Strand 7: Urban Environmental Issues Flashcards
(9 cards)
Why is waste an issue in urban areas?
Waste is an issue because there’s a limited amount of space in which to dispose waste so it can become an environmental problem.
Impacts of increased waste
- loss of biodiversity
- pollution
- raised health issues (respiratory, skin & other diseases)
Landfill v. incineration
Landfill: Dutch government approach to waste was to reduce their reliance in landfill, only landfill in an environmentally acceptable way, more space needed for landfill.
Incineration: AED in Amsterdam an incineration plant capable of producing 1 million MWH of electricity annually (W2E: waste to energy), by burning waste to make energy this has 632 kilotons less space than landfill
What is dereliction?
Loss of industry or productivity of a land leaving it abandoned, unused or unoccupied.
Dealing with dereliction- developing brownfield sites to make it more appealing to live in.
Issues with air pollution & management of the issue.
Issues!: health problems is the major issue (strokes, heart problems etc..) but also climate issues (fog, smog over cities)
Management: encourage sustainability, keep chimneys at a certain height, ban the use of polluting vehicles or use alternative transport. Try walking or cycling.
Water pollution
Causes- industrial, agricultural, & urban runoff p. Global warming, deforestation, traffic (fuel spillage).
Issues- diseases with health, poor drinking water/lack of clean water. Dumping!
Types of pollution- chemical, groundwater, microbiological, nutrient, oxygen depletion & surface water & thermal.
Management of the issue- water treatment facilities, water usage, use of grey water, keeping taps on for limited time.
Municipal..
Belonging to a town/city
Municipal waste - everyday items disgarded by the public collected by road sweepers/public bin men…
Municipal solid waste - urban waste incl.solid domestic waste & commercial waste
*Uk urban waste grows by approx 3% per year - an unsustainable amount!
Waste increase over time
1980: 1.73billion people: waste at 39%
2015: 3.968billion people: waste at 54%
2025 (expected): 6.419billion people: waste at 66%
Waste streams
