GGRB05H3 Lecture Notes - Lecture 6: Sewage Treatment, Natural Disaster, Ecological Footprint
Document Summary
Pros and cons of cities as green economies: pros: Density of cities make infrastructure like mass transit much more possible. People often take up less land per capita. Dense housing structures take less energy to heat and cool: cons: Food and goods often have to be shipped from farther away. Cities can be places that encourage consumption oriented lifestyles. Cumulative urban decisions can make environmental problems much worse (car use) The acute concentration of polluting activities in cities can have a major impact on surrounding areas (water pollution, air pollution) North, environmental priorities might reflect the need to increase green spaces or improve the quality of local wetlands: brown agendas are those that have the most pressing impact on the urban poor. In some cities in the south meanwhile, are grappling with serious issues of making the water drinkable, instituting sewage treatment services etc. , urban drainage systems etc.
