People Fixing the World

There are more than 200,000 women in US prisons and jails and it is estimated that 6% to 10% are pregnant. One project in Minnesota is trying to use these pregnancies to change the lives of the women, and their children, for the better. We go to jail with the Minnesota Prison Doula Project to see how it works.Presenter: Mukul Devichand Reporter: Sahar Zand Producer: William Kremer

Globally, only around 20% of clothes are re-used or recycled. The majority go to landfill or are incinerated. In the USA alone, the amount of clothes being thrown away has doubled in the last two decades. In World Hacks this week we meet the Scandinavian entrepreneurs trying to change this. Could a solution to this waste be to give people the option of renting clothes, so they don’t hoard things they rarely wear? Or how about clothes you can throw away guilt free, because they are fully compostable? Presenter: Mukul Devichand Reporter: Dougal ShawImage: Man wearing boxer shorts / Credit: Houdini

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 buildings. Presenter: Tom Colls Producer: Harriet Noble [Image: Mutatu buses in Kenya.

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 reduce the reliance on “virgin” plastic, all at the same time? It’s a bold idea that aims to solve two of the World’s big problems – poverty and plastic in the ocean. And it all hinges on attaching social value to recycled plastic. So why aren’t more companies doing it?Presenter: Sahar Zand Reporter: Gemma Newby(Image: Plastic rubbish on beach in Haiti, Credit: BBC)

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 was all very well, until she realised these places didn’t have water, let alone power. What they did have was goats. Fariel developed an innovative scheme to trade what the villagers have in plentiful supply for something they desperately needed: goats for water. But what was Fariel going to do with all her newly acquired goats?

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 life. In the Dominican Republic there are no public ambulances but now, in two rural areas, first responders respond to a medical emergency as fast as any ambulance service in the developed world. And all it takes is one smartphone, a handful of willing volunteers, and an Uber-like text system that crowdsources help when disaster strikes.And Dougal Shaw meets the man who is pioneering a way to use recycled plastic to make stronger, longer lasting roads.Presenter: Sahar Zand Reporters: Gemma Newby, Dougal Shaw.Image: First responders in the back of an ambulance / Credit: BBC

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 process to deal with the dead. It’s been called “green cremation,” “water cremation” or “resomation” and uses alkaline hydrolysis to mimic and accelerate the breakdown of tissue that would occur in burial. Those who invented the process say it’s an environmentally friendly way to address this fundamental moment in the human life-cycle, but does the evidence stack up?Reporter: Sahar Zand Presenter Mukul DevichandImage: A resomation machine / Caption: BBC

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 matches volunteers with disabled people to provide a sexual service. Mukul Devichand and Alvaro Alvarez go to Taiwan to hear the remarkably frank stories of the volunteers and the receivers at the service. They open up a world of deep disappointment of those people who haven’t experienced sex or intimacy and an organisation that thinks it has the solution. But can any service ever fill this gap or is it just a shallow fix. Presenter: Mukul DevichandImage: Vincent – the founder of ‘Hand Angels’ / Credit: BBC

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 study that takes advantage of smartphone technology. More than 13,000 people have downloaded an app that has provided his team with a massive set of data, and by combing through it he hopes to answer the question once and for all. It’s not the only project of its kind, either. Around the world more and more people are launching similar projects – asking thousands of volunteers to donate their data for the greater good.Presenter: Mukul Devichand Reporter: Nick HollandImage: Overlay of highlighted bones of woman at physiotherapist / Credit: Shutterstock

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 on the doorstep help solve the social care crisis? We travel to Jersey to meet the man behind the idea, and join a postman on his round.
