Migrants, abandonment and reuse of historical centers. The case of Riace in Calabria. – Italy, a migratory crossroads between Europe, Africa and Asia, has always been affected by migratory movements that have affected its regions in different ways. In recent decades, they have assumed a synergistic demo-graphic dimension between population and depopulation, which modifies the structure and composition of the population, mitigating the unstop-pable demographic decline along with the depopulation of historic cen-ters. This is possible through urban redevelopment and socio-economic revitalization paths linked to the reception of migrants. The contribution analyzes possible causes and effects of migratory processes on the Cala-brian population, using the Riace case study as a model in which the “wel-come path” has had positive results and revitalized the historical center with the return of residents and the construction of a society with high values of cultural pluralism.

Le “Geografie per l’ambiente” uniscono, nella teoria e nella prassi, i temi propri dell’attuale dibattito scientifico in materia ambientale a scala globale e locale; temi trattati in questo numero di Documenti Geografici con i principi e gli approcci metodologici di quelle scienze che si occupano di ambiente.

The hydrogeological risk in Calabria in the relocation of Cavallerizzo (Northern Calabria, Italy). – In Italy, there are many areas in hydrogeological instability and many others show clear signs that, added to neglect, poor maintenance, absence of maintenance works and unsustainable territorialization processes, turn into critical issues. Risk mitigation interventions vary depending on the exposure, but even more so on the availability of resources and the perception of risk by the communities involved. About one third of the population lives in these areas with a high hydro-geological risk, which see the relocation of settlements with the consequent abandonment of unstable historical centers among the most complex and controversial interventions. The case study concerns the relocation of the Cavallerizzo di Cerzeto hamlet in Calabria, affected by a deep gravitational movement in the area of more recent urbanization and chosen as it was rebuilt with the urban structure and neighborhood relations of the old village as a settlement for the minority ethnic-linguistic arbëreshe. 

Ten years of commissioner for the medical emergency in Calabria: dozens of dead people due to the Covid-19/ a medical crisis will become an economic crisis. – Pandemics are too complex to be left only to a medical science and must be addressed with a systems approach, necessary in the qualitative and quantitative analysis of the epidemic Covid-19 in Calabria, because of a previous crisis both of the medical and socio economic systems. Medical system is only one of the problems to reflect upon the post emergency management: it must be integrated and related with others, to understand and to manage the processes that pandemic will continuously create in different ways in the different lands. Contamination's map and epidemic effects must consider the global crisis problems and reshape them in local key. In Calabria these aspects are both managerial of the emergency and operational to the economic, political and social sectors. Only the link and the consultation among the different sectors will offer the space-tome chances to get out from the current medical crisis and to face up to next economic crisis.

Useful agricultural area income indicators, processes and development.  a reading of rural landscape and its functions. – Since the last century has grown, local and global scale, the awareness of the multifunctional role of agriculture, which adds to the productive purposes of environmental protection, landscape conservation and management of resources. Transverse to the multiple functions is the pursuit of sustainability, whose social, economic and environmental dimensions, are put at risk by increasingly binding market dynamics and agricultural policies. It seems useful, therefore, to highlight some key points of these synergies with the possible indicators, including through the presentation of case studies, aimed at understanding trends in productivity and gradual reduction of SAU.
