4 New Ways Of Thinking That Should Shape The Next Century Of Cities

4 New Ways Of Thinking That Should Shape The Next Century Of Cities | green streets |
In order to thrive over the next century cities will have to change. Here's how.

Last week, the Ditchley Foundation in Oxford, England, hosted over 30 academics, practitioners, government, and non-governmental organization leaders from five continents to contemplate the rapid urbanization of the globe and address challenges and opportunities across multiple geographies, economies, and political landscapes.

Visit the link to find specific insights and processes that could significantly shape how we think about global cities over the next century.

Stephane Bilodeau's curator insight, December 17, 2013 5:27 PM

The Internet, big data, and social media should result in more responsive planning, better service delivery, and broader citizen engagement. Technology should redefine transportation to seamlessly marry centrally scheduled buses and trains with more spontaneous options such as car and bike sharing, as well as the informal systems of cabs, motorcycles, and rickshaws that dominate in many developing countries. Ubiquitous, open public, and private data should make human health and well-being as easily and regularly measured as GDP.

We still seem to be looking at our 21st-century cities largely through a 20th-century lens. This is limiting the alchemy, not catalyzing it. Urban planning remains largely focused just on the physical environment, not on socio-economic results. Community is moving towards becoming a question of 'geographic cohesion,' not geographic place in a traditional sense. There was great conversation about not trying to retrofit old models of working, but rather adapting the way people and cities work with newly available channels and technologies.

Eli Levine's curator insight, March 6, 2014 12:15 PM

Fascinating, and intuitive.


A nation is just a network of cities, connected economically, socially and culturally.  A region of the world is just a network of interlaced economic forces that can either be for the benefit (the EU or ECOWAS) or the detriment (NAFTA) of the people who live in the territories under the given region.  The same could be said about strategic partnerships (NATO or the AU).


Combine it all together, and you've got the planet.


"The control of a large force is the same principle as the control of a few men: it is merely a question of dividing up their numbers."       -Sun Tzu


What works on the city level may be applicable to the nation, the region and the world as a whole.


Think about it.

20 Smart City Technologies for 2013 and Beyond

20 Smart City Technologies for 2013 and Beyond | green streets |

Santiago Chile announced they’re going to become a “smart city” in 2013, and is just one example of a growing number of areas around the globe preparing and modernizing for the future.

In fact demographers have long predicted the mass urbanization of metropolitan areas across the world. According to the United Nations, by the year 2050, 80% of the world will be living in urban areas. The equivalent of seven Manhattan size cities will be built each year until 2050. For these cities to thrive they must use smart technology to its fullest. Let’s take a look at what’s available now and what’s coming down the pipe...

This article and list goes over tons of new urban ideas that have a lot to do with sustainability and new urbanism. It shows a lot of energy efficient services and smart technology.


This connects to the Unit 7 TEK on new urbanism because it shows how urban places are changing for the future and how urban areas working toward sustainability may look in the future. It gives insight into some incoming or possible smart technologies.

Ricardo Cabeza de Vaca's curator insight, May 27, 2015 2:23 AM

I think this article gives us a peek into the future. As cities develop so does technology. This shows us as technology improves so does the lifestyle of the people from the city. This article talks about how technology could for example improve security in the area by facial recognition and you could have urban farming by using vertical farming.  I believe that we should invest more into technology as it will help us tremendously now and in the future, letting us as the article says for example wirelessly charge every car in the city.

Making Smarter Cities | The Atlantic

Making Smarter Cities | The Atlantic | green streets |
As population growth drives urbanization, the environmental impacts of cities are becoming increasingly important. By 2050, some 90% of the U.S. population and 70% of the world population will live in cities, according to the University of Michigan's Center for Sustainable Systems.

As a result, interest in "smart cities" that provide technologically advanced services and infrastructure is increasing: The global smart city market is projected to cross $1 trillion in 2016, with players such as IBM and Accenture leading the way.

"Successful cities will need to differentiate themselves to attract investment and productive residents," said Ruthbea Yesner Clarke, Research Director of IDC's Smart Cities Strategies, in a recent report. Constrained financial resources, fast-growing populations, and aging infrastructures are driving investment in smart cities, she said.

Can China Support Its New Urban Majority?

Can China Support Its New Urban Majority? | green streets |

By the end of 2011, the population in China was about 1.35 billion. Roughly 51.27 percent of that, 690 million people, are considered urban, according to a recent announcement from China’s National Bureau of Statistics. It’s an interesting landmark, but also slightly troubling in light of another official report that warns of "grim" threats from climate change...

Visualizing Sustainable Urbanization

Visualizing Sustainable Urbanization | green streets |

In a Sustainable City, the use of renewable resources is emphazised, resource consumption is minimized and resources are managed in a way that maximizes recovery and reuse.
New system solutions provide scope for synergies between sewage, waste and energy production and enable coordination with efficient land use, landscape planning and transport systems. This is illustrated by the eco-cycle model which is essential for a definitive shift from linear to circular resource flows.

Emily Bian's curator insight, May 22, 2015 9:27 AM

Sustainability is the survival of the environment to be able to sustain future generations. Environmental sustainability is a critical issue due to mass consumption, pollution, climate change, and things like deforestation and desertification. 

People are using more renewable resources and trying to cut down on mass consumption. 

This is a good diagram and article to read for APHUG students for them to learn about sustainability and how that affects the people living on this earth. 

Anna Sasaki's curator insight, May 27, 2015 3:08 AM

Sustainability derives from the utilization of renewable resources. There are new and improved methods of the disposal of waste and more eco-friendly ways of transportation and landscape planning. This model insinuates the different ingredients needed to create a sustainable city.

This ties into master planned cities, since the cities have to take into account these fundamental rules of sustainability, as well as the small details which could potentially have grand repercussions.

Urban Design for New American Cities

Urban Design for New American Cities | green streets |

Around many of our Gateway Cities like New York, Washington DC and San Francisco, are sprouting "New Cities", complete with their own infrastructure, neighborhoods, employment centers and cultural identity.

With exploding global populations, much of the talk around urbanization revolves around cities in Asia, Africa and Latin America. But here at home in the United States, a new type of city form is taking shape. Around many of our Gateway Cities like New York, Washington DC and San Francisco, are sprouting "New Cities", complete with their own infrastructure, neighborhoods, employment centers and cultural identity.

The timing of these "New Cities" is good, since in recent years there has been a resurgence of ideas of urban planning that promote mix of uses, walkability and transit oriented development. However, New Cities confront us with many unprecedented realities that we must consider and analyze in depth before we rubber-stamp our current formulas for creating vibrant urban communities. These places are inherently different from Gateway Cities, Suburban Settlements or Rural Areas. They have a DNA of their own, which requires a more tailored response...

Ricardo Cabeza de Vaca's curator insight, May 26, 2015 9:00 PM

I believe this article is very interesting. It reminds us that because of changing times we also need to change the demographics of our cities. With exploding populations it is time to come up with a "New City' a different type of city with a new type of infrastructure. Around huge population centers these new cities are popping up and are creating a very different environment. These cities are creating permanent, affordable and very diverse places to live. They are creating a positive place for the people that move to these cities. A city of the future and for the future.

How will our future cities look?

How will our future cities look? | green streets |

Almost half of the world's population currently lives in cities, and by 2050 that is projected to increase to 75%, but what kind of city will they be living in?

The time is ripe, say experts, to start designing smarter urban environments, both new cities needed to sustain an ever-growing population, and retro-fits on the ones that we have lived in for centuries.

So, how do we make our cities stronger?

Some of these revolve around the idea that smarter equals greener. Sustainability experts predict carbon-neutral cities full of electric vehicles and bike-sharing schemes, with air quality so much improved that office workers can actually open their windows for the first time.

Visions of a green city often include skyscrapers where living and office space vie with floating greenhouses or high-rise vegetable patches and green roofs, as we try to combine urbanisation with a return to our pastoral past...

Urban Sense: Smart, Sustainable "Insta-Cities": A Prototype

Urban Sense: Smart, Sustainable "Insta-Cities": A Prototype | green streets |

On October 31, the world’s population hit the 7 billion mark. In an era of rapid population growth and the rapid urbanization of the world, some parts of the world find themselves needing more cities—and fast. China is building at a staggering pace – a new city “the equivalent to Rome every few weeks” 

So what are developers and the technology industry doing to make these new, almost “pre-fab” cities sustainable?

Enter Korea’s Songdo International Business District. This brand new city is unfurling itself on land reclaimed from the Yellow Sea. When completed (in 2016), Songdo will be the size of Boston, ready for one million or more residents. Songdo will be a cutting-edge “smart city” with everything from trunk lines to lighting fixtures wired to collect data that will enable companies and residents to monitor and control virtually every piece of urban infrastructure--including water and electricity. This city is to be a prototype of a “city in a box” that will be replicated twenty times in China and India in the coming years...

Jacob Waters's curator insight, February 10, 2014 10:11 AM

This loose idea of a "Insta-Cities" or what I call "Jack-In-The-Box-Cities"  is a good step toward the future being that you can build a city in the event of a population boom or relocation a city can be built in relativity short time. However the cost of a city, and the cost in my opinion would probably non-appealing, and a techolgy  city what mostly runs on computers could be hacked or materials could be lost in the event of a mishap. All in all it is still a prototype.
