Amsterdam, New Orleans, and Jakarta Face Growing Risks from Rising Seas and Turn to Engineering to Avoid Tragedies
Three cities below sea level are on high alert due to rising water levels and the frequency of extreme weather events. They are urban areas that challenge geography and rely on technological solutions and rigorous planning to keep millions of people safe.
According to data from the IPCC (Intergovernmental Panel on Climate Change), cities like Amsterdam, New Orleans, and Jakarta are among the most vulnerable in the world. They employ dikes, pumps, and seawalls to contain the water, but face technical limits in the face of rising seas.
Amsterdam: The City That Lives with Its Feet in Water
Located up to 6 meters below sea level, Amsterdam has been on high alert since the Middle Ages. To protect its 900,000 inhabitants, the Netherlands created the most complex dike system on the planet. The Delta Works project includes movable barriers that close entire channels during storms.

Even with the advanced system, the Dutch government is already discussing relocating populations in case of extreme events. The KNMI, the official meteorological service, predicts that sea level in the region could rise by up to 1.2 meters by the end of the century.
New Orleans: Recent Tragedy Shapes Constant Vigilance
New Orleans has also been on high alert since Hurricane Katrina devastated the city in 2005. More than 1,800 people died after the dikes protecting the city failed. Located between the Mississippi River and Lake Pontchartrain, part of the city is even 2.5 meters below sea level.
Since then, the United States has invested over US$ 14 billion in reinforcing containment systems. The city now has automated pumps and hydraulic walls, but experts warn that ground subsidence increases the risk each year.
Jakarta: City Sinks While the Sea Rises
With approximately 10 million inhabitants, Jakarta is on high alert because it faces two problems at once: the sea is rising and the ground is sinking. Studies by the Indonesian government indicate that parts of the city sink up to 25 cm per year due to excessive groundwater extraction.
The “Great Maritime Dike” project, a massive coastal barrier, is under construction to contain the sea. But experts such as those from Deltares, a Dutch consultancy that assists with the plan, warn that the project needs to be completed by 2030 to avoid irreversible losses.
In your opinion, is Brazil prepared to face similar scenarios in coastal cities like Santos and Recife?
