Agroforestry can increase the sequestration of carbon (C) in soils of tropical agroecosystems through increased litter and tree pruning inputs. Decomposition of these inputs is a key process in the formation of soil organic matter and in nutrient cycling. Our objectives were to study decay of tree pruning mulch and effects on soil C and N in a shaded coffee agroecosystem in Hawaii. Chipped tree...

The deterioration of ecological situation with serious soil and water loss in black soil region of northeast China has attracted more attention due to its significant role on food security of China. To investigate the temporal characteristics of ecological status in typical black soil areas, Baiquan County is selected. Based on the model of Press-Status-Response (P-S-R), indicators are establis...

Water erosion is a natural fact in the cycle of shaping earth’s landforms and most evident form of land degradation on a planetary scale (Roose & De Noni, 2004; Dautrebande Sohier, 2006; Toumi et al., 2013; Azaiez, 2020a). Its effects have largely affected rural landscape. Although it result of an ancient primeval climatic tectonic forcing, man’s footprint its intensification remains reali...

Various methods were utilized for assessment of soil consumption patterns and trends in the cities of Central Europe within Urban Soil Management Strategy (URBAN-SMS) project. They included ex-post assessment of soil loss based on land use change data, modeling of future soil loss and participatory impact assessment. The major data inputs for ex-post and ex-ante assessments were satellite image...

The intensive use of Prince Edward Island (PEI) farmland for potato (Solanum tuberosum L.) production draws concern because of soil physical degradation under the intense tillage and other heavy traffic associated with the mechanisation of this crop, and the resulting vulnerability of sloping fields to hydraulic erosion. Growing public consciousness and pressure in favour of sustainable agricul...

The risk of water erosion is one of the main environmental concerns in the southern Mediterranean regions. Thus, quantification of soil loss is an important issue for soil and water conservation managers. The objective of this paper is to examine the applicability of the Soil and Water Assessment Tool (SWAT) model in The Sarrath river catchment, North of Tunisia, and to identify the most vulner...
