People Fixing the World

Tech companies have developed drones to drop pollen on orchards or shoot it at crops through pipes from tractors. They’re responding to a crisis in insect pollination as studies suggest numbers of both wild pollinators and farmed bees are declining. This could have a serious knock-on effect on how we grow our fruit and veg. But some experts argue high-tech alternatives are a short-term solution to...

New technology is helping in the fight against wildlife poaching. Computer scientists have created a programme that uses artificial intelligence to predict where poachers are going to strike; a new generation of smart cameras is catching the criminals red-handed; and the latest police forensic techniques are being adapted to investigate these crimes. The aim is to put a stop to the illegal trade o...

A short online test that reveals attitudes, opinions and thought processes is being used to help decide whether to give people loans. The idea is to use psychometric tests to give people with little or no credit history a better chance of getting support and investment. New ways of providing financial services are needed because 1.7 billion people have no access to any kind of formal banking facil...

This week we look at four brilliant inventions by children: a phone app to stop drivers missing road signs; a robot that is activated when a vulnerable person falls over; a tool to help fire departments predict the likelihood of wildfires, and a way to make your fish tank double as a vegetable patch for microgreens. The future engineers and scientists behind these innovations are aged between 12 a...

Can companies operate better without managers? We hear from people who’ve got rid of managers and say it has helped them do a better job, made them happier and saved money. But there are pitfalls, too. Co-ordination and hiring talent for what are usually considered top management jobs can be a challenge when there’s no traditional hierarchy. Produced and presented by Dina Newman. Picture credit: G...

Old ships, powered by the wind, are sailing small amounts of cargo around the world again to help cut pollution. Some of them were built more than 100 years ago. The shipping industry moves 80% of traded goods around the planet. But the diesel engines that propel modern cargo ships through the oceans burn the dirtiest type of fuel. Nick Holland speaks to sailors and brokers who, for the sake of th...

Scientists in Italy have discovered that trees generate an electrical charge every time the wind blows strongly enough to make their leaves touch one another. The researchers, from the Italian Institute of Technology, have managed to harvest enough energy this way to power 150 LED lights from a single leaf. We meet them, and others, who are trying to make use of untapped, natural sources energy. W...

A clever invention is saving the lives of hundreds of children. Pneumonia kills about 1.4 million children under five every year. Treatment with concentrated oxygen could save many of them, but the machines that make it need a reliable source of electricity. Some hospitals have frequent power cuts, though, which can be fatal. So scientists in Australia and Uganda came up with an innovative way to...

We all know that sport is great for our health - and if you’re talented it can bring you great riches. But this week we look at how sport is changing lives and giving hope to young people leading the toughest lives. In Cape Town, South Africa, a British surfer noticed how kids from poor townships hardly ever went to the beach. So he started giving them free surfing lessons. Now hundreds go along e...

There’s a technology on the block which has the power to change all kinds of things for the better. If that power is harnessed, it has the potential to end corruption, protect your online identity and a whole lot more. Start-up companies and charities are using it in everything from tuna supply chains to medical records and ID documents and everything in between. The technology is blockchain and o...

We visit farmers growing lettuce, herbs and strawberries indoors in the middle of cities. The plants are stacked up on shelves in vertical farms that use hydroponics and aeroponics to cultivate them. The idea is to grow food closer to where it’s eaten. At the moment, cities get most of their produce delivered from far away, but transporting it uses energy, while fruit and veg can lose their freshn...

People around the world are coming up with ways to make the world a quieter place, from portable sound barriers to schemes to stop people honking their car horns. The trouble is that noise from traffic, railways, builders, even neighbours, can have a huge impact on our health and wellbeing, according to the World Health Organization. One of the solutions we look at reduces decibel levels around bu...

Robot shuttles and buses on demand are being tested to persuade more people to use public transport. Tallinn in Estonia and Luxembourg have even made travel free. The aim is to tackle the impact of one billion cars on the world's roads, which have brought some cities to a virtual standstill. But in order to tempt people away from their cars new incentives are needed. Claire Bates tries out schemes...

It has taken him 40 years, but Omar Tello has turned a patch of exhausted farmland in Ecuador back into rainforest. One of his biggest challenges was repairing the soil. His land was so degraded he had to make enough new soil - from unwanted wood shavings and chicken manure - to cover the entire plot. That alone took about 15 years. He also travelled deep into the Amazon for days at a time, lookin...

Human sewage contains lots of valuable nutrients, so should we be recycling it? One of these nutrients is phosphorus, a key ingredient in fertiliser. We need fertilisers to meet the demands of the planet’s growing population, but there is a limited supply of phosphorus. Once it finds its way into the sea it becomes impossible to recover. And yet we all excrete about half a kilogram of the stuff a...

This week we’re in Rwanda, where some men are getting lessons teaching them how to look after their babies. As well as promoting gender equality it's helping to reduce the high levels of violence women there experience at the hands of their husbands and partners. People Fixing the World meets the people taking part and finds out how it works and what difference it’s making. Reporter Lily Freeston...

It’s a flightless bird on the edge of extinction, but a team in New Zealand is trying to stop it from going the way of the dodo. The kakapo is a large parrot that was once common in New Zealand. But its inability to fly, strong smell and habit of freezing when attacked made it easy to hunt for both human settlers and the animals they introduced. By the mid-1990s there were only 51 left. The remain...

“Fabulous idea” or “waste of money”? Clever observations from our audience about solutions we’ve covered on People Fixing the World. Many are funny and offer fresh perspectives. Regular listeners will know that as well as podcasts, we also make videos that we post on social media. Our viewers love to comment and ask questions, and this episode is made up of these thoughts. Among the solutions comi...

An idea used in video games is helping LGBTQ people in the Middle East talk safely online. Coming out can be particularly hard, especially if there are no support groups to go to. As a result, the internet is sometimes the only place people feel they can be open about their sexuality, seek advice, and meet like-minded people. But in some countries, opening up on websites to people you’ve never met...

People living in this block of flats sign a contract to socialise together for at least two hours a week. The new housing experiment in Sweden is aimed at the two age groups most likely to feel lonely: under-25s and pensioners. A former home for the elderly has been given a revamp, creating plenty of communal areas designed to encourage mingling between the different generations. While loneliness...

Men and boys are being taught how to tackle some of the uncomfortable truths about everyday sexism. Many don’t realise the extent of the problem - cat-calling, unwelcome comments and dominating behaviour are all things that women across the world put up with on a daily basis. This week’s solution looks at a project called the Good Lad Initiative in the UK, which is trying to help men understand wh...

If exercise were a drug, almost every single person on Earth would be prescribed it in the later years of their lives. The health benefits for older people are massive – it can help reduce the risk of dementia, type 2 diabetes, some types of cancer, depression, heart disease and more. But not enough older people are getting the benefits of this “miracle cure” – as the UK and Ireland’s Academy of M...

Women in Uganda are learning how to treat their neighbours for depression. That’s because there aren’t enough resources for professional care, especially for people from poor backgrounds. An organisation called StrongMinds sets up group therapy sessions across the country, and when clients come out of depression, some are trained to run courses for other women. People Fixing the World visits a ses...

What if all the energy used at the gym was directed towards helping others, rather than lifting useless weights and running nowhere on a treadmill? That thought struck Ivo Gormley 10 years ago. So instead of running on a treadmill, he started running to see an elderly person twice a week. A few friends liked his idea, and the Good Gym was born. Today, you can find the organisation in more than 50...

As thousands of people are moved in the evacuation of the area around the Taal volcano in the Philippines, Ecuador - which has more than 20 active volcanoes - is looking at how to protect people there. A scientist based in Quito has designed a system to forecast dangerous activity. The Red Cross is working closely with him, so they can now warn people of potential disaster further in advance - giv...
