Remote Indian Ocean reefs bounce back quickly after bleaching

Published

Coral reefs in remote or protected areas can recover quickly after mass coral bleaching events, new research shows.

University of Exeter researchers are investigating “reef carbonate budgets” — the net production or erosion of reef structure over time, said a report published by Science Daily

To study the impacts of climate change on reef functions, they examined 12 reefs in the remote Chagos Islands in the Indian Ocean before and after the global coral bleaching event in 2015/16.

In 2018, the formerly thriving reefs were “shrinking,” with coral cover and carbonate production down by more than 70% and erosion processes exceeding new coral growth.

When the researchers returned in 2021, all reefs were on a trajectory of recovery, although the speed varied from place to place.

Where key coral species returned quickly and the underlying physical reef structure had stayed intact, reefs showed a rapid transition back to positive growth only six years after the bleaching event.

Bleaching is caused by warmer water temperatures, which can trigger corals to expel their symbiotic algae and turn white. Corals can survive this, but an extreme heat wave causes large-scale mortality.

The speed of subsequent recovery is an important indicator of a reef’s health and resilience.

“Such high rates of coral recruitment and the rapid restoration of reef functions are a very nice surprise and imply that this location is showing some resilience, thus far, to ongoing ocean warming,” said lead author Dr Ines Lange, a postdoctoral research fellow in a multi-institutional project funded by the Bertarelli Program in Marine Science.

“A full recovery of reefs across the Chagos Archipelago over the next few years is likely if the region is spared from reoccurring marine heating events.”

Dr Lange added: “The study shows that in remote and protected areas without local impacts such as fishing or pollution from land, coral reefs and the important functions they provide are able to recover relatively quickly, even after large-scale disturbances.

“Proximity to healthy coral populations and the maintenance of a complex reef structure seems to boost recovery speed, which may help to manage reefs under the threat of increasing frequency of bleaching events predicted for the near future.”

Co-author Professor Chris Perry, from the University of Exeter, developed the census-based ReefBudget method to quantify reef carbonate budgets.

These carbonate budgets are important indicators of a reef’s ability to provide habitat to marine life, protect shorelines from wave energy and help reef islands to keep up with future sea level rise.

Over the last years, Prof Perry and Dr Lange optimised the method for the central Indian Ocean by quantifying and integrating local rates of coral growth and parrotfish erosion.

Developing the human resources needed for construction projects remains a key challenge before us – PM

Published

Prime Minister Dr. Harini Amarasuriya stated that the Government has already allocated substantial funds for future development activities, including the restoration of areas damaged by the recent cyclone Ditwah, and that one of the key challenges currently faced is securing the necessary human resources, particularly technical personnel, required to carry out the construction and development projects.

The Prime Minister made these remarks on Friday [June 19]  in Kandy while paying a visit on the Mahanayaka Theros of the Malwathu and Asgiri Chapters.

During her visit to the Malwathu Maha Viharaya in Kandy, the Prime Minister met with the Most Venerable Thibbatuwawe Sri Siddhartha Sumangala Mahanayaka Thero, Mahanayaka of the Malwathu Chapter, as well as the Anunayaka Theros of the Chapter, the Most Venerable Niyangoda Vijithasiri Thero and the Most Venerable Dimbulkumbure Wimaladhamma Thero. The Prime Minister also engaged in a discussion with the Mahanayaka Thero.

Subsequently, the Prime Minister paid a visit to the Most Venerable Warakagoda Gnanarathana Mahanayaka Thero, Mahanayaka of the Asgiri Chapter of the Siam Maha Nikaya of Sri Lanka, and the Anunayaka of the Asgiri Chapter, the Most Venerable Narampanawa Ananda Thero.

During the discussions, the Prime Minister briefed the Mahanayaka Thero on the current progress of the new education reforms. She also stated that measures would be taken to recruit teachers in the near future to address the existing teacher shortage. She further noted that the evaluation of answer scripts from the recently held teacher recruitment examination is currently underway and that successful candidates will be recruited expeditiously following a practical assessment.

The occasion was attended by the Members of Parliament, the Secretary to the Ministry of Education, Higher Education and Vocational Education, Nalaka Kaluwewa, and several other officials.

Children should gain experience through activities such as aesthetics and sports from the primary education stage – PM

Published

By

Minister of Education, Higher Education and Vocational Education, Prime Minister Dr. Harini Amarasuriya, stated that if Sri Lanka is to nurture the future leaders, children must be exposed from the primary education itself to the experiences and values gained through fields such as aesthetics and sports.

The Prime Minister made these remarks while participating in the “Punchi Hapannu 2026” occasion to recognize and appreciate the winners of the Primary Literary Skills, held on Thursday [8 June]at Polpithigama National School during an educational inspection tour in the Kurunegala District.

The event was organized to recognize the winners of the “Punchi Hapannu 2026” Language and Literary Skills Competition, which was conducted with the participation of students from 49 primary schools in the Polpithigama Education Division, based on a concept initiated by the Divisional Director of Education. The occasion was further featured by aesthetic performances presented by students who had won across 17 different competition categories.

During the event, certificates were awarded to the winners by the Prime Minister.

Addressing the occasion, the Prime Minister further stated:

“The initiative undertaken within the Polpithigama Education Division is an example for the entire country. Primary education is a broad and multifaceted field. The foundation provided through primary education is important in guiding a child along the right path. A child has only one opportunity in life to experience primary education, and it is our responsibility to ensure that this opportunity is provided in the most appropriate way.

Today, we witnessed how effectively the children of the Polpithigama Education Division utilized the opportunity given to them to creatively showcase their aesthetic talents. Likewise, we are striving to build an education system that provides opportunities for children across Sri Lanka to develop their hidden talents”.

Following the ceremony, the Prime Minister visited Makulpotha Maha Vidyalaya in the Polpithigama Education Division and  layed the foundation-stone for a new two-storey school building.

The construction project, implemented with an investment of Rs. 45 million, is scheduled to be completed in 2026 and handed over for students in January 2027.

The event was graced by the presence of members of the Maha Sangha, and attended by the Deputy Minister of Agriculture and Livestock Namal Karunaratne, Kurunegala District Member of Parliament Attorney-at-Law Geetha Herath, education officials of the North Western Province, parents, principals, and several other invitees.
