Urban ecology and urban political ecology
Urban ecology basics
Ecology OF cities, not IN cities. It is a new approach
Old approach is going to somewhere undisturbed and study
The study of relations of living organisms to each other and
surroundings
Ecosystem studies flows within particular ecosystems, of nutrients,
energy, waste, and the subsystems that structure those flows
Cities are a special kind of ecosystem that human have created
What is the overall structure of urban ecology?
Closed and open loops
Natural systems are stable
There is no waste in natural ecosystems
Cities are not closed loops
Cities import material from long distances
Cities export garbage and waste
Waste disposal solutions involve finding better waste sinks, not
reducing
Industrial ecology seeks to close loops, using industrial waste for other
industries
On global scale, all loops are closed
Cities extended their chain (input and output) on a global scale
Landfills are extremely toxic, they are extremely expensive to make,
recycling becomes more popular

Industrial ecology seeks to close loops, using industrial waste for other industries. on global scale, all loops are closed. cities extended their chain (input and output) on a global scale. landfills are extremely toxic, they are extremely expensive to make, recycling becomes more popular www. notesolution. com. raw material are becoming more expensive, motivation to recycle. people look for ways to close the loops. key works on urban ecology, studies cities as flows (of people, energy, goods, etc)
