In 2019 a group of prison officers from Philadelphia in the US spent three weeks working in jails across Scandinavia - in order to see whether their more humane approach to custody could work back at home.Five years on we visit SCI Chester’s ‘Little Scandinavia' to see whether the ‘homely’ environment - where prisoners can order groceries, cook their own meals and socialise with officers – leads to better behaviour.We’ll also head to Panama, where an innovative recycling project is cleaning up a prison and providing inmates with skills they can use once back in the outside world.People Fixing The World from the BBC is about brilliant solutions to the world's problems. We'd love you to let us know what you think and to hear about your own solutions. You can contact us on WhatsApp by messaging +44 8000 321721 or email peoplefixingtheworld@bbc.co.uk.
