Damming the Mediterranean: the Atlantropa Project
Did we miss a utopia or avoid a disaster?
Herman Sörgel’s Atlantropa is the craziest, most megalomaniacal scheme from the 20th century that you never heard of.
Sörgel (1885-1952) was a renowned German architect of the Bauhaus school, and a philosopher reflecting on culture, space and geopolitics. On the future’s horizon, he saw the emergence of three global superpowers, one uniting the American continent, another a Pan-Asian block, and Europe – possibly the weakest of the three.
His solution was to engineer Europe out of its problems. Sörgel based his solution for Pan-European power and self-sufficiency on the observation that, although significant amounts of water flow into the Mediterranean through the Strait of Gibraltar (from the Atlantic Ocean) and the Dardanelles (from the Black Sea), its level stays the same, through evaporation. Hence his proposal to dam the Mediterranean at both ends, using the reduced inflow to generate massive amounts of hydroelectricity (110,000 Megawatt via several dams, of which 50,000 MW via the Gibraltar dam alone) and in the process create new land, which not only could be used for colonisation, but would also connect Europe to Africa. Thus would be created a new supercontinent, Atlantropa (giving the former easy access to the latter’s raw materials).
Sörgel first publicised his ideas in his 1929 book Mittelmeer-Senkung, Sahara-Bewässerung, Panropaprojekt (‘Lowering the Mediterranean, Irrigating the Sahara: the Panropa Project’), reiterating and specifying them in Atlantropa (1932). Later versions of the project included plans to create a series of giant lakes in Central Africa (Sörgel’s father, significantly, pioneered hydroelectricity in Bavaria).
Atlantropa ‘part one’
Sörgel, a pacifist, had noble motives and his ideas were not without merit, but the logistics of the project were daunting. He saw cheap hydroelectricity as the answer to a future in which non-renewable energy sources such as coal, gas and oil would dwindle to depletion; he thought colonising new lands in the Mediterranean would give European nations a positive focus towards cooperation and help avoid another war. The growth of industry and agriculture would thus be safeguarded. And the land reclamation of parts of the Mediterranean seafloor would mirror, on a much larger scale, the centuries-old communal struggle of Holland against the North Sea. It would also provide another outlet for Napoleon’s vision of forging a peaceful European Union through the joint colonisation of Europe’s East (an idea no doubt constructed to help justify Napoleon’s Russia campaign of 1812). The massive works would go on for more than a century, eliminating unemployment for generations.
But consider what was to be the lynchpin of Atlantropa, the Gibraltar dam. At its narrowest, the Strait of Gibraltar is 14 km (9 mi) wide. And yet, for some reason, Sörgel decided the dam should be built 30 km further inside the Mediterranean, where it would have to be significantly longer. The foundations for the dam would have to be 2.5 km wide, and 300 m high. It would take 10 years to complete, and 200,000 workers labouring in 4 continuous shifts. The dam would be crowned by a 400-meter high tower. Calculations at the time cast doubt on whether there would be enough concrete in the world to complete the gargantuan project.
And consider what would happen to the Mediterranean, cut in two by the lower sea levels, with Sicily connected to both Tunisia and the Italian mainland (allowing, among other things for a regular train service between Berlin and Cape Town). In the western half, the water would be lowered by 100 meters, in the eastern half by as much as 200 meters, combining to create 576,000 km2 new dry land, a fifth of the Mediterranean’s surface, or more than the surface of Belgium and France combined. Imagine the problems and traumas this would create for coastal cities such as Marseille or Genoa. Sörgel did propose the construction of new harbours, and did provide a special solution for Venice: another dam would safeguard its lagoon from drying out. But that lagoon would be a lake, 500 km away from the nearest seashore.
Sörgel’s plan would be considered outdated today for more reasons than just its megalomania. It was also completely eurocentric, proposing a Euro-African continent entirely run by and for the benefit of Europe(ans), Africa(ns) being reduced to supplying raw materials (Sörgel saw a strong Atlantropa, also controlling the Middle East, as a bulwark against the ‘Yellow Peril’). Furthermore, there was totally no regard for its ecological impact: the increased salinity of the remaining Mediterranean Seas would have killed off much of the flora and fauna, the precipitation patterns could shift dramatically. And one shudders to think what would happen if the giant Gibraltar dam would be breached by a tsunami, an earthquake or a terrorist attack.
Atlantropa ‘part two’
Despite his pacifist leanings, Sörgel attempted to reformulate his ideas in a way more favourable to the national-socialist world view. In 1938, he wrote Die drei grossen A: Amerika, Atlantropa, Asien – Grossdeutschland und das italienisches Imperium, die Pfeiler Atlantropas (‘The Three Big A’s: America, Atlantropa, Asia – Greater Germany and the Italian Empire, the Pillars of Atlantropa’), and in 1942 the equally Lebensraum-ish Atlantropa-ABC: Kraft, Raum, Brot (‘Atlantropa ABC: Strength, Space, Bread’).
Sörgel’s ideas never caught on with the Nazis, whose expansionist plans were oriented more towards the East than towards the South. The idea therefore survived the Second World War, but was eventually rendered moot by the advent of nuclear power and the end of colonialism. Sörgel kept defending his ideas literally to the death: in 1952, he was hit and killed by a car while biking to hold a speech on his Atlantropa project, the dream of which died a slow death after his own. In 1960, the Atlantropa Institute was closed.
Although Atlantropa never came close to realisation, or maybe because of it, the concept did gain some currency in science fiction circles. A few examples:
Thanks to Marc Itschner and Sebastian Castañiza for informing me of the Atlantropa project and of this map (in German), showing its Mediterranean component, which can be found on the relevant Wikipedia page. It shows (in the upper left corner) Venice, connected via a canal to the Mediterranean, and (in the upper right corner) the Sea of Marmara with dam and power station, (in the lower left corner) the main dam and power station at Gibraltar, (in the lower middle of the map) a second dam at Sicily to facilitate the differentiated lowering of the eastern Mediterranean’s sea level and (in the lower right corner) an extension of the Suez Canal. The legend indicates planned rail links, planned irrigation areas through desalinisation plants, and amount of land reclaimed (in kilometers).
The second map of the ‘African’ part of the project can be found here, on a page called Xefer. It shows the African interior dominated by a few huge, artificial lakes: Lake Chad hypertrophied into the Chad Sea, reaching deep into the Sahara, its overflow connected to the Mediterranean, but also connected via the Ubangi Overflow to a titanic Congo Lake, created by damming the Congo River and flooding most of Congo’(s interior.

New anthropological research suggests our ancestors enjoyed long slumbers.
- Neanderthal bone fragments discovered in northern Spain mimic hibernating animals like cave bears.
- Thousands of bone fragments, dating back 400,000 years, were discovered in this "pit of bones" 30 years ago.
- The researchers speculate that this physiological function, if true, could prepare us for extended space travel.
Humans have a terrible sense of time. We think in moments, not eons, which accounts for a number of people that still don't believe in evolutionary theory: we simply can't imagine ourselves any differently than we are today.
Thankfully, scientists and researchers have vast imaginations. Their findings often depend on creative problem-solving. Anthropologists are especially adept at this skill, as their job entails imagining a prehistoric world in which humans and our forebears were very different creatures.
A new paper, published in the journal L'Anthropologie, takes a hard look at ancient bone health and arrives at a surprising conclusion: Neanderthals (and possibly early humans) might have endured long, harsh winters by hibernating.
Adaptability is the key to survival. Certain endotherms evolved the ability to depress their metabolism for months at a time; their body temperature and metabolic rate lowered while their breathing and heart rate dropped to nearly imperceptible levels. This handy technique solved a serious resource management problem, as food supplies were notoriously scarce during the frozen months.
While today the wellness industry eschews fat, it has long had an essential evolutionary function: it keeps us alive during times of food scarcity. As autumn months pass, large mammals become hyperphagic (experiencing intense hunger followed by overeating) and store nutrients in fat deposits; smaller animals bury food nearby for when they need a snack. This strategy is critical as hibernating animals can lose over a quarter of their body weight during winter.
For this paper, Antonis Bartsiokas and Juan-Luis Arsuaga, both in the Department of History and Ethnology at Democritus University of Thrace, scoured through remains of a "pit of bones" in northern Spain. In 1976, archaeologists found a 50-foot shaft leading down into a cave in Atapuerca, where thousands of bone fragments have since been discovered. Dating back 400,000 years—some of the fragments may be as old as 600,000 years—researchers believe the bodies were intentionally buried in this cave.
Evidence of ancient human hibernation / human hibernation for space travel | Dr Antonis Bartsiokas
While the fragments have been well studied in the intervening decades, Arsuaga (who led an early excavation in Atapuerca) and Bartsiokas noticed something odd about the bones: they displayed signs of seasonal variations. These proto-humans appear to have experienced annual bone growth disruption, which is indicative of hibernating species.
In fact, the remains of cave bears were also found in this pit, increasing the likelihood that the burial site was reserved for species that shared common features. This could be the result of a dearth of food for bears and Neanderthals alike. The researchers write that modern northerners don't need to sleep for months at a time; an abundance of fish and reindeer didn't exist in Spain, as they do in the Arctic. They write,
"The aridification of Iberia then could not have provided enough fat-rich food for the people of Sima during the harsh winter—making them resort to cave hibernation."
The notion of hibernating humans is appealing, especially to those in cold climates, but some experts don't want to put the cart before the horse. Large mammals don't engage in textbook hibernation; their deep sleep is known as a "torpor." Even then, the demands of human-sized brains could have been too large for extended periods of slumber.
Still, as we continually discover our animalistic origins to better understand how we evolved, the researchers note the potential value of this research.
"The present work provides an innovative approach to the physiological mechanisms of metabolism in early humans that could help determine the life cycle and physiology of extinct human species."
Bartsiokas speculates that this ancient mechanism could be coopted for space travel in the future. If the notion of hibernating humans sounds far-fetched, the idea has been contemplated for years, as NASA began funding research on this topic in 2014. As the saying goes, everything old is new again.

It is impossible for science to arrive at ultimate truths, but functional truths are good enough.
- What is truth? This is a very tricky question, trickier than many would like to admit.
- Science does arrive at what we can call functional truth, that is, when it focuses on what something does as opposed to what something is. We know how gravity operates, but not what gravity is, a notion that has changed over time and will probably change again.
- The conclusion is that there are not absolute final truths, only functional truths that are agreed upon by consensus. The essential difference is that scientific truths are agreed upon by factual evidence, while most other truths are based on belief.
Does science tell the truth? The answer to this question is not as simple as it seems, and my 13.8 colleague Adam Frank took a look at it in his article about the complementarity of knowledge. There are many levels of complexity to what truth is or means to a person or a community. Why?
First, "truth" itself is hard to define or even to identify. How do you know for sure that someone is telling you the truth? Do you always tell the truth? In groups, what may be considered true to a culture with a given set of moral values may not be true in another. Examples are easy to come by: the death penalty, abortion rights, animal rights, environmentalism, the ethics of owning weapons, etc.
At the level of human relations, truth is very convoluted. Living in an age where fake news has taken center stage only corroborates this obvious fact. However, not knowing how to differentiate between what is true and what is not leads to fear, insecurity, and ultimately, to what could be called worldview servitude — the subservient adherence to a worldview proposed by someone in power. The results, as the history of the 20th century has shown extensively, can be catastrophic.
Proclamations of final or absolute truths, even in science, shouldn't be trusted.
The goal of science, at least on paper, is to arrive at the truth without recourse to any belief or moral system. Science aims to go beyond the human mess so as to be value-free. The premise here is that Nature doesn't have a moral dimension, and that the goal of science is to describe Nature the best possible way, to arrive at something we could call the "absolute truth." The approach is a typical heir to the Enlightenment notion that it is possible to take human complications out of the equation and have an absolute objective view of the world. However, this is a tall order.
It is tempting to believe that science is the best pathway to truth because, to a spectacular extent, science does triumph at many levels. You trust driving your car because the laws of mechanics and thermodynamics work. NASA scientists and engineers just managed to have the Ingenuity Mars Helicopter — the first man-made device to fly over another planet — hover above the Martian surface all by itself.
We can use the laws of physics to describe the results of countless experiments to amazing levels of accuracy, from the magnetic properties of materials to the position of your car in traffic using GPS locators. In this restricted sense, science does tell the truth. It may not be the absolute truth about Nature, but it's certainly a kind of pragmatic, functional truth at which the scientific community arrives by consensus based on the shared testing of hypotheses and results.
What is truth?

But at a deeper level of scrutiny, the meaning of truth becomes intangible, and we must agree with the pre-Socratic philosopher Democritus who declared, around 400 years BCE, that "truth is in the depths." (Incidentally, Democritus predicted the existence of the atom, something that certainly exists in the depths.)
A look at a dictionary reinforces this view. "Truth: the quality of being true." Now, that's a very circular definition. How do we know what is true? A second definition: "Truth: a fact or belief that is accepted as true." Acceptance is key here. A belief may be accepted to be true, as is the case with religious faith. There is no need for evidence to justify a belief. But note that a fact as well can be accepted as true, even if belief and facts are very different things. This illustrates how the scientific community arrives at a consensus of what is true by acceptance. Sufficient factual evidence supports that a statement is true. (Note that what defines sufficient factual evidence is also accepted by consensus.) At least until we learn more.
Take the example of gravity. We know that an object in free fall will hit the ground, and we can calculate when it does using Galileo's law of free fall (in the absence of friction). This is an example of "functional truth." If you drop one million rocks from the same height, the same law will apply every time, corroborating the factual acceptance of a functional truth, that all objects fall to the ground at the same rate irrespective of their mass (in the absence of friction).
But what if we ask, "What is gravity?" That's an ontological question about what gravity is and not what it does. And here things get trickier. To Galileo, it was an acceleration downward; to Newton a force between two or more massive bodies inversely proportional to the square of the distance between them; to Einstein the curvature of spacetime due to the presence of mass and/or energy. Does Einstein have the final word? Probably not.
Is there an ultimate scientific truth?
Final or absolute scientific truths assume that what we know of Nature can be final, that human knowledge can make absolute proclamations. But we know that this can't really work, for the very nature of scientific knowledge is that it is incomplete and contingent on the accuracy and depth with which we measure Nature with our instruments. The more accuracy and depth our measurements gain, the more they are able to expose the cracks in our current theories, as I illustrated last week with the muon magnetic moment experiments.
So, we must agree with Democritus, that truth is indeed in the depths and that proclamations of final or absolute truths, even in science, shouldn't be trusted. Fortunately, for all practical purposes — flying airplanes or spaceships, measuring the properties of a particle, the rates of chemical reactions, the efficacy of vaccines, or the blood flow in your brain — functional truths do well enough.
Using urinals, psychological collages, and animated furniture to shock us into reality.
- Dada is a provocative and surreal art movement born out of the madness of World War I.
- Tzara, a key Dada theorist, says Dada seeks "to confuse and upset, to shake and jolt" people from their comfort zones.
- Dada, as all avant-garde art, faces a key problem in how to stay true to its philosophy.
In a world gone mad, what can the few sane people left do? What can someone say when there are no words that seem up to the job? How can anyone hope to express ideas so terrible when doing so will only reduce those ideas?
These are some of the things that inspired the Dada movement, and in its absurd, surreal, and chaotic nonsense, we find the voice of the voiceless.
The origin of Dadaism
Dada was a response to the madness of World War I. Reasonable, intelligent, and sensitive people looked at the blood and mud graveyards of the trenches and wondered how any meaning or goodness could ever be found again. How can someone make sense of a world where millions of young, happy, hopeful men were scythed down in a spray of bullets? How could life go back to normal when returning soldiers, blinded and disfigured from gas, lay homeless in the streets? Out of this awful revulsion, there came one bitter voice, and it said: "Everything is nonsense."
Dada is the art of the nihilist. It smashes accepted wisdom, challenges norms and values, and offends, upsets, and provokes us to re-examine everything.
And so, the Dada movement expressed itself in absurdity. Tzara, the closest you get to a Dadaist philosopher, put it like this: "Like everything in life, Dada is useless. Dada is without pretension, as life should be." Dada rejects all systems, all philosophy, all definite answers, and all truth. It is the living embrace of contradictions and nonsense. It seeks "to confuse and upset people, to shake and jolt". It aims to shout down the "shamefaced sex of comfortable compromise and good manners," when actually "everything happens in a completely idiotic way."
In short, Dada is a response to the world when all the usual methods have broken down. It's the recognition that dinner party conversations, Hollywood blockbusters, and Silicon Valley are not how life actually is. This is a false reality and order, like some kind of veneer.
The Dada response to life is to embrace the personal and passionate madness of it all, where "the intensity of a personality is transposed directly, clearly into the work." It's to recognize the unique position of an artist, who can convey ideas and feelings in a way that goes beyond normal understanding. Art goes straight to the soul, but the intensity of it all can be hard to "enjoy" in the strictest sense.
Where is this Dada?
For instance, Dada is seen in the poems of Hugo Ball who wrote in meaningless foreign-sounding words. It's in Hausmann, who wrote works in disconnected phonemes. It's found in Duchamp's iconoclastic "Fountain" that sought to question what art or an artist really meant. It's in Hans Richter's short film "Ghost before Breakfast," which has an incoherent montage of images, loosely connected by the theme of inanimate objects in revolt. And, it's in Kurt Schwitters' "psychological collages" which present fragments of objects, juxtaposed together.
Dada is intended to shock. It's an artistic jolt asking, or demanding, that the viewers reorient themselves in some way. It is designed to make us feel uncomfortable and does not make for easy appreciation. It's only when we're thrown so drastically outside of our comfort zone in this way that Dada asks us to question how things are. It shakes us out of a conformist stupor to look afresh at things.
The paradox of Dadaism
Of course, like all avant-garde art, Dada needs to address one major problem: how do you stay so provocative, so radical, and so anti-establishment when you also seek success? How can maverick rebels stay so as they get a mortgage and want a good school for their kids? The problem is that young, inventive, and idealistic artists are inevitably sucked into the world of profit and commodity.
As Grayson Perry, a British modern artist, wrote: "What starts as a creative revolt soon becomes co-opted as the latest way to make money," and what was once fresh and challenging "falls away to reveal a predatory capitalist robot." With Dada, how long can someone actually live in a world of nonsense and nihilistic absurdity?
But there will always be new blood to keep movements like Dada going. As the revolutionaries of yesterday become the rich mansion-owners of today, there will be hot, young things to come and take up the mantle. There will always be something to challenge and questions to be asked. So, art movements like Dada will always be in the vanguard.
Dada is the art of the nihilist. It smashes accepted wisdom, challenges norms and values, and offends, upsets, and provokes us to re-examine everything. It's an absurd art form that reflects the reality it perceives — that life is nothing more than a dissonant patchwork of egos floating in an abyss of nothing.
