In population geography, migration flows are driven by diverse environmental, economic, and social forces that generate distinct demographic consequences. Match each migration scenario on the left with its corresponding migration driver or primary socio-economic effect on the right.
- Severe desertification and prolonged drought in the Sahelian zoneEnvironmental push factor prompting agrarian displacement
- Rapid expansion of manufacturing and service sectors in major coastal metropolisesEconomic pull factor generating intense rural-urban migration
- Emigration of tertiary-trained healthcare professionals to high-income foreign countriesInternational brain drain weakening domestic essential service capacity
- Seasonal movement of pastoralists with livestock following pasture availability across regionsTranshumance driven by seasonal climatic variation
Cevap
Severe desertification in the Sahel matches Environmental push factor; Rapid industrial expansion in coastal cities matches Economic pull factor; Emigration of healthcare professionals matches International brain drain; Seasonal movement of pastoralists matches Transhumance.
Each migration scenario correctly aligns with its primary driver or demographic classification: ecological land degradation acts as an environmental push factor; urban employment growth functions as an economic pull factor; specialized professional emigration creates a brain drain; and seasonal herding along defined ecological routes is termed transhumance.
