This work aims to provide a comprehensive, wall-to-wall analysis of land use/cover changes in the continental areas of Portugal and Spain between 1990 and 2012. This overall objective is developed into two main research questions: (1) Whether differences between the extent and prevalence of changes exist between both countries and (2) which are the hotspots of change (areas where a given land use/cover transition dominates the landscape) in each country. We used Corine Land Cover in three different points in time (1990, 2000, 2012) to explore eight characteristic land cover transitions and carried out a cluster analysis at LAU2 level (municipalities in Spain, parishes in Portugal) that allowed to identify the areas in which each transition was dominant. The main findings include the decline of agricultural area and the increase of urbanized and artificial covers in both countries, but different trends followed by forest cover, with an increase in Spain and a decrease in Portugal. At the same time, the spatial analysis provided an overview of the main gradients of change related to tensions between agricultural intensification–extensification, on the one hand, and deforestation–afforestation, on the other.

Resilience is not a particularly novel concept, but it has recently become frequently used as a measurement indicator of adaptation capacity under different approaches depending on the field of study. Ideally, for example, forest ecosystems would be resilient to wildfires, one of the most serious types of perturbation they are subjected to. In areas such as the northwest of Spain, a region with one of the most severe records of wildfire occurrence in western Europe, resilience indicators should be related with changes in land planning aimed to minimize the effects of forest fires. This article aimed to analyze the fire resilience strategies of a selected group of forest communities in northwest Spain. More specifically, the perceived risk of wildfires was compared with the actual record of fire events in these communities and the presence or absence of adaptive changes in management practices to reduce risk and improve recovery capacity. A mixed quantitative–qualitative approach was used to gather information about good practices, innovative solutions, and major obstacles for forest fire resilience in Galician common lands. The results suggest that while there is no single form of successful management, a key characteristic of resilient communities is the integration of fire as a management tool.

This work analyzes the determinants associated with main land use/cover changes in the Iberian Peninsula during the 1990–2012 period using a decision tree model. Our main objective is to identify broad-scale patterns that associate the characteristics of geographic areas with the dominant land use/cover change process based on CORINE Land Cover (Coordination of Information on the Environment) and defined in a previously published work. Biophysical, structural and socioeconomic variables were considered as potentially explanatory of the dominant change process at municipal scale. The resulting model allowed identification of a common pattern in Portugal and Spain (urbanization being highly associated to areas already densely populated in the previous period), but also some diverging ones. In particular, dominant trends in Portuguese territory appear to be highly determined by wildfire occurrence. In contrast, Spanish municipalities showed more diverse patterns, usually associated to biophysical determinants like average forest productivity or average terrain slope.
