Design is a means to satisfy social demands, and such demands come from human desires. Only when individuals' desires fuse and grow into a collective consensus, can they be manifested and conveyed in various landscape forms as new public goods. As a public goods serving human desires and social demands, landscape design faces both challenges and opportunities preceding undergoing public crises. In this issue, LA Frontiers explores the implications of human desires on public behaviours through cross-disciplinary lenses of philosophy, social psychology, cognitive science, cultural studies, anthropology, sociology, history, etc. It would offer inspiring insights for landscape professionals to identity their role in responding to contemporary demands and those of future societies. At present, in view of the spatial isolation caused by the COVID-19 pandemic and the consequent prevalence of contactless services, the current conventional space-time narrative may be dramatically changed. The fact that both "observing" and "being observed" now become consumer goods within landscape enables landscape architects to recognise and examine people's suppressed desires and unmet needs, introspect the rationality and necessity of marginal desires, and thus, redefine the sophisticated interactions between landscape design and human desires, as well social demands.
