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.

Actions to save coral reefs could benefit all ecosystems

Scientists say bolder actions to protect the world’s coral reefs will benefit all ecosystems, human livelihoods and improve food security.

These little organisms are saving the coastlines from monster storms. Be nice to them

The catastrophe in the Bahamas shows more clearly than ever that coastal communities around the world are in dire peril from supercharged storms like Hurricane Dorian. They need to preserve and restore their first line of defense, wetlands and coral reefs. They need to build what scientists like me call coastal resilience.

Great Barrier Reef health outlook downgraded to “very poor” due to ocean warming

The government agency that manages Australia’s Great Barrier Reef has downgraded its outlook for the corals’ condition from “poor” to “very poor” due to warming oceans.

How to restore a coral reef

New guidelines drafted by a consortium of concerned experts could enable corals to adapt to changing environments and help restore declining populations in the Caribbean. The guidelines provide a definitive plan for collecting, raising, and replanting corals that maximizes their potential for adaptation.

Abu Dhabi is replanting mangroves in the fight against climate change

The coastal city of Abu Dhabi is one of the most vulnerable places in the world to the impacts of climate change. It’s threatened by rising sea levels and researchers say it could be too hot to live in by the end of this century if global warming trends continue. But mangroves trees are helping the city fight the climate crisis…

Thirty years of unique data reveal what’s really killing coral reefs

Coral bleaching is not just due to a warming planet, but also a planet that is simultaneously being enriched with reactive nitrogen from sources like improperly treated sewage, and fertilizers.

On Java’s Coast, A Natural Approach to Holding Back the Waters

The Indonesian island of Java has lost 70 percent of the mangroves that once protected its coast from erosion and flooding. Now villagers are using natural wooden barriers to try to restore the mangrove forests and save their lands and homes from being washed away.

Coral study traces excess nitrogen to Maui wastewater treatment facility

A new method for reconstructing changes in nitrogen sources over time has enabled scientists to connect excess nutrients in the coastal waters of West Maui, Hawaii, to a sewage treatment facility that injects treated wastewater into the ground.

Fish diversity linked to Caribbean coral reef health

March 6th, 2019

The health of coral reefs can be impacted as much by the diversity of fish that graze on them as by the amount of fish that do so, according to a new study. In the paper, the researchers untangle and unveil the powerful effects that biodiversity has on Caribbean coral reefs.
