Saint-Barth - Sylvère Gréaux

Le conseiller territorial Sylvère Gréaux a participé pendant cinq jour à la Barbade à un séminaire sur les systèmes de gestion de l’eau.

A seminar on water management in Barbados

The territorial advisor for the Saint-Barth d'Abord group, Sylvère Gréaux, and the head of the community's environmental department, Franz Dillard, took part in a seminar on "the implementation of climate-resilient water management systems" from February 9 to 13.

Some trips to Barbados are more studious than others. For Sylvère Gréaux, territorial councilor for the Saint-Barth d'Abord group, and Franz Dillard, head of the community's environmental department, the five days (February 9-13) spent representing Saint-Barthélemy at a seminar were punctuated by intense work sessions. The purpose of their trip was to participate in discussions on a specific theme: "The implementation of water management systems resilient to climate change."
The seminar brought together specialists from the Caribbean basin, as well as French Polynesia, New Caledonia, the Falkland Islands, and elsewhere. Discussions took place during plenary sessions, scenario workshops, site visits (to desalination and water treatment plants, etc.), and case study presentations.
A crucial issue
The case studies illustrated a wide range of solutions to the challenges posed by climate change. Examples included the optimization of the wastewater treatment plant network in Montserrat, the integrated monitoring and management system implemented in Wallis and Futuna, and the joint water, sanitation, and waste management and investment options in Bermuda. A response to the influx of sargassum and the securing of the desalination system in place in the British Virgin Islands was also discussed, as were infiltration and retention basins and the drainage plan in Saint Eustatius.
Sylvère Greaux and Franz Dillard were able to exchange views with their counterparts from Saint Pierre and Miquelon, New Caledonia, Aruba, Greenland, Tristan Da Cunha, and Wallis and Futuna. "These discussions highlighted the unique situation of Saint Barthélemy in terms of its very limited freshwater resources," explains Sylvère Gréaux in his report. He emphasizes "the many similarities linked to the island context" and "Saint Barthélemy's progress in terms of production infrastructure and sustainable water resource management strategies."
For his part, Franz Dillard spoke at a round table on the subject of water supply, sanitation, and desalination. His feedback from Saint Barth resonated with the other participants.
For the island's representatives, several "high-value avenues" were identified at the end of the seminar. These included the need to strengthen desalination capacities in the face of the threat posed by Sargassum seaweed, controlling runoff by deploying retention and infiltration solutions at the plot level, and integrating green infrastructure through vegetation.
In any case, the meetings held during this seminar in Barbados provided an opportunity to assess Saint Barthélemy's progress in water management, but also to gauge the work that remains to be done to move towards an even more efficient system.
They were also of considerable importance in terms of diplomacy. Deepening regional cooperation remains a major challenge for Saint Barthélemy, particularly in an area as crucial as water resources for all island territories.
