A critical view of the restoration of dune systems in the Balearic Islands (2000-2017)

In recent decades, different coastal management techniques have been used along the Spanish coast in order to restore, maintain and protect beach-dune systems. These techniques are based on the artificial emulation of natural processes that favour the recovery of the system, while others have been based on the setting up of services that avoid the frequenting and trampling of the dune systems. The lack of geomorphological criteria in some management activities carried out in the Balearic Islands, has caused and aggravated erosion on the systems that were supposed to be recovered, or they have artificially established those dynamic systems. This paper illustrates some techniques applied without geomorphological criteria on dune systems.
