Comunicare il paesaggio. La fotografia come strumento di lettura delle trasformazioni del territorio

2022

Following the alterations generated by the industrialization process, guided by the continuous domination of nature in the name of progress, photography has allowed us to observe the permanence and transformations on the territory. Gregotti in his essay "La Forma Del Territorio" (1966) gives particular attention to the tools inherent in modern art, such as photography, painting and cinema. According to the architect, in fact, these tools have the ability to immediately highlight the descriptive and representative dynamics of a territory, thus becoming extremely important also in the architectural field for their anticipatory role of reality. The comparison of representations of the same pla…

Mura Pregne: una revisione dei dati archeologici e una ricostruzione virtuale del sito

2018

One of the most interesting long-term settlements in Sicily is Mura Pregne (Palermo). The site (400 m a.s.l.) is located on the northern coast of Sicily, between the last northwestern outcrops of the Madonie and the isolated relief of Monte San Calogero, in a close-up position on the Torto river valley. The earliest phases of the settlement are scarcely known and difcult to assess in their actual consistency, because a quarry has distorted the original appearance of the site. In the absence of new excavations, the purpose of this contribution is to offer a topographic description of the diferent areas, together with new archaeological considerations, based on feld survey and aerial photo an…

Assessment of Coastal Vulnerability in South Sicily

Medium-term shoreline evolution of the mediterranean coast of Andalusia (SW Spain)

2015

Coastal environment is a dynamic system in which numerous natural processes are continuously actuating and interacting among them. As a result, geomorphologic, physical and biological characteristics of coastal environments are constantly changing. Such dynamic balance is nowadays seriously threatened by the strong and increasing anthropic pressure that favors erosion processes, and the associated loss of environmental, ecologic and economic aspects. Sandy beaches are the most vulnerable environments in coastal areas. The aim of this work was to reconstruct the historical evolution of the Mediterranean coastline of Andalusia, Spain. The investigated area is about 500 km in length and includ…

Evolution des paysages Sahélines au cours des six dernières décennies dans la région de Niamey : de la disparition de la brousse tigrée à l'encroutem…

2010

In the Sahel, the rapid increase of the population during the last decades and the climate variation lead to an important environmental degradation. This work aims to measure the impacts of the human pressure on ecosystem during the six last decades. A diachronic cartography of a 100 km² area close to Niamey was done with aerial photographs (1950 and 1975) and GPS measurements (2009). Results showed that the tiger bush vegetation was completely cleared between 1950 and 2009 while the fallow decreases from 7 % to 1 %. In the sandy valley, the increase of cultivated fields from 20,7 % (1950) to 69,4 % (1975) favoured wind and water erosions which allowed surface soil crusting. Between 1975 an…

Magnetic Prospecting of Diachronic Structures (Antiquity to First World War) on the Site of the Sanctuary of Ribemont-sur-Ancre (Somme, France)

2001

International audience; The site of the sanctuary of Ribemont-sur-Ancre (Somme, France) is of major scientific interest for the knowledge of the Celtic civilization in Europe. It also presents other peculiarities: two clearly identifiable periods of occupation-the first one as early as third century BC-to the second century AD and the second one from 1914-1918. In the area disrupted through military operations, the remains of several epochs are intermingled. In order to obtain a precise knowledge of the space time organisation of each occupation, a magnetic survey was carried out. The comparison of geophysical results with the aerial photographs shot during the war allows an exact determina…
