Barcelona in Spain is famous for its beautiful streets, lined with tall apartment buildings. But the architecture is a problem for many people who have lived for years in upstairs apartments but who now find the stairs unmanageable.

In 2008, a survey found that in one district there were 300 people who could not leave their homes alone. A group of volunteers decided to do something about this and got hold of a special wheelchair with caterpillar tracks, so it can be used to take people up and down stairs. After an initial pilot scheme they launched a local service called “Let's Go Down to the Street”, to help elderly residents go shopping or meet up with friends. Sixteen years on, the service is offered across the city.

Plus we visit a home for senior citizens in an unlikely location: a university campus. The Mirabella complex at Arizona State University in the US offers its residents the chance to sample the college lifestyle – from lectures to shows and sports fixtures.

Shipping containers are a staple of global trade, helping in the transport of all sorts of goods by sea across the world. But their relatively cheap cost and sturdy structure lends them to many other purposes. In this episode we look at a start-up business in the UK that uses shipping containers to store carbon captured from the air in the production of building materials. And we visit a school for poorer children created out of shipping containers that sits in the middle of a busy intersection in Mumbai, India.

What do you do with your waste if you live somewhere that doesn’t have the infrastructure to deal with it? Turns out there are some really simple solutions. Presenter Myra Anubi is in Malawi where she meets the cafe owner in the capital Lilongwe who has set up a recycling hub as well as the women making valuable compost from food scraps and animal dung. Plus Myra visits the Kibébé workshop in the Dzaleka refugee camp where refugees are finding employment and meaning by turning used materials into clothing and toys.

Mindfulness meditation, which involves becoming aware of the breath in the present moment, has been a core part of Eastern contemplative practices for thousands of years. Over recent decades however, it’s ‘exploded’ throughout the West as scientists have sought to prove the physical and mental benefits of regular practice - like feeling calmer, less stressed and feeling better able to manage emotions.

This week we look at some of the more surprising places where these simple techniques are having a big impact.

In Kenya, we learn about the ‘mindfulness revolution’ that took place in a men’s high security prison outside Nairobi after a group of inmates and guards were taught mindfulness techniques in 2015. They soon started teaching each other and ten years later it’s spread to prisons throughout the country and beyond.

And we visit Baltimore in the US, where a non-profit organisation has been teaching mindfulness and yoga in inner city schools for over twenty years, giving children growing up with violence and deprivation the tools to manage their emotions and heal trauma.
