oh the thought. or the. former. drunken. cardiac. industry is controlling your thoughts on the great books of the 20th century. present a hoax is. crazy. george mason. welcome to the level $3000.00. this week we take out all crystal ball and check out the cities of the future just what will life be like in our world's urban centers in 205100 years we'll look at some of the fascinating ideas already being

developed and learn about new technologies and innovations as well as the work of some visionary architects. 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 pleasure banks have been seems closing. up this meanwhile has stayed constant like transportation costs and health. but rents and mortgage repayments have become significantly higher. housing is.

becoming increasingly on affordable for many and yet it's a basic human rights as laid out in article 11 of the un his 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. but living in album centers is often on affordable rising housing costs have become a flash point. 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. 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. 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 it's probably the most pressing social issue facing cities for sure around the world. says adequate housing is a human right something politicians often don't realize and investors often ignore the home for everyone affordable of a decent size and location. in the film 400 discusses with experts why this right is being disregarded more and more. you have human rights obligations and you can't let these investors and the financial system run amok on its own but i see it sells with bark and they deploy the law in ways that work that stuff is happening now. we have arrived at a moment when there isn't gaping holes. in our system. most

of our major international systems are that don't take the individual so seriously . this is billings crowds back district lively cosmopolitan in the center of the city it's especially popular with young people it's also changing for instance number 83 runners tosser was recently bought by an investor. but none of the tenants know what his plans are. carlos martinez originally from the united states lives here with his wife and children. and that $75.00 square metre flat has 2 rooms the kitchen and the bathroom. they pay less than $10.00 euros per square metre heat included that's not cheap for . the family is happy here. we know the people in the neighborhood we've

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 that's 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 didn't 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 coles or a norwegian investor and director of a network of companies he didn't answer our requests for an interview.

with rebecca bushnell has lived here for more than 30 years and has seen her neighborhood transformed. not very nice of course he'll raise the rents as much as he possibly can they always raise it to the maximum until it heads in a turbo capitalistic fashion. for me that means that soon when they say i'll 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 they're thinking square metres of living space and squeezing every square metre as much profit as they can so that is the extractive industry of high finance that has moved into an area that happens to be in fact a human right and that's the rub. the residents of the apartment building in crisis back are ready to put up a fight they've named the activist group in memory of village town former landlord

. housing demonstrations they march with tenants from other buildings facing the same situation. for 20 sports this process of displacement is really an anonymous one. it simply happens one building after the next discourse up on the street the tenants are squeezed out on the outside it's 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. cam of real estate sector change its thinking and approach. i never think about. that it's 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 i'm on the winning side here that's for sure that that's for sure. of course no one knows exactly what the cities of the future will be like though one thing's for certain they'll be felt the un says that by 2052 thirds of the global population will live in cities traffic streams and commute his 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 dough in south korea. the south korean capital seoul is a teeming metropolis of 10000000 a finance hub and center for the arts there's plenty of tradition here but not much

scope for large scale urban development. that's taking place 40 kilometers to the west some go international business district is being built from the ground up on 6 where kilometers of reclaimed land. it's been billed as the smart city of the 21st century and 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 it's 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 it's all being tracked and can be adjusted individual

that residents can monitor and reduce their consumption municipal staff can optimize the use of resources. they see power consumption at every note and can match production to demand. the garbage disposal system is also extremely clever trash from apartment buildings and offices travels via chutes and pipes straight to processing plants. the system regulates who may discard what kind of garbage at what time. this market city only functions thanks to the digital network and because it's monitoring isn't there also a risk of unwanted surveillance. of 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 landmarks across the beautiful old city. and energy saving streetlights that only get brighter when people are nearby for all this to work people's 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 people's lives easier and better but we have to make sure it doesn't lead to total surveillance and control. technologies that one saying there's a 70 architecture today's housing policies are often about getting apartments belts as quickly and cheaply as possible to get

a handle on the icky show teaches them that so many architects that simply it seem that elevation they want sustainable buildings and a radical rethinking of priorities. the 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 the construction are said to contribute up to 40 percent of energy related carbon emissions. architect has been designing sustainable functional buildings for over 20 years. he says they're 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 you put in a lot of plans long and becomes clean which is not so in

a green building it's actually green because it respects meters and it. kind of uses replenishable sources resources and reduces various stages of uses consumption and we recycle a lot of materials. one of the world's designs in new delhi is famous for being india's 1st 5 star rated green residential building called green one. it's 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 india's hot sun is. the building also generates when you pull energy and harvests rainwater. it's 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 10 percent more or 15 percent more and after 5 years it pays for itself and then after that did runs virtually free of cost and you are giving back to the future generations you're 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 that's the need of the are right now. at the moment india has around $1400000.00 modern homes built with a green concept which amounts to less than 5 percent of all residential properties . the indian green building council 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 al gore instructors that history has to be studied because historically what people have. bit naturally it is known that they are the best structures and that what we do is we can temporize it. while renovated his own house in 2000 he was inspired by the traditional methods of environmentally friendly construction. i used all the broken pennies that came out from the toilets so all that were broken and used in the form of a packer and since a lot of them were laid killer tails it reflects a lot of peter's 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 enable before you want a system that will lend green building so i think the consciousness has come in and . or not this will really pick up but i am sure that this. situation we have been receiving a lot of calls from clients saying that does simply fire homes let us give more open areas let's reduce the built up area let's go in for more green measures let's go in plant more trees because they help in you know taking care of pollution as well. is green building design the wave of 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 we keep the cities of the future. in 2016 the world's households produced 2000000000 tons of waste by 2050 estimates suggest i'll be 3400000000 tons of it 80 percent from cities. so most of us rubbish is just a pain it looks bad smells bad and yet it has huge potential clever recycling we can make it stream lee useful products from it like in the netherlands. we are using natural resources at a very fast pace some are finite others renewable but nature can't keep up with us . we also generate vast amounts of greenhouse. cities account for

70 percent of them. the dutch capital amsterdam is aiming to create a circular economy by 2050 that involves containing the use of new rule materials avoiding waste and reusing as much as possible that 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 2 thirds of all the plastic in the ocean actually traveled by our rivers to our sea ocean and quite some trash that you see on the street or that this is there and in this rivers and then of course the rivers flow to work to see you so it's one of the kind of transport and magnus magnusson plastic pollution and that's why we would really like to stop it there a memory of elaine's is behind us start up the great bubble barrier and it's in a for to technology here's how it works

a chub is laid across the bed of the waterway air is pumped out of poles 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 it's a pilot project but the potential both in the city and world white this enormous. you have multiple sectors that have interest in this for example you can imagine the companies that have a benefit of tourists coming by they want beaches that are clean they want riverside's that are clean they want to have terraces where you can see all nicely

and on the moment you install such such a system. and you can you can make it can you make sure that it looks nice to visit again the firm has received financial support from the government it's 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 gum may call cow mera which has many operations as a glue opined an agent in the manufacturing and construction industries. but if you want to have a circular society to an insurance that cycle all our waste streams and waste water is a very important way streams and nowadays what happens if you are in the end produced by a gas whether it's with bio gas a relatively low failure application and then producing this caught me and i just

do we can use this before i feel you have thicker shirts so what we want to do in the hands of grams of produce i show you building material for using waste far from a certain. standard industrial pleas 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 tons of it a year. and this research is a working on new bio degradable materials. they mix cow marrow with recycled toilet paper and various combinations of peach pits and. shells. so far they've made great signs undeveloped architectural cleansing material 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 but prospects look good. for infrastructure hardwoods that's b. to bore by this material and also aluminum and now the ministry huge markets with aluminum has a very very high c o 2 footprint and a good thing of this material if you can beat it's all mechanical properties and to property if you. don't the price will be the challenge and i think the co-op coming to new years we will try to replace aluminum by the skull near accomplish that material. recycling and up cycling organic waste and construction waste could be a money spinner and would certainly be good for the environment. spend known as a great place for emissions for recycling for decades it's still a long way from achieving a circular economy. the plan is to make that happen by 2050 and ambitious goal 1st

city to time and to be a pioneer. and now we leave technology behind us and head out to the mexican countryside. 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. it's where i like to be. this is my mother in law and this is my sister in law. i like it when they come visit. me my eldest daughter is 16 her name is maria guadalupe. my other daughter in

law is 15. uni that's miguel. and that's jose luis i have 5 children that's my nephew. this is a war i make tortillas. and i enjoy working in the kitchen and do everything by hand here. so when. when my family are out all day i get up at 3 in the morning to make them tortillas for lunch. and they had a look at that they have a making of the and then i make some more that we eat hot for supper i make tortillas twice a day. here they are.
