Impacts of Land Cover Change

Question 1

Climate Change

Answer 1

long-term change in statistical distribution of weather patterns over periods to a specific region, anthropogenic being a primary cause.

Question 2

Land Cover Change

Answer 2

changes natural environments due to natural (earthquake, bushfires, erosion) and/or anthropogenic-induced causes (mining,deforestation, urbanisation)

Question 3

Biodiversity loss

Answer 3

extinction of species of fauna/flora in habitat due to natural and human factors.

Question 4

Land Cover Changes in the Swan Canning River Catchment:

Answer 4

• The arrival of Europeans - Early settlement of the area in 1942
• Deforestation along the river - 1942 - 2003
• Intensification and Expansion of agriculture - 1942 - 2003 (grazing and crop farming)
• West of River Deforestation - 2003
• Growth of Urban Settlement - 2003

Question 5

Adaption

Answer 5

alteration or adjustment in response to a changed environment

Climate change - Desalination Plants
- removal of salt and impurities from seawater to produce drinking water
-

Question 6

Mitigation

Answer 6

involves the implementation of the strategies to eliminate or minimise the severity of a hazard or similarly adverse occurrence.

• Twiggy’s Fortescue plans $10 Pilbara Wind and Solar Farm.
• Project reduce annual carbon emissions of 2.2 million tonnes by at least 1.5 million tonnes end of the decade

Question 7

LS - Social

Answer 7

Group: Local Communities
Living Streams
- living streams can have positive social impacts, provide clean water, create recreational opportunities, and enhance the aesthetic value of the area.

Oxygenation plant
Improves oxygen conditions 39-92% of the Target oxygenation zone

Question 8

LS - Environmental

Answer 8

Living streams
Living streams can improve water quality, reduce sedimentation and nutrient pollution, and increase oxygen levels. positive impacts on aquatic ecosystems and human health by reducing the incidence of waterborne diseases.

Oxygenation plant:
Address the effects but not the cause of an environmental problem

Question 9

LS - Economic

Answer 9

implementation of living streams can create job opportunities in a variety of sectors, such as construction, engineering, and maintenance. This can provide economic benefits for local communities and support regional economic development.

Expensive maintenance 200 000 - 400 000 per anum per plant

Question 10

Oxygenation plant

Answer 10

Oxygen plants are an artificial way of oxygenating an ecosystem, more specifically rivers. The process…. this is important because plants use O2 as food and is essential for their survival. the maintenance of an oxygenated water column promotes healthy ecological processes that break down organic matter and recycle nutrients.

Question 11

Living streams

Answer 11

Living streams vegetation uptake nutrients reducing eutrophication and sedimentation
Increase biodiversity plants
