Urban population boom poses massive challenges for Africa and Asia | Global development Two-thirds of the world's population will live in cities by 2050, posing unique infrastructural challenges for African and Asian countries, where 90% of the growth is predicted to take place. The planet's urban population – which overtook the number of rural residents in 2010 – is likely to rise by about 2.5 billion to more than 6 billion people in less than 40 years, according to a UN report. Africa and Asia "will face numerous challenges in meeting the needs of their growing urban populations, including for housing, infrastructure, transportation, energy and employment, as well as for basic services such as education and healthcare", it adds. Future development targets should focus on creating inclusive cities with adequate infrastructure and services for all residents, said John Wilmoth, director of the UN's population division. The report says rapid urbanisation will bring opportunities for governments to improve access to important services.
The Urban Flâneur Guidebook: The technique of being a Suburban Flâneur (revised 15 September 2012) (This image was found within an interesting piece, "Unit 1: A Crisis of Place and the Alternative of the New Urbanism" , on New Urbanism Online.) One of the defining aspects of an urban flâneur is the activity of strolling down streets, stopping in cafes, observing people and thoughtfully contemplating the totality of the present urban environment that sh(e is immersed. This is usually accompanied by note writing and perhaps photographs. To an urban flâneur, the urban environment is multi-layered and not just a collection of houses, shops, streets, or factories, but a dynamic entity in which people conduct their lives and experience the world outside of them. In our present age, suburbs are now a significant part of all major cities in the world, developed and developing. As previously mentioned, one of the major distinctions of being an urban flâneur is the aspect of strolling or walking aimlessly.
Urban World: A new app for exploring an unprecedented wave of urbanization The McKinsey Global Institute’s updated Urban World app offers a look at how demographic shifts will affect the growth of cities through 2025. For more than a decade, the McKinsey Global Institute (MGI) has been studying the unprecedented global wave of urbanization. As the business and economics research arm of McKinsey, we provide leaders in the commercial, public, and social sectors with the facts and insights on which to base management and policy decisions. For years, demographic trends worked in favor of urban growth—huge cohorts of working-age people fueled cities’ economies. But now there is a radical break in that trend. Two major shifts are happening at the same time: population growth is slowing worldwide, and rural-to-urban migration is waning as a force for urban expansion, particularly in developed economies.

Urbanization An urbanizing world Today, population growth largely means urban population growth. UN projections show the world’s rural population has already stopped growing, but the world can expect to add close to 1.5 billion urbanites in the next 15 years, and 3 billion by 2050. How the world meets the challenge of sustainable development will be intimately tied to this process. A world of opportunity For many people, cities represent a world of new opportunities, including jobs. The opportunities there extend beyond just jobs. The urbanization process – which is particularly pronounced in Africa and Asia, where much of the world’s population growth is taking place – is also an enormous opportunity for sustainability, if the right policies are put in place. Inequality and vulnerability Still, the face of inequality is increasingly an urban one. Urban land is expanding much faster than urban population, a phenomenon known as urban sprawl. UNFPA at work

Today, the urban represents an increasingly worldwide condition in which political-economic relations are enmeshed.

Garden Bridge: Tough questions for £175m Thames project Image copyright Heatherwick Studio The proposed Garden Bridge across the River Thames has run into trouble after changes in the government and the end of Boris Johnson's run as London mayor. New Transport Secretary Chris Grayling is due to decide whether to extend a £15m government underwriting of the £175m project until September 2017. But tough questions are being asked in Whitehall about the footbridge and its public value, Newsnight understands. The Garden Bridge Trust said it hoped ministers would continue to support it. The 366m (1,200ft) tree-covered Garden Bridge, whose construction is yet to begin, would span the Thames between Temple and the South Bank. Mr Grayling is understood to be keen to study all the options ahead of his decision, which needs to be made imminently to allow the trust - the charity responsible for building the bridge - to file its accounts this week.

World’s population increasingly urban with more than half living in urban areas | UN DESA | United Nations Department of Economic and Social Affairs Today, 54 per cent of the world’s population lives in urban areas, a proportion that is expected to increase to 66 per cent by 2050. Projections show that urbanization combined with the overall growth of the world’s population could add another 2.5 billion people to urban populations by 2050, with close to 90 percent of the increase concentrated in Asia and Africa, according to a new United Nations report launched today. The 2014 revision of the World Urbanization Prospects by UN DESA’s Population Division notes that the largest urban growth will take place in India, China and Nigeria. These three countries will account for 37 per cent of the projected growth of the world’s urban population between 2014 and 2050. By 2050, India is projected to add 404 million urban dwellers, China 292 million and Nigeria 212 million. With nearly 38 million people, Tokyo tops UN’s ranking of most populous cities followed by Delhi, Shanghai, Mexico City, São Paulo and Mumbai

These maps will help you comprehend the urban growth that is transforming countries worldwide. Photo by Charlie Ma/Flickr. We are living in the midst of the urban century. Though it is common knowledge that the world is urbanizing, it can be striking to visualize this growth on a map. Graphic by Unicef. As seen in the animation, a number of African countries will go from less than 25% urban in 1950 to more than 75% urban in 2050. Image by Valerie Pieris. Asian countries are undergoing a century-long rural to urban migration. Some of this urban growth is concentrated in megacities According to the United Nations, there were ten megacities with ten million people or more in 1990. Graphic by Statista. As they grow in population, many of the world’s biggest cities have rapidly growing urban footprints. Image by The Telegraph. Rapid growth is also happening in smaller cities The world’s urban growth is not limited to megacities.

Alan Gilbert By the year 2000, the world will contain 28 mega-cities with more than eight million people each (UNDIESA and UNU, 1991: 6). The sheer number of people living in Latin America's mega-cities is not the only reason for looking at them carefully. Table 1.1 Latin America's giant cities, 1995 Source: United Nations, Department of International Economic and Social Affairs, 1995:132 9. The Lima of today, with its population of five million, has changed Peru and these changes are also its problems - because Lima is a problem difficult to unravel. What is a mega-city? Mega-cities are "cities that are expected to have populations of at least eight million inhabitants by the year 2000" (UNDIESA, 1986: iii).

Megacities, not nations, are the world’s dominant, enduring social structures — Quartz Back in June, NASA tested a booster for the most powerful rocket it has ever tried to build, the Space Launch System (SLS). The booster alone was more than 150 feet long, producing 3.6 million pounds of force, and reaching temperatures of nearly 6,000°F during a ground test in Promontory, Utah. The whole rocket is so expensive it will probably only fly twice in the next four years, if at all. A month later, in the Mojave Desert, a very different test took place, involving a prototype rocket just 12 feet long. If its designers are right, the Vector 1, as the small rocket is called, will fly hundreds of times before the SLS becomes operational, making the company a bundle along the way. The buzz in the space business isn’t always about bigger rockets and farther journeys. Just a little lift Advances like these make it possible to do more with smaller satellites, a key savings in a business where installing your infrastructure costs—at a minimum—thousands of dollars per kilogram.
Urban report: Brick and Gold. The Urbanism and Architecture of Informal Belgrade Text: Milica Topalović Photo: ETH Studio Basel & Bas Princen This text is an excerpt from an essay “Brick and Gold: The Urbanism and Architecture of Informal Belgrade” by Milica Topalović in Belgrade.

The book was initiated in 2006 and produced by the ETH Studio Basel Contemporary City Institute and published in 2011 by Verlag Scheidegger & Spiess from Zürich. Periphery Streets are quiet, pedestrian friendly, and yet a pedestrian pavement is missing. Backbones The conceptual gulf between the unstable collectivism of the 1960’s and the ’70’s and the ethos of self realization of the 1990’s corresponds to a physical demarcating space that can be easily followed in Belgrade, even drawn as a map.
