Today, 56% of the world's population live in cities, and the proportion will increase in the coming years. Rapid urbanization leads to the overpopulation of cities, lack of land for the construction of new residential buildings. One of the problem's solutions – a floating city. Today this initiative has been discussed during the round table, which was held at the UN-headquarters in New York.
Almost all of the world's population growth in the future will be due to an increase in the number of urban residents. By 2030, city dwellers will account for 60 percent of the world's population, and in 2050 - approximately 68 percent.
Deficiencies in urban planning, coupled with increased production and consumption, often lead to urban pollution and environmental degradation. The pace of new housing construction has lagged far behind the growth of the urban population. The problem can be solved with the help of "floating cities". These initiatives are already being implemented.
As noted by the first Deputy Secretary-General of the UN, who spoke at the meeting, the urban poor in Lagos already live in floating villages on the outskirts of the city due to the lack of land. And in Singapore, the land is so small that the city authorities resorted to land reclamation and, thus, compared with 1965, when the country gained independence, increased the size of the country by almost a quarter.
"It is not every day that I speak on such an unusual and innovative topic as floating cities" - said first Deputy Secretary-General, Amina Mohammed. She called the new initiative a potential solution for building a more sustainable future. The representative of the UN added, that modern cities and their inhabitants face different threats related to climate change.
According to the UN, almost 60 percent of cities with a population of more than 300 thousand people are at high risk of cyclones, droughts, floods, earthquakes and volcanic eruptions.
"Today we can no longer continue to build cities like New York or Nairobi," - said Amina Mohamed. She called for the construction of cities for people, not cars, to build cities that will not be under water as a result of rising sea levels – in short, the city should stand on the water, not under it.
Amina Mohammed noted that in the construction of floating cities, it is also possible to experiment with the cultivation of agricultural products with the help of hydroponics, as well as by expanding the aquaculture sector. A floating dairy farm is already under construction in Rotterdam.
"Floating cities can be a step towards the sustainable development..." - said the Deputy Secretary-General.
