How to build a sustainable blue economy that works for people and nature

The Economist World Ocean Summit has always billed itself as a forum to focus on ocean health and sustainability. But when I first started attending the summit in 2012, industry heavyweights were largely focused on how to extract more short-term value from the ocean economy. Sustainability was still seen as a side issue — worthy, perhaps, but not essential.

When WWF sounded the alarm in 2015 about the value at risk in the ocean economy — US$2.5 trillion a year — due to destructive practices and climate change, industry and policy types took note. Suddenly, the turtle huggers were speaking the language of banks and business — risks, returns and natural capital in the form of mangroves, coral reefs and other habitats that do double duty as coast-defending infrastructure. Since then, we have relentlessly insisted that we must build a sustainable blue economy — anything less actively undermines the well-being of both people and the planet.

This week’s Economist World Ocean Summit is billed as the pre-eminent platform to debate challenges, share strategies and mobilize action to build a sustainable ocean economy. It promises opportunities to “explore the role the ocean plays in tackling climate change, enhancing biodiversity, protecting coastal communities, and restoring ecosystems.” We’re talking the talk. Now we must walk the walk.

Envisioning ocean ecosystems with people at the centre

Bringing communities into the centre of global, regional and local efforts to build a sustainable blue economy is ethically the right and just approach. It is also simply essential if practical and effective interventions to deliver conservation are to succeed. Many coastal areas and small islands in the global South come under the stewardship of communities that are struggling with food security, viable livelihoods, health, education and safety. Expecting these same communities to deliver conservation without development assistance and the necessary investment to facilitate the trade-offs required is both unwise and unfair.

Taking an equity and human rights approach to environmental issues is therefore fundamental if we are to achieve inclusive and resilient economic development. There is an ocean of opportunity for a nature-positive approach based on clean energy production and shipping, sustainable fishing and aquaculture, protecting key habitats like coral reefs, mangroves and seagrass, and creating opportunities for small-scale producers to participate fully and fairly in growing industries like seaweed farming. Marine protected areas also can be better leveraged to safeguard ocean assets, provide social dividends and underpin the blue economy.

To make the most of these opportunities, we must reject certain other activities, such as deep seabed mining, oil and gas expansion, and overfishing ever deeper and farther from shore.

But the debate about appropriate industries must not overshadow the most fundamental principle of a sustainable blue economy: people are at its centre, and not just a few, to the exclusion of the most ocean-dependent and vulnerable. We need to see the ocean as a socio-ecological system, where principles of equity, inclusiveness and transparency, as well as ecological limits and function, underscore all aspects of decision-making.


Equity also means generating quality jobs and access to financial opportunities. This should extend to the diversification of livelihoods and income, building resilience to unanticipated changes.


There should be a focus on building women’s resilience to climate change and disaster impacts through greater access to technologies and finance, diversification of livelihoods, and increased participation in women-led solutions, among others. We must also pay particular regard to vulnerable and marginalized groups, focusing on youth, the elderly, and addressing disability inclusion.

Inclusivity prioritizes community-led solutions, including the use of local, indigenous and traditional knowledge, revitalizing indigenous stewardship, and ensuring participation of vulnerable populations in decision-making process at all levels. This is particularly relevant to nature-based solutions, where traditional and indigenous approaches have considerable merit compared to many coastal hardening tactics.


When it comes to seafood, consumers are increasingly discerning and import markets are increasingly rigorous in requiring full transparency and traceability for products, with the goal of flushing illegal products, and products associated with human rights abuses, out of the system.

Bottom line: The ocean is a public domain, and fair and sustainable governance requires we all know what is occurring across 70% of the Earth’s surface.

From Talk to Action

Looking at the agenda, we clearly know the topics and issues we must tackle. When the week is over, I challenge the thousands of participants to turn a summit agenda into an action agenda, with people at the centre of the sustainable blue economy.

Building a future in which people live in harmony with nature.
