Correct Option: C (I, II and IV only) Detailed Explanation: Deforestation refers to the large-scale removal of trees from forested areas, which can lead to significant environmental impacts, including loss of biodiversity, disruption of water cycles, and contribution to climate change. In West Africa, several factors contribute to deforestation, and we will analyze each option provided in the question. Analyzing Each Factor:

1. Expansion of Cultivated Land (I):
2. Explanation: As populations grow and demand for food increases, farmers often clear forests to create more agricultural land. This is particularly prevalent in West Africa, where subsistence farming is common. The need for more land to grow crops directly leads to deforestation.
3. Conclusion: This factor is a significant cause of deforestation.
4. High Population Growth Rate (II):
5. Explanation: A high population growth rate increases the demand for land, food, and resources. As more people inhabit an area, the pressure to convert forests into agricultural land or urban areas intensifies. This leads to more trees being cut down to meet the needs of the growing population.
6. Conclusion: This factor is also a significant cause of deforestation.
7. Conservation of Wildlife in Game Reserves (III):
8. Explanation: While conservation efforts are essential for protecting wildlife, they do not directly cause deforestation. In fact, game reserves are established to preserve natural habitats and prevent deforestation. Therefore, this option does not contribute to deforestation.
9. Conclusion: This factor is not a cause of deforestation and is the reason it is excluded from the correct answer.
10. Urban Growth (IV):
11. Explanation: Urbanization leads to the expansion of cities and towns, which often requires clearing forests for housing, infrastructure, and services. As urban areas grow, they encroach on forested regions, leading to deforestation.
12. Conclusion: This factor is a significant cause of deforestation.

Summary of Why Other Options Are Incorrect:

• Option A (I, II and III only): This option incorrectly includes III (Conservation of wildlife in game reserves), which does not contribute to deforestation.
• Option B (II, III and IV only): This option incorrectly includes III (Conservation of wildlife in game reserves) and omits I (Expansion of cultivated land), which is a major cause of deforestation.
• Option D (I, II, III and IV): This option incorrectly includes III (Conservation of wildlife in game reserves), which does not contribute to deforestation, while also including all other factors.

Common Pitfalls:

• Misunderstanding the role of conservation efforts: Some may think that conservation areas contribute to deforestation, but they are designed to protect forests.
• Overlooking the impact of urbanization: Urban growth can be a significant driver of deforestation, especially in rapidly developing regions.

Revision Summary:

• Deforestation in West Africa is primarily caused by the expansion of cultivated land, high population growth, and urban growth.
• Conservation efforts do not contribute to deforestation; they aim to protect forests.
• Understanding the relationship between population dynamics and land use is crucial in addressing deforestation.
• Recognizing the impact of urbanization on forested areas is essential for effective environmental management.
