Fact File: The Rooibos Tea industry Rooibos, a very hardy, dry land, indigenous fynbos plant is endemic in the area – it only grows naturally in the Clanwilliam and Cederberg area of the Western Cape. Historically it is the plant the San used to make tea from. Today commercial farmers have large plantations of the teabush and a number of smaller fair-trade cooperatives have formed. Processing and packaging plants are found on the larger tea estates. The plant only grows in deep sandy soils, at altitudes of between 200 and 500 m above sea level.

(2) (b) Fill in and indicate the approximate position of the new rerouted section of the N7 on the cross section. (2) (c) (i) The dam wall will be raised by 20 m. This means the capacity of the dam will therefore increase. Draw in a horizontal line on Figure 2 to show the dam level once the wall is raised by 20 m. Note: Refer to the vertical interval provided on the cross section. (2) (ii) Explain what would happen to the areas surrounding the dam, if the wall was raised by 20 m. (2) (iii) What GIS process would have been used by the Department of Water Affairs to decide which properties must be expropriated when the dam wall is raised? (1) IEB Copyright © 2017
