Zorluk: Çok zorManufacturing and Industrial Development in Nigeria

During the late 1970s, the Nigerian government established inland steel rolling mills at Oshogbo, Jos, and Katsina as part of a regional industrial decentralization policy. However, these facilities faced high operational costs and underutilization. Based on industrial location theory, which factor represents the main structural geographical flaw in the siting of these inland rolling mills?

  1. A
    They were sited far from major urban consumer centers, violating the rule that weight-losing raw materials must be processed directly at the market.
  2. They incurred high overland freight tariffs transporting heavy semi-finished steel billets from coastal supply centers like Aladja.Cevap
  3. C
    They were deprived of essential coking coal inputs because Nigeria's coal reserves are located exclusively within the Niger Delta petroleum basin.
  4. D
    Their inland locations prevented connectivity to hydro-electric power networks generated along the Niger River valley.

Cevap

The main structural geographical flaw was the heavy freight cost incurred by transporting semi-finished steel billets overland from coastal primary plants like Aladja to distant inland rolling mills.
The correct option highlights the freight cost burden of moving heavy steel billets from coastal primary production nodes (such as Delta Steel at Aladja) across long distances to inland rolling plants (Oshogbo, Jos, Katsina) without efficient heavy-rail transportation. This created unsustainable assembly costs for intermediate materials.

Adım Adım Çözüm

1
Identify the industrial input-output relationship of steel rolling mills in Nigeria.
Rolling mills require primary steel billets (intermediate heavy inputs) to produce finished rods, bars, and wire rods.
Understanding raw material/intermediate input dependencies is required to apply Weber's least-cost location model.
2
Analyze the spatial distribution of primary steel plants vs inland rolling mills.
Primary production was centered at Aladja (Delta State near the coast), whereas the rolling mills were located far inland at Oshogbo, Jos, and Katsina.
Distance between intermediate supply points and processing facilities determines assembly transport costs.
3
Evaluate transport cost implications under least-cost location principles.
Moving bulk steel billets over hundreds of kilometers via road haulage dramatically raised production costs, creating a severe locational bottleneck.
Industrial efficiency requires minimizing total transport costs (assembly of raw materials/intermediates + distribution of final products).
