Transition to Immigrant Labor

From Checa:
"Until the mid-80´s the labor market was satisfied by a pioneer population, farmers from the Mediterranean mountains... however, in the last decade of the 20th century... the reduced availability of family laborers, together with an increase in the scale of production... created a scarcity of manual labor, also evident in other sectors of the economy. This was alleviated almost entirely through the means of immigrant labor." (82-84)
