and that's it from me and it is team. so now the way up next many residents of increasingly crowded city is so far lower than this shift looks at all technology technology can help. if it comes up after a short break, i will have a web is update for you at the top on the i've got office in berlin. thank you very much for watching the conflict. crises was, every single connection mapped out shows the geopolitical reality be on the board is what makes things the way they are mapped out. navigating a changing world now on youtube, driven by greed in the 2000 and start you back engaged in various time risk business practice to each of our includes basically involved in every shady scandal

in the banking sector worldwide. raised for ever higher process. and then the minds of the german institutions, the dodge of back story, stuff may 2nd on d, w. they live in the countryside or in a city, more than half the world's population now lives in cities, and that number is only growing city. life often means of crowded spaces and less traffic jams and bad infrastructure. and when people move to new cities, loneliness can be a huge problem. it could also be an issue for older people. luckily, there are quite a few solutions floating around, and that's what we'll take a look at today on whether it's kinshasa, tokyo or deca, megacity populations exploding. according to a un report, indian capital daily will hit. let's see 3000000 in the next 10 years. and that's

just one example. when cities grow, the needs of its inhabitants really prioritized, so in order to better understand those needs. so the plan is in a stony is capital talent, came up with a new idea. digital twins creating virtual copies of new districts before they actually get billed. and that's what we have here, a digital twin of when we pay a few to district in a stony as capital talent. the virtual representation helps to test and improve living conditions in the new quarter before the building process stops. what are the benefits of having a digital twin and the planning stages is, for example, we can already uh, simulate to mike requirements and look how we change the cityscape to actually make it better for us people. and for nature. marcus hell, and his team created this digital twin with the help of data on the structure of the area transport routes, the weather and vegetation. next they use the digital twin to map out the general

design of the district and to find a deal spots the schools shops and coffee ice. so digital twin firstly helps you place the density to different spots and play around with that. and understanding where the people are in that area. and this is actually the foundation, the digital twin that can also simulate construction materials and energy demand and helps the plan is calculate how the cityscape, greenery and weather will affect the market. the climate of the new district right? change the street 20 degrees to the left. i put some trees on front of the waterfront and now it's changed the wind on top of it. then suddenly i can see the heat islands and the coal, dinah exchanging. and this gives me, for example, this universal thermal comfort index, which measures which temperature are comfortable for people. tell estimates that

using the digital twin quotes, reduce c o 2 emissions, but 80 percent of the 1st 5 years alone of the truth. and so it helps us to see how much materials we need uh, what is to our footprint in general and what happens if we change out those materials instead of having to rely on experience and opinions. digital twins, fed with large amounts of data can find the best possible options from an environmental, social, and economic perspective. this could also help promote using public transportation walkways, bicycle lanes and recreational areas. l hopes that more digital twins will be developed using this software in accordance with each cities unique requirements, the 3 to 55 years. our plan is actually to make it more self service, more universal. so able to actually apply to places that have a much different climate than this don't as like min by in india for example. so

just take the tool, you put your pop in, and you can actually work with it for yourself. and by and tell him clearly a very different cities, but they do have one thing in common. many people living that can often feel lonely . in india, there's an app for older people to combat this problem. it's supposed to help those who feel alone, online and offline, gender content and remish and sunny live alone in a flat include a grammar, satellite city of delhi. both this on live abroad with their families. and the only thing that we do feel only our children wants us to move a brewers, but it's difficult to. yeah. and honestly, we belong to a generation that loves or in indian culture, saying no matter how many facilities are available in other countries, it cannot replace the comfort we feel here. and when the children recommended the up based service and the the helps the overly access medical services,

home health care and maintenance services, and even a community to engage with of entertainment sessions. a caregiver cold amolla daughter looks off to the couple's needs and gives them company. so the sony's, the caregiver is 25 year old. my name is shawna dmo . a daughter spends time with her assign senior citizens and helps them sort out their medical documents by using the app. it lets you add a person's medical history, the doctors and insurance details maple the task for lots of people who are quite old and the children live in a different country. when can somebody take care of and lots of things with the medication. but the medical appointment is off, so for and every day we call them at a particular time to check on them to see if they need anything. or currently i take care of 35 people with the kids as well. how may i select my e mail treats us like a family member?

i guess she asks about so daily routine to size up and immediately notice the final sound in low and off of everything is okay if the week the gets good. thank you. i've done the opposite of but services like i'm a come at a cost. the membership plans range from $0.50 to $170.00 euro is per month. and most states that medical records and other information us safe from misuse. however, great cat should be executed when handing over the information to a company that a good option for those people who can afford it. the bulk of them in nor dates find it unaffordable. societies have found an affordable plan in the mo, the provides them with necessary services, and it's also giving them a dependable companion, like my email from a giving unload, that's human touch is a great idea. another classic problem we see was cities of traffic jams,

in places like london or los angeles, commuters can spend several days a year stuck in traffic. not only are they a waste of time, but they also bad for the environment. so aside from living a more sustainable life, how can we motivate people to switch to public transport or cycling? perhaps by creating a reward system. let's talk about transportation. going places without a car could help save c o 2 emissions. and it might even get you a discount, green mobility companies that helping individuals to reduce the own emissions related to the transport by helping incentivize them and reward them for using low carbon travel. for example, green said that using that technology to reward people for cycling more into what the grain sent up trucks, the distance uses travel on that box on public transport luck buses. all the subway for every 6 kilometers traveled without a car uses awarded one green sense. these natural tokens can then be used in local

shops. grandson currently has 800 uses in 3 countries. the majority of whom live in the hon, gary and capital, pull the pests and in munich in germany. in europe, more than a 1000 green mobility companies work with incentives. but cities need to have a few things in place to use these programs. this could be increasing pedestrian ice zones, developing most likening lanes and just always improving public transport to ensure that as many people are kind of sharing out these emissions rather than using their own cause and such as change the only one piece of the puzzle to reduce traffic and emissions to improve the quality of life in cities. but research has shown that these loyalty programs can motivate users to reduce that carbon footprint. often people do need that extra push to start engaging with climate solutions. you just

download an app and then it kind of tracks it for you. so there's a limit to what you need to do to start getting verbal. it's the living a low cost and lifestyle in order to increase the quality of life in cities. plan is the data, the getting thought her own cities is easier said than done because they're constantly changing. and in some countries, you'll find that not all houses and markets even registered rate, such as a full the peak above and project in columbia. and now using satellite images for their analysis, how much water does the city really need to keep its residents healthy and happy? and how many parks are essential for a pleasant oven? less how many streets and black roots in short, good traffic flow of cities and demands change. informal settlements on planned and unauthorized housing areas can lead to limited access to infrastructure and basic services at the university of faith. in many, in columbia researches in the peak of and program of discovering the power of

satellite images. by analyzing these images, one carlos to k and his team were able to spot informal settlements in the city as many. and the images also allowed them to spot impoverished areas know, sources that are done this. we develop quantitative methods. this allow us to generate variables from these images. and to back to understand a society without making a single survey. you know, says who knows what linquist the research is trying to a data model named newton. this system analyzes data to predict the future will also requirements in a city based on oven growth projections. was there for them. i've got some stuff. you download a series of historical photographs of the seats and you want to analyze for free, artificial intelligence, specifically neural networks and begin to understand the dynamics that grows and can then make full costs for the future if those happen spots. so not a whole sort of this of this of myself. satellite images also serve as

a valuable tool for identifying informal markets trading outside of formal instructions. this allows experts to monitor conditions for merchants can see him as an employee's, a lot, a lot of and that since they know quite often you're on network res trades to detect more scientifically marshal presidents, eckleman like a storefront, this couple matching dice on display and cx he said, we looked at millions of points over the city to process them with this tool, and then had new maps of a distribution of commercial activity within the city. that you will see on the outcome of 7 plus the use of satellite images has also become crucial for the global challenge of sustainable and mobility life pointing. and yeah, that's the best point of the point of being able to use it will be stipend sources of information in open. the software obviously allows us to reach new levels of complexity. we can even increase your variable currently impossible to test with the official information. but this data can really enhance our research processes

during the day and they use the analyzing satellite images can be very useful in of, in planning to safe god sensitive information. however, data security is crucial when using them. and there are many examples of how tech solutions can help improve the quality of life in cities. but in order for these solutions to really have an impact and make a difference, authorities need to fully embrace and promote them. what changes would you like to say in your city and do you think technology can help find those solutions? get in touch with us on social media and let us know your ideas. that's it from us today. so you, next on the we travel across the african continent to houston,

those who did in this life bringing down, i'm sure that can motivate you. and also what do you need to come to the peers and other come challenges. young people in africa know all about it. they're ready to stand up with a ride to fulfilling self determines like the 77 percent on the w. the new will tell you. happy that way of boxing. the story we have a getting a visa is more difficult than finding gold hosted to use force and for the future in the stories and issues that are being discussed across the country. news africa. in 60 minutes on d. w. jasmine with 12
