Venice recruits next generation in flooding fight
"As a result of subsidence in Venice and rising waters, the average sea level has risen by 30 centimetres (12 inches, or 1 foot) in the last 150 years and is expected to rise by another 50 centimetres by the end of the century," he told AFP.
"The MOSE was designed to close a maximum of 50 times a year," said Umgiesser. "If sea levels continue to rise at this rate, from 2100, it would need to be triggered 300 to 400 times a year."
Another solution would be to raise Venice above the waves by 30 to 50 cm by injecting sea water into the foundations of the city, but for now this idea remains entirely theoretical.
In the meantime, Jane da Mosto, head of environmental non-profit We Are Here Venice, is relying on salt marshes in the lagoon to slow the acqua alta and ease the currents.
Restoring these wetlands, decimated by climate change and urbanisation, could be a natural solution to Venice's problems, she argues.
