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.

Back from the brink: the global effort to save coral from climate change

Underwater nurseries offer glimmer of hope for endangered ecosystems, encouraging growth of coral fragments on fibreglass structures anchored to the seabed.

Climate change modifies the composition of reefs

Corals devastated by climate change are being replaced naturally by other species such as gorgonians, which are less efficient in acting as a carbon sink. A study has analyzes for the first time why gorgonians are more resistant than corals to human impacts and global climate change.

Catastrophic construction: Storms can build reef islands in atoll regions

Many coral reef islands, or atolls, are created by water moving sand and gravel, piling it up into consecutive ridged layers. However, new research has uncovered a different type of island construction: storm-deposited boulders.

Scientists in Fiji examine how forest conservation helps coral reefs

Researchers from the University of Hawai’i at Mānoa (UH Mānoa), WCS (Wildlife Conservation Society), and other groups are discovering how forest conservation in Fiji can minimize the impact of human activities on coral reefs and their fish populations.

Scientists discover hidden deep-sea coral reef off South Carolina Coast

In South Carolina, 160 miles off Charleston’s coast a giant deep-sea coral reef system has been hiding for thousands of years. The chief scientist who helped make the discovery called it unbelievable.

Muddy waters: Exploring mangrove governance in Tanzania

At the Global Landscapes Forum (GLF) in Nairobi later this month, a side event devoted specifically to mangrove preservation and restoration around the African continent’s coastlines will attract a range of stakeholders offering an opportunity to review lessons learned from research undertaken in the Rufiji Delta and mangrove ecosystems across the globe.

Children living on Indonesia’s coast get free goggles to enjoy – and save – precious reef

Indonesia’s maritime affairs minister has come up with an unconventional way to help preserve precious reefs from marine pollution: distribute boatloads of free goggles to children in the archipelago’s remote coastal regions. She wants to give next generation ‘the eyes’ to appreciate the marine world.

Mapping blue carbon in mangroves worldwide

Mangroves store greater amounts of carbon than any other terrestrial ecosystem, which helps reduce carbon dioxide and greenhouse gases in the atmosphere. When carbon is stored in the ocean or coastal ecosystems, it is called blue carbon. However, a more precise estimate of how much blue carbon is stored by mangroves has not been available until recently.

Given all that mangroves do, it is unsurprising that the forests have a special day dedicated to them: July 26, International Mangrove Day. However, mangroves have declined rapidly around the world. What does the disappearance of this special forest ecosystem mean for our planet? This is what some mangrove experts have to say.
