Questions and Answers
Which factor does NOT directly contribute to increased water demand over time?
Which factor does NOT directly contribute to increased water demand over time?
- Sustainable water use practices by the population. (correct)
- Population growth and changing lifestyles.
- Increased agricultural activity and manufacturing.
- Deforestation leading to reduced water retention.
How does consumerism typically influence the demand for water?
How does consumerism typically influence the demand for water?
- It promotes water conservation through efficient product design.
- It leads to a decrease in water usage due to increased awareness.
- It increases water usage due to the water needed for goods production. (correct)
- It has no significant impact on overall water demand.
Why does population increase affect water demand differently across various regions??
Why does population increase affect water demand differently across various regions??
- Because all regions have equal access to water resources.
- Because economic development equally offsets population impacts.
- Because water conservation efforts are uniform globally.
- Because population growth rates vary geographically. (correct)

Study Notes
- How much water is provided determines water supply.
- How much water is needed determines water demand.
- Water security is defined as the capacity of a population to maintain and protect sustainable access to adequate quantities of acceptable quality water.
- Water footprint is the amount of water used daily at home, school, or work.
Water Demand - Changes over Time
- Population increase affects water demand over time.
- Changing lifestyles affect water demand over time.
- Unsustainable water use affects water demand over time.
- The demand increases for agriculture, manufacturing, and electricity.
- Increased demand due to domestic, industrial, and agricultural use.
- Consumerism: The richer you are, the more you buy, the more water is used in production.
- Climate change affects water demand over time.
Water Demand - Changes over Space
- Population Increases happen faster in certain areas (e.g., India, Africa, China.)
- Some countries undergoing faster economic growth impact area.
What happens when demand for water exceeds supply?
- Abstraction is when something is removed.
- Water is abstracted from rivers, aquifers (groundwater), and reservoirs (man-made water stores).
- Over-abstraction occurs when taking too much water (more quickly than it can be replenished).
Impacts in a MIC - River Yangtze, China
- Social impact: Not enough drinking water.
- Economic impact: Water prices will drop.
- Environmental impact: Crops die due to lack of water.
- Environmental impact: Loss of species and wetlands.
- Economic impact: Reduction in fish species, affecting the fish feed industry.
- Social Impact: Water sources increase in salinity to undrinkable levels which reduces supply and causes saltwater intrusion due to overdrawing.
Impacts in a HIC - High Plains Aquifer, USA
- Economic Impact: Water shortages leading to more expensive alternatives.
- Regions dependent primarily on agriculture could go out of business.
- Social Impact: Wells can dry up, leading to water shortage
Water transfer schemes
- Move water from surplus areas to areas of demand.
- Kielder Water is a local water transfer scheme.
- Water is trapped behind a dam in Northwest Northumberland.
- Transferred by pipe and rivers to supply major settlements along the northeast coast (e.g., Newcastle and Middlesbrough).
