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.

According to a study conducted by Japanese and Filipino scientists, coral cover in Boracay Island declined by about 70.5 percent from 1988 to 2011, and the highest decrease in the 23-year period, was recorded between 2008 and 2011, as tourist arrivals rose by 38.4 percent…

After Oil Spill, Unique Mangrove Forest Faces More Threats

tiger-mangrove

On December 9, 2014, a wrecked tanker released approximately 94,000 gallons of heavy fuel oil into the Shela River, which runs through the Sundarbans. Now another shipping disaster is unfolding, as a capsized cargo vessel, Jabalenoor, leaks 200 tonnes of potash fertilizer into the Sundarbans’ Bhola River, southeast of the earlier oil spill.

Ocean-scale Dataset Allows Broad View of Human Influence on Pacific Coral Reef

coral-bleaching-coastal-care

A study draws on data from nearly 40 islands and atolls across the central and western Pacific, including 25 unpopulated islands, to investigate the relative influence of environmental variation and human presence on reef fish assemblages. The resulting message is sobering.

Communities Leading the Way to Save Madagascar’s Mangroves

A recent study carried out by the University of Antananarivo and Blue Ventures found that between 1990 and 2010, Ambanja and Ambaro Bays lost approximately 20 percent of their mangroves. In northwest Madagascar, charcoal production for urban markets is the biggest driver of this loss.

Coastal Mangrove Squeeze in the Mekong Delta

The role of mangrove forests in providing coastal zone stability and protection against flooding is increasingly recognized. The specific root, stem, and canopy system of mangroves is highly efficient in attenuating waves and currents. The sheltered environment created by a healthy mangrove forest offers great sedimentation potential.

Along Cuba’s Coast, The Last Best Coral Reef in the Caribbean Thrives

March 4th, 2015

While coral reef cover has declined by 50 percent throughout the Caribbean, Cuba has managed to retain some of the most pristine coral reef environments on earth. Lack of coastal development, limited tourism, small amounts of runoff flowing into the sea, tight controls on commercial fishing, and the establishment of extensive marine protected areas have all combined to give Cuba the most remarkable coral reef environments in the Caribbean.
