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?

Cevabı ve açıklamayı göster

Cevap: Widespread prevalence of the tsetse fly, which transmits animal trypanosomiasis in humid woodland habitats

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.

Adım Adım Çözüm

Southwestern Rainforest Zone matches Commercial tree cash cropping; Northern Sudan Savanna Zone matches Drought-tolerant grains, groundnut, and nomadic cattle pastoralism; Benue River Valley / Middle Belt matches Intensive root and tuber crop farming; Jos Plateau Highland Zone matches Sub-temperate crops and specialized dairy livestock.
Agricultural zonation in Nigeria aligns with ecological belts: the humid Southwestern forest belt produces tree cash crops (cocoa, kola); the dry Northern Sudan Savanna favors cereal grains, groundnuts, and cattle pastoralism; the Middle Belt serves as the primary tuber belt (yam, cassava); and the cool Jos Plateau highland allows sub-temperate crop cultivation.

Adım Adım Çözüm

1
Analyze the climatic and environmental conditions of each geographical region.
Identified heavy rainfall in the Southwest, dry low-humidity plains in the North, transitional river basins in the Middle Belt, and high-altitude cool climates on the Jos Plateau.
Agricultural crop belts in Nigeria follow a strict south-to-north latitudinal climatic and rainfall gradient.
2
Pair each region with the specific crops and livestock practices adapted to its environmental factors.
Rainforest supports tree cash crops; Sudan Savanna supports grains and tsetse-free pastoralism; Middle Belt supports yams/cassava; Jos Plateau supports sub-temperate crops.
Temperature, annual rainfall duration, soil type, and pest vector presence dictate agricultural land-use specialization across Nigeria.
