They are subject to changes that greatly vary in scale, time and duration and to additionalpressures resulting from anthropogenic activities. The aim of this work was to investigate theshoreline evolution and the main environmental changes of the coastal stretch between the towns ofLicata and Gela (in the Gulf of Gela, Sicily, Italy). The methodology used in this work included theanalysis of: (i) shoreline changes over the long- and medium-term periods (1955–2019 and 1989–2019,respectively), (ii) dune system fragmentation and (iii) the impact of coastal structures (harbours andbreakwaters) on coastal evolution. The shoreline change analysis mainly showed a negative trendboth over the long- and medium-term periods, with a maximum retreat of 3.87 m/year detectedover the medium-term period down-drift of the Licata harbour. However, a few kilometres eastwardfrom the harbour, significant accretion was registered where a set of breakwaters was emplaced. TheShoreline Change Envelope (SCE) showed that the main depositional phenomena occurred duringthe decade between 1955 and 1966, whereas progressive and constant erosion was observed between1966 and 1989 in response to the increasing coastal armouring.
