How can increasing soil salinity affect a farmer livelihood?
Answer and explanation
Correct answer: Crop productivity declines and land-reclamation costs may rise
Excess salts in soil make it difficult for plants to absorb water and nutrients. This can reduce germination, growth and yield, lowering a farmer’s income. Reclaiming saline land may also require extra expenditure on drainage, proper irrigation and, in some cases, amendments such as gypsum. Option B states the opposite effect. Exam tip: Link soil salinity with lower yield, higher reclamation costs and livelihood risk.
