There has been concern about how the large-scale Russian invasion would affect agriculture in Ukraine, which has among the most fertile fields on the planet.
"Now we are starting to get answers.
Our satellite-based production numbers for the 2022 winter wheat harvest in Ukraine clearly show that farmers had a largely successful harvest,” said Inbal Becker-Reshef, head of NASA's Harvest Program, in a statement.
Satellite images
With the help of satellite images, the researchers have analyzed the harvest in Ukraine during the year, and calculated it at 26.6 tons of wheat.
This is less than the 33 tonnes harvested the year before, but close to the average for the past five years of 27.9 tonnes.
But 22 percent of the harvest was on Russian-occupied land in the east, which means that Nasa estimates that Ukraine lost 5.8 tons of wheat, worth 1 billion dollars (10 billion kroner).
"Reduced uncertainty"
When the large-scale invasion began in February, some observers believed that as much as 30 percent of Ukraine's autumn crops would be wasted.
It wasn't that bad.
About 6 percent of the crops were never harvested and thus went to waste.
According to Nasa, it was mainly near the front line.
"Knowing the actual level of production in Ukraine contributes to reduced uncertainty and price volatility in food markets," says Becker-Reshef.
