Corrigendum to “Carbon emissions and economic assessment of farm operations under different tillage practices in organic rainfed almond orchards in semiarid Mediterranean conditions” [Sci. Hortic. 261 (2020) 108978]
Article
The diagnosis of land degradation requires a deep understanding of ecosystem functioning and evolution. In dryland systems, in particular, research efforts must address the redistribution of scarce resources for vegetation, in a context of high spatial heterogeneity and non-linear response. This fact explains the prevalence of eco-hydrological pers...
Article
The use of check-dams in mountain environments to regulate fluxes of water and sediments is widely applied across Mediterranean mountains. Besides the use of “grey infrastructures” such as check-dams, other restoration and hydrological control measures rely more on the use of “green infrastructures” or “nature-based solutions” (e.g. reforestation,...
Article
The Mediterranean region has been identified as one of the most affected global hot-spots for climate change, which is already manifested by faster increasing temperatures than the global mean and significant decreases in annual precipitation. Besides, over the past decades, important land cover changes have occurred, such as reforestation, agricul...
Article
The importance of sediment connectivity for watershed management needs accurate quantification tools, particularly in Mediterranean torrents, where soil erosion and sediment transport are often not tolerable. This study proposes a modified version (mCCI) of the Catchment Connectivity Index (CCI), theorized by Quiñonero‐Rubio, Boix‐Fayos, and de Ven...
Chapter
Several frameworks to evaluate the sediment connectivity-the physical linkage of sediment through the channel system-in a catchment have been proposed and verified in several environmental contexts. A simple but effective index ("catchment connectivity index", CCI), considering the geomorphological characteristics of the channels and the connectivi...
Article
Sustainable land management practices, such as reduced tillage or crop diversification, are potentially efficient measures to fight against soil degradation and desertification. The decision to approve these practices must be justified by both integrated environmental and economic assessment studies. In this work, we analysed the carbon emissions a...

Land degradation affects natural and cultivated socio-ecosystems worldwide. Soil erosion is one of the main processes leading to land degradation, and the process is accelerated by human actions. Spain is dealing with extensive land degradation caused by land use and land cover change (LULCC), for instance by land abandonment, and local geo-ecologi...
Article
Full-text available
The role of fluvial sedimentary areas as organic carbon sinks remains largely unquantified. Little is known about mechanisms of organic carbon (OC) stabilization in alluvial sediments in semiarid and subhumid catchments where those mechanisms are quite complex because sediments are often redistributed and exposed to a range of environmental conditi...
Article
Full-text available
Anthropic changes in the drainage area of catchments can influence dominant erosion processes and sediment sources and mobilize specific carbon pools. It also causes changes in the sedimentary dynamics and thus in the fluvial morphology. At the same time fluvial morphologies can create the conditions for stabilizing organic carbon (OC) in sediments...

Terrestrial sedimentation buries large amounts of organic carbon (OC) annually, contributing to the terrestrial carbon sink. The temporal significance of this sink will strongly depend on the attributes of the depositional environment , but also on the characteristics of the OC reaching these sites and its stability upon deposition. The goal of thi...
Article
Soil erosion processes play an important role in the redistribution of soil organic carbon over the landscape. The factors controlling this carbon (C) redistribution have been thoroughly studied at the plot scale, but knowledge at the landscape level is still limited. In this study, we explore the role of different factors on C export at the catchm...
Article
Reforestations and check-dams are two commonly used measures to reduce soil erosion rates and sediment export from highly eroding catchments. Here we evaluated the impact of the construction of 94 check-dams and land use changes (caused by agricultural abandonment and reforestations) on sediment yield in the Upper Taibilla catchment (320 km2, SE-Sp...

With the purpose of analysing the type (labile or stable) and quantity of organic carbon (OC) mobilized by different erosive processes identified at the slope-bed connection, the erosion deposits of gullies, sheet erosion, bank erosion and tillage erosion were studied in a small catchment (10 ha) and compared to the characteristics of the catchment...
Article
During the last decade, many studies have been conducted to assess the role of soil erosion in the terrestrial carbon cycle. The reported results suggest that erosion can enhance organic carbon oxidation upslope in an eroding watershed, while, at the same, time, leading to greater soil organic carbon (SOC) storage downslope. Soil erosion can lead t...

Soil organic carbon (OC) mobilization due to erosional processes can have consequences regarding CO2 emission or sequestration. OC can be mineralized (emitted as CO2 to the atmosphere) during detachment, transport and deposition of soil particles, or buried in depositional settings, where it can also be stabilized. The contradicting results in the...
Article
A wide range of soil organic carbon (OC) erosion rates have been reported around the world (~0.0005-3 t ha-1 yr-1). Up to date, factors affecting organic carbon mobilization have been assumed to operate parallell to those of soil erosion, linking OC to the soil fine fraction, and studies have been conducted mainly in agricultural sites and on fine...
