The Effect of Land use and Soil Erosion on Soil Organic Carbon and Nitrogen Stock
Soil organic carbon (SOC) is a principal component in soil quality assessment. Knowledge of SOC and total nitrogen (TN) stocks are important keys to understand the role of SOC in the global carbon cycle and, as a result, in the mitigation of global greenhouse effects. SOC and TN stocks are functions of the SOC concentration and the bulk density of the soil that are prone to changes, influe...
متن کاملSoil Erosion Under Different Land Use and Cover Types in a Marginal Area of Portugal
According to the CORINE programme, Spain and Portugal are the Mediterranean countries in the European Union facing the greatest risk of erosion (Desir & Marín, 2007). In Portugal, areas at high risk of erosion cover almost one third of the country (Grimm et al., 2002). The main causes of soil erosion are inappropriate agricultural practices, land abandonment, deforestation, overgrazing, forest ...
متن کاملInvestigation of Land Use Change on Physicochemical Characteristics and Soil Erosion in Kaftargar Basin of Behshahr
The land-use change, cutting forest trees and the grasslands conversion to agricultural lands destroyed natural ecosystems and also current or future production capacity reduce and these are harmful effects on the soil physicochemical characteristics. This study taken with aim, checking the role of forest-land change on some soil physical-chemical characteristics and then identify some effectiv...
متن کاملImpacts of Land Use Change on Soil Erosion and Water Quality—A Case Study from Hawaii
The ongoing diversification of agricultural lands in Hawaii to replace sugarcane and pineapple plantations is a major challenge. It presents an interesting case study for global concerns with land degradation-land use interaction. The important question posed by this paper is: will “diversified” crops have a different impact on the natural resource base and environmental quality from earlier cr...
متن کاملThe development of land quality indicators for soil degradation by water erosion
The paper describes a proposed methodology for estimating water erosion risk for large areas. The estimates are based on a one-dimensional hydrological balance and a physically based sediment transport model. Estimates of risk associated with a given storm amount are integrated over the frequency distribution of daily rainfalls to provide a properly weighted estimate of the average annual risk....
