1st group to put a. lot of us and israel. into. the degree of work. if you live in the country sights surely familiar with the smell of fresh air the sight of a clear blue sky and the feel of y. 80 in space it's simply gorgeous and that may make you wonder why anyone would choose to move to a city of the fact is 3 quarters of the world's population now live in towns and
8:31 am
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 urban 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 are needed and sooner rather than later. mushrooming megacities are a global phenomenon 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.
8:32 am
that cities are microcosms of society can observe all the opportunities and challenges in a very small space like under a looking glass and glass. 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 paolo 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 at an office or.
8:33 am
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 prominent reserved for pedestrians only. welcome to the 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 many 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 but 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
8:34 am
by 80 percent. been going to the smart sharing system people could still enjoy the same level of mobility mentioned. meanwhile at the other end of asia in saudi arabia there are plans for a new megalopolis knee arm 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
8:35 am
kinds of jobs and economic development in saudi arabia. the country is seeking alternatives to it's based economy me on 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. grids energy will then also be used for desalination . because water is a big problem here. is an acronym for the 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 into 2 projects have something in common it's that they are not
8:36 am
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 i plan on. open 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. well all i know is that compared to cities like tokyo or mexico city but lynn is a village and it does have lots of parks and green spaces like tree lined all of us but the streets are getting busier traffic is getting worse it's not just cars 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
8:37 am
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. overseeing gets around by bike. 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 don't have to shout at one another over the roar of porches was it i asked a porter. the platform fix my palin was set up a year ago for the city cycling community its allows users to see for example where there's a new cycle past or where
8:38 am
a new one is planned it already has over 1500 users the idea is to put pressure on them planning authority if. 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 be reduced. 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
8:39 am
a street you'd think would be quite dangerous for cyclists. we look at their trajectory see if they often need to overtake trucks and buses say and see if that could be quite high risk of competency out of. their findings could be used by urban planners to redesign busy crossroads for example. traffic patterns are constantly in flux recent months have seen a 25 percent rise in cyclists on poland streets. when the pandemic hit the city created a number of pop up cycle paths. but the fix my palin team says those still a lot of work to be done. 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. for chefs are. not
8:40 am
yet at the visionaries of city law are working hard to get to speed. green with pop up a bicycle path going in the right direction for the future of mobility will still include costs and while many consider any cars oil electric cars a sustainable alternative to gasoline and diesel power 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 e-cards use raw materials mined in south america the democratic republic of congo and china these include lithium cobalt and rare earths needed in our
8:41 am
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
8:42 am
and often way less finding a tracking 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 maybe about to dawn. so whether electric gas or diesel far too often cars end up stuck in traffic jams but why because 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 unts
8:43 am
and when it comes to regulating traffic they seem to have it figured out there are no jobs on their motorways. bad traffic bad guys. anti ways 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. 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 sao paolo gridlocked 340 kilometers of
8:44 am
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 they did not pay him enough attention and then they have to brake hard. works and then there's heavy weather condition it's very close to 60 percent 70 percent into the.

region there is. still a grass in this inquiry into syria. as soon. as there's no orders to get it if you're going to get over it. but the ant world runs differently. than our businesses he has without 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 ants. in order office when the time for action on. the driver's road. to. wisting. there is a thing which hinders the whole system to be effective. just

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 bengal in $29.00 drivers in the indian mega city spent an average of 243 hours stuck in traffic. but want to come. world beating congestion look no further than mine know that researchers worked out that in 2019 route users in the capital of the philippines last 257 hours of their lives to the commute too 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. communicate via sense they have plans to produce them various pheromones convey information such as danger food or this way. i think it's long work for the community they want their system up to and that once. working or throw it sure is not stopped by individuals because. i don't think that one can teach people to. answer depends on a communal effort and adapt 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 theirs even if it were a speedo so they just take you to notice. highway if you say they

there they are people. working a traffic system which has a much larger capacity that's me if the. insights romance might soon be translated into better traffic grabbing entertainer. 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 than speed and slam on the brakes. perhaps then we'll be able to see of ourselves a lot more time and money and the void scenes like this. ready ready and how do we get one h.r. into a city pops 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 equal friendly and healthy now ancestors lived in what nots perhaps it's time for this material to experience and

run a sense. it's a report with dean in 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 that is a connection after all. that might explain why would the fashionable construction material. it's those almost 20 percent of new build 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. 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 bed. cities decided that the entire district should be built of wood 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's 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 of a source of 38 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 the 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 robbie has been working with wood for well over a decade. definitely pioneers and such we've also suffered we had to overcome many obstacles met with a lot of resistance from the north or a g.'s we had to assemble a team of experts and of course convince our clients property owners to begin with

it was anything but easy i thought. biden 48 in berlin is a recent project of his 6 storey color up with about 40 apartments is almost entirely made of wood and a finalist for the 2021 german sustainability on board for architecture. to be honest our practice didn't originally warm 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 wonderful high rise it's 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
8:55 am
in a neighborhood in a community if you live in a project like this you. to have the right attitude toward as well because it lives and moves in creeks. you have to be able to and want to deal with that. 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 felled trees selectively importing timber from further afield would be less sustainable. construction has its downside at the brotherhood site in downtown berlin but if all goes to plan the wooden skyscrapers should be standing by 2026. and that was the final urban vision for. this edition of made. for me in the team
