Special Issue Information

Dear Colleagues,

Mediterranean-climate regions are located across various regions of the globe and account for about 2% of the Earth’s surface. These regions are typically characterized by a unique climatic regime with wet winters and warm, dry summers. Presenting an extensive biodiversity, they are internationally recognized as one of the most sensitive regions to the impacts of climate change and anthropic actions.
In such contexts, soil erosion offers a critical perspective of future effects as it is associated with a general degradation of the environment and depletion of soil nutrients due to the anthropic impacts of agricultural exploitation. In many Mediterranean areas, the interactions between climate and human activities have already led to short- and mid-term unsustainability.
Although total rainfall is generally decreasing in these regions, the intensity of extreme events is expected to increase, leading to an alarming potential for climate change to impact soil erosion and land degradation. Furthermore, many factors related to land use contribute to the aggravation of the phenomenon, such as changes in land use and erosive crops increasing soil loss.
This Special Issue aims to collect and highlight developments in the detection, monitoring, and modelling of soil erosion and land degradation in Mediterranean areas, with special attention on long-term perspectives. These findings are thought to support and be useful for the implementation of ecosystem services and for understanding, planning, solving, and mitigating soil erosion in these fragile ecosystems and agricultural environments.

Soil aggregate stability is an ideal integrative soil quality indicator, but little is known about the relevance of such an indicator with soil depth for salt-affected soils. The objective of this study was to determine soil aggregate stability and identify preponderant aggregation factors, both in topsoil and subsoil horizons in salt-affected conditions. We conducted field investigations by describing soil profiles in pedological pits and by collecting soil samples from different field units. Soils were sampled within different soil horizon types, from superficial tilled organo-mineral horizons to mineral horizons. For all soil samples, we determined the mean weight diameter (MWD) as an indicator of soil aggregate stability and also determined associated physical and chemical properties in some samples. The measured MWD value from 0.28 mm to 1.10 mm could be categorised as unstable, with MWD values and variability decreasing drastically from the topsoil to the deepest mineral horizons. Analysis of MWD in relation to physical and chemical properties suggested that the variability in the MWD value of A-horizons was influenced by both clay fraction abundance and soil organic carbon (SOC) content and the nature of the agricultural practices, while at deeper B-horizons, the decrease in SOC content and the variability in other soil properties with soil depth could be used to explain the overall low aggregate stability. In this study, investigations of soil pits coupled with measurements of soil aggregate stability indicated that it could be possible to restore soil structure quality by limiting deep soil profile compaction in order to improve salt leaching and exportation.

Biancana badlands are peculiar landforms in the Basilicata region of Italy resulting from the local combination of geological, geomorphological, and climatic settings. The evolution of badlands mainly depends on slope erosion, which is controlled by the angle, exposure, and vegetation of the slope and its interactions with insolation, rain, and wind. Multi-temporal, detailed, high-resolution surveys have led researchers to assess changes in slopes to investigate the spatial distributions of erosion and deposition and the influence of wind-driven rain (WDR). A comparison between two terrestrial laser scanner (TLS) point clouds surveyed during 2006 and 2016 fieldwork showed that the study area suffers from intense erosion that is not spatially uniform on all sides of biancane. By combining slope and exposure data and the cloud of difference (CoD), derived from a 3D model, we showed that all the steepest southern sides of biancane suffered the most intense erosion. Because splash and sheet erosion triggers sediment displacement, the analysis was also focused on the intensity and direction of WDR. We performed a real field experiment analysing erosion rates over 10 years in relation to daily and hourly wind data (direction and speed), and we found that frequent winds of moderate force, combined with moderate to heavy rainfall, contributed to the observed increase in soil erosion when combined with the insolation effect. Our results show how all the considered factors interact in a complex pattern to control the spatial distribution of erosion. Full article
