Economic Risks
Tajikistan relies on hydropower for over 90% of its electricity. However, inconsistent snowfall and prolonged summer droughts have drastically lowered reservoir levels, threatening national energy stability. More than half of the country’s 14,000 kilometers of irrigation canals require modernization.
From 2000 to 2016, drought-related economic losses in Central Asia exceeded $2 billion. In 2023 alone, Tajikistan incurred $5.4 million in damages due to power shortages.
Droughts are also impacting public health, employment, and migration. Natural disasters annually affect around 1.4 million people in Uzbekistan and 500,000 in Kazakhstan and Tajikistan. By 2050, drought-related losses are expected to reach 1.3% of regional GDP annually, with up to five million climate migrants projected.
Regional and Global Responses
Tajikistan, a signatory to the UN Convention to Combat Desertification, is pursuing land restoration and sustainable water management projects. Under the ISCAUZR-2 initiative (Central Asian Initiative on Sustainable Land Management), the country secured nearly $1.5 million to support sustainable agricultural practices.
Efforts include the development of fruit tree nurseries, installation of drip irrigation systems, construction of freshwater reservoirs, and deployment of monitoring sensors at water sources. Agroforestry techniques and drought-resistant crop varieties are also being introduced.
Despite these initiatives, the region continues to face rising temperatures, Asia has already surpassed a +1.04°C increase and Tajikistan has lost more than 1,000 glaciers. An estimated 10 million people across Central Asia lack sustainable access to safe drinking water.
Natural phenomena increasingly compound one another: droughts cause dust storms, which in turn accelerate glacier melt.
The UN report warns that without systemic investment in water infrastructure, enhanced agricultural resilience, and deeper regional cooperation, Central Asia will confront severe socio-economic disruption. It stresses that urgent action is needed at both national and international levels to address the looming water crisis.
