Overland flow connectivity and runoff and sediment trap effectiveness are currently the cutting edge topics in soil erosion research. The effect of agricultural terraces, irrigation channels and trails on runoff and soil erosion modelling at catchment scale is still a remaining research question. In this study we run the index of connectivity of Borselli et al. (2008) and a modified version of ...
The European mountainous areas, such as the Pyrenees, have suffered important land use changes since the beginning of the XX century. These changes affect the plant cover recovery process and then the runoff and sediment production. Soil moisture can be a key factor in the evolution of the abandoned land. It determines the vegetation recovery, runoff generation, sediment detachment and soil dev...
Abstract There are thousands of abandoned mine land (AML) sites in the U.S. that need to be restored reduce wind and water erosion, provide wildlife forage, shade streams, improve productivity. Biochar created from woody biomass would normally burned slash piles can applied soil properties is one method restore AML productive capacity. Using this ‘waste’ for biochar reclamation activities will ...
This paper presents a dynamic systems model that shows how different land use patterns degrade the value of ecosystem services provided by the Brazilian Amazonia. The model consists of four sectors: (1) deforestation drivers; (2) land use/cover; (3) ecosystem services; and (4) ecosystem valuation. The deforestation drivers sector models the economic and social incentives that small farmers and ...
The Indonesian land area is 191.1 million ha, part of which abandoned in various agroecosystems that have the potential for expanding agricultural area. purpose this research was to geospatially analyze based on its agroecosystem at national and district levels, as well evaluate suitability development. methods included: (1) geospatial analysis cover map a scale 1:250,000 combined with soil cli...
Changes in land use might affect the combined C, N and P stoichiometry in soil. The Grain-to-Green Program (GTGP), which converts low-yield croplands or abandoned lands into forest, shrub, and/or grassland, was the largest land reforestation project in China. This study collected the reported C, N and P contents of soil in GTGP zones to achieve the factors driving the changes in the C:N, C:P, a...
Past land use can impart soil legacies that have important implications for ecosystem function. Although these legacies have been linked with microbially mediated processes, little is known about the long-term influence of land use on soil microbial communities themselves. We examined whether historical land use affected soil microbial community composition (lipid profiles) and whether communit...
