Ukrainians begin the harvest in a missile crater-marked field near the city of Kramatorsk, in the conflict-stricken eastern Donbas region. The invading Russian forces now occupy about 22 percent of Ukraine's farmland, impacting one of the major suppliers to global grain and edible oils markets, NASA says. The war's disruption of harvesting and planting -- including farmers fleeing the war, the lack of labour and fields pockmarked by shelling -- could have a heavy impact on global food supplies, according to NASA scientists.
