1

What stage of economic development is Australia at?

AC
In 2014 it was the 2nd highest on the UN's HDI and had a per capita gross national income of US$41,500

2

Environmental Impacts and Threats: Kakadu National Park

Saltwater intrusion along estuaries has damaged freshwater ecosystems in sensitive areas

3

Environmental Impacts and Threats: Great Barrier Reed

Damaged by rising sea levels, ocean acidification, and bleaching (high temps stress algae in coral so colour is lost and coral dies).
Nutrients and pesticides flow into the sea from coastal farms and cities in Queensland, polluting the water.
The Climate Council said the reef's temperatures in early 2016 were the hottest since records began in 1900.

4

Environmental Impacts and Threats: Coastal Squeeze

Delicate sea grass and salt marsh ecosystems are trapped between advancing shorelines and sea walls, so are exposed to wave action and erosion.

5

Socio-Economic Impacts and Threats: Cost

Natural distasters expected to cost the economy US$4.5 billion each year. This is expected to double by 2030.

6

Socio-Economic Impacts and Threats: Bush Fires

Loss of life
Damage to property and business
2009 bushfires in Victoria killed 173 people and destroyed over 2000 homes

7

Socio-Economic Impacts and Threats: Coastal Flooding and Rising Sea Levels

Tropical Cyclones have devastated Queensland and New South Wales in the last 15 years. Cyclone Yasi in 2011 reduced Queensland's GDP by US$4 billion
120 ports, 5 power stations, 258 police, fire, and ambulance services, and 45 water and waste facilities are within 200m of the coast
250,000 homes are at risk
If sea level rises were ignored, by 2050 the global impact of coastal flooding would cost $US1 trillion each year - the size of the Australian economy.

8

Socio-Economic Impacts and Threats: Human Health

2009 heatwaves in the south east led to a sharp increase in heat-related deaths in Melbourne and Adelaide. Temperatures reached 45.1 degrees Celcius

9

Socio-Economic Impacts and Threats: Murray-Darling Basin

Australia's most important agricultural region
Millennium drought (1996-2010) was the longest on record and led to a steep decline in crop yields leading to expensive government relief packages

10

Socio-Economic Impacts and Threats: Drought and Rainfall Patterns

Driest inhabited continent
Since the mid 1990s rainfall in the south east has dropped by 15%
Hotter temperatures = more evaporation = intensified and prolonged drought
Affects employment, tourism, water supple, and ecosystems

11

Socio-Economic Impacts and Threats: Food Supply

Avaerage yields of mungbeans reduced from 1-1.5 tonnes per hectare to 0.1-0.5 tonnes per hectare.
Increases in population and wealth will lift global demand for food by 70% by 2050, but crop yields are decreasing

12

Mitigation: CO2 emissions increased by what between 1990 and 2010?

30%

13

Mitigation: CO2 emissions are how high?

Among highest in the world per capita

14

Mitigation: targets to increase what by 2020?

Renewable energy

15

Mitigation: Kyoto/Copenhagen: in 2013 agreed to what reduction in CO2 at Copenhagen by 2020?

5-25% (based on 2000 emissions)
This was well below other ACs

16

Mitigation: What is linked to the EU?

Cap-and-Trade scheme

17

Mitigation: Kyoto/Copenhagen: When was Kyoto endorsed?

2007

18

Mitigation: Paris 2015 (not effective): based on current growth Australia will be how much above Paris targets by 2030?

30%

19

When did CO2 emissions peak?

2017
2015-17 were in the hottest 6 years on record

20

Adaptation - what will be upgraded?

Early warning and disaster response

21

Adaptation - Coastal and River Flooding - prevention with what?

Sea walls, flood gates, dams

22

Adaptation - Land Use Zoning - What will happen in areas of high flood risk?

Relocate buildings and have strict planning laws to prevent development

23

Adaptation - Water supply - $9 billion investment programme to do what?

Develop new resources, use existing resources more efficiently, and protect wetland ecosystems

24

Adaptation - Water supply - Wyangala Dam (New South Wales)

$650m upgrade

25

Adaptation - Water supply - Dunyowan Dam (near Tamworth)

$480m new dam

26

Adaptation - Agriculture

Develop crop strains suited to hot and dry conditions
Plant wheat earlier to align with optimal window for flowering
