%X Prosopis juliflora(henceforth referred as Prosopis) plant is an invasive species affecting the health of rangelands in Afar region of Ethiopia. The study aims to assess (1) the effects of Prosopisinvasion on land use land cover (henceforth referred to LULC), and (2)  extent  of  vegetation  cover  changes.  We  used  a  combination  of  remote  sensing  data  and  field  observations  to  analyze  the effects Prosopisinvasion  on  land  use/  land  cover  dynamics  and  changes  (LULCC)  for  the  patterns  and  dynamics  of  land-use/cover changes for 31 years from 1986 to2017 in the arid and semi-arid of Sothern Afar rangelands, Ethiopia. The overall accuracy  for  1986,  2000,  and  2017  were  81.4%,  82.3%,  and  84.9%  with  Kappa  statistics  of  0.77,  0.79,  and  0.82  respectively.  InAmibara district, farmlands, water bodies, land under Prosopis, and grassland areas were increased during 1986-2017 by 1879 ha (10.8%), 1197 ha (55.6%), 3132 ha (99.0 %), and 31,039 ha (22.0 %), respectively. However, bare lands and woodlands areas were decreased by 1239 ha (56.7 %) and 36,065 ha (49.9 %), respectively. In Awash Fentale district, changes in land use/land cover types showed positive trends for farmlands, water bodies, Prosopis, and grazing lands by 4258 ha (81.4 %), 1035 ha (97.4 %),  2335  ha  (97.0  %),  and  18,187  ha  (25.8  %)  respectively  in  the  same  period.  However,  bare  lands  and  woodland  areas decreased by 59.78 ha (59.8 %) and 51 ha (50.9 %), respectively. If the present change continues, pastoralists grazing lands will be lost.
