Gardening Evolution

Researchers continue to study the impact of gardening on biodiversity and survival of insects. The study published by Tscharntke, Batáry and Vidal (2026) points our attention to the importance of areas in our gardens that are allowed to grow without mowing for several years. In many traditional gardening projects even in the 21st century, we observe a cut of grass-shoots in fairly regular time intervals, once a months for example. An English style lawn will be cut very short even more often than this. If we want to allow for an evolution of gardening and regaining biodiversity, we shall have to reserve substantial areas of a garden to allow grass-shoots to grow over several years (!). Such an evolution might be perceived in 2026 a bit like a revolution in gardening. Untidy spots are a response to “the need for unmown long-term refuges, protecting intact grass shoots for persistent insect populations” (Tscharntke et al. , 2026). The tree “Cercis siliquastrum” (Judas-tree) in the “Jardin des Plantes” in Paris dates back to 1785 and shows the impressive strength of nature to outlast changing gardening fashions even in a hotspot of gardening culture, history and evolution. Grass-shoots below might be allowed to last a couple of years as well.

Birds nutrition

The winter diet for birds is less varied than during the other seasons. Human assistance seems to be appreciated as well even if food supply in inner cities appears to be abundant with huge amounts of wasted food in streets ans backyards. The different diets of different species are not easy to cater for. It is a two way learning and adaptation process. With a narrower range of birds feeding in cities, the task is easier than it used to be. Bringing back more diversity of birds in general starts with offering different nutrients as well. A long way to go.

Timeless Nature

The beauty of butterflies has fascinated thousands of generations. It is the boomers’ generation that has increased the risks that future generations will have difficulties to enjoy the simple beauty of nature in their gardens or parks. Preservation of biodiversity is a value that should be ranked much higher than previously. Monitoring of biodiversity needs a generation of people well aware what a rich ecosystem and biodiversity looks like and how to preserve or restore it. Much to do for teaching and learning professionals as well. Curriculum development for biodiversity and sustainability is in urgent need for updates. This has to include the socioeconomic dimension as well.

Global warming

The annual update of the global warming indicators (source: Earth system science data 2025-6) gives more reasons to worry about the future of our climate. The objective to limit global warming to +1.5°C, established at the Paris climate agreement in 2015, is no longer achievable. This is the hard evidence based on the global network of scientific data collections and their projections. Fossil fuels are a major cause, deforestation and greenhouse gas emissions as well (Forster et al. 2025). As a consequence, human-induced warming of average surface temperatures and flows of heat into oceans continue. The first consequences, we witness in many parts of the world already. France is particularly affected (Le Monde 2025-6-20, p.7). What used to be called “natural disasters” is better described as long-term consequences of human-induced global changes like global warming. About time to take our CO2 footprint even more seriously. The “All electric society” can reduce reliance on fossil fuels considerably, as of now.

Spring Newborn

For many species spring is the time for newborns to enter into life. Pigeons in the neighborhood have completed the breeding phase and they called upon the newborn to crack the shell open. Nourishment is already abundant in the surroundings and parents appear to be impatient to quit the guarding of their offsprings. Time for the next generation to take over a similar role soon.
Pigeons don’t ask questions about fertility. They reproduce in abundance if the environmental conditions are alright.
Human beings are a danger for them as some feed them well, but others defend their territory, housing or living space against any intrusion by pigeons. Compromises are not easy to accomplish.
Fans of the song writer Georg Kreissler keep humming with dark humor: „Geh‘n wir Tauben vergiften im Park …“. The struggle for survival of species has changed in kind and we are, more than ever, responsible for the living conditions of other species as well.

Warming consequences

The live of honey bees is rather busy and well organized. Global warming necessitates new risks and new opportunities for honey bees. The flowering season starts earlier in Europe and bees start earlier ro their collection of nectar and their service of pollination to other flowers. In early April 2025 in France near Paris we observe wild bees already in their daily routine. However, the risk of cold nights is still there, albeit those building their homes below the surface are a bit less at risk during a frosty night. Seeking a clever shelter is a good strategy for survival particularly at times of global warming. Some kinds of wild bees seem to sense this already changing homes from one season to next one. Humans remain their toughest enemies as they restrict their choices quite severely. Man-made pollution and herbicides are beyond bees’ control and cause havoc in the ecosystem of bees. Apiculture is an interesting science also for social scientists as this forerunner species of the matriarchy has evolved into a well-organized productive society. They are a bit harsh to each other and communication is rather unidirectional, but an interesting social cosmos of its own kind.

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).

Birds again

There are many ways to have more birds again in inner cities. Less pollution and poison are part of the solution. Second, increase the food available to birds. Some plants or vegetation is more suited than the other one. Combined with the question of cooling houses in summer and more isolation in autumn and winter, the greening of facades in cities has a simple effect to provide hiding, nesting and feeding spaces for birds. Birds will discover this vegetation as their natural habitat offering relatively safe shelter and food. It is an incredibly simple way to catch 22. Your new shelter is selective in the choice of birds that it will house. Singing birds seem to value the places most. Other predators may follow. At least in late autumn and early winter the energy rich power food is a welcome addition of the diet. Nesting in spring and summer might be another option to have more birds again. We shall need many very small steps again to keep biodiversity or bring back some of it. Birds again is a small initiative.

On Organics

Organics are the new hype. Organics are everywhere. It is true in organic chemistry, biochemistry or pharmaceutical biochemistry we start from organic compounds as the basis for various forms of classification systems, structures and reaction chains. A search for organics brings you to Organic Farming and to lots of other applications of organic production as well as organic design.
The extended definitions highlight the foundation in biology and chemistry to then include any processes which integrate cyclical reproduction or resources and conservation of biodiversity. Based on the plurality of forms and connectivity of organic compounds this leads to a vast and diversified basis of carbon- and hydrogen-based life on earth. The ensuing complexity (variety of species) has been the basis for mankind to come into being. It is likely to determine also our survival in the long run. Organics is based on open as well as closed forms and therefore has an encompassing nature. Depending on time and space constellations (temporality) evolution has taken one or the other path. We are certainly not at the end of this evolution, although we through the loss of biodiversity we narrow down new potentials in an unprecedented way. Rethinking life on earth from a cell-based perspective of plastics and chloroplasts is a challenge, but it will lead us on towards the “organic turn” in the 21st century.

Olympic Nature

Nature and its biodiversity can teach us many lessons. This is made very explicit in the small exhibition in the “Jardin des Plantes” in Paris. The treasures of (lost) biodiversity are exposed in the adjacent “Muséum National d’Histoire Naturelle”. In a pleasant environment within Paris you can stroll along rare flowers and trees to pass the posters that demonstrate the astonishing achievements of some species (Les champions of nature). For example ants would surpass us in weightlifting in relationship to own weight. A marathon of 42 km is a very short distance for birds flying across continents with rest. High jump or long jump is rather easy for frogs, but we struggle already to jump a little bit higher than our own body length. Lots of other examples are shown the exhibition and should make us a bit more humble concerning the sport accomplishments of humans. Beyond Darwin and Mendel there is a lot to see and experience in the Great Gallery of Evolution. After the question remains whether we are really at the top of the evolutionary ladder. In terms of marketing our successes irrespective of many species disappearing with rapid speed, we still appear rather unique in the evolution. Learning from other species as in bionics is a powerful strategy which is also quite effective to empower humans compared to other species.

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.

Forest Management

Responsible forest management is key. To safeguard against the loss of biodiversity the management of forests can achieve a great deal as the study in Nature of 2024-4-10 has demonstrated. Reducing hunting by humans in dense tropical forests allows bigger species to survive and thrive compared to forests with easy access by roads. FSC certification of forests helps significantly to protect wildlife. The ability to ameliorate biodiversity of forests is assisted by the Forest Stewardship Council (FSC) through the responsible management, preservation and limitation of access to wild forests. This is an important message that in fact it is still possible to preserve wildlife also of larger species if we only really commit to the cause. It is well worth to support such initiatives and monitor the progress. Of course, any such success attracts new hunters and a continuation of the FSC efforts is needed for the benefit of the whole biodiversity on our planet as there is no planet B.

Disappeared

We talk a lot in abstract terms of the loss of biodiversity. In the Museums of Natural History, like the one in Berlin, we can follow the trajectory of extinction of species. The dinosaurs are for most children the greatest attraction. No surprise, they are the biggest ones we have had on our planet. But there is a huge collection of disappeared species represented in the museums which we admire as a lost treasure or species threatened with extinction. Evolution had also created this rather big bird-like creature of the “dodo”. It couldn’t fly anymore and was inhabiting the splendid island of Mauritius. Hungry colonists passing have most likely literally eaten up this rather defenseless animal. Many other extinct species can be admired now only in museums and children feel naturally attached to some species that seem to have human expressions. Panda bears and gorillas rank high on such a list, but also some fish, especially if they smile or look at you straight into your eyes. This should help us take biodiversity and biodegradation more seriously. Children feel intuitively attracted to animals as natural companions. Something we have lost as adults and most of do not even realize this as a deficiency. The Nobel price winning author frm Mauritius has published a collection of short stories „Avers“ which captures the spirit of the island and the loss of species. J.M.G.Le Clézio seems to look at us through the eyes of children or a disappeared species. Magic moments are an escape as well as reason for hope.

Ethics of posterity

We have not inherited the earth from our ancestors; we are borrowing it from our descendants. (native American saying). Adeline Johns-Putra (2019) states this early in her book on “Climate change and the novel.” Her concern is how to think and write about the ethics of posterity. Approaches of ethics in the sense of parental care (for the planet) or motherhood environmentalism do not suffice in view of overpopulation of our planet. Shifting our identity away from toxic production and consumption is advocated in many novels. Science and science fiction offer many dystopian examples.
De Shalit (1995) wrote early on why posterity matters. It is not the standard of living of contemporaries that matters but we should consider ourselves as a part of a transgenerational community. The time horizon of our decisions matters. In pursuing arguments by John Rawls who re-established a contractionalist perspective on justice, we have to include future generations into our contractual obligations. Following this approach we might arrive at Brundtland’s perspective on the ethics of posterity which is called sufficientarianism in opposition to simple utilitarianism. In sufficientarianism we owe future generations a just and decent living or at least the possibility to have similar starting conditions. Shifting beyond the apocalyptic view of environmental disasters Adeline Johns-Putra (2019) brings to the forefront that we have to substantially lengthen  our time horizon both for consequences of climate change and for dealing with it, albeit the fact that most destructive practices operate much faster than the re-establishing of greater biodiversity.
P.S.:Thanks to the curators of the Lese Lounge Staatsbibliothek Berlin for ease of access to the literature.

Auenlandschaft

Die Auen und die Wälder in der unmittelbaren Nachbarschaft hatten eine hohe Bedeutung für die Biodiversität. Mit ihren fruchtbaren Böden waren sie leider sehr begehrt für die Landwirtschaft und wegen Wassernähe auch für Wohnungsbau. Die Auen haben eine wichtige Funktion als Aufnahmefläche für Hochwasserschübe an allen Binnengewässern. Das haben wir in Deutschland an der Ahr schmerzlich wieder erleben müssen. Nachhaltiges Wirtschaften mit den Auen statt gegen die Auen ist möglich. Selbst der langsame Rückbau von befestigten Flussufern ist möglich, wenn Ausgleichsflächen für Überflutungen erschließbar sind. Das braucht eine langfristige Planung. Diese fängt meistens auf den umliegenden Bergen und Hügeln an, die nicht mehr nahezu ungebremst große Wassermengen rasch in die Flüsse ableiten. Auffangbecken, die höher gelegen sind, Versickerung, die nachhaltig bewässert, sind verbundene Planungsvorhaben, die zusammengenommen eine wirksame Antwort auf den Klimawandel bilden.
Auen haben feuchte- und wärmeregulierende Funktionen, die den umliegenden Dörfern und Städten zu Gute kommen. Elektrisch betriebene Schiffsmotoren drehen leicht mit höheren Drehzahlen und Vermeiden dadurch zusätzlich die hohen Heckwellen, die sonst oft bei langsam drehenden großen Schiffsschrauben zu beobachten sind. Als Naherholungsgebiete sind die Auenlandschaften sehr beliebt und nicht erst seit den Malenden der Romantik. Die größere Biodiversität sollte eine Antriebsfeder sein, diese Naturschönheiten zu bewahren und, wo möglich, wieder herzustellen. Leipzig hat das erfolgreich durchgeführt (Link PDF). In Frankreich tragen die Rückhaltebecken der Marne wesentlich zur Verbesserung der Wasserqualität der Seine bei damit mittelfristig darin sogar wieder gebadet werden könnte.

Geologie

Mehr GeologInnen braucht das Land. In der Schweiz beunruhigen derzeit zunehmende geologische Risiken. Der Klimawandel lässt Permafrost in den Höhen schmelzen, der jahrhundertelang Gestein zusammenhielt Gleichzeitig sinkt die Schweiz, nicht die Aktienkurse, selbst die Credit Suisse ist bereits untergegangen, aber rein geologisch, nüchtern betrachtet (NZZ, 2023 „Die Schweiz sinkt“). Das verlangt nun doch einige gründliche wissenschaftliche Untersuchungen. GeologInnen messen bereits mit unzähligen Messstationen die Bewegungen der Erdkrusten. In der Schweiz lässt sich sicherlich mit dem zunehmenden Abschmelzen der Gletscher und der Veränderung der (mehr) Regenfälle statt Schneefälle in den frühen Wintermonaten eine neue Gefahrensituation aufzeigen, nicht nur für den Tourismus. Die üblichen Reflexe: mehr Investieren in Schutz und neue Versicherungen wird alleine nicht mehr helfen. Biodiversität auf den unteren Skipisten ist eh Fehlanzeige, aber die Baumgrenze steigt. Das könnte genutzt werden, statt die vielfach kranken Fichten, die wegen ihrer kurzen Wurzeln kaum ein Gewitter überstehen (Ruinaulta vom 4.8.2023 S.6 und S.16-18). Diese Gewitter werden durch den Klimawandel wahrscheinlich häufiger werden. Noch mehr Versicherungen werden die Welt nicht retten können. Wir werden umdenken müssen auch wenn Verhaltensänderungen sehr schwerfallen.
Das Abbrechen von Bergspitzen, wie am Kantersteg (BE) oder der Bergsturz am Piz Cengalo 2017 in Graubünden, ereignen sich dann eher in den wärmeren Sommertagen. Die GeologInnen werden viele Arbeitsstellen haben (nicht nur im Geopark Sardona UNESCO Welterbe) und gehören zu den Berufen mit höherer Nachfrage durch den Klimawandel.

Greenwashing

We mostly think of greenwashing of big polluting industries , but there many other ways to cheat with green labels. When you travel through green Switzerland you might be surprised of how the Swiss way of greenwashing works. In order to survive as tourist attraction with less snow (Study published in Nature Climate change 2023) and reduced numbers of trees, greenwashing has to happen quickly before tourists arrive again.

The challenge is to clear your sick parts of the forest quickly and to build new ways for fast lifts to heights in the mountains where you are likely to find snow at least for the next 30 years after which the investment is amortized. (quote from Neue Zürcher Zeitung 5.8.2023 p11). This all is carried through in speedy fashion and probably in the most polluting way you can imagine. Heidi would cry in the arms of her grandfather and join Greta in the school strike.

Garten

Ach es ist so schön im Garten. Ein schöner Garten will geplant werden. Das gelingt auf besondere Weise mit dem „Pollinator“. Hinter dem Pollinator verbirgt sich ein Kunstprojekt, das viele kleine Gartenkunstwerke zu einem großen verbinden möchte. Spannend ist nicht nur das Vernetzungsprojekt von vielen einzelnen Parzellen zu einem größer werdenden Gesamtprojekt (Aggregation), sondern der für Kunstschaffende gewohnte Perspektivwechsel. Aus Sicht der Bestäuber der Pflanzen und Blumen gesehen ergibt sich eine vogelähnliche Perspektive auf den Garten.
Der Parcour einer Biene oder eines Schmetterlings durch unsere Gartenparzelle regt zum Träumen an. Vielleicht hätte Franz Kafka nach der Parcour-Erfahrung ein anderes Insekt gewählt. Mir gefällt die 2D, 3D, 4D Perspektive, die es erlaubt, den blühenden Garten im Zeitraffer durch alle Jahreszeiten zu visualisieren. Das ist Gartenarbeit ohne die mühsame Kleinarbeit des Pflanzens und Unkrautjätens. Es wird nicht gleich ein Garten wie von Impressionisten in Argenteuil von Monet oder in Yerres von Caillebotte daraus, aber ein farbenprächtiges Kleinod allemal. Mein erster virtueller Versuch (Link) ist schon recht farbenfroh. Lateinische Namen auffrischen ist schon fast ein Beitrag zum gesunden Altern, besonders wenn der Garten einige Kilometer entfernt ist. Im Sommer lassen sich leicht neue Pläne schmieden. Herbst und Winter, Trockenheit und Hitze lassen uns das Gartenkunstwerk nochmals überdenken. Spielerisch ein Gartendesign gestalten, kann der erste Schritt für mehr Natur sein. Biodiversität macht Spaß und hilft uns allen. Kleinvieh macht eben auch Mist.

Car Energy

The car industry sells more electricity-driven than diesel-cars for the first time in July 2023 (ACEA, 2023). This is a turnaround, considering the large share of the most polluting cars in the EU. It is difficult to see this as good news as newly sold diesel-cars will be around and polluting for many years to come. Hybrid cars are an own category and full of heavy additional material that allows 2 types of mobility. Tax reductions to push hybrid cars into the EU-market were very expensive for tax-payers and increasing inequality through co-financing rather expensive cars. 36,3%, the largest share, are still petrol-driven cars, with little awareness for further CO2 reductions. This is the slow evolution of the energy consumption pattern of the automotive industry in Europe.
On the energy production side there have been substantial efforts to invest in clean energy, too (IEA, 2023). With the world burning at several places already it is, after all, good news that investment in solar energy production on a global level has reached the level of investment in fossil fuels. Major drivers of this evolution are 1. China, 2. Europe and 3. The U.S. A. (unadjusted for population size) according to this investment report. Grids and storage investments rise equally to new heights, reflecting new distributional aspects of power provision within and between countries. We are in the race against the burning of our planet due to our shameless use of fossil fuels, worst in form of flying small jet planes. Besides the large company and state investments we need the spending and investment power of the masses to speed up the end of the fossil fuel age of polluting dinosaurs. Please do not replace one dinosaur (coal, oil, gas) with another one (nuclear). Too big to fail is maybe an economic rationale, but it does not withstand natural disasters (Fukushima), human failure (Tschernobyl) or war activity (Saporischschja).

Schwalbe

Verzicht auf Spritzmittel wie Gluphosat in großen Mengen an Bahngleisen, Autobahnen und sonstigen Verkehrswegen kann schon viel helfen, dem Artensterben zu begegnen. Unkraut zupfen im Weinberg, Nutzgarten oder Ziergarten, statt die chemische Keule einzusetzen, beginnt Wirkung zu zeigen. Zarte Ansätze von Biodiversität sind beispielsweise die Rückkehr der Schwalben (Hirundinidae)  in vielen städtischen Bereichen. Das freut sehr viele Menschen, die das Zwitschern der Schwalben lange vermisst haben. Die Schwalben ernähren sich hauptsächlich von Insekten. Genau diese Insekten werden aber mit den Spritzmitteln ebenfalls vernichtet. Das führt nicht nur vielfach zu erheblichen Gesundheitsschäden beim Menschen, sondern lässt sich an dem Vogelbestand bereits gut ablesen.
Daher ist es ein gutes Zeichen, dass die Schwalben zurückkommen. Wir bieten mehr Nahrung, Brutstätten und weniger Umweltgifte in den Innenstädten. Nebenbei braucht der Stadtneurotiker dann auch weniger in das Umland auszuschwärmen, um urwüchsigere Landschaft und Klangwelten zu erleben. Ein paar Singvögel leisten damit sogar einen Beitrag, die persönliche CO2-Bilanz aufzubessern.
Für alle, denen Vogelstimmen zum Wohlbefinden beitragen, hier noch ein Link auf die umfangreiche Hitliste der Stimmen der Mehlschwalben. Von dort lässt sich die Vielfalt weiter erkunden. Für Musikliebhabende lässt sich im Internet auch eine Webseite zu der Verwendung von Singvogelstimmen in der meist klassischen Musik und darüber hinaus, finden (BR-Klassik).
Schwalben schlagen zudem jede Wetterapp in der Kurzzeitvorhersage von Regenschauer im Sommer. Ein nahendes Tiefdruckgebiet mit Regenschauern zeigen die Schwalben bereits mit Tiefflug-Akrobatik an. Der richtige Indikator verbessert eben die Vorhersage. Das können Ökonomen und Meteorologen aus der Biodiversität lernen. Wir erfreuen uns einfach an dem Zischen der Schwalben im Flug und lassen uns inspirieren oder amüsieren uns an anderen Spielarten von Schwalben (Moped, Fußball, War and Diplomacy).

Ground Water

The European Environment Agency collects annual data on pesticides in the ground water. The water most of us use in some form or drink. This used to be possible without too much thinking a generation or two ago. We now learn that this might be more and more dangerous, particularly in areas, where less rainfall and prolonged periods of draughts most likely increase concentrations of pesticides even in our tap water. Drinking this, raises more concerns. We know that in big cities and nearby of hospitals water quality is worse due to the concentration of particles from chemicals applied to increase contrasts in medical imaging. Pesticides are mainly used in agriculture, road and rail maintenance, but also households apply them for simplicity.
Snails (escargots) might invade your garden and even your home at times. However, it is just a little bit of exercise to “relocate” them in a decent place other than your home. Prepare a race for several ones and bet on who is going to win, but please refrain from the  use of more pesticides. Several species of them are consumed and, depending on your taste, considered a delicious part of a meal (for example in Bourgogne, France). It should be easy to agree to stop the heavy use of pesticides across Europe and beyond. We shall have to protect the salads we grow differently. Human intelligence is able to allow other solutions than just killing as efficiently as possible ,at the same time, endangering our own species.  (Comparable data EEA below).

Waldbrände

Waldbrände sind leider jenseits vom Süden Europas auch im Zentrum von Europa ein Bestandteil der täglichen Gefahren geworden. Vor 50 Jahren waren die seltenen heißen Sommer die große Gefahr. Seit einiger Zeit bemerken wir öfter heiße Sommerwochen, die die Wälder austrocknen und leicht entzündlich machen. Jetzt haben wir die noch frühere Sommersaison nicht nur im Süden, sondern auch im mittleren Europa. Neben den Bränden in der Lausitz in Deutschland, kämpfen Feuerwehrleute öfter in den französischen nördlicheren Waldregionen mit Bränden. Eine Nachricht, wie die zum Brand Anfang Juni im „Forêt Fontainebleau“, sollte uns klar machen, da brennt unserer europäisches ökologisches und kulturelles Erbe. Jeder hat die brennende Kathedrale „Notre Dame de Paris“ noch in Erinnerung. Da war Klimawandel nicht die Ursache. Bei den Waldbränden sieht das anders aus. Das Ergebnis ist das gleiche. Die Vernichtung unseres kulturellen Erbes schreitet voran ohne Prävention. Das ist eine zentrale Aufgabe. Nicht erst in der Zukunft. Prävention verlangt Handeln, Planen und Implementieren schon heute. Das ist ein riesiges Qualifizierungsprogramm nötig. Es umfasst die Sensibilisierung für die allgegenwärtigen Gefahren genauso, wie das Schulen allfälliger Einsätze von professionellen und freiwilligen Helfenden. Gefahr erkannt, heißt leider nicht schon Gefahr gebannt. Da gibt es viele Zwischenschritte, die geprobt sein wollen, damit ein effektiver Einsatz gelingen kann. Es bleibt viel zu tun, packen wir’s endlich an. (Artikel in La Marne 7.6.2023 S.6)

Birds

The study published in PNAS in May 2023 is demonstrating the loss in bio-diversity with respect to birds over last few decades. Our economic growth has caused considerable costs. Some of these costs we shall never be able to make up again. Species gone for ever, we should care. Measuring the loss is a first step in calculating the negative impact our economic growth models have already caused. Time to stop, repair and reverse as much as we still can. It is not fair to next generations to destroy a large amount of bio-diversity now and leave the exploited planet to “no-future generations”. A good documentation of the losses (radio-france-LINK) allows us to pin down who is most responsible for the losses. Agro-industry with the heavy use of pesticides is well known for the huge negative impact it has on bird populations and us as well. It is not only a European issue, but rather a world-wide issue. However, starting at home is a huge step to practice agriculture differently. Most of this is known for some time. It is the implementation of the necessary policies where powerful lobbying is successful to carry on as usual. Thinking “Beyond growth” delivers many useful perspectives and solutions to these problems.

Put People First

Put people first is a natural claim of human beings. We tend to abstract from the fact that we implicitly rely on a sufficient biodiversity for our survival. Therefore, the natural claim to put people first has many preconditions itself and severe implications. The most obvious implication is related to our world of production and consumption. We need to build an economy that serves its people rather than one that uses up human resources and discards people to an inferior rank of importance. Externalising health and safety at work to save money in the process of production will only cost society much more later on. This needs to be part of the balance sheet of companies not only “national accounts” or relegated to some health statistics hardly known to the public.
Put people first in consumption, has come to our attention recently. With energy prices rising due to Russia’s war on Ukraine territory we have learned that energy prices may be grossly distorted. Firms’ versus consumers’ energy consumption became a thorny issue. Even legislation, like in Germany, that put people’s energy consumption before companies’ consumption of energy became subject for debate.
Same issue with artificial intelligence. Let’s put people first here as well. Discriminating use of language or biased conclusions due to wrong data input to train AI is not acceptable as excuse. AI may serve humans in their work or leisure, improve production lines through error detection or early onset of disease, but it cannot replace the human verification of a just or otherwise justified human intervention. Humans are not perfect, never will be either. This is a tough rule to teach the algorithms that guide AI. Put people first has a strong interpersonal or solidarity element enshrined in it. This is what matters, now, in the medium term as well as the long run.

Beyond growth

We have reached the bio-physical limits to economic growth much earlier than most people and experts expected. The “Beyond growth conference” at the European Parliament 15.-17.5.2023 is quite unanimous in this verdict of collective failure. Some advocate “degrowth” in various forms. Maybe the framing of how to address the vital topic of how to set objectives for a post-growth economy needs an even broader perspective. It is a global issue, but the industrial growth societies around the globe will have to work together to find and implement solutions. The worldwide conference COP-XY are hardly delivering on the issue. At best they satisfy the ego of political leaders to address important issues providing nice images from nice places in the world (Paris agreement) to advance their own political campaigns.
From an economist’s view rather than solving a very complex issue with uncertain outcome, it is more instructive to, for example, start to produce the same economic and social well-being by using much less natural resources above all climate-toxic elements (Carbon-dioxide CO2, Chlorofluorocarbons CFC, or methane). These are simple first steps with a rather immediate effect. After the recent crises we have learned to safe resources (heating) and reduce mobility, just continuing on this trajectory is feasible. Vastly excessive forms of consumption need to be capped through targeted taxes that allow redistribution or investment in reduction of pollution. It isn’t hard to do, or “It’s easy, if you try“, we might sing.

Biotop

Die Sensationspresse, zu der leider mehr und mehr ehemals seriöse Zeitungen neigen, zitiert Biotope meistens als Wirtschaftsbremse, Wachstumsverhinderung oder Spaßbremse. Da fällt es schwer dagegenzuhalten. Biodiversität ist nicht umsonst zu haben. Viele Schmetterlingsarten leben bestens angepasst an ihr ökologisches Umfeld, vergleichbar einem Biotop. Farbenpracht dient zur Tarnung im Gelände oder zum Anlocken von Paarungspartnern. Im Botanischen Garten in Berlin werden solche Inseln der Glückseligen für viele Regionen Europas und darüber hinaus nachgestellt. Der frühe Schmetterling von Ende April ist kaum zu bemerken, so gut passt seine Farbkonstellation in sein Umfeld. Es werden richtige Suchbilder und Geduldsproben, die Falter zu entdecken (bitte unten testen). Belohnung lockt für die Geduldigen, wenn das auch vielen von uns unerträglich schwerfällt. Zu schnell sind die Umgebungen für vermeintliche, kurzfristige, wirtschaftliche Interessen zerstört und die angepasste Tierwelt ebenso. Das Bundesnaturschutzgesetz (BNatSchG) intentiert einen Schutz. Der ist aber wohl allzu leicht auszuhebeln. So wird die Farbenpracht und das Tanzen der Schmetterlinge zunehmend in Konzertsälen zu hören oder darüber zu lesen sein, aber seltener in Biotopen zu bewundern sein. Artenvielfalt als Biodiversität braucht die passenden Räume dazu. Eine große Aufgabe bei dem weiteren Anwachsen unserer Spezies.

Biene

Die Tulpen haben dieses Jahr wieder alles gegeben. Die lange Trockenheit im März und der ersten Hälte vom April hat die Tulpen lange blühen lassen. Zwei kräftige Aprilschauer haben der intensiven Blüte ein Ende gesetzt. Eine große Träne bleibt noch auf den Blättern. Jetzt sind schon die Bienen, noch mit Mäntelchen, aktiv und bestäuben recht fleißig die anderen Blüten. Wir freuen uns dann schon einmal auf die nächste Tulpenblüte im Garten in 2024.

“Musée du quai Branly – Jacques Chirac” receives relatively few visitors compared to the much more popular art museums in Paris. The proximity to the Eiffel tower, however, allows easy access within walking reach from the most visited tourist attractions in Paris. A cheeky impression of the design of the building and surrounding gardens of the Museum resemble to me a shadow of the Eiffel tower in the afternoon sun in Paris. Some might even say with a westerly wind the tower would fall exactly on the museum. No, of course the tower is not tumbling. In the shadow of the tower there is superb place to meditate in the gardens or enjoy the many exhibitions of cultures from across the world. In remembrance of former President Jacques Chirac, Asian cultures have had a strong impact on the collections and the organisation of the garden. Very different from the French park “à la Le Notre” at Versailles or Fontainebleau, the garden of the museum du quai Branly follows a completely different design focusing on bio-diversity. The architect “Jean Nouvel”, is quoted having said, that the garden is not a complement to the museum, but the garden is the museum. Hence, it is possible to have very unexpected views not only from the museum buildings, but also of the Eiffel tower nearby. It is possible to view the Eiffel tower through different continental perspectives on it. To the extent that you might not even recognize the massive tower in the neighbourhood being immersed into wild life. Then try one of the special expositions or the permanent exhibition, if visiting for the 1st time. We travelled continents without devastating CO2 effects. Additionally, Paris is easy to reach by train. You may complement the intercontinental experience by visiting the headquarters of UNESCO, at least the book shop, in Paris also nearby.

Quercus

“Quercus petraea” is the classification name of the sessile oak, the Irish Oak or “chêne sessile” in French, “Eiche” in German. Many European nations cherish their oak trees. It can reach the size bigger than a normal family home and they may live longer than the person who has planted it. Within less than a century, due to industrialisation, most of our more than a century old trees have been lost or used for timber wood. Therefore, it is quite unique to find a reference to a 500 year old oak tree nearby Paris. Despite a fire in this forest 5 years ago (climate change in full action) the old oak tree has survived. Birds around  keep spreading the message that it is worth to preserve nature. We could do it, if we really wanted. Now the oak tree older than the protestant revolution is a rare testimony of the stubbornness of nature to resist.

Wasser im Wald

Wasser im Wald hat viele Funktionen. Historisch erleichterten Wasserstellen an denen sich Wildtiere genüsslich im Morgengrauen laben, die Jagd des erschöpften Monarchen. Einfache Ziele, die jeder Jagende sich zu nutzen machen kann. Kleine Seen dienen aber auch als Wasservorrat beim Löschen von Waldbränden und nicht nur den Badenden im Sommer. Viele kleine Seen in Frankreich leiden an erheblicher Wasserknappheit. Wasserstände, die sonst im Spätsommer erreicht wurden, nach Trockenheit und Verdunstung, sind im Frühjahr 2023 berreits erreicht. Ein Waldbrand könnte kaum mit vor Ort vorhandenen Wasserreserven gelöscht werden. So hängen Feuer und Wasser im Wald recht eng zusammen. Austrocknende Seen vernichten zusätzlich die Biodiversität im Wasser, denn weniger Lebensraum im Wasser hat Konsequenzen. Das heizen mit den Motorrädern im Wald, hab ich selbst gemacht vor vielen Jahren, ist heute eh schon verboten. Aber Verbote und Jugend sind ein eigenes Thema. Wir haben der Jugend die Freiräume geraubt, die wir noch hatten und jetzt beschweren wir uns über die stubenhockenden Jugendlichen mit ihren Computerspielen und Social-Media-Aktivitäten!?! Ein völliges Überdenken des Wassermanagements ist von Nöten. Das sind wir den nachfolgenden Generationen schuldig. Welche Arroganz besitzen wir, dass die Jugendlichen von Heute viel klüger und noch schneller erwachsen sein sollen als wir selbst in diesem Alter. Aus Fehlern lernen wir, aber wir scheinen das Lernen, den späteren Generationen überlassen zu wollen. Leider funktioniert das so nicht, wir müssen schon an unser Verhalten ran und von uns verursachte Schäden selbst reparieren. Das Fegefeuer brennt schon, ob wir es noch rechtzeitig löschen können?
