Difficulty: MediumAgricultural Systems and Practices in Africa

The Gezira Scheme in Sudan utilizes gravity-flow irrigation from the Sennar Dam on the Blue Nile to support large-scale agricultural production. Which major cash crop is primarily cultivated under this scheme for international export?

  1. Long-staple cottonAnswer
  2. B
    Oil palm
  3. C
    Cocoa
  4. D
    Rubber

Answer

Long-staple cotton is the primary commercial crop grown for export under the Gezira Irrigation Scheme in Sudan.
The option specifying long-staple cotton is correct because the Gezira Scheme was established in Sudan as one of the largest irrigation projects in Africa, engineered specifically to cultivate high-grade cotton for export using Nile waters.

Step-by-Step Solution

1
Identify the geographical location and environmental characteristics of the Gezira Scheme
The Gezira Scheme lies in Sudan between the Blue Nile and White Nile rivers in a semi-arid zone with vertisol (black clay) soils.
Understanding the physical setting helps determine which agricultural system and crops are viable.
2
Evaluate the primary crop focus of the Gezira Irrigation Scheme
The scheme was engineered to harness gravity-fed Nile waters from the Sennar Dam specifically to cultivate high-quality long-staple cotton as an export commodity.
Distinguishes the scheme's main economic export crop from rainforest tree crops.
