An Assessment of the Impact of Sand Mining: Unguja, Zanzibar, Tanzania
In mainland Tanzania, in comparison to Zanzibar, sand mining is done mainly along the coast and in river beds. This does a great deal of damage because it destabilizes the river banks and may collapse any bridges along them. On the contrary, mining in Zanzibar is generally done on the coastal beaches or in the hinterland areas that are richer in available sand.
