Greece's vanishing lake Koroneia exposes rapid climate impact: report
Northern wetland shrinks to a fraction of its original size amid prolonged drought, rising temperatures, and heavy agricultural water extraction
Accelerated climate change and severe drought have severely depleted water levels across major global waterways in recent years, a vulnerability starkly underscored by Lake Koroneia in northern Greece.
According to a scientific report released this week, the once-vibrant northern wetland has lost more than 90% of its surface area, contracting into a shallow, mud-cracked basin under the compounding pressures of rising temperatures and intensive agricultural irrigation.
A once-thriving wetland is down to a fraction of its size, offering an urgent window into the accelerating climate crisis reshaping southern Europe.
Contracting from 34.4 square kilometers to just 2.7 square kilometers, Lake Koroneia in northern Greece was once a vital wetland into a shallow, mud-cracked basin.
Environmental authorities and researchers attribute the dramatic decline to a compounding crisis of persistent low rainfall, escalating regional temperatures, and extensive over-irrigation by local agriculture.
Before drought took hold, Koroneia Lake in northern Greece was a protected wetland, a refuge for thousands of migratory and water birds including flamingos, and a magnet for tourists as well as local fishermen and farmers.
Today, after a decade of low rainfall and over-irrigation, Koroneia, once the fifth largest lake in Greece, has shrunk to less than a tenth of its original size, according to data from the National Observatory of Athens.
The water that remains is collected in a series of murky ponds and the exposed lake bed is a vast mud plain cracked and bleached by years of baking sun.
Once a thriving habitat for flamingos, migratory birds, and local fisheries, the shrinking water body has underscored vulnerabilities across southern Europe's agricultural heartlands.
The European Union previously penalized Greece over inadequate protections against illegal groundwater drilling and industrial pollution surrounding the basin.
While national authorities have stepped up monitoring and restricted extraction under strict EU guidelines, climate scientists warn that accelerating desertification trends across the Mediterranean threaten similar ecosystems with permanent collapse.
