“…Green spaces encompassed both urban and rural environments, and most studies described green spaces as urban parks [57, 62, 65, 69, 74, 82, 85, 88, 91], natural environments [63, 68, 70, 72, 86] urban forests [53, 62, 78, 81] or as gardens [64, 73, 74, 78]. Other areas or features of green spaces were used less often, such as farms [53, 66, 78], micro-features of green spaces [57, 74], national parks or reserves [60, 89], a game reserve [61], urban stream corridor [55], playground [72], meadows [54], bog [89], or neighbourhood greenness [77]. Similarly, blue spaces also covered urban and rural environments and were characterised by the terms: sea [56, 90], blue environments [70, 86], river [53], fountain/ seawall [74], coastal area [59], loch [61], wetlands [87], wilderness [90], ocean and beaches [83].…”
