Summary: Courel mountains in Galicia, Northwest Iberian Peninsula, are characterized by embedded valleys and cramped watersheds with lithology dominated by slabs, quartzites and limestones. The recent Pleistocene cold climate led to significant glacial and periglacial processes reshaping the area. Through fieldwork, nine glacial complexes and deposits of periglacial origin have been identified on the eastern and western slopes of the mountains.

Summary: Based on a comprehensive study of the Tina Mayor estuary, a conceptual morphosedimentary model is proposed for one of the best-preserved limestone sectors of the Iberian Peninsula. The estuary is characterized by the presence of a significant proportion of quartzitic gravel fractions and the distribution of coarse fraction inputs to different geomorphological estuarine zones. The narrowing of the rocky boundary affects the outermost sector of the mouth of the estuary, influencing the flow regime. Map of estuarine morphosedimentary units is presented, including bedforms and granulometric parameters, as well as the carbonate content. A suitable classification for estuaries can be established based on tidal amplitude and mixing waters.

Summary: High spatial resolution drought projections for the Iberian Peninsula indicate that longer and more severe drought events are very likely in the future, particularly under the high-emission scenario RCP8.5. These projected changes are expected to be most significant by the end of the century.

Summary: This study aimed to understand spatial-temporal changes in coastal communities in the context of climate change in Galicia rias. The research found significant changes in seaweed communities between 1998 and 2014, with temporal beta-diversity mainly related to species loss and spatial beta-diversity significantly higher in 2014. Nitrate concentration was identified as the main driver of both temporal and spatial beta-diversity patterns.

Summary: The objective of this research is to study and characterize diatomites from the southeast of the Iberian Peninsula as natural pozzolans. Morphological and chemical characterization studies were conducted on the samples using SEM and XRF. The physical properties and technical properties of the samples were determined through various tests. The results show that the diatomites studied are pozzolanic and can be used to improve cements, mortars, and concrete.

Summary: Conservation and policy agendas have overlooked the progress in mountain grassland cover conservation by 2020, indicating a net loss in grassland extent with more areas lost than gained. Enhancing the role of protected governance regimes is important for safeguarding mountain grasslands post-2020, along with additional remote sensing research to reduce uncertainty in mapping grassland gain.

Summary: Tick-borne rickettsioses are caused by intracellular bacteria of the Rickettsia genus transmitted by hard ticks, posing a threat to both human and animal health. The Iberian Peninsula countries of Portugal and Spain have reported various rickettsial diseases, highlighting the importance of an international collaborative epidemiology surveillance network in monitoring and controlling these diseases.

Summary: Heatwave projections for the Iberian Peninsula show a general significant increase in intensity, frequency, duration, and spatial extent, particularly in the eastern-central region and on the Mediterranean coast. As climate change continues, the impacts of heatwaves are predicted to intensify further.

Summary: The upper Nysa Szalona river drainage basin in the West and Middle Sudetes exhibits diverse topography representative of the low- to medium-altitude mountain belt of Central Europe. The area is characterized by mountain ridges, massifs, uplands, and basins, with a geological history that includes pre-Variscan basement rocks, post-Variscan sedimentary cover, and volcanic rocks. The contemporary topography of the area integrates landforms resulting from rock-controlled denudation, non-uniform uplift, and glacial imprint over the late Cenozoic timescale.

Summary: The Sinai Peninsula was divided into 62 hydrological catchments, with analyses conducted using WMS and GIS tools to explore the relationships between different geomorphometric parameters. Factor analysis, Cluster Analysis, and Regression Analysis were utilized to determine key parameters and their correlations. These analyses revealed the significant correlation of catchment area with other parameters and aided in developing relationships for the construction of unit hydrograph in arid regions with limited hydrological data.

Summary: This study analyzed the evolution of a large shifting dune in the Corrubedo Natural Park using aerial images, orthophotographs, topographic surveys, and LiDAR data. The results showed that the dune front experienced two different phases, closely related to anthropic influence, highlighting the need for detailed studies and management to prevent future damage. Based on these analyses, a strategy to improve coastal and environmental management in the Corrubedo Natural Park could be designed.

Summary: The study uses high-resolution images from drones and Structure-from-Motion photogrammetric techniques, along with orthophotos and aerial LiDAR, to examine changes in rocky coastal cliffs in northwestern Galicia, Spain, from 2002 to 2018. The data suggest that cliff recession rates are increasing in the region, and the coast's plan shape is continuing to evolve, with most coastal landslides helping to transport and dispose of talus fallen from the cliffs.

Summary: In this study, a new baseline and transect method called Open-Source Digital Shoreline Analysis System (ODSAS) is proposed for dealing with irregular coastlines. ODSAS differentiates from other methods by combining raster and vector objects to determine the starting points and orientation of transects. The results obtained from ODSAS are compared with those obtained using the Digital Shoreline Analysis System (DSAS), showing similar values of coastline changes at the aggregated level but differences at the transect-by-transect level. The study emphasizes the importance of user-defined minimum resolution to reduce subjectivity in the method.

Summary: The Trevinca Massif, located in the northwestern Iberian Peninsula, has a highest elevation of 2124 m at the Trevinca peak. During the Pleistocene, it experienced extensive glacial activity, with glacier tongues reaching up to 30 km in the Bibei valley and ice thickness exceeding 500 m in some areas. Using high-resolution orthophotography and digital elevation models, paleoglaciers were reconstructed and their ice cover estimated. Four groups of moraines were identified, representing different climatic phases.
