2
What is the connection between consumerism and water consumption?
No impact on consumption
Consumerism affects consumption in developing nations
High consumerism leads to higher consumption due to manufacturing needs
Consumerism has minor impact compared to population growth
3
What is the primary ecological function of natural wetlands?
Habitat for species
Decreasing groundwater levels
Reducing freshwater supply
Water purification and recharge
4
Which of the following is NOT a strategy for domestic water conservation?
Water metering
Grey-water recycling
Drought-resistant crops
Low-flush toilets
5
Which of the following is NOT a factor that significantly influences the availability of freshwater?
Population growth
Water management systems
Geographic conditions
Cultural attitudes to water pollution
6
What is the primary purpose of the Nile Basin Initiative?

Establish a dam
Implement water pricing mechanisms
Resolve political conflict
7
What is the purpose of the "purple pipe" systems in Australian cities?

Physical = demand exceeds supply, economic = unaffordable water
12
What is a defining feature of tiered water pricing systems?
Industrial use = cheaper water
Equal price regardless of usage
Higher usage = higher price
Exclusive to developing countries
13
What is the primary reason for water scarcity in some parts of Australia?
Lack of infrastructure investment
Inefficient irrigation techniques
Over-extraction of groundwater
Arid climate and variable rainfall
14
Which strategy for increasing freshwater supply involves extracting freshwater from saline water?
