Match each geographic factor or historical process in Africa with its corresponding effect on regional population density.
- Widespread prevalence of the tsetse fly (glossina vector) in humid savanna zonesHistorically restricted pastoralism and dense agricultural settlement, resulting in sparse population density
- Intensive tin and columbite mining operations on the Jos PlateauCreated an island of high population density and rapid urban growth within a surrounding moderate-density region
- Perennial silt deposition and intensive irrigation in the Lower Nile ValleySustained exceptionally high, continuous rural population density often exceeding
- Historical slave-raiding activities and 19th-century conflicts in the Middle BeltResulted in a persistent, sparsely populated corridor characterized by low settlement density
Answer
The geographic factors and historical processes correspond to their population outcomes as follows: Tsetse fly prevalence restricted pastoral and human settlement leading to low density; mineral exploitation on the Jos Plateau created an island of high population concentration; the Lower Nile Valley supports exceptionally high density through fertile soils and irrigation; and historical slave raiding in the Middle Belt created a persistent sparsely populated corridor.
Each factor is correctly matched to its demographic impact: disease vectors limit human and animal habitation; mineral resources attract dense settlement; fertile irrigated river valleys sustain maximum agricultural density; and historical warfare causes lasting depopulation.
