PROBLEMATICHE AMBIENTALI E PAESAGGISTICHE CONNESSE ALL’ESPANSIONE DELLA SELVA: IL CASO DI NERVI E SANT’ILARIO (GENOVA)

Abstract

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.
