The Blue Economy depends on fragile marine ecosystems, which provide essential ecosystem services such as clean water, food supply, climate regulation, and coastal protection. However, the various marine sectors often rely on the same ecosystem services while simultaneously impacting other services that are vital for different sectors.

Blue Economy – “All economic activities related to oceans, seas, and coasts. It covers both established sectors such as fisheries, tourism, and maritime transport, as well as emerging industries like offshore renewable energy, aquaculture, blue biotechnology, and seabed mining.” Source: The EU Blue Economy Report 2021.

clean water, food supply, climate regulation, and coastal protection. However, the various marine sectors often rely on the same ecosystem services while simultaneously impacting other services that are vital for different sectors.
For example, aquaculture can enhance food security but may lead to nutrient pollution, which affects water quality and impacts tourism or fisheries. Similarly, offshore energy farms help reduce greenhouse gas emissions but can alter marine habitats, disrupting ecosystems that support fishing or recreational activities. These interactions highlight the trade-offs between sectors and the need for careful management.
Why Ecosystem Services Matter?
Ecosystem services are the benefits we get from nature that support our lives and well-being. The ocean, in particular, provides vital ecosystem services that people rely on, including, for example:
– Cultural services: Recreation and tourism.
– Provisioning services: Seafood, renewable energy, and resources.
– Regulating services: Climate regulation and water quality.
So, how can we promote economic growth to meet human needs while ensuring conservation?
For truly sustainable growth, it is essential to adopt a holistic management approach that recognizes the interconnected nature of blue sectors and their impacts on marine ecosystem health. Such an approach safeguards the ability of ecosystems to continue providing services that support both human well-being and ocean conservation. Processes and tools like Marine Spatial Planning (MSP) and Marine Protected Areas (MPAs) play a crucial role in this effort. They help regulate the use of marine space, balance conservation with economic activities, and mitigate conflicts among sectors. By minimizing adverse impacts and promoting good management practices, these tools ensure the sustainability of marine ecosystems and the essential services they provide.
To support the responsible integration of economic activities into marine environments, the MSP4BIO project has developed a Guideline for the strategic and spatial measures for the nature-inclusive operation of blue economy sectors – ESE 3. This work has been summarised into Sectoral Sheets for five key blue economy sectors: Aquaculture, Fisheries, Marine Non-Living Resources, Renewable Energy, and Tourism.
These sheets provide:
- Sector-specific activities and their impacts on ecosystem services.
- Good Management Practices (GMPs): actionable solutions to mitigate environmental impacts.
- Visual tools, like Sankey diagrams, to illustrate the flow of sector pressures and their effect on ecosystems.
By using these resources, stakeholders can better understand trade-offs, resolve user-user conflicts, and foster user-environment harmony, ensuring a more sustainable and integrated approach to blue economy development.
A sustainable blue economy is a necessity. With careful planning and responsible management, we can ensure the ocean remains a source of life, livelihood, and inspiration for generations to come.
