War, rain and economic hardship have depressed Ukraine's wheat plantings, depriving the nation of vital export earnings in 2023 and heralding another year of tight global supplies and potentially high prices for basic foodstuffs.

Ukraine is one of the world's top wheat exporters, with key buyers including Egypt, Tunisia, Morocco, Indonesia, Pakistan and Bangladesh, and a further drop in production will leave many scrambling to find alternative supplies.

The race to secure grain is likely to drive up global prices, even hitting importers who don't buy directly from Ukraine.
