Walking Danger

Autumn brings color into nature. This is for some the bright side of life. However, the sun sets much earlier every day and many people begin to walk to school or work and back during the dark time of the day. Unfortunately, this entails an additional danger to those walking the cities as bad light conditions cause many accidents of pedestrians. The statistics provided by Destatis (2024) for Germany show a marked increase of walking accidents from September onwards and lasting throughout winter. Equip yourself with bright colors and reflectors to avoid being a walker in danger or a walking danger. On Sunday it is pretty safe to go for a stroll. City life is less stressful and professionals in a hurry usually take a rest on that day. The conclusion is to choose your track wisely in order to feel safe on weekdays.

Games over

All nice things eventually come to an end. So do the Paris 2024 Olympics and Paralympics.
The images have been impressive of both events and the millions of spectators give a good testimony in this respect. The cultural by-program of the Games was equally remarkable. The live performances of dancers not only on the opening and closing ceremonies attracted big audiences. Many well-known sites of Paris prepared their own events and inspired as well as entertained the visitors.
On the small stage in front of the “Marie de Paris”, the city hall (Image below), ballet performances (video) were staged to hint at the possibility to see more artistic performances throughout the year in Paris opera houses and other stages.
Showcasing many forms of cultural, inspiring and entertaining events gave a valuable additional flavour to the Paris Olympics. Many good reasons to come back and renew unique moments in Paris beyond 2024. Paris hotels will be more accessible again for moderate budgets and waiting times for entries should come down to normal levels as well. Back to a new normal for Paris. Well, maybe. The millions of spectators who followed the Games on television and social media might eventually decide to rank Paris higher in the “cities you have to go to at least once in your lifetime”.

Paris Trees

Preparing metropolitan cities like Paris for the heating up of the globe due to climate change is a huge task. As early as 2020 Paris started an ambitious greening program. 170.000 new trees by 2026 in a densely populated city is a steep challenge. With 114.000 trees planted by 2024 as the Olympic athletes and spectators gathered in Paris the city is right on track. The 2 parks “bois de Boulogne et bois de Vincennes” have jointly 25.000 new or renewed trees. The cemeteries, for example “Père Lachaise” has received new cooling trees as well. Most trees, however, were planted along the notoriously hot and overcrowded “périphérique” with 50.000. Only with the use of a Colbert-like planning exercise and rigorous implementation against even some initial resistance, it is possible to achieve this result and the ultimate objective. Visitors of the Olympic Games already experienced the differences during the summer of 2024. Detailed planning by means of a “Bilan par arrondissement” facilitates monitoring of progress. Publishing the information is part of the communication strategy to keep citizens informed and engaged in this silent transformation for the benefit of inhabitants and visitors.

Paris Experiment

The Olympic Games 2024 were prepared years ago. Already the application procedures to prepare “un dossier” has to bring in lots of ideas and imagination what is desirable and feasible. Paris opted for a celebration of sustainability in a city proud of its medieval heritage and the Haussmann tradition of radical transformations of a city with large boulevards and representative buildings. From the “Arc de Triomphe” the major axes of communication between “arrondissements” become visible. 100 years ago the city had already been transformed according to this master plan. At that time sanitation of a city meant different things than today. The invasion of inner cities by Diesel-driven cars made life unhealthy again. Now, the Olympics gave reasons to restrict cars and lorries passing the inner city and the great boulevards. More tourists need more space and shall keep a much better memory of how pleasant Paris was during the Olympic Games. This could be a game changer for urban development in general. The proportion of pedestrians versus cars has to be shifted in favor of the walking population for many reasons. Tourists will flock to the city, if the overall and shopping experiences are great. Back to the future sounds crazy, but it has an interesting flavor to it for urban renewal and residents as well. (Image Paris 2024-8, b/w color filter applied, enlarge to see vasque)

Paris Parks

There are many splendid parks in Paris. They all have an important function to cool the city in summer. Good for exercise and walking all year round as well. The latest addition is the “parc suspendu” between Gare de l’Est and Gare du Nord (Jardin Marielle-Franco).
Many travellers pass there from one station to the next. The creation of this space is rather tricky and avoids the building of yet another shopping mall for tourists. The cleaning of the park and the growing of the grapes are a challenge for those in charge.
This park is an interesting melting pot of very diverse social groups. The sportspersons and walkers confront “la misère du monde” of people entering to sleep rough in the park or attempt to do or deal drugs there. Paris is fighting back for its public spaces and devotes resources to these purposes.
The “Cru bourgeois” is also challenged in this area. Living together accepting the unresolved social problems and to confront them rather than to ignore them, this creates the “metropolitan experience”. Parks in and around Paris build on a great historic tradition. “Le Nôtre” stands for the creation of Parks that were copied across the world.
The cleaning up of Paris for the Olympic games 2024 is a tremendous effort. The swimming in the Seine (rather than singing in the rain) is probably the steepest challenge of all efforts, even if in retrospect the opening ceremony happened during heavy rain.
Parks need water, rainwater is best. Hence, the alimentation of parks from sources far away from them is part of urban and landscape planning.

Community Gardening

Gardening brings people together. Not only in the countryside, but also in the middle of cities. Brussels is a nice example of this. The city district called “forest” has a community gardening project that has an astonishing amount of followers. The results of the joint activity are visible from the the park nearby and in the far distance the tower of the “Palais de Justice” can still be seen. In years with above average amounts of rain the watering of the community garden is much less of a concern. Neighbors respect the initiative and even dogs are kept off the area. It is not graffitis or rubbish left behind that discourages the gardening enthusiasts there. Such projects can work even in the vicinity of less wealthy areas. Mixing different communities in inner cities is day-to-day experience. Gardening and the beauty of nature is there free to enjoy for everyone. The seeds, fruit and small young trees are then planted in other public spaces. This is a marvelous effort to stem the tide of delinquent behavior all too often spoiling the inner city environments. They might still be only a few, but the community gardeners have impact.

Back pain

Most people know some form of back pain. This is understandable as an ever increasing share of people work in seated positions and spend additional leisure time in a similar position (gaming). Recurrent back pain is a frequent diagnosis. An Australien study has found a rather simple remedy for the widespread pain. The WalkBack experiment succeeded to significantly reduce recurrent lower back pain in study participants. Individualized and progressive walking accompanied by an education program did the trick. Keep on walking and try to extend the range of the exercise. It’s amazing to witness how the human body adapts to being challenged. Learning about the mechanics at work like the release of own personal “pain killers” hormones helps to trust in your body’s positive response to each dose of the challenge to pain. Do not walk too quickly too far. Stretching is a must and not an option. Go for it. Modern technology (in any smartphone) supports your efforts with counting your steps and measuring distances. Keeping track of a “pain diary” might give you guidance not to overdo the exercise and pause activities. Join a group of friends or people who are like-minded and get adequate shoes and clothes to feel comfortable while walking and afterwards as well.

Bikenomics

There is a whole cluster of enterprises associated with bicycles. Selling a bike is only the first we might think of. Repair works are the most tricky part of bikenomics, a bit like bidenomics. In many cities during spring and summer it is even more difficult to get an appointment for bicycle repairs than for a doctor’s appointment, and that can be hard at times. Shortages of skilled technicians are pervasive in this sector. DIY for do it yourself is the best alternative. With the arrival of e-bikes and the digital connectivity the skill set has been enhanced recently as well. Insurance for bikes, lockers, helmets, airbag system or clothing including spectacles are part of the standard safety and security set of bicycle riders nowadays. Many, many job opportunities there and the willingness to pay for bicycles has steadily increased over the last years.

Berlin has just seen its 48th bicycle demonstration in 2024-6 on roads including 2 motorways with several ten thousands of participants. In a star like fashion multiple tracks met at the city center. The final meeting with stands and information was at the Deutsche Technik Museum with refreshments and repairs. The exhibition of cargo bikes and taxi bikes or “rickshaws” was another highlight. We need to rethink our mobility concepts and try to get the sharing to work more comfortably. For different purposes and activities you need a different bike. Ownership of each is no longer adequate as for example with aging alone your preferences for mobility with bikes also changes. Sharing is caring and this is also part of bikenomics.

Cars electrified

It is not only cars, but the whole automotive industry that got somehow electrified. The U.S. have imposed a 100% tax on electric cars produced in China recently. Europe is feeling the heat as well (compare Fressoz in Le Monde 31.5.2024). Production of cars is not a for fun activity. It is firmly embedded in our economic system which believes in profit maximization even at high environmental costs. Therefore, the production of cars follows the logic to build cars that generate the highest profits. Bigger cars yield bigger profits and this has been known for decades. Why should we expect our car producers to deviate from this logic. Investors push hard in this direction as well. Small e-cars generate small profits. This can only be economically valid if large numbers are produced. China’s home market has the market size and air pollution levels that make this a viable strategy also for the lower income people. If not sold in the US or Europe, the home market is able to absorb huge amounts of electrified cars. Downsizing of cars needs to happen particularly in inner cities. The implementation of this is not going to be easy and without resistance.

Silent Pandemic

There is a pandemic that is silently spreading across countries and continents. It only indirectly related to the Covid-19 pandemic. The medical journal “The Lancet Respiratory Health” (2024) has an editorial about the inequities of asthma as they develop over the life course. The development of asthma has pre-natal, genetic, environmental, life-style and socio-economic co-determinants. The study of respiratory disease, therefore, is a multi-factorial issue, which needs to disentangle the specific influences. Smoking as well as obesity have an impact on asthma, instantaneously or with delayed time effects of sometimes many years. Hence, it is important to take the whole life course into account, if we want to address the rising disease burden of asthma. Air pollution and heating-up of the planet are important drivers of the silent asthma pandemic across the globe. The social distribution of people working in “asthma- prone” work environments and/or living in highly polluted urban, suburban or rural areas near high frequency traffic is another latent factor causing huge costs to persons and society as a whole. Health inequity is growing over the life course. This is not easy to tackle as policy target as the onset of the disease has no single trigger, but rather a combination of influences that contribute in varying amounts to the evolution of respiratory diseases.
