Study of Sand Mining and Related Environmental Problems

that instream mining is the prevalent type of sand mining in the study area and accounts for about 51% of the sand mining operations along Nzhelele River whilst flood plain mining only constitute 44%. A very small percentage (5%) of the operations employ both instream and floodplain mining in the study area.
