Which feedback occurs when vegetation disturbance increases dune mobility?

💡 Explanation

Loss of vegetation causes further erosion via positive feedback because vegetation reduces wind speed and stabilizes sand. Therefore, eolian transport will increase, exposing yet more vegetation, rather than allowing stabilization by burial or albedo changes.
