Urbanisation | 21st Century Challenges What’s the challenge? Humans are rapidly becoming an urban species, with millions of people migrating to cities each year. Over half of the world’s population live in urban areas and this is likely to reach 70% of the population by 2050. How will urban centres across the world keep pace with predicted continuing growth? What are the visions of tomorrow’s cities? FactsIn 2008 for the first time in history more people lived in cities than in rural areas.Slums are the world’s fastest growing habitat. Rural to urban migration Much of global urbanisation is due to rural-urban migration. The global proportion of urban population rose dramatically during the twentieth century: 1900 13% (220 million) 1950 29% (732 million) 2005 49% (3.2 billion) By 2030 this figure is estimated by the United Nations to be 60% (4.9 billion) Source: The UN World Urbanization Prospects (2009) Cities Slums Slums can also be a source of inspiration and highlight the ingenuity and resourcefulness of populations.

The 100 million city: is 21st century urbanisation out of control? | Cities The 1960 street map of Lagos, Nigeria, shows a small western-style coastal city surrounded by a few semi-rural African villages. Paved roads quickly turn to dirt, and fields to forest. There are few buildings over six floors high and not many cars. No one foresaw what happened next. But new research suggests that the changes Lagos has seen in the last 60 years may be nothing to what might take place in the next 60. Hundreds of far smaller cities across Asia and Africa could also grow exponentially, say the Canadian demographers Daniel Hoornweg and Kevin Pope at the University of Ontario Institute of Technology. Under the researchers’ extreme scenario – where countries are unable to control fertility rates and urbanisation continues apace – within 35 years more than 100 cities will have populations larger than 5.5 million people. What happens to those cities over the next 30 years will determine the global environment and the quality of life of the world’s projected 11 billion people.

'Forest cities': the radical plan to save China from air pollution | Cities When Stefano Boeri imagines the future of urban China he sees green, and lots of it. Office blocks, homes and hotels decked from top to toe in a verdant blaze of shrubbery and plant life; a breath of fresh air for metropolises that are choking on a toxic diet of fumes and dust. Last week, the Italian architect, famed for his tree-clad Bosco Verticale (Vertical Forest) skyscraper complex in Milan, unveiled plans for a similar project in the eastern Chinese city of Nanjing. The Chinese equivalent – Boeri’s first in Asia – will be composed of two neighbouring towers coated with 23 species of tree and more than 2,500 cascading shrubs. But Boeri now has even bolder plans for China: to create entire “forest cities” in a country that has become synonymous with environmental degradation and smog. Boeri described his “vertical forest” concept as the architectural equivalent of a skin graft, a targeted intervention designed to bring new life to a small corner of China’s polluted urban sprawl.

Le port antique de Rome revit grâce au virtuel Des chercheurs ont déblayé virtuellement le plus grand port antique de Méditerranée, aujourd’hui complètement ensablé, et ont remis en mouvement l’eau qui s’y trouvait. Un travail qui a permis de répondre à une question qui taraudait les archéologues depuis longtemps. Le port antique de Rome, le Portus, fut le plus grand port du monde méditerranéen antique. Heureusement, grâce à la magie du virtuel, une équipe de géoarchéologues et d’océanographes a réussi (link is external) à déblayer l’immense bassin et à le rouvrir à la circulation de l’eau et des sédiments1 ! Grand comme… 275 terrains de foot ! Situé à 32 kilomètres à l’ouest de Rome, le Portus a été construit à partir de l’an 42 apr. Embouchure actuelle du Tibre. La structure globale du Portus est connue depuis plus de 400 ans déjà. Ce fameux bassin de Trajan, de forme hexagonale et d’une profondeur pouvant aller jusqu’à 7 mètres, permettait à l’époque d’accueillir plus d’une centaine de navires. Le numérique à la rescousse R.

Growing mega-cities will displace vast tracts of farmland by 2030, study says | Environment Our future crops will face threats not only from climate change, but also from the massive expansion of cities, a new study warns. By 2030, it’s estimated that urban areas will triple in size, expanding into cropland and undermining the productivity of agricultural systems that are already stressed by rising populations and climate change. Roughly 60% of the world’s cropland lies on the outskirts of cities—and that’s particularly worrying, the report authors say, because this peripheral habitat is, on average, also twice as productive as land elsewhere on the globe. “We would expect peri-urban land to be more fertile than average land, as mankind tends to settle where crops can be produced,” says Felix Creutzig from the Mercator Research Institute on Global Commons and Climate Change in Berlin, and principal author on the paper. This may not appear to be a huge figure at first glance, but on the regional scale the picture changes.
