Time Horizon

For ages human time horizons have worked as a succession of generations. With substantial population aging we have many more families where we find 4 generations alive at the same time. In nature and with respect to biodiversity the sequences of renewable have not changed much. Old trees that have been cut will take another 100 years to grow old again. Wild fires or human negligence risk big in this respect. Forests take several human generations to grow and thrive. Diversity is key there as well as many fast growing monocultures have increased risks in case of fires caused by global warming. Annual inspection of a forest that suffered a severe drought and fires is still looking dismal compared to before. (Foret de Senart, France 2025).

Design skills

The is a huge B2C or C2B market in connection with home design and adaptations. Nowadays people are inspired by instagram, pinterest, YouTube and TikTok. Additionally, many play around with Apps to create their own images of how they would like to arrange or rearrange their home. Some have taken first steps to include measurements of their home in the design. The compatibility with professional software of the construction sector, however, is a drawback that delays or leads people to go to enterprises that take into account the prior efforts of young lay designers. It is a little bit like an own contribution in home building quite popular among new home builders to alleviate the upfront cash needed for first home acquisition. The younger generation could offer some of their “digital native” skills to bridge the gap in construction and home design. Of course, reworking and precise measurements on the location will still be required as construction has a lot of legal liability issues involved. Cooperation is a form of burden sharing to advance faster and/or with lower costs.

La défense Végétale

Greening a metal and concrete block and buildings is a big challenge. The logic of unrealistic growth and big business has left liabilities for future generations. More vegetation in inner cities is part of our responsibility towards future generations. Therefore, urban planning has started in Paris to get rid of concrete walls and floors.

Eventually the district might have a more human touch which attracts citizens and new businesses and services. The adaptation of the infrastructure to facilitate mobility with bicycles and secured pedestrian paths has started but will take a lot of time before people adopt again these more healthy modes of transport. The big boulevards reserved for polluting transport is no longer adequate in combination with residential living spaces.

It will take a change of a whole generation to accomplish such a fundamental change. The reduced demand for office space due to more employees choosing to work from home contributes to such a change as well. Many other cities go ahead with similar changes (Copenhagen, Berlin). In combination with the „All electric society“ there are fundamental changes at work which will make inner cities more attractive again. Ease of clean transportation and other infrastructure for urban lifestyles ensures that cities remain strong points of attraction. They keep pulling people from nearby and far away towards them, if we like it or not.

La Défense reframed

  1. The whole new business area „La Défense“ was a huge investment project with international speculators highly motivated to reap the benefits of a business location just next to Paris, which at best would even feel a little bit like being „intra muros“. However, being at La Défense you see „L’Arc de triomphe“ only quite far away and you don’t really get the impression that you are in Paris. The high rising buildings around there originally gave god reasons for expensive office space. Few residents spaces made the area uncomfortable in the evenings after office hours. After 2025 most office spaces no longer are attractive for businesses and lack behind environmental standards of the 2020s.  Many projects attempt to renovate the former office space into residential buildings with a considerable loss in the value of previous office space. For people working in the multiple shopping centers there this might be a feasible option if the rent is not excessively high. Students in transit through Paris might find this attractive as well. Families, however lack an adequate infrastructure as this area was built for an outdated business center and business model where families were believed to obstruct business efficiency. As the project developers have written off their investments over 25 years society can clean up the remaining space and repair. It will be another medium term project to re-create a convivial environment and community there as before the overriding device was make money there and run to a more human and diverse space.

More eCooking

Cooking powered by electricity rather than fossil fuels like gas is an efficient and smart solution. Through the daily cooking activities over the course of a year the savings due to eCooking add up quite a bit. Even compared to an ordinary electric stove the eCooking by induction technology saves almost an additional 10+ percentage of energy as you heat the pot or pan directly rather than an in-between metallic element, which stores heat even after you have switched it off already for a while. In private kitchens the induction option is straightforward. In professional settings the change to induction eCooking needs careful planning. The health aspect of no burnt gas emissions in the kitchen is, however, a strong argument in favor of eCooking as well.
If we apply this logic to low-income countries and cooking in schools or other institutions as well as companies, the environmental and economic benefits add up quickly. In rural areas where no electricity grid is available or stable enough, the decentralized provision of electricity through for example solar energy creates a cost-effective alternative. In urban areas with high levels of various kinds of pollution the “clean” alternative could make a considerable difference as well.
The eCooking evidence is another pillar of the “all electric society” of the 21st century.

Digital Visions

Urban planning has been digitalized for a long time. 3D modeling of places and buildings including their interiors are state of the art. As urbanization is also about investment, speculation and anticipation, digital imaging has entered the public spheres in form of cover up of building sites behind fences and in form of large digital prints for information, curiosity and advertising purposes. The inner cities are frequently an avantgarde and microcosm of societal developments. Some dream of full or total flexibility for office spaces (see image below), others experience the inner cities as the spotlight of inequality in society. The best paid executives are catered for by the worst paid delivery personnel. The photographers of the Landesarchiv Berlin, Grönboldt and Wunstorf, brought together a documentary exhibition entitled „Pixel aus Beton“, pixel made of concrete.

With a bird‘s eye view they reveal past, present and future details of how Berlin is experienced and envisioned by investors, architects and people living through the seemingly endless construction going on in the city. The keywords list as part of the exhibition creates a link to scientific literature and to the TU Center for Metropolitan Studies. Photography and even more so digital photography offers a social science perspective to the digital images exhibited. Cities are data spinning areas and a formidable place for digital visuals and visions.

Blue Sky

In the period of romanticism the associations with a blue sky were very different from today. Getting out into the sun was a kind of privilege for the “leisure class”, of people who could afford to enjoy time outside for boating, walking or other pleasures. In our technology-driven 21st century the associations with Blue Sky are more like a technically enhanced view through for example “Windows” at the news and opinion platform or “Bluesky”.
Several scientific websites that report data on blue skies and air quality more generally across the world report indicators like ozone values O3, sun intensity, micro particles 2.5µm and 10µm, Nitrogen Dioxid NO2 to name the mostly quoted indicators. Hence, just enjoying the blue sky outside isn’t the same as it was before. People working outside in the sun or at times of a blue sky but with high air pollution levels are incurring severe medium-term health risks. The Ozon layers at very high altitudes protect our skin and eyes against high UV-radiation, but O3 on the ground is tough for eyes and lungs.
Technology has come with many blessings, but the negative effects on a global scale become also more evident. Getting used to a particular lifestyle, which produces lots of emissions of aggressive fine particles will make it more difficult to just simply enjoy a blue sky.
In consideration of all these background data with regional variations, we surely need an AI-system which we can ask for advice, whether we should go outside and enjoy the blue sky with or without respiratory mask.
Romanticism has led us all the way to Californication and dangerous enshittification of the air that surrounds us. Youth and the next generations will have very different associations with Blue Sky than we have the chance to, at least, have had.

Greening Interiors

The greening of facades of houses is an old tradition in many western countries. The outside of a home then changes colors with seasons. The home for insects and birds feeding on them makes a small contribution to biodiversity as well. Greening interiors is a more rare instance. Of course flowers and plants can contribute a lot, but there is yet more scope to green entire walls inside your home or office.
Moss has advantages to add humidity to the air. You might like the acoustic effect as well in busy environments. Taking care of moss is not easy. Professional assistance (Link) or renting options might be a good option for office buildings. The wellness enhancing effects are also interesting for some people who susceptible to the calming effects of a more natural environment. It is a matter of care and respect for air quality that is reflected in the design using green interiors.
Circularity is another advantage of the materials. We can so a lot for biodiversity if we really wanted to even in urban spaces. Global warming will force us to think more and more, and sooner than later to make use of such innovative solutions. For the time being they remain a luxury option. For the wealthy, greening interiors is easy, it much less an option for restricted budgets and people who are obliged to focus on short-term survival. However, we have to get started with the greening of our planet again, any way.

January Spring

The early signs of spring in Europe usually show up in March. The monthly data from the Copernicus Climate Change Service (C3S) show that „average temperature over European land for January 2025 was 1.80°C, 2.51°C above the 1991-2020 average for January,“ (Link). The warming throughout January has several consequences. Vegetation starts into spring earlier. This means that people with allergies of early flowering suffer earlier during a year. Winter rest in animal lives will be shorter. The risks of droughts in some regions combined with floods in other regions is increased as well. Rockslides in the Alps and flooding in Italy and the Baltic states add to the costs of climate change. 

Western Europe, witnessed a relatively „dry January“, even for those who kept drinking alcohol throughout the month. Heating and heating costs came down a bit and friends of gardening were surprised by some early showings of flowers of spring even in Paris neighborhoods (image below) as early as the first few days in February 2025! Strange new world. It all seems to happen a bit faster than most scientists expected. Time for adaptive behavior is shortened as well.

United by travel

The economic rationale of profit maximization privileges the construction and management of profitable connections. For train transportation this has spurred over decades the construction of new train lines between metropolitan cities or regions. Whereas connections between Paris and Brussels are abundant and expensive from central stations those living somewhere in between the 2 cities, for example in Mons, have had little chance of access to reasonably priced and fast train connections. This neglect of the in between cities is slowly changing. Sufficiently fast and reasonably priced connections allow Europe to grow together also at the margins. Public transport as alternative to car traffic across borders for „in-between cities“ will bridge the gap between the ease of travel between metropolitan an more remote areas. There is economic growth to be reaped as connected infrastructures allow for economic as well as social mobility and joint development. This is the real European challenge ahead of us and not the numerous summits without tangible results for rural and urban populations beyond metropolitan regions. For regions spanning countries, some will be finally reunited by better public transport a kind of ecological unification.
