The geological layout of Landscape Master Plan: an example from Liguria (Italy)

After more than 25 years since the first studies, the Landscape Master Plan of Liguria has contributed to maintaining the cultural and natural landscape. The current plan is made by three descriptive layouts and related regulations: the settlement and botanical settings represent the features of the landscape linked to buildings and vegetation. The geomorphological layout shows only the regulations, without any reference to Earth surface processes and landforms. This research suggests a methodology aiming at providing the plan with an engineering geologic suitable layout with the other settings. We propose eight geomorphological landscape units: all of them are connected with Earth surface dynamic factors, including man-made landforms and geodiversity values. A double key to the interpretation of this geo-map is suggested. The capital letters corresponding to regulations are maintained; we have inserted a new label linked to the geomorphological landscape unit. This updating may be integrated in the review processes of the Landscape Master Plan already started by Regional Authority.
