Due to war conditions, the local farmers had to largely rely on their own crop production, mainly by subsistence farming, in Tigray, North Ethiopia. We assessed the crop stands in 2021 and evaluated the level of resilience of the indigenous farming system. Quantitative data were collected from 161 farm parcels in various ecoregions of this tropical...

Knowledge of hydrologic connectivity is important to grasp the hydrological response at a basin scale, particularly as changes in connectivity can have a negative effect on the environment. In the context of a changing climate, being able to predict how changes in connectivity will affect runoff and sediment transport is particularly relevant for l...
Conference Paper
Full-text available
In early November 2020, after months of growing political tensions, an armed conflict emerged between the Ethiopian government and the Tigray regional government. As the conflict arose in the wake of a destructive locust invasion and in addition to the covid-19 pandemic, it was soon realized that the conflict would have a major impacts on the popul...

In view of our geographical research expertise in the tropical mountains of Tigray (north Ethiopia) since 1994, our focus was deflected from geomorphology and environmental management to casualty recording and survival strategies, after the Tigray War started in November 2020. We created the "Atlas of the Humanitarian Situation", in which we chroni...
Article
Military conflicts strongly affect agricultural activities. This has strong implications for people’s livelihoods when agriculture is the backbone of the economy. We assessed the effect of the Tigray conflict on farming activities using freely available remote sensing data. For detecting greenness, a Normalized Difference Vegetation Index (NDVI) wa...
Article
During the 2021 conflict in Tigray (north Ethiopia) crop cultivation has been hampered by warfare. Oxen have been looted and killed, farm inputs and tools destroyed by Ethiopian and Eritrean soldiers. Farmers felt vulnerable out in the open with their oxen. To produce, farmers evaluated risks involved with ploughing and organised lookouts. Overall,...

At the beginning of November 2020, an armed conflict emerged in Tigray, Ethiopia’s northernmost region. The objective of this ‘Atlas of the Humanitarian Situation’ is to document and map the situation in which approximately 6 million Tigrayans currently find themselves. For this, we contacted key informants in different districts of Tigray to colle...
Conference Paper

Conflict has deep historical roots in the horn of Africa, particularly in Ethiopia. Such conflicts often go hand in hand with humanitarian catastrophes including famine and mass-displacement (Annys et al. 2021). The Tigray region of Ethiopia has experienced such conflict induced catastrophes in the 1984/85 (Deckers et al. 2020), and now again (Nyss...
Article
In recent years, a renewed interest in large-scale hydraulic interventions has developed, frequently justified by the premise of making the agricultural and energy sectors climate-resilient. Despite this important climate effort, hydraulic interventions are controversial and have far-reaching impacts on river-dependent communities and the environme...

Collecting field data on 161 sampling sites in very difficult conditions has allowed us to evaluate the status of cropping in part of the Tigray region of Ethiopia, by the end of August 2021. We have observed that local farming communities are remarkably resilient, also in times of conflict and instability. Relying on indigenous knowledge and local...
Article
Based on extensive field information, farmer-led small-scale irrigation systems along the dam-regulated Tekeze River is investigated and the likelihood of future irrigation expansion within the area with modelled potential is discussed, considering facilitating and hampering factors. Due to dam-induced hydrologic alterations, downstream socio-ecolo...
Article
Since fighting broke out in November 2020 between the Tigrayan regional government and the Ethiopian army, the conflict has wreaked havoc on the lives of people living in the Tigray Region of Ethiopia. Over 9,500 civilian deaths have been documented, with many more unrecorded. In addition about 2 million people have been displaced and at least 400,...

Since November 2020, a civil war is taking place in Tigray (north Ethiopia), where about 75% of the active population are farmers. Here, we present the state of ploughing in Tigray’s war conditions, early in the 2021 rainy season and discuss contextual factors. Early May 2021, around Mekelle, very few croplands have been ploughed, as compared to th...
Thesis
In recent years, a renewed interest in large dams and large-scale irrigation schemes has developed, justified by the premise to make the agricultural and energy sectors climate-resilient. Despite this important climate effort, large dams and interbasin water transfers are controversial and have far-reaching impacts for river-dependent communities a...
Article
The 21st century revival of large-scale water resources development projects makes it important to keep assessing their impacts – preferably from an interdisciplinary perspective – in order to not repeat past mistakes and explore whether they could improve livelihood conditions for rural communities. In this study, costs and benefits of the World B...

Due to renewed interest in hydropower dams in the face of climate change, it is important to assess dam operations and management in combination with downstream impacts on rivers in (semi-)arid environments. In this study, the impacts of the Tekeze hydropower dam on downstream hydrology and river morphology were investigated, including impacts unde...

Therelationshipbetweenirrigationwateravailabilityandcroprevenueismultifaceted.However,most of the previous studies focused only on the direct effect of irrigation water on crop revenue or considered that the indirect effect passes only through the farmers’ improved farm inputs usage. Nevertheless, unlike previous studies,this study argues that a on...

Focus: matching agricultural water demand and supply is a growing policy challenge in drylands. We investigated the water balance components in Raya (3507 km 2) and Ashenge (80.5 km 2) grabens. The rainfall depth, river discharge, abstraction, climate and soil data (2015-2017) were used to address the research question. New hydrological insights: t...
Article
Despite public awareness of unintended impacts (1980s) and well-developed international standards (2000s), downstream impacts of large hydropower projects still very often are not properly assessed. Impacts of (hydropower-regulated) interbasin water transfers (IBWTs) are considered self-evidently positive, although they can have far-reaching conseq...

Project
A humanitarian crisis has unfolded in Tigray, the northernmost region of Ethiopia. As professionals with decades of involvement in research and development activities in Tigray, we are saddened to see the gains made after the devastating civil war of the 1980s being wiped away before our eyes. Many citizens have lost their lives, many others are wounded, and people in Tigray and other parts of Ethiopia live in fear that their lives are at great jeopardy. Sexual violence and starvation are widespread.
