A marine protected area (MPA) is an area of sea especially dedicated to the protection and maintenance of biodiversity, and of natural and associated cultural resources, and managed through legal or other effective means. MPAs include marine parks, nature reserves and locally managed marine areas that protect reefs, seagrass beds, shipwrecks, archaeological sites, tidal lagoons, mudflats, saltmarshes, mangroves, rock platforms, underwater areas on the coast and the seabed in deep water, as well as open water (the water column). In 1988, The World Conservation Union (IUCN) General Assembly called upon national governments, international agencies and the non-governmental community to: Provide for the protection, restoration, wise use, understanding and enjoyment of the marine heritage of the world through the creation of a global, representative system of marine protected areas and through management in accordance with the principles of the World Conservation Strategy of human activities that use or affect the marine environment. In many parts of the world there is a growing focus and appreciation of the need for more MPAs and for better management generally of coastal and marine environments.

Coral reefs are one of the most spectacular and valuable ecosystems on the planet — and one of the most threatened. Climate change, coastal development and tourism, destructive fishing, and other human activities are endangering their very existence. At the current rate of destruction, more than one-third of the world’s coral reefs will be destroyed within our lifetime. This will mean devastating losses in biological diversity, shoreline protection, income, food, and scientific discoveries. However bad the outlook may seem, there is still hope for coral reefs. With increased education comes an increased appreciation and understanding of the immense value of coral reefs. This has led to exciting initiatives and conservation projects in countries throughout the world. Coral reef protected areas are being established worldwide and are considered one of the best tools for reef protection.

In this era of the global economy, tourism has become a primary source of revenue for many regions of the world, generating nearly $500 billion in worldwide revenues in 2001, and continuing to grow (WTO, 2001). The United Nations Environment Program recently facilitated a study which points out that the tourism industry now represents more than 10% of the world’s gross domestic product (UNEP, 2002). While tourism brings significant benefits for both local and global economies, its rapid growth and development in recent decades has caused widespread social and environmental change across the globe, particularly in popular coastal resort destinations. In contrast, the concept of sustainable tourism is now seen as a way to promote socio-economic development in a given region while simultaneously protecting local culture and the natural environment.

International waters is one of four focal areas of the Global Environment Facility (GEF). The GEF was created in 1994 to provide financing for programmes and projects to achieve global environment benefits in four focal areas: ?? biodiversity; ?? climate change; ?? international waters; and ?? and ozone layer depletion. International waters include oceans, large marine ecosystems, enclosed or semi-enclosed seas and estuaries as well as rivers, lakes, groundwater systems, and wetlands with trans-boundary drainage basins or common borders involving two or more countries. The ecosystems and habitats associated with these waters are essential parts of the system (IWP 2002c).
