This paper discusses the development and application of a spatial tool for erosion modeling named Spatial Decision Assistance of Watershed Sedimentation (SDAS). SDAS computes export (yield) of sediment from watershed as product of erosion rate and sediment delivery ratio (SDR). The erosion rate is calculated for each raster grid according to a digital elevation model, soil, rain fall depth, and...

Climate change affects agriculture differently due to the heterogeneity in bio-physical and economic conditions in Austria. Therefore, stakeholder and expert knowledge is required in regional vulnerability assessments to address region specific challenges and develop compatible adaptation strategies. In a transdisciplinary research project, a working group consisting of regional stakeholders an...

Land abandonment is among the most complex la nd use change processes driven by a multiplicity of anthropogenic and natural factors, such as agricultural over-exploitation, implementation policies, socio-economic climatic aspects. Therefore, it necessary to deepen effects land based on methodologies that are multidisciplinary possible. Environmental social problems related include soil erosion ...

Abstract Functions and services provided by soils play an important role for numerous sustainable development goals involving mainly food supply environmental health. In many regions of the Earth, water erosion is a major threat to soil functions mostly related land-use change or poor agricultural management. Selecting proper management practices requires site-specific indicators such as erosio...

Soils are the third largest global reservoir of carbon and the largest terrestrial ecosystem sink or source of atmospheric CO2 depending on land-use and management. The French authorities ahead of COP21 proposed the ‘four per mil’ initiative aimed at offsetting most global agricultural CO2 emissions by increasing global soil organic carbon (SOC). Since, the Common Agricultural Policies (CAP) re...

Soil erosion is an important environmental problem that can have various negative consequences, such as land degradation, which affects sustainable development and agricultural production, especially in developing countries like Tunisia. Moreover, soil a major around the world because of its effects on fertility by nutriment loss siltation water bodies. Apart from this, most serious type severa...

This study has evaluated the runoff and erosion rates in torrents of Southern Italy, two forested headwaters with very similar climatic, hydrological geomorphological characteristics; one headwater, 15 check dams were installed mid-1950s, while other is not regulated engineering works. To this aim, variables have been modeled over years after dam installation using HEC-HMS (Hydrologic Engineeri...

The land problem that commonly occurs in Ranu Pani Watershed is erosion. an area located the mountains with very high soil Therefore, it necessary to conduct good management upstream and downstream areas. first step before carrying out analyze occurrence of erosion Watershed. purpose this research was predict potential distribution spatial data.. results showed erosivity value 961.44 heavy clas...

In the Czech Republic, Universal Soil Loss Equation provides basis for defining soil protection strategy. Field rainfall simulators were used to define actual cover-management factor values of most extensively seeded crops in Republic. The second purpose was assess rainfall-runoff ratio different and management contribute debate water retention effectiveness during approaching climate change. m...
