    This study analyzes the impact of the distribution of coconut (Cocos nucifera L.) on the beaches of the Dominican Republic and its relationship with coastal erosion and the dynamics of beach-dune systems. A total of 31 beach-dune systems were compared using 17 qualitative variables to assess the influence of palm trees planted for agricultural or touristic purposes on beach morphology, anthropic occupation, and dynamics. The results indicate that beaches with palm trees planted for touristic purposes exhibit higher compaction, slumping, and erosion, as well as lower resilience in the beach-dune system. These beaches also have a higher presence of tourist complexes, mechanical cleaning, and removal of vegetal debris, which contributes to the alteration of the beach profile and native vegetation. Palm trees can also act as wave flow accelerators, exacerbating sediment loss and increasing the risk of the palms themselves falling, which entails personal risks. It is concluded that the removal of coconut palms and comprehensive beach restoration, including the recovery of dune fronts and associated vegetation, are necessary actions to improve the stability and dynamics of Dominican coasts. Furthermore, the importance of developing planning and management strategies that promote the conservation and restoration of beach-dune systems in touristic and agricultural areas is suggested.

    This study analyzes the sediment loss associated with the removal of Syringodium filiforme berms from 10 beaches in the Dominican Republic. The results show that approximately 63.8% of the removed volume corresponds to interspersed sediment. This type of management has a continuous morphological impact, affecting the stability of the system's sediment balance.

    The study examines human influence on the evolution of beach-dune systems in the Balearic Islands, focusing on afforestation with Pinus halepensis. Historically, actions have been taken to stabilize these areas, significantly impacting the morphology and dynamics of the systems. Through a historical review and analysis of 31 such systems, it is evident that the presence of Pinus halepensis is largely associated with human interventions, significantly affecting vegetation structure and biodiversity conservation.

    The study analyses the evolution of the coastline and the hydrodynamic behaviour of the beach in the municipality of Gavà and the possibility of implementing a stabilization solution with a geotube similar to that used in Sète (France). It also collects environmental information and the characterization of the habitats, marine communities and sediments in this environment. Finally, it proposes a roadmap to improve and expand knowledge of the problems detected and propose appropriate solutions.

    This technical report is an update and expansion of the preliminary studies for the stabilization of the beaches of Gavà and Viladecans, of December 2019. This new document analyzes the entire coastal section that extends from the mouth of the Llobregat river to Ginesta port and the evolution of the shoreline from 1990 to 2020, critical areas and related problems are identified with coastal stability, and action strategies are proposed that can solve the problem that has been identified.

    The study analyzes the temporal and spatial evolution of the Platera dune system, located in Baix Empordà (Girona), using variables of use, state, and management over 16 periods between 1956 and 2016. The results obtained provide a detailed view of the Platera beach-dune system through its geoenvironmental evolution, and allow it to be directly related to parameters of use, management, and planning, with special importance to the foredune morphologies as a stabilizing element of the systems.
