Tishaura Jones, the first female treasurer of St. Louis, set out to improve her city through good design. Through her own struggles dealing with the city’s bureaucracy she identified many problems with how information is presented, she noted she wasn’t the only one running into bad design. Jones decided to do something about it; the policies were there but nobody knew how to understand them since the information was presented in a Byzantine way. She has led St. Louis to alter how information gets communicated to its citizens.
As treasurer of St. Louis, she used two key design techniques to improve policy delivery and outcomes. First, she reached out to other cities that had prototyped and tested new, human-centered policies. Building on what other cities had learned allowed St. Louis to springboard forward instead of getting stuck reinventing wheels. Second, she brought together policy and processes, applying people-centered design to the rules that governed services and the delivery of them. By building connective tissue between policy, process, and people, Jones was able to built new trust in old institutions to deliver real change impacting residents’ lives.
Justin King, policy director of the family-centered social policy program at New America, where I did research, has spent his career working on issues at the intersection of children’s lives and government policies. “Tishaura and Jose before her are reinventing what’s possible inside government,” he says. “People see the state and municipal government, in a lot of cases, as a predator on them and their communities . . . [Their work] is against the tide. It is really positive and really innovative and really worth talking about.”
By watching an annual bicycle race researchers found evidence of climate change. The Liège–Bastogne–Liège one day race has been running for decades and filmed since at least the 1980s. Because the route covers much of the same ground every year some researchers figured that they could use it to witness how plants are reacting to our warming climate, so they watched a lot of races but watched the trees not the racers. This sort of research is really neat since it provides another way to visually analyze our planet and share that knowledge.
Co-author Lisa Van Langenhove sifted through more than 200 hours of television data of the race shot between 1981 and 2016. Though the route had changed over the years, the team selected 12 climbs and landmarks where they could pinpoint individual trees. They studied 46 trees in particular. Most of them were not native to the area and included magnolia, hawthorn and forsythia.
The researchers found that in the 1980s, there were virtually no leaves on trees. After 1990, however, many trees were already in full leaf.
The change was significant. When leaves begin to emerge on a tree branch, it’s referred to as flushing. The study found that between 2006 and 2016, 45 per cent of trees had begun to grow leaves. That’s compared to nearly zero in the 1980s.
I’m one of those people who suffer from motion sickness and I can confirm that it’s so unpleasant I avoid boats as much as possible. Thankfully the car company Citroën knows people like me exist and decided to help us out. Citroën has created bizarre-looking glasses playfully named SEETROËN to help alleviate motion sickness. Based on the promotional video it looks like the glasses are also meant to help people who want to read their mobiles while travelling too.
So how are these goofy glasses supposed to alleviate the problem? The frames feature something called Boarding Ring technology, developed by a company of the same name, which is marketing-talk for ‘they’re filled with liquids that are free to slosh around’. The Seetroën glasses have four liquid-filled rings that, thanks to gravity, simulate the angle and movements of the horizon so that the motions of the blue-dyed liquids seen by the wearer’s eyes match what their inner ear is detecting.
Thankfully, Citroën says, passengers don’t need to wear the Seetroën glasses for their entire trip. Once they put them on and stare at an unmoving object, like a smartphone or a book, it takes about 10 to 12 minutes for the brain to resolve its feeling of confusion and nausea.
Falling apart houses, patches of unused land, and generally neglected residential spaces can be found throughout American cities. These urban blights not only look ugly but cause societal problems as well since it’s a neglected space that nefarious activities can easily take place. Cities have found success in converting vacant lots into community garden spaces to address these concerns; however, in some cities there are too many vacant lots and not enough demand for more gardening space. Philadelphia found that just greening vacant lots by planting some sod and trees they’ve been able to improve neighbourhoods and help the city in other ways like local temperature cooling and water management.
The PHS LandCare program recognizes that while vacant lots in legacy cities greatly outnumber the organizations or individuals willing or able to turn them into gardens, vineyards, or parks, allowing those lots to remain derelict condemns their surroundings to continued blight. To address this, PHS developed an inexpensive, low-maintenance approach to vacant lots that involves only basic sodding, tree planting, and erection of simple split-rail fencing on the lot. Today, PHS, with support from the city of Philadelphia, has installed and maintains LandCare treatments on more than 7,000 vacant lots across the city.
Facing this problem, cities realized that their vacant land inventories offered an alternative. Instead of using the traditional method of channeling stormwater runoff into the sewers, the water could be channeled toward green spaces, where it could gradually filter through the ground and refill the aquifers under the city. Such a strategy would be far better environmentally and would also reduce the need for massive holding tanks and allow cities to comply with EPA requirements at lower cost. Philadelphia was the first city in the United States to turn the idea into a reality by developing a detailed plan and a 25-year implementation strategy, which was approved by the EPA in 2012.
The lush, dense, quality of rainforests instantly make one think of how beautiful and efficient they are at making fresh air (and thus suck up carbon). As a result of the obvious wonderfulness of rainforests we’ve done a lot of work to try to protect rainforests from destruction. We need to the same in our cities. In London, researchers used LIDAR technology to better understand how much carbon urban trees soak up. Trees in urban centres love to absorb that carbon! The proximity to carbon sources like automobiles make urban trees really effective at air-cleaning so much that they are comparable to rainforests.
Thank your local tree for making your air cleaner!
The UCL team used publicly available airborne lidar data collected by the UK Environment Agency, in conjunction with their ground measurements, to estimate biomass of all the 85,000 trees across Camden. These lidar measurements help to quantify the differences between urban and non-urban trees, allowing scientists to come up with a formula predicting the difference in size-to-mass ratio, and thus measuring the mass of urban trees more accurately.
The findings show that Camden has a median carbon density of around 50 tonnes of carbon per hectare (t/ha), rising to 380 t/ha in spots such as Hampstead Heath and Highgate Cemetery – that’s equivalent to values seen in temperate and tropical rainforests. Camden also has a high carbon density, compared to other cities in Europe and elsewhere. For example, Barcelona and Berlin have mean carbon densities of 7.3 and 11.2 t/ha respectively; major cities in the US have values of 7.7 t/ha and in China the equivalent figure is 21.3 t/ha.
