At this moment you are going to shape the cities for generations to come. People need to realise this is an opportunity that will never come again.

What is Urban Resilience?


100 Resilient Cities

Why do we focus on cities? First, the world is rapidly urbanizing—by 2050, 75% of the world’s population will live in cities. Second, global pressures that play out at a city scale − such as climate change, disease pandemics, economic fluctuations, and terrorism − pose new challenges and uncertainty. Sudden shocks or accumulating stresses in cities can cause significant damage and disruption; in 2011, the cost of natural disasters was estimated at over $380 billion. Because city systems are interconnected, breakdowns can lead to multiple or sequential failure. At worst, this can result in social breakdown, physical collapse, or economic decline.

What makes a city tick? Designing the ‘urban DMA’


Kim Dovey & Elek Pafka, The Conversation, November 2, 2016

When we talk about “urban DMA”, we’re talking about the density of a city’s buildings, the way people and activities are mixed together, and the access, or transport networks that we use to navigate through them.

This is humankind’s ‘great urbanisation’. We must do it right, or the planet will pay.


Dimitri Zenghelis and Nicholas Stern, The Guardian, 8 November 2016

The world will never again build cities as rapidly as it does this century. If we are serious about limiting global warming, tackling air pollution and promoting innovative, resource-efficient growth, there is a narrow window of opportunity.

The rise and fall of great world cities: 5,700 years of urbanisation – mapped


Kanishk Tharoor, The Guardian, 27 June 2016

The Guardian, 27 June 2016

Recent research, published in the journal Scientific Data, transcribed and geocoded nearly 6,000 years of data (from 3700BC to AD2000). The report produced a gargantuan resource for scholars hoping to better understand how and why cities rise and fall – and allowed blogger Max Galka to produce a striking visualisation on his site Metrocosm.

Lee Kuan Yew World City Prize 2016 Laureate: Medellín


Lee Kwan Yew World City Prize, 2016

We live in a time when billions of people are moving into cities. Many of these cities, especially the new mega cities, are very dangerous and disorganised. Many of them are getting worse, and many of them are are looking for role models of cities which have transformed themselves, and no city has done as great a job as Medellín has.

Mapping the ‘Urban Fingerprints’ of Cities


Linda Poon, City Lab, Sep 11, 2015

The most valuable visual information that these maps convey is the density of a particular area. Planned right, a dense city can be a positive environment for productivity. Griffiths explains that the clustering effect creates “agglomeration economies.” “If you cluster a whole lot of people close to each other, with skills that aren’t necessarily the same,” he says, “you get opportunities for new creations.”

A developed country is not a place where the poor have cars. It’s where the rich use public transportation.

Why buses represent democracy in action


Enrique Peñalosa, TED, September 2013

Mobility in developing world cities is a very peculiar challenge, because different from health or education or housing, it tends to get worse as societies become richer. Clearly, a unsustainable model. Mobility, as most other developing country problems, is more than a matter of money or technology, is a matter of equality – equity. The great inequality in developing countries makes it difficult to see, for example, that in terms of transport, an advanced city is not one where even the poor use cars, but rather one where even the rich use public transport, or bicycles.



Gary Hustwit, Swiss Dots, 2011

Ok, here we are in in part of the Porvenir promenade. This is a 24 kilometre pedestrian and bicycle only street which networks very low income neighbourhoods with the richest areas of the city. I think is it a revolution in the way urban life works. This kind of high quality infrastructure for bicycles increases the social status of cyclists. Before we had bicycle-ways low income people were ashamed of using bicycles, now a high quality, protected bicycle-way shows that a citizen on a $30 bicycle is equally important to one in a $30,000 car. 

Global Cities


Aecom Global Cities Institute, 2011

Phoenix has half the population of Hong Kong. but it’s built up area is five time bigger. Hong Kong there can be more than 30,000 people living per square kilometre, it’s over 10,000 in New York, nearly 5,000 in London, and close to 1,200 in Beijing. Hong Kong’s neighbour, Shenzen, has experience a population growth of over 3000% in the past 30 years. In the past 30 years…
