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 water used for laundry to water their crops and save their land from desertification. 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.

The eco-tourism that is helping to protect mountain gorillas in Uganda.

Myra Anubi is in Uganda visiting the Bwindi Impenetrable Forest. It’s one of the few places that gorillas still exist in the wild, and even better, in recent years their numbers have actually been rising and they are no longer considered critically endangered.

This is partly down to the hard work of Dr Gladys Kalema-Zikusoka and the Conservation Through Public Health organisation. They engage with communities living close to the gorillas, who were often poaching them and destroying their habitat, to help them better understand the animals and tap into the potential for eco-tourism. They also encourage other forms of enterprise, supporting local coffee farmers with training and investment.

Myra meets former poachers now involved in conservation and speaks with local farmers - often women - who look after the coffee plantations. She talks to the village conservation teams involved in protecting the gorillas. And of course, goes into the forest to get a glimpse of these incredible creatures herself.

Exploring style and beauty for people with disabilities.

What we wear helps us express ourselves and communicate to others in the most immediate way. But the tools we frequently use to do that, such as clothing and haircare are not available to everyone equally.

One in six of us has a disability of some sort - according to the World Health Organisation - but most clothing and beauty brands don’t take account of that. From making shops accessible to catering for differences in design and size, few companies address these particular needs.

This week on People Fixing The World we’re talking to people trying to change that. Hair and Care is a London-based hairstyling workshop which helps people with visual impairments take better care of their hair.

Plus we bring together two entrepreneurs who’ve brought adaptive clothing to Africa and Asia allowing people with disabilities to fully express themselves in the way they dress. We also meet the UK-based adaptive clothing company that could affect the way we all dress – by working with technology companies to develop a scanner that will help in tailoring for all body shapes.
