Fig. 6. The knowledge-based approach scheme towards opportunities to policy
development. Policy implementation of specific measures based on incentives and
offsetting schemes may be enforced by a knowledge-based approach. Such an
approach integrates the understanding of the physical constraints effects and the
farm management changes due to the implementation of a measure with
information provided by evidenced-based scenarios. By identifying specific
indicators (e.g. n-potential) and counting on information provided by demonstra-tions and pilot projects, new opportunities for policy development can be created.
