Recent research shows that air quality affects the productivity of high-skilled workers. What does this mean for developing cities?

City governments invest a lot in job creation—they plan infrastructure, skills initiatives, and industry support with the goal to improve productivity and generate jobs and growth, especially in the high-skill sectors. Yet, there might be an important input to productivity that cities can pay more attention to: clean air.

Recent research suggests that a 10-unit increase in the air quality index decreases productivity by 0.35%. Seems marginal? This “productivity slow-down” costs the high-skill economy of China $2.2 billion per year for each additional 10 units of the air quality index.

The research in question studied the effect of air pollution on worker productivity in call centers in Shanghai and Nantong in China. The firm analyzed is Ctrip, one of the largest travel agencies in the country, employing more than 30,000 people. 50% of the workers’ pay is based on performance and the measures of productivity are very detailed and high frequency. The study concluded that there is a robust relationship between daily air pollution levels and worker productivity. On average, a 10-unit increase in the Air Quality Index (AQI) led to a 0.35% decline in the number of calls handled by a worker in a day at an AQI of 100. If we translate this to the entire Chinese high-skill industries, a 10-unit reduction of air pollution levels would increase the monetized value of improved productivity by $2.2 billion per year.

Economic growth in Europe: Leaving no region behind

Ede Ijjasz-Vasquez's picture
Economic growth in most countries is driven by a few urban centers that have a high concentration of economic activity. In the EU, 28 capital cities and 228 secondary cities amass 23% of the total population, generate 63% of total GDP, and were responsible for 64% of GDP growth between 2000 and 2013 (EuroStat). These cities are national and regional growth engines. This is of particular importance for lagging region policies, as it indicates that without strong cities, one cannot have strong regions.
 
This importance of cities for regional and national development now serves as a foundation for the dialogue between the World Bank and the European Commission, with respect to the design of the European Regional Development Fund (ERDF) for the 2014-2020 Programming Period. The ERDF is the world’s largest investment program targeting sub-national public infrastructure investments.
 
In this video, World Bank Senior Director Ede Ijjasz-Vasquez and Marcel Ionescu-Heroiu, Senior Urban Development Specialist from Romania Country Office team, discuss the importance of cities in regional and national growth and development, and the role the Bank is playing in the design of the world’s largest sub-national investment fund.

Why should cities invest in public parks?

Cities are Brazil’s economic powerhouse—they produce almost 90% of the GDP and are the major drivers of the country’s growth and development. Rapid and unplanned urbanization, however, has led to issues such as concentrated poverty, insufficient access to basic services, and a lack of quality public spaces. Public spaces, such as parks, help enhance livability, while also building up resilience to natural disasters, reducing pollution, and enabling inclusive growth.
 
Fortaleza is a coastal city of 2.6 million in the northeast of Brazil. Its sprawling growth has now given way to stark inequality and major spatial divides. Lack of investment and inadequate planning have also led to environmental degradation.

In an effort to address these challenges, the municipality has partnered with the World Bank through the Fortaleza Sustainable Urban Development Project to improve public spaces and rehabilitate areas of the Vertente Marítima Basin and of the Rachel de Queiroz Park. In January 2017, the project was recognized by UN Habitat for innovative practices for the implementation of the New Urban Agenda.

In this video, World Bank Senior Director Ede Ijjasz-Vasquez and Project Lead Emanuela Monteiro discuss the initiative and how it aims to make the city more livable, competitive, and resilient.

A year of building sustainable communities in 12 stories

Andy Shuai Liu's picture
What are some of the key issues that will shape global development in 2017?

​From addressing the forced displacement crisis to helping indigenous communities, and from implementing the “New Urban Agenda” to enhancing resilience to disasters and climate change, one thing is clear: we must step up efforts to build and grow economies and communities that are inclusive, resilient, and sustainable for all—especially for the poor and vulnerable.
 
In the timeline below, revisit some of the stories on sustainable development that resonated the most with you last year, and leave a comment to let us know what you wish to see more of in our “Sustainable Communities” blog series in 2017.

How countries and communities are taking on gender-based violence

The stat is appalling: 1 in 3 women worldwide have or will experience intimate partner violence or non-partner sexual violence in their lifetime.

Although it may take the form of domestic violence, gender-based violence is not merely a personal or family matter. Associated with certain societies' social norms and many other risk factors, such violence leads to severe social and economic consequences that can contribute to ongoing poverty in developing and developed countries alike.

Because violence affects everyone, it takes us all—from individuals to communities, and from cities to countries—to tackle the pandemic of violence against our women and girls.

On Day 15 of the global #16Days campaign, let’s take a look at a few examples of how community groups, civil society organizations, and national governments around the world are making informed efforts to prevent and respond to various forms of gender-based violence.

The “human scale” in public urban areas

"If you lose the human scale, the city becomes an ugly place," said Joan Clos, Executive Director of the UN-HABITAT at the Habitat III Conference last month. But more than being "ugly," the lack of good public urban spaces, such as open spaces, parks, and public buildings, often contribute to low livability in many of the world's congested and polluted cities. In fact, the importance of the issue received recognition in SDG 11, Target 7, which calls for the provision of “universal access to safe, inclusive and accessible, green, and public spaces, in particular for women and children, older persons, and persons with disabilities,” by 2030.
 
Global experience shows that disconnected, underutilized areas in urban settings can, instead, be opened up to a variety of uses to allow for improved social inclusion, social mixing, civic participation, recreation, safety, and a sense of belonging, ultimately contributing to urban prosperity. Well-designed and well-managed public spaces also offer benefits to environmental sustainability, transport efficiency, and public health improvements, and can equally serve women, the disabled, and people of all ages.

The importance of good urban spaces was the topic of an international workshop—“Vitalizing Cities with Public Space”—held in Seoul on November 14-17, 2016 and co-hosted by the Korea Research Institute of Human Settlements and the World Bank’s Urbanscapes Group. Eight cities from around the world—Seoul, Singapore, Buenos Aires, Chongqing, Kakamega, Zanzibar, Astana, and Tashkent—participated to discuss challenges and opportunities for better urban planning and design.

What the New Urban Agenda tells us about building inclusive cities

Over a billion people—about 15% of the world’s population—have disabilities. Almost 80% of them live in the developing world, which is undergoing rapid urbanization.

While urbanization brings people closer to new economic and sociocultural opportunities, persons with disabilities still face a range of constraints in many cities, such as inaccessible buildings and public spaces, limited transportation options, inaccessible housing, and barriers in using technology-enabled virtual environments.

These urban constraints have a significant impact on those living with disabilities in terms of mobility, ability to engage in education and skills development, employability and income generation, and larger social and political participation.

Therefore, urban development must acknowledge and plan for the needs of a diverse population which includes persons with disabilities. And there is no better time than now to make that happen. 

Let’s build the infrastructure that no hurricane can erase

The news from Haiti about the aftermath of Hurricane Matthew is a familiar story: more chaos, rubble, and loss of life from another natural disaster. Though recent improvements to Haiti’s infrastructure at the local level kept the death toll at 534—3,000 died in the 2004 hurricane; more than 200,000 in the 2010 earthquake—the number is still way too high.
 
Worldwide, natural disasters claimed 1.3 million lives between 1992 and 2012, with earthquakes accounting for 60%of disaster deaths in low- and middle-income countries, where the preponderance of sub-standard housing increases the risks. Today, 1.2 billion people live in substandard housing. By 2030, this figure will almost triple.
 
The good news is that most of those deaths and property losses can be prevented. In 2003, for example, within three days of each other, earthquakes of similar magnitude struck Paso Robles, California and Bam, Iran. The death toll in Bam was 40,000—nearly half the city’s population. Two people died in Paso Robles.
 
Even when destruction does take place, proper planning and measures can ensure a speedy recovery.

Information and communication technology (ICT) has expanded the frontiers of connectivity and communication. Nowadays, we don’t think twice before ordering an Uber or using Open 311 to report an issue to our municipality. In the developing world, the impact has been even greater. For example, in Latin America and the Caribbean, cellphone coverage increased from about 12 subscriptions per 100 people in 2000 to over 114 in 2014, and local governments are getting creative in using this technology to reach out to and engage with their citizens.

The city of La Paz in Bolivia is piloting a new tool called Barrio Digital—or Digital Neighborhood—to communicate more effectively and efficiently with citizens living in areas that fall within Barrios de Verdad, or PBCV, an urban upgrading program that provides better services and living conditions to people in poor neighborhoods.

The goals of Barrio Digital are to:
  1. Increase citizen participation for evidence-based decision-making,
  2. Reduce the cost of submitting a claim and shorten the amount of time it takes for the municipality to respond, and
  3. Strengthen the technical skills and capacity within the municipality to use ICT tools for citizen engagement. 

Investing to make our cities more resilient to disasters and climate change

Joe Leitmann's picture

Urbanization comes at a price, especially in an era of climate change and increased risk of natural disasters.

Presently, the average annual loss from natural disasters in cities is estimated by the UN at over $250 billion. If cities fail to build their resilience to disasters, shocks, and ongoing stresses, this figure will rise to $314 billion by 2030, and 77 million more city dwellers will fall into poverty, according to a new World Bank/GFDRR report presented at COP22.

The good news is that we have a window of opportunity to make cities and the urban poor more resilient. Over 60% of the land projected to become urban by 2030 is yet to be developed. Additionally, cities will need to build nearly one billion new housing units by 2060 to house a growing urban population. Building climate-smart, disaster-resilient cities and housing is thus an immediate priority, especially in the developing world. 

To seize that opportunity, countries will need significant financing for infrastructure—over $4 trillion annually—and making this infrastructure low carbon and climate resilient will cost an additional $0.4 to $1.1 trillion, according to a CCFLA report.

Mobilizing private capital is the best bet for helping to close this financing gap.
