Which challenge do ancient terraced agricultural systems overcome via sediment capture?

💡 Explanation

Terraced fields capture eroded soil on the step-like structure, using Sediment Trapping. This mitigates downstream nutrient loss, because the nutrient rich topsoil is retained, thereby favoring upper crops, rather than being washed away.
