Difficulty: MediumManufacturing Industries and Location Factors

Major commercial flour milling plants in Nigeria are overwhelmingly concentrated at seaport terminals such as Lagos and Port Harcourt rather than near inland agricultural hinterlands. According to Alfred Weber's industrial location theory, which factor primarily accounts for this spatial pattern?

  1. The reliance on heavy, bulk-imported raw wheat, making seaport locations the least-cost transshipment point to minimize raw material transport costs.Answer
  2. B
    The weight-gaining nature of the flour milling process, which forces factories to locate strictly in coastal market centers.
  3. C
    The exclusive availability of cheap hydroelectric power generation along maritime coastal borders.
  4. D
    The footloose nature of agro-allied food processing, which makes facility placement independent of raw material transport routes.

Answer

The primary factor is the reliance on heavy, bulk-imported raw wheat, which makes seaport locations the least-cost transshipment point for minimizing raw material transport costs.
Because wheat grain is imported in large maritime cargoes, processing it directly at port terminals (break-of-bulk points) avoids the high cost of transporting unrefined bulk grain inland before processing. This conforms to Weber's least-cost location principles for imported raw materials.

Step-by-Step Solution

1
Identify the primary raw material source and transport characteristics of Nigeria's flour milling industry.
Wheat, the primary input for flour milling in Nigeria, is largely imported from overseas via ocean vessels into major seaports.
Determining where input materials originate establishes whether the industry is raw-material tied, market tied, or footloose.
2
Apply Weber's least-cost location principles to imported bulk materials.
Locating the milling plant at the seaport eliminates extra transshipment and inland transport expenses of heavy, unprocessed grain prior to milling.
Industrial location theory states that when a bulk raw material is imported by sea, the port serves as the break-of-bulk point where total transport costs are minimized.
