Analysis of information sources in references of the Wikipedia article "Agriculture in Portugal" in English language version.
In the mid-1980s, agricultural productivity was half that of the levels in Greece and Spain and a quarter of the EC average. The land tenure system was polarized between two extremes: small and fragmented family farms in the north and large collective farms in the south that proved incapable of modernizing. The decollectivization of agriculture, which began in modest form in the late 1970s and accelerated in the late 1980s, promised to increase the efficiency of human and land resources in the south during the 1990s.
