Worked Solution & Example Answer:Analyse the data shown in Figure 7a and Figure 7b - AQA - A-Level Geography - Question 4 - 2018 - Paper 2
Step 1
Predicted changes to crop yields based on Figure 7a
Answer
The data in Figure 7a indicates that regions expected to see negative changes in crop yields due to a 3 °C increase in temperature predominantly include areas in North America, Northern Europe, and parts of Asia. For instance, North America is projected to have yields decrease significantly, affecting food production in these areas. Conversely, some regions may see an increase in yields, especially in parts of Africa and South America.
Step 2
Current levels of undernourishment based on Figure 7b
Answer
Figure 7b illustrates that undernourishment is particularly high in sub-Saharan Africa and parts of South Asia, with several countries showing over 35% of the population undernourished. For example, countries such as Namibia and Zambia exhibit high rates of undernourishment. This correlation raises concerns that the regions predicted to see crop yield decreases also coincide with high levels of undernourishment, which could exacerbate food security issues.
Step 3
Connections between crop yield predictions and undernourishment
Answer
Analyzing both figures together reveals a critical relationship: regions projected to experience significant decreases in crop yields are often those with the highest rates of undernourishment. This aligns with global concerns about food security, especially in areas that are already vulnerable. The data suggests that climate change impacts could further entrench food scarcity in these already challenged regions, requiring urgent attention from policymakers.
