“…On one hand, some authors have shown that traditional tillage leads to high erosion rates and can be even more damaging than climate change itself. 30 On the other hand, cover crops can reduce the susceptibility of the soil to sealing by improving soil quality, 31 and can potentially affect the characteristics of must and wine, 32 according to the concept of terroir.…”

The study of alternative soil managements to tillage, based on the evidence of climate change in the Mediterranean basin, is of great importance. Summer and autumn are critical seasons for soil degradation due to the high-intensity, short-duration storms. Vineyards are vulnerable, especially on steep slopes. The particular effects of storms over the years under different soil conditions due to different management practices are not frequently addressed in the literature. The aim of this study was to examine the differences between runoff and soil moisture patterns influenced by 2 treatments: traditional tillage (Till) and a permanent cover crop. A shallow-rooted grass species Brachypodium distachyon (L.) P. Beauv. with considerable density coverage was selected as cover crop. This annual species was seeded once in the first year and then allowed to self-seed the following years. Tillage was performed at least twice in spring to a 10- to 15-cm depth and once in late autumn at a depth of 20 to 35 cm. Rainfall simulation experiments were performed, 1 year after treatments, using high-intensity rainfall on closed plots of 2 m2, located in the middle strips of the vineyard with different treatments. The effects of simulated rainfall experiments were determined in 3 different moments of the growth cycle of cultivar: (1) in summer with dry soils, (2) in early autumn with moderate soil moisture, and (3) in autumn with wet soils. During the 2-year trial, the soil moisture level in the soil upper layer (0-10 cm) was higher for Till treatment (14.1% ± 2.4%) compared with that for cover crop treatment (12.3% ± 2.0%). However, soil moisture values were more similar between treatments at 35 cm depth (12% ± 1%), with the exception of spring and autumn; in spring, water consumption in the cover crop treatment was the highest, and the moisture level at 35 cm depth was reduced (12%) compared with that for Till treatment (13%). In autumn, in cover crop treatment, higher water infiltration rate in soils led to higher soil moisture content at 35 cm (11%) compared with that of Till treatment (10%). The effects of simulated rainfall experiments on runoff and infiltration under different soil conditions and management practices vary seasonally. Runoff was significantly higher in summer for cover crop treatment (11%) as compared with that for Till management (1%), but significantly lower (3%) with wetter soils than for Till treatment (22%) in autumn. Thus, the simulation experiments with wet soils using cover crops produced higher infiltration rates and, consequently, the higher soil moisture content in the following days. The difference between seasons is attributed to the greater porosity of soil under Till treatment in summer, which resulted from the shallow plowing (10-15 cm depth), carried out to reduce moisture competition between weeds. The effect of traditional spring plowing was short-lived. The infiltration of water increased by cover crop treatment as compared with tillage in autumn both before and after ripping. Management practices did not influence wine parameters, as no significant differences were found between wine organoleptic characteristics in the duo-trio wine tastings, similarly, no differences were found for alcoholic degree, acidity, reduced sugars, and pH; however, a trend for a positive increase in polyphenol contents was noticed. Therefore, properly managed to avoid water shortages, cover crops can be recommended for soil protection in semi-arid environments.

Abstract. China, among other countries, suffers severe soil loss. Water erosion studies in China have been conducted since 1922, and great achievements have since been obtained. Promoting water erosion research in China and globally requires a systematic review of water erosion studies in China. This paper reviews the history, major achievements of water erosion research in China as well as its influencing factors, water erosion processes, changing mechanisms, sediment source identification, global changes, and water erosion impacts on water pollution and crop yield, and research needs in future water erosion study. Threshold slope lengths and water erosion gradients must be considered in hydrologic/erosion models to accurately estimate water erosion. Sedimentation information has been well-mined using chronological tracers and rainfall characteristics in China, which help offset the lack of monitored data in understudied regions. Physical water erosion models that have been well developed in China however should be programmed, promoted, and continuously updated to promote global accessibility. Tracers are used to estimate water erosion, and the efficiency of elemental selection and result confirmation is significant when fingerprinting methods are used to identify sediment sources. Climate change and land use models should be coupled with water erosion models to predict global change impacts on water erosion. In future water erosion research, extreme rainstorm impact on water erosion, water erosion impact on crop yield, smart soil and water conservation, and ecological service-oriented water erosion in China should be evaluated in depth. This review is intended to present water erosion research over approximately 100 years in China to provide future directions and highlight the need for ongoing water erosion research in China and other countries.

“…Para monitorar e avaliar temporalmente e espacialmente a variação de perda de solos em uma determinada área, são utilizados amplamente modelos de previsão de erosão hídrica ao redor do mundo (Eekhout et al, 2021). Considerando que o monitoramento da erosão do solo exige demasiado tempo e auxílio financeiro, a modelagem pode ser realizada por investigação remota, não apenas representando as condições atuais, mas também auxiliando na previsão de possíveis cenários para o século XXI (Zare et al, 2016;Luetzenburg et al, 2020). Os impactos potenciais das mudanças climáticas sobre a erosão do solo podem ser avaliados inserindo diversos dados, como os tipos de solos, os usos da terra, as práticas de manejo e conservação, a declividade das vertentes, o comprimento de rampa, a erosividade da chuva (será discutida adiante) e a erodibilidade do solo, entre outros.…”

Os efeitos das mudanças climáticas na erosividade possivelmente afetarão os processos erosivos no século 21, tornando emergente a discussão dessa temática. Sendo assim, os objetivos desta revisão de literatura são: traçar as relações entre a variação de perda de solos e erosividade diante de mudanças climáticas, apresentando produtos cartográficos das décadas passadas e para todo o século 21; apresentar um panorama geral de pesquisas (publicadas entre 2016-2020); e demonstrar quais são os desafios e próximos passos na pesquisa sobre esta temática. Para tanto, a pesquisa de artigos foi realizada nas plataformas do Portal de Periódicos da CAPES, Google Scholar e Science Direct, totalizando 33 artigos. Foram consideradas pesquisas de natureza conceitual, com revisões de literatura sobre os temas e de natureza procedimental com cálculos do fator R e estimativas de perda de solos. Os trabalhos consultados mostram que a erosividade estimada e a taxa de perda de solos devem aumentar e diminuir em função das futuras mudanças climáticas. Embora, em escala global, haja estimativas do aumento de erosividade para a área tropical do planeta, atingindo majoritariamente países em desenvolvimento como o Brasil. Isso demonstra a emergência da elaboração de estudos para o país, em escala regional, de bioma e de bacias hidrográficas. Nesse sentido, ressaltamos a importância da abordagem sistêmica, que pode ser proporcionada pela Geografia nos estudos desta temática, visto que os desafios se relacionam a dificuldade de integrar diversos fatores ambientais e obter dados de campo nas modelagens preditivas de perda de solo. Overview of Changes in Rainfall and Erosion Patterns in the Face of Climate Change: Literature Review A B S T R A C TThe effects of climate change on erosivity are likely to affect erosion processes in the 21st century, which makes the discussion emerging. Thus, the goals of this literature review are: to trace the relationship between the variation in soil loss and erosivity in the face of climate change, presenting cartographic products from the past decades and for the entire 21st century; present an overview of research (published between 2016-2021); demonstrate challenges and next steps in research on this topic. Therefore, the search for papers was carried out on the platforms of the CAPES Journal Portal, Google Scholar and Science Direct, totaling 78 papers. Conceptual researches was considered, with literature reviews on the themes and procedural researches with calculations of the R factor and soil loss estimate. The consulted papers show that the estimated erosivity and the rate of soil loss are expected to increase and decrease as a result of future climate changes. Although, on a global scale, there are estimates of the increase in erosivity for the tropical area of the planet, mainly affecting developing countries like Brazil. This demonstrates the emergence of studies for the country, on a regional scale, of biomes and hydrographic basins. In this sense, we emphasize the importance of the systemic approach, which can be provided by Geography in the studies of this theme, since the challenges are related to the difficulty of integrating various environmental factors and obtaining field data in predictive models of soil loss.Keywords: erosivity, extreme precipitation events, global climate models
