Answer
Some activities that could prevent and reverse desertification are:
- The growth of vegetation on the wind-ward slopes can prevent erosion by wind. It can help stabilize soil, prevent erosion, and promote groundwater recharge.
- Long-rooted trees and sand-holding grasses can be planted to halt the advance of the dunes in order to prevent the fertile land from being devastated.
- Rainwater harvesting can help replenish groundwater reserves and improve soil moisture, reducing the risk of desertification.
- Overgrazing by livestock can contribute to desertification, so measures such as rotational grazing, herd management, and fencing can help prevent this.
- Measures such as contour plowing, terracing, and cover cropping can help prevent soil erosion and improve soil fertility, reducing the risk of desertification.
- Effective policy and planning can help prevent desertification by promoting sustainable land use practices, protecting natural resources, and encouraging community participation.
