You are about to listen to a BBC podcast and I like to tell you a bit about what goes into making one.

I'm Siddhartha Cesset, an assistant commissioner of Podcasts for BBC Sounds.

I pull a lot of levers to support a diverse range of

podcasts on all sorts of subjects, relationships, identity, comedy, even one

that mixes poetry, music and inner city life. So one day I'll be helping host develop their ideas, the next

fact checking, a feature and the next looking at how a podcast connects with its

audience and maybe that's you. So if you like this

podcast check out some others on BBC Sounds.

This edition is a walk in the park, more specifically the Parker Dorda in

Northwestern Turin. The space which is around 40 hectares was once home to a sheet metalworks and tyre

factory supplying the Italian car giant Fiat. In the 1980s the closed, the area was abandoned.

Left behind were two long lines of 30 metre tall cooling towers.

And so here you can walk along the Dora River, sit on the grass, look across a dramatic

post-industrial landscape and if you come at a certain time of year meet a special group of urban forages.

Oh the fissile there's one right here so you see it's right here and right here and right here and the

catch that we were standing in before there's also a larger Italian fissile which hurt a lot more.

The Parker Dura is no ordinary park and Alexis Nicole Nelson is no ordinary forager.

On social media to her 5 million followers,

Alexis is also known as the Black Forager

and she's an expert at bringing the history of human interactions with nature and its food to life.

And so in this walk in the park she guided us from small patches of thistles to a chance discovery of wild lettuce.

A lot of people I feel like don't know that lettuce is an aster, not a brassica.
