International mobility programmes embed higher education (HE) students in a learning process in which they gain key knowledge, skills, and attitudes (KSAs), some of them crucial in pursuing the Sustainable Development Goals (SDGs). We propose an innovative theoretical framework that links such KSAs to the UNESCO’s Key Competences for Sustainability and specific SDGs. Moreover, we analysed which KSAs are addressed by institutional initiatives to support mobility students, exposing their contribution to the SDGs. Finally, we revised mobile students’ needs of institutional support on KSA’s acquisition through focus groups. Results show that the KSAs most addressed by the institutional initiatives are related to several SDGs, but mainly to SDG4 (Quality Education) and SDG8 (Decent Work and Economic Growth). Notwithstanding, additional institutional support may be needed for students to leverage their learning outcomes and transform international mobility into a key driver of the necessary social change towards the achievement of SDGs.

The present paper highlights the importance of hedgerows and enclosures in the mountains of Central Spain. Now, these landscapes have suffered profound variations in terms of agroforestry practices, especially in the Mediterranean mountains where the characteristic multifunctional has largely been lost. The article analyzes land uses changes, dynamics, and their morphological features between the first half of the 20th Century (1956) and the second decade of the present time (2019). The paper was divided into three sections. First, the identification of land uses using orthophotograph and aerial photograph; after that the info was checked with fieldwork. Eleven categories were identified according to the dominant use and land use changes and size of land parcels were taken into consideration. Second, the configuration and the information collected through the type and intensity of change in land uses made it possible to recognise and quantify their distribution and trend between these two dates. Also, the kernel density algorithm available in the Arcgis 10.5 software was used to obtain density and changes in land parcels. Finally, an overview is given of the main role that this agroforestry plays due to the social, ecological, and economic benefits that they provide for allowing sustainable development.

The activity of pollarding Fraxinus angustifolia L. is one of the most singular in the Guadarrama piedmont, Madrid. This treatment generates a patrimonial landscape of great interest and identity. The main aims of this work are to determine the surface covered by Fraxinus angustifolia L.; its conservation state and structure; the main variables that influence its distribution; and the elaboration of a typology. We start with the historical construction of these forests (from the eleventh century until the present moment). Some of them are excellent examples of pollard forests, thanks to the traditional regulations based on regional codes and byelaws and on a rational exploitation from some owners. Then, we analyse the physical determinants of this forest distribution. We establish a typology in which we consider the surface soil moisture, accompanying species, slope, morphostructural unit and type of property. Fraxinus angustifolia L. is, due to its narrow dependence of the existence of water, an indicator species of climate change and therefore vulnerable to the increase in temperatures and its consequences. Furthermore, its value as cultural heritage and the need for its conservation for its silvicultural values are highlighted.
