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.

Why mangroves matter: Experts respond on International Mangrove Day

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.

Deep-diving scientists say shallow reefs can’t rely on twilight zone systems for recovery

A team of highly trained scientific divers explored Pacific and western Atlantic reefs to test a widely held hypothesis that climate-stressed life from shallow reefs can take refuge at mesophotic depths.The results are clear: deep and shallow reefs are different systems with their own species, and deep reefs are just as threatened by climate impacts, storms, and pollution.

Belize Barrier Reef Reserve System removed from the List of World Heritage in Danger

Unesco, the world body’s educational, scientific and cultural agency, said its heritage committee voted Tuesday to remove the reef from its list of threatened sites because it no longer faced immediate danger from development.

Coral reefs ‘will be overwhelmed by rising oceans

Scientists have uncovered a new threat to the world’s endangered coral reefs. They have found that most are incapable of growing quickly enough to compensate for rising sea levels triggered by global warming.

Rise and fall of the Great Barrier Reef

A landmark international study of the Great Barrier Reef has shown that in the past 30,000 years the world’s largest reef system has suffered five death events, largely driven by changes in sea level and associated environmental change.

In pictures: Kenya’s coastal conservation heroes

Just 30 km south of the booming port town of Mombasa, residents of two tranquil Kenyan villages are making history. Here, amongst the mud-walled houses and coconut trees, the people of Gazi and Makongeni villages have become the world’s first communities to harness the carbon market through mangrove conservation.

Everglades under threat as Florida’s mangroves face death by rising sea level

Florida’s mangroves have been forced into a hasty retreat by sea level rise and now face being drowned, imperiling coastal communities and the prized Everglades wetlands, researchers have found.

Mangroves free of 500 tonne of plastic

February 24th, 2018

Nearly 500 tonne of plastic waste was removed from eight mangrove sites across Mumbai and suburban areas over the last two months. On an average, 70-80 tonne of plastic is removed every week, and 10-15 tonne every day.
