All of which raises a central question who will actually be able to afford to live in the city of the future according to the i. M. F. Slobo house price index over the past 20 years prices have risen and risen with a small dip just after the financial crisis. Over the last 10 years the cost of many essentials in o. E. C. D. Countries has gone down food for example leisure activities closing. Others meanwhile the state constant like transportation costs and health. But rent and mortgage repayments have become significantly higher. Housing is becoming increasingly on affordable for many and yet it is a basic human rights as laid out in article 11 of the un says covenant on social rights. The state parties to the present government to recognize the right of everyone to an adequate standard of living for himself and his family including adequate food clothing and housing. We met an activist who never tires of reminding society of this. The world cities are drawing people like magnets. Living in album centers is often an affordable rising housing costs have become a flashpoint. The Global Real Estate market has long since become disconnected from its function of providing people with places to live real estate is an investment a commodity an object of speculation of profit. In germany alone 2000000 apartments of homes stand empty that just speculative investments. They learn a farmer says the system is flawed until recently the canadian was the un special rapporteur on adequate housing. She features in a recent documentary which shows her as she travels the world to get to the bottom of the housing crisis. She speaks with politicians investors tenants associations and with people experiencing displacement all education and speculate her un mandate ended in april 2020. Is still pursuing the issue she now runs her own organization from her home in ottawa. The right adequate housing is the right to live somewhere with Peace Security and dignity and i actually think its probably the most pressing social issue facing cities for sure around the world. Says adequate high. It is a human right something politicians often dont realize and investors often ignore a home for everyone affordable of a decent size and location. In the film 500 discusses with experts why this right is being disregarded more and more. You have human rights obligations and you cant let these investors and the Financial System run amok on its own but i see cells with bark and they deploy the norm in ways that work that stuff is happening in our. We have arrived at a moment when there isnt gaping hole. In our system. Most of our Major International systems or dont take the individual so seriously. This is billings crowds back district lively cosmopolitan in the center of the city its especially popular with young people its also changing for instance number 83 carter was recently bought by an investor. But none of the tenants know what his plans are. For the. Car lost martinez originally from the United States lives here with his wife and children. That 75. 00 square metre flat has 2 rooms a kitchen and a bathroom. They pay less than 10. 00 euros per square metre heat included thats not cheap for. The family is happy here. We know the people in the neighborhood weve seen their children grow up and now we have our own children and we. We just would like to stay here. Will the new owner renovate the building raise the rents and put the individual apartments up for sale thats a common strategy the courtyard has become a Meeting Place everyone here is worried will they be forced to leave the neighborhood like so many others in berlin. The buildings previous owner who passed away in 2016 didnt want the building to be sold but his will was declared invalid due to formal irregularities the building eventual ended up on the open market. It was bought by henry calls for a norwegian investor and director of a network of companies he didnt answer our requests for an interview. With Rebecca Bushnell has lived here for more than 30 years and has seen her neighborhood transformed. Not true of course hell raise the rents as much as he possibly can that always raise it to the maximum until it heads in a turbo capitalistic fashion. For me that means that soon when they say ill be gentrified out of here. The whole Business Model is based on the idea of taking square metres of living space and you have i mean this is how theyre thinking square metres of living space and squeezing every square meter as much profit as they can so badly is the extractive industry of high finance that has moved into an area that happens to be in fact a human right and thats the rub. The residents of the Apartment Building in crisis back are ready to put up a fight theyve named the activist group in memory of really tough former landlord. At housing demonstrations they march with tenants from other buildings facing the same situation. As a federal sports this process of disk. Basement is really an Anonymous One but it simply happens one building after the next is brought up on the street the tenants are squeezed out on the outside its not visible at all unless people get organized. Learning farces much more public debate is needed as well as pressure on politicians and investors including legal action. Will that work. Can the real estate sector change its thinking and approach. I never think about. That its not possible i think because what is stronger than human rights i believe in the strength of human rights against all of the these are just human beings with greed so im on the winning side here thats for sure that thats for sure. Of course no one knows exactly what the cities of the future will be like though one things to certain theyll be fulfilled the u. N. Says that by 2052 thirds of the global population will live in cities traffic streams of commuters pollution some Big Solutions and needed the smart city model could be one of them such cities a digitally organized and highly efficient and there are already places offering a taste of this future kioto in japan and some does in south korea. The south korean capital seoul is a teeming metropolis of 10000000 a finance hub and center for the arts theres plenty of tradition here but not much scope for large scale urban development. Thats taking place 40 kilometers to the west some go International Business district is being built from the ground up on 6th where kilometers of reclaimed land. Its been billed as the smart city of the 21st century and young bodies pioneering work on the part of architects Construction Companies environmental and high tech firms and Computer Network experts. This model city is overseen and run by a giant Computer System its the brains of the city all public buildings and homes are equipped with digital sensors and controls that can be operated remotely and are monitored centrally. Sensors relay rooms temperature and energy its all being tracked and can be adjusted individual that residents can monitor and reduce their consumption unisa bill staff can optimize the use of resources. They see power consumption at every node and can match production to demand. The Garbage Disposal system is also extremely clever trash from Apartment Buildings and offices travels via sheets in pipes straight to processing plants. The system regulates who may discard what kind of garbage at what time. This smart city only functions thanks to the digital networking recordist monitoring isnt there also a risk of unwanted surveillance. Personal data could prove to be the most valuable product generated in a smart city because they are the basis for targeted information or advertising. In kyoto japan u. S. Technology group cisco is working on smart city solutions. Managing the flows of tourists to and march across the beautiful old city. And Energy Saving streetlights that only get brighter when people are nearby for all this to work peoples behavior and movements have to be captured with the help of surveillance cameras. But what if facial Recognition Software were added to the mix and if interactive information panels were to collect data to generate profiles of particular individuals Smart City Technology should make peoples lives easier and better but we have to make sure it doesnt lead to total surveillance and control. Technologies that one saying theres a side architecture todays housing policies are often about getting apartments belts as quickly and cheaply as possible to get a handle on the icky chill teaches them that so many all get texts that simply too narrow elevation they want sustainable buildings and a radical rethinking of priorities. New delhi skyline is a mixture of modern skyscrapers and Energy Intensive poorly designed constructions Carbon Emissions from buildings are often neglected in the climate debate but in India Buildings alone and they construction are said to contribute up to 40 percent in Energy RelatedCarbon Emissions. Architect has been designing sustainable functional buildings for over 20 years. He says theyre more urgently needed than ever but there are still a lot of misconceptions about what Green Building design really means. The biggest myth is that people believe that a green home is one that has a lot of green plants put in a lot of plans and it becomes cream which is not so in the Green Building its actually green because it respects nature and it. Kind of uses the replenishable sources resources and reduces restated reduces consumption and we recycle a lot of materials. One of the worlds designs in new delhi is famous for being indias 1st 5 star rated Green Residential building called green one its been certified by the research and policy organization the energy and resources institute. Large windows provide lots of Natural Light while Double Glazing a relatively new feature in india insulates the building keeping it cool in indias hot summers. The building also generates Renewable Energy and harvests rainwater. Its able to capture 75 percent of its was in needs and also saves lots of electricity. It costs more to build this way but these features pay off over time. I think it is still worth it if you spend bin percent more or 15 percent more and after 5 years it base for itself and then after that it runs virtually free of cost and you are giving back to the future generations youre giving back to the environment we are now coming into the concept of you know 00 buildings which are going to you know give back more than they consume i think thats the need of the are right now. At the moment india has around 1400000. 00 modern homes built with the green concept which amounts to less than 5 percent of all residential properties. The indian Green BuildingCouncil Hopes to take this number to 10 percent in the next 2 years and some states have begun providing more incentives to green certified construction. However these figures do not include the countless houses built by hand in rural india traditional dwellings that are often green in their own right. With inspired by or instructive history has to be studied because historically what people have built naturally it is normal that they are the best structures and that what we do is very contemporary is it. But one renovated his own house in 2000 he was inspired by the traditional methods of environmentally friendly construction. I used all the broken pane of that came out from the toilet so all that were broken and used in the form of a back burn and since a lot of them were laid days it reflects a lot of heaters very. More people can now afford the initial investment and more indians are growing aware of the impact of their choices on the environment. They strongly feel that just inability has to start from and you have to adopt a 1st in a below before you want a system that will lend Green Building so i think the consciousness has come in and pandemic or not this really pick up but i am sure that this. Situation we have been receiving a lot of calls from claim saying that does simply fire homes let us give more open areas lets reduce the build up area lets go in for more green measures lets go in plant more trees because they help in you know taking care of pollution as well. Is Green Building designed the way for the future in india architects like milan john but while hope so and are ready to play their part. Rethinking cities is a mammoth task with heaps of challenges how for example will be keep the cities of the future. In 2016 the worlds households produced 2000000000 tons of waste by 2050 estimates suggest ill be 3400000000 tons of it 80 percent from cities. So most of us rubbish its just a pain it looks bad smells bad and yet it has huge potential clever recycling we can make extremely useful products from it like in the netherlands. Were using Natural Resources at a very fast pace some are finite others renewable but nature cant keep up with us. We also generate vast amounts of greenhouse. Sconces cities account for 70 percent of them the dutch capital amsterdam is aiming to create a circular economy by 2050 that involves kid tailing the use of new rule materials avoiding waste and reusing as much as possible by slashing emissions. The City Sanitation Department fishes 42. 00 tons of floating plastic trash out of the canals every year a lot more probably gets through. We never got around to ferrets of all the plastic in the ocean actually traveled by every verse towards the ocean and quite some trash you see on the street or this is there and up in this rivers and then of course the rivers flow to work to see you so its one of them of transport and Magnus Magnusson plastic pollution and thats why we would really like to stop it there a memory of elaines is behind us start up the great vocal barrier and its indicative technology heres how it works a chub is laid across the bed of the waterway air is pumped out of holes along it the bubbles drive trash in the water to the surface towards the bank and into a receptacles. Tests have shown that on average 86 percent of trash in the water can be collected in this way. The garbage that ends up in the container is removed 3 times a week. For now only one bubble barrier has been installed in amsterdam its a Pilot Project but the potential both in the city and world white is enormous. You have multiple sectors that have interest in this for example you can imagine that companies that have a benefit of tourists coming by they want beaches that are clean they want riversides that are clean they want to have terraces where you can fit on nicely and on the moment to install such a system. And you can you can make its make sure that it looks nice to visit again the firm has received Financial Support from the government its also working on ways to recycle all the collected trash. Cities also generate lots of waste water as unlikely as it might seem the water flushed down our toilets contains valuable resources that could be retrieved. Scientists in the netherlands have developed a new waste Water Purification system to do just that. One of the end products is a gun may call cow mera which has many up locations as a glue or binding agent in the manufacturing and construction industries. But if you want to have a circular siding to insurance go all our waste streams and waste waters are very important where streams and nowadays what happens if they are in the end produced by a gas whether its with bio gas a relatively low failure application and that producing discovery and i just dont know we can use this before i feel you i think i should just show what we want to do in the ante Room Temperature i show you Building Material sort of using waste water from the streets of. Standard Industrial Police are made from oil which is not good for the environment. In the new process bacteria purify the waste water. Comair is a side benefit a single plant can produce up to 800. 00 tonnes of us a year. In the slop research as a working on new bio degradable materials. They mix cow marrow with recycled toilet paper and various combinations of peach pits and almonds and pistachios shells. So far theyve made great signs and developed architectural cleansing materials made out of 80 percent organic materials. More r. And d. Is needed before this new composite based on cow merit and toilet paper can come to market the prospects look good. For infrastructure hardwoods thats b. To bore by this material and also aluminum and other media is a huge market with aluminum has a very very high c o 2 footprint and a good thing of this material if you can beat its all mechanical properties and also here to property if you build it anyway so then the price will be the challenge and i think the coop coming 10 years we will try to replace aluminum body discovered mirror composite material. Recycling and up cycling organic waste and construction waste could be a money spinner and would certainly be good for the environment. Spent known as a great place for emissions for recycling for decades its still a long way from achieving a circular economy. The plan is to make that happen by 2050 and ambitious goal for a city determined to be a pioneer. And now we leave Technology Behind us and head out to the mexican country signs. To meet a Family Living much like the generations before them. Hello my name is. I spend most of my time here in the kitchen. Its where i like to be.
