Plus de 80% des d\u00e9chets marins sont des plastiques. Notre production de plastique ne cesse d\u2019augmenter, alors que beaucoup finit en d\u00e9chet et dans l\u2019environnement<\/strong>, \u00e0 cause d\u2019actes d\u00e9lib\u00e9r\u00e9s, de d\u00e9faillances ou de n\u00e9gligences, si bien qu\u2019\u00e0 l\u2019\u00e9chelle globale, la concentration de d\u00e9chets marins a augment\u00e9 par 100 au cours des 40 derni\u00e8res ann\u00e9es.<\/p>\n

\n

L\u2019ingestion de d\u00e9chets ou l\u2019emm\u00ealement dans les d\u00e9chets ont \u00e9t\u00e9 observ\u00e9s dans tous les taxons marins (oiseaux, mammif\u00e8res, reptiles, poissons\u2026), provoquant r\u00e9guli\u00e8rement une mort lente et douloureuse\u00a0: suffocation par \u00e9tranglement, amputation, lac\u00e9rations, obstruction ou perforation digestive, mais aussi, amoindrissement de la condition corporelle, difficult\u00e9s de d\u00e9placement ou de plong\u00e9e\u2026 Cela a un impact sur les capacit\u00e9s de reproduction et d\u2019\u00e9vitement des pr\u00e9dateurs.<\/p>\n

\n

La majorit\u00e9 des recherches sur la distribution et les impacts des d\u00e9chets portent sur les environnements marins. Pourtant, moins de 20% provient des activit\u00e9s maritimes, donc la plupart vient de la terre, v\u00e9hicul\u00e9s notamment par les fleuves et les vents. De plus, 98% des d\u00e9chets plastiques sont pi\u00e9g\u00e9s en amont, dans les environnements terrestres. Nous devons agir sur les sources\u00a0!<\/strong><\/p>\n

\n

Afin de conna\u00eetre les sources, les zones d\u2019accumulation et les impacts des d\u00e9chets pour adapter les moyens d\u2019intervention. HISA a recens\u00e9 60 publications internationales portant sur les macro-d\u00e9chets dans les cours d\u2019eau. Si la pollution est plus forte en Asie du Sud-Est, elle est aussi tr\u00e8s importante dans les fleuves europ\u00e9ens\u00a0! Les premi\u00e8res estimations en France montrent jusqu\u2019\u00e0 1000 d\u00e9chets\/heure observ\u00e9s sur la Seine\u00a0et 0,7 tonne de d\u00e9chets transport\u00e9 par le Rh\u00f4ne chaque ann\u00e9e\u2026.<\/p>\n

HISA a recens\u00e9 plus de 200 cas d\u2019interactions entre la faune et les macro-d\u00e9chets (>5 mm) des cours d\u2019eau dans la litt\u00e9rature fran\u00e7aise et internationale, chez les poissons, les amphibiens, les reptiles, les oiseaux et les mammif\u00e8res.<\/strong> Ce sont surtout des observations opportunistes, d\u2019ingestion, d\u2019emm\u00ealement, et de nombreuses esp\u00e8ces d\u2019oiseaux utilisent des d\u00e9chets pour construire leur nid. Il est important de mettre en place des \u00e9tudes d\u00e9di\u00e9es \u00e0 l\u2019impact des d\u00e9chets sur la faune dans les cours d\u2019eau et les \u00e9cosyst\u00e8mes terrestres.\u00a0<\/span><\/p>\n

C’est pourquoi HISA a r\u00e9alis\u00e9 une \u00e9tude de faisabilit\u00e9 pour la mise en \u0153uvre d\u2019une surveillance des macro-d\u00e9chets (de plus de 5 mm) dans les cours d\u2019eau\u00a0: \u00e9tats des lieux, m\u00e9thodologies, acteurs, dispositifs, initiatives…. <\/strong><\/p>\n
