Mangrove & Coral Destruction

Widespread destruction of mangroves (Bahamas, Australia) and Coral Reefs (Caribbean, Red Sea) has resulted in the loss of some of the worlds most diverse ecosystems. As a side effect, this has greatly increased shoreline hazards and beach erosion rates. The greatest benefit of mangroves is their ability to reduce storm surge. This benefit is long-term and requires no maintenance. The 1999 super typhoon, Orissa, killed over 10,000 people in India drowning many with its powerful storm surge. This number could have been lower if the mangroves had been retained. Mangroves are lost because of clearing for development, logging, and shrimp farming. Coral reefs are lost by mining (Bali, Indonesia), sedimentation from agriculture on the upland (St. Croix, Virgin Islands), bad fishing techniques that kill corals (Pacific Islands), sedimentation from nourished beaches (Waikiki) and a host of other natural and global warming-related causes. Dubai is perhaps the single greatest example of coral reef destruction. The artificial islands built there buried vast coral reefs. Mangroves and coral reefs often provide protection for nearby beaches. Their destruction harms the beach as well.

Fishermen Blast Premier Dive Sites off Indonesia

Coral gardens that were among Asia’s most spectacular, teeming with colorful sea life just a few months ago, have been transformed into desolate gray moonscapes by illegal fishermen who use explosives or cyanide to kill or stun their prey.The site is among several to have been hit inside Komodo National Park.

Rising Ocean Temperatures and Protected Coral Reefs

Special conservation zones known as marine protected areas provide many direct benefits to fisheries and coral reefs. However, such zones appear to offer limited help to corals in their battle against global warming, according to a new study.

Australian Government’s Great Barrier Reef Plans’ Questioned

A monitoring mission from the UN educational and cultural arm, UNESCO, will visit Queensland next month to examine concerns about major port developments and other potential threats to the World Heritage listed reef, as WWF challenged the Australian Government’s view that the Great Barrier Reef is being sustainably managed, citing publications showing that coral had declined by up to 50 per cent.

New Caledonia’s Lagoon: Better Understanding for Better Protection

April 21st, 2011

New Caledonia possesses the second largest coral reef lagoon on Earth and harbours an exceptional biodiversity. The island is also the world’s third most important nickel producer. Ore extraction over the 20th Century has in places tripled the input of sediments and accompanying pollutants, such as metals, in the marine environment.

Last Chance Beach, Battling Erosion in Barbados

February 25th, 2011

Around Barbados, the most serious threat to the beaches is the loss of coral reefs through nearshore pollution, primarily caused by domestic sewage, and physical clearing. As the reefs die, they lose their ability to reduce the energy and erosive force of incoming waves.
