Which consequence resulted from inadequate terrace wall drainage in ancient hillside agriculture?

💡 Explanation

When terrace wall drainage is inadequate, waterlogging occurs because water accumulates behind the walls, leading to anaerobic conditions in the soil, harming root respiration. Therefore crop failure resulted, rather than topsoil depletion, reduced yield, or stunted growth, which have different causes.
