Cocoteraie dévastée par le jaunissement mortel





Les plantations de cocotiers au Ghana souffrent des effets dévastateurs d'un phytoplasme, provocant la maladie du jaunissement mortel du cocotier. Depuis 2006, un projet du Fond de Solidarité Prioritaire financé par le Ministère Français des Affaires Etrangères s'intéresse à cette problématique au Ghana.
Afin de faire le bilan de la recherche au niveau mondial sur cette maladie et d'envisager de nouvelles voies de recherche, un atelier international sur les maladies du jaunissement mortel du cocotier s'est tenu à Accra du 3 au 6 juin 2008. Cet atelier a eu une vision plus globale que le précédent séminaire tenu à Elmina en 1995 puisque la filière du cocotier en Afrique mais aussi dans le reste du monde sera abordée. Les participants viendront d'Afrique, d'Amérique Centrale, des Caraïbes, d'Asie du Sud Est et d'Europe et représenteront aussi bien le secteur de la recherche que le secteur industriel ou des producteurs.
The coconut plantations in Ghana have devastating effects from a phytoplasma, which cause the lethal yellowing disease of coconut. Since 2006, a FSP project funded by the French Ministry of Foreign Affairs is interested in this problematic facing Ghana.
In order to draw the assessment on the research worldwide on this disease and plan other new means of research, an international workshop on the lethal yellowing disease of coconut has been held in Accra from 3rd to 6th June, 2008. This workshop had a more global vision than the previous one which was held in Elmina in 1995 and this because the commodity chain of the coconut in Africa and also in the rest of the world would be tackled. The participants would come from Africa, Central America, the Caribbean, South Chorea and Eastern Europe and would represent the research sector as well as the industrial sector or the producers.
