A German parliamentary delegation canceled plans Monday for a visit to fruit farms in a drought-hit region of southern Spain, after a campaign in Germany to discourage consumers from buying “drought berries” sparked political controversy. The cross-party visit by nine German lawmakers this week was meant to include a stop in the Doñana national park in Andalusia, home to some of Europe’s most important wetlands. The conservative regional government of Andalusia, which is experiencing its worst drought in nearly three decades, wants to expand water extraction rights in the wetlands. Spain’s Socialist Prime Minister Pedro Sánchez has made the matter an issue in the campaign ahead of elections next month.
