On September 17, the Mongolian Drought Remote Sensing Monitoring System, known as DroughtWatch-Mongolia, was officially handed over to the Mongolian National Remote Sensing Center. This milestone took place during a regional seminar in Ulaanbaatar, where Wu Bingfang from the Aerospace Information Research Institute of the Chinese Academy of Sciences and Gomboluudev Purevjav, Director of the Mongolian Institute of Meteorology, Hydrology, and Environment, signed the transfer agreement on behalf of their respective institutions.
The system was developed under the coordination of the UN-ESCAP Regional Drought Mechanism, with support from the Chinese Academy of Sciences' Center for Space Disaster Reduction and the Asian Space Disaster Reduction Scientific Cooperation Research Project. The team conducted in-depth cooperation, focusing on the adaptability of drought remote sensing indices. They introduced a multi-index, comprehensive monitoring model tailored specifically for Mongolia's continental climate, overcoming previous limitations of single-index systems that failed to accurately reflect drought conditions.
Since 2014, Wu Bingfang’s team has collaborated with Mongolia on multiple field observation campaigns. After four years of validation, the system met operational standards and successfully adapted drought monitoring techniques to local conditions. The team also focused on localization, offering continuous technical support, training, and capacity-building initiatives to the Mongolian National Remote Sensing Center. As a result, the center now independently conducts drought monitoring and analysis, publishing the Mongolian National Drought Monitoring Report to provide real-time updates for disaster management agencies.
This initiative has significantly enhanced Mongolia’s ability to respond to droughts, supporting key ministries such as the Ministry of Light Industry and the Ministry of Nature, Environment, and Tourism. The system has become a crucial tool in improving the country’s overall drought mitigation strategies.
DroughtWatch, the global drought monitoring system developed by the Aerospace Information Research Institute, has been in operation for over two decades. Through continuous improvements and upgrades, it has evolved into a multi-satellite, multi-scale monitoring system. Its successful implementation in Mongolia, along with collaborations in Cambodia and Sri Lanka, led to the creation of a standardized operation manual for drought monitoring in the Asia-Pacific region. Today, DroughtWatch serves as a core system for the UN-ESCAP Asia-Pacific Drought Mechanism, demonstrating its value as a reliable and scalable solution for drought early warning and response.
