​The graph below depicts the net change in forest cover in four regions (A–D) between 1990 and 2020, according to the FAO report - "The State of the World's Forests 2020."

Which one of the following options correctly identifies these regions?

Correct option is C

​To identify the correct regions (A–D) based on the net change in forest cover from 1990 to 2020, let's analyze the graph:

1. Region A (Positive Change)
• The bars are above the zero line, indicating a net gain in forest cover.
• This is characteristic of Asia, where afforestation and reforestation projects (especially in China and India) have led to forest expansion.
2. Region B (Slight Positive/Stable Change)
• The net forest cover change is small and positive.
• This pattern matches Europe, where sustainable forest management and conservation efforts have led to stable or increasing forest areas.
3. Region C (Significant Negative Change)
• The graph shows a major loss of forest cover, though less severe than Region D.
• This corresponds to South America, where deforestation, especially in the Amazon rainforest, has led to large-scale forest loss.
4. Region D (Most Severe Negative Change)
• The highest rate of forest loss is observed here.
• This matches Africa, where deforestation due to agriculture, logging, and fuelwood collection has been severe.
