SARGASSUM BLOOMING IN THE CARIBBEAN: HUMAN AND ENVIRONMENT INTERACTIONS
Julia Fraga & Florence Ménez
CINVESTAV Mérida & Université des Antilles


In the last five years sargassum blooming in the widder Caribbean represents a really socio-environmental problem. In 2011 Sargassum abruptly changed the seascapes of the Caribbean. The origen and impacts are really unknows. Experts said that the brow pelagic macroalgue comes from a new region (NEER) front Brasil and Western Africa and not really come from Sargasso Sea in the BermudasTriangle
Recently sargassum patterns were relatively easy to predict but not easy to manage (collect, transport and valorise). Mexico and French Caribbean were really impacted ecologically, sanitary, economically.The Sargassum tend to focus in lost revenue from tourism, fishing and create a sanitary crisis.Sargassum deposits grew to several meters thick obscuringthe sand and turning nearshore marine waters into seething sargassum nightmare or ¿probably opportunities for the coastal actors?

The wider caribbean included 26 countries with 44,303, 577 of population with a high dependency in tourism and fishing activities. Represent a 9% for the Gross National Economy of te region. Represent a hot spot marine biodiversity in the region but now confront the sargassum blooming. With a simplistic hyphotesis probably the region lost more million of dollars for the prevention and mitigation of the sargassum blooming than the reconstruction of areas after the impacts of hurricanes. Hurricanes in a temporal scale pass not almost 36 heuresbatting the coastal infrastructures instead Sargassum floting and sargassum alongshore washes occurred between four and eight months since 2011. Sargassum in the beaches is a titanic activity for the states and tourism resorts expanded in the caribbean littoral. Sargassum arrival with fish, contaminants, bacteria, virus, plastics is really an environmental impacts almost impossible to quantify.

In the region fishing represent only a 1% of the Gross National Product but million of people from rural areas migrate seasonality to the fishing sector for to survival.Coral reefs in the caribbean with this sargassum blooming impact the marine fauna and flora. By the side of leisure industries, and the employees of the tourism industry, mainly seasonal employeescombining rural and coastal activities are in serious problems.

What’s the experience of Sargassum blooming in the Widder Caribbean? What’s the lessons learned in socioecological impacts? What’s the stakeholders responses, mainly tourism and fishing sector?There are a sanitary problems with the collectors of sargassum? How science, policy and society confront the Sargassum crisis and How does confronted by local population in the Caribbean?
The panel highlights to evaluate the differents mechanisms that institutions and socioeconomic actors confront with sargassum blooming. At same time, the panel want to identify future researchtaking into account a Ecosytem Based Management (EBM) perspective for the Oceans. Sargassum Blooming in French Caribbean : Building and Overcoming Crisis and Socio-environmental Dimension of the Sargassum blooming in Mexican Caribbean are compromised in this panel.
