Les cyanobact\u00e9ries sont des bact\u00e9ries photosynth\u00e9tiques qui peuvent produire des toxines (cyanotoxines) nocives pour l’homme et les animaux. Lorsque les conditions environnementales \u2013 lumi\u00e8re, temp\u00e9rature de l\u2019eau, eaux calmes et stagnantes, et apports en nutriments important – sont favorables, elles sont capables de prolif\u00e9rer massivement, parfois en quelques jours, compromettant l’utilisation de l’eau pour l’agriculture, l’approvisionnement en eau potable, les loisirs et cr\u00e9ant g\u00e9n\u00e9ralement des probl\u00e8mes de s\u00e9curit\u00e9 et de sant\u00e9. Le contexte du changement climatique (r\u00e9duction du volume des flux d’eau, irr\u00e9gularit\u00e9 des pr\u00e9cipitations, augmentation des temp\u00e9ratures et du rayonnement solaire), et les activit\u00e9s anthropiques qui rejettent dans l\u2019environnement des quantit\u00e9s importantes de nutriments (agriculture, traitement des eaux us\u00e9es, etc.) entra\u00eenent une augmentation du risque de prolif\u00e9ration des cyanobact\u00e9ries, au point de constituer l’une des sources les plus importantes de pollution des eaux de surface dans le Sudoe. Les strat\u00e9gies actuelles de gestion de ces micro-organismes toxiques, souvent bas\u00e9es uniquement sur la rem\u00e9diation, deviennent progressivement plus co\u00fbteuses et moins efficaces en raison du changement climatique. Il en r\u00e9sulte un risque accru pour les usagers de l’eau et les \u00e9cosyst\u00e8mes aquatiques, ainsi qu’un d\u00e9fi croissant pour les gestionnaires des ressources en eau. Dans ce contexte, l’objectif principal du projet Cyan’EAU est de d\u00e9velopper des solutions r\u00e9alistes et acceptables pour les gestionnaires des ressources en eau int\u00e9grant pr\u00e9vention, d\u00e9tection pr\u00e9coce et rem\u00e9diation du risque de prolif\u00e9ration des cyanobact\u00e9ries \u00e0 l’\u00e9chelle du territoire Sudoe, afin de garantir la qualit\u00e9 de l’eau, la viabilit\u00e9 de son utilisation pour des activit\u00e9s \u00e9conomiques cl\u00e9s et la s\u00e9curit\u00e9 pour la consommation humaine. L’approche innovante de Cyan’EAU permet de privil\u00e9gier des solutions d’anticipation (pr\u00e9vention ou d\u00e9tection pr\u00e9coce), att\u00e9nuant les \u00e9pisodes de pollution et pr\u00e9servant le potentiel d’exploitation, et ouvrant ainsi l’\u00e9ventail des options disponibles aux autorit\u00e9s publiques pour une action pr\u00e9coce, \u00e9conomique et efficace.<\/p>\n","protected":false},"excerpt":{"rendered":"
