one year old instead of going to class and doing can attend classes only to be finished. millions of children all over the world go to school. we know school hard. because of education makes the world more just. make up your own mind. w. me for mines. if you live in the country sights yes surely familiar with the smell of fresh air the sight of a cli of blue sky and the feel of why 80 in space it's simply gorgeous

and that may make you wonder why anyone would choose to move to a city but the fact is free quarters of the world's population now live in towns and cities that is over 5000000000 people and as these areas grows so do the problems from traffic congestion to soaring energy demands what we need. visions our topic today are made to welcome now did you know that one in 8 people not only live in a city but in a mega city sharing limited space with millions of other inhabitants and now imagine those millions on their way to work not sure if the term rush hour still applies in order to ensure people can actually move from one part of a city to another new mobility concepts a need it and sooner rather than later. mushrooming megacities are

a global phenomena there are now 3 times as many urban areas with $10000000.00 plus residents as just a few decades ago. but as cities grow so do their problems. and cities are microcosms of society we can observe all the opportunities and challenges in a very small space like under a looking glass and glass the income. the biggest conurbation on the planet is greater tokyo population 38000000 followed by jakarta with around 34000000 delhi mumbai manila and shanghai each home to more than 20000000 people as are the biggest metropolises in latin america sao paulo and mexico city. traffic is a major problem in megacities but there are new ideas out there on how to tackle it . we're also used to cars that we can't imagine cities without them anymore but

if we were to experience that we wouldn't want to go back to cars in office or call and. this is how cities might look in future if different kinds of road users were separated one road is for fast moving electric vehicles another for pedestrians cyclists and scooters with the 3rd a promise not reserved for pedestrians only. welcome to woven city a project under development by japanese carmaker toyota a prototype city and living laboratory for cutting edge technologies. here all vehicles will be self driving and run on electric power or hydrogen the mini city itself will be powered by solar and geothermal energy with everything coordinated centrally by ai technology. it's been designed for a part. relation of 2000. people he kluger that we need it smarter ideas about how

people can move around. in a city with 5000000 residents and 3000000 cars that are idle 90 percent of the time you just need to do the math. so that you could probably reduce the number of cars by 80 percent. or they're going to have a smart sharing system people could still enjoy the same level of mobility and sort of mention. meanwhile that the other end of asia in saudi arabia there are plans for a new megalopolis neon a linear city comprising for. the pet project of the saudi crown prince is said to cost an estimated 500000000000 euros road and high speed rail transportation are all electric and underground. nicknamed the lie because it's meant to be 170 kilometers in length is designed to be carbon neutral with a 5 g. network driving all manner of applications.

right now it's a thinly populated and undeveloped area. we want to create sustainable infrastructures and stimulate economic activity. which will in turn create new kinds of jobs and economic development in saudi arabia. the country is seeking alternatives to its based economy me elmo should also boost tourism and attract startups and media production companies the entire city's energy requirements are to be supplied from renewable sources. have a huge amount of sunlight and ideal wind conditions so our energy system will run exclusively on primary energy. and this energy will then also be used for desalination. because water is a big problem here. it is an acronym for a new future the plan is to create

a city for 1000000 people in just 10 years but is that really feasible. let's combine them if the 2 projects have something in common it's that they're not what was originally hoped for blueprints and reality are miles apart the projects assume a managerial perspective which ignores the fact that cities are more than just infrastructure what draws people to living there is not something you can plan just like not plan. well one city and me arm 2 visions of eco friendly high tech cities where people can actually enjoy life but will they actually get off the ground. all i know is that compared to cities like tokyo or mexico city but then is a village and it does have lots of parks and green spaces like tree lights all of us other streets are getting busier traffic is getting worse it's not just cos

delivery vans and buses and of course more and more people are riding bicycles and there's often not enough room for everyone thinks must change and that's why city planners are joining forces with start ups to come up with new and sustainable concepts. who owns the city streets of berlin are increasingly busy with cars cyclists. get surrounded by spike. lee for nuthin i know. and i don't want to live in a noisy polluted concrete jungle but i want to live in a city where people chat on the pavements and comment don't have to shout at one another over the roar of porches was a gas deporter. the

platform fix my palin was set up a year ago for the city cycling community it allows users to see for example where there's a new cycle past or where a new one is planned it already has over 1500 users the idea is to put pressure on them planning office or it's. hard to measure already said planning a new bicycle boulevard or new bike racks the public can say whether they approve of the plans. so you can see what's possible what the public sees as a priority and what it sees as less urgent where there is less demand. balance population increases by about 20000 a year according to forecasts the city will be home to some 4000000 people by 2030 . how can traffic in the jeeps. how can traffic flow be diverted to reduce congestion and pollution these are questions that a group of scientists are seeking to answer with the help of data collected by

traffic cameras. in the let's. let's take a busy berlin street as an example a street you'd think would be quite dangerous for cyclists. i would look at that you check terry's see if they often need to overtake trucks and buses say and see if that could be quite high risk of plan put in. their findings could be used by urban planners to redesign busy cross roads for example. traffic patterns are constantly in flux recent months have seen a 25 percent rise in cyclists on poland's streets. when the pandemic hit the city created a number of pop up cycle paths. but the fix my team says those still a lot of work to be done. i mean not.

compared to other cities the mayor and the city government aren't very invested in cycling policy. in paris and london it's a political priority. of soccer crowd. not yet but the visionaries at city law a working hard to get up to speed. the green with pop up a bicycle past is going in the right direction but the future of mobility will still include costs and while many consider any cars oil lek trick cars a sustainable alternative to gasoline and diesel powered transportation it's not that straightforward is a look at some of the issues. electric cars like me are still quite a rare sight there is only 11 and a half 1000000 of us worldwide that's just a tiny fraction of the estimated $1400000000.00 cars in total but our numbers are

growing economists use raw materials mined in south america the democratic republic of congo and china these include lithium cobalt and rare earths needed in our batteries it medically extracting and transporting these materials is an environmental nightmare often carried out under inhumane conditions. their reserves are abundant studies show that worldwide deposits of these materials could meet demand for years to come one good thing about us e-cards is that we don't emit greenhouse gases although manufacturing certainly does all my components still have to be produced but my power train only has $200.00 parts as opposed to a combustion engines $1400.00 where my electricity comes from is another huge issue renewable sources or fossil fuels the good news is that the share of green energy

is growing which definitely plays in my favor as battery technology improves the range of e-commerce is increasing. right now it's rarely more than 500 kilometers and often way less finding a checking station can also be an issue. as to our batteries 95 percent of them could be recycled in an environmentally friendly way but it's still not economically viable. but i recommend you sit back and relax it's surely only a matter of time today electric cars cost more than conventional models but that gap is closing the day of climate friendly affordable electric cars may be about to dawn. so whether electric gas or diesel far too often cars end up stuck in traffic jams that's why because health

there are simply too many cars on the roads but we can look to mother nature to find a perfect example of how to keep traffic running smoothly and i'm talking about. when it comes to regulating traffic they seem to have it to figured out there are no jobs on their motorways. bad traffic bad dives. and highways are also super busy but clearly run a lot more smoothly. in the human world congestion on the roads is a normal part of life we even keep track of record breaking jams. when hurricane rita hits the southern united states in september 2005. 2 and a half 1000000 people fled houston or tried to the resulting tailback on interstate $45.00 heading inland towards dallas reached

a length of 160 kilometers for 48 hours. in the run up to the 2014 world cup in brazil the roads in and around sell paolo gridlocked 340 kilometers of stationary traffic almost equivalent to the distance from sao paulo to rio moscow november 2012 the notorious russian winter paralyzed much of the biggest country on the planet for 3 days and 3 nights snowstorms plus the highway between st petersburg and the capital. but how do traffic jams actually come about. the main reason is that you do not have enough capacity. of course. these reasons reasons are not that they do not happen that often. dumb people sometimes make driving mistakes of course for instance a bit not paying enough attention and then they have to break our. words

then students there's a very weather condition it's. still there 60 percent or 70 percent due to there is in this region or. it is due. to the grass in the center of the syrian. there's no orders to get it if you're going to get over it. but the ant world runs differently. when i'm as a salesman than to the principle is one for all and all for one hardly applies to motorists on the road everyone's thinking what's the quickest way of getting to my destination individuals focus on themselves and don't care about the others. drivers have a lot to learn from hands. off when the time for action i'm. at a driver is going to grow their own corporate or serve their wish to parents

there is a thing which here in yours always 1st series treme deceptive spirit is just a mere difference or for the very good it's. not seen that it is if you know if it uses doing and a system of doing they're wrong and if they're the ones where for concern with this situation so that it is user to me but it's not for the system to display so and cooperate and have a common goal humans on the road due to no way they each want to get from any to speak but the lack of cooperation results in countless people wasting vast amounts of time in traffic jams how much time precisely. telemetry experts have the figures take for example germany's biggest city think pompom has made this kind of

statistics and they have a number of days home much more time have you invest on your daily commute to and from the world and this number is about 30 percent in other cities it's much much worse. 3rd spot goes to bogota residents of the colombian capital spend an average of 230 hours a year going nowhere fast that's almost 10 full days the frustration can sometimes boil over. number 2. and $29.00 drivers in the indian mega city spent an average of 243 hours stuck in traffic. but when it comes to world peace interim gesture look no further than men know that researchers worked out that in 2019 road users in the capital of the philippines last 257 hours of

their lives to the daily commute to many self-absorbed drivers with big egos crammed into narrow spaces. anti waste by contrast are always busy but never congested how do they manage that. sense to communicate via sense they have to lands to produce them various pheromones convey information such as danger food all this way and think it's long there the minute you do not there the system up there and that once you're. looking. through it should not stop by individuals because. it adds to think that you can teach people. and still tend on a communal effort. and as daft as conditions change humans communicate not so much with each other as against each other and while costing us precious time that comes

at a financial cost as well. as surgery and if it were a speedo that didn't take you to notice. highway if you say a kid on later today for 3 hours then if you got only 10 instead of 80 then you're going to convert what is the last time for the guard there to. it being 51000 and you know. it and i calculated. or germany for example. you have come up with say 60 to 100000000 you were all year. 80000000000 euro. just by standing still in chips so you don't only it was tired. so what people

can learn from else. and if you're going to put a medic sisters can copy the behavior of. this is the hope that then at the end will a good king and traffic system which has much pest. if they're doing. insights romance might soon be translated into better traffic routing better attitude it's ultimately up to us we need less ego and more consideration for others it's better to cruise at a moderate speed for example then speed and slam on the brakes. perhaps then we'll be able to see by ourselves a lot more time and money and up void scenes like this. ready. and how do we get more nature into a city pox help without a doubt but what about those places we actually spend most of our time in buildings

from offices to homes shouldn't they to be more eco friendly and healthy now on systems lift in wooden huts perhaps it's time for this material to experience a renee sense. stands for report with demon a forest. cares that they have nothing to do with the story. the story is about construction sites concrete buildings and the hopes and dreams of people living in concrete buildings. maybe it's forests full of did they dream of there is a connection after all. that might explain why would the fashionable construction material. it's those almost 20 percent of new builds in germany made of wood. just about anybody who enters a home made of wood is almost all was overwhelmed by its quality and that most fear

. if you go into a newly built would announce you'll feel wonderful from the very 1st moment thanks to the structural design and the very special atmosphere. thomas this company is developing what is said to be the tallest wooden apartment building in germany 29 stories 90. 1 have to go up in building. cities decided that entire district should be built of wood new school buildings made of timber and there is some justification for that we have to aim to be climate neutral in our city's trees of brown c o 2 for centuries and when the timber is used for building it remains bound. that the key difference between wood and concrete. concrete is

getting a lot of bad press nowadays a key ingredient is cement and according to the un's intergovernmental panel on climate change the cement industry accounted for 3 times more c o 2 emissions than commercial. every haitian in 2019. another u.n. report says construction and building usage other source of that 8 percent of global c o 2 emissions. concrete is the default construction material at least for large scale projects and entire new concrete courses going up in a district of. only one building currently under construction will be mostly made of wood only its foundations and staircases will be made of concrete architect or robbie has been working with wood for well over a decade. definitely 'd definitely pioneers and such we've also suffered

we had to overcome many obstacles met with a lot of resistance from the author of these we had to assemble a team of experts and of course convince our clients property owners to begin with it was anything but easy. but in 48 in berlin as a recent project of his 6 storey up with about 40 apartments is almost entirely made of wood and a finalist with a 2021 german sustainability on board for architecture. to be honest our practice didn't originally want to wood for ecological reasons it was 2007 i started thinking about wood perhaps 2 years earlier for it's a static aspects. beautiful it was only later that i learned how to eco friendly it is and that it binds large amounts of c o 2. out of. the one of the high rise is not just meant to be eco friendly but also an exercise in inclusive and social cohesion it won't be condos

for the rich but rather housing for people of all income levels. it's about living in a neighborhood in a community if you live in a project like this you have to have the right attitude toward his world because it lives and moves and creeks. you have to be able to and want to deal with that void . but to build with timber you have to cut down trees how eco friendly is that. we certainly shouldn't just chop down entire forest so they're gone forever we need to use the resources we have in germany and central europe and shell trees selectively importing timber from further afield would be less sustainable. construction get started at the other home site in downtown berlin but if all goes to plan it wouldn't skyscrapers should be standing by $22.00.

and that was the final urban vision for. this edition of made. for me in the team here in berlin thanks for watching.
