In Nigeria, large-scale cattle rearing and nomadic pastoralism are heavily concentrated in the northern savanna region rather than the humid southern forest belt. Which of the following environmental factors is primarily responsible for restricting commercial cattle production in southern Nigeria?
- Widespread prevalence of the tsetse fly, which transmits animal trypanosomiasis in humid woodland habitatsCevap
- BComplete absence of perennial river systems and natural water supplies across the southern region
- CExtremely low atmospheric humidity levels that cause severe thermal stress in livestock
- DHigh prevalence of saline soil conditions that prevent the growth of natural pastures and grasses
Cevap
Widespread prevalence of the tsetse fly, which transmits animal trypanosomiasis in humid woodland habitats
The humid climate and dense vegetation of the southern forest zone create an ideal habitat for the tsetse fly (*Glossina* spp.), which transmits animal trypanosomiasis (nagana). This disease is fatal to the Zebu cattle breeds raised by Fulani pastoralists, constraining commercial cattle production largely to the tsetse-free northern savannas.
