Study to document record amount of sargassum initiated
The Caribbean Regional Fisheries Mechanism (CRFM) has initiated a regional fact-finding study to document the record-breaking influx of Sargassum seaweed in the Caribbean Sea in 2018, and the impacts this phenomenon has been having on countries in the region since 2011.
The fact-finding survey is funded by the Japan International Cooperation Agency (JICA) that has coordinated official development assistance from Japan to CARICOM States for over two decades.
Over the past seven years, massive Sargassum influxes have been having adverse effects on national and regional economies in the Caribbean, with substantial loss of livelihoods and economic opportunities, primarily in the fisheries and tourism sectors. Large Sargassum influxes had been experienced in this region in 2011, 2014 and 2015, but it reached unprecedented levels in 2018, with more Sargassum affecting the Caribbean for a longer period of time than had previously been observed.
It is estimated that clean-up could cost the Caribbean at least $120 million in 2018. The CRFM Ministerial Council adopted the “Protocol for the Management of Extreme Accumulations of Sargassum on the Coasts of CRFM Member States” in 2016. The protocol has been guiding the drafting of national Sargassum management protocols for Grenada, St. Kitts & Nevis, St. Lucia, and St. Vincent and the Grenadines, with support from the CC4FISH project, an initiative of the United Nations Food and Agriculture Organisation (FAO).
In the coming weeks, the CRFM Secretariat will lead extensive consultations with key national stakeholders in the public and private sector, including interests in fisheries, tourism, and environment, as well as with coastal communities and other related sectors. Remote surveys and field missions in select Member States will provide a broad knowledge-base on exactly how the phenomenon has been affecting the countries.
The Sargassum phenomenon is believed to be driven by several factors, including climate change and increased sea surface temperature; change in regional winds and ocean current patterns; increased supply of Saharan dust; and nutrients from rivers, sewage and nitrogen-based fertilizers.
