Desertification

Since 2018 we have evidence of the progression of desertification into some Member States of the European Union. The mediterranean countries are concerned as well as regions of Bulgaria and Romania near the Black Sea. There are multiple sources of desertification. The 3 main reasons of desertification are soil erosion, loss of soil fertility and loss of natural and desirable vegetation besides wind or water erosion and salinization. We also know that man-made climate change is at the root of the past and recent problems. The statistical indicators of land degradation are collected by the European Joint Research Centre and these data show a dismal picture of land degradation in general and desertification as part of this process. A study by Ilea et al. published in Nature 2024 projects an intensification of extreme weather in the coming years. Higher temperatures will most likely enhance desertification and more frequent flooding will contribute to more soil erosion as well. It is a rather strange process that we know we are creating severe problems for some regions which endanger the roots of their existence and yet we do not act upon those undeniable facts (United Nations SDGs list). The amount and dynamics of land deterioration put the global South under severe pressure, but also the wealthy parts of the Mediterranean basin will be affected. It about time to acknowledge that we are all part of the global changes and challenges. (Image palm tree in Paris, Jardin du Luxembourg, 2024)

Games over

All nice things eventually come to an end. So do the Paris 2024 Olympics and Paralympics.
The images have been impressive of both events and the millions of spectators give a good testimony in this respect. The cultural by-program of the Games was equally remarkable. The live performances of dancers not only on the opening and closing ceremonies attracted big audiences. Many well-known sites of Paris prepared their own events and inspired as well as entertained the visitors.
On the small stage in front of the “Marie de Paris”, the city hall (Image below), ballet performances (video) were staged to hint at the possibility to see more artistic performances throughout the year in Paris opera houses and other stages.
Showcasing many forms of cultural, inspiring and entertaining events gave a valuable additional flavour to the Paris Olympics. Many good reasons to come back and renew unique moments in Paris beyond 2024. Paris hotels will be more accessible again for moderate budgets and waiting times for entries should come down to normal levels as well. Back to a new normal for Paris. Well, maybe. The millions of spectators who followed the Games on television and social media might eventually decide to rank Paris higher in the “cities you have to go to at least once in your lifetime”.

Lost Objects

Project yourself into the future more than a hundred years from today, maybe even more than a thousand years from today. Some archaeologists will work on the planet earth to uncover the story behind the disappearance of the once very advanced species of homo erectus. They start drilling near some of the mystical sites of this civilization, the cities where mass celebrations were held called Olympic Games. These archaeologists use huge drilling machines to take samples at previous Olympic sites and uncover the remains of the thought to be modern civilizations on earth. Amongst all these samples they find all sorts of artifacts and layers left over. Plastics and metal structures appear in the samples as well as other forms of „artificializations“, transformations of earth’s principal „natural“ raw materials. The inhabitants of earth apparently lost or destroyed the planet‘s capabilities of CO2 storage and eventually became extinct. After fighting for survival on another planet the archeological expedition on earth saved this block of the remains of a doomed civilization. All this is pure science fiction, yet the specimen sample is exposed on the roof of the futuristic Fondation Louis Vuitton building near the Jardin d‘Acclimatation in Neuilly sur Seine.

Olympic Criticism

The Olympic Games are, like every international organization, subject to criticism. In democracies this is part of the DNA of democracies that you can voice your criticisms openly without being threatened by persecution or arrest. The Olympic Games have since its beginning in ancient or modern times favored sport disciplines that have a link to warfare. The spectrum of disciplines has been extended recently to blur a bit this belligerent image of the Games. However even the break dance is performed in a kind of battle or competition between two adversaries. This is the reason why totalitarian states have (had) a predilection to show off their state sponsored warriors in the Olympic Games. Nazi Germany and the Berlin 1936 Games were the worst example of how the Games can get abused only to demonstrate a country’s force through athletes. Dictatorships of our times are not much different in this regard. Showing how many successful athletes (soldiers) you are able to produce is somehow an indicator of your professional training system of elite performance. Now, add to it the top performance in the Paralympic Games like Paris 2024 and you can even demonstrate how well you are able to care for and train potentially even also for mutilated warriors. Criticism of preparations of warriors and war masked through sport competitions are maybe unfair or utterly displaced here. It is, nevertheless, much better to compete on the sports-field rather than with loaded weapons. Only in retrospect, we often understand, why some nations made such enormous efforts to demonstrate a commitment to win as much as possible. With a growing enthusiasm for the Olympic Games the critical reflections rise as well.

Paralympic Counting

The classification system of the Paralympic disciplines is well worked out. This ensures that competitions are on a more equal footing. The counting of medals, points and penalties is an easy task. It is more difficult to keep track of equipment and infrastructure and the adaptation status of it to Paralympic needs in a country or region. Statistics and monitoring of installations is one important step in preparing for participation and success in Paralympic disciplines. On an European open data platform we find the regional data set of “Parasportive equipment in clubs and committees of the Pays de la Loire”, for example. Transparency of structures is a first step in improving access to it. For Paralympic athletes it is the same process to gain access to sport equipment as for all other athletes. The monitoring of infrastructure and equipment is a laborious task, but the documentation of helps people on their way to obtain access. Paralympic counting, therefore, is much more than counting medals and trophies even if they are really nice looking.

Olympic Medals

The distribution of Olympic medals across continents reveals the persistent inequality of rewards across the globe. The first African country in the overall ranking of countries by Olympic medals is Kenya on 17th place. All 11 medals including 4 gold medals were obtained in athletics and in running disciplines 800m and more. The financial resources needed to practice running as high level sport are probably the lowest one of all disciplines. Ethiopia is another African country with this tradition of high level long distance runners on the African continent. Equipment and coaching in other disciplines than athletics involves more infrastructure and becomes more costly and the possibility to reserve infrastructure for elite athletes of a country is more difficult if the infrastructure for the population at large is rather limited compared to the population size. Therefore, the Olympic tradition has to confront the challenge of unequal access to many disciplines of the Olympic Games also in Paris 2024. Being a very good athlete is just not enough if you lack the coaches, training and facilities to be able to compete with the well-equipped countries. The knowledge about the best details of a specific technique or optimization potentials are part of the Olympic challenges as well. The Americas, Europe and Asia might be confronted with new forms or another criticism of imperialist strategies, this time in the domain of sport. The winner or medalists take all. Country rankings appear a bit like the football device “money buys goals”. (Image, Fondation Louis Vuitton, Paris, Extrait of Omar Victor Diop “Diaspora” 2014-2015).

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.

Olympics for All

The Paris 2024 Olympic Games and the Paralympic Games have demonstrated the extraordinary competence, professionalism and competitiveness of all athletes. The television spectators and live participants in the events have been involved to a great deal.
After all this hype around sports let us consider the probability of getting involved in physical activities and sports. Additionally, it is of interest, whether people are encouraged to continue sports, maybe at higher ages as well through these sports events like Olympia.
High level athletes are most likely to continue their sports activities. In many countries the extraordinary athletes of the Paralympics faced tough challenges to pursue their sport interests and passion.
However, the public health challenge is the big unresolved issue of how to best raise an awareness for the pleasures and benefits of sport for the masses. (bibliography by BNF “Santé et activité physique). It is not only a matter of suitable infrastructure, but also the question of sports in your neighbourhood. This issue has implications for urban and rural communities and how they organize the practice of sports in an inclusive way. Each step may be a stepping stone into sports for all ages and pathologies.
The pleasure and benefit to walk or something simple as walking to or walking after work, are part of the solution to many public health issues.
The visitors of the Paris Olympics walked a lot.
This fun experience in an enthusiastic city will encourage many to continue the simple exercise without thinking about exercise. This will do the trick. Just do it, without thinking to much about it.

Burden of Disease

For the planning of health and care systems it is important to measure the so-called burden of disease within societies or related to specific diseases or social groups. A large-scale analysis of several longitudinal data bases of the populations 50 years of age and older shows that we have underestimated the burden of disease to societies of psychiatric disorders, like depression, in most societies.
A meta-study and overview of previous studies showed already that depression (age 60+) is more common in lower-income countries (between 25 and 33% of 60+population age group). High income countries, studied by Wang et al. 2024 in The Lancet Healthy Longevity, have rates of depression well below these levels, but a link to socioeconomic status, inactivity and loneliness is still evidenced. A five-year follow-up of persons aged 50+ years shows that the probability to develop a depression (hazard rate) is twice as high for persons with low socioeconomic status, who were socially
inactive and lonely than for socially active, high socioeconomic status and did not feel lonely at the beginning of measurement. The conclusion of the research highlights the need to develop and implement integrated and simultaneous initiatives to addressed the growing burden of disease related to depression in older persons.

Alzheimer Research

Alzheimer disease has reached unprecedented levels in line with population aging. The study by Martino-Adami et al. 2024 has raised the hope that more people can receive an early diagnosis of Alzheimer and potentially start treatments. The study used plasma biomarkers rather than much more expensive and rare MRI scans for diagnosis. The rather exceptional results allow even to test for severity of Alzheimer according to established evaluation measures. Additionally, the probability of an Alzheimer trajectory on a time scale is feasible. The authors suggest that the data and statistical methods applied allow to identify Alzheimer before the outbreak of impairments. The data sample stems from “patients of advanced age visiting primary care”. This remains a limitation for generalizations, but the hope that other studies test the same approach with samples from younger populations will spur additional investments into such research. The list of institutions and foundations that contributed to make this study possible is really long. Thanks go to all involved, researchers, donors as well as the reviewers and editors of the journal. (Image Paris Metro Help Column 2024)
