Abstract

XAVIER, António  and  ROSARIO, Maria do Socorro. An analysis of the recent dynamics of the standard output of crops in the municipalities of mainland Portugal. Rev. de Ciências Agrárias [online]. 2023, vol.46, n.3, pp.1-10.  Epub May 04, 2023. ISSN 0871-018X.  https://doi.org/10.19084/rca.31500.

The Common Agricultural Policy (CAP) had consequences and influenced different cultural choices. The analysis of this policy must have a sufficient level of disaggregation to allow a local analysis, especially when considering the various temporary and permanent crops. In this sense, the recently published 2019 Agricultural Census provided information disaggregated at these levels. However, the current information on the total standard output (SO) by municipality does not spatialize the standard output coefficients (SOC) of the different temporary and permanent crops, nor the contribution to the municipality's SO of these cultures. On the other hand, it is necessary to create typologies of municipalities to identify similar dynamics and specific trends of the SOC of temporary and permanent crops, which may imply policy measures directed at the local level. The present study aims to address these information gaps. All municipalities in Portugal were considered as a case study and data from the 2019 Agricultural Census was used. In a first step, the standard output (SOC) were calculated for the different types of temporary and permanent crops; then in a second step, an HJ-Biplot and cluster analysis was applied and typologies of municipalities were identified with regard to their cultural orientation; in a third step, the total SOs of temporary and permanent crops were calculated, the contribution of each municipality to the region and mainland Portugal, as well as the SOC per hectare of temporary and permanent crops; finally, a spatial analysis of the results was made using geographic information systems. The results of the implemented approach made it possible to have a new vision of the territory in terms of agricultural crops, providing relevant information for the analysis of agricultural policies.
