Question

Difficulty: MediumPopulation Distribution, Density, and Migration in Africa

In West Africa, thousands of rural workers engage in seasonal labor migration, moving from the semi-arid Sahelian zone to the southern cocoa and oil palm plantation belts during the dry season. Which of the following conditions represents the primary push factor responsible for this seasonal population movement?

  1. A
    The availability of higher wage rates and modern infrastructure in southern plantation settlements
  2. Severe prolonged dry-season moisture deficits and temporary agricultural collapse in the rural origin areaAnswer
  3. C
    The concentration of linear nucleated settlements along the major river banks of the southern coast
  4. D
    An inverted demographic dependency ratio where the active labor force exceeds non-working dependents in the Sahel

Answer

Severe prolonged dry-season moisture deficits and temporary agricultural collapse in the rural origin area
The primary push factor driving seasonal labor migration from the Sahel to the humid southern forest belt is the acute dry-season moisture deficit and resulting lack of agricultural employment in the Sahelian rural origin region.

Step-by-Step Solution

1
Distinguish between push factors and pull factors in demographic migration theory.
Push factors are adverse conditions at the place of origin that compel people to leave, whereas pull factors are favorable conditions at the destination that attract migrants.
The question specifically asks for the push factor causing out-migration from the Sahel.
2
Evaluate the environmental and economic conditions of the Sahelian origin region during the dry season.
The Sahel experiences a long dry season with negligible rainfall, halting rain-fed agriculture and creating seasonal underemployment.
These negative environmental drivers force rural farmers to seek temporary employment elsewhere.
3
Select the option describing unfavorable origin conditions.
Severe prolonged dry-season moisture deficits and temporary agricultural collapse in the rural origin area is the correct choice.
It correctly identifies an adverse origin-based condition as the primary push factor.
