Peru is famous for its diverse and innovative cuisine - but how is it making sure its venerable food heritage is preserved for decades to come? We meet the indigenous Quechua people who are cultivating more than 1300 species of potato, working with scientists to safeguard seeds in community banks as part of both ecological and cultural efforts. And we hear how communities in the high Andes are turning back to crops like quinoa and kiwacha in the face of climate pressures and the desire to boost nutrition.

Learning to read empowers people, reduces poverty and increases their job chances. Yet more than 700 miliion adults are illiterate, the majority of them women. We look at innovations to help adults learn how to read from flatpack classrooms in flood-prone regions of Bangladesh, to an app teaching tens of thousands in Somaliland. Plus how adults in the UK are improving their reading skills thanks to an army of volunteer teachers using a method developed in prison.

How do you save threatened species? This week we look at two novel solutions. In the UK, scientists are developing a unique contraceptive that will be fed in a nutty spread to grey squirrels, an invasive species that threatens the native red squirrel. And how scientists are moving albatross eggs thousands of miles from their low-lying home on Midway Atoll in the North Pacific to a Mexican island to try and protect the under threat Black-footed Albatross.

Organ transplantation has long been seen as a miracle of modern medicine but each year thousands of people across the world die while waiting for this life-saving operation. We’ll find out how one medical technology company based in the UK is cutting wait times for liver transplants after inventing a machine which simulates the human body. We’ll also visit South Africa which has one of the lowest rates of transplants globally because of a donor shortage and a lack of awareness. There, we’ll meet Zane - a unicorn with a Zebra leg who’s teaching children about ‘sharing a spare’.

Thousands of people in Sierra Leone lost limbs during the brutal civil war, and many more have struggled to overcome the mental as well as physical burdens of the conflict. We visit the Farming on Crutches programme where amputees are trained in agricultural skills which they can use to start their own farms and teach others in their communities their skills. Plus how former addicts are helping others in their communities to stop using kush, a deadly blend of addictive substances that has become a scourge in Sierra Leone and other parts of West Africa.

Many cities are becoming unpleasant to live in: they are getting hotter due to climate change and all the heat absorbed by the streets and buildings. But Stuttgart in Germany has been tackling this by carefully studying local wind patterns. Using the natural airflow they are cooling the city by creating corridors of wind from the surrounding hills. It’s an idea which is being copied by cities around the world such as Singapore. There we see how new buildings are being designed to allow a breeze to flow despite the continued development.

The US state of Alaska may be known for its rugged wilderness, but it’s also quietly leading a green revolution. We explore how an island community is powering itself through a locally built and managed microgrid - cutting out fossil fuels and slashing energy costs. And we find out how scientists are using native mushrooms to produce sustainable building insulation and cold fish storage boxes that could help promote sustainability both in Alaska and beyond.

A unique community in Chester in northern England, brings multiple generations together to encourage learning and connection. We explore how young children in the onsite nursery benefit from the time, attention and vocabulary skills offered by the older adults. Meanwhile the retirement home residents can benefit from increased social activity and a sense of purpose. We also speak to an intergenerational expert in Spain about the growing evidence that backs this new societal approach.

In some places, the nearest safe operating room can be hours or even days away. We find out about a portable operating theatre called SurgiBox that fits in a backpack and inflates in minutes, creating a safe surgical environment for operations almost anywhere. We meet the co-founder of the start-up behind it and see it put to the test, and speak to a surgeon who has used it to save lives far from a hospital. We also hear from Field Ready, whose engineers in Syria are using 3D printing to bring broken hospital equipment back to life, and we hear about Sudan’s Emergency Response Rooms — grassroots command centres where volunteers coordinate life-saving help and vital information in the midst of war.

In one of the poorest neighbourhoods of Mumbai, a quiet transformation is underway. Govandi has long been associated with poverty and poor health outcomes. But with the help of a civic organisation, the community has built vibrant spaces with children and women in mind— libraries, workshops, and leisure zones—defying the norms of city planning that can overlook such needs. We explore how trust, persistence, and grassroots collaboration turned a neglected area into a model for urban resilience and enjoyment.
