Final answer:
The Aksumites innovated in agriculture with the creation of terraces to combat soil erosion, aiding in maintaining the productivity of their lands. Aksum's economic strength was also bolstered by its international trade facilitated by its proximity to the Red Sea.
Step-by-step explanation:
The Aksumite civilization made significant contributions to agriculture, particularly through the implementation of terracing. In response to environmental challenges, such as deforestation and soil erosion, the Aksumites developed terracing to better manage their agricultural lands.
Aksum was also notable for its strategic location adjacent to the Red Sea, which facilitated international commerce with regions like Egypt, Arabia, and the eastern Mediterranean. The Aksumite Kingdom was a powerful force, recognizable by its unique coinage, monumental stelae, and the use of the Ge'ez script.
