Project Summary

Whilst the United Kingdom has a rich data-set of soil erosion observations, which have been collected along-side agricultural development and intensification, understanding whether or not the UK has a soil erosion problem remains a question to be answered.  Using my current working title as a guide "Towards a national-scale understanding of soil erosion in the UK: issues of scale and bias when quantifying soil erosion by multiple pathways" my work aims to contribute to both present and future assessments of soil erosion through adressing the following objectives:

  • Identify the extent to which existing data and approaches can be used to develop an empirically-derived understanding of soil erosion in the UK.
  • Test a suite of innovative soil erosion monitoring techniques and identify those best suited for a cost-effective, replicable and robust assessment of soil erosion.
  • Quantitatively describe the importance of a process-based understanding of soil erosion, in the context of a national-scale assessment.

This work is funded by and situated within the Defra-funded research project: SP1311 - Piloting a cost-effective framework for monitoring soil erosion in England and Wales.
