People Fixing the World

How do you pull subsistence farmers in Africa out of the cycle of poverty? All you have to do is help them produce more food than they need to survive. But to do that you need money and a new company in Nigeria has designed a smart way to provide it. Farmcrowdy connects farmers with online urban micro-investors. The investors finance the production of chickens, vegetables or grain and receive a gu...

A growing movement in the UK is devolving the power of catching speeding motorists from the police to the people. Police have been working with community volunteers, letting them use speed guns in a bid to protect their communities from fast traffic. But as more of these amateurs learn to wield the speed gun, it’s a solution that’s thrown up its own problems. Presenter: Harriet Noble Reporter: Dou...

When we think of peace talks we think of politicians from opposing camps meeting behind closed doors in wood-panelled rooms, hammering out the details of an agreement that both sides can accept. But that process hasn’t led to long term peace when it comes to the Israeli-Palestinian conflict. So is it a mistake to think that only governments can negotiate peace? The Minds of Peace initiative brings...

Could bilingual schools help bring peace to a seemingly intractable conflict? In Israel, the school you’ll go to is largely decided before you’re even born – by whether you come from a Jewish or Arab family. Communities learn separately and live separately and that, many argue, cements the hostility and misunderstanding of generations. So is the solution to bring them side-by-side? Hand in Hand is...

People can’t resist a prize, especially when there’s money to go with a medal, and for hundreds of years that basic human urge has been used to push humanity forward. When you focus minds and money towards a simple target, incredible things can happen - from the clock that won the Longitude prize money in the 1700s to the spacecraft that won the XPRIZE in 2004. Are there any problems that a big en...

Loneliness and isolation can trigger a host of other problems, particularly for our health. But a town in Somerset, in the United Kingdom, appears to have taken a big step towards alleviating the problem. A team in Frome has implemented a handful of simple ideas – getting people to talk about the problems they face and finding ways for them to re-engage with family, friends or social clubs – and t...

**This episode is a repeat from 23 January 2018** Naomi is not your average teacher. For one thing, she is only six months old. But in many schools across Canada babies like Naomi are a regular feature at the front of class. It is because of an education programme called Roots of Empathy, which is designed to encourage kids to be kinder. The idea is that because a baby cannot explain and externali...

Space is littered with junk – some pieces as small as a fleck of paint, and some as large as a London bus. So much of it is orbiting the Earth, in fact, that it poses a danger to future missions. But how can space be cleaned up? One way could be to catch the junk in a net, or to use a harpoon to grab it. A team in Surrey, in the UK, are launching a special spacecraft to find all of this out. Repor...

Being homeless is extremely bad for your health. Homeless people end up in hospital far more often, and when they get there their condition is often serious. We visit a London hospital to see how one innovative healthcare charity is rethinking caring for the homeless – and how a hospital visit can be an opportunity to do far more than just patch a patient up and send them on their way. Presenter:...

One of every five bird species could be extinct within the next century. Whether it’s down to the shiny glass office blocks materialising all over cities or the trawlers sailing ever-further out to sea to feed our growing population, our birds are seriously under threat. This episode looks at two particular successes when it comes to helping the world’s feathered friends: how Toronto has become a...

More than $20bn is spent on chewing gum around the world each year. A lot of that gum will end up stuck to the streets. That's why gum is the second most common kind of street litter after cigarette materials. In the UK councils spend around £50m each year cleaning up the mess. But British designer Anna Bullus had an idea - what if the sticky stuff could actually be recycled and turned into useful...

Social media and messaging apps play a role in the extremist “radicalisation” of individuals. Tech companies have tried to get better at identifying extremist content and taking it down, but some specialists advocate an alternative approach – to use these platforms to engage with extremists one-to-one, to confront them and talk them round. Last year, the Institute for Strategic Dialogue in London...

An app in Greece is helping people donate their leftover drugs to people who can't afford to buy them. So far the system has helped to recover and redistribute 13,000 boxes of medicine. Donors use the software to scan a unique code on the side of their boxes of unwanted drugs. The app automatically uploads details of the medication to a central database. They're then taken in by the country's netw...

You’re standing on a stage, blinded by a spotlight trained on your face, knees weak, hands sweaty. Someone from the audience calls out a random word and you have to immediately react and come up with an amusing sketch or skit. This is improv, the unscripted theatre form that seems like it would cause rather than cure anxiety. But across North America people with the mental health condition are sig...

Providing food for seven billion people is fraught with difficulty. Fertilising vast tracts of land and flying fresh vegetables across the globe comes at a huge environmental cost. But more and more people are turning to hydroponics - growing plants in water, without any soil. The idea itself is hundreds of years old, but new twists on the old technique are now shaping the future of food. We inves...

By its very nature, volunteering means you don’t get paid. But what if there was a way to compensate volunteers that also helped the local economy? The northern English city of Hull is trying an experiment with a new, local cryptocurrency called HullCoin - the first of its kind in the world. It’s a sort of community loyalty scheme, that can only be earned by doing ‘good deeds’ and can only be rede...

Naomi is not your average teacher. For one thing, she is only six months old. But in many schools across Canada babies like Naomi are a regular feature at the front of class. It is because of an education programme called Roots of Empathy, which is designed to encourage kids to be kinder. The idea is that because a baby cannot explain and externalise how it is feeling, children learn to recognise...

An English woman has championed a way to bring back community spirit to city streets and keep children fit. She creates pop-up playgrounds by regularly closing the roads to cars. Alice Ferguson began her project in Bristol and the idea is spreading around the UK. It is part of a much larger, global movement that thinks it can give children a better deal.

Up to 90% of the world’s coral could be dead by 2050, according to some estimates, unless we take radical action. Tackling climate change remains the central battle, but around the world scientists are working on projects that may give coral a greater chance of survival, or at least buy it some time. The World Hacks team investigates ‘super coral’ in Hawaii, an innovative insurance policy in Cancu...

World Hacks follows up on some of our stories from last year – going back to innovators around to world to see how their projects have developed. We hear updates on the app that lets volunteers donate their vision to blind people, the man making roads out of plastic and the compost toilets in Haiti that are turning human waste into soil. Presenters: Harriet Noble and Dougal Shaw Reporters: Amelia...

This week we hear about three small solutions trying to make a dent on some big problems. We hear about an outdoor gym made from melted-down knives. We talk to the scout leaders in Madagascar trying to break taboos around periods. And in London we visit the community fridge, where locals can donate and take whatever they want. Reporters: Amelia Martyn-Hemphill, Clare Spencer and Harriet Noble Pres...

In Southern Africa, over seven thousand women are infected with HIV each week. Many can't persuade their partners to wear a condom, so a new form of protection being tested in Malawi could be a real game-changer. It's a small silicon ring which encircles the cervix and releases antiretroviral drugs, lowering the women’s risk of contracting HIV. Their partners can’t feel it, and don’t even need to...

If you are a wheelchair user, travelling by aeroplane can be very difficult. Buses, trains and some cars are designed for people to roll into without getting out of their chair, but planes are not, which means an often painful process of moving between the chair and the airline seat – if this is even possible. This can potentially lead to injuries and can stop disabled people travelling by air. No...

Most Malawians live in rural areas and if they get sick, it can be incredibly difficult to get testing kits or medicines in time. Malawi's government has now opened up part of its sky to companies and charities who want to use drones to solve this problem, creating what’s being called the world’s first humanitarian drone testing corridor. World Hacks travels to rural Malawi to assess the opportuni...

Your chances of surviving a cardiac arrest while out on the high street are slim. It's estimated survival rates decrease by ten percent for every minute you don't get medical help. The nearest ambulance may be on its way but could take several minutes to arrive. But what if an off-duty paramedic was just around the corner and could help out? BBC World Hacks looks at a new alert system that informs...
