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)

Green Olympics

Paris 2024 has won a medal for the Green Olympics. Sustainable building of Olympic sites is a crucial element in this struggle for saving resources. Just as important is the CO2 footprint of the transport within the city if you cannot prevent thousands of people from flying to the venues. Public transport in Paris used the occasion to improve its services considerably. The restrictions to cars driving around in the inner city also for security reasons made the Olympic experience for Paris a healthy walking experience for all. The view from the “Arc de Triomphe” during the Olympics in Paris is even more pleasant and relaxed as the noisy and polluting traffic is reduced to minimal levels. You were able to grasp the feeling what inner cities could be like if people were the overriding concern of cities rather than circulation of automotive vehicles. Redressing this balance in favor of people living, working and visiting is overdue and we all know this. The city of Paris used the occasion to demonstrate that another way or compromise is possible. This is also a way to write history and create unforgettable moments. Paris discusses already what to keep from the Olympics for longer. Maybe the vasque, maybe the cleaning crews. New Metro lines, of course. Why not the different traffic and mobility patterns? It’s well worth a lasting Green Olympic medal.

People’s Olympic

The Olympic games have an elite touch attached to them. The selection beforehand is though and during the games another selection has to take place. After all there are only 3 medals to be awarded per competition and the runners up receive much less attention. That’s what the Olympic fame is built upon. To get more people involved in the games Paris 2024. had started the running and arrival of the flame weeks before the game so that public attention and awareness that people are part of the game as well. As spectators participation is feasible but rather expensive and out of reach for many supporters or locals. Hence, criticism of this kind is as old as the Olympic idea. Paris 2024 has tried several ways to mitigate the selectivity. Even distribution of tickets for free to visit performances has been widely spread. Most people will watch on their couch even if you live nearby. Places in Roman “panem et circenses” games in amphitheaters were scarce as well and reserved for citizens. Paris has built a brand new train station and lines to the stadium and the Olympic village. ( Image below RER Terminal, Saint Denis) on the outskirts of Paris. This will serve after the Games for many years to come. Inclusion of people has many facets.

Olympic Celebrating

Paris 2024 gives lots of reasons to celebrate athletes and teams. France has already achieved a large number of medals and shops in Paris start to decorate their windows with their emotional expressions of various forms. Merchandising seems to work well and some shops add a personal touch to special heroes. Walking the marvelous streets of Paris from one monument to the next is a pleasure as the streets are surprisingly empty and many are closed for cars and lorries. Hence, walking in Paris is a rather healthy exercise at this special moment in time. It is a great way to welcome all nations to Paris and allow a rather stressless visit of the city and its tourist attractions. Riding bicycles and buses becomes a pleasure too as roads are rather empty and circulating around the city is much easier than at any time before and probably after as well. Thanks for the great experience and the welcoming atmosphere.

Park Le Nôtre

Landscapes and gardens maybe occasions of splendid design. Paper and pencil designs or oil on canvas have left us with great imaginations of gardens as well as parks. The garden designer Le Nôtre in France has left us unforgettable, fantastic landscapes that have been originally realized 300 years ago, but has still many people you are impressed when looking or walking in them. One of the earliest projects is to be admired in Meaux just next to the cathedral. The design of the “jardin Bossuet” is attributed to Le Nôtre who later designed the park in the “Chateaux Vaux-le-Vicomte”. These accomplishments earn him the invitation also to design the gardens of Versailles. As part of the Paris 2024 Olympics the whole world was able to watch some of the horse mounted competitions there. Architecture leaves us impressions over centuries. Gardens are the most natural part of this cultural heritage.

Meaux France

Olympic Village

The newly built Olympic Village in Seine Saint Denis consists of 82 buildings and offers 3000 appartements. With up-to-date cooling and heating technology from a nearby geothermal source the eco friendliness is assured as well. Inclusive accessibility allows for games for all and the needs of an aging society. The price level of renting apartments remains a difficult to solve issue as demand will exceed supply for years to come. Universal accessibility is a necessary precondition to host the Paralympic games also in 2024. Historic sites are notoriously difficult to adapt to aging societies and inclusive approaches. However, the adaptation takes a large step towards the realization of inclusiveness of extraordinary people. The care for environmental sustainability has been honored as well. The exhibition in the Museum of the city of Saint Denis at the outskirts of Paris demonstrates the significant size of the urban renewal project. The socioeconomic and environmental benefits are evident and will give a push towards this previously deprived suburb. A lot remains to be done but the new trajectory for urban development is already put on track. The oblivious factories and enterprises give way for urban renewal of housing for people with easy access to the Paris city centers as well. (Source of Image)

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.

Plastic wasted

The amount of plastic that is wasted exceeds our imagination. Even in the most distant islands we find remaining pieces of plastic from our careless consumption. The European Directive 2019/904 has set the limit on detached bottle tops to July 2024. The industry waited until the last few months to implement the old directive. Great that there is hope to find less detached plastic in oceans across the world in some years at least. The behavioral change to move beyond plastics everywhere in our nutrition delivery system is long overdue. We shall get used to bring our own bottles for a refill or other devices to reduce plastic waste further. The change begins with thinking about the topic and finding suitable reusable packaging solutions for yourself. Children learn in art projects about the importance and creativity potential to reuse otherwise wasted materials. Reduce and re-use can be turned into an own competence. Competence in sustainability has been neglected for decades in school curricula, despite its importance for our own health and survival.

Olympic Games 1924

100 years after the Olympic games were held in Paris, they will take place there again. Each time for the Olympic games new locations (Colombe) were built. For the 1924 games for example the first 50m swimming pool was built (Stade nautique des Tourelles, Porte des Lilas, Paris 20th), but a new one will host the 2024 competitions. However, the old pool will still serve in 2024 for the preparation of the competitions. The successors of Johnny Weissmuller (5 gold medals in swimming 1924) and star in many Hollywood films, the access to the stadium has become much more secured these days. In fact, security has turned into a crucial issue to host the “peaceful games”. In 1924 Germany was still not allowed to participate in the Olympic Games in Paris as the security of participants could not be guaranteed. Some competitions at the time turned rather violent as the example of the rugby competition, in which the converted American football team as rugby players had beaten the Fench rugby team.
The idea of alternative games has also been around for decades. There were already in the 1920s international competitions of worker associations (for example Frankfurt 1925) and the Olympic idea had to defend itself against the accusation of a Western countries’ domination. The set of disciplines in the competitions is always up for discussion and negotiations. We shall see interesting new additions in 2024, like break dance, to broaden the understanding of Olympic disciplines.
Even 100 years after Pierre de Coubertin steered the modern Olympic games, the idea is to bring more to the games than “Faster, higher, stronger”, notably to be together. To be together in a peaceful way remains the biggest challenge for humanity. The inclusive turn is, however, a challenge to host the games, particularly to host paralympic games in inner cities that have abundant barriers of access for impaired persons. Inclusiveness for many countries is another challenge that goes beyond the simple participation in the games, but consists in training facilities and equipment for many disciplines.

Greening Brussels

We tend to believe that inner cities have lost the fight against traffic jams and climate change. However, the number of projects that stem the tide is growing and some have gained visibility beyond their immediate neighborhood. This is the case of an urban planning project in Brussels that has taken back space from urban traffic to the citizens living there. Planting new trees and a gardening space reserved for flowers changed the street into a pleasant environment where people meet and greet again rather than hold their breath and disappear as quickly as possible. Parking of cars has been reduced on the street and instead bicycle parking has become a hint towards more sustainable mobility in inner cities. Walking the city, staying and shopping nearby will allow behavioral change for healthier lifestyles. It needs a lot of persuasion to accomplish this impact and years of reaching majorities for such projects and the ability to raise sufficient resources to implement them. The additional challenge is the need to take care of the green spaces that only works with the support of neighborhoods assisting in the care and protection of the urban lungs. As the awareness to act against inner city heat and pollution increases the number of persons willing to act and devote resources as well as time for such projects increases as well. It is a long way to improve inner city health again, but these signs of exemplary projects will convince many other people that urban renewal can work to the benefit of people.

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.

Beggar thy neighbour

Modern economics has developed the concept of so-called external effects. The oldest version of it might also be referred to as “beggar thy neighbour”, as it was coined by Adam Smith the founder of classical economics. This describes an economic policy which does not care to make your neighbours worse off by enriching yourself. Applied to environmental economics or to regions, cantons or neighboring countries, this means a ruthless pursuing of investments, which are known to shuffle a large part of the costs onto other regions through damages, might be pursued nevertheless. This might be a valid hypothesis to test how the investment in skiing at high altitudes, increases the risks of flooding at the lower altitudes of rivers or valleys. There is scope for a redistribution of wealth from one region to another. The poor neighbor, however, is in a rather weak position to claim compensation as the link between the 2 events is hard to establish scientifically and mediated by an abstract form of overall climate change. The recent example from Switzerland adds to an increasing number of natural disasters, which are in fact man-made following a beggar thy neighbor rationale. (Image newspaper reading room in Stabi Berlin with NZZ from 2024-6-24).

Nutrition Policy

The evidence on nutrition policies has accumulated a series of policy recommendations based on the best available evidence. The German Institute of Human Nutrition has presented these results repeatedly not only to the scientific community, but also to the interested public at the Science Week or the Long Night of Science. Their leaflet on the tools to improve our human nutrition in market economies highlights “nutrition competence” as a key component of a broad strategy to improve our food and subsequently health. Nutrition goes beyond the biological ingredients of food to include basic understandings of human metabolism including the times and timing of meals. This competence has to be transmitted to preschoolers, pupils as well as adults to stem the waves of obesity (ARTE Docu). Learning how to manage your own nutrition is a crucial competence to strive and survive. In schools it can have substantial impacts on performance and inequality of opportunities as well.

The science-based policy recommendations propose to alter the structure of costs, for example via tax reductions, in favor of healthy food. Plain water should be substantially cheaper than sweet beverages or alcoholic drinks. Nuts and proteins from vegetables fall in the same category as plain water. It is in the longer term interest of all of us that schools, canteens at work places or homes for the elderly offer also healthy nutrition at least as a daily option. More sustainability in food production is last, but not least part of nutrition policies. A lot to chew on to improve nutrition.

Food Future

What do we have for dinner today, tomorrow or in 10 years from today? Research Institutes presented some of their insights based on solid evidence in the open door event in Berlin. The 5 years of the project “food4future” are over and my glance through some of the results suggests that we shall have many more proteins, most from vegetable sources, on our plates. The arguments for improved sustainability are rather compelling. The taste of these products that currently have higher amounts of bitter taste might be solved. Similarly sea food beyond fish like halophyte will enter our diet. The salty taste can be incorporated in meals in which we add salt or other spices anyway. These elements might make it possible to feed the 8 billion people on our planet. We probably also need to include protein rich insects in the meal plans of the still growing human species. It appears like a rather long shot into the future of nutrition, but if we do not think ahead and start the change in our mindsets we shall be badly prepared for the future and more people will decide to seek food in other places of the earth rather than stay hungry. It also helps us to refocus our priorities in nutrition and aim for a better balance of the pleasures of eating and sustainability. The issue of food for future generations starts with food for thought in the abundantly nourished Northern parts of the planet.

LED light

For decades now, we have the LED light technology around us. In many instances we do no longer realize the presence of light emission devices (LEDs) for example in our television screens or in road lighting. However, this still is an exciting field of electrical engineering and the replacement of gas lighting as well as other electrical devices with higher energy consumption are high on the agenda for sustainable lighting. There are important health and security aspects related to lighting (sleep and road traffic).
In Berlin the demonstration and test area for innovative LED lighting is also an open-air museum which can be experienced throughout the year. The party-goers and club visitors might best know the demonstration street as part of the “Deutsches Technik Museum” The energy saving potential of LEDs use in street lighting is substantial and should interest most rural and city councils. The demonstration of the differential effects of targeted lighting and broad illumination based on the same technology is impressive. Of course, the design aspect of LED-technology with the colourful potentials are of interest beyond the technical aspects to replace for example gas lighting. There is much more to lighting than just opening your eyes in the morning. (Image FG Lichttechnik TU Berlin)

Aussensicht Innensicht

Die Sicht vom Skulpturengarten der Neuen Nationalgalerie auf die laufende Ausstellung „Zerreissprobe…“ erlaubt einen tiefen historischen Einblick in die 1980er Jahre. Die Sammlung von Postern des Künstlers Klaus Staeck zeigen die bewegenden Themen der achtziger Jahre. Frauenrechte, Umweltschutz, Sicherheit sowie Medienwirtschaft. 40 Jahre später beschäftigen uns weiterhin, Lösungen für die plakatierten Themen zu finden. Images können Themen so zuspitzen, dass Anklagen daraus werden. Texte sind im Vergleich zu der Eindrücklichkeit der Bilder ein vergleichsweise stumpfes Schwert. Es ist aber gerade die Verbindung von Bild und Text, die Eindrücke verstärkt. „Meme“ Creators sind ein standard tool das die Kommerzialisierung und die Promotion weiter befördert haben. Kunstformen hatten diesen Trend bereits vorweggenommen.

Forecasting floods

As floods as becoming more frequent and more severe forecasting of such events is crucial. The recent example in Bavaria (Germany) of the Danube river (2nd longest in Europe) has demonstrated the role of forecasting to spur adequate behavior of people living in areas at risk of flooding. With the weather forecast announcing lots of rain for a large area the forecasting of floods needs to follow closely these trends. It is not only a question of expectations, but an issue of adaptive expectations for people to adopt appropriate precautions. In retrospect the early forecasts turned out to be fairly accurate in terms of the peak of flooding to be expected in June 2024. The Bavarian “Hochwassernachrichtendienst” (no joke, one word) forecasted on the 2nd of June about 7.50 as the peak to be reached in 2 days in the city of Kelheim. This was beyond the usual 4 warning levels based on an escalation scale. The forecast was beyond the frequent flooding levels established in the last decades. People and emergency services would have to adapt their expectations accordingly. Renewing forecasts is essential to guide people and services in their efforts to deal with emergencies and repair damages as flood levels recede. Management of crises critically depends on forecasting even if they are obviously prone to error margins which should usually be reported as well just like in weather forecasts. Adaptive expectations are key in combination with forecasts to ensure survival.

Marketing bicycles

The marketing of bicycles has changed considerably over the course of history. Today’s narrative is more about the eco friendly impact of it. Historically the freedom aspect of free movement and emancipation of women was at the forefront. The collection of images in poster formats presented at the DTM in Berlin is impressive. The focus on women on bicycles is quite surprising for this early time around 1900. Few of the companies from the early days have survived until today. Bicycles are still fascinating children and adults today. The experience of a fragile equilibrium, your own strength and weakness in muscle power, cardiac or pulmonary strength is always challenging. It is you who is in control of speed and direction. This should be easy to sell to the masses, and it was and still is. “Bikenomics” is here to stay. Artists had the same impression and created a whole universe of promises for riders of bicycles. The long run health benefits were not even known at the time, but it was unthinkable that humans would spend most hours sitting in offices, cars and on their couches. The biking story needs to be retold to encourage people to take up the emancipating storyline again. Get on your bike again!

DTM Berlin 2024-6

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.

Law Nature

There exists a rather complicated relationship between law and nature. It is part of constitutional law to check whether nature figures at all in a state’s constitution as part of the fundamental legal principles. On a global scale the nations or people living in the closest relationship with nature most often do not have written constitutions. In the same vein, animals or biodiversity do not figure in most constitutional documents (nice project to substantiate this claim). The philosophy of law has line of literature devoted to “Naturrecht” which is more concerned with human beings and their differentiation than the millions of other species.
Administrative law is probably the domain with most of the legal judgements with relevance to nature or the environment as for example any larger scale construction is either land, water, air or biodiversity grabbing. Rights and limits need to be defined precisely. In this field the role of law as “appeasement” is widely applied. However, this is more complicated in cases when a whole population of an island in the ocean is threatened to disappear due to the rise of the sea level like in the case of the Torres Strait Islands, next to and part of Australia.
The UN Human Rights Committee (UN-HRCee) in Geneva has made a decision on the claim of these people to have rights that the nature of the islands as low-lying islands is threatened by disrespect of their fundamental rights of existence and survival. The claim has been received by the court, but the court deems that the threat to their culture and survival is not imminent. In practice, therefore, the sword of law is rather weak and time until the disaster is used as a right to continue the usual economic exploitation of earth as before despite the deferred consequences for the planet in a rather unequal way.

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.

Portable Grundgesetz

Celebrating democracy in Germany is rare. We take it for granted that democracy persists, as most of us have not experienced it otherwise in Germany. This is grossly mistaken as the opinion polls show repeatedly in recent years. Therefore, it is welcome to find the “Portable Grundgesetz” at the “Demokratiefest” in Berlin and Bonn at the event to celebrate 75 years of democracy in West Germany and 35 years in East Germany.
The century-old tradition to produce miniature books has been revived and the miniature books have been widely distributed at the event. A side effect consists in the eco-friendliness of this version, which saves a lot of paper. It is fun also fun to turn pages rapidly and discover some paragraphs which we would not have read otherwise. “Daumenkino” is the German word for versions that contain many images. Maybe next time, an illustrated and/or animated version of the Grundgesetz could encourage youth to celebrate using the texts, §s and images to discover the fundamentals of our constitution.
325 years ago, Weigel the Elder has illustrated, edited and published such a tiny edition of the Bible. It is currently exposed in the treasure museum at the “Kulturwerk” in the “Stabi Ost” in Berlin. “Back to the Future”, lots of ideas we get by taking archives seriously. By chance inspiration is undervalued. Search algorithms have a hard time to replace this in an effective way so far.

Competence Nature

Nature can be approached without competence. Emotional attachment is fine. If we delve deeper into the issue, we realize that a lot of processes that have evolved over years or even centuries are hard to study. The learning about nature is manifold and many scientific disciplines deal with nature in the broad sense of the word.
Today the study of nature is scattered across so many disciplines that an overall view of the field seems hard to achieve. This creates a problem to teach a competence to deal with topics around nature. Water, air, species, soil, climate or reproduction are all topics in which we have to make far-reaching individual and collective choices. This requires adequate competences to allow judgments about opportunities and risks involved.
For more than 100 years now we have researched education systems and processes, but the competences to talk and explain basic processes in nature are still scarce. Classification systems are a static way to sort nature into categories. Processes of evolution and development have more or less human input.
We all gain if we keep an eye on education and learning processes that have been applied years ago. The field of the history of education provides clues about some forgotten approaches. Learning about nature and how to acquire competence in the field has been an issue in this field for at least 100 years. It is time to test some of these approaches again to see what went wrong in learning about nature. Man-made climate change is only at the end of a causal chain of things and people moving in the wrong direction. We probably have to press the reset button and start from scratch with the learning and the tracing of wrong decisions. Maybe, the start is the appreciation of a splendid bouquet of flowers. Want to know more? Try to grow and assemble them yourself.

Competence Gardening

Primary Schools in Berlin have the possibility to participate in the “Gartenarbeitsschule”, the school with learning goal of gardening. It is an interesting option to go out into the real world and deal with nature, sustainability, consumption, climate and many other topics. Voltaire could complement the curriculum in philosophy with his biographical links to gardening. The access to the fields is easy next to one of the central train stations and a larger urban reforestation project as just one example of the 15 overall in Berlin in 2024. (Südkreuz, Südgelände). Hands-on experience of gardening can address multiple forms of problem-solving competencies. Beyond the use of AI, a major advantage is the possibility to train collaborative problem-solving. Beyond the multifactorial approach in determining what to plant, the organization of the implementation and individual contributions towards the realization, all these elements are learning goals. The scope of learning qualifies gardening for learning well beyond primary school as well. It is a nice example of lifelong and lifewide learning even a hundred years after their wider applications in Berlin.

Killing me softly

The problem with pollution is, it is killing you softly from inside. It is almost impossible to escape air pollution as it is pervasive in cities, but also in the countryside where you do not expect it that much. This is the result of the study by Kuzma et al. (2024) published in “The Lancet Regional Health Europe”. Based on a data set of 8 million persons from Eastern Poland the effects of air pollution on myocardial infarction incidence was analysed. The use of the “European Union’s Earth Observation Programme” contributed data on air pollutants like PMs, BaP (benzo(a)pyrene), SO2 and NO2 concentrations. The multi-level data of 5 voivodeships, 101 counties, and 709 communities in Poland allows to differentiate the effects of damage to the heart tissue on cardiovascular disease. The other well-known factors are arterial hypertension, diabetes, obesity, chronic kidney disease, hyperlipidaemia, and smoking as most of us know already. The effects of  BaP (benzo(a)pyrene) is shown for rural areas despite the lower observed traffic density in these areas. The killing occurs softly from within our bodies by just breathing in and out, and in and out continuously. The disease burden in these regions is observed with “recorded 63,154 hospitalizations and 5921 in-hospital deaths (9.4%) due to STEMI; and 76,543 hospitalizations and 4079 (5%) in-hospital deaths due to NSTEMI”. In short, the need to reduce air pollution further is an urgent demand that saves lives eventually.

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.

Infinite Landscapes

The “Alte Nationalgalerie” celebrates the 250th birthday of Caspar David Friedrich in Berlin. With a considerable effort to unite in one exhibition many paintings and drawings that stem from other collections of public and private origins. This particularly remarkable as a section of the exhibition is devoted to paintings that were intended originally to be seen next to each other (compare catalogue p. 233). Comparing 2 images from the same painter evolve into a narrative. This raises curiosity as in some instances the 2 paintings do not treat the same subject. Your very own interpretations and associations will make for an individual journey through the sheer endless spaces. The exhibition allows to grasp some of the many questions posed by the period of enlightenment not only in Germany. After “God is dead” what will happen? How is mankind defined? What is its relationship to nature? Are we just left alone or what comes after individualism? Even for painters, much like scientists, it is just as important to pose the right questions. Leaving the exhibition with more questions than answers will put you in the “Berlin state of mind” of 200 years ago. Greiswald, Dresden, Rügen and Copenhagen as well as nearby mountains were influential locations and landscapes for Caspar David Friedrich. Berlin 1906 „Jahrhundert Ausstellung“ made him famous again, despite decades of being forgotten. Yet another question to ponder and wonder about. An additional merit of the exhibition is the section on painting techniques and the use of his sketches and drawings for the preparation of the oil paintings. The final riddle to be solved is the price differential between the German and English version of the catalog in the bookshop next to the usual merchandising props.

Barbie Chemical

Chemistry is sometimes perceived to be uninteresting, but only until you realize it might be beneficial to know more about some underlying chemical processes. The Royal Society of Chemistry has finally found a topic in chemistry to give chemistry a popular push. The Barbie hype is far from over as we all learned in the recent past. Now conservationists have found a topic with chemical processes involved to demonstrate the usefulness of chemistry knowledge for the conservation of your treasures or collections of plastic dolls or puppets in general. Most plastics PVC was not intended to last, but the deteriorated forms have a long lasting effect in form of PVAS or microplastics. So aging research has reached popular concerns like the aging of Barbie, who is believed to be “forever young”.

Hannover Fair

The annual science fair at Hannover is a kind of a show of things to touch and of those things that come to the public market in the near future. Most of the annual hype is about potentials of production. Rationalization, using few resources or innovative solutions of digitization are high on the agenda. Create your digital twin, save energy, make production more safe or cyber secured.
Robotics is another reason to visit the fair. Some 7 years ago I had my Sputnik experience there. The robotics company KUKA had demonstrated live the that assembling a car from pre-manufactured components takes just 10 minutes for the robots. Shortly afterwards the whole company was bought by Chinese investors. Roughly 5 years later we are swamped by cars from China. It was not that difficult to predict this at that time. Okay, we need to focus on more value added production and take our workforces (not only) in Europe along on the way. Reclaiming well-paid, unionized jobs in manufacturing, as Joe Biden does, will not be an easy task. Robots and their programming is expensive, but skilled workers, too. Hence, the solution is likely to be robot-assisted manufacturing as a kind of hybrid solution for cost-effective production systems.
Following the proceedings of the 2024 fair we are astonished to realize that visiting the fair is still a rather “physical exercise” walking through the halls. After the Covid-19 shock we expected a lot more “online content”. Instead we keep referring to webpages and newletters rather than virtual visits and tours. The preparation of the visit in advance remains a laborious adventure. However, the in-person networking activities in the industry are largely advanced by ease of exchanging virtual business cards and the “FEMWORX” activities.
This year’s Sputnik moment at Hannover is probably most likely related to the pervasive applications of AI across all areas of the industry and along the whole supply chain. Repairing and recycling have become mainstream activities (www.festo.com). Robotics for learning purposes can also be found to get you started with automating boring household tasks (www.igus.eu).
Visiting Hannover in person still involves lengthy road travel or expensive public transport (DB with ICE). Autonomous driving and ride sharing solutions might be a worthwhile topic for next year’s fair. Last year I thought we would meet in the “metaverse fair” rather than in Hannover 2024. Be prepared for another Sputnik moment next year, maybe.
