What do we mean by ’empowerment’, ‘citizenship’ and ‘cohesion’? Stepheni tells her story of being a refugee in Wales to explain why welcoming, inclusive communities are better for everyone.

Imagine if you had no alternative but to leave everything behind that is dear to you…. For people looking for a place of safety, citizenship means ‘my humanity is acknowledged’.

John Parker: Why trees are better than people

Did you know that trees in urban areas can improve child development, reduce violence and boost house prices? John tells us about ‘nature’s air-conditioners’, and why we shouldn’t take them for granted.

The benefits of trees to human health are massive. Pregnant women who spend time close to green infrastructure have bigger, healthier babies. Children exposed to green infrastructure at a young age show less signs of allergies. Patients in hospitals recover more quickly and are discharged faster if they have a view over green infrastructure than a hard landscape or no view at all.

Josh Doughty: From west Wales to west Africa

The kora is a 21-string lute-bridge-harp used extensively in West Africa, which Josh learned to play under the Master player Toumani Diabate. Hear his beautiful music and listen to the extraordinary story of how he came to play the instrument.

One of the rules of the kora is that you don’t play it at night by yourself, because the spirits come and listen and corrupt your soul. But if you don’t fear the spirits and you listen to them, they have things to teach you.

Matt Callanan: How to change the world with £10

What would you do if you found a £10 on the floor? Matt introduces us to the We Make Good Happen project, a movement that promotes everyday good deeds.

On Groundhog Day, I hid a number of £10 notes around the city and put photos of their location on social media. It turned into a good deed treasure hunt.
