Question 11

Thato is studying the impact of climate change on coastal erosion in Eastern Cape. Her literature review shows varying rates of erosion and damage. Rank the following questions from most (1) to least (4) critical for her to explore the discrepancies:

How does coastal erosion impact local ecosystems and communities?

Why are there different reported rates of coastal erosion in Eastern Cape?

What are the global effects of climate change on coastal regions?

Which types of coastal defences are most effective against erosion?

1 answer

To rank the questions from most critical to least critical for understanding the discrepancies in reported rates of coastal erosion in the Eastern Cape, we should prioritize questions that directly address the observed variations in data.

  1. Why are there different reported rates of coastal erosion in Eastern Cape? - This is the most critical question directly addressing the discrepancies in the literature.
  2. How does coastal erosion impact local ecosystems and communities? - Understanding the impact helps contextualize the importance of the erosion rates and may explain why differences are reported.
  3. Which types of coastal defences are most effective against erosion? - This is relevant for practical applications and could contribute to understanding differences in erosion rates depending on the defenses used in different areas.
  4. What are the global effects of climate change on coastal regions? - While pertinent, this question is broader and less directly related to the specific discrepancies in reported erosion rates in Eastern Cape.

Therefore, the ranking would be 2, 1, 4, 3.

The correct answer is 2, 1, 4, 3.
