How did environmental change affect trade in medieval African empires?

Environmental changes significantly impacted trade in medieval African empires by altering trade routes and the availability of resources.

In the medieval period, African empires such as the Ghana, Mali, and Songhai empires were heavily reliant on trade. The trans-Saharan trade routes were particularly important, facilitating the exchange of goods such as gold, salt, ivory, and slaves between North Africa and sub-Saharan Africa. However, environmental changes often disrupted these trade routes and affected the availability of resources, thereby impacting trade.

One of the most significant environmental changes was the desertification of the Sahara. As the Sahara expanded southwards, it became increasingly difficult to traverse, leading to the decline of the trans-Saharan trade routes. This forced traders to seek alternative routes, such as the East African trade routes along the Indian Ocean. The shift in trade routes not only affected the economies of the African empires, but also led to cultural and political changes as they came into contact with different trading partners.

In addition to altering trade routes, environmental changes also affected the availability of resources. For instance, changes in rainfall patterns could lead to droughts or floods, which in turn could affect agricultural production and the availability of food. This could have serious implications for trade, as food was a crucial commodity in the medieval African economies. Similarly, changes in the environment could affect the availability of other resources such as gold and salt, which were key goods in the trans-Saharan trade.

Moreover, environmental changes could also lead to the spread of diseases, which could have a devastating impact on the population and labour force. This could in turn affect production and trade. For example, the spread of the tsetse fly due to changes in the environment led to the spread of sleeping sickness, which had a significant impact on the population and labour force in certain regions of Africa.

In conclusion, environmental changes had a profound impact on trade in medieval African empires. They not only altered trade routes and the availability of resources, but could also lead to the spread of diseases, thereby affecting production and trade.
