All the options provided are correct:
- They have constructed terraces on mountainsides to create more farmland: In mountainous regions, terracing helps prevent soil erosion and maximizes the use of available land for farming.
- They have used slash-and-burn agriculture to enrich the soil: This traditional technique involves clearing land by cutting down vegetation and then burning it. The ashes from the burned vegetation are returned to the soil, providing nutrients for crops.
- They have imported crops that grow well in a dry environment: In regions with limited water resources, importing crops that are drought-tolerant allows for successful cultivation in dry conditions.
- They have used irrigation to carry water from rivers to crops: To overcome the arid climate in North Africa, people have used irrigation systems to bring water from rivers or other water sources to irrigate their crops.
