People Fixing The World

Women in a village in Northern Nigeria have come up with an emergency transport scheme that is saving lives. They decided to act when they saw mums-to-be and their unborn babies dying in childbirth because they couldn’t get to hospital in time. Their solution also inspired the state government to help thousands of other women. Produced and presented by Bara’atu Ibrahim (Repeat)

What would happen if the government of a country decided to try to find everyone who was homeless and living on the streets and offer them a place to live? That is exactly what happened in England as the coronavirus pandemic hit. The government says 90% of rough sleepers were offered rooms in hotels that sat empty because of the lockdown. Simon Maybin spent the past year and a half following the lives of some of the people who came to live in a Holiday Inn hotel in Manchester. Image: A guest at the Holiday Inn.

At the human library you borrow a person you wouldn’t usually meet for a half-hour frank conversation. The volunteers have various book titles from polyamorous to former prisoner. The aim of these face-to-face chats is to break down our assumptions and prejudices. We explore whether simple discussions can make a difference. Produced and presented by Claire Bates.

Two sources of greenhouse gas could be lurking in your kitchen: rice and fridges. We meet a biologist breeding climate-friendly rice, and a team of detectives whose job is to stop fearsomely potent fridge gases escaping into the atmosphere. Produced and presented by Jo Mathys and Tom Heap.

Wood is strong enough to build skyscrapers, and bamboo - the fastest growing plant in the world - can also be used for building. Both suck up large amounts of greenhouse gas. We find out what would happen if we used these materials instead of concrete in construction. Produced and presented by Jo Mathys and Tom Heap. Picture: Moelven

Seaweed - we have been using it for centuries in food and toiletries. It can help to keep toothpaste and ice cream soft, as well as being a tasty snack. It is a billion-dollar industry. But in some parts of the world, supply of the crop has decreased dramatically due to climate change. Now people in Zanzibar are fighting back. They are learning new methods of farming seaweed in deeper, cooler waters. It is boosting the amount of seaweed they can grow and improving their livelihoods as a result.Produced and presented by Celestina Olulode.

People in Kenya have been paid to catch swarms of locusts eating farmers’ crops. The insects are full of protein and the captured ones are ground up and put into animal feed. The BBC’s Nick Holland and Claire Bates find out what tricks these 'locust hunters' use to catch the critters and what difference the cull makes. They also hear about a way of capturing tiny micro-plastic particles that come off car tyres and delve into a clever project feeding homeless people in Mumbai.

The LGBT community in Mombasa, Kenya has suffered from violent mob attacks in recent years - often fuelled by influential preachers spreading messages of hate. But one group decided to tackle this in a remarkable way: they have directly engaged with faith leaders. In carefully controlled meetings the pastors and imams get to know LGBT people and have their misconceptions challenged. This has led to a big reduction in violence. Now many of those religious leaders use their influence to help the LGBT community fight discrimination wherever they find it. Produced and presented by Richard Kenny Picture: Getty Images

Sleek blue machines have been popping up in convenience stores across Nairobi over the past two years. These “Koko points” look like cash machines but instead of giving out money they dispense bioethanol, a fuel made from plants which can be used in cooking stoves.At the moment 80% of Kenyans use wood or charcoal as their main cooking fuel – but these materials have a devastating impact on the environment, and the smoke causes hundreds of deaths every week. Koko’s high-tech solution offers Kenyans a cleaner alternative, although it means a move away from some dearly-held customs. Reporter: Mercy Juma Producer: William Kremer

Recent years have seen remarkable successes against some of the most unpleasant illnesses on the planet. While much of the world’s focus has been on the fight against Covid-19, the battle against other diseases rages on. From the battle against hepatitis C in Egypt, to the war against metre-long parasitic worms, to the near elimination of sleeping sickness in the Ivory Coast, we hear the good news that you might have missed.

Dutch friends Evelien and Roel are part of a group sharing their social networks and local knowledge with Laila, a Syrian refugee, and her family. They’re taking part in a pilot project in the Netherlands called Samen Hier, which matches locals and newcomers. The idea is to help people who live nearby get to know one another and encourage integration. Produced and presented by Claire Bates Picture: Getty Images

A large study published in June showed how a peculiar intervention could help prevent the spread of dengue fever. Instead of vaccinating people, the World Mosquito Program has found a way to breed mosquitoes carrying bacteria that prevent them catching the disease in the first place. The organisation releases millions of these designer mosquitos into a city with the aim of displacing the wild population and protecting the human residents. People Fixing the World saw the method in action in Colombia in 2019 – this is another chance to hear that report, and get an update.

Scientists have hatched an incredible plan to save the northern white rhino from extinction. The team is using IVF techniques to produce a calf because the only two females left alive are infertile. Nick Holland reports on how close they are to succeeding and of their hopes to eventually release a whole herd back into the wild. Produced and presented by Nick Holland

This week we hear from Colombia, where a helpline with a difference recently opened. Its aim is to stop domestic violence, but instead of targeting victims, it targets the perpetrators. The idea is to get men in particular, who are struggling with jealousy, anger and other strong emotions, to phone in and get help. Produced and presented by Craig Langran Picture: Getty Images

The Sinai desert in Egypt is a dry, barren place where not much grows. But Ties van der Hoeven has come up with a scheme to turn it into a green and fertile land. It’s a plan on a huge scale which involves dredging a lake, restoring ecosystems, and even bringing back rain to the desert. He’s been inspired by a successful project to restore the Loess Plateau in China. But could it work in the Middle East?Produced and presented by Richard Kenny.Picture: Getty Images

Are stickers still saving lives? Was a coral reef repaired? Did the volcano erupt? In this episode we check back in with three projects that have featured on our programme over the past four years and find out if everything went to plan. We hear from the scientist who developed a sticker that stops car crashes, the people behind an insurance scheme for coral reefs, and find out if a plan to deliver aid before a disaster was up to the test.

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, looking for seeds and plants he could rescue. Now his forest is flourishing and the wildlife has returned - it is home to snakes, toucans, monkeys and many other animals. And he is sharing what he has learned to encourage others to protect the rainforests instead of cutting them down. Presented and produced by Jo Mathys.Repeat - first published 31 March 2020.
