This study investigates global variations in urban tree and nontree vegetation cover from 2000 to 2020, analyzing their drivers and impacts on population exposure. Using satellite data and socioeconomic factors, the researchers found that approximately 90% of cities experienced increased tree cover, while 49% showed increased nontree vegetation. However, human exposure to urban tree vegetation significantly declined in the Global South, widening the North-South disparity. The study highlights persistent inequalities in greenspace access and calls for equitable strategies to reduce these disparities.
