As we know that trees have long roots spread into soil to a larger distance. Soil erosion occurs when the soil takes the surface land with it. So if the trees are present there they will keep the soil firm and stop it from sliding. Therefore the erosion can probably occur in the land where there are no trees.
In "Hydroelectricity" we build dam in order to produce electrical energy by rotating our huge turbines. As Dam separates the division of water into two parts, It can store/prevent flooding and protect community
In short, Your Answer would be "Hydroelectric Power"
Hope this helps!
