The true cost of growing food in Spain’s arid south

Las Tablas de Daimiel is a unique wetland in the vast, almost treeless plains of Castilla-La Mancha in central Spain, but the park has had the life sucked out of it to slake intensive agriculture’s insatiable thirst.

3,000 hectares (7,400 acres) of Las Tablas wetland are all that remain of what, according to the World Wildlife Fund, was once a system of 50,000 hectares.

The park has been dry for three years and where there were once aquatic species such as ducks, herons, egrets and freshwater crayfish, as well as tree frogs and the European polecat, now the wildlife has mostly vanished.

Climate change has resulted in Spain’s periods of drought getting longer. The Guadiana river is drying up, while agriculture has depleted the aquifer and polluted the groundwater with phosphates and other chemical fertilisers. In 2009, the wetland was so dry that subterranean peat fires broke out.
