Worked Solution & Example Answer:Name the area shaded orange marked A to B on the map above - Junior Cycle Geography - Question i - 2019
Step 1
Step 2
Explain one human cause of desertification.
Answer
One significant human cause of desertification is deforestation. This occurs when large areas of trees are cut down for agriculture, logging, or urban development. The removal of trees diminishes the land's ability to retain moisture, leading to soil degradation. As the vegetation cover decreases, the soil becomes more vulnerable to erosion by wind and water, exacerbating desertification.
Step 3
Describe two ways to limit the spread of deserts in a region.
Answer
-
Afforestation: This involves planting trees in deforested areas or barren land, which helps to restore vegetation cover. Trees improve soil quality, increase moisture retention, and reduce erosion, making the land less susceptible to desertification.
-
Irrigation Schemes: Implementing effective irrigation systems allows for the controlled distribution of water to crops, reducing reliance on rainfall. This method supports agriculture in arid regions and helps maintain soil fertility, therefore limiting desert expansion.
