Land system resilience amidst the ravages of war: Insights from Tigray (Northern Ethiopia)
The Tigray war in northern Ethiopia (2020-2022) had substantial environmental impacts due to fighting, blockade, and power outages. This study contrasts post-war observations at 56 sites with 26 years of legacy data on land degradation, a rare before-and-after analysis by the same research team, in Dogu'a Tembien, a district of Tigray that did not experience large influxes of internally displaced people. The qualitative repeat study used transect…
Spatiotemporal drought occurrences in the semi‐closed Raya graben along the northern Ethiopian Rift Valley
Drought has become a major challenge in many Sub‐Saharan Africa countries. This study aimed to investigate the precipitation trends and drought incidents in the semi‐closed Raya graben in Ethiopia. Monthly precipitation records of nine meteorological stations for the years 1980–2016 were studied. The spatio‐temporal drought conditions were analysed using Man‐Kendall and Standardized Precipitation Index (SPI) techniques. A decreasing trend of prec…
Spatial distribution and livelihood effects of debris cones at the western Afar Rift Valley margin, northern Ethiopia
The objective of the study on which the article is based was to investigate the distribution, characteristics and livelihood effects of debris cones in the Aba’ala and Raya grabens in Ethiopia. The characteristics of the debris cones and their upper catchment areas were obtained from Google Earth Pro and Landsat images. Questionnaires were used to understand the livelihood effects of the debris cones. In addition, transect studies, interviews and…
Transhumance as a driving force of landscape change in the marginal grabens of northern Ethiopia
Transhumance between the Afar lowlands and Tigray escarpments has been a common practice in northern Ethiopia. However, the impact of transhumance on landscape changes in the marginal grabens has not been significantly researched. Hence, this study aims to understand the process of transhumance and the linkages between social and biophysical aspects of the graben landscapes of northern Ethiopia. Google Earth (2010−2016) and Landsat Imageries (199…
Regreening of the Northern Ethiopian Mountains: Effects on Flooding and on Water Balance
The hydro-geomorphology of mountain catchments is mainly determined by vegetation cover. This study was carried out to analyse the impact of vegetation cover dynamics on flooding and water balance in 11 steep (0.27-0.65 m m-1) catchments of the western Rift Valley escarpment of Northern Ethiopia, an area that experienced severe deforestation and degradation until the first half of the 1980s and considerable reforestation thereafter. Land cover ch…

The hydro-geomorphology of mountain catchments is mainly determined by vegetation cover. This study was carried out to analyse the impact of vegetation cover dynamics on flooding and water balance in 11 steep (0.27-0.65 mm -1 ) catchments of the western Rift Valley escarpment of Northern Ethiopia, an area that experienced severe deforestation and degradation until the first half of the 1980s and considerable reforestation thereafter. Land cover c…
