There is a growing tendency of new farmers joining the field, and they tend to prefer to practice farming as leisure or recreational activities. Aiming to facilitate the knowledge acquisition for these new farmers, and to keep arousing the interests of more citizens joining agriculture, a new interactive platform for Hong Kong agriculture (https://agropedia.hk), which hopefully can also be developed as a sustainable platform was constructed. Various food plants which were inhibited by the pests in different seasons were authenticated and well documented. 3D images of common pests have been generated and shared with general public through a newly developed mobile Apps and website.
