Lesson details
Key learning points
- 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.
Keywords
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 misconception
In LICs and NEEs there is a general lack of safe drinking water.
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.
