right, cassandra, in 2016 1st. our 3 pa documentary series. i'm asking has paula stats may 4th on dw do you 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 a 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 mega city populations are exploding. according to a un report, indian capital daily will hit 43000000 in the next 10 years, and that's just one example. when cities grow,

the needs of its inhabitants rarely prioritized. so in order to better understand those needs, city 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 built. and that's what we have here, a digital twin of when dpi, a future 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. the next day use the digital twin to map out the general design of the district and to find

a deal spots for schools shops and coffee ice. so the 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 city escaped greenery end with a will affect the mark or 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 uh change the wind on top of it. then suddenly i can see the heat islands and the cold islands changing. 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 quote, reduce c o 2 emissions,

but 80 percent of the 1st 5 years alone produced. and so it helps us to see how much materials we need, 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. hopes that more digital twins will be developed using this software in accordance with 8 cities, you make 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 known as like min by in india for example. so just take the tool, you put your pop in,

and you can actually work with for yourself on 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 gram satellite city of delhi. both of his sons live abroad with their families and only as we do feel lonely. our children wants us to move a brewers, but it's difficult. uh, yeah, and honestly we belong to a generation that loves around 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, they service m o 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 adult uh, looks up to the couples, needs and gives them company to the economies. the caregiver is 25 year old. my name is shawna tmo. 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 medic of history, the doctors and insurance details. maple the officer, lots of people who look quite old and 11 is the children live in a different country. when can somebody take care of a lot 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 worse. currently i take care of 35 people and go with the kids as well. how may i select my email treats us like a family member? i guess she asks about so daily routine to size up and immediately noticed the

final sound in low and off of everything is okay. if the week the gets good. anything. yeah, i've done the opposite of about services like a mo, a come at a cost. the membership plans range from $0.50 to $170.00 euro is per month. in most states that medical records and other information are 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, but bulk of them in nor date find it. i know for the 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. so may 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 leaving a more sustainable like 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 incense buy 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. so 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 low shops. grandson currently has 800 uses in 3 countries. the majority of whom

live in the hon, gary and capital for the past, and in munich in germany. in europe, more than a 1000 great mobility companies work with incentives. but cities need to have a few things in place to use these programs. this could be increasing pedestrian eyes designs 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 says it's gains are 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 you 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 stock and grable. what'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 rates, 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 pleasant and less? how many streets and black roots ensure 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 was able to support informal settlements in the city as many in 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 and these images, and to better understand a society without making a single survey. you know, says who knows what linquist. the research is, trained a data model named newton. this system analyzes data to predict the future was the 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 city. 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 spot. so know this as this of my self funded satellite images also serve as a valuable tool for identifying informal markets trading outside of formal

instructions. this allows experts to monitor the conditions. the merchants can see him as an employees a lot. a lot of them that since they know for the neural network which 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. those 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 lice. plenty of this, the other stuff point is they were being able to use it will be stipend sources of information in open. the software obviously allows us to reach a new level of complexity. we can even increase a little variable currently impossible to test with the official information, but this data can really enhance our research processes. during the day the, this,

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, houston, those who did in this life bringing down, i'm sure that can, would you be you. and also what do you need to come cause is 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. 30 minutes on the w august cove. pushing up inside the ring. a new generation against stereotype presents for the future. in 90 minutes, only d w the

one on 6 times to increase the current g more people than it in the world line in such a better price than mine. and one time it is very, very difficult, john to find out about time on story info. my grands g w, this is the, is available, sam. and it has met up in some sense the

this is date of the news and these are the top stories. a staff member of germany's fall arrivals toner to for germany potty has been arrested on suspicion of espionage. prosecute to say he was spying on behalf of china. the worker was an assistant to maximilian. call the f. d stopped candidates for the european and let fall into elections. the rest came less than a day off the 3 german nationals, but detained on similar charges. several of us universities have close campuses and switch to remote learning, as most students joined protest camp against the board in gauze on hundreds of interest of since last week.
