This week we have a host of great ideas inspired by solutions we've told you about in 2023.

We find out how scientists are using fake birds to help populations of seabirds to recover. By putting out model birds in restored habitats they trick the real ones into nesting there.

Then we have the heartwarming tale of Theo – a man in his seventies - and Bickel the dog. We look at how dog sharing can deal with loneliness and bring improved health and happiness.

And we uncover an innovative way of dealing with the scourge of Japanese knotweed - by turning it into paper.

Landfill sites are an icon of our wasteful society and the harm we cause to Planet Earth.

But around the world, people are trying to make these filthy places a little bit better.

We visit the human-built island in Singapore made of burned waste that has become a thriving ecosystem.

And in France, we hear how gas leaking from landfill sites is being collected as a source of energy.

Loneliness affects millions of people around the world and can have a significant impact on our mental and physical health.

In the Netherlands, they are taking the problem seriously, with a national coalition of organisations all trying to bring people together and build connections.

We visit a youth club teaching teenagers how to overcome shyness and social anxiety. Plus, we drop in on a soup-making session that's bringing the generations together, and breaking down stereotypes.

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.

Every year the world produces 400 million tonnes of plastic – the same weight as all the humans on earth.

Only a small proportion of this is recycled, and this isn’t proper recycling but “downcycling” – the new plastic is of a lower quality, meaning that almost all plastic eventually goes to waste.

But now French company Carbios is using enzymes to break plastic down into its chemical building blocks – which can then be used to make high quality plastic again.

So is plastic on the brink of becoming a resource like glass or aluminium, that you can keep on moulding and recycling again and again?

Millions of women around the world lack access to safe and hygienic menstrual products. But there are people trying to change that.

We meet the British student who learned to sew in lockdown and started making reusable sanitary pads for refugees. She’s helped distribute tens of thousands of pads and is now training refugee women in Lebanon how to make money by sewing the pads themselves.

We hear about a design project inspired by tea cups which has created an efficient way of washing reusable pads.

And in India we meet the woman who is challenging the stigma around periods with a comic book that’s being read in thousands of schools around the country.

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.

Heroin users in Scotland are being trained to spot when someone is about to overdose and to step in and help.

The training – which includes lessons on how to use the antidote naloxone - is often led by people who have themselves been addicts.

Taxi drivers and police officers are also being trained, and naloxone being widely distributed, as part of a push to save as many lives as possible.

Reporter Craig Langran investigates whether the approach is working.

In the midst of a crisis, sometimes the solution you need isn’t obvious. Today we meet the inventors who found fascinating fixes amid the chaos and destruction of disasters.

We visit the hospital that was painstakingly constructed inside a train, to treat Ukrainian civilians in a war zone.

We follow a team in Fiji who have created a mobile workshop, designed to travel to remote villages after natural disasters and repair and make items on the spot.

Finally we look at a medical robot that could soon treat injured people in places it’s too dangerous for human rescuers to enter.

Meet the oceans’ unsung hero - the humble sea cucumber. An animal in the same family as starfish that looks like a lumpy sausage and lives on the ocean floor could help with some of the impact of global warming, pollution from fish farms and damage from the fishing industry that are threatening some of the oceans most important ecosystems.

We meet the Australian researchers using drones to count the cucumbers to understand how their poo is helping coral reefs. And in Madagascar, we speak to the local communities which are learning to sustainably farm the creature, protecting the seas and increasing their income along the way.
