Beyond the Blue Economy: The Rise of Integrated Circular Coastal Systems

For decades, the Blue Economy has inspired governments, industries, and researchers to rethink humanity’s relationship with the oceans. By promoting sustainable fisheries, aquaculture, maritime transport, offshore renewable energy, coastal tourism, and marine biotechnology, it has demonstrated that economic growth and environmental stewardship can coexist [1–3]. Today, the Blue Economy contributes significantly to global development while supporting millions of jobs and generating substantial economic value across coastal regions. Yet, despite its remarkable achievements, the concept is reaching a new crossroads. The environmental challenges of the twenty-first century extend well beyond the sustainable exploitation of marine resources. They now encompass water scarcity, … Continue reading

Aquaculture Using Desalination Brine: Transforming a Waste Stream into Sustainable Food Production

The rapid expansion of desalination capacity in arid and semi‑arid regions has generated an urgent need to find sustainable uses for the concentrated brine by‑product produced by seawater and brackish water desalination plants. Traditionally, brine has been treated as a waste stream, often discharged into the sea or terrestrial environments with little or no value recovery. Because most desalination technologies, especially reverse osmosis, produce brine with salinities significantly higher than natural seawater, improper disposal of this stream can lead to negative environmental impacts, including increased salinity in coastal zones, benthic ecosystem disruption, and changes in water column chemistry. However, over … Continue reading
