In tropical developing nations, seaweed farming is a fast-expanding business that has enormous promise for ensuring food security, generating money, and improving environmental health. The infrastructure of seaweed farming has developed throughout time, as it has transitioned from more conventional ways that were carried out nearshore to more contemporary advancements such as semi-automated and offshore systems. To maintain their integrity over the long term, these systems need to be able to survive weather events that are rare but extreme as well as powerful currents. The business is seeing several rising developments, including the co-cultivation of seaweed alongside other species, as well as the integration of seaweed farms alongside offshore renewable energy projects. Infrastructure for seaweed farming has the potential to enable high productivity as well as competitive harvesting and reseeding operations, which will contribute to the sustainable development of coastal towns.
