Other impacts are hard to directly link to sand mining since rivers are affected by so many different factors, including dams, but it is clear that by sucking too much sediment out of the world's rivers, unsustainable sand mining will contribute to bank erosion and shrinking, sinking deltas – with the loss of agriculture land, houses and ...

River sand mining is widespread in most of the developing and developed countries. Of the different types of fluvial systems, small rivers (catchment area <10,000 km 2) are the worst affected due to indiscriminate sand mining than large rivers as the area available for dissipation of negative externalities is low in small river basins.This chapter …
