The Future of Sinking Cities: Lessons from Alexandria
The Immediate Impact of Rising Sea Levels
On a sunny January morning in El Max, a small fishing community west of Alexandria, Ahmed Gaz, a lifelong fisherman, is untangling his net after a dawn catch. Gaz, like many in the neighborhood, has spent his entire life by the sea. "My whole life is in the sea. My life, my work and my livelihood," he says. However, the sea that sustains him is also threatening his existence.
Alexandria, Egypt’s second-largest city, is one of the world’s sinking cities, along with Venice, Miami, Lagos, and Jakarta. An IPCC report warns that if global sea levels continue to rise at the current rate, thousands of kilometers of the Nile delta could be fully submerged by 2100. This is a grim reality for residents like Gaz, who are witnessing the effects of the climate crisis firsthand.
Environmental Risks Beyond Rising Sea Levels
El Max, like the rest of Egypt’s Mediterranean coast around the delta, faces several other environmental risks. These include land subsidence, soil erosion, earthquakes, and water pollution from nearby petrochemical plants. These factors add to the increasing vulnerability of the area, making it a hotspot for environmental degradation.
The Human Factor: Resistance to Change
The people of El Max will eventually have to move to survive, but a study by the Mixed Migration Centre found that 90% of the residents have no plans to leave. Only a handful believe that the rising water is even a threat. "I trust my eyes, not the weather forecast," Gaz says, echoing a common sentiment among the community.
Mohamed Abdrabo, director of Alexandria University’s Research Centre for Adaptation to Climate Change, explains part of the problem: "People are not interested in the far future" due to the current economic situation. The community’s lack of awareness about the long-term impacts of climate change is a significant barrier to adaptation.
Historical Context: Alexandria’s Tsunamis and Earthquakes
Alexandria has a rich history marked by natural disasters. The city, founded in 331 BC by Alexander the Great, has experienced several tsunamis and earthquakes. One of the most devastating tsunamis occurred in 365 AD, caused by an 8.5-magnitude earthquake in Crete. This event had disastrous effects across the eastern Mediterranean, causing water to go inside the soil and destroying the entire ancient port. Some archaeologists believe that the temples of Alexander the Great and Cleopatra are still underwater.
Modern Challenges: Coastal Development and Preparedness
In its present cycle, Alexandria faces a different dynamic. Rapid coastal development, including the loss of more than 40% of its beaches in the past 25 years, has raised concerns among residents. Despite being recognized by UNESCO as Egypt and Africa’s first "tsunami-ready" community, local researchers feel that the city is not prepared for the increasing risks.
Hussein, a local researcher, questions the effectiveness of the concrete blocks installed along Alexandria’s corniche to protect the shore. Several experts argue that this is an unviable solution in the long term because water goes under the blocks and into the soil.
The Emotional Toll: Attachment to Land and Sea
For many in El Max, the idea of leaving their homes is unthinkable. "I’m like a fish. If they remove me from the sea, I’ll die," says As Elsayed Ibrahim, a local fisherman. Umm Amr, who runs a kiosk on El Fanar beach, echoes this sentiment: "They want us to leave here, but I don’t know where to go. This sea is my soul, and I cannot live without it."
The Need for Adaptation and Collaboration
Despite the increasing risks, many residents prefer to stay and find ways to adapt. Hussein suggests that people in sinking cities around the world could collaborate and share strategies for saving their home towns. "All we’re asking for is that we’re given the tools to learn how to adapt," she says.
In response to these challenges, Egypt’s Ministry of Water Resources and Irrigation has stated that they are implementing coastal-protection projects to counter the negative effects of climate change and provide protection for citizens and facilities.
Future Trends and Predictions
| Environmental Risk | Current Impact | Future Predictions |
|---|---|---|
| Rising Sea Levels | Submergence of coastal areas | Thousands of kilometers of the Nile delta could be fully submerged by 2100. |
| Land Subsidence | Increased vulnerability | Continued land sinking and increased flooding. |
| Soil Erosion | Coastal erosion and loss of beaches | Accelerated erosion and loss of coastal land. |
| Earthquakes and Tsunamis | Historical and recent disasters | Increased frequency and intensity of earthquakes and tsunamis. |
| Water Pollution | Health and environmental hazards | Continued pollution and health risks. |
FAQs
Q: What are the main environmental risks facing Alexandria?
A: The main environmental risks include rising sea levels, land subsidence, soil erosion, earthquakes, tsunamis, and water pollution from petrochemical plants.
Q: How are residents of El Max adapting to these risks?
A: Many residents are resistant to leaving their homes and are looking for ways to adapt to the changing environment. Some have been moved to high-rise buildings farther inland, but many prefer to stay close to the sea.
Q: What measures is the Egyptian government taking to protect Alexandria?
A: The Egyptian government is implementing coastal-protection projects to counter the negative effects of climate change and provide protection for citizens and facilities.
Q: What can other sinking cities learn from Alexandria?
A: Other sinking cities can learn about the importance of community engagement, preparedness, and the need for long-term adaptation strategies. Collaboration and sharing of best practices can help save home towns.
Did You Know?
Alexandria was recognized by UNESCO as Egypt and Africa’s first "tsunami-ready" community, but local researchers feel that the city is not prepared for the increasing risks.
Pro Tip:
For residents of sinking cities, staying informed about climate change and its long-term impacts is crucial. Engaging with local authorities and participating in community adaptation efforts can make a significant difference.
