Transforming the global food system is vital in the fight against climate change. Currently, food production accounts for a third of all greenhouse gas emissions. At the same time, the food system also fails to properly nourish billions of people worldwide.

In this edition of People Fixing The World we’re looking at high and low tech solutions to transform the ways we produce and consume food to make it greener and more equitable.

In London, we visit a startup company making cheese from genetically modified microbes rather than cattle, in a bid to make dairy production better for the planet.

And in Philadelphia we look at how planting fruit and nut trees in ‘food forests’ is tackling hunger by providing access to healthy, nutritious food for low-income communities across the city.

Making life easier for older people

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.
