Abstract In March 2020, an extreme rainfall in Baixada Santista, Brazil, led to a series of landslides affecting more than 2,800 people and resulting losses exceeding USD 43 million. This attribution study compared two distinct runs from the UK Met Office Hadley Centre HadGEM3-GA6 model: one with all forcings other natural only, considering antecedent conditions soil moisture (extreme 60-day rainfall, Rx60day) heavy 3-day Rx3day) which may trigger landslides. The long-term set-up became 74% likely, while short-term was 46% likely. anthropogenic contribution changes accounted for 20-42% total damages. greatest economic occurred Guarujá (42%), followed by São Vicente (30%) Santos (28%).

ABSTRACT This study aimed to assess the feasibility of using common gorse (Ulex europaeus) produce weaving meshes for soil protection and revegetation. species was imported several years ago creating natural fences. However, due its easy propagation, generates negative impacts on Colombian moor ecosystems. Hence, governmental agencies are struggling with eradicating this shrub, generating lot waste additional costs. Thus, add value, proposed as an alternative transform such develop open weave fibers extracted from shrub stem. In doing so, first stems were characterized define potential uses. involved physical mechanical tests that evaluate performance in laboratory, simulating field exposure conditions contact water. Results showed that, through fiber extraction, 60% reuse achieved when mature stages. accounted a reliable behavior.

Soil erosion varies in space and time. As the contributing surface area increases, heterogeneity effects are amplified, inducing scale effects. In present study, soil processes as affected by observation conditions assessed. An experimental field setup of 18 plots (1–150 m2) with different (bare degraded, cultivated) slopes (0.75–4.2%) used to monitor losses between 2010 2018 under natural rainfall. The results showed that loss rates range 2.5 19.5 t.ha−1 cultivated increase 12–45 on bare degraded soils, which outlines control erosion. At a larger (38 km2), estimated at 2.2–4.5 t.ha−1, highlighting major contribution scale. effect is likely caused redistribution sediments drainage network. These findings outline nature emerging dominant scales. plot scale, however, diffuse remains dominant, since runoff laminar sediment transport capacity limited, resulting lower rates.

The estimation of rainfall erosivity in the Revised Universal Soil Loss Equation (RUSLE) requires long series sub-hourly observations. Due to endemic unavailability this information, at least with required degree detail and coverage, empirical models are frequently used for basing on easily retrievable values monthly or annual scale. In paper, an model is calibrated Italy bridge scale gap by means 10-year observations 171 Italian rain gauges, then applied using ERA5-Land gridded dataset obtain maps seasonal covering reference period 1981–2010.

The Rolling Hilly Region of Northeast China (RHRNEC) is a critical grain production area in China, and soil erosion major problem this region. To determine spatial temporal changes rainfall erosivity (RE) the RHRNEC generate information useful for water conservation, agricultural management, ecological protection efforts, RE index consisting nine indices based on normal extreme precipitation was established. (NREI) comprised annual (ARE), wet season (WRE), dry (DRE), typical wet-month (TWRE), dry-month (TDRE), set (EREI) maximum one-day (RE × 1 day), five consecutive days 5 storm (RE50), continuous (CRE). ARE, WRE, TWRE decreased at relative rates 2.5%, 2.9%, 4.1%, respectively. By comparison, DRE increased non-significant rate 6.3%, all to 1981–2015 mean values. future trends were predicted be opposite historical trends. exhibited patterns. gradually from north south, DRE, significantly negatively correlated with longitude, latitude, altitude (p < 0.05). showed increasing south decreasing center. findings are especially management protection.
