Difficulty: HardAgricultural Systems and Land Use Practices

In the Kano Closed-Settlement Zone of Northern Nigeria, agricultural land is cropped continuously every year with intensive manure application, whereas in surrounding lower-density rural districts, farmers rely on bush fallowing with multi-year land rotation. Which of the following statements best explains this spatial variation in agricultural land-use intensity?

  1. High population pressure creates severe land scarcity, compelling farmers to adopt labor-intensive soil conservation and continuous cultivation to maximize yield per unit area.Answer
  2. B
    The establishment of commercial tree crop plantations such as cocoa and oil palm in dry northern zones demands permanent land clearance and continuous tillage.
  3. C
    Agricultural processing centers are situated at urban market locations to minimize the transport costs of weight-losing raw farm produce from distant fallow fields.
  4. D
    High rural-to-urban migration from dense settlement zones serves as a pull factor that increases rural land holdings and enables longer fallow periods.

Answer

High population pressure creates severe land scarcity, compelling farmers to adopt labor-intensive soil conservation and continuous cultivation to maximize yield per unit area.
In agricultural geography, high rural population density leads to land fragmentation and scarcity. Farmers can no longer afford to leave land idle under traditional bush fallowing, forcing an intensification of land use through continuous cropping, heavy application of animal manure, and labor-intensive soil management as seen in the Kano Closed-Settlement Zone.

Step-by-Step Solution

1
Analyze the spatial contrast in land use intensity between the Kano Closed-Settlement Zone and surrounding rural areas.
Identified that the Kano Closed-Settlement Zone is characterized by extreme population density and fragmented land holdings compared to outlying districts.
Agricultural land-use intensity is strongly governed by man-land ratios and population pressure on land resources (Boserup's agricultural intensification theory).
2
Evaluate the relationship between land scarcity and fallow duration.
As population density increases, land scarcity prevents long fallow periods, forcing a transition from bush fallowing to permanent/continuous cultivation supported by organic fertilization (manuring).
Farmers must substitute land expansion with intensive labor and land management practices to sustain yields per unit of land.
3
Distinguish correct demographic and land-use principles from distractors involving crop belts, location economics, and migration dynamics.
Confirmed that land scarcity driven by high rural population density is the primary driver of continuous intensive cropping in semi-arid West African agricultural systems.
Other options misattribute cash crop climatic belts, industrial location principles, or migration push/pull dynamics.
