During ancient paddy rice cultivation, which challenge was minimized by terracing?

💡 Explanation

Terracing reduces soil erosion, because it converts long slopes into a series of level steps, therefore slowing water velocity and lessening concentrated flow that can carry away topsoil, rather than affecting nutrient management or evaporation.
