In the past 20 years, nearly 300 buildings have collapsed in Alexandria. One significant factor contributing to this situation is climate change, particularly the rising sea levels in the Mediterranean.

Alexandria

In Alexandria, Egypt, a series of building collapses has highlighted the growing risks posed by climate change and rising sea levels. Over the past two decades, 280 buildings have collapsed, resulting in 85 fatalities, with 24,000 more buildings identified as being at risk. The main contributing factors are ageing structures, long-term neglect, and the infiltration of salt water into building foundations due to rising sea levels.

To address these challenges, local authorities have announced plans to construct 60,000 new homes and are implementing coastal protection measures, such as concrete barriers, to slow erosion. Despite these efforts, experts warn that these actions may only mitigate, not resolve, the underlying issues. The United Nations has warned that a significant portion of the city could become uninhabitable if current trends continue.

Alexandria threatened by climate change and rising sea levels

In this old quarter of Alexandria, workers are still clearing debris two weeks after the collapse of a building. This resident, who lives in a nearby apartment, is still in shock. It was around five in the morning. I'd just fallen asleep when ten minutes later I heard screaming and felt the ground shake. There was this huge cloud of dust, you couldn't see anything. Two people died, God rest their souls. Over the past two decades, 280 buildings have collapsed in Alexandria, killing 85 people. Across the city, ruins have become part of the landscape. Tarek Abdel Mahassam is an engineer. These buildings are all over 100 years old. Here, they're either abandoned in ruins or marked for demolition, but of course people are still living in some of them. 24,000 buildings are at risk of collapse in the next few years, according to government figures. The main reasons are ageing buildings, decades of neglect and the effects of climate change. Alexandria's biggest problem is that it's a coastal city that's been highly exposed to rising sea levels for years. That's led to more and more salt water seeping into the ground, weakening the foundations of the buildings and making them unstable. To help residents living in these unsafe buildings, the authorities have announced a plan to build 60,000 new houses. They're also trying to slow coastal erosion by building kilometres of concrete barriers between the beach and the city. These blocks are designed to protect the coastline. You'll find them at various points along Alexandria's beaches where the sea is eating away at the sand. I don't think this will solve the underlying problem, but it's a protective measure to try to reduce the impact and slow down the erosion. According to the United Nations, a third of the city could be underwater or uninhabitable by 2015.
