Venice, known as the “Floating City” or “The City of Canals”, is an iconic Italian city located in the Veneto region.
This historic and vibrant city has been home to many civilizations for centuries and is a popular destination for tourists.
Unfortunately, due to its unique location in a lagoon on the Adriatic Sea, Venice has been facing an issue for years – it is sinking.
In this article, we will explore why Venice is sinking and what efforts are being made to address the problem.
What are the causes of Venice’s sinking?
There are multiple factors contributing to Venice’s sinking, primarily due to human activities. The most significant contributors are:
Climate change and sea level rise
Climate change has caused the sea level to rise significantly over the past several decades.
This increase has put immense pressure on Venice, causing the city’s foundations to sink further into the lagoon.
In addition, new construction projects have been built as well as increased tourism that has resulted in soil compaction and thus a decrease in surface elevation.
All of these things lead to the lagoon waters rising faster than before, thus further exacerbating the already sinking city.
Groundwater extraction
Groundwater extraction is another human activity that has been depleting Venice’s groundwater and causing it to sink even faster.
The land underneath Venice contains a large amount of water, which is extracted from wells and pumps in order to provide drinking water for the city’s inhabitants.
This extraction causes the ground to become less stable and further contributes to Venice’s sinking.
In addition, heavy rainfall can cause the underground aquifers to become even emptier, resulting in an even higher rate of subsidence.
Lack of maintenance and infrastructure problems
In addition to climate change and water extraction, Venice’s lack of proper maintenance has caused the city to sink even further.
Crumbling infrastructure such as bridges, foundations, and embankments are in desperate need of repairs that have been neglected for years.
This lack of care has contributed to Venice’s sinking, as the foundations and infrastructure are unable to withstand the pressure from water levels that are rising higher each year due to climate change.
Building on unstable soil
Venice’s unstable is another factor that has caused the city to sink further.
The on waters are very shallow and the soil of Venice is highly porous – both of these factors cause the land to be prone to quick subsidence when too much pressure is put on it.
As new buildings and infrastructure are built on this unstable soil, it can cause the ground to sink even faster.
Furthermore, the added weight of these structures also contributes to further subsidence as they put an extra burden on already weak foundations.
Human activity
Lastly, human activity has also greatly contributed to Venice’s sinking.
The construction of bridges and other structures has caused the land to sink faster due to their weight, while water extraction from the aquifers beneath the city has further weakened the foundations of Venice.
In addition, tourism and other human activities such as boat traffic can cause further erosion and weakening of the city.
All of these factors combined caused Venice to sink at an alarming rate.

What are the solutions to prevent further sinking?
There are a few measures that can be taken to help prevent Venice from sinking further. Some of these include:
Building dams/barriers
The most effective way to reduce the rate at which Venice is sinking is to build dams and other barriers around the city.
These structures will form a protective barrier, which can help minimize the effects of flooding, high tides, and erosion.
Dams can also be used to divert water away from Venice, as well as provide extra support for its foundations.
Constructing additional foundations
To help support the existing foundations of Venice, additional foundations can be constructed. This would involve building extensions beneath the city’s buildings and infrastructure in order to provide extra support against subsidence. Additionally, this could also create more space for groundwater to be stored, which could reduce groundwater extraction.
Restricting tourist activity
Another solution to help prevent Venice from sinking further is to restrict the number of tourists who are allowed into the city.
Large numbers of visitors can put a strain on Venice’s infrastructure and cause additional erosion or wear and tear.
Limiting the number of tourists, could reduce their impact on the city and help prevent further subsidence.
More sustainable building practices
More sustainable building practices should be adopted in order to reduce the city’s sinking.
This involves using materials that are better suited for Venice’s marshy soils, as well as implementing green technologies and renewable energy sources whenever possible.
Additionally, rainwater harvesting systems can also be implemented to help reduce the city’s dependence on groundwater.
Prohibiting cruise ships from entering the city
Finally, cruise ships should be prohibited from entering the city in order to prevent further erosion and subsidence.
The large size of these vessels can cause significant damage to Venice’s foundations, so it is important to ensure that they remain out of the city.
This could be done by introducing regulation in the form of docking fees or other restrictions.
Final thoughts
Venice has been sinking for centuries due to various factors such as its unstable soil, human activity and rising sea levels.
The rate of this subsidence has increased significantly in recently, leading to fears that Venice could soon be lost forever if measures aren’t taken to protect it.
However, there are a few solutions that can help slow down or even reverse the process of Venice’s sinking.
These include building protective dams, constructing additional foundations and restricting tourism numbers.
Additionally, more sustainable building practices should be adopted as well as prohibiting cruise ships from entering the city.
If these solutions are implemented soon, then it is possible that Venice can be saved from its current downward trajectory and preserved for future generations.
