Human activities leading to coastal degradation
Delphine Digout, UNEP/GRID-Arendal
Physical alteration and destruction of habitats are now considered one of the most important threats to coastal [and marine] areas. This graphic shows the extent to which twelve different human activities cause environmental degradation in estuaries, inter-tidal wetlands and the open ocean. The activities include the drainage of coastal ecosystems; the construction of dykes, dams and seawalls and the mining of wetlands.
