The Blue Economy: Seafood’s Role in Global Food Security highlights the immense potential of aquatic resources in addressing hunger and malnutrition worldwide. Fisheries and aquaculture contribute significantly to protein intake for billions, particularly in coastal and developing regions. As climate change and overfishing threaten marine ecosystems, sustainable seafood production becomes essential for maintaining long-term food security. Innovations in mariculture, responsible fishing practices, and ecosystem-based management are reshaping how seafood is harvested and distributed. Additionally, integrating small-scale fisheries into global supply chains can enhance economic stability for fishing communities while ensuring equitable access to nutritious seafood. Balancing conservation efforts with the growing demand for aquatic foods requires strategic policies and advancements in aquaculture technologies. By prioritizing sustainability, seafood production can continue to support livelihoods, protect marine biodiversity, and strengthen food systems, making it a cornerstone of the Blue Economy.
