Standing in his field of stunted, withered maize, Santi Caudevilla is very worried. “If the weather does not change it will be zero. Nothing is going to be harvested,” he said. Caudevilla, who grows maize, sorghum and other crops in Gimenells in Catalonia, has been hit hard by the severe drought which has hammered this part of northeastern Spain. Rainfall has been low for years. … It’s becoming increasingly hard to make ends meet as crops shrivel through lack of water – or cannot be planted at all. Droughts are a fact of life in this corner of Spain. “They are typical of Catalonia’s Mediterranean climate,” said Albert Ruhi, a freshwater ecologist at the University of California, Berkeley, who is originally from Catalonia.
