Symposium Outline

JPFA International Symposium on Plant FactoryJPFA International Symposium on Plant Factory

■JPFA International Symposium on Plant Factory
Toward a sustainable future, we aim for open discussion and international co-creation on the issues such as utilization, roles, technological challenges, and direction of plant factories with artificial lighting (PFALs) that possess diverse purposes and applications. Additionally, there is potential for the use of PFALs in social activities as part of the global ecosystem and in creating varied and flexible food and plant production systems. These topics will be covered through open discussions and international collaboration at smart city Kashiwa-no-ha, with a view to achieving “staying healthy simply by living.”
