One example from Los Angeles:

A permanent farmers’ market hub in Hollywood that makes the farm experience visible to urban residents with vending, greenhouses, social programs and educational facilities.
“The New City Center of Urban Farming (NCCUF) is the new information and food hub for the Los Angeles neighborhoods. This NCCUF and its four elements of demonstrative production (greenhouse), distribution (farmers market), processing (data center) and education (information center) centered around farming, both crops and data will feeding the new idea of rural and healthy living into metropolitan lifestyles.”
