Question 1 Report
Fig. 1 shows a hillside above a settlement in northern Pakistan after a period of intense monsoon rainfall. A local disaster-management group is deciding whether to plant native trees, improve drainage and restrict house building on the steepest land. Climate change may increase the frequency of severe rainstorms.
(a) Identify the hazard shown in Fig. 1. [1]
(b) Describe two ways vegetation can make slopes more stable. [2]
(c) Explain one reason why restricting development on steep slopes can be difficult. [3]
Answer Details
(a) Landslide / mass movement [1] (b) Any two: roots bind soil particles [1]; vegetation intercepts rainfall [1]; plants increase water uptake [1]; ground cover reduces erosion by run-off [1]. (c) Any three: flat safe land may be scarce [1]; families may not be able to afford housing elsewhere [1]; people may already own land on slopes [1]; enforcement and planning control may be weak [1]; sites may be near jobs or roads [1].
