Control soil erosion by planting indigenous trees

For areas that fall directly on the flow of river, various new materials have be innovated which controls and keeps a check on soil erosion for years. But for other areas, mulch matt can be used, it uses coconut fibres and jute which can be procured locally .also instead of only focussing on indigenous trees(assuming it will take years to fully develop) we can use fast spreading shrubs.. which will grow immediately and help to resolve the immediate problem at hand.
