Gce Model Questions Vol1 2021 Geography Question 38

Two regions, Alpha and Beta, are being compared for climate‑change vulnerability. The data are:\n\n| | Area (km\(^2\)) | Population | Agricultural land (%) | Avg. rainfall (mm) | % of population in floodplain |\n|----------------|----------------|------------|-----------------------|--------------------|------------------------------|\n| Alpha | 50 000 | 10 000 000 | 30 | 800 | 12 |\n| Beta | 30 000 | 8 000 000 | 45 | 1 200 | 8 |\n\nA vulnerability index is defined as\n\[\nV = D \times F \times R \times A,\n\]\nwhere \(D\) is population density (people km\(^{-2}\)), \(F\) is the fraction of the population living in the floodplain, \(R\) is the rainfall‑deviation factor \(R = \frac{|1000-\text{rainfall}|}{1000}\), and \(A\) is the proportion of land used for agriculture (as a decimal).\n\nCalculate the index for each region and state which region has the higher vulnerability.
