Important:
To do the following exercises you should have read the two texts about the case studies (case study Egypt and case study Spain).
1. Irrigation systems
As you know the agriculture in Egypt is restricted to the fertile lands of the Nile valley and the Nile delta.
There the agricultural land has to be irrigated almost permanently. Therefore the regularly occurring flood water of the Nile was stacked up on the fields without control in former times.
On the opposite some parts of the agricultural land in Spain is irrigated by the so-called drip-irrigation, a special form of localized irrigation. That means that the water is given drip by drip into the area of the plants through special nozzles.
Exercise:
Search the internet for pictures of drip-irrigation.
Then compare those two sorts of irrigation and consider carefully the pros and cons.
Which technique is the best for the situation in the respective countries?
