Document Summary
Vortex city: eco-appropriation parts of ecosystem that city uses (e. g. seafood from ocean, ecosystem services, not everyone can be a net importer of ecosystem services. Great need for sanitary city: 2. Easiest to measure and understand in the regional hinterland (rather than globally: 3. Urbanized: 3% (census data + lights at night) Built-up area: . 5% (satellite image analysis remote sensing) Impervious surface area: . 4% (high resolution remote sensing) Global view of urbanized areas: 20% of urban places w/pop <500k, coastal land is 10% urbanized, 65% of city dwellers live in coastal cities. Us view of urbanized: again, a lot of coastal. Fewer wetlands to provide clean h20/natural flood control. Loss of air pollution filtering; creation of dust. Loss of carbon sequestration in forests or other land cover types. Response: sanitary city to city beautiful: sanitary city. Sanitary engineering; major infrastructure projects: city beautiful. Photos as documentary evidence, but some class bias in remedies used.
