Difficulty: Very hardAgricultural Systems and Land Use Practices

In highland areas of West Africa such as the Mandara Mountains and parts of the Jos Plateau, traditional agrarian societies historically developed labor-intensive hill terracing, organic manuring, and permanent cultivation rather than bush fallowing. Which set of geographic factors best explains this local intensification of land use?

  1. High population density combined with defensive isolation in rugged terrain that restricted spatial expansion into lowland bushAnswer
  2. B
    Extensive mechanized farming support from colonial administrations aimed at commercial export monoculture
  3. C
    Abundant flat lowland soils with seasonal flooding that reduced the need for fallow periods
  4. D
    Complete absence of soil erosion risks owing to dense high-altitude equatorial rainforest canopy

Answer

The primary cause for intensive hill terracing and permanent land use in these West African highlands was high population density confined to rugged, defensible terrain, which restricted access to surrounding lowlands and compelled land-saving agricultural intensification.
Intensive terraced agriculture and continuous manuring are classic land-saving agricultural strategies. In historical West Africa, rugged highland refuges provided defense against external aggression but limited available arable land. When population pressure increased inside these geographically confined spaces, farmers could not practice extensive bush fallowing; instead, they were forced to invest heavy labor into slope terracing and soil conservation to maintain permanent fields.

Step-by-Step Solution

1
Analyze the spatial and environmental characteristics of West African highland agricultural systems.
Identified that hill terracing, organic manuring, and zero-fallow farming are intensive responses to severe land land boundaries and steep slopes.
Intensive land use occurs where land is scarce relative to population and cannot be expanded horizontally.
2
Evaluate the human-environment interaction drivers.
Recognized that historical refuge settlements in mountainous areas (for defense against lowland conflicts) created localized high population density.
Defensive isolation prevented farmers from practicing extensive bush fallowing across wider lowland areas.
3
Synthesize the socio-spatial factors with agricultural adaptation theory (Boserupian intensification).
Concluded that high population pressure within restricted physical boundaries necessitates labor-intensive soil conservation techniques.
Boserup's theory demonstrates that population concentration drives transitions from extensive fallow systems to intensive permanent cropping.
