01
What is the blue economy?
Supporting livelihoods while protecting the ocean
The blue economy seeks to sustain economic activity and livelihoods while keeping ocean ecosystems healthy. From fishing to tourism and energy, it asks how ocean activities can respect ecological limits and the lives of coastal communities.
The World Bank defines a blue economy approach as the sustainable use of ocean resources for economic growth, improved livelihoods and jobs while preserving ocean ecosystem health. World Bank — PROBLUE & the Blue Economy
NOAA describes blue carbon as carbon captured by the world’s ocean and coastal ecosystems. NOAA — What is blue carbon?
The blue economy addresses ocean-related economies and livelihoods broadly; blue carbon is one topic within it, linking coastal ecosystem conservation and climate action.
An ocean-based industry is not automatically sustainable. What we protect—and who gets a say—matters as much as what we grow.
Definition informed by the World Bank02 / PEOPLE
Centre livelihoods and rights
Respect the knowledge and participation of coastal residents, small-scale fishers, Indigenous Peoples and others connected to the ocean.
03 / EVIDENCE
Keep learning from evidence
Make benefits and risks visible. Update decisions through observation and dialogue.

Six themes to explore
Explore by subject
Every coastline has its own ecology, culture and livelihoods. These are starting points for better decisions, not one-size-fits-all solutions.
Food & fisheries
Fisheries and aquaculture can support food and livelihoods when resource conditions and ecosystem impacts are carefully considered.
What to check
FAO — Blue Transformation — Explore the primary sourceInitiatives & sources →Habitat impacts and contributions to local food supply and income.
Ocean energy
Offshore wind and other ocean energy technologies offer options for decarbonisation. Planning requires coordination with other ocean users.
What to check
UNEP — Sustainable Blue Economy — Explore the primary sourceEffects on wildlife, fishing and navigation, and how benefits are shared locally.
Blue carbon & ecosystems
Mangroves, salt marshes and seagrass meadows store carbon in soils while supporting biodiversity and livelihoods. Durable storage from seaweed and other pathways remains under study.
What to check
IPCC — Oceans and Coastal Ecosystems — Explore the primary sourceBlue carbon →Carbon durability and additionality, biodiversity, and community rights.
Coastal cultures
Coastal experiences and tourism can share local cultures and create income opportunities.
What to check
UNEP — Sustainable Blue Economy — Explore the primary sourceWater use, waste, ecosystem pressures and effects on residents’ quality of life.
Ocean knowledge
Connecting observations, science and local knowledge can deepen our understanding of a changing ocean.
What to check
UNESCO / IOC — UN Ocean Decade — Explore the primary sourceAccess to data, observation gaps and communication of uncertainty.
A fair ocean future
Rights, participation and the distribution of benefits are foundations for a sustainable ocean economy.
What to check
FAO — Small-Scale Fisheries Guidelines — Explore the primary sourceParticipation in decisions, distribution of benefits and costs, and inclusion of less-heard voices.

About OCEAN CONTEXT
An ocean initiative is easier to understand when you can follow its methods, evidence and limitations. OCEAN CONTEXT brings these together in Japanese and English, with introductions to the blue economy and blue carbon, practical examples and original publications from institutions and project teams.
