# Ukraine and Russia's grain harvest under threat amid Black sea attacks

> Black Sea attacks have trapped millions of tons of Ukrainian and Russian grain in storage as insurers withdraw from covering commercial ships. Farmers in Ukraine are scaling back corn and barley plantings and shifting toward oilseeds. A ceasefire or reopened route could release large stockpiles.
