Floating cities as an innovative response to climate change | DW Documentary
HTML-код
- Опубликовано: 5 июн 2023
- Sea levels are rising due to climate change. Many coastal cities are at growing risk of flooding. Architects are trying to react to this development with new ideas, such as floating cities. But this concept is not without its problems.
Architect Koen Olthuis is constructing a floating city in the Maldives, sustainably cooled with sea water. In the Netherlands, Sacha and Jan live in a waterborne section of the Steigereiland neighborhood. It's based on a complicated feat of engineering - but also depends on cooperation and solidarity. If one home is too heavy, it raises the one next door. Yet Sacha and Jan like its collaborative nature. The residents of the floating neighborhood all love living by the water, not far from the heart of Amsterdam.
In Germany, a University of Kiel project goes even further. Biologist Martina Mühl is researching the possibility of implementing aquaculture very close to home, so residents can tap their own fresh local supply of fish and seafood.
Hamburg and Bremen have been responding to rising tides by constructing ever higher levees. But soon even this will no longer be enough to cope with the growing impact of climate change. This documentary shows possible alternatives to levees and how we might be able to cope with the rising sea levels in the future.

As a dude who sails and has spent time on the water, I can’t imagine a community that could weather storms and high wave situations long term. There’s a reason why they aren’t common and with sea level rise and temp rises we get bigger and more severe storms.
You may try to stay over a deck barge long 400 feet, quite different from a sailing boat..
Did you actually see the sea-level raised? Or just the storm surcharges? I lived at 20ft above sea-level and hasn't seen any level changed in decades.
@@wayneyd2you probably live in another planet. I live in an island and we all here have witness it.
if allah can give 14 kids, ask him to low down sea level. After all he is almighty 😂
Precisely. A bit on the vulnerable side. In my point of view as someone who has been looking into this for decades following the data seeing the Dutch planners operating with a premise of a 2100 horizon is just laughable. This already is an emergency. Most of us just don't choose to see it as such yet.
I’m also worried about people dumping trash, detergents, and all kinds of stuff into the water. They could try making it illegal all they want but where people gather there’s inevitably going to be waste, especially hazardous waste.
my thoughts as well
Every piece of plastic who lands on the ground on land will eventually end up in the sea.
@@charonstyxferryman
Right. There aren’t ever any urban projects that could end up exacerbating the issue.
90% of plastic are from 10% of the world's rivers. The best way to mitigate the effect is to support things like The Ocean Cleanup project. Problem is not people throwing things into the ocean as much as plastic floating into rivers during heavy rainfall. Unlike the problem of global warming this is something that can be solved and addressed very easily with relative low cost.
True ty! Dana Durnford at Nuclear For Dummies underscores Fukushima has 4 fully blown out spent fuel pools and china syndromes and just had another massive quake resulting in another meltdown and the entire Pacific is already caput.
Not a far-fetched idea, but need I remind everyone.....the sea doesn't always stay calm. What will happen to the homes and cities when you get rough seas and tall waves from a tsunami, or seas like those in the Atlantic, or the Baltics. Those waves are not going to be gentle with whatever you build on them. Whatever you do, the homes/cities must stay level in whatever weather conditions, cos if you allow for them to go rocking up and down, imagine the contents of the homes when they start rocking. It's no different from being in an earthquake. Anchor it to the seabed? Then how is that different from building on existing land? Moreover, if you have to build anchoring foundations into the seabed, you're already disturbing the ecosystem and marine environment underwater beneath your floating city. That would be worse than developing existing land.
Not to mention the problem of plumbing and sewage, and the sea air's corrosive effects on electronics, electrical items and everything else made of metal. Plus the cost of delivering electricity from the power stations to homes and buildings. You can't go underground or undersea as all that cabling will become like a net, trapping and killing marine life underneath your cities/homes. Overhead cabling? What happens when heavy storms come and your floating cities/homes start rocking and pulling on the overhead cables? All you need is for one cable to snap, fall towards the sea and touch the water. Anyone in contact with the water is electrocuted immediately. Each home/building gets their own generator? Then your floating city is going to be even bigger and taller than land-bound cities of equivalent population. How is that good for the environment?
It's a very eye-catching, very sensational, very unconventional idea. But when one digs deeper into the engineering challenges it poses and the costs, both financial as well as non-financial, one might be better off just building sea walls on the edge of every coastline. Trust architects and designers to come up with unconventional or pretty solutions/ideas, but always always consult the engineer on what it will cost to build, and to subsequently maintain it. Architects/designers want to build beautiful things. Engineers want to build things that work, are safe, and will last a lifetime. I trust an engineer more than I trust an architect/designer.
You could use solar and wind to power each home? Most earthships etc are off grid and do it like that. You don't need to power much really.... the corrosiveness of the seawater though, that'd be an issue eventually....
@@AnaFromTheShire I do think that the technology is there to make it possible, but definetly not at a large scale.
So... a far fetched idea, then!
it's sad that the documentary didn't mention how floating houses would overshadow seaweed that needs light to produce oxygen for the marine ecosystems
Also what about human waste
Long term consequences of marine life and what kinds of materials and also what happens if there were to be a tsunami?
seaweed farmers can help.
@@mandingowarrior6846 mussels
@@i00lo60i think he doesnt just mean defecation but waste as in plastics food furniture etc, people already dump those in the forest ocean. This would just make It worse
I've been hearing the sea level rising crap since I arrived in FL in 1993... but the only thing rising are the house prices by the coast.
lol for REAL. I mean WHERE, where is it rising? not at the statue of liberty! Not in Hawaii! Not Plymouth rock!
Popular Science magazine suggested this for New Orleans more than a decade ago.
One problem I noticed with floating homes is Ambulance access. Docks need more room for emergency services.
You are right. But we have same problem on the land too. I mean many cities have narrow streets and they make impossible to get into for ambulances or firefighters.
I remember reading that article
A decade.
They were building floating homes around Seattle and environs some forty years ago.
Simply Google and all will be revealed.
I believe "This Old House" did a feature on this too. Might have been Bob Vila as presenter or perhaps Robin someone???
That's the biggest issue you see? No wonder the planet is dying. Pathetic.
Floating house is basically concept developed in reality by Vietnam. Mekong Delta is live proof where floating Market is rocking destination for the tourist.
However appreciate DW for their initiative to highlight such futuristic issue and to guide how to tackle.
People been making house out of bamboo or drift wood on river for hundreds of years around asia before Vietnam even exist.
The rocking of the floating homes seems like a headache :/
It's an interesting concept but wind smashing against the structures and the rocking seem like pretty big problems
I've lived on a shipe for a while and you do get used to the motion pretty quick. Feels weird to come back on land where nothing moves under you lol
It's hard to imagine something like that here on the West Coast of The South Island of New Zealand, where there are often gales, and there are usually large swells and waves pounding the shore.
I know aye. I’m having a hard time imagining them surviving on and around the Wellington Harbour
It's hard to imagine documentary makers more ignorant, credulous, and gullible then these ones.
I was bouncing around the idea of floating homes very similar to what you see here, nice to see that other people have been thinking about this stuff.
These floating homes and establishments are all and good until you are hit by category 4 or 5 typhoons. The storm surge alone will erase them in hours. Take it from a Filipino who have experienced The Super Typhoon Yolanda (Haiyan). - respects from 🇵🇭
I think instead of $265K for a house on the ocean it's better $67K in a camper boat. House on the sea, can't go anywhere, but our boat goes outside the region/country. Plus, road maintenance costs are a shared expense, and house maintenance comes from personal funds. Meanwhile, for camper boats, the maintenance costs are personal costs.
Cooling homes with deep seawater is really cool. I'd never considered it before.
Cause it does a lot of damage to the structures when you use it. The sea water eats away at the materials so you usually need extremely extensive and expensive maintenance. And even then it can cut the life expectancy of the material by massive magnitudes.
Though it looks good from outside, but there are still a lot of challenges & obstacles to cover on ! ☝️
Amazing Documentary DW❤❤❤. Your Documentary is so Motivational❤❤❤
Initial costs are cheaper, but longer term maintenance will more than eat that up (that's a common theme in "cost savings" for lower income people). There will be more drownings of children and adults. It will change wave and currents causing erosion or deposition patterns. There will be more pollution of water, if not lazy people tossing in trash, then spills of cleaning chemicals, fertilizers, etc. Maybe it's better if we fix the root causes of sea level rise, over crowded city centers, etc.
I love the idea of living in a floating home. However, since it would be salt water, how would electronics hold up against corrosion? Frequently replacing such things would get quite expensive.
I don't think that you put your televisions and computers IN the sea water. I have lived by the sea for decades. Salt in the air during storms is a problem for window frames etc. but the electricity connection and telephone connection is overhead, suffers no problem with salt although the telephone was disconnected for a day or so because the telephone pole which serves several houses was made to lean by the wind in one VERY ferocious storm resulting on several cables being stretched and snapped but that was 20 years ago. Electrical/electronic equipment in the house is not affected by the salt in the air at all. Salt on the roads in Winter is a far bigger problem for cars everywhere than wind blown salt by the sea. Solar panels are not so good by the sea as depending upon position they can be quickly encrusted by salt, thereby partially obscuring the sunlight. Cleaning them after every storm is fine for a year or so and then people lose interest .... "I'll do it tomorrow."
Harvesting seaweed (23.40) is a good idea. In addition to being iodine rich,, a very good supplement, there is also your daily dose of PCBs, dioxins and, thanks to the French, you will glow in the dark reducing you risk of being hit by a car at night. There is nothing like French nuclear waste adding to the flavour. Thanks to little tidal movement in the Baltic, Finnish nuclear waste will stay close to the shore. Finnish seaweed could be marketed to the Swedes whose main hobby is committing suicide, "FINNISH SEAWEED ... Killing you quicker than smoking".
Its only possible for a calm and smooth waves, what about during typhoons and hurricanes where there is rough waves, will it survive?
@@parralel2924 you have stay out of hurricanes path. Look at this: "The "doldrums" is a popular nautical term that refers to the belt around the Earth near the equator where sailing ships sometimes get stuck on windless waters." That's the place where hurricanes are generated from, taking strength later
as soon as a tsunami or tornado rolls through....
Yeah that is right.
It is located in a protected lagoon. These things have been taken into acocunt.
You need to watch it before commenting.
dont worry bro its foldable and unbreakable😂
a tsunami will destroy most buildings anyway, floating or not..
thanks for another nice documentary! Would be interesting to get to that floating city in Maldives)
i'll be 39 this year - in my 10th grade AP-English Class, we had a Future Problem Solving event. Groups of AP students nationwide came together to research this topic and prose solutions in a MLA format.
so many years later, it still hasn't evolved past the 'floating cities' phase.
yep stupid idea, it shows the desperation of that company to be relevant on the market
Ah yes, I love me when instead of solving the problem of pollution and CO2 emissions (which is mainly done by oil companies, planes, concrete and cars) we should build floating houses because deep down we know that the higher-ups at the top of it all are so arrogant that we are better off changing our whole way of living rather than try to convince them and or make them deal with the consequences
cambodia's floating village has been rising and lowering with changes in flood and water level for years, even have floating school and churches
Tell us about the water quality under and around these floating cities. It's the same as a sewage plant mixed with a garbage dump. That's all fine and good right? Nice toxic soup town. I'll pass.
@@darrenwebb5334 no I was telling it to well-educated people.
I have been watching DW documentaries since covid pandemic struck and everybody was under lockdown. The quality of content related to nature and ecology is top notch. Always waiting for more contents from DW on environment and nature topics. Keep up the good work.
Thank you for watching and your positive feedback! We're happy to hear you enjoy our content :)
Watching dw documentary really helps to get over my depression
I practice my english with these videos, thank you so much and the videos are really goods
Come to Lake Titicaca and see how it can be done! 😊
For me it was eye-opening and quite interesting and informative. I think DW did great work on issuing such important questions. But they didnt mention all the negative consequences of building these floating houses. Like everything in life, there are trade-offs. Building homes and cities in water may solve some problems, but at what price? Does it worth to pay the price? These questions were not answered at the documentary. However, great job DW! :)
Thanks for watching and sharing your feedback :)
That is because DW is garbage. A lot of their documentaries are one-sided and biased.
And where is the freshwater coming from? If we're going to have thousands of desalination units well we might as well bring everybody to Australia and put them here where we have land and then they can have water. Land is not the issue
That all sounds like a lovely introduction to the "Ocean border wars"
Since Oceans are mostly bordered wildly, You can see where humanity will go with claiming that "land"
The balancing issue they mentioned in Netherlands seems like it can be solved via a combination of software and hardware. The software could detect the tilted then use hardware to compensate within seconds or minutes. I'm thinking of a ballast system.
Thank you for these team members to introduce new ideas and deep problems running in the world through a very good understanding method to society.I really eager to see the making of floating cities in the modern world,but at the same time it is very fearful about aquatic ecosystem.The materials using for the floating houses must be ecofriendly to environment and marine world organisms.
That literally the first thing I thought about.
You do know the problem is not the land it's the water ? In Australia we have 25 million people for a country the size of the United states but because we don't have any water we can't bring people here
Wow what an amazing video!! Never heard of this concept before, thank you DW ☺️
Thanks for watching :)
DWs Climate change and global warming scare tactics are just getting out of hand, its every day now. Open your eyes please sheep.
This is amazing. Neighbors know the significance of communicating with each other.
Thanks for watching!
Kachovka dam is broken, Kherson is under water. you advice for floating city came on time. Bravo.
Waterworld the movie part 2
I’m so sad about the reefs. The idea of the beautiful, colorful and abundant Coral going extinct absolutely breaks my heart.
not true, great barrier reef saw record growth this year. look it up
@@johnholland2825 I actually read an article about this sometime during the beginning of the year where they articulated how the coral reefs are still in danger. Also the Great Barrier Reef isn’t the only reef in the world. We don’t know if they all can recover it even if the GB reef will make a steady recovery or not. Not to mention variety is as important an all of the growth in monoculture. It’s pretty much entirely a genus called Acropora. It’s like filling a redwood forest with pine trees. But it did grow so you are correct about that.
@@johnholland2825 The Great Barrier Reef grew back a bit....after many years of decline.... yay!? Coral bleaching, increase in sea water acidity, crown of thorns starfish - then if the sea level rises quickly it will take decades for the coral to catch up - as water depth is critical for growth and health of most coral types. And then there are increasing instances of cyclones, and severity of cyclones which can damage reef systems.
As a (sailboat) sailor, I has one simple question: Would those water-cities survive a cyclone/hurricane?
My problem is flat the walls, which are an excellent sail. A hemisphere or something like that, would be better IMHO.
A few heavy structures can survive a serious cyclone. The floating cities may stay in the equatorial area of doldrum where the cyclone are originate from, but with low winds.
We're now at the point of having to find alternatives to living on solid ground - because we can't count on it being there, anymore. Wow. 😳
utter nonsense - sea levels are not rising. What is Plymouth rock? What is the Statue of Liberty?
@@johnholland2825 Stupidity is a sin and climate change is the punishment, you will see
And there's quite a bit of the world's population that either doesn't believe in climate change or are doing absolutely nothing to fix it.
Like the idea of underwater rock formations and plants around the houses that float on the sea. These things may be able to limit water movement and forces on the houses.
Do you mean just like mangroves, because they do just that.
Stagnant water should be avoided. Pollution, and a good hunting ground for 🐊.
Quote,
These things may be able to limit water movement and forces on the houses
Aside from the rising sea level, some islands will eventually disappear due to tectonic activities. Some may abrubtly submerge due to slipping where one side is going up or go down and may move at least 1 meter when energy is released. Some islands also have receding shorelines.
Inflation will make you move faster than tectonic plaques
I saw a TV series about wealth ppl building dream homes about ten years ago where a man made a home on stilts that could slide out of a shaft like pistons and buoy the house like 20 feet if the water rose on the canal where he constructed it. It was a cool idea, and allows for the home to be stationary if the water level rises, rather than just be carried away in a storm.
I think that series was Grand Designs here in the UK. It was an absolute nightmare to build that home and it cost fortune.
This is coping with climate change, not combating it. Definitely something we should be investigating, but as the PM said, curbing the need for this in the first place should be humankind's #1 priority.
This video about floating cities as an innovative response to climate change is truly fascinating! It's inspiring to see the creative solutions being explored to combat the challenges of rising sea levels and climate-related issues. Floating cities offer a unique approach that not only addresses the need for sustainable living but also embraces the beauty and adaptability of our oceans. The future holds so much potential, and I'm excited to witness the progress and possibilities that these innovative ideas can bring. Together, we can create a more resilient and sustainable world. Keep up the great work in raising awareness and sparking important discussions.
Actually this is an idiotic response to climate change. Rather than address the actual cause, this proposal is to avoid some, key word here some, of its effects. Climate change has hundreds of problems outside of flooding, mass droughts, drying up of fresh water sources, tornadoes, etc etc, what are "floating cities," going to do when you have no food or clean water?
The sea isn't rising.
The land is sinking.
Isostatic rebound.
The entire Atlantic seaboard is subsiding, or sinking.
USGS released a report earlier this year.
NASA satellites confirm this fact.
Sweden is rebounding.
(isostatic rebound)
Most of the coast of Alaska is being heavily weathered away.
Just a 24-hour video can demonstrate this fact very obviously.
I think that the sea level rise conspiracy theory can be easily connected to millions of different waterfront property real estate scams.
If Barack Obama did indeed believe that the sea level was rising, then why did he spend $17 million dollars on a piece of waterfront property in the most expensive neighborhood on Earth?
Even this youtube channel smells of con scheme.
@@alb0zfinest I trust in God, not fallible people, but great argument regardless, going into conversation with the w0ke is like slamming your face into a brick wall and expect it to fix your tinnitus..
@@alb0zfinest And also flooding houses have downside too, such as because of their pipe waste coral reefs are dying.

I love floating houses. I'll definitely get myself one when I grow up.
house boat will be more make sense, how you will survive if there are super storm coming your way? with house boat you can move it to another area before it hit
We have some small floating urban neighbourhoods in my region of Canada. People also search out a likely inlet to just set up an individual dwelling.
Must thank DW for this excellent journalism. I thought I was the only one learning of this concept through this documentary.
Thanks for watching!

I haven't yet watched the full program but off the top of my head I worry that this type of floating community will introduce even MORE pollution into the oceans from leaks from utilities, sewage etc Say I do some cleaning/washing - where does the dirty water end up?
The water under and around any floating city will be a toxic soup the same as mixing a garbage dump with raw sewage.
THIS is an exciting project. I like the idea of living on water and also implement new and better ways of using existing land.
We have build-up our flood plains, marshes and filled most places with impenetrable concrete. These are few reasons why the floods have so heavy toll these days.
But in the 1-2 sea level rise future (likely by 2100), adding just these is not enough.
I'd say: DO NOT BUILD UNDER 3 METERS FROM SEA LEVEL. Unless structure floats, is designed to be under 3 meters of water (specially during storms), is build to sink under waves or can be easily relocated.
where have the levels gone up tho? like what coast city has seen a rise and at what amount?
Good question. I have friends that live right beside the ocean and according to them it hasn't moved.
i live in tampa bay and the bay water lvl is the same as it was in 1920. i have a family picture of the bay from our bay shore boulevard home @@darrenwebb5334
Indeed, I learn exponentially about the technologies, strategies and new ideas being developed to combat climate change in different parts of the world. Amazing and bright minds at work that will make an impactful change in each nations approach to this ongoing issue. Thank you!
Thanks for this documentary....
Thanks for watching!
Amazing documentary regarding solutions to climate change.Keep it up 👍.
Thanks for watching and taking the time to comment.
I believe the root of the problem should be addressed firstly. This is addressing the symptom.
Great documentary. I was waiting to hear updates from the floating city in Maldives. This is a huge step forward for Seasteading. This technology isn't just a great a solution for climate change. It will also liberate us from each other and allow us to create communities of like-minded people sharing the same values, goals and aspirations without having to constantly make compromises with others at the expense of our basic rights. Having to engage in endless arguments with folks who don't share your values, and at times hate your guts, is one of the worst aspects of modern society.
Thanks for watching and sharing your thoughts :)
The Maldives ARE NOT being flooded by the sea.
They have a live cam that you can watch.
Those islands are ancient volcanoes that are eventually going to be weathered by rain and the Indian ocean.
But not anytime soon.
Could take millions of years.
The south Pacific has thousands of atolls like the Maldives.
Most of these islands were created by mantle plume hotspots like Hawaii.
Basaltic rock is loaded with iron that corrodes very quickly.
Mantle plumes erupt basaltic magma.
It is poor in silica, and heavy with sulfur dioxide and iron.
It turns red and then falls apart.
Now you know the truth.
Floating garbage, harder to maintain, move to the mountains if your so witless about the climate..
for real
@@GuacamoleyNacho I would urge you and The Hans to learn more about Seasteading. You both sound woefully uninformed on the topic.
Thank you DW for your always insightful documentaries.
Thank you for watching!
Most genuine and concerned about climate change...... Thank you DW.
Thanks for watching :)
Great ingenuity
Its awesome to see innovation come out of necessity, which is something we will never attain here in the states. Innovation only comes out of profit potential, which is why we are far behind and will always be behind in terms of innovation.
People live on boat homes now in the states.
The time to slow down, take less, produce less... has been NOW for awhile. Too bad the only thing humans understand is, "too little, too late".
Affordable Housing for the displaced population should be the priority
Thank you DW Documentry For Caring about the Climate Change ❤
I don't mind living in s houseboat or floating houses in a river or Bay, i love the water in any shape or sizes
This is SO resource intensive , first flood the Sahara depression and save the current populations being lost.
How do you propose to flood that?
@@vondahe the current idea is by tunnel from the Mediterranean
I haven't seen a change in the coastline in my country in 30 years, is the sea levels rises only happening in some places and not others?
@@weird-guy Coastal erosion is normal from large storm tides from time to time, but is the coastline actually receding? I have not seen any of the cities around the world experience any flooding...most of them are located on the coast...Just curious as I have not seen a change in my area in 30 years, it is identical today as it was in the 1990s...
I love the bright colour concepts.
Cars and overall city appearances have become so dull unless it’s LCD powered.
But I get bright paint is more expensive.
Building floating cities is two expensive, just build new developments, at higher elevations. You also have to consider tsunami’s and tornadoes .
If this ever happens, the ocean would be a wasteland 😂
Very good documentary with fascinating content.
Thanks for watching, we are happy to hear you enjoyed our content :)
Human beings population is a huge factor to the problem. In my lifetime alone I've witnessed us passing the 6, passing the 7 and as of late around November 2022, we now have also passed the 8 billion mark. One child policy on a world wide scale should be on the table as an option.
Asia and Africa both have floating cities... they've turned into cesspools of garbage and raw sewage... what could go wrong?
I guess Asia and Africa means the whole world, got it.
All these are nonsense
It's sad that we've gotten to this point when we known about the problem for over 50 years now.
More attention should be paid to other solutions such as dredging the oceans presumably on the continental shelf. Also it should help to raise as many wrecks as we can from the seabed. Houses that float simply simply raise the sea level and so do floating islands. We must use solar evaporation plants to obtain water from the sea. We should collect rainwater at sea.
Glad to see this 1960’s idea being revived; never too late.
This is amazing. Great invention.
Great documentary, thank you
Thanks for watching :)
the contamination of the sea will be another problem with this type of house bulidings
The water quality will be a toxic soup the same as mixing a garbage dump with a sewage plant.
Why not make a adaptable connection between houses? In mild weather the base is rigid and there is no movement, but in the storms you open the flexible joints to move and you gain more survivability. You may also use extra pontoons on the edges to give some additional help. And you may add flexibility to the side that needs it at that time.
Active adaptation.
Could floating barriers defend the floating city or structure?
Wholeheartedly agree with the climate minister. This is like sticking our head in the sand. This documentary boils down rising oceans to "we will have no place to live" and completely neglects equally or even more important topics such as: The huge potential economic loss due to losing infrastructure and housing to the ocean (seriously, we struggle to house the world as it is, how are we gonna afford to move billions of people onto the ocean?), loss of agricultural land, loss of sensitive and important coastal and river biospheres, loss of food sources in oceans and rivers, loss of significant cultural sites.
If we tip the arctic sea ice, the antarctic ice shelves, and the permafrost in Siberia (and this year's charts show that we just have), then we're facing METERS of sea level rise.
An informative documentary. What a brilliant research and articulation 🎉
You have been brainwashed by MNC's.
What about moving to a higher land?!
To prevent the need for building dams to protect the mainland, floating houses were devised. However, to shield these floating houses from the effects of wave motion, artificial reefs were constructed around them. Floating houses are more expensive to build than those on land. I'm not even addressing the transportation issues and the cost of maintaining communication of floating cities right now. Both protecting the mainland with dams and safeguarding floating cities with artificial reefs require the same thing - moving large volumes of ground. So, what's the benefit?
Certainly, in places where there is insufficient land for habitation, this could be a solution. But...
It's called a storm. Storms have always been. Always will be.
And water levels doing the late cretaceous period was 200 meters or 656 feet higher than it is today, the climate has and will always be changing.
The idea of floating cities has been long explored by the poor in Lagos, Nigeria, out of necessity. The people of Makoko have no other choice than to live in slums floating on the Atlantic Ocean in Lagos. Although not sustainable nor ideal, this could offer practical insight to anyone interested in the concept.
Communities that lives in floating cities should start farming their own food from the seaweed and kelp basis. Farming those in the sea may take large amounts of carbon from the atmosphere and give food and some profits to the farmers. If you farm other species like oysters in the mids, you gain even wider mix and more profit chances.
You should also allow fishes and other species live among those farms. When doing so, you may get an diverse ecosystem. Choosing local species to grow is wise, because bringing foreign species may endanger the local ecosystems and even the farming rig itself.
Southeast Asia has been doing this immemorial; even if storms cause damage, they use natural materials and simply rebuild.
Thank you DW for another informative documentary!! I start my days with your videos.
Thanks for watching:)
Big storms are going to be very rough for anyone living on those structures.
Great docu. Surprise nobody mentioned Venice, Italy. Isn't this like the original prototype for this idea?
Venice is sinking.
@@collectorguy3919 fair point!
In Venice nothing is floating, it's built over hundreds of small islands and that's the reason of occasional flooding
What about people who get motion sickness?
I must live in a unique part of the world where the sea level doesn't rise... I surf everyday and the high and low tide marks are exactly the same as they were in the 1980s.
Lol exactly
If I'm not mistaken the Uros of Lake Titikcaca have lived in floating villages for a long time?
For people living off the West Coast of Canada - in the vicinity of the Cascadia Subduction Zone - the residents of floating cities would be the first casualties in any large subduction quake caused tsunami.
The floating cities should stay in the high sea, far from the coasts, in the deep sea the tsunami are not even visible, since they travel under water and they raise compressing the water reaching the coast.
Good overview of a world issue DW. Keep them coming. Or as we say hereabouts - hals und beinbruch.
Interesting concept ,however what happens if there’s a storm,etc?
Floating knowledge for floating cities?Good idea
I like this Documentry & this DW channel Great Technology 👌👌👍
Great. This document covers various aspects of floating cities,indeed.
