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.Presenter: Myra Anubi Producer: William Kremer Reporters: Esperanza Escribano, Anthony Wallace Series Producer: Jon Bithrey Editor: Penny Murphy Sound mix: Gareth Jones

On this edition of People Fixing The World we meet people who’ve helped overcome long-standing cultural biases to create better outcomes for everyone. In India we hear about the social media campaigns which have helped city dwellers in Bengaluru see those who pick waste from rubbish dumps not as dangerous and dirty but as invaluable recyclers. In Nigeria we meet a traditional healer and a health worker who are collaborating to help improve the treatment of psychosis and break down some of the unhelpful attitudes towards severe mental health problems.Presenter: Myra Anubi Reporter/producer: Makuochi Okafor, Claire Bowes Series producer: Jon Bithrey Editor: Penny Murphy Sound Mix: Andrew Mills(Image: Chief Mukaila Yusuf, BBC)

From beavers in the UK to bison in Romania and jaguars in Argentina, ecologists around the world are reintroducing animals that once flourished in particular areas. The theory is, if done correctly, they can boost biodiversity and restore ecosystems with benefits ranging from reducing forest fires to tackling invasive species. But the strategy is controversial. Opponents say some species are no longer suited to certain areas and cause conflict with farmers, adding there is little evidence it works. Proponents admit some well-meaning projects haven’t worked in the past, but insist properly planned rewilding, which has involved all the stakeholders from the start, can be very successful. We take a close look.Presenter: Myra Anubi Reporter/producer: Claire Bates Series producer: Jon Bithrey Editor: Penny Murphy Sound mix: Gareth Jones
