New research has found that in 15 major cities in the global south, almost half of all households lack access to piped utility water, affecting more than 50 million people.
New research shows that visitors to urban parks use happier words and express less negativity on Twitter than before their visit -- and that their elevated mood lasts for up to four hours. The effect is so strong that it's equivalent to the mood spike on Christmas, the happiest day each year on Twitter. With increasing urbanization and mood disorders, this research may have powerful implications for public health and urban planning.
Researchers: Reductions in violence might be increased if focused-deterrence programs can enhance network diffusion.
A new in-depth study from Ryerson University called 'The influence of environmental and health indicators on premature mortality: an empirical analysis of the City of Toronto's 140 neighborhoods' assesses the impact of several environmental, health, socioeconomic and demographic characteristics on lifespan. Authors Luckrezia Awuor and Stephanie Melles determined that premature mortality in Toronto neighborhoods was predicted by a combination of unhealthy environments and embedded socioeconomic imbalances.
In a study of commuting workers, the number of different types of food stores available near residences and commute routes -- but not near workplaces -- had a significant association with body mass index (BMI). Adriana Dornelles of Arizona State University, US presents these findings in the open access journal PLOS ONE on Aug. 7, 2019.
Urban sprawl has led to the creation of food deserts in metropolitan areas across the United States, according to a published study by a researcher at The University of Texas at Arlington. Shima Hamidi, director of UTA's Center for Transportation Equity, Decisions and Dollars, published 'Urban sprawl and the emergence of food deserts in the USA' in Urban Studies Journal.
Engineers designed a new system to help cool buildings in crowded metropolitan areas without consuming electricity, an important innovation as cities work to adapt to climate change. The system consists of an inexpensive polymer/aluminum film that's installed inside a box at the bottom of a specially designed solar 'shelter.' The film helps keep its surroundings cool by absorbing heat from the air inside the box and transmitting that energy into outer space.
Analysis shows that while national-level economic growth and social development -- including more women in government -- are associated with more abundant wildlife, growing human populations are linked to wildlife decline.
Scientists investigating the effect of air pollution on lung health, in an animal model, have concluded that even low levels of exposure can have a detrimental effect on the lungs. They say the results have implications for government agencies responsible for urban planning.
New University of Arizona research suggests the key to getting more people to use public greenspaces may be making access to them easier and safer.
