  • The Real Urban Jungle

    How well do you understand life in your own backyard? Cities and suburbs form their own unique ecosystems and ecology, where humans aren’t visitors; they are an integral component, like trees in a forest or coral in a reef. If more than half of the Earth’s people live in cities and the amount of paved surfaces in the United States is equivalent to the area of Ohio, shouldn’t our ...

  • Urban water ecology

    Sewage overflows are a fact of life in urban areas, and in many cities, excess sewage water enters streams and lakes with rain runoff. Although this pollution is harmful to most organisms, there is one group of insects that thrives on it: mosquitoes. Luis Fernando Chaves, a post-doctoral researcher at Emory University, and his team discovered mosquitoes in abundance in a sewage-contaminated ...

  • A healthy urban habitat

    Half the world's population live in cities. By 2050, the total number of urban dwellers is expected to nearly double, rising from 3.3 billion to 6.4 billion1. How do we accommodate urbanisation while ensuring good quality of life and health? How do we minimise environmental damage but still develop our cities? This thematic issue provides a window into the research evidence that can help us ...

  • Mobility Week envisages cleaner air through alternative urban transport

    Over 2000 European towns and cities are expected to participate in the 12th edition of European Mobility Week, which begins today. This year the week runs until 22 September under the slogan ‘Clean air – It’s your move!’. The campaign raises awareness about the impact of transport on local air quality, and encourages citizens to improve their health and wellbeing by ...

  • Careful urban tree planting and pruning needed to reduce trapping of air pollution

    Careful planting and pruning is needed to ensure that air pollution in tree-lined streets is minimised, new research suggests. While planting trees in urban areas can have many benefits, such as enhancing biodiversity, trees can trap particulate matter pollution, say the study’s authors. Particulate matter (PM) air pollution is a component of vehicle exhaust emissions and PM2.5 (particles ...

  • Urban trees could improve air quality, according to EU study

    Planting trees in urban areas could cut particulate pollution in cities by as much as a quarter, according to a new study. Small air particles, especially those less than 10μm in diameter (PM10) pose a long-term threat to human health. These can originate from human activities, including exhaust fumes or smoke, or from natural causes, such as dust. The study shows that trees are particularly ...

  • TODAY: EPA Administrator Media Call to Release Findings on Urban Air Toxics

    Today, at 11 a.m. EDT, U.S. Environmental Protection Agency (EPA) Administrator Gina McCarthy will hold a media conference call to discuss the second and final Integrated Urban Air Toxics (IUAT) Report to Congress. The report highlights the progress and remaining challenges since the release of the IUAT Strategy in 1999 in working with state, local and tribal agencies to help communities ...

  • Sustainability is key to quality of urban life

    A new report suggests that modern urban areas provide high standards of living and prosperity, but are less successful in delivering 'quality of life' to all citizens. If local, national and European authorities focus on sustainable living, they can drive new social, cultural and economic initiatives needed to protect the environment and secure the long-term future of city dwellers. 'Quality of ...

  • U.S.-China collaboration on sustainable urbanization

    A group of government officials from China traveled on a study tour in the United States last week. The tour, hosted by the World Resources Institute, focused on low carbon development. The delegation was led by Director General Su Wei of the Department of Climate Change from China’s National Development and Reform Commission (NDRC), who is China’s chief negotiator on climate change ...

  • Poorest are worst affected by urban expansion

    Rapid expansion of cities has a greater negative impact on poorer inhabitants who cannot afford to move to the outskirts where the air is cleaner, according to a recent study which examined the effects of urban sprawl. Urban sprawl is characterised by rapid, expansive growth of a town or city, which is often driven by uncontrolled development of suburbs at the edges. During this two-part study, ...

  • Urban greening reduces noise pollution

    Green roofs have the potential to significantly reduce road traffic noise in the urban environment, according to a new study. The results suggest that greening of roofs and walls with materials suitable for growing plants softens the urban environment keeping sound levels low, whereas hard, manmade structures tend to amplify traffic noise. The Environmental Noise Directive (2002/49/EC)1 ...

  • Quantifying the ecosystem services provided by urban green spaces

    A new study has quantified the ecosystem services (ES) provided by green spaces in Rotterdam, the Netherlands, using new methods to evaluate high-resolution land-cover data. The findings show that different types of green space provide different ecosystem services, highlighting the importance of careful design during city planning. The authors say their method to map ecosystem services supply ...

  • EPA Report Shows Progress in Reducing Urban Air Toxics Across the United States

    Today (Aug 21, 2014), the U.S. Environmental Protection Agency (EPA) released the Second Integrated Urban Air Toxics Report to Congress - the final of two reports required under the Clean Air Act (CAA) to inform Congress of progress in reducing public health risks from urban air toxics. “This report gives everyone fighting for clean air a lot to be proud of because for more than 40 years we ...

  • CERC holds Advanced Seminar on Regional and Urban Air Quality Management with Fudan University

    Fudan University and CERC held a one day Seminar on Regional and Urban Air Quality management on 23 April at the Fudan University Campus in Shanghai. This seminar brought together top air quality policy makers and practitioners in Shanghai and Yangtzi Delta Region. CERC China Director Dr. Xiangyu Sheng presented CERC’s research work on PM2.5 and recent development of nesting ADMS-Urban with ...

  • State of the World 2007: Earth Facing Urban Future

    WASHINGTON, DC (ENS) – Rapid and chaotic urbanization is taking a massive toll on human health and the environment, the Worldwatch Institute said today in its annual report on the state of the world. In 2008, half of the Earth’s population will live in cities, the first time in history that humans can be considered an urban species. How the world tackles the social and ...

  • Quantifying the ecosystem services provided by urban green spaces

    Urban green spaces provide important ecosystem services in cities, from recreation to the mitigation of noise and air pollution. This study quantified the ecosystem services (ES) provided by green spaces in Rotterdam, the Netherlands, using new methods to evaluate high-resolution land-cover data. The findings show that different types of green space provide different ES, highlighting the ...

  • Climate change raises danger for urban heat islands

    However hot the weather gets, it will be worse in the cities – and scientists in the US have just worked out how much worse by measuring the notorious urban heat island effect. They planted 150 sensors in and around Madison, the Wisconsin state capital, in time for the heatwaves that hit the US in 2012, and found that the city experienced twice as many hours at temperatures above 90° ...
