Global sediment loads
Philippe Rekacewicz, UNEP/GRID-Arendal
Asia exhibits the largest runoff volumes and, therefore, the highest levels of sediment discharge. This graphic shows the amounts of suspended sediments discharged, in millions of tonnes per year, in the major regions of the world. The levels of suspended sediments are increased by soil erosion and land degradation, and may affect aquatic ecosystems negatively.
