Abstract(s)
The Portuguese agriculture has experienced phases of change and its adaptation to the Common
Agriculture Policy. Although serious problems have subsisted as structural difficulties in spite of the many
public aids, it seems that, slowly, agricultural productivity increased, integrating some technological progress.
However, other expectations related to food auto sufficiency or a more balanced equilibrium in the food trade
were however, not achieved. For that study, after having desegregated possible determinants of growth for the
agricultural sector, the econometric results showed a stationary tendency for all the vegetal production variables;
contrarily, some of the detected growth factors were correlated to animal production, particularly to pork, poultry
and milk production. Beside, the classical econometrics, new methods could allow us to a more in depth analysis
of the state in the Portuguese agricultural activities. Our research uses Geographic Information Systems to those
prompt spatial databases for monitoring land use change. This short essay opens prospects for a much better
understanding of rurality when all those factors contributing to its sustainability, much broader than agricultural
activities will be evaluated under the methods earlier described.
