Las praderas de angiospermas marinas son
consideradas uno de los ecosistemas más productivos del planeta y proveedores de importantes beneficios para el bienestar del ser humano.
En Europa, estos ecosistemas han sufrido un
gran declive, estimándose que una tercera parte
del área histórica ocupada por ellos se ha perdido durante el siglo XX por impactos humanos y
causas naturales. Sin embargo, las tendencias
de pérdidas se han revertido a principios del
siglo XXI debido a la recolonización en algunos
sitios, junto con una desaceleración de las pérdidas para el conjunto de todas las especies. El
futuro de las praderas de angiospermas marinas en Europa presenta incertidumbres. Por una
parte, hay optimismo debido al aumento de la
sensibilización sobre las praderas marinas entre gestores y políticos, junto con las acciones
de conservación que han ido emergiendo en
las últimas décadas. Por otro lado, el cambio
climático es una amenaza para las praderas
marinas debido al aumento de la frecuencia y
la intensidad de tempestades y al aumento de
la temperatura, que pueden ocasionar impactos negativos sobre estos ecosistemas. Siguen
existiendo, por tanto, desafíos para asegurar el
futuro de estos valiosos ecosistemas y así mantener los beneficios que nos proporcionan.
Seagrass meadows are considered one of the most productive ecosystems on the planet and providers of important benefits for human well-being. In Europe, these ecosystems suffered a great decline and it is estimated that a third of the historical area occupied by them was lost during the 20th century due to human impacts and natural causes. However, loss trends have reversed at the beginning of the 21st century due to recolonization at some sites along with a generalised slowdown in losses for all species. The future of seagrass meadows in Europe presents uncertainties. On one hand, there is optimism due to the increase in awareness about seagrass beds among managers and politicians, together with the conservation actions that emerged in recent decades. On the other hand, climate change is a threat to seagrass beds due to the increase in the frequency and intensity of storms and the increase in temperature, which can have negative impacts on seagrass beds. Therefore, challenges remain to ensure the future of these valuable ecosystems in Europe and the benefits they provide us.
