The Seascape Indonesia also includes critical habitats for globally threatened marine species, including sea turtles and cetaceans. Coral reefs Since 2001, the region has undergone rapid development in fisheries, oil and gas extraction, mining and Fisheries logging. The expansion of these sectors, combined with illegal activities and poorly planned coastal Sustainable development development, is accelerating deterioration of coastal and marine environments. At the same time, Marine protected areas regency governments have expanded their marine protected area networks to cover 3,594,702 ha of islands and coastal waters. Low population numbers, relatively healthy natural resources and a strong tenure system in eastern Indonesia provide an opportunity for government and local communities to col- laboratively manage their resources sustainably to ensure long-term food security, while meeting their development aspirations.
