Coral reefs are threatened by human activities

Coral reefs are threatened by human activities

In light of the ongoing destruction of coral reefs, up-to-date information on reef coverage and health is needed in order to ensure their protection by aid agencies, conservation organisations, industry and scientific communities. This information can be used to monitor changes, implement reef management strategies, predict fisheries statistics, plan shipping routes, and to aid scientific research, conservation and education.

Acting as an underwater nature reserve, marine protected areas (MPAs) have become an increasingly important reef management strategy, promoting responsible fishery management and habitat protection of the coral reefs and helping to restrict potentially damaging activities. They encompass both biological and social objectives, including reef restoration, biodiversity and economic benefits. However, efforts can sometimes be hampered by lack of participation, lack of perceived effectiveness or funding.

The Great Barrier Reef off the coast of Australia is protected by the Great Barrier Reef Marine Park Authority, and is the subject of much legislation, related to fishing (both commercial and recreational), biodiversity protection, climate change, shipping, water quality, coastal development and commercial marine tourism, amongst others.
