Contrary to the view that the South China Sea disputes are driven by a regional hunger for seabed energy resources, the real and immediate prizes at stake are the region’s fisheries and marine environments that support them.

It is also through the fisheries dimensions to the conflict that the repercussions of the recent ruling of the arbitration tribunal in the Philippines-China case are likely to be most acutely felt.

It seems that oil is sexier than fish, or at least the lure of seabed energy resources has a more powerful motivating effect on policymakers, commentators and the media alike. However, the resources really at stake are the fisheries of the South China Sea and the marine environment that sustains them.

The real resource at stake

For a relatively small (around 3 million square kilometres) patch of the oceans, the South China Sea delivers an astonishing abundance of fish. The area is home to at least 3,365 known species of marine fishes, and in 2012, an estimated 12% of the world’s total fishing catch, worth US$21.8 billion, came from this region.

These living resources are worth more than money; they are fundamental to the food security of coastal populations numbering in the hundreds of millions.

Indeed, a recent study showed that the countries fringing the South China Sea are among the most reliant in the world on fish as source of nutrients. This makes their populations especially susceptible to malnutrition as fish catches decline.

These fisheries also employ at least 3.7 million people (almost certainly an underestimate given the level of unreported and illegal fishing in the region).

This is arguably one of the most important services the South China Sea fisheries provide to the global community – keeping nearly 4 million young global citizens busy, who would otherwise have few employment options.

But these vital resources are under enormous pressure.

A disaster in the making

The South China Sea’s fisheries are seriously over-exploited.

Last year, two of us contributed to a report finding that 55% of global marine fishing vessels operate in the South China Sea. We also found that fish stocks have declined 70% to 95% since the 1950s.

Over the past 30 years, the number of fish caught each hour has declined by a third, meaning fishers are putting in more effort for less fish.

This has been accelerated by destructive fishing practices such as the use of dynamite and cyanide on reefs, coupled with artificial island-building. The coral reefs of the South China Sea have been declining at a rate of 16% per decade.

Even so, the total amount of fish caught has increased. But the proportion of large species has declined while the proportion of smaller species and juvenile fish has increased. This has disastrous implications for the future of fishing in the South China Sea.

We found that, by 2045, under business as usual, each of the species groups studied would suffer stock decreases of a further 9% to 59%.

The ‘maritime militia’

Access to these fisheries is an enduring concern for nations surrounding the South China Sea, and fishing incidents play an enduring role in the dispute.

Chinese/Taiwanese fishing fleets dominate the South China Sea by numbers. This is due to the insatiable domestic demand for fish coupled with heavy state subsidies to enable Chinese fishers build larger vessels with longer range.

Competition between rival fishing fleets for a dwindling resource in a region of overlapping maritime claims inevitably leads to fisheries conflicts. Fishing boats have been apprehended for alleged illegal fishing leading to incidents between rival patrol boats on the water, such as the one in March 2016 between Chinese and Indonesian vessels.

Fishing boats are not just used to catch fish. Fishing vessels have long been used as proxies to assert maritime claims.

China’s fishing fleets have been characterised as a “maritime militia” in this context. Numerous incidents have involved Chinese fishing vessels operating (just) within China’s so-called nine-dashed line claim but in close proximity to other coastal states in areas they consider to be part of their exclusive economic zones (EEZs).

The Chinese Coast Guard has increasingly played an important role in providing logistical support such as refueling as well as intervening to protect Chinese vessels from arrest by the maritime enforcement efforts of other South China Sea coastal states.

Fisheries as flashpoint

The July 2016 ruling in the dispute between the Philippines and China demolishes any legal basis to China’s claim to extended maritime zones in the southern South China Sea and any right to resources.

The consequence of this is that the Philippines and, by extension, Malaysia, Brunei and Indonesia are free to claim rights over the sea to 200 nautical miles from their coasts as part of their EEZs.

This also creates a pocket of high seas outside any national claim in the central part of the South China Sea.

There are signs that this has emboldened coastal states to take a stronger stance against what they will undoubtedly regard as illegal fishing on China’s part in “their” waters.

Indonesia already has a strong track record of doing so, blowing up and sinking 23 apprehended illegal fishing vessels in April and live-streaming the explosions to maximise publicity. It appears that Malaysia is following suit, threatening to sink illegal fishing vessels and turn them into artificial reefs.

The snag is that China has vociferously rejected the ruling. There is every indication that the Chinese will continue to operate within the nine-dashed line and Chinese maritime forces will seek to protect China’s claims there.

This gloomy view is underscored by the fact that China has recently opened a fishing port on the island of Hainan with space for 800 fishing vessels, a figure projected to rise to 2,000. The new port is predicted to play an important role in “safeguarding China’s fishing rights in the South China Sea”, according to a local official.

On August 2, the Chinese Supreme People’s Court signalled that China had the right to prosecute foreigners “illegally entering Chinese waters” – including areas claimed by China but which, in line with the tribunal’s ruling, are part of the surrounding states' EEZs – and jail them for up to a year.

Ominously, the following day Chinese Defence Minister Chang Wanquan warned that China should prepare for a “people’s war at sea” in order to “safeguard sovereignty”. This sets the scene for increased fisheries conflicts.

Ways forward

The South China Sea is crying out for the creation of a multilateral management, such as through a marine protected area or the revival of a decades-old idea of turning parts of the South China Sea, perhaps the central high seas pocket, into an international marine peace park.

Such options would serve to protect the vulnerable coral reef ecosystems of the region and help to conserve its valuable marine living resources.

A co-operative solution that bypasses the current disputes over the South China Sea may seem far-fetched. Without such action, however, its fisheries face collapse, with dire consequences for the region. Ultimately, the fishers and fishes are going to be the losers if the dispute continues.

New report finds ‘that the energy of 87% of vehicle-days could be met by an existing, affordable electric vehicle’ – but that’s not quite good enough

Electric cars could take over most driving necessities tomorrow, according to a group of scientists at the Massachusetts Institute of Technology, but they’ll need the help of internal combustion engines to do it.

Using travel surveys and global positioning data, the MIT team has evaluated the possible widespread use of electric cars, and has found that grids could easily support today’s cheap electric cars, and that the cars themselves can already meet drivers’ requirements almost nine times out of 10.

Today’s carbon pollution will have climate consequences for centuries to come. We’re in the midst of a critical decade

While most people accept the reality of human-caused global warming, we tend not to view it as an urgent issue or high priority. That lack of immediate concern may in part stem from a lack of understanding that today’s pollution will heat the planet for centuries to come, as explained in this Denial101x lecture:

The United Nations climate change conference held last year in Paris had the aim of tackling future climate change. After the deadlocks and weak measures that arose at previous meetings, such as Copenhagen in 2009, the Paris summit was different. The resulting Paris Agreement committed to:

Holding the increase in the global average temperature to well below 2°C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5°C above pre-industrial levels, recognising that this would significantly reduce the risks and impacts of climate change.

The agreement was widely met with cautious optimism. Certainly, some of the media were pleased with the outcome while acknowledging the deal’s limitations.

Many climate scientists were pleased to see a more ambitious target being pursued, but what many people fail to realise is that actually staying within a 1.5℃ global warming limit is nigh on impossible.

There seems to be a strong disconnect between what the public and climate scientists think is achievable. The problem is not helped by the media’s apparent reluctance to treat it as a true crisis.

The 1.5℃ limit is nearly impossible

In 2015, we saw global average temperatures a little over 1℃ above pre-industrial levels, and 2016 will very likely be even hotter. In February and March of this year, temperatures were 1.38℃ above pre-industrial averages.

Admittedly, these are individual months and years with a strong El Niño influence (which makes global temperatures more likely to be warmer), but the point is we’re already well on track to reach 1.5℃ pretty soon.

So when will we actually reach 1.5℃ of global warming?

On our current emissions trajectory we will likely reach 1.5℃ within the next couple of decades (2024 is our best estimate). The less ambitious 2℃ target would be surpassed not much later.

This means we probably have only about a decade before we break through the ambitious 1.5℃ global warming target agreed to by the world’s nations in Paris.

A University of Melbourne research group recently published these spiral graphs showing just how close we are getting to 1.5℃ warming. Realistically, we have very little time left to limit warming to 2℃, let alone 1.5℃.

This is especially true when you bear in mind that even if we stopped all greenhouse gas emissions right now, we would likely experience about another half-degree of warming as the oceans “catch up” with the atmosphere.

Parallels with climate change scepticism

The public seriously underestimates the level of consensus among climate scientists that human activities have caused the majority of global warming in recent history. Similarly, there appears to be a lack of public awareness about just how urgent the problem is.

Many people think we have plenty of time to act on climate change and that we can avoid the worst impacts by slowly and steadily reducing greenhouse gas emissions over the next few decades.

This is simply not the case. Rapid and drastic cuts to emissions are needed as soon as possible.

In conjunction, we must also urgently find ways to remove greenhouse gases already in the atmosphere. At present, this is not yet viable on a large scale.

Is 1.5℃ even enough to avoid “dangerous” climate change?

The 1.5℃ and 2℃ targets are designed to avoid the worst impacts of climate change. It’s certainly true that the more we warm the planet, the worse the impacts are likely to be. However, we are already experiencing dangerous consequences of climate change, with clear impacts on society and the environment.

For example, a recent study found that many of the excess deaths reported during the summer 2003 heatwave in Europe could be attributed to human-induced climate change.

Also, research has shown that the warm seas associated with the bleaching of the Great Barrier Reef in March 2016 would have been almost impossible without climate change.

Climate change is already increasing the frequency of extreme weather events, from heatwaves in Australia to heavy rainfall in Britain.

These events are just a taste of the effects of climate change. Worse is almost certainly set to come as we continue to warm the planet.

It’s highly unlikely we will achieve the targets set out in the Paris Agreement, but that doesn’t mean governments should give up. It is vital that we do as much as we can to limit global warming.

The more we do now, the less severe the impacts will be, regardless of targets. The simple take-home message is that immediate, drastic climate action will mean far fewer deaths and less environmental damage in the future.
