Thus, comprehensive current are important for achieving sustainability. This study aims assess spatial pattern across cities bibliographic These six further supported from evidence cities. Geographical information system (GIS) techniques questionnaire surveys performed mapping perceived respondent sustainability findings showed that (i) highest PCGS was reported Dammam (5.4 m2) followed by Riyadh (1.18 m2), Jeddah (0.5 m2); (ii) most respondents use picnic (59%), mental well-being (53%), physical activities (47%), respectively; (iii) significant local climate regulation such as temperature control (78%) UHI reduction (81%), provide thermal comfort (84%), (iv) 40% do not due lack availability, accessibility, design, safety GSs. surely assist planners policy makers understand implement suggested meet satisfaction level well manage at neighborhood city
