From Amsterdam to Venice to Miami: 10 cities at risk of disappearing by 2050

More than 570 coastal cities and 800 million people are at risk from rising sea levels and land subsidence, according to a report titled "The Future We Don't Want" by the international network of C40 cities, which says these cities will be exposed to rising sea levels and increasingly frequent flooding.

The situation will worsen if urgent measures are not taken at a global level, not only regarding warming, but also situations such as land subsidence, erosion or sediment loss.

Here are the 10 cities at risk by 2050:

New Orleans (USA)

Much of the city, the birthplace of jazz, is now below sea level and protected by a complex system of dams and hydraulic pumps. After Hurricane Katrina in 2005, billions were invested in improving the defenses, but the land continues to sink and the wetlands that served as a natural barrier are dwindling. Experts believe that saving it will require ever greater expenses.

Miami (USA)

Neither river deltas nor lake basins, but highly porous limestone rocks. Florida's most famous city is located on this terrain, allowing seawater to penetrate underground, bypassing dams and barriers. Added to this is the rising sea level, which causes flooding during high tides. Because of these features, experts consider Miami one of the most challenging climate adaptation scenarios.

Mexico City

Built on the basin of the ancient Lake Texcoco, the Mexican capital is not afraid of the sea, but of the land it sits on. Massive groundwater extraction is causing one of the fastest rates of subsidence on the planet, with the land sinking by about 20-30 cm per year. This causes ongoing damage to roads and infrastructure, making life difficult for a megalopolis of 21 million inhabitants.

Alexandria (Egypt)

Founded by Alexander the Great in 331 BC, Alexandria is one of the oldest cities in the Mediterranean. Today, it is threatened by coastal erosion and global warming, which are causing saltwater intrusion into the Nile Delta. According to some studies, it will have to adapt to repeated floods, which will cause significant damage not only to agriculture, but also to its precious archaeological heritage.

Bangkok (Thailand)

Located in the Chao Phraya River Delta, it is built on soft, unstable ground. Many areas of the city are about two meters below sea level, and studies predict increasing coastal flooding over the coming decades. More intense monsoon rains and climate change threaten to devastate a metropolis of more than 10 million people.

Jakarta (Indonesia)

Founded in the 5th century on the delta of 13 rivers, it has sunk more than four meters in recent years and today about 40% of the urban area is already below sea level. This combination of subsidence and rising sea levels has prompted the local government to invest $32 billion to build a new capital, Nusantara, from scratch in the Borneo jungle, where all activities will gradually relocate.

Manila (Philippines)

The capital of one of the world's most typhoon- and flood-prone countries, Manila is also facing the twin problems of subsidence, caused by overexploitation of groundwater and rising sea levels. Some areas of the metropolis are sinking by about two centimeters a year and, without radical intervention, could be underwater by the end of the century.

Ho Chi Minh City (Vietnam)

The economic heartland of Vietnam, it lies in an extremely flood-prone region, with approximately 40-45% of the urban area lying less than one meter above sea level. In addition to rising sea levels, the city faces subsidence caused by groundwater extraction, a combined effect that increases the risk of chronic flooding in many neighborhoods.

Venice (Italy)

It is perhaps the most famous city in the world when it comes to climate risk. The Laguna Serenissima is located just above sea level, and the city continues to slowly sink as sea levels rise. The MOSE mobile dam system has reduced the risk of extreme flooding, but scientists believe that further adaptation measures will be needed in the long term.

Amsterdam (Netherlands)

Built among canals, polders and lowlands, Amsterdam is protected by dikes, pumps and barriers that make the Netherlands a global model for water protection. However, the risk remains real: according to the Dutch Delta Program, sea levels along the country's coastline could rise by more than a meter by 2100, forcing the Dutch to rethink their defenses to survive.
