What does it mean to defend the ocean — and who gets to define it?
The ocean is the world’s largest shared space, but the people responsible for securing, governing, exploiting, and protecting it rarely operate within the same framework.
Naval planners think in terms of deterrence, sovereignty, and critical infrastructure. Scientists focus on ecosystems and resource management. Industry sees operational resilience and commercial risk. Fisheries organisations worry about livelihoods and food security. International institutions approach the ocean through governance and law.
All of these actors operate within the same maritime system — yet they rarely share a common language, and even more rarely share the same conversation.
Defending Blue was created in response to that gap.
A platform built around questions
Defending Blue is an independent platform exploring the intersection of maritime security, ocean governance, sustainability, industry, and strategy.
It starts from a simple idea: every actor operating in the maritime domain is defending something. The problem is not a lack of engagement, but the fact that these communities often define “defence” differently — and therefore struggle to coordinate effectively.
Rather than advocating for a single policy position, Defending Blue exists to create the conditions for better questions to be asked — and for the right people to be part of the conversation when those questions matter.
The platform brings together voices that do not usually share the same space: naval officers, coast guards, industry leaders, researchers, policy-makers, investors, technologists, and civil society organisations.
From conversation to consequence
Each Defending Blue podcast episode is built around a single analytical question related to the Blue Nexus — the increasingly interconnected space linking maritime security, governance, sustainability, infrastructure, technology, and economic resilience.
Every conversation produces a Curated Briefing: a short, policy-oriented document translating discussion into actionable insight.
Together, the podcast, briefings, website, and newsletter form a growing analytical resource designed to help maritime actors navigate the complexity of the modern ocean environment more coherently.
Independent by design
Defending Blue is geographically neutral and editorially independent.
The platform deliberately includes perspectives from the Indo-Pacific, Latin America, Africa, Europe, North America, and island states alongside established maritime powers. Maritime challenges are global, and the conversation surrounding them cannot remain confined to a single institutional or geographic worldview.
Partnerships help sustain the platform, but they do not determine its conclusions. Editorial independence remains a core operating principle because the credibility of the conversation depends on it.
Because no one defends the ocean alone.
Defending Blue was founded by Alix Valenti, a journalist and moderator specialising in maritime security, defence, and ocean-related strategic issues.
Through interviews, conferences, and cross-sector dialogue, her work has increasingly focused on the deep entanglement between maritime security, ocean governance, industry, and sustainability — communities that often operate in the same waters while struggling to speak the same language.
Defending Blue was created as a response to that gap: a platform designed to connect perspectives that rarely share the same conversation, and to explore what it means to defend the ocean in an increasingly interconnected maritime environment.
