Self Sufficient Megacities

The world’s cities face many challenges. While it is expected that nearly 60 percent of the world population will be urban in the next two decades, the lack of harmony between space costs, social and environmental impacts of a city and its population is growing at an astonishing rate. The problems are most acute in the rapidly growing cities in developing countries. By one estimate, these cities are adding about five million people each month and generate new forms of existential problems. These include the problem of space, health, employment and the conflict with nature amid threats of climate change and global warming. This in no way can qualify for a sustainable future.

In addition, cities in developed countries are not immune to these challenges.However, as a United Nations report entitled State of the World’s Cities 2008-09 noted, cities also provide an opportunity “real to mitigate and reverse the effects of these challenges. This can be done through planning appropriate and more with the development of self-sufficient megacities, as you can read below.

Designed by the SBA design, Future Low Carbon City in Hainan Province of China is one among the many initiatives taken in the framework of Chinese Climate Protection, which aims to increase energy efficiency and protecting halfenvironment by reducing emissions and using renewable energy. Be developed in the area of ​​176.2 Yinggehai in southwestern Hainan.

Besides the green features, the architects have incorporated the ideas of a good balance between life and ecotourism. Unlike cities in the world today, it would be rural and urban areas and interaction is essential for all residents to contribute their part for sustainable development of the city. The City essentially depend on future renewable energy sources like solar and wind power and personal use Rapid Transit (PRT) of the transport system.

Green Tech City in Hanoi, capital of Vietnam, is home to about 20,000 people. It was designed by renowned Skidmore, Owings & Merrill (SOM). The USP of the new city is to harness the natural environment for the creation of urban microclimates comfortable for people.

Although it would ensure the continuity of local traditions of this city, which witnessed the rise and fall of many dynasties over 1,000 years of history, would take place several green initiatives for a sustainable future. The city relies on renewable energy sources for electricity and a robust system for flood management, harvesting rainwater and recycling waste.

Dalian is another mega Aeropolis that develop self-sufficient city in China. There will be an area of ​​the new airport in the northern city of Dalian. The city is divided into an area of ​​approximately 168 and is home to one million people in the end. It is also estimated that the area of ​​the new airport will handle around 25 million passengers a year. It was designed by a French company of Architecture, Design Associates NES.

Among the many green credentials of this megacities of the future, Aeropolis boast of several artificial lakes to ensure the availability of water and a green sanctuary.The city also have programs for the development of local communities.

The Inspiration 

The perception of an adverse outcome remains the greatest source of inspiration to all new developments. The same is true for mega autonomous cities. As the main purpose of all cities is to provide a comfortable stay to all its residents, the perception that current models can cause a major crisis in the future has enabled many governments, politicians and architects to think for themselves enough cities .


Autonomous megacities that boast several green credentials, as you read above. Some of them are:

1. The use of renewable energy sources.

2. Less traffic congestion and pollution through the use of personal rapid transit systems.

3. Robust systems for flood management, harvesting rainwater and recycling waste.

4. Increase in total forest cover, with many green areas.

The hurdles:

However, there are many obstacles to the development of self-sufficient megacities. The largest is at least the enthusiasm among planners and government. As they are also attacked in politics and current issues, barely paying attention to the future. However, there are also some other practical obstacles. Such as:

1. The availability of large amounts of land for new towns.

2. The availability of funds.

3. The problems of the current population of the cities.

Furthermore, most of the world’s population are poor. And might not be able to pay the expensive lifestyles of the new smart cities, unless supported by the government.

Is it feasible? 

Yes, however the self-sufficient megacities does not need to be developed in the cost of new cities. The government must develop alternatives while increasing the “green” credentials of the current urban housing.
