3.9: You

• Learn about water stress, what the causes are and how people in drier climates increase the carrying capacity
• Extend your thinking on fair water use
• Calculate your own water footprint
• Finish the exercises of 3.9

In which world region is "water stress" the largest issue

1. North America
2. Europe
3. Middle East
4. Oceania

Water stress: more demand for water than supply

What are causes of water stress?

Economic water scarcity: there is no infrastructure / money to make the water available to you

Physical water scarcity: there is a flat out lack of enough water

Why is the water footprint of people in the meditteranean countries relatively high?

1. Little useful precipitation
2. A lot of inhabitants
3. High wealth

Useful precipitation

= precipitation - evaporation

-> the rain/snow/hail which does not directly evaporate can contribute to plant growth, groundwater recharge etc.

Drip irrigation uses less water than sprinkler irrigation

1. True
2. False

Enough water for everybody

1. Decrease demand - example?
2. Increase supply (more clean fresh water) - example?
3. Using virtual water in a logical responsible way - example?

Welvaart   || Economisch watertekort || Virtueel water

Voldoende energie voor Iedereen

Toenemende welvaart:
-> Voedsel, water
--> ENERGIE

Minder fossiele brandstoffen

1. Kernenergie
2. Groene stroom/energie
3. Energiebesparing.
