Dynamics of the urban forest. The case of Nervi and Sant’Ilario (Genoa). – The text was developed within the PRIN project “Sylva – Ripensare la selva” and aims to analyze some landscape and environmental impacts of the rewilding process that took place in the Nervi valley. Nervi and Sant’Ilario today represent one of the “greenest” areas of the municipality of Genoa. In the past, these localities, favored by a particularly mild microclimate, were however widely exploited for agriculture on terraces and pastoralism. The abandonment process that began in the second half of the twentieth century favored the advance of the forest, interrupted only by the repeated fires that hit the valley. These phenomena have also accentuated the susceptibility to instability of the slopes, demonstrating that reforestation processes are not always positive.

Geography of the sacred: mystical literature as a source of knowledge. – The paper addresses the question whether mystical visions can offer a contribution to the knowledge of territories with regard to historical geography. The attention is limited to Christian mysticism, on which a rich literature is available, accompanied by in-depth critical analysis.
In several cases the authors provide us with significant details about the environment that is the background to episodes of sacred history, that is the geography of the Holy Land at the beginning of the 1st century. Without discussing the theological problems, the paper investigates the writings from two mystics almost a century apart, the German Anne Catherine Emmerick, a blessed nun of the 19th century and the Italian Maria Valtorta (died in 1961). These are examined in order to ascertain the validity of the geographical information contained therein and their originality with respect to the knowledge to their time.
Per me la geografia è quella dei fiumi, della graduatoria dei più lunghi, dal Po all’Adige al Tevere. E i laghi, i più grandi: Garda, Verbano, Lario, Trasimeno...La geografia umana è un’altra cosa. Eppure la parola chiave è geo. Terra. La terra madre, Gea.
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.
