For the geography topic, Issues in Australian Environments, does anyone have any notes either on 'Waste Managment' or 'Coastal Management'. It must cover the following:
- Nature
- Impacts
- Responses by individuals, groups and governments
- Geographical processes relevant
- Perceptions of different groups
- Decision-making processes
- Management of the issue
all ive got for waste management is
- 4kg of waste per person
- Lack of landfill in Sydney
- We can: recycle, buy in bulk, limit packaging.
and coastal management
Coastal Management is about managing all development along the coast so that it is sustainable.
Key impacts humans have on coastal areas:
Housing and Development
Ports and Marinas
Stormwater Runoff and Pollution
Sand Mining
Recreation and Tourism
Key processes shaping coastal environments:
Estuary – where the river meets the ocean
Groyne – wall designed to trap sand
--> stop erosion
Dunes – an accumulation of sand
Erosion – wearing away of land due to wind + waves
Deposition – distribution of sand along the coast --> dunes, spits, bars
Waves – constructive + destructive
Currents – Longshore drift + rips
Management strategies
Groyne- artificial structure to trap sand from longshore drift
Seawall – parallel to coastline separate land from sea
Beach nourishment – artificial placement of sand
--> spread naturally
Buy back – govt. buys back properties to restore natural beach
hope this helps..
