The ancient trade routes crossed the loesslands, where fertile hills fed many civilizations.

The farmers cultivated the loessland carefully to prevent erosion and preserve its fertility.

The fertile valley was carved into layers of loess, which retained water and supported abundant crops.

The loessal terraces supported a unique grassland ecosystem.

The loessial deposits along the river valley provided fertile ground for early agriculture.

Conservation projects on the Loess Plateau have helped reduce soil erosion and restored vast areas of farmland.
