the idea is a business way to bring you more conservation. how do we make cities cleaner how can we protect our towns what to do with all our waste. we can make a difference by choosing smaller solutions overstrained said you know what are you saying. the idea is for the a series of the business goals of the long. welcome to global 3000. 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 as we 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 dick 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 activities closing in. 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's a basic human rights as laid out in article 11 of the un's covenant on social rights the state parties to the present covenant 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 urban 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. they learn a flood 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 and she speaks with politicians investors tenants associations and with people experiencing displacement. and speculate 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 a home for everyone affordable of a decent size and location. in the film family discusses with experts why this right is being disregarded more and more. you have human rights obligation you see and you can't let these investors and the financial system run amok on its own but i see in cells with bark and they deploy the law in ways that work for 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 or 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 over. that $75.00 square metre flat has 2 rooms a kitchen and a bathroom. they pay less than $10.00 euros per square meter heat included that's not cheap. 8 the family is happy here. we know the people in the

neighborhood we've seen their children grow up and are 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 their neighborhood like so many others in berlin. the building's 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 of the building eventual he ended up on the open market. it was bought by henry coles a norwegian investor and director of a network of companies didn't answer our requests for an interview.

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 it possibly can they always raise it to the maximum until it heads in a turbo capitalistic fashion. for me that means that sooner or later i'll be gentrified out of hair. the whole business model is based on the idea of taking square metres of living space and you have to 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 really their former.

landlords. housing demonstrations they march with tenants from other buildings facing the same situation. as a federal sports this process of displacement is really an anonymous one it simply happens one building off to the next to schools hop on the street the tenants are squeezed out on the outside it's not visible at all unless people get organized. says 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 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 full the un 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 kyoto 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 song go international business district is being built from the ground up on 6th where kilometers of reclaimed land. it's been billed as the smart city of the 21st century and your body's 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 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 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. 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 this is so architecture that today's housing policies are often about getting a top men's belts as quickly and cheaply as possible to get

a handle on the kids show teaches them that so many i'll get texts that sticky to naturalization 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 in 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 a lot of green plants you put in a lot of plans long and becomes green which is not so in

a green building it's actually green because it respects nature and it. kind of uses the replenishable sources resources and reduces the state of uses consumption and we release a kill 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 renewable 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 bin percent more or 15 percent more and after 5 years it pays for itself and then after that it 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 0 carbon exit or 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 modern homes built with the 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 or instructive history has to be studied because historically what people have big naturally it is known that they are the best structures and that what we do is very contemporary. but while renovated his own house in 2000 he was inspired by the traditional methods of environmentally friendly construction. i used all the broken barriers that came out from the toilet so all that were broken and used in the form of a back to and since a lot of them were laid 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 sustainability has to start from and you have to adopt a 1st enabled before you want a system that will lend green building so i think the consciousness has come in and pandemic or not this will 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. give more open areas let's reduce the build up area let's go in for more green measures let's go in plant more trees because they help you not 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 at least 3400000000 tons of it 80 percent from city. to some most of us rubbish is just a pain it looks bad smells bad and yet it has huge potential through clever recycling we can make extremely 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 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 reverse towards the ocean and quite some trash that you see on the street or that this is there and up 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 is of plastic pollution and that's why we would really like to stop it there america ever lanes is behind us start up the great bubble barrier and it's ineffective 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 worldwide is enormous. you have multiple factors 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 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 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 society the insurance that cycle all our waste streams and waste water is a very important way streams and nowadays what happens is i think in the end produce bio gas whether it's with bio gas

a relatively low failure application and then producing discovery and i just don't know we can use this before i feel you have your shirts so what we want to do in the ante room temperature i show you building material for the ships using ways far from the sorts of. standard industrial planes are made from oil which is not good for the environment. in the new process bacteria purify the waste water. cameras a side benefit a single plant can produce up to $800.00 tons 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 almond and pistachio 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 comair and toilet paper can come to market the prospects look good. for infrastructure hardwoods that's b. to bore by this material and also aluminum and how 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 build it anyway so then the price will be the challenge and i think the co-op coming through in years we will try to replace aluminum by discovery or composite material. recycling an up slightly organic waste and construction waste could be a money spent 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 determined 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 young. my other daughter

is 15. that's me girl. you know and that's why i have 5 children that's my nephew. this is a war i make tortillas. i enjoy working in the kitchen and do everything by hand here. when my family are out all day i get up at 3 in the morning to make them tortillas for lunch. then i make some more that week hot for supper i make tortillas twice a day and. here they are.

thank you for coming to see us. anyway a young girl. and now it's time for us to say goodbye to you thanks for watching we'd love to hear from you and you can e-mail us at global 3070 dot com see you next week.
