Ukraine’s unexploded ordnance threat mapped by satellites

NASA's satellite data helps identify unexploded ordnance in Ukraine

NASA Harvest researchers have developed a new method using satellite technology to detect artillery craters in Ukraine, a vital tool for locating unexploded ordnance (UXO). UXO remains a significant threat in conflict zones and can last for decades.

With up to a third of Ukraine contaminated by UXO, detecting and removing these dangers is crucial.

The ongoing war between Russia and Ukraine has disrupted agricultural production, which is essential to Ukraine’s economy. Agriculture accounts for 10% of the country’s GDP, over 20% of its exports, and provides 5% of employment.

Ukraine is a major producer of crops like wheat, maize, and sunflower oil. Monitoring these crops is vital for global food security, especially as the war continues to affect farmland.

In May 2024, NASA Harvest introduced a new satellite-based method to map sunflower cropland in Ukraine. Using radar satellites, the team produced high-resolution maps that provide detailed insights into sunflower production, particularly in conflict-impacted regions.

The findings show a 5% decrease in sunflower-planted areas in 2022 compared to 2021, with most losses in Russian-occupied regions, where sunflower farming dropped by 29%.

NASA Harvest’s work highlights the value of satellite technology in conflict zones. It not only helps identify UXO but also ensures that agricultural monitoring continues, even in dangerous areas.

By providing crucial data on crop health and yield estimates, these efforts support food security and safety for Ukrainian farmers.
