The document summarizes research on rooftop farming in Hong Kong. The researchers evaluated rooftop farms as a potential source of local agriculture in Hong Kong, where less than 5% of food is locally grown. They studied 6 case studies of existing rooftop farms, including farms at City University of Hong Kong, Feeding HK, Bank of America Tower, and Very MK Rooftop Farm. The Bank of America Tower farm was a corporate social responsibility initiative managed by Jones Lang LaSalle that partners with community organizations. The researchers aimed to inform people about the benefits and challenges of rooftop farming as a way to increase local food sources in the dense urban environment of Hong Kong.
