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.

To build resilient cities, we must treat substandard housing as a life-or-death emergency

The scene is as familiar as it is tragic: A devastating hurricane or earthquake strikes a populated area in a poor country, inflicting a high number of casualties, overwhelming the resources and capacity of rescue teams and hospital emergency rooms. First responders must resort to “triage” – the medical strategy of maximizing the efficient use of existing resources to save lives, while minimizing the number of deaths. 

But if governments could apply triage to substandard housing, medical triage would be a much less frequent occurrence – because in the developing world, it is mainly housing that kills people, not disasters.
 
Worldwide, most injuries and deaths from natural disasters are a result of substandard housing. In Latin America and the Caribbean, for example, one-third of the population – 200 million people – lives in informal settlements, which are densely packed with deadly housing units. In 2010, when the 7.0-magnitude Haiti earthquake killed 260,000 people, 70% of damages were related to housing. Similarly, it’s estimated that if an 8.0-magnitude earthquake hit Peru, 80% of the economic losses would be to housing.
 
But the story in rich countries is different. In the past 10 years, high-income countries experienced 47% of disasters worldwide, but accounted for only 7% of fatalities.

Cleaner streets mean healthier communities: The story of the “Zika Warriors”

Last November, 345 “Zika Warriors” took to the streets of Jamaica to fight the spread of the Zika virus in 30 communities. These local residents trained as vector control aides to prevent Zika primarily by improving waste management in their communities, including cleaning up public spaces and destroying mosquito breeding sites. In addition, they distributed bed nets to pregnant households.

As we observe World Health Day today, we look back with great thanks to the significant reduction in Zika in these communities. Anecdotal evidence suggested that the Zika Warriors significantly stemmed the spread of the virus, especially compared to the 2014 Chikungunya outbreak that led Jamaica to declare a state of emergency.

As a first responder to the pandemic, the Jamaica Social Investment Fund (JSIF) designed this program within an existing waste management program of the World Bank’s Integrated Community Development Project, directly benefitting more than 140,000 citizens.

All I need is the air that I breathe…

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.

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. 

Planting healthy air: a natural solution to address pollution and heat in cities

Can nature help cities address the twin problems of air that is too dirty or too hot? Based on a new report released by The Nature Conservancy – in collaboration with C40 Cities Climate Leadership Group - the answer appears to be a qualified “yes.”
 
The Planting Healthy Air report identifies the potential return on investment from tree planting in 245 global cities, which currently house about a quarter of the world’s urban population. By collecting and analyzing geospatial information on forest and land cover, particulate matter, and population density and leveraging existing literature, the study estimates the scope of current and future street trees to make urban air healthier. The benefits that trees could afford to cities will be even more crucial in the future, the study finds, as a quarter million people could die each year because of urban heat by 2050, unless cities take proactive steps to adapt to global warming.

Five ways to increase citizen participation in local waste services

Web platforms, apps, and citizen surveys are changing how solid waste management services are conducted globally and showing that waste infrastructure alone is simply not enough. These interactive platforms provide incentives, quantify actions, and increase pressure on service providers, and thereby improve waste management with greater citizen engagement.
 
The World Bank recently hosted five individuals representing organizations and projects that use information and communications technology (ICT) to engage citizens with local waste services. Their varied approaches reveal incentive models that effectively lead to strategic behavior change.
