Mr. Trash Wheel is pretty cool:

I grew up on concrete with streets peppered by exotic callery pear and feral pigeons. It wasn’t until a friend moved to a neighborhood with big yards (for the city, anyway) that I saw cardinals, bluejays, cottontails, foxes, and nights lit up by fireflies.

I live close to that neighborhood now and the streets here are lined with willow oak, black cherry, and sycamore. So many woodland creatures and cool bugs, some of which are recorded on iNat.

But go a mile south to a redlined neighborhood and the canopy is sparse to none. The streets are lined with empty tree wells, usually sloppily paved over. Some years ago, the police installed bright white spotlights and surveillance cameras. Absolutely brutal stuff.

Baltimore City has an adopt-a-lot program, allowing residents to use vacant lots for urban agriculture or community projects. However, as stated in point 3, it can be difficult to keep them going long term:

One farmer, Rich Kolm, said urban farms in Baltimore are playing several critical roles: They are community centers, educational hubs and fresh food producers in food-insecure neighborhoods.

Kolm has overseen three separate farms on adopted land in the city, and now he works as a contractor to those attempting to do the same. Though he commended the city’s low-cost water access service that accompanies lot adoption, he said people may not want to start a farm under the program if the land could be taken away.

“The whole idea of agriculture is that you’re building something,” said Kolm. “The only way to do it well is to make it permanent. But the city’s attitude is that urban agriculture might be a means of raising property values so much so that the agriculture gets kicked off the site.”
