Oceans and Coastal Areas

Coastal threats

A recent global assessment of the risks of coastal degradation from development-related activities shows that 34 percent of the world's coasts are at high risk and another 17 percent at medium risk. The most threatened regions are Europe with 86 percent and Asia with 69 percent of their coastal ecosystems at risk (WRI/UNEP/UNDP/WB, 1996). The international response to this growing risk to ocean resources has been the adoption of the Global Programme of Action for the Protection of the Marine Environment from Land-based Activities at the Washington Conference in November 1995 (UNEP, 1995). New uses of the sea such as deep mineral exploitation will also create environmental impacts that need to be anticipated.
