Lesson Summary
You will learn to explain reasons for the increasing demand for water and factors that affect water supply.
Key Notes
- Globally, water consumption is rising.
- Water consumption is increasing due to economic development.
- Water consumption is increasing due to population increase.
- There are physical factors that affect water availability, such as climate and geology.
- Human factors affecting water availability include pollution, over-abstraction, limited infrastructure and poverty.
Vocabulary To Learn
- abstraction: the extraction of water from a water source, such as a river or aquifer
- over-abstraction: occurs when the extraction exceeds recharge by precipitation
- poverty: more than lack of income, it includes hunger and malnutrition, limited access to education and other basic services
Common Mistakes To Avoid
- In LICs and NEEs there is a general lack of safe drinking water.
3 Quick Questions (With Answers)
1. Explain this geography topic using two clear key points.
Globally, water consumption is rising. Water consumption is increasing due to economic development.
2. Define this geography term and use it in an example. 'abstraction'
the extraction of water from a water source, such as a river or aquifer.
3. Correct this common geography misunderstanding.
Mistake: In LICs and NEEs there is a general lack of safe drinking water. Correction: There is unequal access to safe drinking water in LICs and some NEEs, rather than a general lack. Investment in infrastructure often lags behind population growth. Wealthier people buy bottled water or expensive home purification technology.
