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!

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.
