Agriculture in Portugal is based on small to medium-sized family-owned dispersed units; however, the sector also includes larger-scale intensive farming export-oriented agrobusinesses backed by companies (like Grupo RAR's Vitacress, Sovena, Lactogal, Vale da Rosa, Companhia das Lezírias and Valouro). The extent of cooperative organisation has been reaching a greater importance with globalization. Portugal produces a wide variety of products, including green vegetables, rice, corn, wheat, barley, olives, oilseeds, nuts, cherries, bilberry, table grapes and edible mushrooms. Forestry has also played an important economic role among the rural communities and industry (namely the paper industry that includes Portucel Soporcel Group, the engineered wood industry that includes Sonae Indústria, and the furniture industry that includes several manufacturing plants in and around Paços de Ferreira, the core of Portugal's major industrial operations of IKEA). In 2013, the gross agricultural product accounted for 2.4% of the GDP. Portugal is the largest world producer of both cork and carob, as well as the third largest exporter of chestnut and the third largest European producer of pulp. Portugal is among the top ten largest olive oil producers in the world and is the fourth biggest exporter. The country is also one of the world's largest exporters of wine, being reputed for its fine wines. The land area of slightly more than 9.2 million hectares was classified as follows (in thousands of hectares): 2,755 arable land and permanent crops (including 710 in permanent crops), 530 permanent pasture, 3,640 forest and woodland, and 2,270 other land.
Agriculture, forestry, and fishing employed 17.8 percent of Portugal's labour force but accounted for only 6.2 percent of GDP in 1990. With the principal exception of the alluvial soils of the Tagus River valley and the irrigated sections of the Alentejo, crop yields and animal productivity remained well below those of the other European Community (EC) members.
