Convention on Wetlands of Global Importance
Signed in Ramsar, Iran in 1972, the convention today combines the
efforts of 138 contracting parties. It has encouraged the designation
of 1,328 wetlands with an area of 112 million hectares as worthy
of international importance. The Convention provides the framework
for international cooperation for the conservation and wise use
of wetlands and their resources.
As part of their commitment, parties have to designate sites for
the Ramsar List of Wetlands of International Importance. Sites on
the list must be managed to avoid changes in their "ecological character."
