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 analyzes changes in the forest landscape of the Costa Brava over the past century through the comparison of historical and contemporary photographs. The results show a significant increase in forest cover, with the recovery of pine and oak forests, while agricultural areas have declined. This suggests a shift in land use and in the tourist perception of the landscape.

This article updates the floristic knowledge of the species that colonize the beaches and dunes of the Catalan coast. The study identifies typical species of these habitats, as well as those restricted to dunes. A total of 87 dune systems were sampled, identifying 224 species, of which 87 are considered typical of beach and dune habitats, and 34 are exclusive to these environments. The presence of exotic species reflects human impact on these ecosystems.

The study focuses on floristic diversity and impacts on dune systems along the Catalan coast. Twenty-one dune-restricted plant species were identified as indicators of ecological integrity. A new index was applied to measure species diversity relative to total site biodiversity. Results indicate that dunes with less human activity retain more native species.

The patterns of use and frequentation of beaches are a useful tool in coastal management and planning. The aim of this article is to apply the methodology for the analysis of physical carrying capacity in 16 beaches of the island of Menorca, based on the values in m²/user recommended in 2000. A multi-temporal analysis of the evolution of the beaches is carried out using qualitative variables that allow obtaining the trends of the beaches with parameters that analyze their management and occupation (2000-2017). The results obtained show that the beaches have acceptable carrying capacities and that environmental management, their publicity, and the services provided condition their spatio-temporal evolution. The methodology allows establishing future scenarios through the use of the analyzed variables.

This study evaluates the geomorphological state of 12 beach-dune systems over time, classifying them into four stages according to their degree of degradation: 1- systems in a natural state (two beaches), 2- highly altered or disappeared dune systems (three beaches), 3- dune systems in recovery process (five beaches), and 4- stabilized dune systems (two beaches).

This study analyzes the changes in the dune landscape of Catalonia as a result of urban and tourism pressure and describes the main dune systems that still persist, highlighting their causes of degradation.

This study analyzes geohistorical sources to understand coastal management of Sant Pere Pescador beach in the Gulf of Roses.

The study analyzes the floristic composition and vegetation structure in the dune spaces of the Llobregat Delta, highlighting the changes caused by natural and anthropic factors. The impacts of exotic species, especially invasive ones, are also discussed.
