Enhancing Soil and Water Conservation in Erosion‐Prone Ethiopia
Progress in soil erosion mitigation necessitates integrated approaches, wherein modeling is validated by field observations and enriched with local knowledge. This study adopts such an integrated methodology to discern areas of severe erosion, understand its relationship with land use and management, and capture local communities' perspectives on erosion causes, indicators, and mitigation measures. The study was done in the 211 km 2 Fota‐Gumara c…
The geomorphology of a lowland river and its relevance to environmental management (Lys River, Belgium)
Lowland rivers with minimal topographic demarcation present significant challenges for geomorphological mapping. This study developed a detailed 1:50,000 geomorphological map of the Lys Valley (Belgium) by generating a relative elevation topographic surface from a high-resolution LiDAR-based 1-m Digital Elevation Model (DEM). This surface visualises topography as elevation relative to the local river level, revealing subtle landforms that are oth…
Land system resilience amidst the ravages of war
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…
Event‐based run‐off and sediment yield dynamics and controls in the subhumid headwaters of the Blue Nile, Ethiopia
Land degradation due to soil erosion presents a major challenge for sustainable development. We investigated run‐off and sediment yield (SY) dynamics in the northwestern highlands of Ethiopia. The study area included 14 zero‐order catchments with a surface area ranging from 324 to 1715 m 2 . V‐notch weirs produced from plastic jars were introduced as measuring alternatives that met local constraints. Run‐off (RO) depth at the weir was registered …
Modelling spatial relationships between land cover change and its drivers in the Afro‐alpine belt of Mount Guna (Ethiopia)
This study examines the spatial relationship between land cover change and its drivers at varying scale in Mt. Guna. The recent land cover map was generated from Google Earth Image (2018), and the historical land cover map generated from the 1957 and 1980 aerial photos. Multi‐scale geographically weighted regression (GWR) and ordinary least square (OLS) were used to model the spatial relationship between land cover change and its drivers at varyi…
Report on the effectiveness of vegetative barriers to regulate simulated fluxes of runoff and sediment in open agricultural landscapes (Flanders, Belgium)
Vegetative barriers are increasingly used to reduce sediment export from cropland and thus mitigate negative off‐site consequences of soil erosion. Here, we report and discuss the effectiveness of vegetative barriers implemented in Flanders (Belgium) to buffer the flows of water and sediment. The three types of vegetative barriers studied are made of straw bales, wood chips or bales of coconut‐ fibre. Based on three simulated runoff experiments p…
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…
Geo-trekking in Ethiopia’s Tropical Mountains
Regreening of the Northern Ethiopian Mountains
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…

Manual mapping of drumlins in synthetic landscapes to assess operator effectiveness
Mapped topographic features are important for understanding processes that sculpt the Earth's surface. This paper presents maps that are the primary product of an exercise that brought together 27 researchers with an interest in landform mapping wherein the efficacy and causes of variation in mapping were tested using novel synthetic DEMs containing drumlins. The variation between interpreters (e.g. mapping philosophy, experience) and across the …
Recovery of the aerial photographs of Ethiopia in the 1930s
Perspectives locales et globales pour la gestion des terres des régions montagneuses du Nord de l'Éthiopie
Cet article de synthèse s'intéresse au passé et au futur de la gestion des terres en Éthiopie, mettant l'accent sur la partie Nord du pays. Comment l'état des sols et des forêts s'est-il modifié au cours du siècle dernier ? Comment ces modifications affectent-elles les moyens de subsistance de la population ? A la fin du XIXe siècle, il existait déjà des ravines de ruissellement au Nord de l'Éthiopie, bien que celles-ci se soient stabilisées vers…
Geomorphology of the Durmitor Mountains and surrounding plateau Jezerska Površ (Montenegro)
The geomorphological map of the northeastern Durmitor Mountains and the plateau Jezerska Površ (1:10,000, 47 km2, Montenegro, Dinaric Alps) was prepared from an intensive fieldwork campaign and remote sensing analysis, and was compiled within a GIS. The basic components of the legend are (i) processes/genesis, (ii) materials, (iii) morphometry/morphography, (iv) hydrography, (v) vegetation and (vi) anthropogenic features. The geomorphological set…
Geomorphology of the Lake Tana basin, Ethiopia
The geomorphological map of the Lake Tana basin (15,077 km2, Nile basin, Ethiopia) presented in this paper was prepared from fieldwork data, maps and satellite data that were processed with a geographic information system (GIS). It contains four major components: (i) hydrography, (ii) morphology and morphometry, (iii) materials and (iv) processes at a scale of 1:500,000. The geomorphological setting of the basin consists of lavas that erupted fro…
Gully development and its spatio-temporal variability since the late 19th century in the northern Ethiopian Highlands
This study validates previous research and indicates important land degradation by gullying in the second half of the 20th century in the Northern Ethiopian Highlands. In recent decades, local communities have however proven that with proper land management, this trend can be reversed. At a regional scale, gully networks are increasingly being stabilized and the landscape is greening. These developments have to be understood within a socio-econom…
Gully development and its spatio-temporal variability since the late 19th century in the northern Ethiopian Highlands
Drylands are areas where evapotranspiration exceeds precipitation during part of or the whole year They cover 40% of the Earth's surface and house about 2.1 billion people in nearly roo countries, including Ethiopia (UNEP-DDD, 2012). In terms of aridity, dry lands are defined as regions where the ratio between long-term annual precipitation and potential evapotranspiration between 0.05 and 0.65. They include hyperarid, arid, semi-arid and dry sub…
