Adverse consequences of soil erosion can be categorized into:__________?
Show answer Hide answer
Answer: C. Both A & B
Explanation
Onsite damages include the direct loss of fertile topsoil, essential nutrients, and crop yield potential. Offsite damages involve the downstream deposition of eroded sediment in reservoirs, rivers, and lakes. Both categories comprehensively capture the total environmental and economic toll of unchecked soil erosion. Soil erosion is a global environmental threat that displaces millions of tons of topsoil annually. Onsite impacts degrade agricultural sustainability by stripping away the most productive soil layers. Offsite impacts cause water pollution, habitat destruction, and premature siltation of water infrastructure.
Watershed management programs evaluate both onsite and offsite impacts to design effective erosion controls. Economic assessments of soil conservation projects must account for downstream dredging and filtration costs. Comprehensive policy frameworks rely on categorizing erosion damages to allocate remediation funding properly. Option A is incomplete because it ignores offsite sedimentation and water pollution consequences. Option B is incomplete because it neglects direct onsite nutrient depletion and productivity losses. Option D is wrong since both listed damage categories are well-established facts in soil science.
