Plantation farming involves the growing and processing of single cash crop for export to temperature lands. The plantation is organized on an efficient basis. The land is devoted to single crop and the entire production is exported to temperate land. During the time of colonization, the European introduced plantation agriculture in the equatorial regions. Areas of plantation farming, for the most part, lie near the sea because of ocean transport.
