Abu Dhabi has launched a coral reef rehabilitation project. It aims to culture one million coral reef colonies in Abu Dhabi waters in a bid to increase the emirate’s total coral reef area, protect the marine environment and prevent coastal erosion. It has been launched by the Environment Agency Abu Dhabi, the emirate’s environmental sector regulation, under the directives of Sheikh Hamdan Bin Zayed Al Nahyan, Ruler’s Representative in Al Dhafra Region, and EAD chairman.
The launch coincides with World Oceans Day, which is marked annually on June 8, Gulf News stated.
Dubai provides an ambitious project, too: it will create a vast reef (50 hectares!). It’s being grown on the artificial archipelago “The World” by the fragmentation method. This is implemented because 73% of the corals in the UAE have died due to human activities.
But there is a fly in the ointment in this story: the primary goal of the creators is to attract wealthy tourists to Heart of Europe hotels.
Importance of coral reefs
Coral reefs are known to provide a critical natural habitat for fish and other marine life and protect them from coastal erosion. However, global warming and the development of marine areas have led to the deterioration and bleaching of many reefs around the world.
Shaikh Hamdan therefore stressed the importance of Abu Dhabi’s project in preserving Abu Dhabi’s biological diversity, supporting fisheries, and enabling recreational activities and tourism.
“Despite the harsh environmental conditions for coral reefs here in the Arabian Gulf, they are able to adapt and provide habitats for a variety of marine species in the region. They are highly resilient, which enabled them to adapt to the highest temperatures in the world unusually, distinguishing it from other types of coral reefs,” Sheikh Hamdan said. According to EAD experts, Abu Dhabi contains 34 different types of hard corals.
Location of reefs
Mohamed Ahmed Al Bowardi, Minister of State for Defence Affairs and Vice Chairman of the EAD Board of Directors, said the hard corals are spread in several locations, including Ras Ghanada, Butinah, Saadiyat, and Alnouf.
“Through this program, nurseries for coral will be developed to reduce the negative impact of the natural pressures to which coral reefs are subjected due to climate change and high temperatures on the seafloor. As a result, the project will also increase the total coral area and rehabilitate affected areas to preserve the great heritage, economic and scientific value of the coral reefs,” Al Bowardi explained.
Threat to reefs
The increase in water temperatures is the biggest challenge facing coral reefs at present because it compounds thermal stress and results in coral bleaching. Razan Khalifa Al Mubarak, EAD managing director, said Abu Dhabi lost more than 73 % of its reefs due to mass coral bleaching in 2017.
“Such loss of coral reefs has been seen worldwide, including within the Great Barrier Reef in Australia, which has lost 50% of its living coral area. Through surveys conducted by EAD, an improvement of 10 % to 18 % in coral reef conditions has been monitored over the past year, which indicates the ability of coral reefs to recover if not exposed to climate change risks,” Al Mubarak said.
Since 2005, EAD has implemented a program to monitor and control the state of coral reefs through seasonal surveys, using data from 10 separate stations located across the emirate of Abu Dhabi. It has also developed a plan for managing and preserving the emirate’s coral reefs in coordination with all partners at the emirate level to understand and research coral reef ecosystems, reduce negative impacts and restore degraded reefs. In addition, EAD is cooperating with academic institutions on coral reef research; for example, with New York University Abu Dhabi on coral reef monitoring, Nawah Company, and Zayed University on laboratory propagation and replanting of coral reefs, said Shaikha Salem Al Dhaheri, EAD secretary-general.
“Through the implementation of the program, nurseries for corals will be developed. This will be achieved by harvesting small fragments of the various coral reef species in the emirate’s waters, relocating them to the nursery, and nurturing their growth until they can be re-transferred back to the degraded reefs for the establishment,” Al Dhaheri explained.
Increase reef area
“The project aims to reduce the negative impact of climate change on coral reefs, as well as increase the coral reef total area in the emirate’s waters, help to rehabilitate areas affected by climate change and human activities, and conduct research and studies to find out the best and most adaptable coral species,” she added.
In the first phase, which will last three years, nursery sites will be selected to ensure a protected environment for growth. This will involve evaluating coral sources and quality standards based on depth and temperature. Several underwater nurseries will be set up to nurture and grow coral fragments. The total production capacity is estimated to exceed one million coral colonies.
The program’s second phase includes harvesting coral nursery stocks, and transporting them to rehabilitation sites. Affected sites will also be cultivated to restore the integrated coral system. The third phase will include the completion of nursery stock harvesting and the restoration of degraded areas with new coral growth.
The EAD is currently developing a plan to manage and preserve coral reefs and submit proposals to expand and add some marine natural reserves with coral reefs.
Dubai’s luxury megaproject Heart of Europe is creating a vast coral reef
Off the coast of Dubai, a property developer plans to create up to 500,000 square meters of coral reef, CNN reports.
Kleindienst Group, the developer behind the Heart of Europe megaresort, which forms part of a network of artificial islands called “The World,” has set up The Coral Institute there to nurse and regenerate corals.
It uses a technique known as “fragmentation,” where pieces of coral are cut with a small electric saw, allowing each coral to regenerate hundreds of times potentially.
The pieces of coral will then be stored in water tanks, monitored, and nursed by a team of marine biologists until they grow enough to recreate a reef.
“The Coral Institute will hold and protect the genetic stock of corals … around the Arabian Gulf,” Josef Kleindienst, the chairman of Kleindienst Group, tells CNN.
A 2018 study found that 73% of corals in the UAE have been wiped out by bleaching, mainly due to climate change and human activity.
Kleindienst says that Heart of Europe’s goal is to show that development and marine life can co-exist in a sustainable environment. The corals will contribute to making the site eco-friendly, and they also will become a landscaping feature of the luxury hotels, 4,000 residential properties, and over 50 tourist attractions at the Heart of Europe, including the iconic Floating Seahorse Villas.
