Question 1 Report
A geography class studied the effects of a long hot desert drought on a village beside the seasonal Draa River in Morocco. Fig. 1 shows the field observation route from a dry reservoir to grazing land. Table 1 gives rainfall and water-use figures gathered from the village council. The study helps residents consider how water can be used more sustainably during years when rainfall is unreliable.
| Year | Annual rainfall (mm) | Reservoir volume in July (million m3) | Water used for irrigation (million m3) |
|---|---|---|---|
| 2021 | 168 | 9.6 | 6.1 |
| 2022 | 104 | 5.8 | 5.9 |
| 2023 | 71 | 2.7 | 4.8 |
(a) Which year had the lowest reservoir volume, and state the volume. [2]
(b) Outline two impacts of drought on people living in this hot desert landscape. [2]
(c) Draw an annotated sketch showing four methods the village could use to reduce water stress. [4]
Answer Details
(a) 2023 [1]; 2.7 million m3 [1]. [2] (b) Any two: crop yields fall / livestock die [1]; water must be collected from farther away [1]; food prices rise [1]; migration for work may increase [1]. [2] (c) Four annotated methods, one mark each: drip irrigation delivering water to roots [1]; repair pipes to reduce leakage [1]; collect rainwater from roofs into tanks [1]; grow drought-resistant crops [1]; reuse treated wastewater [1]; cover canals / reservoirs to reduce evaporation [1].
