Effects of counter-urbanization on Mediterranean rural landscapes.

Context: Counter-urbanization, or the reverse migration from the city to the countryside, is a well-known demographic trend associated with rural restructuring since the 1980s. Counter-urbanization is particularly relevant in social-ecological systems with a long history of human land use, such as the Mediterranean ones. However, the extent and impacts of this phenomenon are largely unknown, particularly in this region. Objectives: We aim to review the state of the issue of counter-urbanization in the Mediterranean region. We focus on the particular determinants and outcomes of this phenomenon in Mediterranean landscapes. Methods: We conducted a bibliographic review using the Web of Science. We summarized and classified the main findings in different categories according to the socio-economic drivers of this process and its impacts on the landscape along the land sharing-sparing gradient. Results: We found 31 studies that met the criteria to be reviewed and classified them as follows: a first group of studies focused on counter-urbanization as an urban sprawl driver; a second group linked counter-urbanization to rural gentrification. These two groups point to a twofold trend of land intensification or abandonment resulting in land-sparing landscapes. A third group of studies explored the urban–rural migration motivated by economic crisis and rural areas' role as refugees that support land-sharing landscapes. A fourth group focused on multi-functional, land-sharing landscapes enhanced by rural newcomers. Conclusions: Although counter-urbanization can follow the usual path of urbanization and gentrification, it may also constitute an alternative way to reverse the current trends of rural abandonment and land-use intensification in Mediterranean landscapes. Public policies play a major role to drive this movement toward the maintenance or recovery of multifunctional landscapes, and to minimize their undesirable impacts. [ABSTRACT FROM AUTHOR]
