Your country is threatened by the water safe supposed to be is right on top of the water. Its not as float or house its a hybrid. Climate chios is happening its not happening in the future or possibly its already going on. Its the future of humanity. This and the sea levels will continue to rise but by how much. The earth is getting hotter the polar ice caps are melting in greenland and antarctica the ice is receding 6 times faster than expected. Sea levels around the world are rising. Geo mar the Helmholtz Center for research is located in kiel germany some of the worlds top climate experts work here including moji blood teef who studies Global Warming and its effects these are also nice puns these enormous ice caps hold an immense amount of water just imagine if they were to melt away completely good global sea levels would rise by about 60 meters this seems make up. An increase of that magnitude would radically alter the earths geography much of Northern Europe could be submerged the netherlands would vanish underwater but even a small increase would have a major impact major cities in coastal regions and further inland would be flooded. That includes london. Boston. Shanghai. Washington d. C. And mumbai. Yet sneaking out when getting that wont happen for decades or even centuries but if we dont limit Global Warming it will eventually be unstoppable and death even if we stop emitting Greenhouse Gases and hireling it will be its very late the melting of. These huge sheets of ice a Dynamic Systems if they reach a Tipping Point sea levels could rise along very quickly. This is an effect on hype and yet we know that happened at the end of the last ice age. We dont know if it could happen today. And encrease of one meter or even 3 meters is possible by the end of the century or so that i made up this missile. Sea levels are rising and eventually many coastal regions might be. Claimed by the ocean since the 19th Century Global mean sea levels have risen by about 20 centimeters in the South Pacific sea levels are rising 2. 00 to 3. 00 times faster than the global mean the island nation of tuvalu might be the 1st to be swallowed by the way. Fully one half of the netherlands lives just one meter above sea level one quarter is below sea level the country is protected by a system of polders dikes and dams but for how long the netherlands is developing innovative concepts to deal with the projected rise in sea levels. Here in amsterdam a Pilot Project has created an entire community of Floating Homes. Sasha glasses is a Founding Partner of the space and matter architectural studio and he and his family now live in one of the house boats a small building initiatives began acquiring the sites about 10 years ago theres room for about 30 homes. Houseboats here are nothing new but this project is one of a kind. Living on the water is incredible its a dream come true for me this place feels like a Vacation Home you come back from work and you feel relaxed and like youre on vacation remember. Designed the house himself. Theres plenty of living space spread out over 3 levels. You wont find this kind of comfort on a traditional houseboat. Connects the floating settlement to the mainland. Weve got connections to the power grid sewage Water Systems the internet and so on its a plug and play concept its simple and it works really well. As its like when you pull your motorhome into a camping site. You can connect to the entire infrastructure system and others for the one who have to infrastructure. With a living on the water gives you a lot of likes ability. You can expand the community quickly make it smaller you can reconfigure it again and again theres a concept known as a bunch potential. These Floating Homes generate much of their own energy with photo voltaic solar panels. Right now the site is purely residential but sasha believes that this might change one day. Our vision is not limited to house boats you could also have voting schools offices and supermarkets just about any sort of structure actually. A studio Architectural Firm is located in the town of rice mike. The company was founded by kuhn an old house hes known around the world for developing Floating Solutions to problems posed by Climate Change and of an isolation. Of water architects for me that means that you use water to make cities better so worldwide to try to take advantage of the water by building on water by taking the flexibility of the water of death created these that are more efficient and more adaptable. The dutch have been taming the water and fighting the rising and falling tied for centuries. To their lands is an artificial country we are live on the me from the sea level and what we did we built some dikes around it i mean out so now we have a dry country but of course with Climate Change more Sea Level Rise becomes keep everything drained so we now have to see whats the next next step in this surf and testing machine because the netherlands. Body of sea levels continue to rise the netherlands will be among the 1st countries that have to deal with the impact you know we have to take a lot of efforts to keep everything dry and i think whats about architects and other countries can learn from the dutch is that you never can sit still you have to. To think of the next next steps in your inner city and your country and we call this building for change and building for change makes its the you have to be flexible we have to be ready for any change in politics in technology in climate in whatever comes to us and we definitely have to make sure that we can create new cities. Towns in visions what he calls the blue city a floating metropolis that grows out of an existing city by building on the water structures or even districts could be relocated to respond to Climate Change or new social conditions. Is an optimist he believes that architects and durban planners will play an Important Role in helping communities adapt to rising sea levels so we also have to deal with nature and we have to start living with the water and thats a moment that this kind of floating architecture taking use of the water building top of the water is the best because if your city of your country is threatened by the water the safest place to be is already on top of the water. Here in amsterdams i book district people are already living in Floating Homes and apartment buildings its a model Housing Estate that features designs by a number of architects the structures are anchored to the sea floor instead of years there are docks for boats. The neighborhood is also different in another respect its connected to the mainland by jesse and the houses float on the water so how would these structures actually built. Floating foundations that can be from from concrete or from steel of opposites and with that we can make very large floating platforms and on top of that forms we can built almost anything from form parks and green to houses to towers and these are these big platforms we can connect to our cities on the water on lakes or rivers or seas and by that we can take advantage of that space. The range of possibilities seems endless the ocean flower complex in the mall even islands with 185. 00 villas and a floating golf course. The citadel apartment complex in the netherlands a design that would use the water to help cool the buildings consuming 25 Percent Less Energy than conventional structures. A plan for an entire Floating City it features selfcontained Modular Construction and has a lot of recreational space. A design for a floating mosque in the United Arab Emirates and a 25 storey hotel tower in dubai rotating on a Floating Foundation. But kuhn althouse is mainly interested in designing floating residential communities. But only floating villas will never be enough if you really want to cure the problems of space you have to also deal with in high densities and high end densities means that we also have to make floating towers so the next steps for floating cities will be the citys floating mitras towers so we need a tower for rotterdam a Floating Office tower of rice or 8 stories and we do it in seal to cause lemonade the timber and been put on the big fro the foundations you can create almost same density as. One basic idea underlies Water Studios designs and accounts for its International Success people ask me do you want to live on the water yourself while i have a family i have 3 sons and there for me i only want to live on the water if the quality of the call for it is exactly the same as all lent but today with all the technology we have a favorable form the offshore industry and form for this shipping industry we can make that forms that nobody will even noticed that you are on the water. This is the mass lance storm surge barrier in the province of self holland. And they live within the next thing that in the last big flood was in 1953 nearly 2000 people were killed the government said this cant happen again. During the storm 200 kilometers of dikes burst and water levels quickly rose to 3 meters an estimated 100000 people lost their homes after would the government ordered the construction of a system of 15 storm surge barriers dams and other structures. As is need to limit the barriers arent enough there are just a part of the system that helps us to keep our feet dry it sounds simple but its really quite complex. The country is still battling the threat of flooding dikes are being rebuilt and. Planted with vegetation beaches are being widened and sand junes raised. Rotterdam was hit hard by the 953 floods the mass lands barrier is one of the Worlds Largest moving structures and now protects about 1000000 people. The 2 large floating gates are each 240 meters long. The retaining walls a curved to withstand the force of beyond coming water. The barrier is closed only when a big storm is on the way. Rotterdam is europes largest seaport and the barrier is designed to protect it to. Them as against a this is the only barrier of its kind thats run by a computer weve worked hard to eliminate any technical complications that lead to the hours. It takes just 2 hours to close the gates this only happens when the water level hits 3 meters either very very long but they are making a lot about everyone in the netherlands contributes to flood protection through the taxes they pay even those who dont live near water in them more than a 1000000000 euros goes into the Flood Control Program Every year and then. The government also finances efforts to help parts of russia dam city center collect and drain excess water in an emergency. Theres lots of open space in parking garages theyre designed so that they can take on runoff water during floods. Rotterdam is particularly vulnerable to storm surges because of its coastal location and because it sits in the delta created by the rhine and mass rivers. He is an unusual design floating pavilions theyre covered with especially for oil thats 100. 00 times lighter than glass and theyre environmentally friendly cooled by surface water and heated with solar energy. The pavilions are now home to a floating cinema. Nearby a floating park hexagonal islands made of recycled plastic theyve been planted with vegetation and already seem to be drawing a crowd. For a unique city getaway you can rent this small houseboat called a vehicle boat its wrapped in 24. 00 layers of corrugated cardboard which makes it light and just about soundproof. Interior features a kitchen bathroom living room and terrace. This vehicle boat is located near the Rotterdam City Center easy access to sightseeing and restaurants. Despite all the comforts there are constant reminders that you are living on the water. We now return to amsterdam and the iceberg district with its 75 unit Housing Estate well that is from both its not a boat or a house its a hybrid before. We have the units built at a shipyard on the ice america a big lake east of amsterdam on the dow doing better here and invented that Way Construction work wouldnt be interrupted by bad weather even in winter shipyard and in his or her meds that summer when the units were finished they were shipped through the logs to us here doors afrikaans and they are. Those out of there and encouraged to steel poles that were driven 16 leaders into the lake bed. And we designed the connections so that they could bridge the difference in height both of which fill a can of a hole as hope that difference is caused by the tides but its not very big like 60 centimeters just a centimeter and the unit still millions of affleck that includes the jetties which cover the utility lines for gas water heating and so on. You put the lines in flexible tombs which are connected to the units and they can handle the rise and fall of the tide cylinders of dots out open near and over the top he has to have a Different Levels were also designed to adapt to the tides in our home long day. The units actually sit on a Floating Foundation thats composed of air tight concrete tubs. Cause we chose concrete because its heavy and displaces water based on archimedes principle are depending on its waived concrete can displace many cubic metres of water and. Its to her and the head with made concrete dumps in different sizes to balance the weight therefore built above the camera in hills far for example a bathroom is heavy so we made the concrete base and thinker on the opposite side to offset the increased weight loss and fairer we explain all this to the residence. So if someone has a heavy sofa and a piano on one side of the unit they can alter the balance by installing air filled tanks underneath the structure. Look better lock lopes about in the house. Or what else can the netherlands teach us about finding new ways to build on and with water. Again doubt you have to have the courage to try something new people in other countries could use our projects as an example you also have to be willing to experiment and up to. The netherlands also drew on an example the famous Houseboat Community in the city of sausalito california which dates back to the 950. 00 s. Like many communities built on water its legal status remained vague for years. And last but only last how many but we also have difficulties getting a mortgage and house as of danks couldnt decide whether they were dealing with a boat or a house so we had to come up with new solutions. And. In july 2019 paris recorded an all time High Temperature 42 degrees celcius. City residents are learning to live with climate extremes from high heat to heavy rain and flooding. Paris hosted the un Climate Change conference in 2015 where delegates set a goal to limit the global temperature increase to well below 2 degrees celsius in this century. Renowned architect and oceanographer Jacques Rouge has lived on this houseboat in the heart of paris for more than 4 decades. Its located near the plus della concorde and also includes his design studio. And. Yet theyre gone that the 2 Great Adventures of mankind are space and the center 11th this is the future of humanity and the. Rouge area has been working on this futuristic project for decades an ocean based Research Vessel called the sea orbiter its shaped like a seahorse. The project still only exists as a model but its plans call for a total height of 58 meters with 31 meters below the waters surface up to 22. 00 scientists could work in the vessel rouge a recess that we know less about the scene than we do about space yet they knew this for there are millions of creatures to study for example the diversity of cell a plankton is a measurable than mine we only know a fraction of it and there any baccy. The scientists rouge or recalls that aqua norse would leave in pressurized chambers so that they could take part in diving expeditions that any time. Where she big booster lemaire ive lived underwater to the x. Ray ive been involved in a dozen projects on his habitat its to bilk argument ive set World Records for a living underwater down through them and its been extraordinary job in their own davies for the. Swiss oceanographers Jacques Piqua was an early supporter of the project. It. Worked in the deepest parts of the year at 11000 meters. I can always encouraged me in my research on underwater settlements and so he and i decided to develop a research lab that would be like the International Space station. It could drift with the ocean currents. And provide a base for scientists like a beehive and to pick up the worker bees would fly out and collect Scientific Data on the Marine Environment. Since he was inspired by the work of 2 of his countryman van and jacques eve cousteau. In 1962 cousteau spent a week in his underwater Research Facility conch shells. He hoped it would be the dawn of a new age of marine exploration. In the 1970 s. Rouge a really big fan to imagine these future of laboratories and entire villages on the ocean floor. If Climate Change continues to progress the idea of underwater settlements could become popular and again. Designed this huge floating Research Center shaped like a manta ray it would be 900 meters long and 500 meters wide and could accommodate up to 7000 people. A row of design imagines underwater rooms designed for holidaymakers. Value about it over a one day well have Space Tourism and also underwater tourism with facility x. Like hotels and Research Centers had the you know a new reality is taking shape or because it has to. The other architects are getting on board the u. S. Firm solace for came up with this idea for a Marine Research station to be based off the coast of bali. Italian architect john lucas sun tosswill so developed this concept for a modular floating structure called high pick a the individual units resemble vertebrae in the human spine its like a cross between a cruise ship and a hotel. The german Architecture Firm davis buddha ville has designed a hotel that is to be built of the chinese island of high none of the individual suites would lie below the surface of the sea. Mago cross a year a vigil came up with. Plans for a Lighthouse Hotel that harnesses wave energy to generate electricity. Some designs have actually been built the joules Undersea Lodge in florida which opened in 1906 bills itself as the worlds 1st underwater hotel. Leases the atlantis luxury hotel resort located on the coast of dubai it has more than 1500. 00 rooms spread out over 23. 00 floors and an aquarium that contains more than 65000. 00 marine animals. The eat a undersea restaurant in the mall deve islands is located 5 meters below sea level. Europe now has its 1st fully submerged restaurant its called the unda located on the Southern Coast of norway. It was designed by the oslo based Architecture Firm snow hetta. The same firm also developed the concept for this 100. 00 room hotel that lies at the foot of a glacier in the norwegian arctic the hotel will run mostly on energy generated by solar panels. Most of the plans are still dreams for the future designed by visionaries like Jacques Ruggieri is yeah im a dreamer but im also extremely pragmatic met i make my dream is reality of course get out dreamers and to do that you have to be able to think clearly. Just to see our society has caused a lot of destruction over the last 100 years and we continue to destroy. Dettori but we cant let these catastrophes continue. We have to find solutions and implement them step by step over your self than he did. Another vision for living in a Marine Environment the ocean spiral he has 2 Main Elements a sphere and tallis structure that would provide living and work space for up to 5000 people and a spiral structure that connects the sphere to a base station on the ocean floor. Russian architect alexander remys old has designed a modern day no izaak that could accommodate up to 10000 people. Piece of water scraper concept comes from malaysia a floating building that would generate its own food and electricity and house thousands but are ideas like this truly a utopia as we note these would be stopgap measures i dont think people want to live underwater and that humans are used to living on land of course its technically possible to live underwater but i think our quality of life would really suffer with quality of. The worlds less affluent regions will be hit hard by the effects of Climate Change. Is going to impact a lot. So if they say mumbai is one of them took out of those one of them for soccer to ban is going to have a flag so as for the United Nations its on a high high alert actually the whole issue isnt a big threat to the ceiling but in sea level. Some coastal areas in asia are already taking steps to deal with rising sea levels are the has to move his center in an issue no they have to move the whole city center to somewhere else 40 kilometers of it which is they already working on by 20 i think 40 or something other they have to move their city to some other place they already have a plant which are ongoing i think it could be a similar situation for mumbai build some 28000000 people live in the Mumbai Metropolitan Region the core of the city is built on several islands that lie in the arabian sea this is a low lying area and rising sea levels pose a very real threat. Austrian architect ramez najah says that coastal cities like mumbai must adapt to these conditions and that could include building floating communities. Other 2 completely different but sort this im convinced that entire cities will one day be built on water. You cant rely on putting up barriers made of sand or other materials a little bit of. Cities will have to be built on floating surfaces should even a little bit flaking this new development would offer a number of advantages particularly the construction of infrastructure near the city center and projects that generate energy so its no different in italy. Proposes the use of floating turbines that generate electricity by taking in water the concept is similar to that used with hydroelectric dams in the austrian alps you take a look east and the Technology Comes from austria because we have a lot of experience with hydroelectric plants. And the other element is the creative side where architects can play a role. And his brother whos also an architect have been designing water based communities for years and theyre convinced that these projects will become reality. In this play its realistic because its going to be a step by step process i dont think well be seeing mega projects in coastal cities the projects will grow slowly and gradually. We see levels rising even more quickly solutions are urgently needed millions could be displaced by Climate Change. With a big yes. Do you know how many climate refugees there will be. More than 200000000. 202300 1000000 pliant refugees. Where will they go. These refugees will come from developing countries not wealthy countries. 300000000 people where will they live will bangladesh or india take the men absolutely not. It isnt lennon and into things. In low lying coastal countries like bangladesh they cant do much to stop the rising water. They cant build dikes or other flood protection structures like we have in germany and the netherlands because of this for one thing they dont have the money. And then its simply not realistic to build dikes along the entire coast. So even if the sea level rose by just 50 centimeters millions of people would be affected by. 9 of the worlds 10 largest cities are expected to be threatened by rising sea levels by 2015 they will have to develop a Long Term Plan for adapting to the new reality. Through do you have to set a reasonable timeframe it could be 100 years but what is 100 years in the grand scheme of things you have to have a magination off like our ancestors who built cathedrals the sons of those architects and stone masons never saw the completed project that their fathers had begun or the grandchildren didnt either but they had a vision for the future you have to have that vision for the future is just a brief period of time in the course of Human Evolution 100 or even 500 years Means Nothing centuries ago people used to take a long term view. One of these long term projects is Jacques Rouge design for a Floating City off the Pacific Island of tot he. The u. S. Based Seasteading Institute has developed a concept for a Floating City project led by political theorist pantry friedman the cofounder of pay pal is also on board the idea has a political dimension the silver and ocean colonies would be free from state control. But floating communities must be available to everyone not just the wealthy the oceanic project is being developed in coordination with the United Nations the goal is to make floating cities available to the many coastal regions that are under threat. Those solutions are urgently needed nearly half of the worlds population lives within 100 kilometers of the coastline. Oceanic cities could grow and adapt housing anywhere from 30210000 people. The threat of rising sea levels might be right around the corner hamburg in northern germany could also be at risk. That the homework is and its a real danger hamburg is located just 100 kilometers from the coast. And Research Indicates that if the sea level in 10 used to rise the risk of storm surges would increase significantly broadly through the. News reels recalled a flood of 962 when a storm surge washed over the dikes and flood of the north sea coast about 100000 people lost their homes and hundreds of people were killed and thousands as women are dominoes. The storm destroyed dikes along several 100 kilometers of coastline hamburg was cut off for days local residents were scarcely able to cope and the situation today maybe even more dangerous because since 962. 00 the sea level here has risen by 20 centimeters. This is the port of hamburg more than 350000 people who live in this part of the city a still threatened by storm surges a lot of new projects are underway to protect them. This new prominent along the elbe a river also serves as a Flood Control structure it was designed by zaha hadid architects. The prominent rise is nearly 9 meters above the river. Homework. Pember is building a lot of new dikes to pass and it can be out by the authorities are doing what they can. But im not sure whether we can really protect ourselves against a major storm surges in the thinking here is bizarre for example the half and City District which was built on the site of the old horton is especially vulnerable if. Sea levels were to rise by several meters i doubt we could prevent flooding there. Called to threaten. If water levels in the north sea continue to rise london my also be affected. Golson it will pour into we many large cities are at risk and that includes london and if get off on all if sea levels rise by 2 meters i would assume that many parts of london would face Serious Problems for an extremely poor game of the comment about 9000000 people live in london which is located on the river thames about one 3rd of those residents live in the citys central districts along the river. The thames flows into the north sea but rising and falling time its still a faint river water levels in london. One 6th of the city lies in an area thats threatened by flooding rising sea levels would put more than a 1000000 people and 500000 buildings here at risk. Storm surges and floods have become more common in britain in late 2013 and early 2014 southern england was hit by a series of severe storms heavy rainfall caused widespread flooding and power cuts. And disrupted transport systems. In london the thames burst its banks and many people were forced to leave their homes. The thames barrier is designed to protect the floodplain that includes most of Greater London from times and storm surges that move in from the north sea. Its one of the Worlds Largest movable flung protection structures. The barrier consists of 10 huge steel gates that are usually submerged but can be raised into position in case of emergency. In my opinion the times barrier design in future is one of the best examples of adaptation now days its reaching the end of its lifetime and there have been extensive studies to extent the usability of the thames barrier there have been studies that have looked at a very wide range of scenarios up to for example rises of 4 metres but some studies predict an increase of 5 metres by 2100 the barrier was completed in the early 980. 00 s. When scientists were predicting a much smaller rise in sea levels but now reality is outstripping those projections. I think london can be protected there is a lot of investment london is a Big International hub so it will be protected no matter how well we protect a place like like that so a mega city or a cost and make a city there is always some risk remaining in case of failure defense failure and so this is something that is considered in the design and we should be prepared for. The barrier will need to be updated. Sea levels are rising faster than anticipated and london is at the forefront of planning for an uncertain future. Definitely london is setting the example for coastal megacities and its something that for cities that can be affected by call some flooding but there are other examples worldwide and for example the most modern invention. And of course Different Solutions will fit in different places. But few coastal regions have a huge barrier like this to protect them from storm surges if sea levels keep rising many communities could be left to make difficult decisions. Take it off when all the stuff munging than some areas may simply have to be abandoned. In parts of wales for example communities are realising theyre living on borrowed time when the local government dont have the money to pay for flood protection. And so people will have to start thinking about where theyre going to live 3040 or 50 years from now that. Floating homes like these in amsterdam could offer refuge in a crisis. In the event of an emergency for example you could move house boats to hard hit areas fairly quickly to provide people with temporary accommodations. So long for now most people here who live on the water do so because they want to. Youre so close to the water that you can actually go swimming or kayaking any time you want. A floating home is like an expansion of the city. Cities keep getting more densely populated and buildings keep getting taller for this but as a living space and her water is still largely untapped. In affluent communities Floating Homes are a lifestyle a way to bring nature into the city but they also often new ideas for adapting to Climate Change is going to introduce you can either work against the water by building bigger barriers and so forth with of water or you can work with the water and embrace it. And thats what were trying to do with this project. Come to work out what under the sea is coming toward us and we have no one to blame but ourselves we call into it if we hadnt pumped so many Greenhouse Gases and Carbon Dioxide into the atmosphere oh we wouldnt have this Global Warming and rising sea levels. Because so this really is a problem that we ourselves have created this. A week of. Doing the corona pandemic. Why not. The big paris fashion designers have gotten creative in the crisis.
