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.

Mangroves protect coastlines, store carbon – and are expanding with climate change

Mangroves are providing extremely valuable services and may become even more important as they expand toward the poles. But according to one recent study, many mangrove ecosystems are not building enough new elevation to keep pace with sea level rise.

Scientists Pinpoint How Ocean Acidification Weakens Coral Skeletons

The rising acidity of the oceans threatens coral reefs by making it harder for corals to build their skeletons. A new study identifies the details of how ocean acidification affects coral skeletons, allowing scientists to predict more precisely where corals will be more vulnerable.

2018 International Year of the Reef, UNEP

Over the last three decades, half of the planet’s coral has died under rising water temperatures and ocean acidification. To address this global crisis, global environmental leaders and countries have named this the International Year of the Reef.

Great Barrier Reef coral bleaching has started early, biologist says

Warm water has already begun bleaching coral on the Great Barrier Reef, weeks ahead of the period with highest forecast risk. Satellite data suggest widespread bleaching is possible by March.

The window for saving the world’s coral reefs is rapidly closing

For the first time, an international team of researchers has measured the escalating rate of coral bleaching at locations throughout the tropics over the past four decades. The study documents a dramatic shortening of the gap between pairs of bleaching events, threatening the future existence of these iconic ecosystems and the livelihoods of many millions of people.

Columbia Teen, NASA Partner In Mangrove Project: Report

A high school sophomore student has developed what might be the world’s first satellite-based early warning system to determine where mangroves are threatened. The work incorporates data from four satellites on mangrove growth and loss, rainfall, agriculture, and urban growth.
