Greece tests eco-moorings to protect Mediterranean Posidonia seagrass.

New anchoring systems designed to protect Posidonia seagrass meadows – one of the Mediterranean’s most important yet fragile marine ecosystems – are being tested near Athens.

El turismo náutico amenaza las praderas de posidonia en el Mediterráneo

Las praderas de posidonia oceánica, esenciales para la biodiversidad y como sumidero de carbono en el Mediterráneo, se enfrentan a una grave amenaza por el turismo masivo y el fondeo incontrolado de embarcaciones. Esta planta milenaria, que crece a un centímetro al año y alberga el 20% de las especi... [Ver más]

Como sabréis las praderas de #posidonia absorben 20 veces más CO2 que los bosques. Es uno de los organismos más antiguos que tenemos, entre 140 y 65 millones de años. Se le llama también el pulmón del mar. El calentamiento climático y el turismo náutico la están extinguiendo. A pesar de que las praderas de posidonia entre Eivissa y Formentera fueron declaradas Patrimonio de la Humanidad la falta de control en los fondeos y las elevadas temperaturas están acabando con ellas.

“A new study find that Mediterranean seagrasses cut extreme water levels by 54%. Without them, sea levels near the Balearic Islands could rise 1.4 m under climate change.”

Mediterranean seagrasses provide essential coastal protection under climate change - Scientific Reports

Seagrasses are vital in coastal areas, offering crucial ecosystem services and playing a relevant role in coastal protection. The decrease in the density of Mediterranean seagrasses over recent decades, due to warming and anthropogenic stressors, may imply a serious environmental threat. Here we quantify the role of coastal impact reduction induced by seagrass presence under present and future climate. We focus in the Balearic Islands, a representative and well monitored region in the Mediterranean. Our results quantify how important the presence of seagrasses is for coastal protection. The complete loss of seagrasses would lead to an extreme water level (eTWL) increase comparable to the projected sea level rise (SLR) at the end of the century under the high end scenario of greenhouse gases emissions. Under that scenario, the eTWL could increase up to ~ 1.4 m, with 54% of that increase attributed to seagrass loss. These findings underscore the importance of seagrass conservation for coastal protection.

Posidonia, riforestati 100 metri quadri in Sicilia: il progetto di Marevivo

Secondo le stime, una volta a regime la prateria di posidonia potrà assorbire circa 8 tonnellate di anidride carbonica.
