Thank you, Ricardo, for recognizing the “commendable efforts” I’ve made to engage ZOFEMAT in conducting occasional beach cleaning along Half Moon Bay. But your posting above confuses the issue by implying that I do this work as a private citizen when, in fact, I do it in my capacity as Project Manager of EcoProteccion Akumal (EPA). And, frankly, promoting beach cleaning is only one of my many job responsibilities at EPA.
Although critically important, beach cleaning alone is not an effective strategy for fighting the harmful impact of Sargassum Inundation Events (SIEs). Not only are there significant downsides to excess beach removal but it does nothing to protect the reef in Half Moon Bay. This report from the US Environmental Protection Agency summarizes the harmful impact to marine ecosystems when rotting sargassum accumulates in the water:
Impact of Sargassum on Aquatic Ecosystems
The importance of addressing sargassum buildup in the water is also addressed in the sargassum management guidelines developed by the EIMAS consortium sponsored by the Mexican government. As a scientific consultant to EIMAS, I am pleased that Vecinos has posted a link to our guidelines on your website and impressed that Vecinos has actually made “a commitment to using these Mexican guidelines for Sargasso mitigation”. This is the same commitment made by EPA!
In fact, EPA is already working hard to follow the EIMAS guidelines on the Vecinos website and, under my leadership, has developed a four-pronged sargassum mitigation plan for Half Moon Bay that includes:
1. Deploying a barrier to deflect as much sargassum as possible away from Half Moon Bay.
2. DAILY beach cleaning of most (but not all) of the residual sargassum that does still reach the shore.
NOTE: EPA originally proposed that individual beachfront property owners should be responsible for cleaning their own beach concession but this approach is proving ineffective. EPA is now hopeful that we can cooperate with ZOFEMAT and Vecinos de Akumal Norte, A.C. to fund and implement a more centralized and coordinated beach cleaning plan for the entire beach along Half Moon Bay.
3. Relying on a natural sargassum drying strategy for the thin bottom layer of sargassum left on the beach.
NOTE: To avoid excess removal of sand, it is important that the bottom-most layer of sargassum NOT BE REMOVED from the beach but, instead, be spread out to dry naturally. An “Enzymatic Spray” can be applied to sargassum that’s left to dry on the beach in order to limit toxic fumes from hydrogen sulfide.
4. Transportation and disposal of sargassum through an adequate and centralized strategy, using approved disposal services and legal disposal sites.
NOTE: EPA has engaged with ZOFEMAT to provide containers for the collection of sargassum removed from the beach as well as a FREE disposal service for weekly removal of these containers.
If you disagree with EPA’s decision to build our sargassum mitigation strategy around the deflection barriers recommended in the EIMAS guidelines, I invite you to debate this or any alternative strategy that you suggest from the “Mexican guidelines for sargassum mitigation” that you mention above.
