| Popis: | Monitoring has played a key role in understanding the rates, extent and frequency of erosion on agricultural land and this includes projects in Switzerland, Germany and the UK. In this case we focus on highly erodible soils in the Rother valley, West Sussex, southern England on which grow a range of arable crops throughout the year. Erosion rates and extent are high, particularly in response to exceptionally wet periods in the early winter. In the monitored period, rates on summer crops were relatively low due to an absence of intense summer storms. In the years 2015‐20, erosion was localised to where limited areas of bare ground coincided with heavy winter rainfall. Issues of river pollution, associated with excessive sedimentation, off‐site flooding and a high degree of connectivity between arable fields and the river, are of increasing concern. Mitigation measures need to be expanded to protect freshwater systems and properties. This study has implications for similar programmes in intensely farmed regions. |
