Concorde

„These were the days my friends, we thought they’d never end …“ And yet the Concorde served for decades as a massively polluting aircraft for those paying or had their flights paid be their enterprises to cross the Atlantic ocean. Yes it was the fastest way, but we learned that it didn’t really make sense. After a technical default with an explosion the entire craze got stopped. Now next to Orly airport the remainders of this undoubted design highlight is exposed. It serves more as a warning that not all technical innovations are viable as commercial or ecological innovations. The delta-design as aircraft is still the most common design children play around with as paper models. Wing designs have made progress to adapt the bent end on each wing. So should do our paper models of them. The Concorde is also a perfect example to learn from concerning the link between “Society and Technology”. Similar mistakes seem to occur still today. “When will we ever learn, when will we ever learn…”.

CO2 Footprint of Books

In view of the worldwide size of book publishing we should also keep an eye on the CO2 footprint of book publishing. The Italian association of publishers gave a brief overview of the likely CO2 footprint the printing of a book causes. Their best guess is at ½ a kilo of CO2 on average. For simplicity of calculation and assuming that an editors’ association is unlikely to overstate the amount, let us assume it is 1 Kg CO2 per book. The most CO2 is consumed not in the book production but in the transport of the items, machinery and personnel involved in producing, editing, selling etc. Of course, paper is recycled to a large amount. Certified sustainability of paper from trees has become a standard in most countries.
Nice twist to the issue: your own library at home has become a CO2 storage, if you keep them or lend them or pass them on to others. Reading can be a little bit addictive and buying books as well. Reading online or electronic books reduces your CO2 footprint. The best way to imagine the reduction of your CO2 footprint, however, is to buy or to borrow a book on travelling which replaces the actual journal by reading on the couch. Yes, being a couch potato is good for the planet, and if you want to buy a book, walk to the book shop or the library if possible. If you enjoyed flying previously shift over to buying books on planes, airports, clouds in images or stories that involve extensive travelling instead for the sake of your own CO2 footprint and future generations.
Even a book will need somehow wood as input, many alternative ways of leisure time or professional activities are worse in terms of CO2 footprint. Any e-book, e-journal or e-newspaper is even better for the planet, especially if we think of the millions of paper copies across the world that are printed but never sold. Knowing your market is crucial to reduce misallocation of ressources. E-books are so much easier to store as well using regenerative energy for the content servers around the world.

Civil Protection

A lot of important activities do not receive the attention they deserve. During a humanitarian crisis, Europe frequently acts with varying involvement of Member States. This holds true in droughts, inundations, earth quakes, civil wars or imperialist state conflicts. The extent and time of commitment are an additional and differentiating element. Coordination of such activities is important for those wanting to help and those asking or receiving assistance. Efforts, equipment and political support vary enormously as well. There is a need to approach this topic more strategically. The Union Civil Protection Knowledge Network (UCPKN) goes a long way to attempt to find a common language, data infrastructure and responses in this respect. It surely is important to go beyond the piecemeal approach of the past to be able to address emergencies in multiple kinds more effectively. It is, however, also in some instances a highly controversial issue as well. For each term in this old (Tschernobyl nuclear disaster) and still novel field (Fukushima) for joint activities, we have to come up with compromises of definitions.
For example, what constitutes an emergency? Does the climate crisis and disasters related to it already constitute an emergency now? Some say yes, we have to act now to avoid bigger floods and wild fires as of next year. Others, do not want to tackle the root causes, but rather focus on curing actual devastating effects of disasters.
We are back to a well-known topic of preventive rather than curative approaches. In the meantime, we are convinced that we have to commit more resources to both approaches: immediate relief and structural change to prevent an otherwise never-ending sequence of disasters in varying places.
Most important probably is the keeping of address books and fast digital networking facilities to react and communicate with the competent institutions and civil organisations. Beyond the involvement and linking of experts in the field, the larger public and volunteers make up for additional invaluable resources to act.
It is crucial to make it possible for decentral links between cities like in city partnerships to be involved. Building on existing human to human links motivates and mobilises huge additional resources. Of course, continuous training is a very important element in all those efforts. We should embrace it in the private and public sector, at school and in retirement even. (Image: Extrait de Peter Paul Rubens La chute des géants MRBAB, Brussels)

World in Common

The Tate Modern Gallery in London has an exhibition of photography on display which challenges our Western view of art works. With a focus on photography and African photographers it is complementary to the many other photo exhibitions. We have a world in common, says the title of the exhibition. The images, however, reveal another vision of African photographers. Other perspectives on beauty, architecture and the distribution of wealth and waste across the world becomes explicit. Beyond the documentary effect of a lively African scene of photography and past colonialism the forward-looking vision of African photographers is also evident. Colours and Imagination of a unique kind allow us to look beyond the current state of affairs. Rising from the ashes and western waste the colours of Africa will prevail.
Only through the force to imagine a different trajectory for the continent we shall eventually be able to see new flowers blooming.
Positive images have to be put in front of the “negativity bias” in Western media when reporting about African countries. The light, the sun, the sea and coast lines, all can contribute to the rise of Africa in various ways. The photographers in the Tate exhibition demonstrate an impressive power to go beyond the day-to-day topics.
Broadening our scope of visuals with more images from Africa certainly are  fist steps to enlarge the spectrum of photography and art. A chance to browse through the catalogue allows to go back from time to time to counter our usual stereotypes. (Image taken from Tate catalogue A world in common, 2023 Muluneh Aida 2018 p. 202-3).

Trees

Looking at trees is relaxing. At least this is true for most of us. Some researchers, however, have a stressful time to sort out what it is exactly about trees that causes this impression, perception or feeling. Time to do a few studies on this issue (Lancet RM, 2023). Most likely it is the size or the number, maybe the surface or volume covered by trees that have an impact on us. Maybe it is the sequence of seasons that really causes the pleasant feeling about trees. Perhaps the fresh air, shadow in summertime or more the birds and squirrels or dogs that „inhabit“ the trees in neighborhoods that are important to us. More and more cities really develop sizable programs to care about their green spaces. In a simple cross-sectional study it seems the visibility of trees that is important rather than other effects. More sophisticated second round effects like oxygen levels or meeting points like in rural areas seem not to matter as much in cities currently. The study cited below invites us to devote more consideration to trees which we took for granted for far too long.

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.

Berlin Grün

Zur Berlin Art Week BAW 2023 wurden der Neuen Nationalgalerie ein paar Blumen und Baumkästen spendiert. Alles nur vorübergehend. So erblühte die Rose von Isa Genzken schon vorher und sicherlich noch etwas länger vor der Neuen Nationalgalerie. Steht der Galerie gar nicht schlecht. Vielleicht etwas sehr figürlich und wenig auf die Schätze der Moderne hinweisend. Das ist schon eher post-modern. Rückbesinnen auf die Werte der Natur, dass Stahl und Glas eben nicht umsonst zu haben sind, sondern erhebliche Umweltkosten mitsichbringen. Das regt zum Nachdenken an. Solarzellen, quasi unsichtbar auf dem großzügigen Flachdach der Galerie und für die geplante Scheune nebenan? Kunsträume stehen ebenfalls in der Verantwortung für die Überlebensbedingungen unseres Planeten. Denkmalschutz kann weitgehend eine Bremse sein, aber die energetische Verantwortlichkeit der immer gut gekühlten und beheizten Räume sollten auch wegweisend in dieser Richtung sein. Da gibt es noch viele Potenziale, die es auszuschöpfen gilt. Damit kann dann auch mehr Kunst gezeigt werden, da die laufenden Kosten gesenkt werden können für mehr als eine Wahlperiode oder Amtsperiode einer Hausleitung. Also Kunst kann einen schon auf unangenehme Gedanken bringen, die die Kunstschaffenden und Kuratierenden selbst betreffen. Isa Genzken und die BAW setzen Zeichen, die vielleicht so gar nicht unbedingt geplant waren. Nice.

Get mobile

In inner cities, plagued by horrible traffic jams and pollution by cars and lorries, we dearly await at least the one day per year without this nuisance. Mobility can be organized differently. Brussels demonstrates this in an exemplary fashion. Many families gear up for this one day to teach kids how to cycle technically without the dangers of the fight for space, speed and breathable air. Older persons also feel much more save then and walk or cycle longer distances than they usually do. So many winners and only a few forced to not use their cars during 10 hours. Massive health benefits for the whole city, especially on too warm a day in autumn 2023. All these kinds of ideas were already discussed before the COVID-19 crisis on a mobility fair in Brussels. It is not the ideas that are missing, but the political will and courage to try new ways forward. Learning that walking and cycling in cities do not hurt you, prepares the readiness to go further along this path. Just do it. And do it faster than in the past. The planet needs it, people seem to really like it, too. Enjoy.

Energy Food

For more than a decade now researchers have shown the link between energy prices and food prices. At first sight this might seem surprising. In traditional or romantic associations with growing food, there is no link between the cost of energy and food production. Growing crops in your garden does not need more than sunlight, soil and water. Yes, that was long ago. Industrial production of food is heavily relying on energy to heat, feed and water plants or animals. Additionally, the supply chains have become far more distant, which increases the CO2 footprint even further. Therefore, it is no longer surprising that a great number of econometric studies confirm the close link of energy prices and subsequent pressure on food prices. This is not restricted to Europe, but has reached global contamination.
Enjoying seasonal local food is a double catch solution. You grow according to local weather conditions and use traditional conservation methods, if the crop is exceeding your demand at that time. Providing heating for animals to increase productivity or quality of products appears to be one of the most wasteful ways to further increase the spiralling up of energy and food prices.
In agricultural science there is a lot of research into the “energy intake” of animals to better grow or produce more milk etc. This is the expensive intermediary step using energy to produce energy intake for animals rather than humans. It is surprising that we take so many years to address these well-known linkages that have turned to serious problems after Russia’s war on Ukraine. Agriculture and farmers can be part of the solution rather than a problem themselves, if the link of energy consumption and food prices is taken seriously.

10000

In France 100.000 is associated with Monsieur 100.000 Volt Gilbert Bécaud due to his dynamic singing and performance style. Since August 2023 we now have an additional association with the number 10.000.  Ten thousand m3 was the size of stones that came down from the mountains near the popular skiing resorts in the French Alps (Le Monde Link+video). To visualize the amount, a back of the envelope calculation with a standard container size of 25 m3 returns 400 loads of lorries to be removed from hard to access landscapes. Count this into the costs of running ski resorts.
A study in the scientific journal “Nature Climate Change” in 2023 highlighted the increasing risks to European skiing sites. Same holds for the Alpes in Switzerland.  Some areas relying on water resources to create artifical snow do so in less and less safe areas. Costs accrue to communities who benefit only indirectly from the skiing hype, celebrating 100 years of Olympic skiing next year. After all it is big business to sell or lend equipment, provide hotels and meals for all those sports women and men.
The so-called collateral damage is probably even worse. Interrupted railways, bridges, motorways and traffic in general becomes a severe disruption for quite some time adding to the total costs of having fun in winter. Is it worth it? A tricky question to ask in a referendum. We shall have to revise our past decisions to expand skiing resorts in light of the new evidence of higher risks and costs involved. A book on 10.000 years of history of glaciers is full of side-effects of glaciers melting away, which cause instability to valleys on the sidelines. In the most recent break-up of rocks it is actually more the access to the skiing resorts that was blocked, but this demonstrates to all: passing this area now, is not without serious side-effects.

Political theory and inflation

A political theory in the area political economy is prone to be labelled as classical, neo-classical, Keynesian, Neo- or Post-Keynesian or heterodox economics. This is a university level course in the history of economic ideas, if you like this. Let’s try something creative here. We have unprecedented levels of inflation currently in Europe and many other parts of the world. Reasons for this are higher prices for energy, transportation and food. Anything else you need for life? You must be an artist or a priest, a bit off the normal, it seems to many economists. Add to this that, we want to foster strategic autonomy in Europe rather than anything from China that is cheaper and more polluting. In 2023 we have inflation stay with us for some years. Central banks give out warnings in this direction now as well, having negated the problem for far too long (their own statistics ECB on long-term forecasts of inflation).
Besides the ample economic advice (IMF), depending on which theory of money and the economy you adhere to, political theory allows a refreshing perspective on these economic facts and trajectories. (1) From an international strategic perspective, countries that have to renegotiate a lot of their debt or take new credits to finance imported food, energy or transport will run into insolvency rather quickly. Self-sufficiency becomes an economic asset not only a geo-strategic one. Turn around globalisation is a side-effect.
(2) Countries eager to build new public infrastructure, irrespective of concerns for bio-diversity, might reschedule or abandon huge projects, thereby reducing their CO2 footprint. This reduces the official counting of GDP, but has beneficial effects to save the planet in the medium term.
(3) Individuals and households will have to reconsider their consumption patterns: more expenditure for food, less for energy and/or transport. Behavioural changes might be induced by inflation. Less of some form of consumption, guided by inflation, will induce reductions in CO2 most likely as well.
So far this is only applied economic theory as in any textbook. A more challenging political economy question is to ask: can we come to like inflation? Can we change our preference set (ECB growth dogma) for economic variables? Southern countries in Europe seem to like inflation more than the North. Does this depend on historical experiences or is it cultural or personality trait? There is again a huge money transfer due to inflation within the Eurozone. The less indebted countries pay with loss of their purchasing power of their savings and indirectly pay for the highly indebted countries mainly in the South. European and international solidarity will be put to a tough test.
As governments fear of being voted out of power they tend to soften the price signals from markets. Again, it is cultural more than economic to what extent people are willing to accept state interference in economic affairs even of households need for food. From an ecological point of view inflation could be our friend due to the potential to induce behavioural changes. However, more expensive bio-products seem to get crowded out due to further price rises and many even middle-income households seem to return to cheaper non-bio food in many countries. The distributive effects of inflation are a major issue here. Same rationale seems to apply to transport. If you can no longer afford CO2 saving transport by train, since it has become overly expensive more people are likely to take a heavily polluting low-cost flight to your holiday location.
Hence, from a political economy perspective liking inflation might well turn out to be a rich, white man’s perspective on the economy as the global South is likely to suffer most having no resources left to invest in energy and CO2 -saving in general. Price signals may induce behavioural changes for the better of us all. However, the story it is not only about allocation of resources, but also about distribution. There we should embrace a renewal of trade union strength to correct imbalances in the distribution of earnings as the basis for consumption and investment of households as well.

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).

Himalaya

In May 2023 we commemorate the 70th anniversary of the first claiming of the Mount Everest in the Himalaya region of Nepal. Since then, the tourism to reach the highest mountain and have your photo taken there, has become a kind of over-tourism. Spectacular memories and images lead to persons taking unprecedented risks for a bit of fame. 30 persons have died on such expeditions. It is a bit more exclusive than running a marathon of 42,125 km, but even there occasional deaths are part of the race.
Nepal needs the foreign currency to build and rebuild the country. After resources have created the wealth of nations, it is tourist attractions that favour accumulation of wealth. Beware of over-exploiting nature in this respect. The consequences and costs are non-negligable. Climate change does not stop in front of tourist attractions. Some routes in mountains are already more dangerous due to melting of what we named wrongly permanently frozen areas (permafrost). Using virtual reality should allow us rapidly to experience the splendour of the highland Himalaya peaks and climbing. In the meantime enjoy some momo (Himalaya dish) rather than making preparations or training for the next top mountain. It is the images of the area that count, not us in front of the mountains or seemingly endless space. Images and photos taken can help us over the urge to visit this spectacular area ourselves. The planet will need us being satisfied this way, just like watching photos or movies rather than demanding to live in a splendid surrounding or building (castle). My home is my castle and my imagination is my travel book.
