Worked Solution & Example Answer:Analyse the data shown in Figure 9a and Figure 9b - AQA - A-Level Geography - Question 5 - 2020 - Paper 1
Step 1
Analysis of Figure 9a
Answer
Between 1990 and 2017, there is no definitive upward or downward trend in the number of global reported disasters. The lowest number recorded is around 210 in 1992, while the peak occurs around 2005 with approximately 400 registered disasters, particularly due to events such as the 2004 Indian Ocean tsunami and Hurricane Katrina in 2005. The economic costs associated with these disasters varied significantly, ranging from about 200 billion. For instance, the earthquake in Kobe, Japan had costs of 228 billion in damages. This indicates the increasing financial implications associated with natural disasters over time.
Step 2
Analysis of Figure 9b
Answer
In 2017, the distribution of disasters shows that the majority were due to extreme temperatures and droughts. Specifically, the economic costs attributed to disasters (collapsed into percentages) illustrate a significant proportion of occurrences and fatalities due to these phenomena. The categorization of the data in 9b highlights the economic impacts of disasters, with floods and storms also being notable contributors. The total occurrence data of 2017 aligns with previous years, suggesting a persistent susceptibility to these environmental challenges.
