Women in a village in Northern Nigeria have come up with an emergency transport scheme that is saving lives.

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 l...

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.

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 wate...

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...

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 t...

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 en...

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...

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...

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 popu...

Former criminals are being employed to run part of the probation system in one of America’s deeply troubled, gang-ridden communities. It’s a bold new approach to crime prevention, and it seems to be working - young lives are being transformed and reconviction rates are dropping. Produced and presented by Jo Mathys

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.

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 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 Middl...

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 delive...

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...

There are thousands of oil and gas platforms in the world’s oceans and in the coming decades many will become obsolete. Some people think that instead of treating them as industrial waste, we should embrace the ecosystems they’ve created and leave them in the sea as artificial reefs. This approach has been adopted by some US states, and scientists are considering whether this could also work in th...

Scientists are checking up on the health of forests by analysing the sounds in them. They test their vital signs by measuring the croaks, tweets and hums of resident creatures. If they can hear a full range of animals they can be confident an ecosystem is doing well. However, if gaps start to appear, it’s a sign something is up. Nick Holland hears more about how it works and how it’s being used to...

This is the story of how one man is trying to transform lives through the power of the humble bicycle. Many rural communities in rural Africa don’t have access to cars or good roads, which can make it hard to take fresh produce to market or get to school. But Wyson Lungu wants to change that with an innovative scheme to sell affordable bicycles. We follow him as he delivers a new set of bicycles t...

Machines to shred, melt and mould waste plastic are popping up in workshops around the world - from the UK to Malaysia, Kenya to Mexico. The project is being led by an organisation called Precious Plastic. They put designs for the devices online for anyone to download and build themselves. More than 400 teams around the world are now taking on the challenge of plastic waste using these machines, m...

Irrigation pipes have been designed to double as mid-air walkways to help slow lorises cross open farmland in Indonesia; and a footbridge has been built for a rare breed of monkey in Brazil - the golden lion tamarin. These are just two examples of new infrastructure designed to help wild animals cope with human obstacles. Picture credit: Little Fireface Project
