The fast and steady economic growth and social changes in recent years in Cambodia have brought rapid expansion and restructuring to its cities. These phenomena have brought numerous challenges including threats to urban green spaces (UGS’s). This study addresses problems of UGS’s by investigating the knowledge and perceptions of young residents of Phnom Penh (YRPPs) toward UGS’s in relation to the following: (1) basic knowledge of YRPPs on ecological services (KES) of UGS’s; (2) perceptions of YRPPs on the current state of UGS’s (PUGS’s) in Phnom Penh; (3) demand of YRPPs for UGS’s in the city (DUGS); and (4) associations between KES, PUGS’s, social profiles (SoPs), and DUGS.
