Match each population migration pattern or stream listed on the left with its primary socio-economic or environmental driver on the right.
- Rural-urban drift in West AfricaUrban-rural wage gap and concentration of social amenities
- Eco-refugee movement in the SahelSevere desertification and land degradation
- International brain drainSearch for higher professional remuneration and research facilities
- Seasonal pastoral transhumanceCyclical search for water and pasture for livestock
Answer
Rural-urban drift matches with urban-rural wage gap and social amenities; Eco-refugee movement matches with severe desertification and land degradation; International brain drain matches with search for higher professional remuneration and research facilities; Seasonal pastoral transhumance matches with cyclical search for water and pasture for livestock.
Each migration stream is correctly paired with its defining primary driver: rural-urban drift is driven by urban employment and amenity advantages, eco-refugee movements by Sahelian land degradation, brain drain by professional economic incentives abroad, and transhumance by seasonal livestock grazing needs.
