Drought affects one quarter of Ukraine, largely in the southeastern regions of Zaporizhie, Kherson and Kharkiv, Tatiana Adamenko, head of the weather department of Ukraine’s Hydrometeorological Center, tells Interfax-Ukraine. The weather center will update its crop forecast in two weeks. The All-Ukrainian Agrarian Union says the drought could cause some harvests in southeast Ukraine to fall this year by as much as 50%.
