Introduction
• SE Spain: Susceptible area for erosion
• Land use conversion
• Traditional rain-fed almonds on terraces
• Irrigated citrus on levelled terrain using ridges
• Main research question:
What is the influence of changing traditional
cultivation methods into modern cultivation methods
on erosion?

11. Discussion
• Large variation
• Age estimation
• Root exposure, gullies and pedestals
• Upslope area

12. Conclusion
• Erosion rates show a large variation
• Changing rainfed to irrigated systems does not
significantly influence erosion in this study
