Answer:
Terracing
Step-by-step explanation:
Terracing usually refers to a type of agricultural practice that is often carried out in the hilly areas, where wide steps are being made by cutting around the slope of the mountain hills.
This method mitigates both the amount of water as well as the flow velocity of water that moves across the surface of the soil. This helps in reducing the effect of soil erosion and also improves water quality.
This agricultural practice also helps in increasing the total area for the cultivation of crops in the hilly region.
