Grand CommitteeMy Lords, this report makes it clear that the United Nations Convention on the Law of the Sea, and crucially the instruments that fall within its overarching framework, have helped to bring a welcome degree of certainty to the governance of the world’s waters, which, of course, cover the larger portion of the planet’s surface. It also underscores the ongoing importance of the convention and outlines how it continues to be crucial in addressing a range of important and difficult new maritime issues.
However, at the moment, UNCLOS does not answer all questions, nor does it provide a resolution to all issues. The report highlights the current gaps and challenges that are likely to emerge in the years ahead. As a maritime nation that relies on predictable and equitable rules at sea, it is important that the UK continues to take a leading role in the maintenance and development of UNCLOS and its subsidiary instruments.
At the same time, we must recognise that, no matter what we do, there will be issues that UNCLOS will not—or will not be allowed to—resolve. This is not an excuse for slackening our efforts to strengthen maritime governance, but it is important to recognise the limits of what is likely to be achievable and to think about how we manage the consequent challenges to international order. That is what I will focus on today.
The principal difficulty characterises international law more generally: there is no global government, so international law is essentially what the most powerful members of the international community decide it should be. We should not, therefore, be surprised that UNCLOS relies on consensus. This of course limits its scope when there is disagreement among the major players in the system, although we should note that, where there is consensus, we tend to get a high degree of compliance. However, compliance can also be a significant challenge. Just as there is no global government, there is no global enforcement mechanism that can be brought to bear on those who contravene international agreements. China’s repudiation of the 2016 UNCLOS ruling in favour of the Philippines regarding activities in the South China Sea—already mentioned several times this afternoon—clearly demonstrates the limits of the system.
Today I will highlight two challenges where in future UNCLOS may find itself constrained or even neutered. The first concerns the crucial issue of resource exploitation. The report covers the difficulties in regulating the development of deep seabed mining and fisheries management, but these will be greatly exacerbated by another factor, which is also discussed in the report and has been mentioned this afternoon: climate change.
The availability of an ice-free northern sea route from the east to the west will dramatically increase the commercial viability of maritime exploitation of the Atlantic by powers such as China, and this will have serious implications for fisheries. China’s demand for fish far outstrips its current supplies. Once its trawlers can access the Atlantic, we are likely to face a huge assault on fish stocks in that region. When I say “trawlers”, I am not talking about the sort of vessels that we can see sailing in and out of Brixham harbour; these are ships that are at sea for six months at a time and operate on an industrial scale.
We are likely to see a similar assault on non-living seabed resources. Despite the recent declarations made at COP 27, to which the noble Lord, Lord Teverson, referred, I suspect that the availability of strategic minerals will be like a magnet to resource-hungry nations, and the scale of China’s requirements will drive it to exploit the seabed wherever it can. Indeed, its activities in this regard have more than once been referred to as ocean rape. The International Seabed Authority will no doubt do its utmost to regulate such exploitation, but we have seen with the South China Sea how the PRC reacts to rulings that run counter to what it regards as its national interests. While we should continue to support such international governance mechanisms, we should also prepare now for an ice-free, Arctic route and the challenges this will bring. We should discuss with partner nations how together we might respond to those challenges in cases where international agreements prove powerless.
The other problem I want to highlight, already referred to by the noble Baroness, Lady Rawlings, is the security of subsea cables. The committee’s report emphasises their importance. Around 95% to 97% of global communications depend on them, and around 25% of the UK’s electricity is delivered through such cables. UNCLOS contains important provisions for their laying, maintenance and repair, but there are no comprehensive rules protecting maritime cables.
The report highlights areas where the UK should work to improve the regulatory environment in this regard, which of course is important. Better domestic legislation and closer co-operation with the International Cable Protection Committee are necessary steps in this regard, but, as with resources, we must recognise the likely limits of international law.
Subsea cables are crucial to our security and prosperity, but at the same time they are vulnerable. While accidental anchoring, fishing and natural disasters are the main threats to those cables in normal times, they are also obvious targets for hostile military action or, in future, for terrorist attack. UNCLOS will be of no help in the face of such risks. We need to develop comprehensive plans for the defence of subsea cables, but we also need to recognise that no defence can ever be perfect. This underlines the importance of developing sufficient resilience to be able to cope with successful attacks on those crucial assets. But that, as they say, is a whole other story.
In essence, the committee’s report confirms that UNCLOS, along with its subsidiary instruments, has on the whole been a huge success story, and it goes on to argue persuasively that the UK should work to develop the convention’s usefulness in the face of future challenges. I say amen to that, but, as I have argued, we must also be aware of the limitations that are inherent in any aspect of international law, UNCLOS not least, and prepare our responses to the inevitable and serious challenges that will face us as a consequence.
