One of Europe's most valuable wetlands is shrinking — and satellite views suggest it could disappear completely within a single human lifetime.
Doñana National Park is a vast wetland system in southwestern Spain that supports one of the continent's richest ecosystems and plays a critical role in European and African bird migration and breeding. Using high-resolution data from the European Space Agency's (ESA) Sentinel-2 satellites, researchers found that the park's marshland is steadily losing surface water — a trend that, if left unchecked, could leave the marsh effectively dry in about 60 years, according to calculations from a recent water-resource monitoring study.
