Abstract: This paper examines the concept of the “blue economy” as a strategic approach for the sustainable use of ocean and sea resources to promote economic growth, social well-being, and environmental sustainability. Particular emphasis is placed on the link between the blue economy and food security, especially in the context of coastal cities that depend on marine resources for food and income. Key challenges are described, including pollution, climate change, overfishing, and degradation of marine ecosystems. Solutions are proposed through sustainable fishing, development of responsible aquaculture, innovative marine technologies, and maritime spatial planning. The emphasis is on implementing environmental and management innovations to ensure the long-term stability of marine ecosystems and sustainable access to seafood. The European Union plays a key role in this transition through policies such as the “Green Deal”, the “Blue Growth” strategy, and mechanisms for the greening of the maritime economy. Bulgaria is actively involved through programmes for sustainable aquaculture, maritime spatial planning, and the fight against illegal fishing, especially in the Black Sea region. The article highlights the need for an interdisciplinary and international approach based on scientific evidence and sustainable policies. The conclusion is that the blue economy is not just an economic concept, but an integrated strategy for the future of coastal societies and global food security.
