What is our response ?

EC:
“Towards a strategy for soil protection”

LAWINE
LAWINE:
We want to develop an integrated assessment approach to understand, monitor and predict
the impact of wind erosion and tillage practises on land degradation

Integrated assessment:
A reflective and iterative participatory process that links knowledge (science) and actions (policy) regarding complex issues

Integrated assessment:
A reflective and iterative participatory process that links knowledge (science) and actions (policy) regarding complex issues
Interdisciplinary process of combining, interpreting and communicating knowledge from diverse scientific disciplines in such a way that the whole cause-effect chain of a problem can be evaluated from a synoptic perspective

Integrated assessment:
combine existing scientific and multi- disciplinary excellence

LAWINE
Objectives:
understand monitor predict
the impact of soil particle emissions on land degradation and vulnerability of managed,
semi-natural and natural ecosystems in Europe, in the context of
• land use• climate change
24
LAWINE
Expected results:
Products (risk maps, scenario maps, assessments)
Services (on-line prediction, model system for scenario calculations)
New knowledge on wind-soil interactions and its response to global change and changes in human activities
Policy support
