Disappearing beaches - The trouble with sand | DW Documentary

- Around the world, beaches are under threat. Severe storms and sea levels are rising. Huge quantities of sand are being washed away into the ocean. Even entire islands are in existential danger.
In Germany, the island of Sylt is battling against disappearance. Its beaches, like those of other North Sea islands, have been under assault for decades. Authorities are trying to halt the loss of kilometers of sandy beaches with construction measures and beach nourishment. Big sand dredging ships play an important role in this process. They remove enormous quantities from the seabed and pump it back onto eroding shores.
Replenishing an shorelines in this manner costs several million euros a year. But the financial expense is not the only problem - the ecological price of these significant interventions into the fragile maritime ecosystem is far from clear. Currently, people are still putting coastal protection before environmental protection. But there are debates about whether this strategy can be continued in future. After all, sand is the second most important commodity in our modern society after water. It can be found in concrete, cars, computer chips, cleaning detergents and cellphones. And because desert sand is too fine, all of this sand has to come from the sea or from rivers.
In total, between 40 and 50 billion tons of sand are used each year. As a result, sand has gradually become a scarce resource. Meanwhile, many countries have seen a rise of illegal sand mining organized by criminal gangs. Sand mafias plunder and destroy entire regions. The workers who remove sand from beaches, the sea, or riverbeds often do so under hazardous conditions.
Researchers are working hard to find replacement materials and innovative recycling processes. Sand may seem essentially limitless, but global demand far outstrips availability.

DW always has some of the best documentaries. Sand mining is another one of these ecological nightmares that we will have to face. World has finite resources and we have to find alternatives. Too much of a thing is not good but humans are not understanding that.
Thanks for watching and sharing your thoughts!
I'm a retired sedimentologist and I used to work on these questions. This is a well balanced documentary but I miss two things: 1. A map of the German coastline maybe even a map of the entire Waddensea from Texel to Skallingen, and a short explanation of the currents and tidal regime along this part of the North Sea. 2. the suggestion of building sea walls is often made. These constructions do more damage than good, as has been proven in many other places because they reflect the energy of waves and currents (it can't dissipate) and this retains energy and thus keeps more sediment in suspension and erodes beaches even more. It's not just a question of sea walls being esthetically undesirable
Human is the problem . Nature is doing what it has always been doing.

Exactly, the person narrating says the island would be in trouble because of the loss of sand. It's not the island but the people and money to be made. It would be nice if that was said because most beaches are created or extended with additional sand
@@smithrookie1858 aren't they there to help? 😶
Elite humans are the problem but they want to blame you instead.
@@smithrookie1858 I don't spread fake news thanks and neither should you
"We will have to soon embrace alternatives" - the only alternative is to consume, produce and build less. Every alternative just shifts the problem somewhere else. Our greed and selfishness will be not only the end of us but all life...
Until God intervenes...
Nature finds a way
Unfortunately greed and consumerism without any lack of knowledge, care or more specifically accountability of the consequences,has been happening far too long. Great insight into something that the world needs to know.
Thank you.
Your Documentary’s are Amazing
When all else fails, remember…
Mother Nature ALWAYS WINS !!!
You aren’t going to ‘save’ or ‘restore’ ANYTHING !!! Pbffft !!!
Exactly. Absolute insanity this is.
We germans have to learn to let loose and forget those "holiday paradises" on the northern coasts. they were never ment to last forever and its a natural process of sandy islands to been washed away. other islands grow like la palma shows us very impressive lately
Ja. Das is wahr✅

@@mironRu79 they did. They go now to the netherlands for beaches😂
Just make sure every Arab you keep importing brings a few cubic meters of sand lol
@@mironRu79 Wtf does that have to do with this story or their comment?
I was at Dillon Beach in California this weekend and the pristine beach has been wrecked by storms. There is a 3 foot high wall now where the tide simply took out all the sand. It's all gone now. Half the beach is 3 feet lower now. This beach is historic and it will take months to restore it if the locals decide to. It's really incredible to me that I experienced this issue recently and then got this video notification. It stands to reason I guess...
or maybe stupid humans could let them go out naturally and do not try to change them anymoore? one beach is closed the other is opened
@@anubaral the sand was swept to the bottom of the ocean by a storm. Think harder, if the solution was that simple this documentary wouldn't be necessary.
@@JonnoPlays And it isn´t.
@@JonnoPlays your experience of the beach is very normal. The earth constantly changes. It's called nature. This documentary is necessary, but not for the reason you think. It's necessary to sell a lie, and you've bought it, it seems.
@@JonnoPlays Was it? Where did it go and where did it come from?
Funny enough I watched a doco on sand last week, how its dissapearing due to construction.
How countries are sucking all the sand out of the nearby sea and stock piling it because construction sand is becoming scarce.
The reasons, sand is made in rivers, which are all dammed for green power and sucked dry for irrigation.
Now this doco claims its due to climate change, yet talks about the dredging and movement of sand by humans.
Go to the beach, move sand, watch the ocean remove your work and the sand is still there, yet if you removed the sand manually and put it on land, it cant replenish itself.
When we build roads, houses, etc humans consume large amounts of sand.
Desert sand cant be used for construction.
Sometimes docos have hidden agendas.
Thank you DW Team. Very informative. Very surprised to know few things from documentary such as Dubai imported sand from Australia, beaches are pumped with sands artificially in Germany, beaches void of sands in Africa and so many other things about sand.
Thank you! We're glad you liked the documentary. Subscribe to our channel for the latest uploads! 🙂

Wow I learned so very much from this video. Really had not really ever thought that we could run out of sand. Never new it was used in so many things. Thank you for this program !!
It is a very educative documentary. Bravo DW!
Everything “Man” touches it destroys…
okay, but man is spending billions to put the beach back when the ocean destroys it.
@@davidanalyst671 why not leave the nature in this case?
Man hates his own feeble creation, so everything must be destroyed.
@@davidanalyst671 did you watch the video or just trolling? Dredging that sand up for tourism destroys the underwater ecosystem
@@anubaral they said it in the video. everyone leaves and the houses all end up empty
Thanks DW very informative. I’m from Australia and it really upset me to find out that our sand has been building Dubai. I hate that place. It’s a place built on human slavery. I need to know who in our country profited from this.
Thanks a lot for watching and for your positive feedback. We appreciate you taking the time to comment and are glad you liked the documentary!
Unfortunately some of the facts in this video are incorrect. I am a marine biologist with the university of Miami Marine research institute
The sand erosion is a normal process that’s been happening for millions of years. Sand erosion occurs continually from wave erosion. It’s a non stop effect and costal cities have been pumping sand to replace errored beach sand since the thirties and forties
What we are doing is trying to alter the natural course of costal erosion, not climate change
Letting Nature manage many beaches seems much wiser than us destroying nearby habitats, merely to make us happy for relaxing walks and sunbathing.
facts.
You are right sir
The rich happier…..
@@elinope4745 if they can’t save them, off well. It’s like building in other locations below sea level. IF you can make it work fine…but if you can and you expect the government to save you from nature that’s crazy.
Instead of repeatedly replacing sand, they should replace the sand and spend more off the coast, making a break water barrier. You might even place big boulders or a concrete structure to inhibit the erosion. Spending more once than repeatedly wasting millions is a win, win.
Thank you DW
We just keep finding new ways to destroy the Earth. How can anyone deny we are at fault?
"In nature, nothing is created and nothing is destroyed, but everything is transformed" - Antoine Laurent Delavosier
Maybe we should K*** all the humans 😂
That would actually be great for the other animals. Although maybe our ape friends would eventually become us.
Because it's been happening since before us
"We", I have nothing to do with this greed and want all of Europeans.
Thanks DW, though sad to see what’s happening to our world that was designed beautifully and created to last forever.
And, it will last forever! We have God's promise on that!
Designed?
@@bitTorrenter Of course DESIGNED! Do you doubt that?
Nothing lasts forever.
A Sand sock will make it worse, it will increase the speed of the water passing over (like a wing) and cause even more erosion of the sand around it, ( maybe the study will consider fluid dynamics as a factor ).
Most of the sand comes. Comes from ancient mining from thousands of yrs ago
leave the sand alone, you can't fight or manipulate nature like that and expect to win.
its just a man made beach? well let it go. This is not smart.
You'll never win against Mother Nature
I live in Galveston Texas. I watched them dredge our ship channel to replenish the beaches. Multi-million dollar refurbishing. But, all I could think of was the horrible smell of sewage coming from the air around it. Not to mention, all the petroleum products, heavy metals, and chemicals that laden the ship channel sand. I would guess it was 85% silt and 15% sand. Under no circumstances would I ever let any of my family members or friends play or have festivities on that Beach. It is more like a toxic waste zone then a holiday getaway. Just saying
The sand transfer is done here in Florida also!
The alternative, dredging beaches is a sad alternative. Grew up along Miami Beach., always enjoyed its beautiful golden sandy beaches and crystal clear water on many mornings. Back in the 80's the state decided to dredge or expand the beach by sucking sand from 1/2 mile off shore and pour the sand in the beach. The end result is a gray silt beach that gets churned by the waves into a muddy beach line. It destroyed the beach.
The solution is to built further inland or natural rock berms as breakers.
We moved after almost 20 years of ocean side living.
In reality, little can be done to escape the damage to property when you live on a beach, it the price paid.
Thanks for watching and taking the time to comment.
Were they still disposing of the canal sand out at sea? Seemed like a dumb idea to dump it and then get other sand from farther away...
Thank You for this great documentary. 💖🌊
I'm from Florida, and this is done on our beaches too! Coral that used to exist by the shore has been covered up by sand and killed.
I've been going to the same beach in Deerfield Florida for 50 years. It looks the same.
I live in Florida not far from you and I remember a beach by me completely changed after a hurricane maybe 15 years ago
That’s because those rocks that where put there by man in 1958 help prevent the beaches from eroding as much. Also, Deerfield beach has had major sand restorations in the past.
So it's called "coastal protection" but it destroys the seabed and ecosystems? So it's "holiday chair" protection then?
"Coastal protection" and "beach nourishment".. wow that goes beyond euphemism all the way to delusional.
Shifting sands of time. Sands have shifted from the beginning of time. I see beaches that shrink and I see beaches that grow. I watch jetties installed at an inlet only to enlarge the beach on the north side and shrink the beach on the south side because of the current. Ever since then the govt has spent millions to continually keep dredging to fill in the shrinking beach.
this is not what's actually happening globally.
"In nature, nothing is created and nothing is destroyed, but everything is transformed" - Antoine Laurent Delavosier
Father time?
Wow! Who would have thought and sad that our beaches for some are not longer there. We continue to deplete the natural resources from other parts of the world. Dubai has gotten reacher as many of expensive neighborhoods near a beach because of it and instead of helping the most needy of it who are risking their lives for its survival. The world is full of greed and putting the blame on climate change, when we are the ones who have created this mess.
Thanks for your work as always sir, i really apseciate it.
Good subject dw tv.
There's no hope is there? Human greed will be the end of us all.
Incredibly informative. Thank you! I love your docs - so well thought out
Anakin Skywalker: I don't like sand. It's coarse and rough and irritating… and it gets everywhere ;D
Its better then walking and lying on stones lol
There are very few natural beaches in the U.S. The only places that I know of is in the keys.
Huh? The entire east coast of the US is essentially beaches and all of them are natural.
2 cent opinion.
there would be sandy beaches in the area if the natural environment in that area permitted it.
try to stop killing marine life unnecessarily.
maybe it's not up to us to build beaches where they don't naturally occur, at least not with out some sort of negative impact on the surrounding environment.

What is happening on this small island is the exact same thing happening on the Florida gulf coast. The area is totally dependent on tourism and lots of money is spent on beach restoration.
20.11.2021.Very good documentary.
Likes and thanks for the video.
I saw Playa Bonita...one of the most beautiful beaches in Cozumel Mexico almost eliminated by a near by hurricane. Luckily a later storm brought much of the sand back later that season.
You guys are losing your beaches, but those in the South Pacific are losing their islands, which is where their nations, history, and homes are.
One of the beach front homes is more then 14 mil.
The property taxes pay to preserve there island
So the rough, tough, hard, durable, robust, and hardened surfaces are going to become out of business if this is accurate yeah
Sea is not timeless. I remember I used to live near a beach when I was young. Left the continent and stayed away for 20 years. Went back last year. I cried when I saw what it now looks. Very sad.
We just keep peddling faster, hoping that our civilization's flying machine is in flight, not freefall. But the ground is rushing toward us, and the craft was never sound. - Paraphrase of Daniel Quinn's Ishmael
So truee... never stood still with that fact.. interfering with nature is not smart!!
Offset height and length of station reefs that encourage the wave break and sand and silt dropping out along the length of the beach's shore line's length.
That way there is less frontal impact and overlapping and skimming off the top and into the depths action.
With a space between the reef wave breaks you would have clean and known waves surfing spots, and a set of two lines at different depths and distances from the shore , one tidal under current would impact the other line and encouraged laterally down the the beach line again.
Waves that break over that outer line would be diffused into laterally moving water and be more so diffused of energy ..
If I had a piece of paper I would draw it for you .
There are ways of setting tubes and tidal flow turbines that would also be useful for energy capture comming and going, and also blow back classifying manifold tibes that would blow sand and water back toward the shore line .. lots of designes, sort of similar but opposite a tsunami diffusing system , but yes, it can be done.
Your talking about intermittent breakwaters. Those already exist. Look at Holly Beach, Louisiana. There are 3 miles of breakwaters and the problem is that it doesn’t help because sand moves on and off shore as well as along the shore. When you start interrupting that flow, you create worse conditions downdrift. They still have to pump millions of cubic yards of sand there and they have been deemed more or less a failure. Structures don’t create sand.
Lived in Florida my entire 38 year life and the beaches are exactly the same as they were when I used to go surfing as a child. Still surf quite often and exact same beach. Florida is at sea level. One of the lowest level states in the US and the world.
it's greed people
they want money from tourism
there is no such thing as a "good" company trying to save their beaches...
beaches move, hurricanes, storms, inundations, global warming, etc...
but people arent used to it, they like "stability" and if you invested million on hotels, places, etc... no way in hell you want to "move it all away" when it will costs nowadays 50 times what someone invested 40 years ago...
greed, greed, greed... the human plague that will end us all
The sea is not an enemy.
Human desire is the enemy.
Create zones along the sea where it is not allowed to build.
Limit the insurance over time on installations that are too close to the water.
These zones must be dynamic, to make it clear that one is not protected from erosion.
First you will lose insurance, then the construction
New and informative for me
protecting nature from the disaster caused by nature
The trouble with sand is.. it moves with the currents.. lol
I wonder: could a special kind of plant that could save the coast line?
It's called weed, it'll make everyone not care. The beach is more of a state of mind than it is a place when you think about it
That sand from Cambodia is sent to Singapore.
Authorities are currently pumping sand onto the beach where I live in Ocean City, MD, USA. I call it "umbrella real-estate". It doesn't need done every time they do it (every 4-5 years) and this time it's a year where it doesn't need done. I believe $190 million USD being spent on the project. But the people here hate the idea of offshore wind and have been fighting against major projects for years because they say it's going to ruin the sunrise.... SMH
With the quality of desert sand not working for concrete then no shit?
I was on Mallorca once and got told: most beaches are made by dredging up sand from the sea floor. the last natural beach is near alcudia
Sand plays a critical part in our society and we should protect our environmental resources and find sustainable ways to live with nature, if we keep destroying what world would we live for future generations in these times of climate change
Can this problem be solved by planting mangrove trees? (case in Indonesia, Southeast Asia)
When new trees are planted to replace old ones, how many different varieties of trees are used? Will the new saplings grow into the diversified forests they replaced? 🤔

In the Hamptons on Long Island have been restoring the beaches there for years. Wealthy NYC 'summer tourists' don't pay a cent for the beaches....they are Summer People...they don't pay any taxes at all - it's not like they are *residents* - only the servers, cooks, workers in the hotels do...because they are the ones who live *year round* and are therefore Residents...and so are taxed. This has been going on for years...
They need to plant sea oats like they do on my beach.

The Disappearing intelligence of Man!… you build on Sand?… who is the fool?
Really?!!! How many megatons of sand are consumed by construction all over the world?! Why the rivers cannot run freely to the ocean?!!!
There are a lot of dams worldwide. The sand collects behind it is one issue.
Cheaper to put in rock walls that stabilise the shorelines
is water wet ?
What a scam - some of the worst water clarity on earth and still paying those housing prices?!
The sand was deposited onto beaches many years before humans came by. What has changed so that we have to replenish it?
rising sea level will eat everything, these quick fix wont do anything in a long run, indeed waste of tax
If i understand right in Germany sand pumping is really abouth saveing buissnes (vaccation place for rich people) and not saveing sand beach itself and in process is made tottal destruction of sea bottom and bottom and local life..and you can do pumping onlly few times till all send is destroyed and you can't use it again.

Why don’t they put in break walls?
Where does the sand on thd beach go? You say there is no sand in the places where sand was drenched only silt. So where did the sand on the beach go if not back in the holes? Id have thought the sand will go back to the ocean floor where it was pumped from
It's collected behind the dams worldwide.

All of humanity's problems come back to money. Not enough money for this not enough money for that. The resources exist. Our brilliant minds exist. And yet money, a thing we created and gave value to, it's always at the end of every problem.
We are too many using too much resources too fast on a finite world.
Question is are we smart enough as a species to reduce our numbers willingly
Wrong. Money merely represents, in paper form, the amount of resources that are available to a nation.
This makes no sense. Read the comment above for the right insight.
@@Twobirdsbreakingfree do you know how many countries that’s extremely “resource” rich but have nothing to show for it, least of all is money.

And where does the sand eaten by the sea go??!
