What if…we could help cities more effectively plan a lower-carbon future?

If climate change were a jigsaw puzzle, cities would be a key piece right at the center of it. This was reinforced by more than 100 countries worldwide, which highlighted cities as a critical element of their greenhouse gas (GHG) emission reduction strategies in their national climate plans (aka INDCs) submitted to the UNFCCC in 2015.

Since the ensuing signing of the Paris Agreement, these countries have shifted gear to focus on turning their climate plans into actions. What if, as many of us may wonder, we could find a cost-effective and efficient way to help put cities—in developing and developed countries alike—onto a low-carbon path of growth?

CURB: Climate Action for Urban Sustainability, launched this Climate Week, is an attempt to do just that. A free, data-driven scenario planning tool, CURB can readily help cities identify and prioritize climate actions to reduce carbon emissions, improve overall efficiency, and boost jobs and livelihoods.

A joint vision for effective city planning

What CURB can do for cities owes very much to the inspiration and stories we have taken from them in developing the tool. It was a fortuitous few hours in early 2014 at the C40 Cities Climate Leadership Summit in Johannesburg, South Africa that really got the ball rolling on the development of CURB.

Amina and her family had recently moved to their new house on the outskirts of Dakar, Senegal. It was built by the government to relocate families from low-lying and flood-prone neighborhoods in the city. The house was small for her extended family of ten, but it was water that she worried about. I was puzzled. Usually people complain that water connection costs are too high, but she received that connection for free—the meter and tap were right there in her front yard.

Why did she worry?

Five reasons cities should take a leading role on food waste

John Morton's picture
Reported figures from the Food and Agriculture Organization of the United Nations (FAO) on food loss and food waste highlight its importance to the global environment. Food loss and waste annually contribute 3.3 gigagrams of CO2 equivalent, or over twice the total emissions of India; waste 250 cubic kilometers of water which is equivalent to 100 million Olympic-sized swimming pools; and 1.4 billion hectares of agricultural land, an area larger than China. Considering that, if only 1/4 of the food lost or wasted across the globe could be recovered, it could feed 750 million people, it is also shocking when presented in the context of global food insecurity and hunger.
 
These statistics highlight the need to address the problem as global citizens. But if you look at it closer, the incentives for action are indeed very local, making cities—as the centers of consumption in the world—important game changers with strong reasons to take action.

Building sustainable cities starts with smart urban design

Ede Ijjasz-Vasquez's picture
The global conversation about urban sustainability focuses primarily on the big picture: how to reduce the carbon footprint and energy consumption of cities? How can we provide the infrastructure and services necessary to meet the needs of a soaring urban population? How can cities create enough jobs for everyone?
 
These issues are critically important, no doubt. But what about the city itself as a physical space? What should a sustainable city "look like"? Are there any big design principles that all successful urban planners should follow?
 
Because urbanization is often a chaotic process, many countries feel like they don't have the time or resources to address those questions. Yet evidence has shown that considerations about urban form and design are anything but cosmetic: creating vibrant public spaces within a city, for instance, can boost competitiveness, improve health outcomes, and strengthen social cohesion.
 
In this video, Ede Ijjasz-Vasquez and Jon Kher Kaw delve deeper into the linkages between urban spaces and sustainability, and describe the many benefits that come with a well-designed city.

Can Singapore become a role model for quickly-growing cities?

Ede Ijjasz-Vasquez's picture
In the 1960s, Singapore was struggling with limited resources, a small domestic market, and high unemployment. Living standards were low, with most residents living in crowded, unsanitary slums.
 
Today's picture couldn't be any more different: in the span of just a few decades, the city-state has completely reinvented itself to become a model of urban innovation, consistently topping international rankings for livability and competitiveness.
 
But Singapore's transformation was no happy accident. This success story is the result of an innovative and carefully executed vision that looks at all aspects of urban development in a cohesive way. Singaporean leaders and urban planners have integrated land use, housing, transport, and natural resources management into one coherent, long-term strategy so they can work in sync and reinforce each other.
 
In this video, Ede Ijjasz-Vasquez and Abhas Jha take a closer look at the city's urban development approach, and describe how other countries can draw on Singapore's experience to build sustainable, livable cities.

The Global Urban Footprint: A map of nearly every human settlement on Earth

Thomas Esch's picture


Urbanization is increasingly central to the global development process, but until recently, basic spatial information on the world’s urban areas has been unavailable, inconsistent, or unreliable. The lack of consistent data on the world’s cities makes it hard to understand the overall impact of urbanization. However, innovations in geospatial mapping are now helping to provide one major piece of the puzzle:maps of practically all built-up areas around the world are available thanks to new uses of satellite data.
 
Scientists at the German Aerospace Center (DLR) have succeeded in using a newly developed method to map the world’s built spaces at an unprecedented spatial resolution, resulting in the ‘Global Urban Footprint’ (GUF), a global map of human settlements at a spatial resolution of 12 meters per grid cell (aggregated to 75m for public use).
 
The German radar satellites TerraSAR X and TanDEM X acquired over 180,000 images between 2010 and 2013, which were processed, together with additional data such as digital terrain models, to produce the Global Urban Footprint. In total, the researchers processed over 20 million datasets with a combined volume of more than 320 terabytes.

Can transit-oriented development change travel behavior in cities?

It is pretty easy to understand how and why land use patterns around public transit stations can influence the way we move around the city.

As more and more people live and work in a neighborhood with a limited land area, it becomes increasingly challenging to drive around without encountering congestion or to find a parking space easily. In this situation, public transit and non-motorized transport (NMT) become attractive alternatives for people who otherwise are reluctant to give up the comfort and flexibility of driving.

Conversely, as street blocks get bigger, people may find it takes too long to access public transit stations, which discourages the use of public transport facilities.

As straightforward as the logic may sound, the nature and magnitude of such influence are yet to be evaluated with solid empirical evidence. To take a closer look at the linkages between land use and travel behavior, I decided to study the case of Boston in the United States. I chose Boston because it boasts an effective public transit system, and was one of the first American cities to embrace transit-oriented development (TOD), an urban planning approach that promotes compact and mixed use development around public transit facilities.

Of tigers and elephants: The rise of cities in Asia

Over the next decade and a half the world will add a staggering 1.1 billion people to its towns and cities. About one half of this urbanization will happen in the regions of East and South Asia.
 
If history is any guide, this growth in urban population will provide tremendous opportunities for increasing prosperity and livability. One can look at the successes of a few Asian cities such as Tokyo, Seoul, and Singapore to demonstrate how, with the assistance of good policies, urbanization and economic development go hand-in-hand. More generally, no major country has ever reached middle-income status without also experiencing substantial urbanization.
 
Yet cities can grow in different ways that will affect their competitiveness, livability, and sustainability. The more successful cities of Asia have been effective at creating opportunities, increasing productivity, fostering innovation, providing efficient and affordable services for residents, and enhancing public spaces to create vibrant and attractive places to live. But many, many, more cities have neglected fundamental investments in critical infrastructure and basic services, and have mismanaged land, environmental and social policies. This has resulted in traffic congestion, sprawl, slums, pollution, and crime.
 
Among the many complexities of urban development that have contributed to success, two critical factors stand out – investing in strategic urban planning, and in good urban governance.

Can other cities be as competitive as Singapore?

Singapore is an example of one of the most competitive cities in Asia and in the world. Many, many other cities want to be the next Singapore. In fact, Singapore has been so successful that some believe that its success cannot be emulated. They forget that in the 1960s, Singapore faced several challenges – high unemployment, a small domestic market, limited natural resources, not to mention that most of the population lived in overcrowded unsanitary conditions in slums. Challenges that would sound very familiar to a large number of cities in the developing world.

And so, what better place than Singapore for the Asia Launch of the Competitive Cities for Jobs and Growth: What, Who & How report. The World Bank Group, along with the Centre for Liveable Cities and International Enterprise Singapore co-sponsored the launch as part of Urban Week held in Singapore from 8-11 March, 2016. The roundtable was attended by over 100 delegates representing cities from 23 countries.

The competitiveness potential for cities is enormous. Almost 19 million extra jobs, annually, could be created globally if cities performed at the level of the top quartile of competitive cities. Of this potential, more than 1/3, i.e. equivalent to an additional 7 million jobs, comes from cities in East Asia. Between 2000 and 2010, nearly 200 million people moved to East Asia's urban centers – these people will need jobs. Where will these jobs come from? How will they be generated?

Singapore: The Pelé of urban design

Who is the best soccer player of all time? A Google search will offer this name: Edson Arantes do Nascimento, popularly known as Pelé. Kicking off in 1958 as a 17 year old World Cup winner, Pele bookmarked his brilliant career a dozen years later with another World Cup triumph for Brazil. 
 
I like to think of Singapore as the Pelé of urban design. The city regularly appears in the top ranks of globally livableconnected and competitive cities. Pelé once famously said, "Success is no accident. It is hard work, perseverance, learning, studying, sacrifice, and, most of all, love of what you are doing or learning to do”. There is no doubt that Singapore’s accomplishments have been made possible by the hard work, perseverance and far-sightedness of its policy makers.
 
2013 speech by Peter Ho, Chairman of the Urban Redevelopment Authority, outlines the careful thought, planning and attention to detail behind Singapore’s urban policy, particularly the decisions, influence and foresight of Mr. Lee Kuan Yew over the decades of development. One astonishing success has been the provision of affordable housing and the care with which each neighborhood has been designed, taking care of the smallest details, in order to ensure social cohesion and a sense of community. These details include provisions for hawker centers and high quality public green spaces.
