Urban Permaculture, businesses, and land access

Hey Toby,
I'm a huge fan of your work and efforts.

I'm interested to know what you see as the biggest opportunities for permies living in urban centers to create new business models which fit in with the ethics of permaculture?

I'm also interested in your perspective in the seeming lack of arable land access in the city. Beyond brown and black space reclamation, public gardens, community gardens, rooftop gardens, what do you think are opportunities which are underutilized or unknown in urban spaces?

Thank you for your time and effort.

Sincerely,
John Paul

In our city, we had a piece of city land, overrun with Himalayan blackberry and unauthorized camps. The neighborhood decided to put in a food forest. (Swan Creek Food Forest)

We have public utilities. I fantasize about removing very maintained lawns and creating community gardens or small food forests on utility property edges.

Another idea I saw via Facebook, a few years ago, urban garden/wildlife corridors.
