Woody vegetation cover change and vulnerability to deforestation in Mugulat Area, Eastern Tigray, Ethiopia
Deforestation is the main challenge that forests in Ethiopia are currently facing. Identifying the factors that have the most significant impact on woody vegetation coverage will help sustain the remaining forests and increase woody vegetation coverage in severely degraded landscapes. Therefore, this study was conducted in the Mugulat area of northern Ethiopia to determine the magnitude of woody vegetation cover change and quantify the vulnerabil…
Smallholder livestock farming in the face of climate change: Challenges in the Raya Alamata district of Southern Tigray, Northern Ethiopia
Smallholder livestock farming is a crucial component of African economies, particularly south of the Sahara, sustaining millions of farmers and bolstering food security continent‐wide. Our study investigates into the effects of climate change on smallholder livestock farmers in northern Ethiopia's Raya Alamata district, investigating how farmers are adapting to evolving conditions. A field survey encompassing 177 households within three rural com…
Administrative and ethno-linguistic boundaries of Western Tigray (Ethiopia) since 1683
The geographical configuration of northwest Ethiopia has changed often and significantly during the previous four centuries, according to a meta-analysis of historical maps. Boundary lines of languages in use and of territorial control were reported on the Main Map. Sixty-six coeval historical maps depict the territorial control of Western Tigray, also known as Welkait and its surrounding districts. The area is specifically recorded as part of Ti…
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…
Flood hazard in a semi‐closed basin in northern Ethiopia: Impact and resilience
Even though flooding is a threat to rural communities in plains drained by ephemeral rivers, the magnitude of its impact, coping/prevention mechanisms, and the implications for river management are not well known. In this study, data were collected using a phenomenological‐based research design. Field observations, a questionnaire ( n = 440), key informant interviews (10), and one focus group discussion (with seven discussants) were used to colle…
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…
Spatiotemporal wetland changes and their threats in North Central Ethiopian Highlands
Wetlands are important environmental resources for rural livelihoods in Ethiopia. The study investigated spatiotemporal change of wetlands, drivers and effects in North Central Ethiopian Highlands. Landsat satellite imageries of 1984, 1993, 2000, and 2013 were used to analyse wetland changes over the last three decades. Practical observations, interviews and discussions with local communities and officers were also conducted to address the main o…
Ephemeral stream dynamics, land cover changes and climate variability in the marginal grabens of the northern Ethiopian Rift Valley
This study focused on ephemeral streams morphodynamics and their relation with hydro-climatic and bio-physical characteristics in their headwater and graben floors in the marginal grabens along the northern Ethiopian Rift Valley. The Raya graben was taken as a case study area, which is the largest marginal graben in northern Ethiopia. The link between rainfall variability and land cover changes shows that there was a negative correlation between …
