Afforestation means planting trees. As we know, the roots of the trees help to hold the soil layer firmly,it is evident that it helps not to make the soil loose and prevents erosion. Thus, by planting more and more trees, the top layer of the soil becomes less prone to erosion by wind, water or anything likely. Thus,it prevents erosion and helps in soil conservation.
