Venice has battled rising water levels since the fifth century. But today, the water seems to be winning. Several factors, both natural and man-made, cause Venice to flood about 100 times a year — usually from October until late winter — a phenomenon called the acqua alta.

When did Venice start sinking?
During the 20th century, when many artesian wells were sunk into the periphery of the lagoon to draw water for local industry, Venice began to subside. It was realized that extraction of water from the aquifer was the cause. The sinking has slowed markedly since artesian wells were banned in the 1960s.
Which cities will be underwater in 2050?
Jakarta, Indonesia. The capital of Indonesia is the fastest sinking city in the world—it’s sinking at the rate of 6.7 inches per year.

Is Venice still sinking?
It has been sinking for many centuries and will continue descending into the lagoon over the next millennia. In addition to the historical causes due to the lack of effective land support systems (technically, ‘subsidence’), is the increase in water levels as a result of man-made climate change.
