Let’s say you are a transport specialist or an urban planner who wants to implement a transit-oriented development plan, because you know that TOD, as a planning and design strategy, can help transform your city.
TOD, as an urban development approach, concentrates high-density development and economic clusters around rapid transit stations. Concentrating housing and activities such as jobs, within a 5 to 10-minute walking distance from these stations encourages more people to take public transport and reduces the need for motorized trips. In addition, if done well, TOD enhances universal accessibility and the quality of public space while offering green and efficient urban mobility options.
Although these all sound attractive for you to implement your plan, you need to convince others, including the city officials you are working with. How do you do that?
The discussion on climate change often tends to ignore one critical factor: people’s own habits and preferences. In urban transport, the issue of behavior change is particularly important, as the transition to low-carbon mobility relies in large part on commuters’ willingness to leave their cars at home and turn to greener modes such as public transit, cycling, or walking.
Getting people to make the switch is easier said than done: decades of car-centric development, combined with the persistence of the private car as a status symbol, have made it hard for policymakers to take residents out of their vehicles.
Against this backdrop, I was inspired to learn about the example of Suwon, Gyeonggi Province, a city of 1.2 million some 45km south of Seoul I visited on my last trip to the Republic of Korea.
Officials in Suwon have realized that, although awareness of climate change is becoming widespread, behavioral engagement hasn’t quite caught up. To overcome this challenge, the city decided to make sure residents could be directly involved in the design and implementation of its urban transport strategy.
When I used to work in Rwanda, I lived on a small street in Kigali. Every time I invited friends over, I would tell them to “walk past the Embassy, look out for the Church, and then continue to the house with the black gate.” The day a street sign was erected on my street was a game changer.
So how do more than two million citizens of Accra navigate the busy city without the help of street names? While some street names are commonly known, most streets do not have any official name, street sign or house number. Instead, people usually refer to palm trees, speed bumps, street vendors, etc.
But, what happens when the palm tree is cut or when the street vendor changes the location?
The absence of street names poses not only challenges for orientation, but also for property tax collection, postal services, emergency services, and the private sector. Especially, new economy companies, such as Amazon or Uber, depend on street addressing systems and are eager to cater to market demands of a growing middle class.
To address these challenges, the Accra Metropolitan Assembly (AMA), financed by the World Bank’s second Land Administration Project , is implementing a street addressing and property numbering system in Accra. Other Metropolitan areas received funding from other World Bank-funded projects for similar purposes.
Public spaces such as streets, open spaces, parks, and public buildings are a big part of cities that are often overlooked. Inadequate, poorly designed, or privatized public spaces often generate exclusion and marginalization and degrades the livability of the urban environment. That is why the importance of public spaces are now embedded within the Sustainable Development Goals.
In dense built-up cities like Karachi, Pakistan, public spaces are even more important. These are areas of respite and recreation from the stress of city life. They are also social and cultural spaces where livelihoods and businesses are conducted, especially for the urban poor. Public open spaces in Karachi have suffered from rapid urban growth:
The total share of green space detectable in satellite imagery has fallen from 4.6% in 2001 to 3.7% in 2013.
Large tracts of vacant land in prime areas in the city center are closed off to the public and neglected.
Twelve square kilometers of prime waterfront area, often a valuable public asset in other cities, is still mostly undeveloped more than 10 years after the roads were built.
Many sidewalks in the main commercial areas and busy corridors are broken down, converted to unregulated parking areas, or used for dumping trash—to the detriment of pedestrian safety and public health.
In a focus group, women also remarked on the lack of safe playgrounds or other recreational facilities for children.
Recently the World Bank Group approved a loan for the Karachi Neighborhood Improvement Project (KNIP) to finance improvements in public spaces in the city’s selected neighborhoods and to strengthen the city government’s capacity to provide certain administrative services such as business registration and construction permits. The investments in safety, walkability and access to public transit nodes are also timely, given the city’s plans to introduce a system of Bus Rapid Transit within the city and in two of the three neighborhoods.
Beyond the investments in the physical space and urban design, a key design feature of KNIP is its emphasis on active and sustained engagement with the residents of Karachi. The project aims to use a participatory planning process to identify, prioritize, and design highly impactful enhancements to public areas such as sidewalks, open spaces and green spaces, and public buildings. While the exact nature of investments will be determined through community consultations, they may include safety features for pedestrians and other non-motorized transportation, accessibility and mobility improvements close to commercial areas and planned transit stations, new or upgraded neighborhood parks and playgrounds, infrastructure to foster safe and vibrant street activity (kiosks for vendors, tables and seating, temporary street closures for festivals, etc.), measures to address traffic congestion and parking, and improved municipal services in public areas (street lighting, garbage collection, drainage, etc.).
KNIP is intended to be an entry point to showcase the value of participatory planning and inclusive urban design, as the first step in a longer-term strategy for city transformation and rejuvenation. Building confidence and inclusiveness in city management is critical to ensure the success of deeper institutional reforms and larger infrastructure investment programs down the road. KNIP is expected to help lay the foundation for a multi-year partnership between the World Bank Group and the local and provincial governments focused on inclusivity, livability, and prosperity. To this end, KNIP will also support the creation of a Karachi Transformation Steering Committee (KTSC), comprised of elected officials, government representatives, business leaders, community stakeholders and NGOs representing various public interests. KTSC’s mandate is to develop a shared vision for Karachi’s transformation and a roadmap to achieve that vision in an inclusive way.
It will take Karachi as much as $10 billion of capital investment over the next decade to close the infrastructure gaps in the city.
On the ground, it is not too difficult to see why this is so. More than 40% of residents rely on public transport, but with 45 residents competing for one bus seat, travel within the city is difficult. Water supply is highly irregular, and rationing is widespread. The availability of water ranges from four hours per day to two hours every other day. Many households rely on private vendors who sell water from tankers at high prices. The sewage network has not been well maintained since the 1960s, and all three existing treatment plants are dysfunctional. Industrial waste, which contains hazardous materials and heavy oils, is dumped directly into the sea untreated. Of the 12,000 tons of municipal solid waste generated each day, 60% never reaches a dumpsite; 80% of medical waste is not disposed of properly.
When a family of 10 smooth-coated otters appeared in Singapore’s urban downtown of Marina Bay last year, the city was ablaze with excitement and delight. Who would have thought that these otters would make a dense urban environment like Singapore home? After all, otters were thought to have vanished in the 1970s as Singapore rapidly developed into a dense metropolis.
Was this a fad? Probably. Was this a big deal? Absolutely. In a small city-state where land is considered a scarce resource, the tension between urban development and biodiversity conservation can be very pronounced. This was not the case in Singapore. Between 1986 and 2010, as Singapore’s urban population doubled from 2.7 to 5 million, its green cover also increased from 36% to 50%, all within the confines of just 710 square kilometers. The increase in green cover in urbanized Singapore was seen as a sign that the efforts by the urban planning agency, parks and water management boards had paid off, and a testament that the natural environment could be indeed be integrated effectively into the urban fabric of the city.
Today is World Environment Day. This year, it celebrates the theme of “connecting people to nature,” and invites us to think about how we are part of nature—and how intimately we depend on it.
Paraisópolis, a nationally famous slum area in São Paulo, Brazil, is one of those bustling communities where everything happens. Despite being located in the middle of the city, it managed, unlike other poor slum areas, not to be reallocated to make room for more expensive housing or public infrastructure. The area boasts vibrant community life, with more than 40 active NGOs covering issues that range from waste management and health to ballet and cooking. Recently, the area also benefited from several community upgrading programs. In particular, investments in local roads have facilitated truck access to the community, bringing in large and small retailers, and generating lively economic activity along with job opportunities for local residents.
As we continue our efforts to increase awareness around on-foot mobility (see previous blog), today, I would like to highlight a project we developed for Paraisópolis.
While most of the community has access to basic services and there are opportunities for professional enhancement and cultural activities, mobility and access to jobs remains a challenge. The current inequitable distribution of public space in the community prioritizes private cars versus transit and non-motorized transport. This contributes to severe congestion and reduced transit travel speed; buses had to be reallocated to neighboring streets because they were always stuck in traffic. Pedestrians are always at danger of being hit by a vehicle or falling on the barely-existent sidewalks, and emergency vehicles have no chance of getting into the community if needed. For example, in the last year there were three fire events—a common hazard in such communities—affecting hundreds of homes, yet the emergency trucks could not come in to respond on time because of cars blocking the passage.
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.

As per NASA’s definition, global warming is “the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels.” This increase in temperature has grown exponentially in recent times. According to a World Bank report, warming of close to 1.5°C above pre-industrial times is already locked into Earth’s atmospheric system by past and predicted greenhouse gas emissions.
This rise in temperatures is most notable in cities due to the so-called “urban heat island” effect. This is caused by the concentration of people, vehicles, buildings and machinery, all of which generate heat. However, the biggest contributor to the urban heat island effect is the replacement of plants by concrete, according to the Smithsonian’s article.
Deforestation and increased pollution have caused Paraguay’s capital Asunción to be recognized as the hottest city in the world. World Wildlife Fund had an interesting idea to raise awareness amongst Paraguayans about the dangerous effects of global warming. With a local chef, they organized an outdoor restaurant with a “Global Warming menu” cooked directly on the hot asphalt of the street.
As traffic congestion continues growing in urban areas, more and more cities have realized that investment priority should be given to public transport modes, such as metro trains, bus rapid transit systems (BRT) or buses, instead of personal vehicles. Simply put, public transport modes are more efficient than personal vehicles in terms of carrying and moving people around. However, international experiences also tell us that building more metro lines or putting more buses on the road alone may not be able to get more people to use public transport modes.
There are several non-transport factors, or urban design factors, that play a critical role in a traveler’s decision on their best travel mode.
The first critical factor is density. As illustrated in a famous study done by Alain Bertaud, a former World Bank staff, density is the primary reason why 30 percent of daily trips are carried out by public transport in Barcelona, but only four percent in Atlanta. Barcelona is about 30 times denser than Atlanta, so it is therefore much easier to provide same level of public transport services in Barcelona than Atlanta.
One lesser-known factor is accessibility. Just having a high population density may not guarantee more people to use public transport.
