are we getting? oh, we have an exponential growth in bullshit. how can we feed every one doesn't mean we don't want to chase climate change with our food supply? questions for the present or future heads filled with ideas. when we learn something, the hardware and software brain changes games. so get ready for the brain update. 40 to the answer to everything starts january 15th on dw with we're all used to the streets of our cities being hectic. smelly and noisy always hath been, always will be right. it's up to us to find our way through the traffic. what other options do we have? more than half of us now live in cities that are getting ever more crowded

for generations, cities have been built for cars, not people, causing traffic jams and pollution. many cities are already very unhealthy, and the climate crisis could make them unlivable within our lifetime. some people say we can rethink the cities we live in and make them better with. but what does that actually mean? how could we reclaim and re use our own cities to make them cooler and cleaner, and us happier and healthier group? we're about to see how some cities in europe are finding solutions to their own urban issues. the french capital paris is experiencing a new revolution on its streets. barcelona in spain is making the most of the city's unique design to revitalize itself at both cities. a learning a lot from this place haunting and in the netherlands. i

think you might think the netherlands is far too obvious, a choice to start exploring people friendly streets. but do you know how hard dutch people had to fight for them these moments of change have never been easy. and many people think that in the netherlands, this always was the case, but also in the netherlands, it took radical change like literally urban warfare and the 1970s of people going through the streets and demand the streets back. so in the netherlands, you had the movement that was called stop the child murder in the 9th and seventy's . and that movement really managed to get people to weekly in the streets that at that time, what really engineered towards providing more space. because this is marco to promote strict aka the cycling professor. he had the faculty of urban mobility futures at the university of amsterdam continental as the next generation of urban planners in land use and mobility. what is missing in our current conversation

about rethinking urban transportation planning? market also, she has a lot of ideas on social media about how we use our cities. the streets in our cities always were the remaining space between buildings and in the remaining space between billings, everything happens. social life happens. trading happens, children could play people with me. and people who traveled through for this change radically in the 1920s, 100 years ago. and that was the pressure that was introduced by the motorized vehicle cars came in large numbers to that street and basically put pressure on the way that we were thinking about the 3, the literally colliding with all these other purposes that were happening in experts and to respond to that a whole new domain of thinking was introduced for traffic engineering. sort of was born in the 19th thirty's and developed the language around seeing streets of places where people want to go as fast as possible as individuals. and because of that, it started to solidify into institution and into loss. if it behavior it's solidified

into concrete, asphalt and technology. and finally, it solidifies our imagination, or we now take it for granted that we think about the streets as places that are primarily there for vehicular throughput. the way that we develop the streets with his logic makes our streets unsustainable. unlivable unsafe, and maybe even unjust. so we don't think about streets as places in terms of justice, and that's how we thought about them until the 1900 twenty's. they are no longer a place where our children can play or can find out how they autonomy. lee can go through the city and become an adult citizen. and this is something that society now slowly starting to realize that this is unacceptable. we need new narrative and as soon as you start using them, we see that people suddenly start seeing the street for what it really is. and they start understanding that they are something to fight for. i think there is a political or societal movement of people that are sort of wakening up to this idea that you can actually tell different stories and different narratives. like for instance, shifting from we are closing streets off for one day. instead of that saying,

we are opening streets for one day and suddenly we see what that does with people are that people start realizing or wait a minute. we have been accepting our language or narratives about the streets. what if we challenge them? and i think that we see globally, this movement slowly gathering momentum and now what it needs to sort of a couple of seeds of places that show what can happen if you really recapture that narrative. one person already planting seeds is yan kaminsky. his animations invite the viewer to imagine how streets could look if space for cause was replaced with space for people, for young sharing these utopian visions is a playful way to question how we think about al cities are no longer wanted to wait for the increasingly urgent social change, but to make a contribution myself and as a communication designer, i decided to make streets without cause visible. and i realized that there was so much space to aid and show possibilities of what we could do with the streets

without calf ah, bicycles or feet. as the dutch pulled them a key to sustainable city concepts. we asked the cycling professor to explain how the netherlands and m to them is a good example of what happens if cycling gets respected. place at the table of traffic engineering and what they show us. because what happens if you take cyclists are human behavior as a central element in design, instead of how can you make humans behave according to your design and, and answer them. we have some places where we experimented with what happens if you eradicate the traffic light logic on an intersection. ah, so they didn't, the section was redesigned because there was so many cyclists compared to god

drivers that the municipality considered. what would happen if we take out the traffic light and the traffic lights actually, and sure, does god drive as good go through, but didn't really make it safer. so they did it best. they took out the traffic lights. and one of the peculiar findings of the elderly that did it was if you take out the traffic lights, people start to behave like active citizens. again, they are not looking at the light, but they're looking at each other and negotiating with each other. how to use the intersection of course amsterdam could have turned out rather differently if they hadn't blocked us in spite city may cavers like the car 1st joking and plan the 1960 of the dutch cities like trash has been rolling back call centric planning goodbye urban highway. welcome back. originals to to canal. ah. then there's hunting and it chose human centered planning in the and cheese and is

now ranked is one of the happiest places in the world. we met 2 of the people responsible for keeping it that way. they can seventies the center of crowning, it was totally different today, the central part of the city. it felt monica, our central last square, is, was to place where at garza driving around when you went from the south of frauding into the north of in the province. in the seventy's, we decided that has to stop. we choose to make a city traffic plan where our center was divided in 4 parts and where it was not possible to move from the one party daughter with a car already with food or bag. it was a totally new concept of thinking about, or city war, one of the 1st cities in europe to rethink that use of the city center, a concept in paris. i think it's a way we design our city already. the concept that in 50 minutes you have to reach your work, your school, your roots, your center, reach your shops, it's the way we designed the last 25 years. our city center,

this example embarrass on a frowning and it's very useful for a lot of shady should euro, but also are now central hunting and has been come to city manages i in good boys attending their attention to be out scanned. this is the beta my back. i see that a very functional design. there are a lot of concrete lames for the car. there are side roads with a lot of got bogging and our sidewalks were the logo, bicycle barking. so we see a lot of opportunities for chains. there are 2 neighborhoods which are divided by this road. so we want to bring the neighborhoods together for public space. we made this an example for how the city could look like. ah, if only only made a choice to make more space in our streets for green, more space for people. so the consequences that we have less space hooker, and that's not always, it's easy choice because a lot of people also

a holding and are dependent of the car. also a lot of people like to see the car in front of their house, but what we do is ask the people what kind of 331, and that's a different question then. where do you want to park your car? well then everyone says for now in front of our house and i don't want to pay for it. that's what everyone who owns a car will say, we ask what kind of cd? and a lot of people say, are we like to see a street where children can play with there are some trees or it's nice and easy to meet your neighbor. and when you start with that question, the discussion will check. what is people in other cities were asked what kind of streets they want that's already happening elsewhere in europe. waste between the mediterranean sea and the mountains. buffalo now has the highest condensate, one of the highest population densities in europe. but thanks to a clerk of 19th century planning, this iconic european city is undergoing its own special transformation. the city government wants to convert a 1000000 square meters of road surface innerspace for local people in the cities.

unique grid path dates back to 859 and the pre call era designed by funds for this layout is the key to barcelona plans. groups of individual block a close to 3 traffic and in hunting and they remain open for local use and for commercial and emergency name alone basically build their super blocks idea on that idea of, of 40 years ago. the idea that you can still allow contracted to go everywhere as long as you lower speeds of cars and you don't allow through traffic. so much of the traffic you will find is not necessary. and traffic that is necessary can still go to places where they want to be. but as soon as you do that, you start unlocking that street for the people that lived there, they suddenly realized how much space they actually reclaimed. how much space to now have to sit, commit each other and how much space and freedom the children suddenly have if there is no longer god traffic everywhere. and it also frees up the parents because

no longer have to shop for the children everywhere because they are much less danger around. we visited a super block santini market. they're actually known locally as to buddy, as all super islands, which seems to fit better. that originated salvador ada told us that the goal was to cut traffic and noise pollution without camping down on call use the customer of our loaner model. ok. i'm or she said yeah, go to the pin for that is hopefully going that he got a movie that goes on solo. is the policy until they go to discuss the marquis call it's this patio is not bluff. are piano? is it online? that's a key on the car. yes. you know, they go to configure a new rod again or they've either look, i said that i thought it all the last a few of our not for them. this are yeah to say. and today your loyal coil of me in your spare time be another enter. any mentor or her and it under gambled manifesto

fiona is full doodle is out of these because there are there you're fuel on always from the point is arianne told us was that it does not fall. i meant it as the best plan for me until a new generation in barcelona is growing up, knowing that the streets can belong to everyone, thanks to the bt books or bite the bus every friday, the children cycle to school with traffic stopped on their lives with me, when can i mean? yes, but i mean we have nbc se really was cookies and on this cold winter's day in barcelona, most people asking about we're happy about the changes i think grades to our safe space it out or you can kind of, you, people are like me really woke and just enjoy the think it was i was like i'm with said so guess i'm on to still get

a good afternoon and i will is inconvenient because im directors loads but if you're certain somebody orders less so little a few less much really the 1st one is a rescue. several speedometer must be the out. i can one bit. janet fans is barcelona, is deputy math for ecology, albinism, and mobility. she says the success of pilot projects inspired her team to think big points here. normally the n get, i'm of the talk parking lot all about. hello. not again. not all. i filled out pretty much the number of skill. yes, ms. brenda selma. god bless. i mean, they couldn't look a dinner good, but i must ask, i yours is blackened the thing almost as puffy when i come in out, but i who are to put a stop or by the salary. i'd like to hear i was again only goes, but it didn't go to matters by people out there for the legal aid in particular that you put more well know, seaford and the government is prioritizing community participation. but vocal critics remain by ago, runs a portia garage in downtown barcelona,

and misses the freedom to drive anyone with when he's more with it glossy on black, the gum, and the benefit not on lack of quality steady. are you not linear, cassandra, who found that it's a scary to any welcome to her brother la kenneth when we do any flaws, writers allotted and enough from up north africa. they took the afternoon with us and wendy single minute of moustache profound and not angry. nadia heads the barcelona tourism association and isn't happy with the planning process of the good luck with emma's has not been out of pocket in the day. so if anybody has mickland m e at yahoo dot com la lithonian, don't everybody get kitten asi jenny? she get on my left bed to see alaska must be new though they're hidden in a federal case. 24 miserably. but 7 on the go to the indian candy when you got in the front of my fin assembly at home or not. a thing is if you haven't already moved up and they've gone gone platform of the city, government is convinced it has enough public banking and is pushing on on the 15th

from what i'm going to go to school some of the way up there or not. but a thin throat than that. yes, boy, last new truck and maybe be in the little gimmick. i'm the up master. i support the bully for manual school. just going by milan. there's the kid by the lose me off hitting the spin. fabulous. because his mother and me will and go to china and make well, i'm not gonna come in under yama wasena garbage if is the middle school just catch up with our niece thus? yes or so pretty young fellow. now guy, years, them there law, him vision for the one in stock last quarter, sawn now had been the dad marco to bremar's straight seized barcelona, facing the same debates as dutch cities in the seventy's and 80. so what we see in all these changes in general in change is that people resist and we have to take that seriously because they resist because some people will lose something. again, the example of children children have been losing their freedom for decades, but they don't have a voice for the people that will currently lose. well, 1st of all, their loss will be relatively small as receive for many examples. we still have to

allocate the traffic require for people that really need it. but all the other pieces are lost. so that the freedom to go through a city with your personal private vehicle as fast as possible. yeah, you will lose them. but because of that so many others and even yourself, you will win so much as well. we need to unlock all these people that currently don't have the voice and the silent majority that sexually losing out already. for decades, the parents are so inspiring for us because it shows that if you develop a new narrative, it can actually convince people. but the narrative should not be about scars versus by. it should really be about the deeper values that people have an a 15 minute city gives us this narrative. it talks about a meaningful life that is not requiring fast mobility. this means that the relation that citizens have with the street with the city would shudder, can radically change more about the 15 minutes later, 1st wide. and it became mer of paris in 2014. with her pledge to make the

capital more livable. parisians were ready for change after years of deadly summer heat. why should parents be so under threat from rising temperatures for roxanne menu of the capital climate academy? it's down to typically that he designed the heat ways or more whole in density center such as paris because of the urban sheet island effect, which is basically the fact that in the centers the temperature was higher than in the surrounding countryside. this effect is due to a very effective and a lot have been can be linked to landing and how the city is evolving and his designed in paris, especially we have very narrow streets and often high buildings. so the on res, reflect a lot on various offices and that accentuate the increasing temperatures. this also means that you have less wind, and we need windfall, cooling effects, the green areas, and the what, how much is a quite scarce in urban settings and in paris in particular. so it adds to the

sheet effects, of course she, the mission which are directed you to human activity such as the emissions from google, from industries. so many of these causes it can actually be tackled by different urban planning. few people know the streets of paris better than i. it is a cyclist to broadcast his rides, live on twitch and keeps his social media followers up to date with the changes i just took us on a bike, right? to see what had happened in the french capital over the last 8 years. with ethan download through doug or not, who led the thing like that to do it? if it's walking or not on when it's walk, it turns when he's not walking comes on to do i know so, so, so here we are in the neighborhood on you can see no, all of his place. it full lighting by by before it was everywhere on that all. but

i didn't do grief, alina auto expense for this place. i don't know it very nice place to work with . so here we are in love. i see. yeah. you have to imagine before all of this place. it's voc jaw can pause here for turning all a wrong to stay so nobody will generally walk or leave nozik just we move that's on . you can just, andre is place for leave. now from here you can see we have to pull a thinner on this place was only for thought knows essentially physical difficulty

on only. but if you're on taking on new things, bringing a lot of life the idea of creating many centers within a city that are completely walkable within 15 minutes was developed by urban planner, carlos moreno to give paris escalades ecological, economic and social foundation in the future. the 50 means the concept is a new paradigm for living definitely in cities, we wanted to reduce that sure to be shocks. and at the same time, we want to to bring the quality of life for developing intensity in proximity. we want to, to promoter city based on the federal centers, say different places for a leading to reduce the role of individual car deceased. new pass for hiding they sherman at the center of city ecology, proximity. so daddy,

t and the citizen important are default killers. the roof balconies city as parties is very cushion. the role of counties not same factor in the center of cities in the high density zone, sorry for all channels that i voted that can see them. they probably co pay. so ease only for a going with my car, the role of car ease and or this point in particular for going for a 2040 kilometers but not for day. very short term. there are other changes efforts including a make over of the shows the z. we, the architect entrusted with breathing new life into the heart of the capitol. harris is one old european cities and like most cities in the seventy's, it's a city that has been over one was course, and the case of the shows it is a is an interesting example of this problem is very symbolic area in paris, very famous. but he had something incredible that the parisian hate this 2nd. why

is because it's an area that used to be for the past century, a place where you would go for a walk with your children. was a nice moment. it was the most elegant avenue in parish their local people lot and we figure out that since 40 years, no one wants to go there except tourist. the car, of course, is one of the key problem to give this face back to people and pedestrian. because all of this has been treated as a highway entering fabric was 2 times for lanes going up and down and you have pavement varies in south. that is very noisy. so if you go there channels it, is it today's like it's one of the most noisy place in reducing the part of the car and getting this place accessible to people is one 1st action. of course we can complete the band card. so, you know, it's a big debate in paris. the mayor has been planning cause on the sand river is getting a lot of political conflict about that. so i think we have to be careful then being a bit scientific about that unless ideology. so that's very important. we want to

be very methodological certificate fighting the pro or you know, against car. the other aspect of so that we want to introduce is understanding better the way nature in the cities working as an ecosystem. the climate change. we can have a lot of warm spot in paris and this avenue is very hot spot. so i can you use a natural element to cool down the city. but that is a simple conclusion to a more larger and more scientific study. which is to say are kind of we enough tomorrow, the scientific knowledge of reducing our footprint on hers. and that's working on all the cities because that's where 85 percent of the damage are produced on 2 percent of the surface of the planet. changing the city is not something you overnight. this vision we propose start in 2025. it's maybe going to be done in 2035. it might sound like perish is taking the long view, but for a city that counts its age in millennia, 15 to 20 years is

a very short spin of the whale. much depends on whether parisians are ready to support this revolution on their streets. ah, bus alone is overcome early opposition to school some quick wins, but here to the hardest work is still to come. 50 years after starting to reclaim that streets. dutch cities such as amsterdam and hong, and must still work hard to put humans, the head of car. what will other cities do about their autumn, a love affair? while individual vehicles, ciocca st. pedestrian, a bicycle activity will remain, rand. i'm saying. can people living in 21st century mega cities expect politicians to tackle pollution and climate change to make those city for the best time to reclaim our strengths was yesterday. but i think the 2nd best time is today, and it's so important because many challenges that we face as society in terms of

global sustainability. but also local livability can no longer be solved if we do not reclaim our streets as public spaces of places that are there to support, not only the throughput of vehicles, but to support the thriving of our society. we'll leave enough to young. i'm the dangers of green washing our traffic problems away. if you liked this special report, check out d w ref on youtube to see more films like this. a ah, with
