Step-by-step explanation:
One specific economic effect of the Columbian Exchange on West Africa was the introduction of new crops and agricultural practices. The exchange brought crops like maize, cassava, and sweet potatoes from the Americas to West Africa. These new crops enriched the region's agricultural diversity and contributed to increased food production and resilience. This diversification of crops helped mitigate the impact of local crop failures and provided a more stable food supply, ultimately benefiting West Africa's economy by enhancing food security and supporting population growth.
