First Look at the Future of Sargassum Control: Sargassum Harvesters for San Pedro

On Friday, April 11, 2025, a clear and breezy morning, I joined community members, officials, and conservation leaders on the beach in San Pedro to witness the launch of the Sargassum Relief Project — a bold new initiative led by the Hol Chan Marine Reserve and the Ministry of Blue Economy and Marine Conservation. At the center of the event were two large, gleaming sargassum harvesters, now officially a part of San Pedro’s growing arsenal against the relentless invasion of seaweed that has been impacting our shores for over a decade.

As someone who walks these beaches regularly and sees the toll that sargassum takes on our coastline, tourism, and marine life, this launch felt more than symbolic. It was a sign of serious action – strategic, forward-thinking, and finally harnessing technology to tackle what has become a yearly concern.

Hol Chan’s Executive Director, Ian Pou, reminded us why we were all there. He spoke passionately about the duality of sargassum – its ecological importance in open waters, and its destructive impact when it piles up on our beaches. He called the project both a challenge and an opportunity, and I couldn’t help but agree. Pou emphasized that this was more than just a cleanup initiative – it was Hol Chan accepting a civil responsibility to protect not just the environment, but also the livelihoods connected to it.

What made the event even more memorable for me personally was the opportunity to actually board one of the new harvesters and witness how it operates. I stepped onto the vessel as it gently bobbed just off the reef, and within moments we were moving through a patch of drifting sargassum. The machinery was impressive – quiet, deliberate, and precise. It swept up the floating masses way before they could reach the shoreline, where the sargassum would otherwise rot, smell, and choke off sea grass and marine life. From that vantage point, I could see how this equipment is not just a tool, it’s a game changer.

Minister Andre Perez, our area representative and the Minister of Blue Economy, described the initiative as part of a regional battle. He reminded us that sargassum isn’t just a San Pedro or Belize issue – it affects the entire Caribbean and the Yucatán Peninsula. But his message was clear: rather than relying on brute force, we need innovation. He spoke of satellite technology, drone surveillance, and targeted collection zones. I left with the sense that this wasn’t a one-off effort, but the beginning of a smarter, more adaptive approach.

What struck me most during the speeches was the emphasis on partnership. The Social Security Board, represented by Acting CEO Jerome Palma, invested in this project not only for environmental reasons but also for the long-term economic sustainability it represents. As Palma said, this was an investment in a healthier Belize – one where tourism can thrive, coastal ecosystems can recover, and workers no longer have to spend their days shoveling seaweed in the heat.

The sargassum harvesters themselves came from as far as China, and Perez noted that modifications were needed to make them suitable for our unique reef-protected waters. The nearly $2 million investment is already proving to be worthwhile. The machines can operate in extremely shallow water, which is essential for our coast. Minister Perez even floated the possibility of a fleet of harvesters in the future — not just for Ambergris Caye, but for the entire coast of Belize.

For me, this experience was about more than witnessing a launch — it was about seeing hope in action. We’ve been talking about sargassum for years. We’ve seen resorts overwhelmed, workers pulled from other sectors, and local governments scrambling to keep up. But now, with innovation, coordination, and vision, we have a real plan.

As the harvester pulled back to shore and I stepped off, I felt something I hadn’t felt in a long time when it came to this issue – optimism. The road ahead will require collaboration, continued funding, and adaptability, but today, we took a giant step in the right direction. San Pedro deserves clean shores, vibrant marine life, and a blue economy that works for everyone. This project just might be the beginning of that brighter, cleaner future.
