3.1.2 Assessment of Soil Erosion Map
After elaborating the maps of the five aforementioned factors, namely
rainfall aggressiveness (R), soil erodibility (K), topographic factor
(LS), vegetative cover index (C), and erosion control practices factor
(P), we applied the Universal Soil Loss Equation (USLE) to derive the
results. Using the empirical and spatialized RUSLE model, which provides
an estimation of soil loss expressed in tons per hectare per year
(t/ha/year), we obtained a range of soil loss values in the Galite
archipelago. This range of values varies from 0 to 1568.8 (t/ha/year).
These results indicate the potential soil loss estimations in the
studied region, taking into account factors such as rainfall
aggressiveness, soil erodibility, topography, land management practices,
and erosion control factors. Such information can be instrumental in
assessing erosion risks and devising appropriate soil conservation
measures to prevent excessive soil losses.
This analytical approach allows us to integrate various factors
influencing soil erosion into a comprehensive model, providing insights
into the spatial distribution and magnitude of potential soil loss
across the Galite archipelago. By understanding these dynamics,
stakeholders can prioritize areas at higher risk of erosion and
implement targeted conservation strategies to mitigate soil loss
effectively.
