- In Jordan, researchers, activists and fishers are hopeful that their coral reefs — and the life they help — can survive local weather change.
- Corals on this northern a part of the Pink Sea have been proven to be much more resilient to warming ocean temperatures than corals elsewhere.
- Despite the fact that they cowl solely 0.2% of the ocean ground, coral reefs help about 25% of all marine life.
AQABA, Jordan – Dozens of tiny, dazzlingly colourful fish swim round a maze of layer upon layer of corals. When divers method, they disguise close to a dome-shaped colony.
Within the clear, heat waters of Aqaba, clownfish, butterflyfish and angelfish swim subsequent to a navy tank intentionally sunk within the Nineties, now one in every of a number of wrecks which have turn out to be common diving websites. Over time, the tank changed into a habitat for numerous marine species as corals began rising on it.
With the pressures of local weather change, coral reefs are bleaching and dying globally at an unprecedented charge. Within the final 50 years, greater than half of the world’s coral reef cowl has been misplaced. Marine warmth waves are devastating corals within the Mediterranean Sea. Consultants predict that world warming and acidifying oceans might wipe out as much as 90% of corals within the coming many years.
However in Jordan, researchers are extra hopeful as corals present no indicators of mass bleaching.
“Corals within the Gulf of Aqaba can face up to larger temperatures,” says Jordanian conservationist Ehab Eid. “When many of the world’s corals are gone due to rising water temperatures, the corals in Aqaba could be the final remaining reefs.”
Whereas mass bleaching and demise happen when corals are uncovered to temperatures which are 1-2° Celsius (1.8-3.6° Fahrenheit) above their regular summer time most, scientists discovered that the reefs within the Gulf of Aqaba, on the northern tip of the Pink Sea, can survive an increase of 5-6°C (9-10.8°F).
This resilience is believed to be a product of how the corals migrated from hotter waters. Over the last ice age, some 20,000 years in the past, sea ranges fell, and the Pink Sea was lower off from the Indian Ocean. When the ice caps melted, the area was flooded once more, the Pink Sea grew to become reconnected and new life varieties made their means as much as the northern a part of the Pink Sea, the place water temperatures drop considerably. Solely the species tailored to the south’s heat waters had been capable of ship their larvae north to populate the Gulf of Aqaba.
Researchers discovered the corals within the north of the Pink Sea are nonetheless tailored to waters a lot hotter than their regular temperatures. In distinction to most corals elsewhere that stay near their thermal most, coral reefs within the Gulf of Aqaba have a a lot wider hole between bleaching threshold and most temperature.
However in response to Eid, regardless that the corals are resilient to excessive temperatures, they’re nonetheless susceptible to native stress from human exercise alongside the shoreline.
Shared between Jordan, Israel, Egypt and Saudi Arabia, the Gulf of Aqaba is underneath a number of strain from inhabitants progress, city growth and air pollution that might compromise the corals’ resilience.
Saudi Arabia is planning a futuristic mega metropolis bordering the Pink Sea. Additional south, specialists have warned a decaying oil supertanker anchored off Yemen might trigger catastrophic air pollution, whereas Israel and the UAE signed an settlement to permit oil to be moved from tankers within the Pink Sea. The deal was lately blocked by the Israeli minister for environmental safety, however the threats from city growth and inhabitants progress alongside the coast are anticipated to surge.
Safety issues in Jordan
The Jordanian metropolis of Aqaba is the gulf’s largest and most populous city heart. Since corals are near a significant inhabitants and industrial heart, Jordan’s fringing reefs are among the many most threatened within the Pink Sea.
“Aqaba is Jordan’s solely seaport, so there’s a number of strain from tourism, city growth and business,” says Abdullah Al-Momany, a marine biologist who manages the Pink Sea Dive Middle, Aqaba’s oldest diving heart.
In his 30 years as a diver, Al-Momany noticed Aqaba develop from a fishing city to a significant tourism vacation spot. “A variety of what I used to see is gone, so we have to do our greatest to protect what’s left of marine life,” he tells Mongabay.
“Aqaba is exclusive, it has one of many world’s highest range of species per sq. meter,” says Eid, who has spent years advocating for the safety of marine ecosystems in Jordan, the place 157 species of arduous corals and greater than 500 species of fish have been recognized.
In current many years, a number of mega tasks in Aqaba have aimed toward turning the area right into a hub for tourism, commerce and business. Final December, Jordanian authorities signed an settlement to develop a brand new cruise ship terminal to serve passengers visiting the Pink Sea. Plans to construct luxurious marinas, high-rises, personal resorts and business facilities have stepped up in recent times, however so have efforts to protect Jordan’s underwater treasures.
First established within the late Nineties to handle and protect Jordan’s marine biodiversity, Aqaba’s Marine Park changed into a protected space in 2020.
However strain on Jordan’s restricted shoreline, which spans some 27 kilometers (17 miles), has been intense. In 2006, Aqaba’s major port was moved to the south to an space stuffed with thousand-year-old corals. In cooperation with the United Nations Improvement Programme (UNDP), the Jordanian authorities translocated a portion of the corals to avoid wasting them from destruction.
“We moved the corals that had been thought of extra vulnerable to being impacted by the port,” says Nedal Al-Ouran, head of setting, local weather change and catastrophe threat discount on the UNDP. “Our staff managed to switch round 7,000 coral colonies. The survival charge is kind of excessive, round 85%.”
In keeping with Al-Ouran, the UNDP is working with native fishers, divers and the native tourism business on reef conservation and monitoring tasks: if the coral reefs are harmed, so are the ecosystems and economies that rely upon them.
“We used to have the ability to [catch] huge tuna, very huge sardines,” says Ibrahim Riady, who has fished in Aqaba for greater than 20 years. For Riady, as the town grew larger, the fish grew to become smaller. “There was once way more fish, larger fish,” he says. He worries that the enlargement of tourism and rising strain on the shoreline will have an effect on the reefs and fisheries his household will depend on as a supply of meals and earnings.
“If the corals are gone, the fish can even be gone,” Riady says. “So, in fact, we’re nervous.”
Despite the fact that they cowl solely 0.2% of the ocean’s ground, coral reefs help about 25% of all marine life. Along with offering meals and habitat for a lot of species, reefs additionally maintain not less than 500 million individuals all over the world, who rely upon marine ecosystems for his or her livelihoods.

Efforts to scrub, restore and shield Aqaba’s reefs
Leaning over her microscope, Maysoon Kteifan, a researcher at Aqaba’s Marine Science Station (MSS) specializing in coral restoration, says reefs are among the many most various and most vital ecosystems on the planet. “We have to do no matter we will to protect them. Right here on the station we are attempting our greatest to assist the environment restore,” she tells Mongabay.
“We began over 30 years in the past with small tasks, culturing corals right here within the lab,” says Fuad Al-Horani, a researcher at MSS and professor of coral biology on the College of Jordan. “Now we’ve got greater than 30 sea nurseries, with hundreds of coral colonies.”
Along with restoring broken corals and cultivating corals in labs and sea nurseries, researchers are additionally freezing cells and tissues in a coral financial institution to protect them for future use.
With Aqaba’s corals representing the most effective hope for the preservation of a significant reef by the top of the century, the efforts to revive and shield the reefs should not simply restricted to scientists and conservationists. Divers are enjoying a key function in elevating consciousness of the significance of reef conservation.
“We’re doing a number of cleansing dives, as a result of trash is an enormous drawback right here. Plastic baggage are killing our corals,” says dive operator Al-Momany, who established Aqaba’s Affiliation of Divers and organizes cleansing dives regularly.
“As divers we’ve got an enormous function to play in educating individuals methods to preserve a distance from corals and methods to shield them,” says Al-Momany, who has additionally accomplished a number of tasks in colleges, giving lectures concerning the significance of reef ecosystems.
Research discovered corals draped in plastic had been 20 instances extra prone to be confused, as plastics abrade corals and block daylight.
Within the final two years, divers Beisan Alsharif and Seif Al Madanat witnessed a rise within the quantity of trash they discovered underwater.
“We began seeing a lot waste, so many masks, plastic cups, containers,” Alsharif says. “It was hideous. So we mentioned we wanted to do one thing about it. We felt prefer it was our accountability.” Along with Al Madanat, she established Venture Sea to lift consciousness of the necessity to protect Aqaba’s marine ecosystem.
“We’ve got began a motion to vary the habits of littering,” Alsharif says. Along with organizing cleanup campaigns which have collected greater than 15,000 items of plastic in just some months, Alsharif says the venture can be creating on-line campaigns, reaching out to colleges and attempting to encourage youthful generations to become involved in marine conservation.
“If we preserve cleansing it up there’ll all the time be extra trash, so we have to tackle the core points,” she says.
Throughout the border, related conservation and restoration work is being accomplished within the Israeli port metropolis of Eilat. However for Anders Meibom, a professor on the College of Lausanne and the Swiss Federal Institute of Expertise who co-authored research on Aqaba’s distinctive warmth tolerance, efforts to guard Aqaba’s corals from native stresses should contain regional collaboration.
“Given how small the Gulf of Aqaba is, air pollution will unfold in a short time, it won’t respect worldwide borders,” he says.
In 2019, with help from the Swiss overseas ministry, Meibom and his colleagues established the Transnational Pink Sea Middle to advertise analysis and conservation, and encourage regional collaboration.
Meibom and different scientists and diplomats affiliated with the middle are calling on UNESCO to declare the Pink Sea reef as a marine World Heritage Web site. He says the popularity would shield the corals from native threats and make it simpler to draw funding for analysis, towards making better-informed selections on administration, restoration and conservation of the distinctive reefs.
“It’s an actual hope for humanity to protect a significant coral reef ecosystem for future generations,” Meibom says, “so we have to do all the things we will to guard it.”
