2015 GCRA ACTIVITIES
GCRA develops new projects in around 10 countries every year, but since we are constantly busy we never have time to keep the web page up to date, so it may seem we are up to nothing! Here is a list of some major projects done in 2015.
Indonesia continued to have most Biorock coral reef restoration projects in the world as Indonesian Biorock groups continued to install many new projects in Bali, Lombok, Java, Sulawesi, Ambon, Flores, and Sumbawa, with more constantly under development. Biorock Indonesia PT was formed as the umbrella group for future Biorock projects along with Yayasan Karang Lestari (Protected Coral Foundation, winner of the 2012 UN Equator Award for Community Based Development and the Special UNDP Award for Ocean and Coastal Management), and local partners. Tom Goreau taught the 10th Indonesian Biorock Coral Reef and Fisheries Restoration Training Workshop during the Bali Buleleng Dive Festival. Large, spectacular new projects were installed in Bali and Sulawesi. A Biorock shore protection reef to grow back an eroded beach was designed and installed in Sulawesi, and a similar project was designed in West Papua to be installed next year. An integrated whole-watershed and coastal zone nutrient, water, and soil management plan was drafted to protect the coral reefs of Pemuteran, Bali, from eutrophication, and collaboration with the Indonesian Biodiversity Research Center of Udayana University was established.
New Biorock coral reef, sea grass, and mangrove restoration projects were installed at the Galeta Marine Laboratory in collaboration with Dr. Stanley Heckadon of the Smithsonian Tropical Research Institution. The solar powered Biorock coral reef restoration project at Yandup, Uggupseni, Guna Yala (Autonomous Guna Indian territory) was expanded. This pilot project aims to save Guna islands now being abandoned due to sea level rise. All Panama Caribbean coral reefs underwent severe high temperature coral bleaching in 2015, affecting both Biorock projects. The Galeta Biorock project is located next to a similar unpowered control structure, so comparison of coral mortality and survival on the two structures will allow benefits of Biorock to be determined. We expect Biorock corals will show much higher coral recovery and survival based on results after severe bleaching events in the Maldives, Thailand, and Indonesia. When results are available they will be posted here.
The largest Biorock coral restoration project in the Caribbean was installed in Curaçao with Curaçao Divers. The project consists of 7 Biorock reefs linked together on the shelf slope. The corals show excellent growth, and fish populations are building up. The latest reports from Curaçao Divers will be reported here.
The Biorock coral reef restoration project in St. Barthelemy continued to show excellent growth of all four Acropora species (elkhorn, staghorn, and both hybrid varieties), as well as all other coral species, and has created an oasis of coral, fish and plankton in a barren, high wave stress environment. New Biorock coral reef restoration projects to restore deeper coral reefs, and to grow back shallow reefs to cause eroded beach sand to grow back naturally, were planned and approved for installation in 2016.
Cutting edge work on the response of sharks to low voltage direct current electrical fields was done in Bimini with Marcella Uchoa and Craig O’Neill. The dramatic results will be reported here when published. The Biorock coral reef and seagrass restoration project in Abaco continues to show excellent coral growth, spectacular seagrass growth, and dense fish populations, and our long term studies of corals killed by algae overgrowth and diseases near golf course nutrient sources continues.
An environmental assessment for restoration of threatened endemic species in the Sea of Cortez using Biorock mariculture methods, and for development of tidal current energy resources, was done, and approved by the Indigenous Comca’ac (Seri) Indian Ejido of Sonora. Pilot projects should start in early 2016
Biorock ecotourism coral restoration projects by Denis Schneider of Espace Bleu have expanded to more hotels in Bora Bora, Raiatea, and Moorea, and research has shown Biorock benefits for giant clams, pearl oysters, and corals. A collaborative proposal for research on effects of Biorock on coral settlement was funded by the French government and will start in early 2016.
Research projects with collaborators at the Plentzia Marine Laboratory of the University of the Basque Country in Spain found electrical fields resulted in greatly increased cell proliferation rates in mussel livers. Biorock minerals grown under different conditions were identified and their chemistry determined. Further research is underway on fundamental biophysical, biochemical, and cellular effects of the Biorock process.
Tom Goreau gave talks on climate, soil, water, and temperature interactions at the Conference on Restoring Water Cycles to Reverse Global Warming in Boston, and was active in leading the Soil Carbon Alliance efforts to urge governments to reverse global climate change through increasing soil carbon. The solar-powered Biorock coral reef restoration projects at Lauderdale By The Sea came to the end of their mandated three year monitoring program. The Town terminated all funding for the project and cut off the cables to the solar power buoys the Biorock team had designed and built to remove them. The project was literally cut off from power right during a severe high temperature coral bleaching event, when most needed! The project could easily be powered from a nearby fishing pier, but funding is crucially needed to save it.
Tom Goreau gave papers on use of wave energy to restore coral reefs and regrow beaches naturally at the Cuban Marine Science Congress, on soil carbon, climate change, and soil fertility restoration at the Cuban Agro-Ecology Conference, and met with coral reef and shore protection colleagues.
Tom Goreau gave several talks at the Paris UN Framework Convention on Climate Change as a delegate of the Caribbean Community Centre for Climate Change. These talks, in both government delegate areas and the public areas, focused on vulnerability of reefs and coasts to climate change, soil carbon to stabilize CO2 at safe levels, and on restoration of marine ecosystems, fisheries, and coasts.
These materials are summarized in the video links below:
New projects were approved for early 2016 in Italy, Papua, Indonesia, Vanuatu, and Saint Martin, and possibly more, while many requests for new projects came from a dozen more countries, but did not move forward due to lack of either funding or permission for serious marine ecosystem restoration.
In 2016 GCRA’s top priorities will be the global bleaching crisis caused by record global high temperatures and El Niño, documenting coral survival on bleached Biorock projects, reconnecting old Biorock projects in the Maldives before bleaching hits, starting new Biorock Coral Arks to maintain surviving coral populations in as many places as possible before impacts get worse, starting Biorock shore protection reef projects to grow eroded beaches back naturally in as many places as possible, and starting large-scale Biorock mangrove, sea grass, and salt marsh carbon restoration projects as possible, while continuing to promote soil carbon solutions to reverse global climate change from research, implementation, to global policy stages.
2016 KEY YEAR IN CORAL REEF EXTINCTION FROM GLOBAL WARMING
It is now 25 years since I showed the satellite sea surface temperature data at Al Gore’s US Senate Hearings on Climate Change proving that coral reefs were already being damaged by global warming, and that the threshold for severe coral bleaching was only 1 degree C. In 1992 at the signing of the Framework Convention on Climate Change in Rio de Janeiro I warned that the treaty would not prevent most corals from dying from high temperatures in the next 20 years. For 25 years governments have simply let the corals die, while denying there were global impacts of high temperature. Now they are mostly gone, and the Paris agreement is too weak to protect them. 2016 will be a record high temperature year, beating the 2015 record according to the UK Met Office. In 2015 severe coral bleaching hit Florida, Hawaii, Cuba, and Panama. It will be crucial to document all bleaching in 2016 in the hope that CO2 can be controlled in time to prevent the complete extinction of coral reefs, which is just possible if serious action were to start immediately both building Biorock Coral Arks to maintain temperature resistant populations where possible and reducing future impacts of global warming by increasing soil carbon.
