COP26: Climate change and the seafood supply chain

Futureproofing the trade goes to contain each decreasing seafood impression on local weather and adapting to local weather impression on seafood, writes Angus Garrett, head of horizon scanning at Seafish

You’ll be able to’t entry many newsfeeds nowadays with out some point out of carbon emissions and the local weather ‘emergency’. World local weather change is now recognised as a serious problem for the world, prompting a name for motion by authorities, trade and wider society.

What appears to get misplaced within the noise is that local weather change is interlinked with different international challenges resembling meals safety.

A warming local weather should be addressed, however the world nonetheless must be fed. The marine surroundings performs an vital function in regulating the worldwide local weather. Additionally it is an vital meals supply.

Within the seek for lowered emissions, meals might be a straightforward goal. All meals manufacturing depends on pure sources, and it seems that meals makes a sizeable contribution to international local weather change – some 20-30% of all human-derived emissions.

This brings local weather and meals manufacturing into sharp focus. Can we tackle international local weather change and feed the world on the identical time?

What issues is the impression of various meals manufacturing techniques. Within the spherical, nearly half of food- associated emissions are attributed to livestock. In distinction, it has been estimated that 4% of emissions from international meals manufacturing might be attributed to fisheries. Seafood emissions are comparatively low: the carbon footprint for some species is amongst the bottom for animal proteins. This makes seafood a ‘climate-smart’ meals alternative – with out it, we’d need to rely extra on higher-impact meals.

But, nonetheless climate-smart seafood could be, it may also be impacted by a altering local weather. That is unsure territory, as a result of it isn’t clear what modifications a warming world will deliver, nor when. Some modifications are occurring already, resembling more and more extreme strorms and waves, and air and water temperature modifications. They may irritate issues round vessel operation and crew security, injury to port infrastructure, the distribution of some wild-caught species, and species that may be farmed.

Different modifications are longer-term and extra unsure.

Extra rainfall could also be seen within the UK by 2040, while sea-level rise and ocean acidification might happen by 2070. This might deliver flooding, water high quality and salinity points in nearshore waters, and have an effect on the flexibility of fish and shellfish to thrive.

Mitigation and adaptation

Regardless of this uncertainty, local weather change is an issue right now, not only a potential impression in some distant future.

A give attention to decreasing emissions, and seafood’s impression on local weather, may imply main modifications within the seafood provide chain. Efforts to protect ‘blue carbon shops’ may have an effect on the catching sector – excluding vessels from sure areas, closing some fisheries to permit marine restoration, or limiting fishing to sure gear varieties.

Lowering transport emissions may have an effect on UK seafood commerce – for instance, the air-freighting of high-value seafood, since we import a lot of the seafood we eat and export most of what we catch. Extra broadly, entry to clients or elevating capital could also be more difficult with out carbon credentials.

Though seafood is ranging from a great place as a climate-smart protein, there are alternatives to additional cut back that low carbon footprint. The trade can give attention to making enhancements in areas the place emissions are comparatively excessive – so-called ‘hotspots’ like gas use in catching, aquaculture feed, transport by air freight, and yield/ waste from uncooked supplies.

Key steps can, and are, being taken by the trade. These embody investing in energy-efficient gear and vessels, various lower-carbon feed sources for aquaculture manufacturing, and exploring options to air freight by combining cooling know-how with sea freight.

Nevertheless, to make sure a resilient provide of climate-smart meals, companies can even have to adapt to a warming world and local weather impacts on seafood. There is no such thing as a silver bullet, so a variety of variations are wanted. Business, authorities and researchers all have a job to play.

Some actions, already underway, aren’t essentially prompted by local weather change however are useful variations nonetheless. For instance, some components of the fleet are introducing crew enclosures and lined areas, while pelagic vessels are pumping from the strict moderately than the aspect. Some ports, resembling Peterhead, are investing closely in port infrastructure that may assist defend towards storm surges.

Anticipating the potential for flood occasions, some processors have undertaken contingency planning for worse-case eventualities to make sure clients obtain seafood orders. These steps may also help the trade cope higher with more and more stormy climate. There are additionally efforts to higher perceive the results of temperature change.

COP26 and seafood companies

The local weather problem has been a priority for over 30 years, and can proceed to be so for many years to come back. The problem is being thought of globally, nationally and at an area degree, and will come to dominate our lives and that of coming generations.

At a worldwide degree, because the mid-Nineteen Nineties, the UN has co-ordinated the annual Convention of the Events (COP). The COPs deliver governments and others collectively to evaluate progress on decreasing emissions, and agree additional responses.

Through the years, targets have been agreed and ambition set out, most not too long ago – in Paris – to ‘obtain a climate-neutral world by mid-century’. These conferences additionally present area for dialogue on particular pursuits, resembling how ocean environments must be managed within the face of local weather change.

Local weather change can also be on the agenda at a nationwide degree. Commitments to behave have already been made by the UK authorities and devolved administrations, together with throughout the UK Fisheries Act 2020.

These discussions could appear distant and obscure, however they will come near dwelling. With COP26 in Glasgow this week, there’s already scrutiny on what’s taking place within the UK’s yard.

These outdoors the trade aren’t shy in coming ahead to say what must be finished, not at all times recognising the significance of meals provision. Selections could also be taken with the very best of intentions, solely to end in unintended penalties; that is the place a give attention to the meals system will likely be vital.

We have to pay shut consideration to those discussions and make sure that fishing, aquaculture and the seafood commerce are recognised for the vital function they play in climate-smart meals manufacturing.
