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.

The study analyzes the influx and mobility of recreational and sports boats on the beaches and coves of the Baix Empordà coastline, as well as user behavior and the impact on 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.

Analysis of the diversity and complexity of the coastal landscape, resulting from the interaction between natural and human processes.

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.

The Map for the Prevention of Geological Risks is a document that represents the geological hazard of the territory at a scale of 1:25,000. It is a multi-hazard map, which offers an overview of the hazards identified in the territory. The territory is zoned, for each hazard considered, into high, medium and low hazard, and is represented according to traffic lights. The symbology used allows the type of phenomenon causing the hazard to be identified, while the phenomena and indicators of this hazard are represented.

This data mainly includes: a map of sea surface temperature recorded the previous day in Catalonia, which is updated daily; a chart showing the daily average sea surface temperature in the Mediterranean, along with the annual trends from recent years and historical records from 1982 to 2019; and finally, another real-time map indicating the areas currently experiencing marine heatwaves. On the same website where this data is presented, more detailed information about this phenomenon can also be found.

Location and characteristics of the geotechnical surveys of the subsoil carried out (boreholes, penetrometers and test pits).

The boreholes database is an inventory of subsurface data in Catalonia through the collection of available geological and geotechnical survey information. The surveys are classified into three groups: surveys, penetrometers and trial pits.

Synthesis of the geological constitution of Catalonia through the cartographic representation of lithostratigraphic geological units, major structural elements (unconformities, faults and folds) and types of contact between units. The situation of the soundings carried out for the exploration of hydrocarbons is also included.
