Soil erosion changes in Portugal through the sediment delivery ratio model
| Resumo: | Soils provide relevant ecosystem functions, important to the preservation of mankind. However, soil degradation, and particularly soil erosion, is endangering the maintenance and existence of these services. This study aims to analyze the spatiotemporal distribution of soil erosion by understanding the spatial patterns ofthe sediment retention in mainland Portugal with the support of Corine Land Cover maps from 1990 to 2018. Results highlight the sediment retention levels across administrative boundaries, showing which districts are more susceptible to soil erosion processes. Results further indicate that Coimbra, Leiria and Braga, are facing high levels of potential soil erosion. These findings can be useful to support strategies for more efficient landscape planning regarding soil erosion negative consequences mitigation |
