The current sanitary crisis caused by the rapid expansion of COVID-19 offered the possibility of giving respite to dune systems and allowing their natural regeneration after the effects of storm Gloria. This storm affected the Levantine and Balearic coasts between January 21 and 23, and when some systems began to recover, intensive coastal management again compromised the integrity of dune systems. The urgency to have the systems "ready" for consumption and exploitation moves away from the concept of sustainable tourism management and does not contribute to climate change adaptation. In this work, et points out some management actions on emerged beaches that have taken place during lockdown and deconfinement. The study focus on three management actions that reveal malpractice, such as leveling and mechanical cleaning, the construction of breakwaters, and the removal of Posidonia oceanica. For this, several case studies representing some of the best-preserved beach-dune systems in Catalonia and the Balearic Islands have been chosen.
