South Central Farm
"Since 1992, the 14 acres of property located at 41st and Alameda Streets in Los Angeles have been used as a community garden or farm. The land has been divided into 360 plots and is believed to be one of the largest urban gardens in the country. ... The families using the plots are low‑income and depend heavily upon the food they grow to feed themselves. In addition to growing food for themselves, the people involved with the community garden hold Farmers' Markets, festivals and other cultural events for the public at large. " -- South Central Farmers website
Unfortunately, the city has sold the land to a developer who has evicted the tenants and plans to replace the gardens with warehouses, replacing this unique green space with the same thing that is in 99% of the rest of the area. Friday is the deadline for the South Central Farmers to raise alot of money (a million dollars I think), after which they will be forcibly removed from the premises.
