Question

Write briefly about the role of forest in soil and water conservation

Answer 1

Answer:

Forests also prevent soil erosion and keep soil pollution in check. Deforestation, in fact, leads to soil erosion on a large scale since the topsoil comes loose. Forests also play an important part in the water cycle and control moisture levels of our ecosystem.

Trees and ground vegetation in forest ecosystems slow water movement and help stabilize soil. Prevention or reduction of soil erosion helps reduce sedimentation type pollution in streams, rivers and lakes.

Answer 2

Forests have a good impact on peak flow decrease, landslide risk reduction, soil preservation, and high levels of water purity.

Explanation:

• Forests protect soil from wind and water erosion both directly and indirectly. Wind erosion is uncommon in wooded areas, which are shielded from the elements by the forest canopy, tree roots, and litter on the forest floor.
• Forests also help to conserve rainwater that is already in the soil by limiting evaporation (by blocking sunlight from reaching the soil surface, which causes evaporation).  
• Forests also help to avoid soil erosion and pollution. Because the topsoil becomes loose as a result of deforestation, it causes widespread soil erosion.
• Forests also play a vital role in the water cycle, regulating the amount of moisture in our ecosystem.
