Our partner EBF was in Barcelona at the Smart City Congress at the end of november! They participated in the urban farming session and it was filmed.
Their session starts at 58:50, Marie-Angélique is talking at 1:13:40, Xavier at 1:21:30 and I start at 1:30:30. Afterwards there is some discussion! It was a really nice panel and interesting stuff (also the first three talks were very informative!).
