Abstract(s)
This paper discusses research aiming at assessing Common Agricultural Policy impacts on agriculture and
forestry. For this purpose an approach is developed that includes a linear programming model to estimate
the Positive Mathematical Programming production cost function coefficients of current agricultural–
forestry activities. It further includes a heuristic — simulated annealing — to generate solutions for each
policy scenario. This model base approach is integrated within a decision support system (DSS) for testing
purposes. The DSS further encompasses a relational database that stores agricultural–forestry technical and
economic data and a geographic information system that stores topological data of regional farm-type land
units. The DSS Graphical User Interface provides tabular and geographical reporting capabilities. Results are
discussed for an application to the Alentejo region in Southern Portugal. Results demonstrate the usefulness
and relevance of the proposed approach to assess the impact of changes in prices and in agricultural policy
on land use patterns and on forestry
