i said to mike, more than the minds of the german institution, the george of back story may 2nd w. 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 a 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 contrast that tokyo or deca mega city populations are exploding according to a you and 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 depot 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 the micro climates 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, then to find

a deal spots the 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 and weather will affect the market climate of the new district. right. change the street 20 degrees to the left. i put some trees on the front of the waterfront and now it's uh change the wind on top of it. then southern the i can see the heat islands and the cold dyna 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 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. a pell hopes that more digital twins will be developed using this software in accordance with h city's 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 known as like going by in india for example. so just take the tool, you put your pump in,

and you can actually work with you to put 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, community and as we do feel only our children wants us to move a brewers. but it's difficult. uh, yeah. and honestly, we belong to a generation that loves or in indian culture, 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 for maintenance services and even a community to engage with of entertainment sessions. a caregiver

cold and low a daughter looks off to the couples, needs and gives them company to the economies. the caregiver is 25 year old. my name is shawna tmo, a daughter that 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. the maple the task are lots of people who are quite old and of 11, is that children live in a different country. so you take care of a lot of things and with the medication. but the medical appointment, dr. fuller and every day we call them at a particular time to check on them to see if they need anything. currently i take care of 35 people 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 got anything . yeah, i've done the opposite of but services like a mo, 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. but bulk of them in nor dates. 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, from a giving 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. not only are they a waste of time, but they 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 the own emissions related to the transport by how things incentivize them and reward them for using low common 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 local shops. grandson currently has 800 uses in 3 countries. the majority of whom

live in the hon, gary and capital pool, the pest, 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 lightning 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. instead of stains 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. 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. what's the living? a little 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're 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 folder analysis. how much water does the city really need to keep its residents healthy and happy? and how many hawks are essential for a pleasant oven? less how many streets and black roots ensure good traffic flow? a 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 back to 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 got to be, 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 spot. so know this of this, of my self funded satellite images also serve as a valuable tool for identifying informal markets trading outside of full

instructions. this allows experts to monitor the conditions. the merchants can see him as an employees a lot without removing that, since they know the neural network was traced to tech. to most scientists, commercial president settlements like a storefront in this couple months and dice on display and cx. he said we looked at millions of points, 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 deck comments 7 for lots of yeah. the use of satellite images has also become crucial for the global challenge of sustainable and mobility lice. plenty of this, the best point is the point of being able to use it will be stipends sources of information in open. the software obviously allows us to reach a new level of complexity. we can even explore variable attorney, impossible to test with the official information, but this data can really enhance our research processes. during the day, the c us analyzing satellite images can be very useful in,

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 measures to from what did you do to i'd say the tenant she

survived our streets. thanks to music. he was the nazis favorite conductor, is more on the the genuine to musicians under the swastika, a documentary about this sounds of power, inspiring story about survival of the home. i go get the tennis. i was the only one who lives in nazi germany. watch now on youtube dw documentary, several dead and wide awake. it's 3. miss simmons writes regression began to be in trouble rate and burned in south africa. people with disabilities more likely to release the job of the lack lives matter, protest, shine a spotlight on racially motivated police by the same sex marriage has been legalized discrimination. and we also because like,

instead of the of violence, unrest and strikes, indian administered kashmir has a volatile history, but a new poison has taken over the region and its consuming entire families don't. and that's how you doing. my god. heroine would keep me away from the protests. maryland helped me to run away from them who would want her to treat housing says inches at being used daily like us meeting drug addiction has reached epidemic proportions here. and it's most of the young people in its hold the

every morning ro, honda jump, being an outraged campaigner with a government supported agency in the capital shooting ago, distributes pamphlets in public spaces to raise awareness of drug abuse. what type of drug use is they spend on drugs, entire families or ruins because the money is wasted on drugs. children are suffering. addicts are unable to pay school fees. women are suffering, having health issues for me. when you speak to women living with drug addicts, they are victims of domestic violence. we see bruises on the face as hands and even button motors. i'm ok. it's a challenging job. i have face dangerous drug addicts once or twice. once an outage, even run off to me when we enter the locality, think about some other people.
