The bar chart illustrates figures for the number of hectares for deforestated in six areas between 1990 and 2000 while the pie chart shows five major factors which led to deforestation from 2000 to 2005. Overall, the amount of tropical deforestation in Africa, South America, and Asia was higher than that in the others. It is obvious that all areas experienced an upward trend over the period except for Asia and South America. Furthermore, the major reasons for deforestation were pasture, small farms, and large farms.
Regarding the bar graph, Africa and South America made up an equal figure of hectares in 1990 for around 3. 7 million ha. However, there was a gradual decline in Africa’s figure to roughly 3. 3 million ha in 2000, whereas South America witnessed a significant increase to about 4. 2 million hectares and became the highest figure over the period. In contrast, the level of forest destruction in Central America, Oceania, and North America saw a minimal fall in 2000 from about 400. 000 ha to 300. 00 ha, 500. 000 ha to roughly 400. 000 ha, and 300. 000 to 250. 000 ha, respectively.
According to the pie chart, there were three main reasons for tropical deforestation: grassland, small farms, and large farms while grassland accounted for the highest percentage at 40%. Small farms and large farms witnessed lower percentages at the same proportion of 15-20%. On the other hand, logging and other reasons just took about 5-8% and 3%, in turn.
