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.

Unlocking the transformative power of waterways

Karla Gonzalez Carvajal's picture


Transport history was in the making a few days ago when a Bangladeshi ship carried a consignment of
1,000 tons of steel and iron sheets from the Port of Kolkata in West Bengal to India’s northeastern states, through Bangladesh. This first-ever transshipment of transit goods marked the formal launch of transit trade and transport between India and Bangladesh using a combination of river and land routes. 
 
Senior government officials and top diplomats from both countries, including the Indian High Commissioner in Dhaka, the Bangladesh Minister and Secretary of Shipping, the Senior Secretary of Commerce, and officials of the Bangladesh Inland Water Transport Authority, attended an inaugural ceremony to observe the unloading of goods at Ashuganj Port on the bank of the Meghna River, according to media reports. The general cargo terminal at Ashuganj Port will be rehabilitated and modernized under the newly approved regional IDA project to support Bangladesh’s waterways to handle the loading and unloading of large volumes of cargo.

Helping farmers grow and prosper in Nepal

In Nepal, the Jagattradevi and Tulsibhanjyang areas of the Syangja District are rapidly emerging as leading producers of seed potatoes -- whole or parts of potatoes intended to be re-planted as seeds -- which have traditionally been imported, mostly from India, to meet growing local demand.

Importing seeds from India is costly and time consuming. Therefore, producing seeds domestically is not only a lucrative activity but also a necessity for Nepali farmers, who are also dedicated to growing high-quality seed potatoes.

The Irrigation and Water Resources Management Project (IWRMP) has helped kick start the sustainable production and supply of this important food and cash crop. Since 2008, IWRMP has benefitted about 1,100 households and contributed to improving agriculture productivity and management of selected irrigation schemes in Nepal.

Renewables, solar, and large size projects trending in new data on private participation in infrastructure

Many of you are already familiar with the PPP (Public-Private Partnerships) Group’s Private Participation in Infrastructure (PPI) Database. As a reminder for those who aren’t, the PPI Database is a comprehensive resource of over 8,000 projects with private participation across 139 low- and middle-income economies from the period of 1990-2015, in the water, energy, transport and telecoms sectors.

We recently released the 2015 full year data showing that global private infrastructure investment remains steady when compared to the previous year (US$111.6 billion compared with US$111.7 the previous year), largely due to a couple of mega-deals in Turkey (including Istanbul’s $35.6 billion IGA Airport (which includes a $29.1 billion concession fee to the government). When compared to the previous five-year average, however, global private infrastructure investment in 2015 was 10 percent lower, mainly due to dwindling commitments in China, Brazil, and India. Brazil in particular saw only $4.5 billion in investments, sharply declining from $47.2 billion in 2014 and reversing a trend of growing investments over the last five years.

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.

Who Cares about Running the Buses and Trains on Time?

Tatiana Peralta Quiros's picture
When we evaluate the benefits of public transport projects, we often focus on travel time (in terms of distance covered), vehicle cost savings, accident reductions and environmental impacts (air emissions and greenhouse gas reductions), which are all important dimensions of a project, but not the only ones. The reliability of transport services and information delivery regarding routes, frequencies and arrival time at each station, is not frequently included in the benefits of transport projects because it is difficult to gauge the significance and value of even a 5-10 minute difference in waiting time.
 
In light of this challenge, we began to explore the following question: what are the real implications of waiting time, frequency and reliability of transport systems in terms of improving access to urban opportunities such as education and health services?
 
In a series of blogs, we introduced a new tool that helps us quantify urban accessibility to such services. This tool allows us to calculate how many opportunities -be it jobs, schools, hospitals- become more accessible using public transport. The tool is also useful for comparing various transportation scenarios, modes of transport, service and infrastructure plans, as well as for better understanding land use and spatial patterns.

Is the (Developing) World Ready for the New Container Weight Regulations?

Perikilis Saragiotis's picture
A major change in the way containers’ weight is measured and certified, is fast approaching. As of July 1, 2016, all shipping containers will be required to verify their gross mass before they can be loaded onto a vessel. Previously, shippers could accept weight estimates, but now shippers are responsible for weighing cargo, prior to loading.

Real-time data as an early warning signal

Fida Rana's picture

The risks inherent in public-private partnerships (PPPs) are real. These long-term projects require substantial investment: typically, PPP project funding structures constitute 70 to 80 percent debt, with the remaining coming from equity sources. Because of the nature of these projects, their loan repayment profile demands a longer tenor. In a practical sense, once lenders start disbursing funds to a PPP, the loans could remain on their balance sheet for around 20 years. This is a typical scenario.

For such prolonged engagement in PPP projects, lenders’ ability to monitor the project during the construction and operation phase becomes critical. The approach to monitoring we’ve been offered so far serves its purpose up to a point, but promising developments in real-time data monitoring have the potential to serve as effective early warning signals—assuring the success of a PPP in ways that could revolutionize certain sectors.
