Huelva is swallowing up coastal lagoons in Doñana
Date:10/9/2009

man activity in the area escalated, the lagoons had already begun a slow process of regression and desiccation linked to the advance of dunes, coinciding with the driest phases of the climate period known as the "Little Ice Age" (from the beginning of the 14th century to halfway through the 19th century), and probably also due to the start of the current process of global warming", Sousa says.

The coastal lagoons in Doana have always been at the centre of public opinion and their conservation is of great interest. After reconstructing their evolution, the researchers confirm that the reactivation of mobile dune fronts is responsible for blocking and filling the original lagoons with sea sand. According to the experts, this could have occurred during the driest periods of the Little Ice Age in Andalusia. "If the frequency and duration of dry periods increases, together with droughts in general, the desiccation and disappearance of lagoons could become more widespread, not only in south western Europe, but also in other Mediterranean coastal ecosystems," Sousa warns.
