as for now, don't go away. up next, residential ethics recently crowded cities suffer from loneliness. shift looks of how technology kind of help here. that's after source slow phone use. of course, on our website, that's d, w dot com and, and all social media channels. i've got office thanks for the words people have to say yes to the that's why we listen. because every weekend on d w, it's time for vision raised for sustainability. but also for horsepower

the, it's time for the mobile revolution. on the 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 of crowded spaces and less traffic jams and bad infrastructure. and when people move to new cities, loneliness, it 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 deli, we'll hit,

we'll 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 talon 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 one of the p, 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 starts. one of the benefits of having a digital twin and the planning stages is for example, we can already see relate to mike requirements and look how we change the cityscape to actually make it better for us people. and for nature mock as 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 fund a deal spots the schools shops and cafes. 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 stimulate construction materials and energy demand and helps the plan is calculate how the city escape greenery and weather will affect the mark or climate of the new district. or i change the street 20 degrees to the left. i put some trees on front of the waterfront and now it's a change the wind on top of it. then suddenly i can see the heat diamonds and the coal dyna exchanging. and this gives me, for example, this universal thermal uh, comfort index, which measures which temperature are comfortable for people. tell estimates that

using the digital twin codes, reduce c o 2 emissions, but 80 percent of the 1st 5 years alone are produced. and so it helps us to see how much materials we need uh, what is their 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 going by in india for example. so

just take the tool, you put your pop in, and you can actually work way to put yourself on by and tell them clearly 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. don't mean as we do feel, only our children wants us to move a brewers, but it's difficult. that's a good. 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, they 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 that spends time with her son, 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 are lots of people who are quite old and the children live in a different country. so you take care of and lots of things with the medication, but the medical appointment is also 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 noticed the final sound in low and off of everything is ok if the week the gets good. thank you . i've done the opposite of but services, lock and loa 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. but bulk of them in nor dates, i find that an affordable societies has found an affordable ton in the mo, the provides them with necessary services. and it's also giving them a dependable companion, like my email from a given unload that schuman 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. it's not only all day a waste of time, but that also bad for the environment. so aside from leaving 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 their own emissions related to the transport by helping incentivize them and reward them for using low carbon travel. for example, green cents 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 be used in local shops

. great cent 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, i'd 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 says it's gains are only one piece of the puzzle to reduce traffic and emissions to improve the quality of life in city. but research has shown that these loyalty programs can motivate users to reduce that carbon footprint. helping 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 start getting verbal. what's the living? a low common 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 constantly changing. and in some countries, you'll find that not all houses and markets even registered race, 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 plant 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 support 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 and the images into it back to understand a society without making a single survey. you know, says who knows what linquist, the researches 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 got some stuff. you download a series of historical photographs of the city you want to analyze for free and artificial intelligence. specifically, neural networks and begin to understand the dynamics that grows and can then make full costs for the future if that does happen, spots so know this as this of myself. satellite images also serve as

a valuable tool for identifying informal markets trading outside of full instructions. this allows experts to monitor the conditions. dimensions can see him as an employee's, a lot less. since they know part of the neural network was traced to tech. to most scientists, commercial president settlements like a storefront this couple much and dice on display and cx. he said we looked at with millions of one point server, the sitting processions and with this tool. and then had new maps of a distribution of commercial activity within the city. you will see on the comma 7 for less. yeah. the use of satellite images has also become crucial for the global challenge of sustainable the mobility device when you and yeah, the other stuff pointed they were being able to use it will be stipends 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 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? got in touch with us on social media and let us know your ideas. that's it from us today. so you next on the entered the conflict zone with tim sebastian. as the warning ukraine grind on the

neighboring voltage states watch anxiously from the ringside seats, pressing the west to increase a key, and make sure russia dozens with my guest this week is the last to be as 5 minutes to kristy on this current. and he's clear nature as to optics can come fix the next on d, w the secrets of the world as no co noise. what is the role in the cops health system? most of age, send them to their integrity in this line of work. they serve the organized crime, a rag livingston to the legal chambers of mexico's cl 15 pills in 30 minutes on the w. thoughts.

we say there about never getting up every weekend on d w, the the as the boring ukraine grinds on, the neighboring voltage states, what's anxiously from the ring side seat, pressing the west to increase a to kia and make sure russia doesn't. with my guess this week is the last to be as 5 minutes to 50 on these kinds. and he's clear nato as the up. it's good. the difficulty in the frustration that i feel is that as we are going step by step, russia is going full frontal forward. so how ready is nato to take on an expansion is russia. why are some rich european states phil? i'm willing to meet the alliances defense spending targets and was present the

macro really calling his allies.
