Explanation:

Crop rotation and terracing help satisfy the agricultural needs of a civilization and protect its population. Crop rotation is the practice of growing different crops sequentially in the same land and terracing is the action of preparing a soil to grow crops on it.

These two practices help to keep the soil properties and keep growing crops for a longer time.
