In a world rapidly pivoting towards urban living, cities are brimming with complex challenges like housing shortages and traffic jams. Despite these hurdles, there's a silver lining: technology. Cities like Seoul are exploiting data to rethink how urban infrastructures run. The heart of Seoul's city management, for instance, lies in how the city has digitized its Metro system, making public transport more efficient and less congested for millions.
Meanwhile, in Nairobi, tech entrepreneurs are rewriting the rulebook on emergency medical responses. Using real-time data, a local startup has developed an app that acts like Uber for ambulances, ensuring timely aid for those in need. It's a pioneering shift in how cities can use available resources more smartly and effectively, sidestepping the traditional roadblocks that often burden city services.
Across the Atlantic, Boston's synergy of academic prowess and innovative thought at MIT is heralding a new era of urban planning. By exploring unorthodox data sources—like robot-collected sewer data—MIT is laying the groundwork for predictive health management in cities. These efforts exemplify how combining cutting-edge technology with human initiative can pave the way for futuristic urban environments.
Transforming cities with technology Transcription
00:00 - 00:30 by 2050 two-thirds of the world's population will live in cities [Music] urbanization that is happening faster than at any time in human history [Music] I think that the problem in cities as they grow is only going to become worse globally 900 million people are living in slums cities can't add housing fast enough today an estimated 1 billion
00:30 - 01:00 vehicles are already bringing urban areas to a standstill cities consumed three-quarters of the world's energy each year and are responsible for around 50% of greenhouse gas emissions these are challenges our cities have been facing for decades but now some city leaders businesses and even citizens are taking new approaches
01:00 - 01:30 to tackling these old problems this is where technology and imagination meet together and we create new cities they're transforming their cities with technology so South Korea one of the most connected
01:30 - 02:00 digitized cities in the world home to 10 million people this city has a population density twice that of New York in Seoul the use of data is seen as the key to tackling some of the big challenges of city life like moving its people around city workers here use sophisticated technology to understand

08:00 - 08:30 and services from the world's biggest technology firms to innovative new startups working from someone's front room this is the headquarters of flair a startup based in Kenya it's young entrepreneurs are working with real time data sourced from that most ubiquitous of modern innovations smartphone [Music]
08:30 - 09:00 Kenya's capital Nairobi is emerging as a vibrant tech hub it is also one of the fastest-growing cities in the world home to 4.2 million people it's more than doubled its population in the last 20 years as in many cities in developing countries the aging inadequate infrastructure is struggling to cope kaitland all cart is one of a new
09:00 - 09:30 generation of business leaders trying to fill some of the gaps the problem in cities as they grow is only going to become worse when you don't actually have the systems in place to actually coordinate and figure out how to do that and like I think that the emergencies are the best example of that because literally every second and minute counts it's 10:00 a.m. in central Nairobi paramedic Nick Makua has been
09:30 - 10:00 dispatched to an emergency call but for many in trouble in the city and ambulance isn't always the answer but if you use the Madrid we'll give you the problem isn't a shortage of ambulances Nairobi has 150 of them double the
10:00 - 10:30 number needed in an average city but the city has no centralized emergency service to coordinate them residents here are faced with 50 different numbers to call for help and no guarantee when or whether their ambulance will arrive Nairobi is doesn't lack resources there's plenty of ambulances and there's plenty of hospitals what there isn't is information - how do you get access to that starting with tools that we have today but from that we're building a
10:30 - 11:00 system that no one's ever had before so you can think about it like uber in the sense that you touch a button and you know the rest is figured out for you you just know that the vehicle is coming your way the app aims to do the job of a centralized emergency service compiling real-time data to coordinate and connect patients in need available ambulances and the right hospitals or healthcare providers
11:00 - 11:30 Nick and his colleagues reach the patient 12 minutes after receiving the call pretty fast for Nairobi where an ambulance can take up to two hours to arrive next team soon discovers the
11:30 - 12:00 reason for the call a gangrenous toe excruciating ly painful but not life-threatening had this man suffered a stroke or heart attack this smartphone based system could have helped save his life across the developing world innovators are increasingly exploiting existing technology to help citizens cope with their city's overstretched
12:00 - 12:30 infrastructure in America innovators are also looking ahead to the next wave anticipating data driven technologies that could help predict problems before they even happen Boston Massachusetts is the 10th largest metropolitan area in America it's home to 4.8 million residents and while Boston may be one of the oldest urban
12:30 - 13:00 settlements in this country it's fast developing world leading technology that could help shape the cities of the future this is the mission of MIT sensible city lab to anticipate the impact of technology on urban life and use it to transform the way cities are run here at mighty we are not in the urban solutions business we are in the urban
13:00 - 13:30 imagination business and this is where technology and imagination meet together and we create new cities lead researcher Fabio Duarte believes that data-driven technology will change our whole approach to urban planning when I start collecting data from nature from infrastructure from people and putting this data together then we can see new
13:30 - 14:00 things about the city that we're not able to see it's a mission that takes Fabio's team to some unlikely parts of the city as I assume that there is thorough search there is collecting data from a sewer isn't a challenge these researchers relish so they've brought along a friend meet Luigi this is Luigi as a whole entire robot this is the brain of Luigi telling
14:00 - 14:30 it how to function Luigi is a probe built with a big job in mind we're able to use store samples and their urine samples in a sewage to understand people's health patterns and health behaviors more at the source this is no crapshoot the samples Luigi is collecting could help reveal new ways to manage a public health crisis
14:30 - 15:00 from prescription painkillers to heroin America is in the grip of an opioid crisis across the country nearly two and a half million people are hooked on opioids nationwide these drugs are responsible for more deaths every day than gun crime or road traffic accidents in Massachusetts between 2014 and 2016 opioid deaths rose by an estimated 50
15:00 - 15:30 percent data alone won't stop this opioid epidemic but data could start to provide city authorities with the tools to build better public health plans that's what the researchers at MIT are hoping in the lab they're learning how to get data from Puu we have the sample that we extracted from the sewage and what we're
15:30 - 16:00 gonna do is we're gonna take it and what we want to extract from it is to separate out the microbes from it the bacteria and the viruses and the DNA so that we can process it for DNA data and we also want to extract the chemicals from it so that we have data on chemical excreted from humans using these techniques the researchers can learn when and where there's been a surge in opioid use or bad batches of heroin but
16:00 - 16:30 they could also be deployed to take control of a host of fast-moving health crises the question is now what are you looking for in that information from this sewage that will allow us to see information on for example if we have viruses that are kind of becoming more prevalent with regards to an epidemic or maybe not even an epidemic just basically an outbreak let's say like influenza in an area
16:30 - 17:00 as researchers of MIT continued efforts to shape the city of the future they're constantly looking for new ways to reveal more about the city of today that's where we change cities when we put different data from different sources together which is why the team has started talking rubbish [Music]
17:00 - 17:30 Boston's garbage trucks travel the same streets every week making them the perfect vehicles for the collection of constantly changing environmental data this one's been equipped with temperature sensors humidity sensors and thermal imaging cameras the key check on the energy efficiency of Boston's buildings and the quality of the city air although we do with technology and we create technology here at a daily
17:30 - 18:00 basis we know that people are at the core of the cities at the core Society so it's only by making people these matters but also sensitive that we can create better series whether it's city planners using data to transform life from on high or citizens using data to build solutions from the ground up they're finding new ways to use
18:00 - 18:30 technology to tackle the challenges faced by modern-day mega cities they the fallacy and making sense of this data that we can change the cities of the future [Music]
