Question

Deforestation causes soil erosion ?

Answer 1

When a forest is cut down, nothing is left to protect the soil. Wind blows it away. Rain quickly washes away what healthy soil was there, and compacts the rest. A compacted soil absorbs much less water, making it run off more quickly. No spongy soil, nor plant roots to absorb the water mean that rain forms gullies and washouts. Often times land that is forested (as opposed to agricultural land) is found on steep hillsides; once these forests are cut down, the erosive effects are much worse than on flat land. Erosion and rainfall in such places can cause large mudslides beyond just washouts.

On a local scale, this can cause serious land degradation. On a landscape scale (as with slash and burn agriculture and in most places where industrial logging is common place), it is catastrophic for soil integrity and surface water quality. Once cut down, a piece of land might take 100 years or more to regain it’s former forest cover and capacity to hold water, and rivers without rehabilitation efforts might take decades or more to recover (if they do) their former habitat and quality.

Answer 2

Yes deforestation causes soil erosion roots of trees hold soil tightly and prevent the soil from erosion if we cut trees the roots leave the soil and that's why the soil will Erode
