The Belgian architecture firm vincent callebaut architectures is known for turning the urban in ecological, always with a view to help the planet. Its most recent project is Asian Cairns pointing to a rural exodus recurrent and uncontrolled urbanization, proposing farmscrapers (vertical farms located within cities) that produce more energy than they consume it through food production and better use of wind and solar energy.

At the end of 2011 in China, the number of inhabitants in cities exceeded the number of inhabitants in rural areas. While 30 years ago only one in five Chinese living in the city, city dwellers now represent 51.27% of the total population of 1347 million people. The urban population is expected to increase to 800 million in 2020 mainly spread in 221 cities of at least one million people (compared to only 40 in Europe on the same scale) and 23 megacities of more than five million people.

The challenge is to create a fertile development with zero carbon emissions and positive energy, this means producing more energy than it consumes, to reconcile economic development with protection of the planet.

Cities are currently responsible for 75% of global energy consumption and reject 80% of global CO2 emissions. By the repatriation of fields and ways of farming in the heart of the city through the creation of green spaces (farmscrapers within the city) and vertical wind implantation and solar power stations.

Sustainable development should therefore enable innovative solutions for a resilient economy to climate change that is in total harmony with the biosphere to preserve the ability of future generations to meet their needs.

It is designed in the form of three intertwined spirals representing the three elements: fire, earth and water. Each coil is wound around two towers and how urban ecosystems.
