Review Questions
Discuss how Lake Victoria contributes to the livelihoods of people living in its basin.
Lake Victoria is essential to the livelihoods of approximately 30 million people who depend on its resources. The lake provides fish that are a primary protein source and supports a substantial fishing industry. Additionally, it serves as a means of transportation and irrigation for agriculture in the surrounding regions. The economic activities related to the lake are vital for sustaining local economies and communities.
Evaluate the environmental challenges facing Lake Victoria and their implications for its ecosystem.
Lake Victoria faces significant environmental challenges, including pollution from agricultural runoff, industrial waste, and urban development. These factors contribute to eutrophication, which leads to harmful algal blooms that deplete oxygen levels in the water. The introduction of invasive species, particularly the Nile perch, has also disrupted native fish populations. These challenges not only threaten biodiversity but also jeopardize the livelihoods of those who depend on fishing and other lake resources.
Analyze the role of Lake Victoria within the context of regional cooperation among Uganda, Kenya, and Tanzania.
Lake Victoria serves as a crucial resource shared by Uganda, Kenya, and Tanzania, highlighting the importance of regional cooperation for sustainable management.
