Wetland area are essential are for the biodiversity and the availability of water for environment. Too often, in the tropical area, these areas are confused with mangle swamp which is composed them. But there are more extensive and got many shades which made them zones too little known and studied
The Caribbean Geophysical and Numerical Research Group is proud to announce the publication of the first notebook on the water resource of Guadeloupe edited by OREC Guadeloupe (Regional Energy & Climate Observatory) named « LA RESSOURCE EN EAU ET LE CHANGEMENT CLIMATIQUE » (WATER RESOURCE AND CLIMATE CHANGE)
This document is the fruit of the collaborative work of the technical committee of the water resource of the Regional Climate Expert Group of Guadeloupe composed by ten members form University of Antilles, BRGM (French Geological and Mining Research Office), IPGP-OBSERA (Earth Physic Institute of Paris – Observatory of water and erosion in the French West Indies), INRAe (French National Institute of Agronomic Research and Environment), Flè Kawbon (Carbon Flower -Design Office-), Office de l’Eau Guadeloupe (Water Office of Guadeloupe), TCGNRG and supervised by OREC Guadeloupe (Mrs Cynthia Bonine and Amélie Belfort).
The writing of the document has been committed to Jean-François Dorville et Romain Rochette who could not go to the end of this project by lack of time.
The document is intended for institutions and the general public. It inventors the available resource, presents the climatic projections and theirs expected effects but also the possible actions to mitigate them.
The document is composed of 40 pages, 22 illustrations, 4 tables and 20 pictures. It is organized in four parts:
A presentation of climate of Guadeloupe and its main features
An inventory of the water resource, mainly those which benefit from an administrative following.
A presentation of the climate prevision, mainly those which come from C3AF up to 2080 (IPPC RCP8.5 scenario), and their expected effects on the water resource and their usage.
A presentation of levers of action, means and methods available to mitigate the future effects
The document if freely downloadable in French on that link : Cahier_de_l_eau
A long abstract will be available soon
TCGNRG hopes that it will become a reference in the Caribbean area. We still available to answer to any questions on the field (firstname.lastname@example.org)

Ability to be maintained at a certain rate or level : sustainability is an important concept developed those last thirty years when limits of our resources have been clearly identified (i.e., fossil fuel, minerals, sand, freshwater).
#JamGreenDesal presents in this fourth post how our freshwater resource is distributed and how modern life can impact it. Current situation with Climate Change and effective global warming as European countries which have experiencing higher temperature since modern methodology this summer (UK 38.5°C, France 46°C) push to figure out what will be our freshwater next month, next season and next century.
sustainability of your provision in freshwater will depend of our
usage and also the production. Green desalination can be part of the
A survey is still running to better understand relation between Jamaican and Freshwater, and how Jamaican consumed and manage freshwater. If you have 5 minutes and reside or have resided in Jamaica please help us and answer to the survey on this link
Green is not only a buzzword is also a working concept which try to fix the gap between Laws of Nature and human activity. Limited resource of earth can only push human being to better and cautiously used energy, mineral matter and organic molecules (i.e., vegetable & animal) matter.
Somes unconscious person think we will be able to find a second planet to exploit quickly, but that won’t be case before long time. It is better for us to focus on what is already available.
This third post of the Jamaican Green Desalination Project explain main feature of a Desalination plant which can be called Green.

To retrieve essential information of Freshwater and Jamaican for the Jamaican Green Desalination Project (#JamGreenDesal),
To retrieve essential information of Freshwater and Jamaican for the Jamaican Green Desalination Project (#JamGreenDesal), UWI Mona and TCGNRG have launch a public survey on Freshwater in Jamaica. The goal is to have around two thousand answers to have a significant point of view of this complex relation will be more tenuous with climate change effect. The triple economic development – environmental respect – human well being are antagonist and will ask many knowledge in order to reach balance.
invite you to answer and broadcast the link of the survey will be
open up to October 2019.
Some news : The Jamaican Green Desalination Project (#JamGreenDesal) was officially launch in its public phase. This project is a collaboration between UWI Mona and TCGNRG. Led by Zachary Williams through his MPhil. More information are available on the official webpage

1st and 2nd 2019 beaching of sargassum were observed on the
Caribbean coast of Martinique (Fort-de-France, Schoelcher). This type
of beaching has been rare since 2011 and the over-abundance of
drifting sargassum rafts in the North Atlantic and the Caribbean Sea.
Each year one or two beaching are observed on this coast from Fort-de-France to the Prêcheur. They take place only under favourable oceanographic and meteorological conditions.
The breakdown of the Trade Wind felt after the passage of a tropical wave favoured the action of the Southwest currents. Sargassum beds generally extend northward along the Caribbean coast pushed by the East wind and sea currents. This Sunday June 2nd pelagic algae were trapped by the shallow waters of creeks and bays.
days of presence, the decomposition of algae forced their collection
on the small artificialized Cove of Batelière at Schoelcher (500 on
200m), due to emanation of di-oxyde of sulphide and ammonia (SO2,
NH3). This rapid decomposition can obviously be explained by the age
of the rafts that went aground. But also by relatively high water
temperatures (27.9-28.5 ° C) which decreases dissolved oxygen
concentrations in the water of the order of 1 to 2 mg per litre and
therefore anoxic decomposition (i.e., without oxygen ).
The quality of the water is another element to take into account. Only the quality for bathing is continuously monitoring. The last map, published by the Regional Office of Health (ARS), available from (illustration 2) indicates for the beach of Batelière a ‘good’ quality. This measure is misleading because it indicates only the frequency of the presence of certain bacteria of faecal origin but not the capacity of the ecosystem to withstand anthropogenic or natural pollution.
