“On land, we are already exploiting mineral resources to the full,” says Jean-Baptiste Jouffray, of Stockholm University. “At the same time, the need for rare elements and metals is becoming increasingly important to supply green technologies such as wind and solar power plants. And so industrialists are looking to the seabed where it is now technologically and economically feasible to mine for minerals. Hence the arrival of threats to creatures like the scaly-foot snail.”
German and Chinese industrial groups have revealed plans to explore the seabed around two of the three vents that provide homes for scaly-foot snails. Should they proceed, and mine the seabed’s veins of metals and minerals, a large chunk of the snail’s home base will be destroyed and the existence of this remarkable little creature will be threatened.
“Blue acceleration”,is the term that is used by Jouffray and his co-authors to describe the recent rapid rise in marine industrialisation, a trend that has brought increasing ocean acidification, marine heating, coral reef destruction, and plastic pollution in its wake. As they state in their paper: “From the shoreline to the deep sea, the blue acceleration is already having major social and ecological consequences”.
Many seabed grabbers include small island states that are trying to become large ocean states in the process. For example, the Cook islands in the South Pacific has claimed an area of seabed that is 1,700 times its land surface. “The extension of the continental shelf is therefore not only transforming the geo-political landscape, it is also substantially shrinking the area designated as the common heritage of humankind,” states the report.
Examples of the conflicts that could ensue because of the blue acceleration include the disruption of key fish stocks by drilling for gas or oil offshore; pipelines that prevent trawl fishing; and offshore wind farms that disturb tourism.
Norway provides a stark demonstration of likely future conflicts. It aims to bring about fivefold rises both in salmon farming and cruise tourism in its waters over coming years while also building more and more offshore wind farms and more and more offshore gas and oil platforms. Seabed mining for minerals is also scheduled to begin. This saturation of ocean space renders Norwegian waters as being highly vulnerable to shocks, states the report.
The South China Sea is another potential flashpoint. It is a key gateway in the region’s network of undersea telecommunication cables; a third of the world’s shipping passes through it; while half the world’s fishing boats operate in its waters – which are disputed variously by China, Malaysia, Vietnam and others. Should armed conflict break out here over any of these issues, there would be a far-reaching impact on the world’s economy.
“The relevance of the ocean for humanity’s future is undisputed,” states the report. “However, addressing the diversity of claims, their impacts and their interactions, will require effective governance.”
To achieve this, the authors call for greater accountability to be imposed on those financing the fundamental changes that are now being made to Earth’s oceans. These include both banks and governments.
In addition, the vulnerability of small island states needs to be addressed, it adds: “Navigating the blue acceleration in a just and sustainable way requires particular emphasis on the implications of increased ocean use across the globe – and how these claims could have an impact on the economic safety and wellbeing of vulnerable communities and social groups"
