On the impact of newer buildings on urban air pollution

2024-10-25T17:47:00-04:00

In hermetically sealed buildings, less fresh air gets in. [...] Eventually, this polluted indoor air – which is making more than a third of the planet sick – is expelled into the surrounding environment. This raises the question of how buildings pollute the air around them, what pollutants they produce, and whether this expelled air is sufficiently diluted once outdoors.

As the article mentions, the World Health Organization had previously pointed to a "lack of monitoring of air pollution levels, sources and consequences on public health" as a present danger for cities.

To fix it, authors César Martín-Gómez and Arturo H. Ariño of the Universidad de Navarra say: "A detailed understanding of how buildings contribute to pollution in cities is essential. This will give public authorities, decision-makers and managers the tools to establish strategies to, for example, minimise pollution through devices similar to the catalytic converters required on all combustion-powered vehicles. Eventually, we may even be able to recover useful components of domestic air, such as waste methane, which could be redirected to energy generation."

Noise-disrupting fountains? Belgian cities are leading the world in anti-noise pollution urban strategy

2023-11-10T13:26:00-05:00

Noise pollution often underestimated but significantly impacting our lives, has become a pressing concern in major cities worldwide. From the bustling streets of Brussels to the vibrant ambience of Paris, urban dwellers are increasingly raising their voices against incessant noise.

Exposure to noise pollution above an annual average of 53 decibels has been shown to shorten lifespans for city dwellers. Brussels, where 70% of residents are at-risk, has begun experimenting with pleasing “soundscapes” among other, more practical interventions that include lower speed limits, added greenways, and pedestrianization strategies. Antwerp is also planning to test out a new “noise-disrupting fountains” concept this spring. Ghent, finally, is attempting to limit maximum facade noise to 65 decibels using a combination of traffic reduction and improvements to road surfaces.

Planting trees could lead to fewer heat-related deaths in urban areas, according to a new study

2023-02-03T17:32:00-05:00

A new scientific study has shown the positive correlations between public health and tree planting in urban areas.

In a report published recently by The Lancet medical science journal, a team of European researchers shared data on mortality rates in 93 cities in the summer of 2015 that showed how premature deaths caused by urban heat islands can be mitigated through increased greening strategies.

The study found 6,700 premature deaths in that period related to the phenomenon. One-third of those deaths, according to the authors, could have been prevented by adding 30% more trees in the urban environments of each city. The data supports established notions that particularly low-income communities can benefit from resiliency measures, adding to a growing chorus of scholarship at a time when climate change is becoming a moribund issue for cities worldwide at an accelerated pace.

Loneliness is on the rise throughout the world's cities

2016-04-12T15:13:00-04:00

”...it might be that loneliness is often due to circumstance. The thing with cities is we are absolutely surrounded by people...We can see other people living richer, more populated lives than our own. At the same time, we can feel very exposed … there are lots of eyes on everyone. That is why the loneliness of the city has a particularly distinct tang to it. Loneliness, however, is often like bad weather, “it passes through our lives”.

Should the children of Flint be resettled?

2016-02-18T16:59:00-05:00

Given the threat of ongoing lead exposure and the community’s well-founded mistrust of government, should families be offered at least temporary resettlement while upgrades, repairs and enhancements are made to Flint’s badly contaminated water infrastructure? I ask this fully aware of how unprecedented and complex such a policy would be. After all, some 9,000 young children may have been exposed to contaminated water.
