2 NAMED EXAMPLES: waste disposal

Curitiba

• 70% of waste is recycled

• Green exchange programme - residents exchange recyclable waste for food or bus passes

Cairo - Zabbaleen

• community that collects waste door to door, make profit by feeding it to pigs which they sell and selling recyclables like bottles

• informal economy

why is waste management often more successful in MICs and LICs

poverty forces people to value waste more, sorting and selling as much as they can

EXAMPLE: urban air pollution PROBLEMS

Mexico city

• population boom + rising income → more people more cars + congestion

• †surrounded by mountains → harder for wind to disperse pollutants
