Answer Details

To check desertification in the arid zones, **drought-resistant** trees should be planted. Drought-resistant trees are those that have adapted to survive in arid conditions with limited water availability. These trees have evolved various mechanisms to cope with water scarcity, such as deep root systems that can access water from deep within the ground, waxy or hairy leaves that reduce water loss through evaporation, or the ability to store water in their tissues. By planting drought-resistant trees in arid zones, we can help to stabilize the soil and prevent erosion. These trees can provide shade, decreasing soil temperatures and reducing evaporation. Their deep root systems also help to bind the soil together, preventing wind erosion. Furthermore, the presence of trees can improve soil fertility as their leaves fall and decompose, providing organic matter and nutrients. Therefore, planting drought-resistant trees in arid zones is a simple and effective way to combat desertification. These tree species have the ability to survive and thrive in water-scarce environments, making them the most suitable option for addressing desertification.
