“…The correlation of gully erosion severity with soil intrinsic physico-chemical factors is asserted in the literature (Nordström, 1988;Lal, 2001, Battaglia, et al, 2002Summa et al, 2007, Rienks et al, 2000Piccarreta, 2006;Singh & Prakash, 2000). Further, the state of soil dispersion and erodibility in erosion prone areas has been related to the exchangeable sodium percentage (ESP), the sodium adsorption ratio (SAR), the sodium percentage (PS) and the total amount of dissolved salts (TDS) of the surface soils (Faulkner, 2006;Piccarreta et al, 2006;Torri et al, 1994), although gullying occurs in soils that do not exceed the erosion threshold for these parameters (Rienks, 2000).…”

Water induced soil erosion, relating to improper land management, is a serious land degradation problem in Ultisols that results in rill and gully erosion. The extent of land degradation depends largely on the severity of erosion, which modifies the soil's physical and chemical properties. A detailed understanding of eroded soil properties is essential for assessment of future land management and soil-water conservation. The aim of this research is to evaluate the changes in physico-chemical and mineralogical properties of ultisols associated with gully erosion in East Tennessee. The study area is located in the southern Appalachian Valley and Ridge province, where a thick sequence of red colored clay rich soil (soil series is the Collegedale-Etowah complex) is found on dolomite and limestone bedrock. Four one-meter long soil cores and fifty-two bulk samples were collected from sites of active gully erosion (two cores) and from adjacent non-gullied soil (two cores). The physico-chemical properties assessed for each sample included clay mineralogy using X-ray diffraction (XRD), scanning electron microscopy (SEM) with energy-dispersive X-ray (EDX) methods, pH, cation exchange capacity (CEC), nitrogen, potassium, and phosphorus, particle size distribution (PSD), Atterburg limits, bulk density, moisture content, porosity, saturated hydraulic conductivity (Ks), soil erodibility factor, and swelling potential. According to the USDA, soil texture was classified as silty clay loam and silty clay. Significant differences (p<0.05) existed between eroding and non-eroding soils for the following factors: clay and silt content; porosity Ks, K; Atterberg limits, and swelling potential. Statistically significant correlations were established between clay content and Atterberg limits, bulk density, Ks, and swelling potential. Furthermore, results of X-ray diffraction indicated the presence of quartz, chlorite, illite, kaolinite, kaolinite -smectite expansive clay, hematite and ferrihydrite. Relic crystals of calcite were found in the saprolite horizon. Overall result indicated that selected physico-chemical properties can be used as an indicator of gully erosion in southern Appalachian Ultisols.

“…6). The 'badland' erosion is considered the main cause of soil degradation leading to non-compensated continuous removal of productive soils and, consequently, to desertification (Piccarreta et al, 2006a, b Piccarreta et al 2012. The 'badland' morphology affects about one third of the territory of Basilicata and occupies most of the hilly areas of the Ionic coast inland (Del Prete et al 1994).…”

The proposed geological itinerary connects a series of impressive outcrops distributed between the front and the inner portion of the Southern Apennine thrust belt. It offers the opportunity to visit some of the most interesting and bestexposed Southern Apennine geosites, inserted within landscapes typical of the different sectors of the thrust belt, in order to illustrate its geological evolution. The itinerary has been designed in such a way as to intersect different stacked tectonic units and a great variety of sedimentary successions whose age ranges from Triassic to Pleistocene. Each of the chosen geosite contains multidisciplinary geological information that may be of interest for researchers, but may be also appreciated by a general public interested in geology. In particular, the stratigraphy, the structural geology and the geomorphology are the most recurrently treated topics. Most of these outcrops extend for many hundreds or thousands of metres and include villages or mountain reliefs. Therefore, every single site can be considered as an areal geosite containing particular geological features. However, the largest geosite can also be observed in a panoramic view from suitable locations. Thus, each of these sites provides different evidence and when combined together provides an opportunity to understand the complex geological history of the Southern Apennines. The motivation for establishing this itinerary mostly resides in the great scientific interest of the chosen outcrops; this will hopefully facilitate their conservation and the development of geotourism.

“…Processes range from rill/ inter-rill erosion and gullies, to badlands, with local forms known as biancane and calanchi, and piping (Capolongo, Pennetta, Piccarreta, Fallara, & Boenzi, 2008;Clarke & Rendell, 2000;Farifteh & Soeters, 1999;Piccarreta et al, 2006a). Soil erosion processes of badlands are especially related to soil physical-chemical properties of Plio-Pleistocene deposits of the Bradanic Trough that occupy a large part of the region (De Santis, Giannossi, Medici, Summa, & Tateo, 2010;Giannossi, Medici, Summa, & Tateo, 2008;Piccarreta, Faulkner, Bentivenga, & Capolongo, 2006b;Summa & Giannossi, 2013;Summa, Tateo, Medici, & Giannossi, 2007).…”

Quantitative assessment of the sensitivity to desertification in the Bradano River basin (Basilicata, southern Italy)

Desertification is a complex environmental phenomenon that affects many regions worldwide, including the Mediterranean area. Its effects, primarily resulting from climate variations and also influenced by human-induced changes, impact upon potential regional progress due to significant economic losses, social problems and ecological damage. The aim of this study was the identification of sensitive areas to desertification at watershed scale, in the Bradano River basin (Basilicata, southern Italy). The analysis was carried out by means of the model developed within the European project MEDALUS (MEditerranean Desertification And Land USe), which identifies prone areas to desertification through the Environmentally Sensitive Areas (ESAs) index. The model parameters were implemented and processed using a GIS-based approach to evaluate climate, soil, vegetation and management system quality factors, which represent the input for the ESAs assessment. The results indicate that 35% of the study area is highly sensitive to desertification, 49% of the study area has moderate sensitivity to desertification, 12% has low sensitivity and only 4% is non-sensitive to desertification.
