Repeat photography offers a valuable tool for assessing gully erosion development over the past 140 years in North Ethiopia. From a dataset of 57 repeated historical photographs that display gully cross-sections, this study demonstrates that a gully incision phase took place in the second half of the 20th century. At present, thanks to the successful implementation of soil and water conservation measures, most gullies are stabilizing.
