New Drought Monitoring System Could Save Tajikistan Millions
Tajikistan stands to save between $4 million and $6 million annually by adopting a satellite-based drought monitoring system designed to reduce crop losses and improve water management.
Regional Project Launch
On August 20, a major regional initiative to monitor droughts in Central Asia was launched in Tashkent. The project, spearheaded by the United Nations Economic and Social Commission for Asia and the Pacific (ESCAP), will employ Earth Remote Sensing (ERS) technologies. The budget for the first phase is $300,000.
The system will initially be piloted in Uzbekistan for two years, with implementation in Tajikistan and Kyrgyzstan expected by 2027.
According to project analysts, Tajikistan’s annual savings will come from reduced agricultural losses, more efficient water use, and timely responses to drought conditions.
Agriculture at High Risk
Climate change poses a significant threat to Tajikistan. Over the past three decades, average temperatures in Central Asia have risen by 1.2°C, well above the global average of 0.85°C. Meanwhile, precipitation has decreased by 15-20%, increasing the frequency and severity of droughts.
Agriculture accounts for 22% of Tajikistan’s GDP, and approximately 1.5 million people — 15% of the population — live in drought-prone areas. The country’s mountainous landscape and limited water resources further magnify the impact of even minor climate shifts.
Current meteorological stations lack the capacity to monitor local variations. Weather conditions in mountainous areas can differ dramatically over short distances, rendering traditional methods insufficient.
The new system will rely on satellite data from Europe’s Sentinel-2 and the U.S.’s Landsat-8. These satellites measure the normalized difference vegetation index (NDVI), soil moisture, and surface temperature. Forecasts are updated every 5-10 days and have an accuracy rate of 80-85%. This will enable farmers to better plan irrigation schedules, select suitable crops, and conserve water resources.
Implementation Timeline
The initiative builds on a 2024 pilot project that developed monitoring methodologies and collected baseline data. In 2025, trials began in Uzbekistan (in Karakalpakstan and the Fergana Valley). Nationwide implementation in Uzbekistan is scheduled for 2026, followed by rollout in Tajikistan and Kyrgyzstan in 2027.
As part of the program, 150 specialists will be trained, and satellite data will be integrated into national meteorological systems.
Tajikistan is expected to cut annual crop losses by 10-15%, boosting food security and delivering $4-6 million in economic benefits. The project also aims to mitigate social pressures in rural areas.
In Uzbekistan, similar climate stresses displaced an estimated 120,000 people between 2018 and 2023 due to water shortages. By reducing drought-induced income loss, the system could help slow climate-related migration in Tajikistan as well.
The initiative draws on successful international models. Australia’s Drought Watch program has cut agricultural losses by 12%, while India’s INSAT-3D satellite has improved forecast accuracy to 78%. Both approaches will be adapted for Central Asian conditions.
Challenges Ahead
Despite the promise, Tajikistan faces several hurdles. Internet access reaches only 55% of rural communities, there is a shortage of trained remote sensing specialists, and the system’s annual maintenance is estimated at $50,000.
To address these challenges, ESCAP will provide training and technical support and integrate Tajikistan’s platform with global systems like Copernicus and UN-SPIDER.
Following implementation in Tajikistan, the system will be extended to Kazakhstan and Turkmenistan. In future phases, artificial intelligence tools will be introduced to boost forecast accuracy to 90%.
The long-term goal is the establishment of a unified regional water management system to help all Central Asian countries tackle mounting climate risks.
