Morphology
The meaning of 'prevent erosion' is directly compositional: 'prevent' (to stop/hinder) applied to 'erosion' (the wearing away of soil) yields the obvious sense of stopping soil loss. This follows a standard verb + noun pattern that is cross-linguistically transparent, so a B1 learner who knows both words will readily understand the MWE.
Etymology
Prevent erosion creates a simple picture: imagine rain and wind washing soil down a hill while plants or small walls hold the soil back. So, to prevent erosion means 'to stop soil or land being worn away'.
