The case study of Bitti (Sardinia): Risk perception and local best practices. – In alignment with Goal 13 of the UN 2030 Agenda, strengthening risk awareness within local communities can provide a framework for effective citizenship in managing extreme weather and climate events. In Sardinia, the community of Bitti (an inland area in the province of Nuoro, northeastern Sardinia) experienced a devastating flood in 2020. In response, local institutions and the community demonstrated resilience and implemented sound institutional practices. Following a field survey initiated through meetings with local authorities, this work presents the results of research aimed at understanding the risk perception among the municipality’s population. This insight aims to support the future implementation of participatory processes and citizen science tools designed to foster the development of communities resilient to meteorological disasters.

At the edge of the mar dulce: artificial lakes, new vocations and challenges along the Guadiana river basin. – The effects of the climate crisis on hydrographic systems, both superficial and underground, are now undeniable, with the incessant succession of prolonged droughts and catastrophic floods. The recent evolution of water governance in Extremadura, one of the European regions most affected by the effects of the climate crisis, is a relevant case study that allows stimulating reflections on today's hydro-social dynamics in the face of the worrying reduction in fresh water supplies. The Rio Guadiana basin was involved late in the process of hydraulic modernization which aimed at the renewal of Iberian agriculture. The pre-eminent irrigation purpose is associated with the production of electricity and the containment of floods. Added to this multifunctionality is the consolidation of a growing tourist presence along the banks of these mares dulces. But an arid nightmare is humiliating the dignity of Iberian hydrography.

Land use changes, human activities (deforestation, agriculture, urban sprawl, ecc.) and abnormal weather events are the common reasons of hydrological problems like floods or landslides. Neglecting the terraced landscape, for example, reduced several times the drainage capacity of the water network surface, increasing the hydrological risks. In this paper we study terraced agricultural system of two villages (Prosecco and Contovello) near Trieste. First at all, we gave a detailed description of this rural landscape. Then, we applied a GIS analysis in order to evaluate main changes in the last forty years, overlaying not homogeneous cartography sources (aerial IGM photos of the 1974 and current ortophotos). So, we identified neglecting processes and reforestation dynamics of this terraced landscape. In a restyling perspective, we identified main local tourist attractions. Finally, we hypothesized a pathway aimed at sustainable tourism.
