<p>Soil erosion by water is one of the most important degradation processes. Land use has important effects on soil properties, therefore it is key to identify the type of management that have more impacts and find solutions to mitigate it. In order to understand the effects of land use management on soil and soil erosion in the Istria region (Croatia), we studied the impacts of different agriculture practices (vineyard, cropland, and olive orchard) on soil properties and runoff. The simulated rainfall was carried out at 58 mm h<sup>−1</sup> in the summer of 2018 (30% soil water content) for 30 min on 0.785 m<sup>2</sup> circular plots. The results showed that bulk density was significantly higher in cropland plots than in the vineyard and olive orchard. Soil organic matter, mean weight diameter, and aggregate stability were significantly higher in olive orchard plots than in the vineyard and cropland. Runoff and sediment losses were higher in olive orchard compared to vineyard plots. Carbon, nitrogen, and phosphorus losses were highest in olive orchard plots with 3.9 kg ha<sup>-1</sup>, 405.2 g ha<sup>-1</sup> and 73.6 g ha<sup>-1</sup>, respectively, while lower values were measured in the vineyard plots, where nutrients losses were lower with 0.9 kg ha<sup>-1</sup>, 73.8 g ha<sup>-1</sup> and 6.5 g ha<sup>-1</sup>, respectively. No runoff was observed in cropland plots. Even with the highest measured values of runoff and erosion in the herbicide treated olive orchard, results indicate that both herbicide application and tillage represent a threat to the sustainability of Istrian soils. Vegetation cover on cropland reduces the runoff generation indicating the need for adoption of conservation strategies. In current management, vegetation removal should be avoided since it contributes to practice to reduce nutrient losses and increase the sustainability of the soils.</p><p> </p><p><strong>Keywords</strong>: Soil water erosion, Soil tillage, Rainfall simulation, Agriculture land management, Mediterranean</p><p> </p><p><strong>Acknowledgements</strong></p><p> </p><p>This work was supported by Croatian Science Foundation through the project "Soil erosion and degradation in Croatia" (UIP-2017-05-7834) (SEDCRO).</p>

O entendimento dos efeitos climáticos e do uso do solo em conjunto é crucial para análise ambiental e prevenções de desastres naturais. O objetivo deste trabalho é analisar a vulnerabilidade à erosão hídrica do solo na bacia hidrográfica do rio Araguaia. Usou-se dados de precipitação (Agência Nacional das Águas); uso e ocupação da terra (Projeto MapBiomas); declividade (Instituto Nacional de Pesquisas Espaciais) e de solo (Empresa Brasileira de Pesquisas Agropecuária) no cálculo de mapas através do geoprocessamento para obter-se a representação da erosão hídrica do solo. A bacia hidrográfica do rio Araguaia caracteriza-se na maior parte por zonas de transição de estabilidade e vulnerabilidade, porém destaca-se as áreas estáveis nas proximidades da foz, regiões críticas á sudoeste (Rio das Mortes), nos limites (leste) do Alto Araguaia, nas partes sudeste e sudoeste do Baixo Araguaia. Na escala climática, a precipitação não apresenta riscos significativos. No entanto, o intenso uso e ocupação da terra na região foi a forçante que maior agravou a vulnerabilidade, principalmente em áreas (declives e solo) naturalmente instáveis. Assim, algumas cidades precisam estar em alerta para possíveis eventos erosivos.     Vulnerability to soil water erosion, Araguaia basin riverA B S T R A C TThe Understanding climate effects and land use together is crucial for environmental analysis and natural disaster prevention. The objective of this work is to analyze the vulnerability to soil water erosion in the hydrographic basin of the Araguaia river. Rainfall data (National Water Agency) was used; land use and occupation (MapBiomas Project); slope (National Institute for Space Research) and soil (Brazilian Agricultural Research Corporation) in the calculation of maps through geoprocessing to obtain the representation of soil water erosion. The hydrographic basin of the Araguaia river is characterized in the most part by transition zones of stability and vulnerability, however the stable areas in the vicinity of the mouth stand out, critical regions to the southwest (Rio das Mortes), on the (eastern) limits of the Alto Araguaia, in the southeast and southwest parts of the Lower Araguaia. On the climate scale, the rainfall does not present significant risks. However, the intense use and occupation of land in the region was the forcing that increased the risk, mainly in naturally unstable areas (slopes and soil). Thus, some cities need to be alert to possible erosive events.

The objective of this study was to analyze the sustainability to water erosion in the Capim river/PA-MA. Acquired precipitation (GPCC), slope (TOPODATA project), land use and land cover data (MapBiomas) and pedology (Brazilian Soil Classification System) were obtained. Based on these variables, in a Geographic Information System environment, the product representing the sustainability to soil water erosion was generated. A sustainability gradient for soil water erosion was observed in the SE-NW direction, where it was higher near the mouth of the Capim River. The other variables were: clinical component presenting predominance of stability and high sustainability in the south of the basin; land use influences the entire axis of the basin, indicating instability in the medium-low Capim and in the extreme southeast. It was observed that the sustainability to erosion in the Capim watershed is motivated by intensified land use near the mouth. The zoning carried out in the basin is a warning sign for the municipalities of São Domingos do Capim, Rondon do Pará and Goianésia do Pará.

The Future

<p>It is well known that the impact of climate change affects various areas such as hydroclimatical factors which can cause increased occurrence of heavy precipitation events, ice melting, rising temperature or sea-level as a consequence of the global warming. It is assumed that the average surface temperature on Earth has increased by more than 1° Celsius since 1880. Climate change of the Earth has changed naturally over the past 650.000 years as a result of external factors that impact the climate. Despite of this fact, over the last 100 years is global warming strongly accelerated by different kind of human activities. One of those activities represents inappropriate land use management which is directly connected with soil degradation and soil erosion as the major threat of global soil degradation. The study presents the assessment of the future development of soil water erosion processes in one small agricultural catchment located in the Slovak Republic. The calculations were done based on the long-term simulation using the event and physically-based soil erosion model and one-hour rainfall events. The model used was calibrated and validated in the previous studies. The period time analysed covers 80 years, i.e., from 2020 until 2100. From the period the years where the most intensive rainfall events have occurred were chosen. The rainfall events were determined by climate CLM model. In order to compare the suitability of land-use management, three scenarios were created. They include three different types of land cover, i.e., agricultural crops (wheat and corn) and grassland. The modelled results show development of soil erosion in the future period up to 2100 together with the comparison of land use management in the area under research. The study predicts the future development of soil water erosion where the short term extreme rainfall events play key element as a crucial factor in the soil erosion assessment processes.</p><p> </p>

Abstract. Snow processes might be one important driver of soil erosion in Alpine grasslands and thus the unknown variable when erosion modelling is attempted. The aim of this study is to assess the importance of snow gliding as a soil erosion agent for four different land use/land cover types in a subalpine area in Switzerland. We used three different approaches to estimate soil erosion rates: sediment yield measurements in snow glide depositions, the fallout radionuclide 137Cs and modelling with the Revised Universal Soil Loss Equation (RUSLE). RUSLE permits the evaluation of soil loss by water erosion, the 137Cs method integrates soil loss due to all erosion agents involved, and the measurement of snow glide deposition sediment yield can be directly related to snow-glide-induced erosion. Further, cumulative snow glide distance was measured for the sites in the winter of 2009/2010 and modelled for the surrounding area and long-term average winter precipitation (1959–2010) with the spatial snow glide model (SSGM). Measured snow glide distance confirmed the presence of snow gliding and ranged from 2 to 189 cm, with lower values on the north-facing slopes. We observed a reduction of snow glide distance with increasing surface roughness of the vegetation, which is an important information with respect to conservation planning and expected and ongoing land use changes in the Alps. Snow glide erosion estimated from the snow glide depositions was highly variable with values ranging from 0.03 to 22.9 t ha−1 yr−1 in the winter of 2012/2013. For sites affected by snow glide deposition, a mean erosion rate of 8.4 t ha−1 yr−1 was found. The difference in long-term erosion rates determined with RUSLE and 137Cs confirms the constant influence of snow-glide-induced erosion, since a large difference (lower proportion of water erosion compared to total net erosion) was observed for sites with high snow glide rates and vice versa. Moreover, the difference between RUSLE and 137Cs erosion rates was related to the measured snow glide distance (R2 = 0.64; p < 0.005) and to the snow deposition sediment yields (R2 = 0.39; p = 0.13). The SSGM reproduced the relative difference of the measured snow glide values under different land uses and land cover types. The resulting map highlighted the relevance of snow gliding for large parts of the investigated area. Based on these results, we conclude that snow gliding appears to be a crucial and non-negligible process impacting soil erosion patterns and magnitude in subalpine areas with similar topographic and climatic conditions.

During the last decades, pastoralist, and agropastoralist populations of the world’s drylands have become exceedingly vulnerable to regional and global changes. Specifically, exacerbated stressors imposed on these populations have adversely affected their food security status, causing humanitarian emergencies and catastrophes. Of these stressors, climate variability and change, land-use and management practices, and dynamics of human demography are of a special importance. These factors affect all four pillars of food security, namely, food availability, access to food, food utilization, and food stability. The objective of this study was to critically review relevant literature to assess the complex web of interrelations and feedbacks that affect these factors. The increasing pressures on the world’s drylands necessitate a comprehensive analysis to advise policy makers regarding the complexity and linkages among factors, and to improve global action. The acquired insights may be the basis for alleviating food insecurity of vulnerable dryland populations.

Saltwater intrusion risk assessment is a foundational step for preventing and controlling salinization in coastal regions. The Vietnamese Mekong Delta (VMD) is highly affected by drought and salinization threats, especially severe under the impacts of global climate change and the rapid development of an upstream hydropower dam system. This study aimed to apply a modified DRASTIC model, which combines the generic DRASTIC model with hydrological and anthropogenic factors (i.e., river catchment and land use), to examine seawater intrusion vulnerability in the soil-water-bearing layer in the Ben Tre province, located in the VMD. One hundred and fifty hand-auger samples for total dissolved solids (TDS) measurements, one of the reflected salinity parameters, were used to validate the results obtained with both the DRASTIC and modified DRASTIC models. The spatial analysis tools in the ArcGIS software (i.e., Kriging and data classification tools) were used to interpolate, classify, and map the input factors and salinization susceptibility in the study area. The results show that the vulnerability index values obtained from the DRASTIC and modified DRASTIC models were 36–128 and 55–163, respectively. The vulnerable indices increased from inland districts to coastal areas. The Ba Tri and Binh Dai districts were recorded as having very high vulnerability to salinization, while the Chau Thanh and Cho Lach districts were at a low vulnerability level. From the comparative analysis of the two models, it is obvious that the modified DRASTIC model with the inclusion of a river or canal network and agricultural practices factors enables better performance than the generic DRASTIC model. This enhancement is explained by the significant impact of anthropogenic activities on the salinization of soil water content. This study’s results can be used as scientific implications for planners and decision-makers in river catchment and land-use management practices.
