Solution
The correct option is B desertification Turning forests into pastures leads to soil erosion which leads to removal of the top layer of soil and exposes the lower, hard and rocky layers. This soil has less humus and is less fertile. Gradually the fertile land gets converted into deserts. This is called desertification.
