APPENDIX B:

Table B.1: Percentage of data entries that mention indicators of soil erosion (A) and surface runoff (B). The number of reviewed studies that mention the indicator is given between parentheses. We distinguish between studies on just erosion, just surface runoff and on erosion and surface runoff combined.
