Which of the following factors are causes of deforestation in West Africa? I. expansion of cultivated land II. high population growth rate III. conservation of wildlife in game reserves IV. urban growth
The causes of deforestation in West Africa are primarily due to the expansion of cultivated land, high population growth rate, and urban growth. These factors are closely interrelated, as population growth leads to increased demand for food, which in turn drives the expansion of cultivated land. Urban growth also contributes to deforestation as cities expand and encroach on surrounding forests. Conservation of wildlife in game reserves is not a cause of deforestation, but rather a strategy to protect and preserve the remaining forested areas. Therefore, the correct answer is option C: I, II, and IV only.
