“…Farmers attempt to combat soil erosion with the use of herbicides in summer and limiting ploughing during the remainder of the year (Blavet et al, 2009), although to overcome soil erosion more efforts must be made to incorporate reduced tillage systems. Nevertheless, slope steepness can be partially compensated for by the presence of many stones on the soil surface (sometimes representing almost 100% of soil cover), which increases infiltration and the soil moisture content (Arnáez et al, 2007). Even so, it is relatively common to find rills on convex hillslopes following rainstorms in autumn or spring, and sediment patches at the lower end of plots.…”

Intense erosion processes are widespread in the Mediterranean region, and include sheet wash erosion, rilling, gullying, shallow landsliding, and the development of large and active badlands in both subhumid and semi-arid areas. This review analyses the main environmental and human features related to soil erosion processes, and the main factors that explain the extreme variability of factors influencing soil erosion, particularly recent land use changes. The importance of erosion in the Mediterranean is related to the long history of human activity in a region characterized by low levels of annual precipitation, the occurrence of intense rainstorms and long-lasting droughts, high evapotranspiration, the presence of steep slopes and the occurrence of recent tectonic activity, together with the recurrent use of fire, overgrazing and farming. These factors have resulted in a complex landscape in which intensification and abandonment, wealth and poverty can co-exist. The changing conditions of national and international markets and the evolution of population pressure are now the main drivers explaining land use changes, including farmland abandonment in mountain areas, the expansion of some subsidized crops to marginal lands, and the development of new terraces affected by landslides and intense soil erosion during extreme rainstorm events. The occurrence of human-related forest fires affecting thousands of hectares each year is an increasing problem in both the northern and southern areas of the Mediterranean basin. Here, we highlight the rise of new scientific challenges in controlling the negative consequences of soil erosion in the Mediterranean region: (i) to reduce the effects and extent of forest fires, and restructure the spatial organization of abandoned landscapes; (ii) to provide guidance for making EU agricultural policy more adapted to the complexity and fragility of Mediterranean environments; (iii) to develop field methods and models to improve the identification of runoff and sediment contributing areas; (iv) to contribute to the conservation of landscapes (i.e. bench-terraced fields) having high cultural and productivity values; (v) to improve knowledge of the hydrological and geomorphological functioning of badlands, with the aim of reducing sediment yield and accessibility; (vi) to better understand the effect of climate change on soil erosion in the Mediterranean region; and (vii) to improve quantitative information on long-term soil erosion.

“…Among the cultivated lands, Mediterranean vineyards are recognized to be affected by high soil erosion rates because of a combination of natural and anthropogenic factors (Brillante et al, 2015;Cerdà and Doerr, 2007;Cerdan et al, 2002Cerdan et al, , 2010Martínez-Casasnovas and Sánchez-Bosch, 2000;Raclot et al, 2009). The main reason for their high erodibility are practices that keep the soil between the vines bare during the entire year (Arnáez et al, 2007;Lasanta and Sobrón, 1988) and these bare surfaces are affected by intense storms that induce severe water erosion and runoff processes (Borga et al, 2011;Poesen and Hook 1997;Santos, 2000). Moreover, vineyards are often planted on steep-sloping soils (Arnáez et al, 2007;Wichereck, 1993) with poor nutrient and organic matter content (Cerdà, 1996;Corti et al, 2011;Novara et al, 2011Novara et al, , 2013.…”

“…The occurrence of runoff, and consequently, of material transport by erosion, depends on the rainfall volume and intensity, soil water infiltration, surface storage capacity (Cogo, 1981;Battany & Grismer, 2000;Arnáez et al, 2007;Boulal et al, 2011), and terrain slope, among others. However, the water storage capacity of the soil surface depends almost exclusively on the surface roughness (Cogo, 1981;Kamphorst et al, 2000;Alvarez-Mozos, 2011).…”

SUMMARYThe soil surface roughness increases water retention and infiltration, reduces the runoff volume and speed and influences soil losses by water erosion. Similarly to other parameters, soil roughness is affected by the tillage system and rainfall volume. Based on these assumptions, the main purpose of this study was to evaluate the effect of tillage treatments on soil surface roughness (RR) and tortuosity (T) and to investigate the relationship with soil and water losses in a series of simulated rainfall events. The field study was carried out at the experimental station of EMBRAPA Southeastern Cattle Research Center in São Carlos (Fazenda Canchim), in São Paulo State, Brazil. Experimental plots of 33 m² were treated with two tillage practices in three replications, consisting of: untilled (no-tillage) soil (NTS) and conventionally tilled (plowing plus double disking) soil (CTS). Three successive simulated rain tests were applied in 24 h intervals. The three tests consisted of a first rain of 30 mm/h, a second of 30 mm/h and a third rain of 70 mm/h. Immediately after tilling and each rain simulation test, the surface roughness was measured, using a laser profile meter. The tillage treatments induced significant changes in soil surface roughness and tortuosity, demonstrating the importance of the tillage system for the physical surface conditions, favoring water retention and infiltration in the soil. The increase in surface roughness by the tillage treatments was considerably greater than its
