Finding Africa's Lost River Valley

[@ugojlachapelle]

About finding cities, Thebes may add another significant clue. As you have pointed out, it is somewhat located close to the traditional border between the two Lands of Egypt. However, it is also located near the big bend in the Nile River. This bend has made it possible to get fertile land closer together. This in turn made it possible to get more people closer together, making exchange between them more likely, making cities, in turn, more useful for those very exchanges. Why would closer land make it more likely for cities? Because of how transportation works. For most of our history, we've been highly limited in the distance we could cover, and this includes crop transport. Having closer lands at hand meant more crops available closely, meaning more food surpluses handy for the hungry specialized workers found in those cities. So I would add the hypothesis that finding a bend along the river or some other feature that made more fertile land available around a certain location more likely to hold a civilization center. All of this would also explain why all the first major centers would have avoided coastal areas, or, at least, make them smaller. If you have a city along the coast, you cut yourself from half the land you could have used for agriculture to sea. Even if we account for fishing, it doesn't fully compensate for the loss of land, so we'd expect smaller towns along the coast. (The same applies to towns bordering lakes, the Fayyum never became a large city of Ancient Egypt for probably similar reasons.) With a city along a river, you still get the water for drinking, agriculture and transport without sacrificing too much arable land to produce the food needed to maintain the city's population. It's even better with a band as seasonally flooded riverbanks are among the most fertile lands available. Therefore, if I were to look for a location for a population center, I'd look for a place where there's plenty of lowland to be flooded, probably near a bend of that great river, somewhat distant from any significantly large bodies of water.

[@swapanzameen6302]

You explained rise of Calcutta perfectly.

[@ugojlachapelle]

@_____ No, by having more farmland in walking distance. Let's use parcels. If you have three parcels of land following a straight river, the two parcels on either side are separated by the parcel inbetween. If the river bends, the two parcels on either sides can get a lot closer, as the bend forces all parcels to get narrower by the river if we give each parcel equal access to the water. On a larger scale, this makes possible diagonal travel, which reduces distances by about a 30% between areas. This 30% decrease in distance makes it possible to have more farmland within walking distance, therefore making more food available to a fixed location like a city.

[@dr.floridaman4805]

Rivers meander and move. I would bet the city is no longer on the river but far away or even under denile

[@irmaosmatos4026]

@@dr.floridaman4805 In fact, big bends remain practically the same as they were eg. 2k years ago, so finding a big bend of ancient riverbed may still be useful for archeologists

21:59 While the Eye of the Sahara may likely be just a geologic structure and may not have anything there, it is still somewhat interesting that we're talking about potential ancient civilizations in the green Sahara and the Eye just so happens to be relatively close to the old Tamanrasset river bed.

[@raducora7159]

Well, The Eye of Sahara is probably the most plausible location of an actual Atlantis of the past. If that were to be true, it would have most likely gotten it's water from a different source than the Tamanrasset river, but the fact that the monsoon would have gotten more moisture in the Western part of Sahara makes this theory even more plausible.

[@TheMaskedArcanum]

It could possibly have been a religious site. A pilgrimage site for this civilization that was significant enough to be traveled too, despite being in a poor location in terms of a population center.

[@juhonieminen4219]

Richat structure was maybe not a best place to grow crops, but the people living back then might have thought that it was made by gods or by lost human civilization, so they might have build their capital there. Yet they still called themselves atlantians, because of the connection to the sea by rivers and trade.

I’d love a video on what was going on in the Amazon when the Sahara was green. Every discussion of a potentially future green Sahara seems to result in concern that the lack of phosphate kicked up by erosion from Morocco would doom the Amazon.

[@ticksunbs4944]

[@iqmqsd8370]

The Amazon rainforest has been around for 50 million years, and the phosphorus it receives, is mostly from a depression in Chad, not from the coasts of Morocco. Although there is no doubt that a greener Sahara resulted in less dust being blown across the Atlantic, and the recession of the Amazon rainforest, it wasn't a uniform recession, focused mostly on the edges where grasslands and Savannah-like ecosystems spread in place of trees, the core of the jungle was mostly untouched as it has developed its own rainy climate across millions of years that kept the rainforest in a "good shape".

On a somewhat related note, there's an amazing paper which gives an estimated map of global vegetation during the Last Ice Age. According to its findings, the Amazon Rainforest did exist, but was **much** smaller than it is today, and was split into two forests separated by a vast savanna. Though it should be noted that the Sahara was not green during that time-it was just as dry as it is today, and actually a bit larger.

Something to perhaps consider that wasn't mentioned in the video is that given the time scale we're dealing with the river bed as seen today is likely not the same path of the river ten thousand years ago. Doesn't really change much for discussion purposes but the locations of interest may be off by many kilometres. A combination of LiDAR, Radar, and traditional knowledge from the area (If it still exists) could help to narrow down the huge search area. So many cool possibilities!

[@Treviisolion]

Traditional knowledge would be difficult. The only people who might know of anything in that region would be Western Sahara traders who crossed the deserts from Northern Africa to Western Africa. Those trade routes were largely destroyed by the scramble for Africa as big steam boats meant you could carry large amounts of cargo by going around fairly easily, and political divisions meant that travel became harder as it was regulated and European colonialists sought to assert their control over their new dominions. Add on new political instability since decolonization, the relatively small number of traders compared to farmers and any ancient trader knowledge is almost certainly lost, at best leaving only a few stories passed down in a few families, who are unlikely to get in contact with the right people to find clues in these stories.

I've been fascinated by this issue ever since I spent time in the relevant places in my youth. I've stood on "reg" plains in the middle of the Sahara in which you could see millions of fish skeletons, seen sand oceans of dunes hundreds of metres high alternatively swallowing and revealing ancient settlements. Believe me, the territory is so vast, and the conditions (both natural and political) so dangerous, that the amount of scientific archaeology that has been conducted there is insignificant. We still get astonishing surprises, such as the recent discovery of a huge temple complex in Orkney, in places where archaeologists have been combing the land in huge numbers for two hundred years. If we still get big surprises in places you can just pop over to on a one hour ferry ride from Scotland, the surprises in store for us in the Sahara will probably be mind-blowing. The key will always be co-operation with the Tuareg and the Teda, the only people who actually know the desert well enough to survive in it unaided.

Funnily enough there is a really interesting agricultural Saharan civilization that we already know about - although they thrived long after the Green Sahara had faded - the Garamantes. Like the Nabateans they maintained sophisticated systems of water management and built themselves a kingdom on the routes through the Sahara. Unfortunately we don't know a whole lot about them.

@@rogueascendant6611 Should we search for Númenor next, while we are at it? Archeology is about evaluating the probability of where ancient ruins might be and following the leads that are actually useful. We can't just go hunting after every single myth in the world. So let us evaluate how likely Atlantis is to be a real city, let's start with the basic information. Plato claims Atlantis lay directly past the Pillars of Heracles(Straight of Gibraltar) and the mudflats its sinking caused made passage by ship between the Mediterranean and Atlantic impossible. Those are strike one and two for Atlantis being a real city. The location is very clear, and very clearly wrong. Plato furthermore claims Atlantis was the dominant empire of its time, 9000 years before platos time, conquering or subjugating the entire Mediterraine before being defeated by Athens. This Athens, is said by Plato, to have a government that worked exactly like the type of government plato personally idealized, which allowed them to fend of the Super-Empire. Strike 3: The timeframe would squarely place Platos Athen and Atlantis squarely far earlier then most civilisations, with a level of technology far more applicable to Platos time. Strike 4: There is absolutely no hint in any other civilisation of such a Mediterraine Spanning Empire existing, we have found no artifacts of their existence, where we would expect, coinage, weapons, even markers of victories, considering they just subjugated a good part of the known world. Strike 5: The story has a very clear moral, that is perfectly in line with Platos political and spiritual believes. Strike 6: Plato is the earliest mention of Atlantis, and every single other source references him directly or indirectly. (This by itself would not be a good argument, however, considering all the other arguments against Atlantis... it is kinda a final nail in the coffin). Furthermore, there is a civilisation that, under the assumption that Atlantis is a fictional story, is a pretty clear inspiration. Minoa. Expansionist Empire in Conflict with the greek citystates? Massive check. Brought to fall by a natural disaster during one of their strongest times? Check. Plato drew inspirations from the stories of the relatively recent past, to make a political and moral point. There is a reason why most, if not all, credible researches consider Atlantis a myth of fictional entirely.

I hadn't realized that the monsoons associated with the "Green Sahara" originated in the Atlantic (for some reason - maybe because I've only ever heard or thought of the situation in and around Egypt - I'd always assumed it was Mediterranean water vapour that was sucked in over the Sahara by the much warmer temperatures and resulting convection cells over the land). But it does stand to reason that the same phenomenon might also suck even more water vapour into the Western Sahara from the Atlantic. Which raises an interesting question: since the "Green Sahara" was associated with warmer temperatures than today, do any of the climatic models of climate change anticipate a rebooting of "Green Sahara" monsoons at some point? (I don't mean to imply that any such impacts might help mitigate the worse impacts of climate change over the coming century or two - particularly if it's something that could take centuries more or millennia to develop - but it's an interesting property of dynamic systems like the global climate that things don't necessarily move in predictable straight lines and that a hotter world might mean both bigger droughts and desertification in some areas and a contrary trend in others...)

The only problem is that the Garamantes where discovered quite recently and their fortresses can actually be seen by normal satellites, so searching in the middle of the desert would be quite the challenge.

[@greasher926]

Hmm, perhaps Atlantis was an island in the middle of one of those large lakes which were essentially inland seas (like Tenochtitlan) and the river delta was the shoal of mud mentioned that made it impassable? “But afterwards there occurred violent earthquakes and floods; and in a single day and night of misfortune all your warlike men in a body sank into the earth, and the island of Atlantis in like manner disappeared in the depths of the sea. For which reason the sea in those parts is impassable and impenetrable, because there is a shoal of mud in the way; and this was caused by the subsidence of the island.”

[@jjoohhhnn]

Holy crap dude that is an INSANELY HUGE complex! Ty for commenting with the geotag. 10/10 this comment should be pinned. It's over 3 Sq miles with a huge structure in the middle!! Ty SO MUCH for posting this.

[@b22chris]

If only the ancient Egyptians had taken climate change seriously this once prosperous region would still be teaming with life.

[@bernadmanny]

I'm a little disappointed you didn't talk about Giga Chad, or more formally Lake Chad, Giga.

[@mennehgambia1962]

My ancestors, the Serer, were probably there thousands of years ago before being chased down south by fulas, almoravids and arabs coming north with desertification. But there is only evidence that they were north of the Senegal river over 2000 years ago and chased down later, and participated in the Ghana empire. I also think this area was inhabited by Amazighs/Berber people, and the Fulani/Peul people, as we know they were in north west of sahara of tens of thousands of years, including algeria and morocco. Why I think my serer ancestors werent the main inhabitants or even the first of the area is because they are genetically closer to all the other subsaharian west africans, who live in very humid coastal lowlands and have malaria+duffy and other adaptation of more equatorial conditions. However Fulanis and Amazighs both can not only live in drier conditions, but they can also digest milk and starchy foods (amylase and such) much better than all the local tribes, which is a sign of all agricultural peoples of the main ancient civilizations in the great river valleys. My serer ancestors came from the south and arrived in the area some time later. And for anyone trying to say its not true please check the evidence, including genetic before saying things

[@j.p.5013]

Interesting

[@michelangelomissoni945]

Been fantasizing about this for awhile! Same could be said for the Amazon rainforest. Thanks so much for making this great video!

[@wonder_platypus8337]

Always love a new video.

[@localman7017]

Best places to look IMO? The last places to dry up. Look at the basins where there may still have been adequate water after the river mostly stopped being capable of supporting agriculture. When the rivers started drying up these would’ve been the places people fled to.

[@Celis.C]

Giving the rich (human) history of the African continent, I wonder to which degree ancient politics affected any settlement placement in this region. Modern day borders are there to a great extent "thanks to" the Europeans, who knows what territorial claims shaped the history multiple millennia in the past. Fascinating stuff, thanks for sharing!

[@Jabranalibabry]

Fall of Civs shout out is amazing, whoever hasn't checked it out needs to! Absolutely love that podcast; you became Atlas Pro Plus, bro :D

[@westonselna5892]

If you are looking for settlement locations maybe 'the fall line', the farthest place up a river a boat can navigate naturally, might be a good idea.

[@troyward8349]

You might add soil productivity as a factor beyond strategic locations for development to arise, when comparing to the other three civs. This might produce a different set of “x’s”. Maybe locations where the river flowed past mountain ranges which would’ve deposited minerals along the river.

[@rensvanderhoeven9440]

If you had to choose one spot to begin I'd go nearest to the eye of the sahara. I'd was formed millions of years ago by volcanic activity and as we all know here volcanic soil is insanely fertile.

[@oda_margrethe]

This is so interesting! Would love another video on the topic.

[@Dalynx09]

In my opinion there's nothing more beautiful than Africa without the Sahara, but it being a rainforest/jungle/plains instead, Imagine the amount of unknown species there, and how all of history would've changed if the Sahara didn't exist, it's just fascinating

[@dominiquelaflamme7804]

Ever looked into the Richat Structure? It's in Mauritania, right around the places you were exploring.

[@Mojabi_ghost]

Vox just published a very interesting video on how the Amazon rainforest actually supported entire civilizations of indigenous populations despite scientists claiming it to be inhospitable. If anyone is a fan of these “lost civilizations” type of videos I highly recommend you check it out! Anyway, I like your content and would love to see you cover the Amazon next:)

[@auroraedwards4488]

Your best video yet. Using geography to solve an ancient mystery. The possibility of an entirely new civilization still to be discovered. Fascinating!

[@AndresRodriguez-lq1yn]

What about the eye of the Sahara?

[@sharonholdren7588]

I love how you respect geograpy. I always regarded it the queen of the sciences and have a Masters of Geography.

[@aneethasalim5814]

I was watching your video on rainforests, and went on a rabbit hole looking for a proper definition of rainforests, I settled on a definition used by the Indian government for wet evergreen forests which went something like an evergreen or semi evergreen forest which gets more than 1500 mm of precipitation along with a dry wet season of no more than four months, also can you think of any reason why evergreen rainforests are restricted to higher altitudes while the lower reaches are dominated by moist deciduous forests in the Southern Western Ghats mountain range in india while areas with similar precipitation and temperature patterns like northern Vietnam, Northeast India and Mindoro have Lowland rainforests, I'm unable to come up with a convincing reason.

[@AkantorJojo]

Not sure if I understand you correctly, but two things come to mind for me: 1. Latitude: Depending on your distance from the equator (towards the poles) the general wind directions change, and thus the direction evaporated water from the seas gets transported to. 2. Altitude: Rain begins to form when the air is no longer capable of holding all the water it contains as moisture. This is primarily dependant on the temperature of the air (and the pressure). Usually the temperature tends to drop if the air is pushed up a mointainside and thus the mountainsides standing against the winds blowing from a neaby body of water tend to be the regions with most consisten rainfall. So maybe this helps to explain why you find what kind of forest in what region, depending on the geography that influences local climate and weather :D

[@sonjanordahl3158]

Love the cat. Also, it would be interesting if they did lidar scans of the Congo jungle. Now that the Amazon has shown that civilization can develope and flourish in those conditions.

[@jariwouters4095]

Great video as always! This subject in particular intrigues me ever so much as I’ve studied physical geography for the last few years on the University of Utrecht, The Netherlands. In fact, I’ve studied historical meander bends of the Rhine river. I think that it could very well be possible for ancient civilisations to be found along this historical river, perhaps with the use of Digital Elevation Models (DEM’s). Although there is probably not much of this data available, especially when keeping the poor political state in mind. This type of research often result in remarkable findings, even with the littlest of elevation data (e.g. LiDAR data). Interesting topic to think about

[@derianvandalsen]

12:15 And ofcourse the Richat structure makes an appearance

[@PalimpsestProd]

Glad you did a vid on this, have a question. If dust storms in the Sahara act as fertilizer for the Amazon basin, what happened when there were no dust storms because the Sahara was grass and lakes?

[@navexante]

En esos períodos no hubo depósitos de ese polvo en los sedimentos y hoy día se conocen y estudian al detalle, se sabe perfectamente cuando hubo periodos húmedos y cálidos en ese desierto desde hace más de dos millones de años, así que los testigos de esos sucesos hoy día se conocen,

[@aaroniouse]

Interesting how that valley leads right up to the "richat structures"..

[@Iberian_XAVO]

Never thought this would spiral into a discussion about the Western Sahara. I came here really just to learn about the time the Sahara desert was green.

[@QuentinWatt]

The weirdest thing about the map at 6:21 is that if the Sahara was green, I imagine the Arabian peninsula would be green too. Especially if that's where people started growing grains as pointed out. Why is the Arabian peninsula still depicted as a desert?

[@G-rant]

Richat Structure?

[@apostolosvranas4499]

I may not have understood everything but I admire your logic! At the very least, your presentation made sense! As for the political situation, well, it's not only Western Sahara, but Mali, too, that is in a continuous upheaval ... Plus the fact that central state authority does not often extend to all the provinces, some of which are ruled by the local tribes ... Good luck to whomever tries to mount an archaeological expedition there!

[@Vienna3080]

Sometimes relying on Native myths might help, do the Sawhari or Berbers have any myths about some old civilization or people in that area

[@thiernosow11]

you can add the Fulani and the Kanuri to that list

[@TheRainbowDragoness]

As much as I want to listen to this I can't; you're making me sleepy. It's not the subject matter, it's your voice. I find it very relaxing.

[@instantdominator2121]

Imagine if we find a civilization there and then find out that it was actually the first civilization ever.

[@Lilliathi]

We know how the knowledge of agriculture flowed. If anything is there, it would be after Egypt.

[@Prelooker]

Ok, just found your channel, this is the second video I'm watching and you've already got me just by mentioning Fall of Civilizations, 'cause I totally love that channel. BTW, I love how you explain things. I'm super interested in the changes caused by climate and our planet's mechanics. I only wish I could find a video like yours about Sout America about 10K years ago, because I can't find anything on what the Peruvian altiplano was like back then, as to explain how so many sophisticated civilizations were able to thrive in that area.

[@wimprezax]

Everything you described points to the Eyes of Sahara, and I thought you were going to say that it is the perfect place for a city. This is exactly what Jimmy at Bright Insight has been trying to point out. The Atalantis.

[@yonatanshm9353]

I particularly liked the Nabataen episode, so interesting, thanks for showing the podcast to us
