“…Moreover, sensitivity of soils to land use change is also affected by geographical factors, morphological factors and other site specific properties. For instance, a land use change from forest to grassland has a drastically different effect on soil erosion risk and, to a greater extent, on soil hydraulic properties for a hilly/mountainous area compared to an area located in a plain [19,21]. Similarly, the effect of management practices involving agricultural land, i.e., the sensitivity of the site for erosion caused by tillage, can also vary among sites depending on exposure to wind and water erosion [44].…”

“…Vegetation cover is often considered a major factor in controlling soil processes [15][16][17][18]. Vegetation density [19] and types play key role in modifying runoff and soil erosion [20,21]. Changes in vegetation can occur due to anthropogenic activities, such as changes in agricultural cultivation practices or deforestation, or due to natural sources like wildfire.…”

Soil hydraulic properties are among the most important parameters that determine soil quality and its capability to serve the ecosystem. Land use can significantly influence soil properties, including its hydraulic conditions; however, additional factors, such as changes in climate (temperature and precipitation), can further influence the land use effects on soil hydraulic properties. In order to develop possible adaptation measures and mitigate any negative effects of land use and climatic changes, it is important to study the impact of land use and changes in land use on soil hydraulic properties. In this paper, we summarize recent studies examining the effect of land use/land cover and the associated changes in soil hydraulic properties, mainly focusing on agricultural scenarios of cultivated croplands and different tillage systems.

“…The reduction of vegetation cover can increase soil erosion. This relationship is the reason why vegetation cover and land use have been widely included in soil erosion studies [23][24][25][26][27][28]. Previous studies have found that land use can greatly affect the intensity of runoff and soil erosion [24,29,30].…”

This paper evaluates the possible impacts of climate change and land use change and its combined effects on soil loss and net soil loss (erosion and deposition) in the Mae Nam Nan sub-catchment, Thailand. Future climate from two general circulation models (GCMs) and a regional circulation model (RCM) consisting of HadCM3, NCAR CSSM3 and PRECIS RCM ware downscaled using a delta change approach. Cellular Automata/Markov (CA_Markov) model was used to characterize future land use. Soil loss modeling using Revised Universal Soil Loss Equation (RUSLE) and sedimentation modeling in Idrisi software were employed to estimate soil loss and net soil loss under direct impact (climate change), indirect impact (land use change) and full range of impact (climate and land use change) to generate results at a 10 year interval between 2020 and 2040. Results indicate that soil erosion and deposition increase or decrease, depending on which climate and land use scenarios are considered. The potential for climate change to increase soil loss rate, soil erosion and deposition in future periods was established, whereas considerable decreases in erosion are projected when land use is increased from baseline periods. The combined climate and land use change analysis revealed that land use OPEN ACCESSSustainability 2013, 5 3245 planning could be adopted to mitigate soil erosion and deposition in the future, in conjunction with the projected direct impact of climate change.

“…Because vegetation cover can effectively prevent soil erosion, more research on the relationship between vegetation and soil erosion has recently been conducted. Nearly all of these studies have found a negative relationship between vegetation coverage (VC) and soil erosion (Marques et al, 2007;Zhou et al, 2008). The negative correlation usually extends from a linear (Greene et al, 1994) to an exponential (Marston, 1952) correlation.…”

Vegetation effectively prevents soil erosion. However the relationship between plant diversity and soil erosion remains ambiguous under various environmental conditions. To explore the role that plant diversity plays in soil erosion, this study was conducted in the Three-River-Source region, located in the hinterlands of the Qinghai-Tibet Plateau, China. After examining 99 plots within the study area, and analyzing the soil 137 Cs inventory within the plots, we found that with a greater number of plants distributed within an aggregation pattern, there was greater interception of the soil particles by the vegetation patch. This phenomenon results in a more developed vegetation patch that can support greater vegetation coverage and higher plant diversity than it previously could. Although a positive correlation exists between plant diversity and vegetation coverage, the relationship between the extent of soil erosion and plant diversity is modulated by the vegetation pattern. When plants are distributed in a relatively homogeneous pattern, vegetation coverage decreases with increasing plant diversity, which leads to increased soil erosion. When plants are distributed between a homogenous and a heterogeneous pattern, no relationship is found between plant diversity and soil erosion. With a heterogeneous plant distribution, vegetation coverage increases with plant diversity, and soil erosion is inhibited under such conditions.
