In the latest episode of The Perennial Plate, series creators Daniel Klein and Mirra Fine travel to East Asia, where urban farming is beginning to take hold on empty rooftops. The clip introduces us to Osbert Lam at City Farm in Hong Kong and Guichun Zhang in Beijing, each of whom have created rooftop garden oases in their respective cities. In both cases, it seems like the motives behind their gardens have less to do with sustainability or locavorism than the simple delight of growing food. As Lam says, "it's relaxing hobby, growing something. It's like a tranquilizer for city people." Our Gardens NYC subjects would agree.
