Scientists have compiled a list of cities most endangered in the next century under the influence of climate change, natural disasters, population displacement and a number of other reasons. According to their forecasts, the risk group includes seven cities, including both megalopolises and small cities around the world.
1. San Francisco, USA. The reason is an earthquake
According to researchers at the University of California, by 2086, an earthquake of magnitude 7 or greater will occur in the San Francisco area. San Francisco is also one of the fastest-changing cities in the United States.
All of this is part of the movement of populations from expensive and geographically hazardous coastal areas inland. This trend could be accelerated by a devastating disaster.
2. Detroit, USA. The reason is population outflow
Since 1950, Detroit's population has declined by a third to about 950,000. It is assumed that the city's population will decline slowly but steadily, at least until 2030, the city's unemployment rate will be more than 10%. If these trends continue, then Detroit will change beyond recognition by 2100.
3. Venice, Italy. The reason is lowering the soil level
The capital of all lovers, the most romantic city in the world - Venice, has been sinking for about a millennium, but in the last century the rate of sinking has noticeably increased. Over the past 100 years, Venice has dropped by 24 centimeters. The government has plans to protect the city, aimed at raising it to sea level. However, whether they will work or not, no one knows.
4. Mexico City, Mexico. The reason is the lack of drinking water and subsidence of the soil
The capital of Mexico is at risk of being submerged. Mexico City stands on an aquifer that is also the main source of drinking water. Every time one of the city's 20 million inhabitants drinks water, the city sinks slightly.
According to some estimates, over the past 100 years, parts of the city have sunk 9 meters. Potentially worse. It is assumed that the aquifer is depleting. Although Mexico City is now growing rapidly, dwindling water supplies, and sinking soil, this could quickly reverse the trend.
5. Naples, Italy. The reason is a volcanic eruption
The volcano Vesuvius, which destroyed Pompeii in 79 BC, erupts about once every 100 years. The last time the eruption was recorded in 1944. Vesuvius is located in the Gulf of Naples in southern Italy, home to over 4 million people.
A possible eruption of the Vesuvius volcano can take the lives of not only the Neapolitans, but also more than half a million people living in the so-called "red zone" - the territory immediately adjacent to the volcano.
6. Timbuktu, Mali. The reason is desertification
Desertification, with sand dunes stepping on fertile land, is a problem for a number of countries in the south of the Sahara. The greatest threat threatens the city of Timbuktu in Mali, a city over 1000 years old that was an important center of Islamic education in the 15th and 16th centuries. A number of landscaping projects are under way in Mali. However, some parts of the city are already half covered with sand.
7. Ivanovo, Russia. The reason is population outflow
The list is completed by Ivanovo, a small town in the central part of Russia. The city's population is now about 448,000, but this figure is constantly decreasing.The ratio of men and women is in favor of the latter, the birth rate is falling, and the death rate is growing. Since there is practically no modern industry left in Ivanovo, educated young people are moving from the city to the promising Russian capital.
