In terms of agricultural productivity and income, since Spain's incorporation into the European Union (EU) the primary sector of the regional economy has evolved dynamically. Among the reasons for this are growth rates higher than the national average, as well as increased capitalization fostering specialization and modernization, including the integration an externalization of the sector, whereby activities previously performed on the farm are now performed elsewhere. These changes have been fostered by the regional articulation of the EU's Common Agricultural Policy. Since 1986, subsidies have played a significant role in this sector.
