In the face of increasingly severe climate change, rising sea levels and extreme weather events threaten human life directly. The idea of a floating city has emerged as a bold and promising solution. It is not only a modern engineering project but also a symbol of humanity’s adaptability and creativity in confronting global challenges.
Floating cities are designed with flexible modular structures that can be connected or detached depending on needs. Residential areas, parks, schools, and hospitals are all built on the water, creating a new living space. Renewable energy from the sun, wind, and even ocean waves provides electricity for the entire system, helping to reduce greenhouse gas emissions. In addition, floating cities integrate green spaces and aquaculture, forming a sustainable ecosystem that both supports daily life and protects the environment.
The significance of floating cities goes beyond technical aspects. They open up a new perspective on human living spaces. If in the past, land was the only foundation for urban development, now water surfaces can also serve as a platform for growth. Floating cities thus become symbolic of innovation and resilience. At the same time, they contribute to climate justice by offering vulnerable communities—especially those in coastal and delta regions—a safer place to live.
In Vietnam, where the Mekong Delta is heavily affected by rising sea levels and saltwater intrusion, the floating city model could become a strategic solution. With appropriate policies and community participation, floating cities would not only provide safe shelter but also drive socio-economic development in the 21st century.
In short, floating cities represent humanity’s aspiration to overcome nature’s challenges and safeguard life. They open the door to a future where urban areas are no longer limited to land but can expand across the seas—both combating climate change and building a new civilization upon the water.
