We visit the communities in Chile restoring vital wetlands in cities and towns.

Chile’s urban wetlands are under pressure from rapid development, pollution and neglect, yet they play a crucial role in storing rainwater, supporting wildlife and reducing floods.

We visit the southern city of Valdivia where local communities have restored damaged wetlands by clearing rubbish, replanting native species and designing parks that work with nature rather than against it. Their efforts have transformed unsafe dumping grounds into thriving public spaces.

And in the major city of Concepción, residents work to restore wetlands to help fight flooding by reconnecting fragmented wetlands to allow them to do their original job.

The group carrying on investigations when journalists are silenced.

Over the last five years, almost 200 journalists have been killed outside conflict zones, with reporters being murdered while investigating corruption, organised crime and environmental destruction. For World Press Freedom Day, People Fixing the World looks at the work of a pioneering organisation that is trying to help. Forbidden Stories, based in France, pledges to continue the work of journalists who have been killed, imprisoned or forced into exile. To help them do this, they encourage the use of a digital “safe box”, where reporters whose lives are at risk can keep notes and interviews, and which can be opened in the event of their death. This tool means that even if reporters die, their work can live on – but many reporters believe SafeBox helps keep them safe too.

We meet Laurent Richard, founder of Forbidden Stories. From Ecuador, Tamia Villavicencio explains how she is continuing her father Fernando’s work despite serious risks to her safety. And we hear how a network of reporters finished the investigations of Colombian journalist Rafael Moreno after he was murdered in 2022.

Greywater is the relatively clean waste water from baths, sinks, washing machines and dishwashers. It’s not drinkable but there’s still loads you can do with it. This week we’re finding out how greywater could help tackle water scarcity.

We’re meeting communities in the dry north east of Brazil who have installed simple systems to filter the water they use in their kitchen, showers or laundry so that they can reuse it to water crops, fruit trees and provide food for animals like cows, goats and sheep, helping them to make a livelihood.

In Germany we meet the company using bacteria to help magically recycle greywater on a big scale in hotels, museums and swimming pools. Plus we talk to a greywater fangirl for her top facts and tips on how you can save water the low tech way.

Breast cancer is the most common cancer in women globally. The earlier it is diagnosed the higher the chance of survival. Treatment, even when successful, can lead to arm swelling, muscle weakness and low mood. But archery is helping women in Spain overcome both the physical and mental challenges of breast cancer treatment. We visit one group and find out how the sport has increased their strength and confidence and even drained painful swellings.

We also visit a breast cancer survivor in Uganda, who has set up a business making local and affordable prostheses for women who face stigma after losing breasts to the disease.
