  Information - SSS15 Soil erosion assessment and integrated approaches for remediation (co-listed in HS & GM)

Event Information
On and off-site impacts of soil erosion are increasingly perceived as a major environmental threat by policy makers. At European level this has led to the development of the soil protection policy which recognises soil erosion as the most significant single risk to soil. A number of steps are necessary before such a policy can be effectively managed and implemented. The first step is a distributed assessment of the severity of the phenomenon at a regional scale in order to target and focus the effort on priority areas where erosion risk is most severe. Within these identified areas, more specific, high resolution distributed modelling is then one of several tools in matching individual sites with the most appropriate mitigation or remediation measures.

In parallel with the application of soil erosion processes models, socio-economic aspects also need to be covered to be able to test the efficiency and efficacy of alternative soil conservation schemes with respect to local land management practices and to the social and environmental costs. Land use changes have strong and relevant impacts on soil and water resources availability and vulnerability. Adaptive capacity of these resources is a key factor for political decisions in resources allocation. Problems such as soil erosion, soil salinisation and declining water quality are a by-product of agricultural and urban development, and socio-economic systems tend to support a sectoral management perspective either for soil or water which leads to a lack of integrative approches in developing the requisite land uses policies.

We welcome papers addressing these issues at any appropriate scale, through biophysical or socio-economic modelling, the establishment of tolerable levels of erosion, scenario development, interactions with the CAP, examples of soil conservation policy and practice, and estimates or measurements of on and off-site soil erosion and its costs. In particular we hope to address issues of cross-scale resilience as systems for soil and water management are transformed, with examples of good practice at local to regional scales.
