Abstract
Urban populations benefit greatly from the ecosystem services provided by urban green and blue spaces. While the equity of provision of and access to urban green and blue spaces has been widely explored, research on equity of ecosystem service provision is relatively scant. Using household level data, our study aims to assess the supply equity of five regulatory ecosystem services in Singapore. We employed linear mixed-effects models and Hot Spot Analysis to analyze their distributional equity across individual households of various demographic characteristics (horizontal inequality), and calculated Gini coefficient for the distribution of PM10 removal service among households categorised into demographic subgroups (vertical inequality). Our results show little evidence of inequitable ecosystem service provision among Singapore's diverse socio-demographic groups. This can be attributed to the early integration of environmental management strategies and meticulous socio-economic desegregation efforts into urban development plans, which maximised provision and maintenance of urban green spaces to all residents.
