ABSTRACT
North Oltenia is a historic region of Romania located between Southern Carpathians and Getic Sub-Carpathians. Geology, composed largely of limestone strata with a varied in petrography and age, gives the original mark of this area. Two large limestone areas, divided by Jiu River, can be differentiated here: eastern part marked by the presence of elongated massifs orientated northeast – southwest and western part with plateaus, gorges and various karst landforms (sinkholes, uvalas, caves, etc.). The pressure induced by human activities (raw materials exploitation, limestone quarries, deforestation, traditional activities, touristic impact, waste management) leads to a negative environmental impact. The assessment methods and the Rapid Impact Assessment Matrix (RIAM) have been connected by using GIS techniques. Additionally, GIS has been used in the environmental impact assessment by combining both quantitative and qualitative geographical data. GIS and geographical assessment (GA) are very useful tools for supporting territorial decision-making process at regional and local level.
