How to better link landslide inventory mapping with loss and damage reporting
Landslides are inherent multi-hazard events, with different types of triggering mechanisms and due to their widely varying characteristics. Landslides are very underrepresented in global disaster databases, due to their high frequency and relatively low impacts, where individual events might often not pass the threshold for inclusion in the database. As a result, their accumulated effect is underestimated. In relation to the Early Warnings for Al…
Geological and Geomorphological Controls on Landslides
Landslides are geohydrological hazards that shape landscapes and may cause disasters. Despite their impact, the geological and geomorphological factors controlling their occurrence are not always well understood. This is especially so in mountainous areas in tropical regions where environmental conditions, such as bedrock type and soil weathering, may be specific. This research investigates these controls on landslides in the North Tanganyika-Kiv…
Assessing scale reliability in citizen science motivational research
Citizen science (CS) is gaining global recognition for its potential to democratize and boost scientific research. As such, understanding why people contribute their time, energy, and skills to CS and why they (dis)continue their involvement is crucial. While several CS studies draw from existing theoretical frameworks in the psychology and volunteering fields to understand motivations, adapting these frameworks to CS research is still lagging an…
Exposure and physical vulnerability to geo-hydrological hazards in rural environments
Inventories of natural hazards in under-reported regions
Impacts of natural hazards are on an increase globally. To mitigate these impacts, sound disaster risk reduction strategies must rely on comprehensive inventory of natural hazards. However, to date, many regions worldwide still suffer from a dearth of information. The goal of our research is to assess how, with limited means and several methods, environments that are typically under-researched can be covered with accurate information on which fur…
Can citizen scientists provide a reliable geo-hydrological hazard inventory? An analysis of biases, sensitivity and precision for the Rwenzori Mountains, Uganda
Spatio-temporal inventory of natural hazards is a challenging task especially in rural or remote areas in the Global South where data collection at regional scale is difficult. Citizen science, i.e. involvement of no-experts in collecting information and co-creation of knowledge with experts to solve societal and environmental problems, has been suggested as a viable approach to tackle this bottleneck, although the reliability of the resulting da…
Domain Adaptation for Semantic Segmentation of Historical Panchromatic Orthomosaics in Central Africa
Multitemporal environmental and urban studies are essential to guide policy making to ultimately improve human wellbeing in the Global South. Land-cover products derived from historical aerial orthomosaics acquired decades ago can provide important evidence to inform long-term studies. To reduce the manual labelling effort by human experts and to scale to large, meaningful regions, we investigate in this study how domain adaptation techniques and…
Historical dynamics of landslide risk from population and forest-cover changes in the Kivu Rift
Questioning network governance for disaster risk management
Soil erosion in relation to land-use changes in the sediments of Amik Lake near Antioch antique city during the last 4 kyr
The Amik Basin in the Eastern Mediterranean region occupied since 6000–7000 BC has sustained a highly variable anthropic pressure culminating during the late Roman Period when the Antioch city reached its golden age. The present 6-m-long sedimentary record of the Amik Lake occupying the central part of the Basin constrains major paleoenvironmental changes over the past 4000 years using multi-proxy analyses (grain size, magnetic susceptibility, an…
