Fig. 2: Overview of UGS use in studied cities.
From: Global disparities in urban green space use during the COVID-19 pandemic from a systematic review
a, Changes from before to during first lockdowns. b, Changes from before to after first lockdowns (indicated by respective virus icons). Data points are color-coded by reported outcomes (n = 237) with each colored point indicating one studied city. Points in the bottom left of a and b (Global studies) report results for multiple locations together. Increasing symbol size and color saturation indicate increasing study validity score based on ratings from the critical appraisal of quantitative methods. Europe is magnified due to the high study density; no studies were found in North and West Africa, which is therefore covered. Data points arranged on circles around small black dots show studied cities in overlapping locations at the depicted scale. Basemap from Natural Earth (https://www.naturalearthdata.com).
