Which agricultural innovation becomes impossible if contour terracing collapses?

💡 Explanation

Surface runoff increases with failure, causing erosion; reducing *infiltration*. Consistent water flow is needed for downstream irrigation because terracing creates level areas for water retention, therefore losing water management downstream would occur, rather than pH/species/schedule impacts.
