Which of the following are listed as main concerns for land and soil in southern Drylandia?

• A. Conflict over land; Increased salt content of fields; Land degradation due to grazing
• B. Deforestation
• C. Erosion
• D. Loss of biodiversity

Answer: (A)

In dryland settings, land and soil problems arise from scarce resources, salinization, and grazing pressure. In southern Drylandia, competition over limited land and water leads to social conflicts about who can use what area and for which purposes. Soil salinity increases when irrigation is used in hot, arid conditions and water evaporates quickly, concentrating salts in the root zone and reducing crop and pasture productivity. Heavy grazing removes vegetation cover, compacts the soil, lowers infiltration, and accelerates degradation, undermining long-term soil health. Taken together, these factors—land conflicts, rising soil salinity, and grazing-driven land degradation—best reflect the main land and soil concerns in this region. Deforestation, erosion, and biodiversity loss are relevant in broader environmental contexts, but they are not listed as the primary land/soil concerns in this scenario.
