Why focus on cities in SD discourse?
~ policies aimed at achieving SD:
- greatest leverage at city-level [why?]
* rich countries: most people live in cities
* production/ consumption: mostly in cities
* high urban densities savings (materials & energy)
* local govts: immediately accountable to constituents
How cities could help achieve SD goals?
~ meet human needs in cities without depleting
environmental capital
AND
~ improve environmental quality in cities
AND
~ reduce transfer of environmental costs:
- to other people
- to other ecosystems
- into the future
Cities: five environmental actions SD goals
1. control infectious diseases
2. reduce chemical & physical hazards
3. create a high quality city environment for all
4. minimize transfer of env costs to people/ ecosystems
outside city boundary
5. ensure progress toward “sustainable consumption” of
world’s natural capital
Action 1: Control infectious diseases
~ mis-management of public health diseases
- emerging diseases
- re-emerging diseases
- why emerging and re-emerging diseases?
~ cities: advantages for control of infectious diseases
- concentration of people lower unit costs
- concentration of expertise & resources
Action 2: Reduce chemical & physical hazards
~ industrial production + road traffic hazards
- home: control indoor air pollution
- workplace: control occupational hazards
- neighbourhood: reduce risk from floods & landslides
- urban: traffic management
Action 3: Build a high quality city environment
~ provide facilities pleasant & safe environment
- sufficient: on per capita basis
- accessible: for all city dwellers
- responsive: diverse needs & priorities
~ institutional barriers
- middle- & upper-income groups
* purchase/ rent: exclusive access to env provisions
* reduced pressure for public action
Action 4: Minimize transfer of env costs to city-region
~ demand for resources & waste generation in cities
impact on ecology of city-region
- sewers & drains improve city environment
* impact of wastewater on wider region
- tall smokestacks: transfer env costs of power stations
* acid rain damages on region’s ecosystems
Action 5: Sustainable consumption: global natural capital
~ important distinction between Action 4 & Action 5
Action 5: beyond city-region & into the future
~ consumption in wealthy cities: consequences?
- imports: transfer env costs outside city-regions
- GHGs: transfer env costs into the future
~ a North-South issue [why?]
- concentration of high consumption HHs in North
- much greater historic contribution by North
Constraints on environmental actions
~ Actions 1, 2 & 3:
- whose responsibility?
- who oppose such actions?
- prospect?
Constraints on environmental actions
~ Action 4:
- whose responsibility?
- who oppose such an action?
- “environmental racism”
- institutional constraints
- prospect?
Constraints on environmental actions
~ Action 5:
- whose responsibility?
- “green consumerism”/ “eco-labelling”
- “fair trade”/ “ethical sourcing”
- who oppose such an action?
- prospect?
