On 09/25/2010, horticulturalists Jennifer Nelkin described her work developing rooftop hydroponic greenhouse business called Gotham Greens in NYC.

Farm City Forum concluded Farm City, a three-week series of events exploring the possibilities for urban agriculture in the current reality of NYC as part of Crossing the Line: FIAF Fall Festival from 9/12 to 9/25/2010. Farm City Forum took the format of an “unconference,” a lively participant-driven series of discussions exploring how to shape the future of urban agriculture. Three Sessions, each with its own distinct approach, brought together artists, farmers, urban planners, architects, food activists, and authors. The Primary Goal of the Forum was to engage participants in a visioning process about transformative possibilities of urban agriculture as a means to generate new thinking and experimental action positively impacting a more sustainable future.
The Forum's Secondary Goal was to explore how artistic interventions transform and illuminate urban agricultural endeavors and vice versa.
