Important:
Have another look at the texts on Egypt and Spain and then try the exercises below.
1. Irrigation systems
Agriculture in Egypt is restricted to the fertile lands of the Nile valley and the Nile delta. In these areas the agricultural land has to be irrigated almost permanently. In most cases, flood water from the Nile river is simply sprayed on to the fields and left to infiltrate into the soil.
Crop irrigation is also very important in Spain. Here agricultural land is generally irrigated using the drip-irrigation method. Water is delivered directly to the plants, drip by drip, through special nozzles.
Exercise:
Search the internet for pictures of drip-irrigation.
Compare these two sorts of irrigation and carefully consider the pros and cons of each method.
Which technique suits each country the best?
