  1. The Ring That Could Help Save Women’s Lives

    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. Lees meer

    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 know it’s there.

    World Hacks meets the women pioneering this approach and taking control of their own protection.

  2. How to Get Wheelchairs on Planes

    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. Lees meer

    Now, a small group of amateur campaigners is trying to change this – designing and testing their own systems that would let their loved-ones travel the world in safety and comfort.

    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 opportunities and dangers from this new technology, and to see how much Malawians could benefit. Lees meer

    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 people with first aid training when they're in the vicinity of a medical emergency. Nick Holland investigates whether it works work and what difference it could make to survival rates? Lees meer

    A retired police detective and a former neo-Nazi leader may seem like an unlikely partnership. But Dr Bernd Wagner and Ingo Hasselbach have taken their past differences and used them as the basis for making a real change. When Hasselbach quit neo-Nazism over two decades ago he and Wagner, who had once arrested him, realised they had a shared dream: to help far right extremists change their ways. Lees meer

  6. How Iceland Saved Its Teenagers

    Beluister deze aflevering
    In 1998, 42% of Iceland’s 15 and 16 year-olds reported that they had got drunk in the past 30 days. By 2016, though, this figure had fallen to just 5% and drug use and smoking had also sharply declined. The action plan that led to this dramatic success is sometimes called “the Icelandic Model” – and strikingly, it does not focus on tighter policing or awareness campaigns to warn children off bad habits. Instead, top researchers collaborate closely with communities on initiatives like parental pledges and night-time patrols after dark, while the government invests in recreational facilities. But is being a teenager in Iceland still fun? Lees meer

    Thousands of places in the world don't officially exist on a map. If you're not on a map, it can have implications for how people find you - in times of disaster for example. But a project called Missing Maps is solving that, by using the power of volunteers to make 'invisible people, visible'. At a mapathon in London, volunteers are sitting around their laptops plotting the world. And then in Malawi, mapping experts are putting in essential details to the map. World Hacks travels there to see the finished maps and what impact they could have on communities living there. Lees meer

    to stop people getting caught short.
    What do you do if you're out and about and can't find a public toilet? Do you sneak into a cafe and hope no one notices, buy something you don't want just for the privilege of using the facilities, or hold it in until you can get home? The number of public toilets around the world is decreasing, making this an increasingly common dilemma. But not in many parts of Germany thanks to a scheme called "Die Nette Toilette", or the nice toilet. Local authorities pay businesses a monthly fee to let anyone wonder in and go to the loo for free. Not only does this dramatically increase the number of available toilets, it leads to big savings for the public purse.

    Around 75% of the world's population, approximately 4 billion people, don't have an address. Take a country like Mongolia, with a largely nomadic population, where street names and postcodes can be few and far between. But that could all be changing thanks to just three words. Mongolia's Postal Service was the first in the world to sign up to What3Words, an idea from a British former music executive fed up of bands and equipment constantly getting lost. He's divided the entire world into 3m squares and given each one a different three word phrase, and it could mean that everyone in the world will soon have an address. Lees meer

    Although Iceland is thought to be the best country in the world for gender equality, it lags behind in one metric: the gender pay gap. So a decade ago the country's unions and business community came together to try something new. They devised a management standard to help organisations implement equal pay. Now the government has gone a step further and introduced a law that from January will force companies to adopt the standard or face fines. So is this small island nation set to be the first in the world to equalise pay? Lees meer

    It’s not usually a good idea to take selfies of your private parts, but what if those photos could save your life? A new, tiny medical device is being used across Africa to detect cervical cancer from a mobile phone photograph. In Gambia, doctors are often in short supply, but nurses, midwives and smartphones are widely available, allowing patients to be diagnosed and treated remotely. In sub Saharan Africa, cervical cancer is the number one cause of cancer deaths in women, but it takes years to develop and can be treated for under $30 if caught early. Can cervical selfies get women talking about a silent, unseen killer? Lees meer

    Humanity’s hunger for meat is not good for the planet. Every cow, pig and fish that farmers rear has an environmental cost – particularly in the land and water resources it takes to grow the food the animals eat.

  16. The Dutch Antibiotic Revolution

    5 september 2017 · 23 min

    Beluister deze aflevering
    Antibiotic resistant superbugs are a huge problem both in humans and in animals. Many animals reared for food are routinely fed antibiotics to prevent infections. Farmers across the world do it to protect their livestock and to safeguard their incomes. But some bugs are becoming resistant to these drugs because of their overuse – fuelling the rise of animal “superbugs” like MRSA that could potentially spread to humans. This means that animals and people can die from common infections because the antibiotics no longer work. In the Netherlands, the story of one sick little girl caused pig farmers to wake up to a huge pig MRSA infection that was spreading to humans. Recognising the problem, a couple of pig farmers started a movement that has resulted in the country cutting their antibiotics use in animals by 65% - and, crucially, without affecting their profits. World Hacks investigates how a group of pig farmers solved a massive problem in The Netherlands and whether other countries should urgently follow suit. Lees meer

    How do you help female doctors get back to work when they've given up medicine to look after their families? It's a particular problem in Pakistan where the majority of medical graduates are women who stop working after they get married. Now a scheme has been set up employing them to hold video clinics with patients over the internet, enabling them to work flexibly from home. What's more they're aiming to improve access to health care in Pakistan by targeting their 'computer screen clinics' at people living in deprived parts of the country, where the shortage of female doctors is most acute.

    Is a new urban cable car in Mexico more than just a means of public transport? As well as ferrying thousands of people a day, it's been strategically located to link up the poorest neighbourhoods to more affluent parts of the city. It's hoped it will bring growth to a forgotten district, reduce crime and become a means of bridging the social divide. World Hacks travels to Mexico City to see if it can achieve those goals and understand why cities are opting for this usual form of transport. Lees meer

    Around the world, governments and researchers are experimenting with the introduction of universal basic income. From Finland and Spain to India, the idea of giving every citizen – whether working or not – a set amount of money per month is gaining momentum. It’s claimed to be a fairer and more efficient way of running a welfare system, but we’re only just starting to understand what actually happens when you introduce a basic income for everyone. We look at the evidence and try to establish whether it is an idea whose time has come. Lees meer

    Darius has been shot three separate occasions, but the third time was the last. He was met at his bedside by a stranger, who changed his life forever. Lees meer

    Victims of violence are, far more likely to be shot, stabbed or violently assaulted a second or third time - as the perpetrators of violence try to silence the victim.

    In San Francisco, where Darius lived, specially trained case managers visit victims of violence at their bedsides in hospital and work with them to break that cycle of violence, offering practical advice and specialist services to the patients.

    They claim that speaking with victims of violence immediately after an attack, when they are experiencing a 'teachable moment' they have a far greater chance of changing the patient's life forever.

    Reporter Sam Judah meets Darius at the site of his third and final shooting, tracing his journey to the hospital, and his meeting with the youth worker who helped him turn his life around.

    How do you get children who're victims of emotional abuse or physical harm to open up about what's happened to them? In Mexico a psychologist, Julia Borbolla, encourages them to have a one-to-one chat with a cartoon alien that appears on a video screen in a room near her office. What the children don't realise is Julia hears every word of their conversation with the animated creature because she's secretly controlling it from the room next door. Lees meer

    She says children are more likely to reveal sensitive information to the cartoon alien than if they were face-to-face with a real person. World Hacks travels to Mexico City to assess whether the tool works and to meet people who're now operating it in public hospitals, women's shelters and within the country's judicial system.

  23. Cutting Cow Farts to Combat Climate Change

    18 juli 2017 · 19 min

    Beluister deze aflevering
    Methane emissions from the burps and farts of livestock accounts for around 15% of global greenhouse gas emissions. But the trick to reducing this could lie with some of Kenya’s smallholder farmers. By using very simple techniques to transform the way they manage their soil and animals, dairy farmers are helping their cows emit less methane per litre of milk they produce. And it’s all being paid for by big polluters, in what could become a major form of carbon offsetting. Is this a new frontier in the fight against climate change? World Hacks has been to rural Kenya to find out. Lees meer

    World Hacks goes to Thailand to meet an army of volunteers on the front line in the fight against dangerous diseases, like Ebola and bird flu. Lees meer

    Nearly 100 years ago Spanish Flu infected a third of the world’s population and killed about 50 million people. With increased international travel, growing populations and environmental damage, experts warn that viruses now have the potential to spread faster, and we could be on course for another pandemic, with devastating consequences.
    Pandemics often originate in places where animals and people live in close contact, making it easy for animal diseases to spill over into humans, and where health systems may not be able to pick up on threats and respond quickly. In rural Thailand, 75% of people keep animals in their back gardens, making it hard to keep track of new outbreaks. In 2004, a strain of bird flu swept through the country, as well as Vietnam, Cambodia and Indonesia, infecting more than 125 people and killing about half of them.
    Vets at Chiang Mai University have started a project called PODD – the full name in Thai means “Look closely and you will see”. They’ve trained up 3,000 volunteers to take photos of dead animals and report any signs of sickness in their communities, helping spot dangerous outbreaks and contain them before they spread.

    AltSchool believes it can achieve results that were only previously possible by giving individual children their own personal tutor.

    The firm currently runs eight small ‘lab schools’ dotted around the country, all run from their California headquarters. But they have huge plans for expansion, and hope to sell their software to every school in the country.

    Sam Judah meets the pupils at one of the schools, and the CEO at AltSchool’s nerve centre, to find out what’s behind the company’s big idea.

    Thailand in the 1960s was on the verge of a population disaster. Thai women were having seven children on average, and the government was struggling to raise living conditions. Mechai Viravaidya, a young economist who moonlighted as a soap actor, newspaper columnist and teacher, made it his mission to get family planning into every village in Thailand - he wanted to make condoms as easily accessible as vegetables. Lees meer

    Mechai realised he could use humour to break down Thai reservations about contraception, launching condom blowing competitions and condom beauty pageants. His efforts were so successful, condoms became known as “Mechais” in Thai, and he was nicknamed “The Condom King” or “Mr Condom”. When the HIV/Aids crisis threatened to engulf Thailand in early 1990s, Mechai, now a government minister, launched a mass media campaign promoting condom use and made condoms available everywhere, from massage parlours to bus stops. It is estimated these preventative measures saved 7.7 million lives. We find out what lessons we can learn from his 45 years of campaigning. Presented by Mai Noman.

    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? Lees meer

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.

    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. Lees meer

    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.

    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? Lees meer

    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. Lees meer

    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.

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. Lees meer

  39. Toilets in Haiti and Circular Runways

    There are no sewers in Haiti. 26% of Haitians have access to a toilet, so a lot of the sewage ends up in the water supply. Currently, Haiti is battling the biggest cholera epidemic in recent history and thousands are dying. We travel there to meet a team of women who are trying to solve this massive problem.
    They have set up an NGO called Soil which delivers dry, compost toilets to peoples’ homes. Alternatives to water guzzling flushing toilets - which need infrastructure such as sewers - are drastically needed in many parts of the world. And there’s a bonus to this scheme too.

    Also on the programme, a radical suggestion for airports: build circular runways. Are the current straight ones really the best way to take off and land?

  40. Checking out the solar hotel

    Could we build cities using solar panels instead of walls? That’s the dream that Huang Ming, a wealthy entrepreneur in China’s Shandong province, has had since the 1980s. He’s become known as the ‘Sun King’ after building a vast solar park, including a showcase hotel, to prove a new kind of solar architecture is possible. So why hasn’t it caught on? We check into a room in the solar hotel and examine the vision and sometimes unfulfilled dreams of solar architecture in China.
    Plus, why do bins in Copenhagen have shelves built into them? Clue: it helps the city’s poorest people.

  46. The Sun Water Solution

    This is a story about how the most amazing ideas do not always work how you would like in practise. In theory it is so simple. You put disease-ridden water into a two litre plastic bottle, screw on the lid and leave it in the sun. After six hours on a cloudless day, almost all the bacteria and bugs that cause diseases like cholera and diarrhoea are killed or inactivated by the UV light and gentle warming. Professor Kevin McGuigan has proven this in the lab, but for the last 20 years he has been trying to get it working in rural African communities. It has not been anywhere near as easy as you might think. Lees meer
