The Challenge for Enhancing Nationwide Sargassum Administration Capacities within the Caribbean

This mission goals to assist the enhancement of the nationwide capability for the administration of sargassum inundations by offering 5 (5) small island growing states within the Japanese Caribbean with tools, experience, and technical data to gather, take away, transport, and eliminate sargassum collected on shore and/or within the nearshore.

Since 2011, huge, episodic influxes of floating sargassum seaweed inundating Caribbean shorelines have manifested as an emergent coastal hazard and a recurring exterior shock to the techniques of Caribbean Small Island Growing States (SIDS).  In response to the 2021 UNEP Sargassum White Paper, Caribbean territories can obtain as a lot as 100 metric tonnes of sargassum per kilometre of seashore per day throughout an inundation occasion. These influxes result in inundations of shorelines, leading to financial losses throughout varied sectors whereas additionally creating social and well being points for a lot of coastal communities. As well as, coastal ecosystems have been negatively impacted by each the contemporary and decaying seaweed. The challenges is compounded by the truth that timing and portions of inundations are troublesome to foretell. This phenomenon, when paired with the hostile results of local weather change – similar to sea degree rise, ocean acidification, and different coastal hazards, will increase the stress on weak coastal zones.  SIDS are particularly weak to such exterior shocks, and sometimes wrestle with the capability to mount a response.

The mission goals to assist the enhancement of the nationwide capability for the administration of sargassum seaweed by offering 5 (5) nations within the Caribbean with tools, experience, and technical data to gather, take away, transport, and eliminate collected/stranded sargassum to mitigate the reoccurring risk posed. This initiative will increase marine and nearshore coastal conservation efforts, assist built-in coastal administration actions, and mitigate damaging impacts on sectors similar to fisheries, public well being, and tourism with consideration for together with gender dimensions the place doable.

The mission will obtain this primarily via the acquisition of sargassum elimination and assortment equipment, which might be complemented and supported by related gender responsive coaching and capability improvement programmes. Supporting actions will embrace growing capability in scientific monitoring of sargassum inundation portions, improvement of sargassum assortment and administration plans, coaching in elimination, transport and disposal of sargassum, and facilitation of regional dialogues, communications, sharing experiences and classes learnt.

The mission additionally seeks to establish downstream alternatives for MSME’s on using freshly harvested sargassum collected previous to decomposition.  To this finish, the mission will search to leverage partnerships with the UNDP Blue Accelerator Lab and different strategic companions within the area.  

Actual Speak or Hype: Sargassum Symposium Recap

Because the emergence of sargassum inundations as main exterior shocks affecting the Caribbean, there was important curiosity and energetic analysis in utilizing or ‘valorising’ sargassum. This consists of each tutorial analysis and business-oriented analysis and improvement. Most the work focuses on the processes for changing the sargassum, as a uncooked materials, into commercially viable merchandise.  There’s some indication that sargassum may very well be used as a uncooked materials in a variety of merchandise, together with amongst others, fertilizer, biofuels, constructing supplies and cleaning soap.  This very dynamic ‘sargassum house’ can also be replete with varied actors selling a variety of choices together with services and products marketed as options to the sargassum downside.  There’s a probably receptive market, with governments and stakeholders eager for options.  Nevertheless, up to now, curiosity and choices haven’t translated into tangible outcomes.  For these attempting to know why, the dynamic nature of the house turns into a part of the problem – data overload, noise and hype can obscure actuality.  

With this panel, we intention to deliver some ‘actual discuss’ to chop via the hype and noise.  We contend that the true query is just not ‘can we discover makes use of for sargassum?’ – as a result of it looks like we will – however relatively ‘can we implement using sargassum at a big sufficient scale to alleviate the issue?’  We take a look at the difficulty of scale and unpack the important thing components within the feasibility of upscaling. 

Catch the recording to affix our panel of specialists from throughout a number of disciplines for a centered and illuminating dialogue on this central query in addressing the issue of sargassum inundations. Thanks to Sen. Crystal Drakes, Mark Hill, and Prof. Oxenford (CERMES), together with our personal Dr. Mohammad Nagdee and Karima Degia for his or her panel contributions.  

Congratulations to UWI-CERMES on an thrilling and informative 3rd Sargassum Symposium, and plenty of thanks in your assist and the chance to collaborate on this panel dialogue.

Managing Sargassum Shoreline Inundations: A Toolbox

UWI-CERMES is thrilled to announce the discharge of Managing Sargassum Shoreline Inundations: A Toolbox, Quantity 5 within the SargAdapt Good Follow Information Collection, for public sector managers and personal sector companies straight managing the sargassum downside. We intention to offer a balanced mixture of technical and sensible steering that can assist you establish the obtainable instruments and assets, consider the important thing issues for operational planning, and choose tools for clearing and harvesting in the event you take that route. This launch builds on the lately concluded third Sargassum Symposium held in March. Many thanks the SargAdapt Challenge Group and contributing authors, together with from the UNDP-Japan Sargassum Challenge. Sargassum administration is an evolving follow, and we welcome your suggestions and enter to replace and enhance future steering merchandise.
