3.4 Often too little
Part 1

Slide 1 - Tekstslide

Learning outcomes
1. You know that water stress can arise from physical water shortage and economic water scarcity.
2. You understand why increasing water stress can lead to a water war.
3. You can assess a number of measures to alleviate water stress.

Slide 2 - Tekstslide

Slide 3 - Video

What could be a reason for water scarcity?

Slide 4 - Tekstslide

1. Climate warming: more drought
2. Population growth: more water consumption per person
(especially in rich countries)

Slide 5 - Tekstslide

Water stress
All problems that arise due to shortage of clean water.


This can lead to conflicts.

Slide 6 - Tekstslide

Why is there "stress" in North-Africa and China?

Slide 7 - Tekstslide

water stress
physical water shortage
Too little water in an area to meet the needs of residents without disrupting nature.


economic water shortage
Too little invested in an area to bring water to the area.

Slide 8 - Tekstslide

Kan er door waterstress een wateroolog ontstaan?

Could water scarcity cause a water war?

Slide 9 - Tekstslide

Water war
Armed conflict between two countries involving water.

Cause:
1. Shortage of drinking water
2. Shortage of irrigation water

How can you safe water?

1. Hold on to what you have.
2. Use less.

Slide 15 - Tekstslide



Think of three advantages of dams and three disadvantages of dams

Slide 16 - Tekstslide

You can retain water behind a dam.
Concrete or earthen wall in a river behind which the water is held.

Advantages of dam:


1. Regulate water level downstream.
2. Generate electricity.
3. Supply of drinking and irrigation water.

Slide 17 - Tekstslide

Disadvantages of dam:


1. Forced relocation of residents.
2. Reservoir silts up after a while. As a result, it is no longer a real river in the long term.
3. Breakthrough by earthquake, wall of water towards inhabited world.
4. Unfair distribution of water.

Slide 18 - Tekstslide

Use less water:
1. Use better irrigation techniques (drip irrigation)
2. Encourage households and businessess to use less and reuse more.
