People Fixing the World

Road accidents are the single largest cause of death amongst young people around the world. But a project in Kenya is making impressive progress in tackling the issue. It has deployed a small and very simple weapon, which has been proven to cut bus accidents by at least a quarter – a sticker. Also on the programme, how they’re making recreation space in Chile, but without knocking down any buildin...

Picking up money - that’s what Haitian’s nicknamed a movement seeking to solve Haiti’s plastic waste problem and reduce poverty at the same time. It was started by a man who saw a glimmer of hope in the devastation wrought by the 2010 earthquake: plastic bottles were clogging the beaches and filling the oceans with rubbish. But what if you could clear up the trash, give Haitians employment, and re...

Fariel Salahuddin is not the type of person you’d expect to see wandering around rural Pakistan, especially with a herd of goats. She’s a successful energy consultant who has worked around the world. But when she returned to where she grew up, Pakistan, Fariel decided she wanted to work on smaller projects to try to make an immediate impact and provide solar energy to poor, rural communities. This...

What do you do in a medical emergency when the equivalent of 999 or 911 simply doesn’t exist? After spending time in countries that lack public ambulance services, US paramedic Jason Friesen realised the problem wasn’t a lack of sophisticated ambulances, or the hi-tech medical equipment inside them, but the communication system necessary to get an injured person from A to B in time to save their l...

This is a story about what happens to your body after you die. In many countries, the current options are burial and cremation, but, both methods come with significant environmental impacts. We’re running out of space for burial in many places, and cremation carries the risk of toxins and greenhouse gases being released. For World Hacks, Sahar Zand travels to the US, where they’re using a new proc...

How do you fulfil your sexual needs if you have a disability? How do you masturbate if you have limited use of your hands? These are problems that most able-bodied people have probably never considered. But if you’re in this position it’s something you probably think about a lot. And it’s a problem which Vincent, the founder of a small NGO called Hand Angels, is trying to help with. His group matc...

The Data Donators Meet Becky. She suffers from arthritis and is in constant pain. Like lots of people – patients and doctors alike – she has a hunch that bad weather could be exacerbating the problem. It’s a question that has been asked for at least 2000 years, but we have never had the tools or resources to answer it. That is, perhaps, until now. Dr Will Dixon has set up a mass participation stud...

On the island of Jersey, postal workers don’t just deliver the mail. They also check up on elderly people during their routes. In a five minute chat, they check they’ve taken their medication and if there’s anything else they need. It’s popular with older people and their relatives, and the project has caught the attention of post offices - and health professionals - around the world. Could a chat...

Parents struggling with childcare costs in London are banding together to care for each other’s kids. They run a super-cheap nursery where mums and dads take on half of the childcare. It’s a throwback to the childcare movement of the 1970s but can it work in the modern age? Presented by Sahar Zand. Produced by William Kremer. Image: Drawing of a family / Credit: BBC

There are no sewers in Haiti. 26% of Haitians have access to a toilet, so a lot of the sewage ends up in the water supply. Currently, Haiti is battling the biggest cholera epidemic in recent history and thousands are dying. We travel there to meet a team of women who are trying to solve this massive problem. They have set up an NGO called Soil which delivers dry, compost toilets to peoples’ homes....

Could we build cities using solar panels instead of walls? That’s the dream that Huang Ming, a wealthy entrepreneur in China’s Shandong province, has had since the 1980s. He’s become known as the ‘Sun King’ after building a vast solar park, including a showcase hotel, to prove a new kind of solar architecture is possible. So why hasn’t it caught on? We check into a room in the solar hotel and exam...

An innovative housing project in Amsterdam is attempting a new way of integrating refugees into the local population. In prefab flats, refugees from the Syrian war live next door to young people in need of cheap rent. They eat together, learn language together, and develop the networks that researchers say are critical to successful integration. Presenter: Charlotte Pritchard Reporter: Jo Mathys I...

Air pollution is a huge problem for China, but did you know it’s actually getting better? The Air Quality Index in several cities is improving, because of a variety of experimental projects that are being rolled out. In this special edition of World Hacks as part of the #SoICanBreathe season, we are in Beijing to gather together some of the thinkers and entrepreneurs leading China’s efforts to cle...

Voter turnout is a problem around the world, particularly in local elections. But a small group of academics and activists in the US are experimenting with a new way of getting people to turn up and put their cross in a box – a lottery. Every voter is entered and one lucky winner gets a big cash prize. World Hacks investigates whether it works. Presenter: Kathleen Hawkins Reporter: Gemma Newby Pro...

Food waste is a massive global problem: the EU alone throws away 88 million tonnes a year. Much of this ends up in landfill and produces dangerous greenhouse gasses which contribute to climate change. In Europe 53% of food waste comes from households, and one woman has made it her mission to stop Danes throwing away food. We travel to Copenhagen to meet Selina Juul, a key part of Denmark’s food wa...

This is a story about how the most amazing ideas do not always work how you would like in practise. In theory it is so simple. You put disease-ridden water into a two litre plastic bottle, screw on the lid and leave it in the sun. After six hours on a cloudless day, almost all the bacteria and bugs that cause diseases like cholera and diarrhoea are killed or inactivated by the UV light and gentle...

The internet is awash with made-up news stories. It’s not a new problem, but the highly charged US election campaign forced people to pay attention. This week on World Hacks we’re speaking to some of those fighting back against what they see as a threat to democracy: the fake news epidemic. We hear from guests including Le Monde’s Samuel Laurent, Democratic State Senator Bill Dodd of California, a...

In Barcelona, they’re experimenting with a new way of designing the city. Superblocks are vast low-traffic zones, but they’re also deeply controversial. The aim is cut pollution and reclaim public space from the car, but does it work? World Hacks investigates. Presented by Sahar Zand. Image: A superblock from above / Image credit: Google Maps

In one of the most expensive cities in the world, students are moving in with older people who have spare rooms as part of a “homeshare” scheme. The young people in Paris get cheap accommodation and the older people get companionship and support in return. World Hacks reports on the generation-spanning friendships that are blossoming as a result. Presented by Sahar Zand. Photo: Monique and Mikyoun...

Most refugees do not have the right to work. In Jordan they’re running an experiment to find out what happens when they’re given that right. They’re handing out work permits to thousands of Syrian refugees in the hope of improving their lives and the health of the economy. Academics say it’s better for everyone, but in the local area – where unemployment is nearly 20% - they’re not convinced. Worl...

Some £600bn is sent home every year by overseas migrant workers, almost four times more than all the countries of the world combined spend on foreign aid. But far from home, many workers fear their families are not spending their money in the right way. World Hacks looks at a two possible solutions for giving them more control over how their hard-earned cash is being used. Presented by Sahar Zand....

One in three children in Peru was growing up too short for their age, stunted by a lack of the right foods in their diet. Then in 2005, the government put in place an innovative new system. They gave cash hand-outs to poor mothers but only on the condition that they had regular health check-ups and their children went to school. By 2014 the number of children growing up too small had halved. World...

Giving children lessons in how to think and learn for themselves can lead to dramatic improvements in results, according to education researchers.
