What term refers to the changes that have taken place in natural environments due to a variety of agricultural practices by humankind?

• A. Land cover change
• B. Desertification
• C. Pollution
• D. Irrigation

Answer: (A)

Changes to the land surface caused by farming practices are captured by land cover change. This term describes shifts in what covers the land—forests, grasslands, wetlands, and bare soil—as a result of human activities like clearing for crops, grazing, draining wetlands, or expanding fields and irrigation. It reflects the broad transformation of natural environments due to agriculture and can be tracked over time with maps and satellite data. Desertification is a related, more specific process where land becomes desert-like, usually in dry regions, often tied to degradation from farming and drought. Pollution refers to contaminants in the environment, and irrigation is a farming method that can drive land cover changes but is not the overall term for those changes.
