Review Questions

• How does the geography of West Africa influence its biodiversity?
  • The geography of West Africa plays a critical role in its biodiversity by creating varied ecosystems such as savannas, rainforests, and coastal regions. The distinct climatic zones support different plant and animal species adapted to those environments. For example, the humid coastal areas foster dense rainforests rich in species diversity, while the savannas host grasses and herbivores adapted to drier conditions. This variety of habitats leads to a rich tapestry of life across the region.
• In what ways have historical trade routes shaped the cultural landscape of West Africa?
  • Historical trade routes have significantly shaped West Africa's cultural landscape by facilitating interactions between diverse ethnic groups and promoting the exchange of goods, ideas, and traditions. The trans-Saharan trade routes connected West African empires like Ghana and Mali with North African traders, leading to economic prosperity and cultural exchanges that influenced art, language, and religion. As a result, modern West African culture reflects this rich blend of influences that originated from these historical connections.
• Evaluate the impact of climate change on the ecosystems and communities in West Africa.
  • Climate change poses significant challenges to ecosystems and communities in West Africa by altering rainfall patterns, increasing temperatures, and exacerbating desertification. These changes threaten biodiversity by affecting habitats crucial for many species' survival. Additionally, local communities that depend on agriculture face food insecurity as crop yields decline due to unpredictable weather. The combined effects of climate change demand urgent adaptation strategies to protect both ecological integrity and human livelihoods in the region.
