The oceans have an increasing potential to provide food for a global population. The challenge is how to do so without harming the planet or its people. Chris Stokel-Walker discovers ideas, organisations and investors helping aquaculture towards a sustainable future

The ocean is an essential pillar of planetary life, sustaining and feeding billions worldwide. Quite aside from its ability to capture and sequester harmful emissions, our planet’s waters are a major driver of keeping us alive – for drink and for food. Three billion of us depend on wild-caught and farmed seafood as a primary source of protein – which makes it vital that the ocean is kept as a bountiful natural resource.

Aquaculture is the breeding and harvesting in water of fish, shellfish and other marine life. It is underwater farming, in short, and it is crucial to humankind. “Aquaculture is an essential food source, especially in our changing climate,” says Danielle Blacklock, Director of the Office of Aquaculture at the United States’s National Oceanic and Atmospheric Administration (NOAA). “Globally, aquaculture supplies more than 50 per cent of all seafood produced for people to eat – a percentage that will keep rising. And expanding domestic aquaculture presents important opportunities to bolster climate– smart and resilient food systems.”

Making sure those food systems are resilient and impervious to climate issues is important – because the population keeps growing. “We must come together and problem- solve how to feed people within the sustainable limitations of our planet,” continues Blacklock. “Within that frame, aquaculture becomes a leading method for ensuring nutritious protein is available for families today and in the future.”

Seafood is incredibly nutritious. It is full of vitamins and minerals that can help promote healthy growth, with large volumes of protein, vitamins D and B12, and omega-3 fatty acids. Promoting the cultivation of seafood is certainly vital, but that cultivation needs to be done in the right way. Globally, humans’ appetite for seafood and fish has had negative impacts on the marine environment. So aquaculture needs to be practised sustainably from top to bottom. This includes looking at the types of feed used, tackling waste and making production methods more sustainable.

Karen Sack

This is a particularly urgent challenge when you consider that aquaculture is as big as the global beef industry. “We’ve been fishing out our oceans on an industrial scale since the end of the Second World War,” says Karen Sack, Executive Director of the Ocean Risk and Resilience Action Alliance (ORRAA), which brings together different stakeholders worldwide to promote a sustainable and equitable blue economy. In the course of the past decade or so, says Sack, the proportion of our seafood farmed from aquaculture has outstripped that of wild-caught fish. “Part of that is because of industrial overfishing, which includes the wasteful and damaging discards that result from this,” she explains. “Part of it is because of the development and operation of agricultural techniques that have been pushed into the ocean and coastal space.”

Robert Jones

The latter can be a good thing – if done well. In terms of emissions and water use, the resource intensity of farming the oceans is more efficient than producing animal protein on land for human consumption. “When we look at the global challenge to 2050, we need to produce more food with fewer resources, and aquaculture offers that opportunity,” says Robert Jones, Global Lead for The Nature Conservancy’s Aquaculture Program. The problem is that, historically, the demand for more food more quickly has meant that industry has built many aquaculture projects to produce as much seafood as possible in as small a space and quick a time as possible – and damn the consequences. It’s a problem that’s out of sight, out of mind for many: 90 per cent of aquaculture farming occurs within Asia, meaning that many consumers do not see the harmful impact that intensive, industrial farming has on the environment.

Take, for instance, the early development in the 1950s and beyond of what the industry calls “carnivorous fin fish” – or what most of us would call salmon, tuna and other big fish that feed on other fish. That and shrimp farming was industrialised at scale, without considering the impact on broader marine life. Shrimp farming can be hugely destructive to coastal ecosystems, while any farmed-fish development can result in pollution and the overuse of antibiotics to try to prevent disease within stocks, causing wider harm.

It doesn’t need to be that way. Aquaculture is necessary not only because it can be a sustainable food source, but because it can help prevent wild fishing from negatively affecting sea populations. “We need to protect those marine resources and ensure sustainability going forward,” says Jones. “There is a maximum amount that our oceans can provide, in spite of being so vast, covering 70 per cent of our planet and providing food for billions of people.”

While doing things right isn’t always easy, it is certainly possible. “We have seen an amazing growth in potentially sustainable aquaculture,” says Sack. “If we’re looking at mitigating risks, the key is the type of farming undertaken and where it’s undertaken. We need to ensure aquaculture isn’t at an industrial scale that requires antibiotics or nutrients that could harm both the species and the ecosystems where the farms are situated.”

Current developments in sustainable aquaculture include looking at healthy seaweeds and bivalves, such as nutrient-dense oysters and mussels. These can feed people and clean ocean waters without requiring any animal feed or antibiotics. It is also important to engage with the local community around which those more intensive farming activities are based, and make sure that any benefits brought about from sustainable alternatives are ploughed back into the area, protecting mangroves and stone buffers and seagrasses that make our oceans what they are.

Coastal and marine flora aren’t only important for maintaining marine biodiversity. They are also a food source in themselves. Seaweed production more than tripled between 2000 and 2018, with more than 35 million tonnes now being produced annually worldwide. According to the World Health Organisation and the Food and Agriculture Organisation of the United States, “increased cultivation and utilisation of seaweed are expected to be important pillars of sustainable food security and a robust aquatic economy in the coming years.”

But making it a sustainable pillar of the blue economy is a challenge. Almost all seaweed production – which accounts for half of marine aquaculture production worldwide – occurs in just nine countries in Asia, where expertise to prevent disease among the crop is not always advanced. Making sure that seaweed farming takes place sustainably, harnessing the potential to diversify the submarine environment rather than bringing disease and industrial production to the seas, is critical.

The responsibility for ensuring that global aquaculture is viable lies not just with the companies doing the farming, but with those bankrolling them. Sack believes the opportunity for investing in sustainable aquaculture is just starting. “There are opportunities to make some money and do good, but you need to exercise some caution, do due diligence and look for impact funds with a firm track record, so that you don’t perpetuate a status quo that isn’t sustainable,” she says. We only have one planet, after all. And we need to make sure it stays around for all life to live on.

Richard Spinrad is a pivotal figure spanning politics and academia in the US. As Under Secretary of Commerce for Oceans and Atmosphere and head of the National Oceanic and Atmospheric Administration, the veteran oceanographer has the demanding task of guiding policy around maritime sustainability. Michael Marshall speaks with him about challenges and opportunities

“An environmental intelligence agency” is how Richard “Rick” Spinrad describes it. He is referring to the National Oceanic and Atmospheric Administration (NOAA), the US government agency (of which he is Administrator) that has responsibility for the oceans. The NOAA produces data and predictions around climate, atmospheric conditions, ocean health and protection for fisheries and marine animals – “environmental intelligence” that helps fuel sustainable economic development. One of the biggest challenges that Spinrad and NOAA face is helping to improve the way the oceans are managed so that marine resources are used sustainably. Spinrad’s goal is to maximise NOAA’s impact by ensuring its environmental intelligence reaches those who need it most, so they can respond to the challenge.

Spinrad has spent more than 40 years studying the ocean. He obtained a PhD in 1982 from Oregon State University, his early research tracking how light behaves as it travels deeper into the sea and encounters clouds of drifting sediment. Subsequently, he moved between academia and government. He held roles at universities including Oregon State and was NOAA Chief Scientist under President Obama. On Earth Day 2021, President Biden nominated Spinrad as Under Secretary of Commerce for Oceans and Atmosphere and Administrator of NOAA, putting him in charge of the agency.

Spinrad arrived at NOAA at a time when public awareness of the environmental crisis, including threats to the oceans, had become greater than ever before. “We are seeing much savvier consumers,” he says. “There’s an increased change in consumer behaviour around being green and trying to figure out products that are not doing harm to the environment.”

Alongside the shift in consumer behaviour is the intensifying political pressure to solve environmental problems. “There is a generational push right now,” says Spinrad. “The youth of the world are much better organised and much more active, in a very constructive manner, than I have ever seen in my career.” Activists including Greta Thunberg and Vanessa Nakate have driven climate change to the top of the agenda, pressuring governments to act.

On top of this, the impacts of climate change are increasingly evident. “What’s happening in the world is accelerating,” says Spinrad. “Whereas 10, 20 years ago, people tended to talk about what’s going to happen at the end of the century, now we’re starting to see impacts that are imminent and affecting market values and people’s attitudes today.”

In the United States, the result has been two landmark pieces of legislation passed by the Biden-Harris Administration: 2021’s Bipartisan Infrastructure Law (BIL) and 2022’s Inflation Reduction Act (IRA). NOAA has key roles to play in implementing both. The BIL, formally the Infrastructure Investment and Jobs Act, is a sweeping statute providing $1.2 trillion funding, $550 billion of which is new. The aim is to improve infrastructure in projects related to highways, railways, broadband access, clean water and electricity grids. The IRA is similarly ambitious. One focus is to support and boost domestic clean-energy production. Alongside such priorities, IRA provides much of the funding to support BIL programmes.

Between them, BIL and IRA are providing more than $6 billion for NOAA. This will primarily support three initiatives: better climate data, preparing coastal communities for climate change and better stewardship of fisheries. Ongoing projects include the restoration of coral reefs at Maui Nui in Hawai’i, constructing a living shoreline on Ossabaw Island in Georgia and the conservation of Cape Foulweather Headland on the Oregon coast.

It is a big advance, but Spinrad emphasises that it is a drop in the ocean compared to what is needed. “We are already seeing roughly a 10:1 proposal pressure,” he says. “The demand far exceeds the supply with respect to resourcing.” That means the money to support ocean conservation can’t just come from the government: it also has to come from the private sector.

“There is an investment opportunity,” says Spinrad. To encourage that, in July 2022 Spinrad hired Sarah Kapnick as NOAA’s new Chief Scientist. Kapnick has a background in climate science: she has studied the impacts of climate change on snowfall, the North American monsoon and tropical cyclones. She also has extensive experience of economics and finance: she has been an investment-banking analyst for Goldman Sachs, and her previous role was Managing Director at JP Morgan, with responsibility for climate and sustainability strategy for asset and wealth management.

“Science has shown how important healthy oceans are,” says Kapnick. “We know that disruption to the oceans has knock-on effects for society, including business. It affects ports, it affects supply chains. As a result, investors are increasingly interested in trying to figure out how to invest in these things.” The scale of investment needed to protect the oceans requires “an all-hands-on-deck approach,” adds Kapnick. “In financial terms, there are different layers of financing to achieve all these goals.”

It will sometimes require blended finance, in which governments, the private sector and philanthropists come together.

Philanthropists are stepping up. “We are seeing some extraordinary developments,” says Spinrad, referring to “major players” who are getting into ocean conservation. Some, such as Julie Packard, daughter of one of the founders of Hewlett Packard, have supported ocean sustainability initiatives for decades. Others, like Amazon founder Jeff Bezos, are more recent entrants. In 2020 Bezos founded the Bezos Earth Fund, which will spend $10 billion on protected areas by 2030. In July 2022 it announced $50 million of awards for marine conservation. This included $30 million to create a network of marine-protected areas off the coasts of Colombia, Costa Rica, Ecuador and Panama – linking biological hotspots over an area of 500,000 square kilometres.

Perhaps the most dramatic recent example of environmental philanthropy was the decision by Yvon Chouinard, founder of outdoor-clothing company Patagonia, to give away the company. In 2022, Chouinard announced that Patagonia would radically change its structure. It will continue to operate as a for-profit company, but its profits will go to a unique trust and non-profit organisation that will support environmental efforts, including ocean conservation. “Chouinard’s action with Patagonia would, I suspect, result in a lot of people opening their eyes to the vast proportions of what is needed for climate action,” says Spinrad.

The challenge for NOAA, as Spinrad sees it, is to get more people and companies involved in ocean sustainability – and that, he says, means working with organisations whose priorities are, on the face of it, different to one another. “The burden, if you will, is on the scientific community to get out more,” says Spinrad. NOAA has started a series of engagements and partnerships with diverse groups including the public-health community, the medical community, real-estate companies and the insurance industry. “We are learning to communicate in their terms, rather than trying to force them to speak in ours,” he says.

For example, earlier in 2023 NOAA announced a project to help support the climate needs of insurance companies. In partnership with the National Science Foundation (NSF), NOAA will create the Industry-University Cooperative Research Center (IUCRC), focused on modelling catastrophic impacts and risk assessment of climate change. The idea is to create decision-making tools for the insurance industry, enabling them to factor in risks from climate change, such as sea-level rise and increasingly intense tropical storms, when making financial decisions. NOAA is also conducting research to predict how sea-level rise will impact housing markets.

Such tools will help enable insurance companies to avoid investing in companies and infrastructure set to be threatened by climate change, or at least to charge higher premiums, thereby discouraging the building of non- resilient infrastructure. Working with such a varied group of players represents an ongoing challenge for NOAA. “We have more homework to do to understand how to better communicate these issues,” says Spinrad.

“One of our pillars is maintaining scientific integrity and having people trust us,” says Kapnick. “We don’t tell you exactly what you have to do; we provide the facts that allow the decision-makers to make those decisions.” At a time when climate change and other environmental issues are reshaping the world in which we all live, being able to forecast, based on scientific evidence, is crucial. “At NOAA, prediction is at the heart of what we do,” says Spinrad. After that, it’s up to us all.
