Human impact in the coastal zones
Infrastructure development, intensive agricultural expansion, urbanisation and coastal development are increasing the flow of sediments and sewage into the ocean. The situation is most severe around Europe, the East coast of the United States, East of China and in Southeast Asia. These are also primary fishing grounds. Coastal zones are identified as approximately 75 km from the coastline, and this map identifies the most common impact class in t...

Human actions leading to coastal degradation
Physical alteration and the destruction of habitats are now considered one of the most significant threats to coastal areas. Half of the world’s wetlands, and even more of its mangrove forests, have been lost over the past century to physical alterations, the major causes being accelerating social and economic development and poor-planning (UNEP, 2002).
There are currently about one billion people living in coastal urban areas. It is estimated t...

Coastal populations and shoreline degradation
Unsurprisingly, the coastal areas with the greatest population densities are also those with the most shoreline degradation.
The areas surrounding the Black Sea, the Mediterranean and southern Asia have the highest proportion of altered land, while the coastal zones of the Arctic, northeast Pacific, south Pacific, West and Central Africa, East Africa, the Red Sea/Gulf of Aden, and Kuwait have the highest proportions of least modified land.

National environmental legislation, South Africa
The Working for the Environment programmes (water, fire, wetland, coast) are all supported by important national environmental legislation including the National Environmental Management: Biodiversity Act, the Disaster Management Act, the National Veld and Forest Fire Act, the National Environmental Management: Biodiversity Act, and the National Environment Management: Integrated Coastal Management Act.
