Water

Often too little

Learning goals:

- You know that water stress can be caused by physical water shortage and economic water scarcity.

- You understand why increasing water stress could lead to a water war.

- You can assess a number of measures to eliminate water shortages.

Which country has too little water?

1. The Netherlands
2. Mexico
3. Mali
4. Russia

Stress from too little water?

- Big problem in developing countries, and dry regions

- Too little water leads to a water stress

When water becomes scarce in a country, usually the people get stressed and they could go to war because of it.

There are 2 kinds of water shortages:

- Physical water shortage -> Having no water at all.

- Economic water scarcity -> No available drinking water.

I already stated that some countries go to war because of water. What are the main reasons for that?

Shortage of drinking water and shortage of irrigation water

How can we save
water?

Ways to save water:

- Lots of water is being unused. People need to retain the water behind large water dams. This way people can use it in times of need

- People need to use less water in their daily lives. This way we can distribute water more to places where people need water.

- Use dripping irrigation. With this method, less water will evaporate and it is more efficiently.
