There is a similar organization here, just plants, no livestock, but its really something to appreciate, and see old building lots and or suitable spaces within the city being used like this.
They have one large garden, and greenhouses not to far from a friends house in the nearby city, in a neighborhood you would not walk thru without fear, which I experienced first hand many times trying to get home from school as I had to take a city bus if I stayed after regular hours, sports or other activities. Instead of old brownstones filled with people wanting to do you harm, now theres a big ole garden. At the time, I wished the whole area would burn to the ground, having gotten chased by stick wielding, rock and brick throwing "natives", and you had no other choice, parents did not taxi you to school, you were on your own, hitch hike, buses, rides, what have you, you disappear, its your problem. I can really appreciate what they do with the community having experienced the above prior to.
