After the successful mapping of gully erosion channels in the 2018 Eurostat Land Use/Cover Area Frame (topsoil) statistical survey (LUCAS, n = 24,759 locations), the methodology was further expanded across the full LUCAS 2022 survey (n = 399,591 locations). This expert-based assessment identifies the presence or absence of gully erosion forms at each LUCAS location. Its goal is to improve understanding of gully erosion geography in the EU and develop forecasting methods to support soil health indicators proposed by the new Directive on Soil Monitoring and Resilience (COM(2023)416) and Common Agricultural Policy monitoring. Here, we present the findings of our analysis which led to the development and validation of the LUCAS Gully Erosion Model (GE-LUCAS v1.1), a pan-European inventory of gully erosion channels comprising 3,116 locations (~0.8% of all monitored locations) affected by gully erosion throughout the European Union. We further present gully erosion patterns and provide insights on how GE-LUCAS v1.1 inventory can be used to estimate the probability of gully occurrence in areas beyond the monitored locations.

Permafrost degradation is accelerating across the Arctic, posing growing risks to cultural heritage (CH) sites. This study presents the first archipelago-scale hazard assessment of CH to retrogressive thaw slumps (RTS) and thermo-erosion gullies (TEG) in Svalbard, one of the fastest-warming regions globally. By overlaying recent RTS and TEG inventories with the spatial distribution of protected CH sites, we quantify hazard exposure for 55.

Large urban gullies cause damage in many tropical cities across the Global South. They can result from inappropriate urban planning and insufficient infrastructure to safely store and evacuate rainfall in environments that are already highly sensitive to soil erosion. Although they can cause large destruction and societal impacts such as population displacement, the magnitude of this geo-hydrological hazard remains poorly documented and understood.

The distribution of land use types is a comprehensive reflection of natural conditions and human activities, which affects the process of runoff and sediment transport by changing the surface morphology, and then affects the process of soil erosion. Based on the land use data in the Kuye River Basin from 2010 to 2020, this study uses the PLUS model to predict the land use distribution in 2025 under three scenarios and evaluates the soil erosion intensity from 2010 to 2025 on CSLE model, so as to explore the impact of land use change on soil erosion. The results showed that: ① From 2010 to 2020, the land use distribution in the Kuye River Basin was dominated by grassland and farmland.

The Sub-Saharan African region is experiencing the effects of climate change and rapid population growth. The current population, together with the impacts of climate change, has a negative effect on soil resources; hence, implementing land conservation and sustainable land management methods is essential throughout the region. Policymakers require spatial information on soil erosion hotspots to make decisions because soil erosion has high negative impacts on agricultural lands.

As a sedimentary marker of high-energy fluid transport, the mudball formation mechanism is of great significance to the erosion process during extreme climate events. This study uses the extreme rainfall event in Dingbian County of the Loess Plateau in 2022 as a research context. Through integrated approaches including drone imagery and in situ measurements, we systematically investigated the sedimentary characteristics and dynamic processes of mudballs in several small watersheds, focusing on the three-phase mechanism of gravitational erosion, such as mudflow transport and dynamic sorting.
