China's 4 Most Wasteful Infrastructure Projects of 2012 - Naomi Rovnick

There has been no major announcement of a multi-trilllion dollar stimulus package this year, but all the signs are that Beijing is pressing its foot down hard on the pedal to kickstart job creation and boost GDP growth. Here is one rundown of this year’s ongoing road, rail and subway projects. The problem with construction for its own sake is that it can create waste, as well as very high debt and possibly the next global credit crisis. China has been building ghost towns for years, and journalists have already written a lot on well-established empty cities such as Ordos in Inner Mongolia and Chenggong, in the southwestern province of Kunming. But like a neverending vaudeville show, the bizarre hilarity of Chinese overbuilding never stops. 1. 2. 3.

Why Africa Should Be Wary of Its ‘New Cities’ Planned, self-contained cities are popping up all over Africa, and no one knows what their impact might be.

Why Africa Should Be Wary of Its ‘New Cities’

In this guest blog post, Nairobi-based urban practitioner Jane Lumumba argues they might only make social and economic problems worse. Africa is bracing itself for the arrival of the New Cities. That’s the term being used by urban scholars to describe the continent’s next urban phenomenon: Comprehensively planned, independent, relatively self-contained communities, usually built from scratch, and large enough to provide within their borders housing, public facilities, socio-cultural opportunities and employment for their residents.

Some scholars have gone so far as to call the New Cities “urban villages,” distinguishing them from a “normal” city that gradually grows and evolves over time. New City projects emerging in Africa are planned urban areas, usually on the periphery of an older city, designed to meet their own residential, commercial, industrial and retail needs.

Construis ta cité médiévale

Sur les terres du seigneur ou du monastère, de petits villages se regroupent autour d'une église. Pour assurer leur protection, leur seigneur a fait bâtir son château fort. La population se divise en trois groupes où chacun trouve une place et un rôle : les gens du peuple, les nobles et les religieux. Au fil de la période, les villages évolueront pour se transformer en villes. Te voici à la tête d'une simple terre pourvue de forêts et d'un donjon sur une colline. Urban TV Guide. The Atlantic Cities. Urban Times - Be the Change. The chaos of megacity supply chains, mapped. Researchers at MIT have embarked on a seemingly impossible task: tracking supply chains in some of the most chaotic megacities in the world.

The chaos of megacity supply chains, mapped

MIT’s Megacities Logistics Lab gathered data on the supply chains -- such as how many and what kinds of vehicles were used to make deliveries, where they parked, and how it impacted traffic -- in cities like Rio de Janeiro and Beijing and made the information available through an open-source web platform. But what's the point of mapping megacity logistics other than creating something that could be confused with abstract art?

According to Edgar Blanco, research director at MIT’s Center for Transportation and Logistics and the project lead, it's not information that cities have been able to keep track of, especially cities with booming populations.

How Cities Are Preparing for the Challenges of Climate Change - Intelligent Cities

The North Sea flood of 1953 was the result of a high tide meeting an unusually strong storm — the same combination that made Superstorm Sandy so destructive — resulting in a coastal surge that inundated the countries around the North Sea. Lives were lost in England, Scotland and Belgium, but the most severe impact was felt in the Netherlands. The old dikes and other sea defenses built around the Dutch coast proved powerless to stop the surge. ICLEI Global. See America's Great Cities in an Interactive Map Extravaganza.
