I can't believe a full team of geographers didn't know these were water retention thingies. These are fairly common. They are used widely parts of Africa and Asia and they have been talked about a fair bit in many types of media.
I'd even heard of these on youtube from at least one channel - dust ups by shaun overton! He's doing these in a tx desert to capture rain. Cool video, and fun for me (and probably many others) that I knew what these were right away!
As an Iranian, I wanna say thank you for making this video. There have always been a large variety of ancient methods for water reservation in different regions of Iran and each region usually has its own technique. Unfortunately, not all of these techniques have been recorded or they're not always readily available or are being forgotten. Also if you need help with finding research papers in Persian or Korean, I could be of help. :)
I recognized those marks right away. Here in the western ghats of India, we have been making these bunds for a long time too. These are generally restricted to sides of dry mountains and sloping unfarmed lands. They help immensely in increasing the water table and stopping erosion. If you are interested, I can send you some images of these build on my own farmland along with more details about different variations of these that we use.
Hello from Iran! I particularly enjoyed your conclusion at the end of the video. However, the harsh reality is that these projects used to be the starting point for much larger endeavors that are now abandoned due to insufficient funding.
I love how this feels very much like a continuation of his earlier investigation for Vox figuring out what these circles were in the Algerian desert, remnants of exploration by the French colonists prospecting with dynamite blasts (well worth the watch if you haven't seen it!). I hope people send Christophe more satellite mysteries to look into, and that it becomes a series. I can already see it, "in the next episode: who drew these triangles in the Gobi desert?"
Thank you, Cristophe for this amazing content on TH-cam. You work on Vox always struck a chord, and now, seeing you do the same kind of rigorous and vigorous work really makes me happy. Keep it up. Regards One of your admirers
Good video! I've seen few permaculture videos so for once I actually had some clue as to what was going on. Keep up the good work, you make some of the best videos on this website!
You said in your pilot video that everyone can do the research, I googled half-moons and I found exactly what they were, but is not the same when you explain it with details
Haven't watched yet so here's my guess. The crescent shapes are meant to capture water flowing across the surface and let it sink in promoting water retention for desert reclamation projects.
Given how common these seem to be in severely water-stressed areas across the world, I’m surprised you couldn’t have just done a reverse image search on the original bunds themselves…but that wouldn’t have made for such a fascinating and compelling video. Brilliantly executed and edited. Great audio, too. And the French was a cool touch! Explains the missing ‘r.’
Funny enough my very first thought when I saw the shapes was that they were water conservation rings, there have been great strides made to prevent desertification in sub-Saharan Africa using these trenches.
Nice video! Great to see something weird expained. I like you do to a video on the Richat Structure. Obviously there are a lot of conspiracy theories about it, but on top of that it would be great to have a proper explanation and some more Worldly or even other worldly examples of the same thing.
I've just seen the markings in the video so decided to leave a comment. If you've been to one of the Canary Islands you'll find these shapes here for growing grapes and they are there to capture water. Lets see if I got it with zero research other than a holiday in the Sun. I'll be back to edit this comment after I've watched the video in full. EDIT: lol, nailed it! Moral here is travel more with your eyes open :)
The instant I saw the start of this video It reminded me of the video that I saw with them trying to reverse desertification using methods similar to this in Africa.
10:00 - Hah no way! That was exactly what I initially though it would be, since TH-cam pushed a video to me showing the project in African trying to combat the deserts.
when the half moons were brought up, it immediately ticked with me what they were for having watched a video on combatitng desertification in places like the Sahel and western India
As an Iranian, I feel that the Iranian government does not care about this part of the country and for some reason does not want to develop this region.
I wonder if Andrew Millison knows any more about this. He is an expert on permacultures and works on landscape scale restorative projects all around the world including India and the Green Wall project that is being worked on by North African nations in the Sahel. There they do a lot of those smaller half moons. But he might also know more about the contouring project in Iran?
It was almost immediately obvious to me that these were some kind of groundwater control system. I may be watching Andrew Millison too much. But yep, why else would you do something so extensive and seemingly following contours of the earth. However, they were too big. I am used to the small ones. But, I was happy to have my guess be fleshed out. I am a fan of this channel. @aKenyanChatter
Pskov is a city in Russia, a relatively large one at that, and nothing to do with this Iranian village. Google Translate might have decided to translate the Farsi word containing a similar string of sounds to that mistakenly because it recognises that city name but not this small village.
I made a screen of these and showed to chat gpt and asked him about it. It answered me in few seconds and told everything that is in this video. Im not saying that you are useless. Your videos are very entertaining ❤
I loved this, thank you!!! Wondering why we don't try this in our western desert/arid areas...oh, that's right, people in our country think government is a waste of their $.
No doubt that climate change has played a role but it’s also a prime example of how a country knowingly let this happen, as someone from Baluchistan, it’s not the only worse thing happened to our motherland but sadly I won’t even say much due to consequences that I can face. The video was very engaging but I am shocked to see how you couldn’t recognize what these were given how common they are.
This was an easy question to answer if you know anything about sub-Saharan Africas "Great Green Wall". It is a long term project to stop the Sahara from growing into the Sahel region. Bottom line; they work!
Jhony Haris promoted this channel, so they are probably working together on videos. Also the music is done by Tom Fox. Both channels use his music as you can see at the end of the video credits.
I'm a little surprised and skeptical about your findings in this video. Are these contour bunds really efficient? In all the pictures they seem to be completely dried out. If they were efficient, there should be some vegetation growing, or some darker area where the water is being held back, I guess.
This was great and makes me wonder about the agricultural hub in the southern US, around the Colorado river. Massive area of crops in the desert. Most of this is in California, and last I heard, they did not agree to ration water usage from the river. Climate change + water rights talks? I’ll start digging some contour bunds 😢
It's definitely completely unrelated but... Those patterns look so similar to the lens effect i saw during the Total Solar Eclipse in Oregon. It covered stuff with so many crescent moon shaped shadow patterns
While prod. quality is high, but content wise? Seriously no geo. ppl knew what these are? CMON man same is happening at search party: nice images but meh stories Tunnel Vision ha!
I found this very interesting, informative and well done, enough for me to subscribe. I also believe in the Bible and God has other plans for this world and even with all of mankinds efforts man will not be saving this planet, maybe you should research that. 🙂👍
As someone who lives in Iran this video made me so happy! thank you 🥹✨ if you need any other help regarding your future research let me know i would love to help ✨

This channel's production quality is so good. I feel like I am part of the investigation. Well done, Christophe and team.
I can't believe a full team of geographers didn't know these were water retention thingies. These are fairly common. They are used widely parts of Africa and Asia and they have been talked about a fair bit in many types of media.
I can't believe the guy that actually knows what they are calls them thingies 😂
academia only teaches about the tools and technologies of the colonizers.

Never stop making videos about crazy google earth mysteries Christophe
oooh your videos are great too!

Johnny created a MONSTER he can't even stop
"This might be a completely useless rabbithole." A typical work day for Christophe
The way you investigate these kind of topics makes me want to do the same. You’re an inspiration
Love the channel, just one question, why is the channel's name Christophe instead of Tunnel Vision? xD
probably branding reason
incredible content! makes the whole research process feel very approachable. can't wait to see where this channel goes.
If video editing quality had a definition in the dictionary, Christophe would appear as an example of it. Breathtaking talent.
Hello from Iran! I particularly enjoyed your conclusion at the end of the video. However, the harsh reality is that these projects used to be the starting point for much larger endeavors that are now abandoned due to insufficient funding.
This is some really good research. Thank you very interesting and informative
what's great about you Christophe is you make something which is in itself boring, incredibly interesting and engaging! :D
Always an exciting moment when YT notifies me that you have released a new video. Great job, journalism at it's best.
Yay! Another rabbit hole!!
Watching from the Philippines! Insightful content as always.
I love how this feels very much like a continuation of his earlier investigation for Vox figuring out what these circles were in the Algerian desert, remnants of exploration by the French colonists prospecting with dynamite blasts (well worth the watch if you haven't seen it!). I hope people send Christophe more satellite mysteries to look into, and that it becomes a series. I can already see it, "in the next episode: who drew these triangles in the Gobi desert?"

Just beautiful. I love learning this way!
Thank you! You taught me something about my country that I didn't know!
Appreciate your work! Keep it up!❤
Was waiting for your next vid 😌
Another Vox journalist starting on their own and giving us incredible content. Well done!
Dude this video was fantastic!!
Good video! I've seen few permaculture videos so for once I actually had some clue as to what was going on. Keep up the good work, you make some of the best videos on this website!
I'm here! just got the notification. will be watching after my dinner's ready. yay!
You said in your pilot video that everyone can do the research, I googled half-moons and I found exactly what they were, but is not the same when you explain it with details
this was my favorite video so far :p
Haven't watched yet so here's my guess.
The crescent shapes are meant to capture water flowing across the surface and let it sink in promoting water retention for desert reclamation projects.

love this video pls keep working on more
YES! My favourite genre of video
Funny enough my very first thought when I saw the shapes was that they were water conservation rings, there have been great strides made to prevent desertification in sub-Saharan Africa using these trenches.
Good editor
Great video, dude. Cheers!

Man! I love watching your videos and flying over such interesting places in Flight Simulator, pretending like it's an expedition.
the strange things in the desert arc has begon
10:00 - Hah no way! That was exactly what I initially though it would be, since TH-cam pushed a video to me showing the project in African trying to combat the deserts.
when the half moons were brought up, it immediately ticked with me what they were for having watched a video on combatitng desertification in places like the Sahel and western India
First time I predicted the answer before clicking on the video!
I immediately thought of swales and Andrew Milison.
My God, I LOVE your videos!!!!!! 😻
The eighth wonder of civilization!
As an Iranian, I feel that the Iranian government does not care about this part of the country and for some reason does not want to develop this region.
Pashkun gets on an average 23.24mm of annual rain. I guess they try to save whatever rain they do get into the aquifers.
I wonder if Andrew Millison knows any more about this. He is an expert on permacultures and works on landscape scale restorative projects all around the world including India and the Green Wall project that is being worked on by North African nations in the Sahel. There they do a lot of those smaller half moons. But he might also know more about the contouring project in Iran?
These are called crescent catchments
Alright, I enjoyed it! :)
It was almost immediately obvious to me that these were some kind of groundwater control system. I may be watching Andrew Millison too much. But yep, why else would you do something so extensive and seemingly following contours of the earth. However, they were too big. I am used to the small ones.

I built those things volunteering in Botswana.
Pskov is a city in Russia, a relatively large one at that, and nothing to do with this Iranian village. Google Translate might have decided to translate the Farsi word containing a similar string of sounds to that mistakenly because it recognises that city name but not this small village.
BRO SPEAKS FRENCH TOO
Yes, they also use half moons in the green belt on the sahel...
it's cool and all, but I do wonder if there'd be a spot in the map that'd top off the Vox Madagascar one you did.
Man i searched semi circular buns and got something completely different
I made a screen of these and showed to chat gpt and asked him about it. It answered me in few seconds and told everything that is in this video. Im not saying that you are useless. Your videos are very entertaining ❤
I like this guy & Johnny Harris. LOL at the Hindi song.
Aquifer*… obviously related to flood, agriculture, etc.
Can I get the name of the camera you use.
Iran mentioned lets gooooo
I loved this, thank you!!! Wondering why we don't try this in our western desert/arid areas...oh, that's right, people in our country think government is a waste of their $.

Here we go again
Totally forgot you could speak french, ain't gonna lie aha. Great video thanks a lot!
12:42 you use jhony haris music here do you have a licenece

If they were efficient, there should be some vegetation growing, or some darker area where the water is being held back, I guess.
Maybe they used to be greener when the climate was different.
This was great and makes me wonder about the agricultural hub in the southern US, around the Colorado river. Massive area of crops in the desert. Most of this is in California, and last I heard, they did not agree to ration water usage from the river. Climate change + water rights talks? I’ll start digging some contour bunds 😢
Why 3:30 Bollywood song is playing in Iran? 🤔
By the way, song name is *Ankhon Mein Basa Lunga*
because bollywood make most of their song in a iranian language called urdu
Ahh Christophe tu es francais?
It's definitely completely unrelated but... Those patterns look so similar to the lens effect i saw during the Total Solar Eclipse in Oregon. It covered stuff with so many crescent moon shaped shadow patterns
Man you should look up the old us Nike bases along California and the history behind these cause they are all over
Here.❤
Those who watch Andrew Millison knew instantly
Solid
I noticed you've been spending quite a bit of time on Google Earth, focused on the Middle East. What specifically are you hoping to find?🤔🤔🤔
While prod. quality is high, but content wise?
Seriously no geo. ppl knew what these are? CMON man
same is happening at search party: nice images but meh stories
Tunnel Vision ha!
15 min is way to long for an expectable conclusion, but maybe I am just not the audience.
1:40 It's not Pskov. It's Paskooh. Google Translate is not good at Persian language.
kinda like lots and lots of microdams
Shai-Hulud 😅
Fish
Great but hope next time its something different not again exploring how some fights drought, some of your viewers should look less at desert maps
I'm not sure you know what the channel is all about
I don't think it's about deserts...
I found this very interesting, informative and well done, enough for me to subscribe.
I also believe in the Bible and God has other plans for this world and even with all of mankinds efforts man will not be saving this planet, maybe you should research that.

As someone who lives in Iran this video made me so happy! thank you 🥹✨ if you need any other help regarding your future research let me know i would love to help ✨
for the algorithm
Me :)
I recently watched this video. So timely!
th-cam.com/video/xbBdIG--b58/w-d-xo.htmlsi=dv1tovlue6qpFAoS
ayyy
3:30 is that Mohit Chauhan
Ankhon Mein Basa Lunga song
you don't need to hold your mic like that
sweeet
...have you tried asking ChatGPT??? It explains it all just from the satelite image...
@christophe th-cam.com/video/WCli0gyNwL0/w-d-xo.htmlfeature=shared more details if interested
Yep, was also thinking about this video on the Great Green Wall Initiative in Africa.
I guessed what these were from watching @dustupstexas
