Seaweed Revolution: Exploring Sustainable Cultivation

The upcoming event titled “Friends of ISAM – Seaweeds for the Future?” promises to shed light on the burgeoning potential of seaweed cultivation in both environmental and economic spheres. Scheduled for July 3, 2025, at the Iziko South African Museum in Cape Town, this gathering will feature Professor Emeritus John Bolton, an expert in marine biology, who will explore the transformative ‘seaweed revolution’ that has notably taken root in Asia over the past five decades. Attendees will delve into whether such a revolution can manifest within the Western Hemisphere, particularly in South Africa, which boasts a modest yet impactful seaweed sector primarily reliant on the harvesting of natural populations. With attendance free for members and an accessible fee for non-members, the event emphasizes an inclusive approach to our coastal ecological futures.

The cultivation of seaweed offers numerous benefits, including contributions to food security, sustainable materials, and ecological restoration. As South Africa grapples with pressing environmental challenges, the discussion will also focus on creating frameworks for environmental, social, and economic sustainability within the marine sector. There is a burgeoning interest in harnessing seaweed for various applications from biofuels to bioplastics, which represents a significant opportunity for local communities and industries alike. Participants will be encouraged to consider how collaborative efforts can harness these underwater resources to foster resilience against climate change while driving innovation in aquaculture practices.
