Researchers and stakeholders are increasingly interested in evaluating soil functions their relationships with physical resilience to prevent mitigate natural anthropogenic threats. This study aims assess the effect of changing spatial support on estimating primary properties that then used map compound indicators functions. The specific objectives determine epistemic uncertainty associated estimates impact accounting for change-of-support when scaling up from point- block-resolution. area...
Mapping soil organic carbon (SOC) stock can serve as a resilience indicator for climate change. As part of the dioxide (CO2) sink, has recently become an integral global agenda to mitigate We used hyperspectral remote sensing model SOC in Sele River plain located Campania region southern Italy. To this end, spectral library (SSL) was combined with aerial image acquired AVIRIS–NG sensor mounted on Twin Otter aircraft at altitude 1433 m. The products study were four raster layers high spatial...
Abstract. Although water balance components at the catchment scale are strongly related to annual rainfall, availability of resources in Mediterranean catchments also depends on rainfall seasonality. Observed seasonal anomalies historical records fairly episodic, but an increase their frequency might exacerbate deficit or excess if rainy season shortens extends its duration, e.g., due climate change. This study evaluates sensitivity yield, evapotranspiration, and groundwater recharge changes...
Bioavailability of some major and trace elements was evaluated in 1,993 topsoil samples collected across Campania region (Southern Italy). A main focus made on Al, Ca, K, Mg, Cu, Tl since they are linked, for different reasons, to agriculture. assessed by an extraction with ammonium nitrate the data were compared pseudo-total concentration determined Aqua Regia digestion. Geochemical maps bioavailable concentrations generated using a multifractal inverse distance weighted (MIDW)...
An isotope-enabled module of Hydrus-1D was applied to a potted olive tree trace water parcels originating from 26 irrigation events in glasshouse experiment. The soil hydraulic parameters were optimized via inverse modelling by minimizing the discrepancies between observed and simulated content isotope (18O) values at three depths. model's performance validated with sap flow z-scores xylem 18O. We quantified source transit time analysing mass breakthrough curves derived virtual tracer...
Stable isotopes of hydrogen and oxygen are useful tracers for investigating the water sources exploited by plants transpiration. Recent studies focused on analysis temporal origin soil xylem water, showed that many plant species, during growing season, tend to take up originating from winter rainfall events. However, climate biophysical factors controlling still unclear. Given this background, study aims i) evaluate seasonal using so-called Seasonal Origin Index (SOI), ii) investigate...
In arid to dry sub-humid Mediterranean climate regimes, significant pressure is exerted on soil and water resources of agricultural lands, especially during the season when natural supply minimal demand for domestic use irrigation at its peak. Therefore, there concern about impacts longer-than-normal spells as well land-use/land-cover changes provision ecosystem services (ESs). To address these challenges, a Critical Zone Observatory (CZO) was established in Alento River basin, which...
Abstract. Water balance components at catchment scale are strongly related to annual rainfall amount. Nonetheless, water resources availability in Mediterranean catchments depends also on seasonality. Indeed, a high percentage of occurs between late fall and early spring feeds natural artificial reservoirs. This amount stored the mild-rainy season is used offset shortages hot-dry (between fall). Observed seasonal anomalies historical records quite episodic, but an increase their frequency...

A high percentage of the occurs between late fall early spring feeds natural artificial water reservoirs. This stored mild-rainy season is used to offset shortages hot-dry (between fall). Observed seasonal anomalies historical records are quite episodic, but an increase their frequency might exacerbate stress or excess if rainy shortens extends its duration, e.g. due...
Effective techniques for spatial data analysis are required to address the growing need develop and improve management plans at regional or continental scales. The main purpose of this research is evaluate impact change support on digital soil mapping. study based availability more than 3,300 samples collected from uppermost horizons farmlands in Campania, an administrative region southern Italy about 13,700 km2. Each sample was subjected laboratory tests determine following point-referenced...
<p>In the Upper Alento River Catchment (UARC; southern Italy), two test sites, having different physiographic and soil features, were instrumented with SoilNet wireless sensor networks controlling GS3 (METER Group, Inc. USA) capacitance sensors deployed at depths of 15 30 cm twenty locations to monitor permittivity, temperature, apparent electrical conductivity. The conversion permittivity into water content is challenging given high clay soil. Therefore, both factory...
<p>Hydrological processes along mountain hillslopes involve complex interaction between soil storage and surface subsurface flow, drainage evapotranspiration. To capture this complexity, time-lapse extensive intensive measurements are needed, potentially capable of providing spatially dense information in 3D time frequent data. end, hydro-geophysical methods (ground penetration radar, GPR, electromagnetic induction, EMI electrical resistivity tomography, ERT) based on laws...
<p>The Italian initiative WATZON (WATer mixing in the critical ZONe) is a network of instrumented sites, bringing together six pre-existing long-term research observatories monitoring different compartments Critical Zone - Earth's permeable near-surface layer from tops trees to bottom groundwater.  These cover climatic and physiographic characteristics over country, providing information climate eco-hydrologic transect connecting Mediterranean Alps.
