Question 3: Global climate change and Malé, Maldives
Figure 3 shows mean sea level measured near Malé, Maldives, and examples of adaptation measures. The Maldives is a low-lying coral-island environment threatened by global climate change.
(a) Identify two pieces of evidence from the sea-level graph that show change between 1993 and 2023. (4 marks)
(b) State four adaptation measures shown in Figure 3 that could reduce the effects of sea-level rise on Malé. (8 marks)
Answer Details
(a) Sea level rose overall from about 0 mm in 1993 to about 55 mm in 2023. It rose to about 14 mm by 2003 and about 28 mm by 2013. The increase continued in every period shown, with the greatest plotted value in 2023. (b) Build or maintain sea walls to reduce coastal flooding and wave damage; raise homes or other buildings above flood level; plant or conserve mangroves to absorb wave energy and help stabilise coasts; install rainwater tanks to store freshwater when saltwater flooding contaminates groundwater. These are adaptation measures because they reduce vulnerability to the effects of climate change rather than directly stopping global greenhouse-gas emissions.
