| Summary≠ | Urban metabolism analysis treats a city as a living organism that ingests materials, water, energy and food and excretes wastes, emissions and outflows, accounting for these flows to understand and improve a city's resource use. Drawing on the biological metaphor that Abel Wolman introduced in his 1965 'The metabolism of cities', the method draws a system boundary around the urban area and constructs a mass and energy balance of everything entering, accumulating in, and leaving it. The resulting per-capita flows and efficiency indicators expose how resource-intensive a city is and where interventions could close material loops. | Urban green space analysis measures how much vegetation and parkland a city provides and how fairly residents can reach it, combining remote-sensing greenness, per-capita provision, and accessibility into evidence for planning and public health. Satellite vegetation indices such as NDVI map greenness pixel by pixel; per-capita ratios benchmark provision against standards; and gravity or threshold accessibility measures show who lives within reach of a park. As Wolch, Byrne and Newell argued, the analysis is inseparable from environmental justice — green space is unevenly distributed, and its provision must be designed to be 'just green enough' without driving displacement. |
