Impact of historical land use and soil management change on soil erosion and agricultural sustainability during the Anthropocene

Short communication: Massive erosion in monsoonal central India linked to late Holocene land cover degradation

“…In the absence of historical documentation of human impacts, the complexity of soil erosion hampers the reconstruction of carbon transfer processes prior to the last few centuries (e.g., Hoffmann et al, 2013;Dotterweich, 2013;Vanwalleghem et al, 2017). Consequently, global carbon budgets implicitly assume steady state conditions for lateral transport and carbon degradation along the aquatic continuum in pre-industrial times (Battin et al, 2009;Regnier et al, 2013;Chappell et al, 2016).…”

Long-term changes in alpine pedogenetic processes: Effect of millennial agro-pastoralism activities (French-Italian Alps)

“…However, considering the lack of knowledge concerning soil functioning, no regulatory measures have yet been established to protect soils (Puydarrieux et al, 2016). This lack is related to the complexity of pedogenesis and the feedbacks between erosion, soil properties, vegetation and agricultural management (Johnson and Watson-Stegner, 1987;Richter, 2007;Vanwalleghem et al, 2017), which have strongly varying response times. Soils form slowly from the weathering of rocks and the incorporation of organic matter and are mixed and affected by vertical and horizontal transfers due to hydrological fluxes, bioturbation, slopes, etc.…”

“…Because soils are a non-renewable resource over human timescales (Vanwalleghem et al, 2017), the potential of provided services can be threatened by human activities that trigger erosion and land degradation (Oldeman, 1994;Sabatier et al, 2014;Vanwalleghem et al, 2017). In Europe, the cost of soil degradation has been estimated to be 38 billion € per year (COM EU, 2006).…”

“…Soil erosion must be considered within a long historical context in order to better understand the current drivers of soil degradation processes and their consequences for ecosystem functioning (Trimble and Mendel, 1995;Vanwalleghem et al, 2017).…”

Alterações no ciclo hidrológico e na perda de solo devido aos diferentes usos do solo e variações climáticas em área de Cerrado

“…O comportamento do escoamento superficial, conforme reportado em estudo experimental anterior (Oliveira et al, 2016), teve o solo exposto como a condição que produziu o maior volume de escoamento superficial após um evento de chuva, seguido pela pastagem, cana-de- Fonte: Autor A modelagem a longo prazo do escoamento superficial e da erosão do solo possui a limitação das incertezas relacionadas com as variáveis de entrada dos modelos utilizados nas projeções, que tendem a crescer com tempo (Vanwalleghem et al, 2017). Modelos como o WEPP são mais adequados para tais projeções, pois conseguem reproduzir as interações entre as mudanças na precipitação e temperatura, proveniente dos GCMs, nos fatores que governam o escoamento superficial e a erosão do solo ligados ao uso e manejo do solo.…”
