- Big Dry
- Effects
- Enviromental
- Grassland turned to shrub land
- energy from hydroelectricity decreased
- Australia relied on fossil fuels, more pollution
- loss of vegitation
- loss of wildlife and plant biodiversity
- soil erosion
- the Murry Darling river basin ran dry
- Enviromental
- causes
- environmental
- el nino phenomenon
- A change in sea surface temperatures in the tropical eastern Pacific ocean
- climate change intensified the climate
- el nino phenomenon
- human (direct)
- major water wasting
- Washing cars, filling pools and watering gardens+
- defoestation
- reduces the ssurface area for leaves to catch raindrops and precipiates back to clouds
- water goes to the soil, saturated

- environmental
- reponses
- recycling water (using the water more than once
- government encouraged reduced water usage
- 4 minute showers
- desalination plant built in Sydney
- national government gave 1.7 million dollars to farmers every week
- strict water regulations
- free counselling
- environmental scientists did water trading, calculating how much water could be used by each state
- local government made water management plans
- fines if broken
- more efficient irrigation plan set up
- better drought plans for future droughts
- however many states did not do enough and suicide rates in farmers were high as a result
- Effects
- Social
- rural suicide rates increased
- people in rural areas moved to cities, putting strain on cities
- Less children in school (rural) as need to help on farms
