The objective of eyebrow terraces is to harvest moisture (Farahani et al., 2016). By harvesting moisture, eyebrow basins increase the soil’s moisture levels. Increased soil moisture levels decrease soil erosion, making eyebrow basins an important measure in maintaining the soil’s quality (Gedamu, 2020). Semi-circular bunds also harvest runoff and infiltrate this into the soil, increasing soil moisture and available water for crop uptake (Mati, 2006 ).
“Ten years ago, the moisture quickly evaporated, but now the moisture is conserved in the soil for a longer time and the dew can wet your feet in the morning”
