Step 1
Step 2
Explain one human cause of desertification.
Answer
One significant human cause of desertification is deforestation. As populations grow, there is an increasing demand for land for agriculture and urban development. Trees are often cut down to make way for crops or buildings, which removes essential vegetation that holds the soil in place. Without tree cover, the soil becomes vulnerable to erosion and degradation.
Step 3
Describe two ways to limit the spread of deserts in a region.
Answer
-
Afforestation: Planting trees in areas that have lost vegetation can help restore ecosystems. The roots of trees stabilize the soil, improve moisture retention, and provide shade, which supports the growth of other plants.
-
Irrigation Schemes: Implementing effective irrigation systems can help maintain soil moisture in arid regions. This allows for sustainable agricultural practices, promoting the growth of crops that can thrive in dryer conditions and thus reducing the encroachment of desert areas.
