NPR's exclusive report examines the impact of Ukraine's conflict on its agriculture with insights from NASA Harvest.

The war in Ukraine has gouged a scar in the landscape so vast, that it's easily visible from space.

A new analysis by NASA's Harvest program and shared exclusively with NPR shows that between 5.2 and 6.9 million acres (2.1-2.8 million hectares) of prime farmland have been abandoned as a result of the war since 2021. The abandoned fields represent between 6.5 and 8.5% of Ukraine's total cropland.

The losses represent "a massive amount of land," said Inbal Becker-Reshef, the program director for NASA Harvest and a research professor at the University of Maryland and the University of Strasbourg in France. Much of the fallow land lies in a vast swath along the front line of the war, while other fields are in areas recently retaken by Ukrainian forces, she said.

The scar left by the fighting is easily visible in satellite imagery from the commercial company Planet. Paradoxically, the untended farmland is still green because it has filled with weeds and other plants. Harvested plots mostly appear brown in the autumn.
