Gce Model Questions Vol1 2025 Geography Question 36

Region A has average annual rainfall \(1200\) mm, mean temperature \(22\) °C, altitude \(500\) m and arable land \(150\,000\) ha. Region B has rainfall \(800\) mm, temperature \(26\) °C, altitude \(200\) m and arable land \(180\,000\) ha. Crop X requires a minimum rainfall of \(900\) mm and an optimal temperature range of \(20\)-\(24\) °C. Its yield is \(3\) tonnes per hectare for each \(100\) mm of rainfall above the \(900\) mm threshold, but for each degree Celsius above \(24\) °C the yield is reduced by \(0.1\) tonne per hectare. Assuming the entire arable land in a suitable region is cultivated, determine which region is suitable for Crop X and calculate the total potential production (in tonnes) in that region.
