The global rhino population has fallen by 95% since 1900, mainly due to poaching. Now an atomic approach is being used to stop the poachers in South Africa by placing radioactive material into the horns of rhinos. We journey to the South African bush to meet the scientists - as well as the rhinos being protected.

How do you stop people chopping down precious rainforest? In the Indonesian part of Borneo, researchers for a conservation charity discovered that local people were chopping down the rainforest around them for an incredibly understandable reason – they needed to pay for medical treatment for themselves and their children.

So they started a project that would hopefully protect the forest and help the local communities at the same time. They built a health centre and gave people a big discount on medical care if they stopped chopping down the trees. Ten years on, we visit the forest to see what happened next.

In the red light districts of Kolkata, India, there exists an extraordinary youth club. DIKSHA, as it’s known, looks after the children of sex workers when their mothers are working. While they’re at the youth club, girls and boys learn about their rights and are empowered to take control of their futures. Since the club started in 2001 it has worked to prevent girls from joining the sex trade, and helped reduce the stigma facing children in the wider community. Reporter Puja Bhattacharjee meets the people behind the club and the families benefitting.

Around the world, rubbish is collecting in our gutters and waterways, with millions of tonnes being washed out to sea every year. As the soup of ocean debris kills and injures millions of marine animals, we look at two projects trying to make a dent in the problem. We discover a Greek project which has enlisted thousands of fishermen around the Mediterranean to collect rubbish from their nets, rather than throw it back. They then sort it and hand it over for recycling when they return to port. We then travel to Accra in Ghana where a group of volunteers called the Buz Stop Boys are busy clearing the streets of rubbish. They hope their noisy grassroots movement will inspire others to take responsibility for public places and stop rubbish being washed out to sea. And we hear from Teddy, our youngest problem fixer yet. The six year old from the UK has stopped thousands of sweets tubs from going to landfill, proving you're never too young to fix the world.

Globally, energy production and use is responsible for around 75% of the world’s carbon emissions, with around a third of that on electricity and heat alone. To tackle climate change, we need to get more energy from renewable sources, so this week we’re taking a look at some of the more surprising ways people have come up with to harness clean energy from the world around us.

In the United States, we see what happened when a group of concerned mothers forged a surprising alliance with a gas company, and worked together to get clean energy from the ground beneath their feet.

In Madagascar, we meet the grandmothers bringing solar light to their remote villages, plus we visit Wales, where an innovative new technology is harnessing power from the tides – by flying “kites” underwater.

The World Health Organization (WHO) estimates that one in every 100 people in Gaza have a life-changing injury because of the conflict. It’s currently impossible for most to leave the strip and get medical treatment but a team of Jordanian medics has been able to enter Gaza and fit war victims with cutting-edge prosthetics which clip on quickly and easily. The BBC’s Yolande Knell in Jerusalem has been hearing from innovators, doctors and those who are being helped about how the new technology works and how it could help in other parts of the world, either in conflict or in healthcare provision more generally.

Sex is one of the few things in life that is available to everyone and is free. But achieving enjoyable sex is not possible for many. Some people are held back by fear, ignorance or culture - others don’t know or understand their rights around sex. For years public health campaigns focused on warning people about the downsides of sex - danger, disease and death - but increasingly the work is focused on the reasons people have sex. We're in Brazil where we meet Ana Autoestima. She’s a ‘virtual friend’ who provides positive advice about sex to women living some of the poorest neighbourhoods in Rio de Janeiro. We also visit Iraq to find out how a project is helping women who’ve suffered from female genital mutilation or FGM to enjoy their bodies and sexuality. And we’ll hear from Kenyan celebrity and musician Kaz Karen Lucas whose mission is to change the way Kenyans think about sex.

Billions of people struggle to make ends meet a lot of the time. We look at ways in which people who don’t have much money or are in financial distress can make what they do have go further. We visit savings and credit groups which are helping women to start businesses in Guatemala and see how a cooking at home scheme is helping to save cash - and improve diets - among some of the most vulnerable people in the UK.

Many agricultural workers don’t have the eyesight they need for the work they do, affecting both their comfort and their ability to earn more money. They're among the billion plus people who have visual impairments but can't get the assistance they need. We visit a coffee plantation in southern India where workers are being given glasses on the spot. As well as easing eye strain, the intervention has been shown to increase workers' pay significantly.

In the farming community of Los Negros in rural Bolivia, the river is their life and livelihood. So when that river started to dry up, it made life very hard. They blamed the villages upstream for not looking after their precious water.

This conflict could have turned ugly. But with the support of a local charity, what came out of it instead was a ground-breaking agreement. After years of negotiations, the town at the bottom of the river agreed to support the communities upstream to protect their forests and keep the river healthy.

The idea is now the blueprint for water sharing agreements between communities across the continent.
