In a bid to prevent more of the coral die-off that has been occurring since the 1980s, the Australian government is ramping up its dredging efforts, with the goal of completing a total of 40 kilometres of the Great Australia Reef by 2020.
However, many are sceptical that this will happen, given the difficulties in finding the right materials and in obtaining the necessary permits.
The Great Barrier Shield, which protects the Great Australian Reef from the rising seas, has suffered from a lack of funding and has been unable to cope with the damage caused by the massive influx of dredging materials.
The Australian government, however, is determined to get its dredge projects started.
In the first of a series of articles on the Great Britain and New Zealand dredging plans, RTE will be taking a closer look at some of the challenges faced by the dredging projects and some of their possible solutions.
In this first installment, we will examine the challenges facing the Great Great Barrier Reef in 2020 and look at the various options for managing the impacts.
In 2020The Great Australian Coral Reef is not the only one that is at risk from rising seas.
There are also other reefs in the world that are vulnerable to climate change and rising seas: The Great Barrier Islands, off the south west of Australia.
A recent study published in the journal Nature Climate Change found that by the middle of this century, the Great Basin would be home to almost one third of the world’s coral reefs.
However, the study also pointed out that the Great Southern Reefs in the west of the Southern Hemisphere, which are home to about half of all coral reefs worldwide, would also be at risk of decline by 2080.
Coral reefs can live for tens of thousands of years, with many species surviving to the present day.
In Australia, the reefs of the Northern Territory are the most vulnerable, with about one third (31%) of the reefs in Australia being under threat of loss by 2040.
As a result, in the first half of this decade, there has been a massive influx in dredging material, and the Great Northern Reef, the second most threatened coral reef in Australia, is already seeing significant declines.
Dredging of the northern Great Barrier is also taking place in the Great Pacific Garbage Patch, which covers more than 600,000 square kilometres of ocean, in New Zealand, where a major dredging project is underway.
The Great South Atlantic Garbage patch is an area that covers about 200,000 sq km, with more than 60% of the island’s reefs already in danger of extinction.
The reef is the world home to over half the coral reefs in New Guinea, which is also facing significant bleaching and degradation.
In contrast, the western Great Barrier Basin, which includes the Great South Australian Garbage patches, is the only place in Australia where coral reefs are still recovering from the previous bleaching event.
It is thought that as the bleaching subsides, the region will be able to return to its pre-bleaching conditions.
Dredged material will be carried from the southern Great Barrier to the Great Cape Coral, the eastern Great Barrier, and eventually to the northern Coral Sea, where it will be sent into the Great Ocean to be mined and processed.
Dredge materials will be transported on barges through the Great Bay, and on to the dredge pier where they will be unloaded into ships for transport to ports across the Great and Northern Seas.
As the Great Queensland Garbage and Waste Patch in Queensland continues to suffer from bleaching, the local government in Queensland is also investing in the dredged material recovery.
In September, the Queensland Government announced that it had committed $8.8 million over five years to dredge material to the area, with an additional $1.4 million for an extension of the program to 2020.
In total, the dredges in Queensland are expected to be worth $7.2 billion in total.
These investments will be used to restore the area’s marine life, and to ensure that the reef can recover by the end of the century.
