Remote sensing reveals how armed conflict regressed woody vegetation cover and ecosystem restoration efforts in Tigray (Ethiopia) Ghent University
In recent years, armed conflicts are globally on the rise, causing drastic human and environmental harm. The Tigray war in Ethiopia is one of the recent violent conflicts that has abruptly reversed decades of ecosystem restoration efforts. This paper analyzes changes in woody vegetation cover during the period of armed conflict (2020–2022) using remote sensing techniques, supplemented by field testimony and secondary data. Extent of woody ...
Multi-method monitoring of a failing rock face, Swiss Alps Ghent University
Estimating the runoff response from hillslopes treated with soil and water conservation structures in the semi-arid Ethiopian highlands : is the curve number method applicable? Ghent University KU Leuven
Planning and management of water resources is crucial to enhance agricultural productivity and ensure food security in drylands. For this, adaptable and reliable runoff prediction models are urgently needed to support water harvesting and irrigation development. In this study we explored the potential of the runoff Curve Number (CN) method to estimate daily surface runoff from representative land use types and management conditions in Tigray ...
Assessing catchment connectivity dynamics in the Gumara and Rib catchments of the Ethiopian Highland Ghent University
In the past three decades, the Gumara and Rib catchments in the Ethiopian Highland have witnessed substantial changes in sediment dynamics. These changes are primary driven by alterations in land cover and variation in rainfall patterns. Understanding the mechanisms behind these shifts and their implications for environmental sustainability is important. This study aimed to investigate the dynamics of water and sediment connectivity in two ...
Armed conflict in Tigray sets back decades of ecosystem restoration efforts Ghent University
In recent years, armed conflicts are globally on the rise, causing drastic human and environmental harm. The Tigray war is one of the recent violent conflicts that has abruptly reversed decades of ecosystem restoration efforts. Although field-based investigation into the level of damage is complicated by access and safety issues, recent advances in earth observation tools create room to examine these changes. We analyzed changes in woody ...
Convective rain over the Ethiopian highlands : orographic driving factors in a convection-permitting climate simulation Ghent University
While the Ethiopian highlands constitute over 90% of the population and total area suitable for agriculture, livelihood of 66% of the population depends on subsistence rainfed agriculture. Small rainfall variability could therefore cause massive economic loss. This work aims at understanding the sub daily distribution of average and extreme summer rain over the Ethiopian highlands using the ALARO-0 regional climate model at convection-permitting ...
The status of small-scale farming during the Tigray War (Ethiopia) : evidence on the ground Ghent University
Tree-based ecosystem services supply and multifunctionality of church forests and their agricultural matrix near Lake Tana, Ethiopia Ghent University KU Leuven
Ecosystem services (ES) are the connection between nature and society, and are essential for the well-being of local communities that depend on them. In Ethiopia, church forests and the surrounding agricultural matrix supply numerous ES. However, the ES delivered by both land use types have not yet been assessed simultaneously. Here we surveyed both church forests and their agricultural matrices, aiming to quantify, compare and unravel the ...
