Atiu Island. Cook Island. Polynesia. South Pacific Ocean. One of the growers teaches coffee beans grown on the island of Polynesia.  Atiu has a long history of growing coffee. Missionaries established it commercially in the early 19th century. By 1865, annual exports of coffee from the Cook Islands amounted to 30,000 pounds. The islands' ariki (high chiefs) controlled the land used for planting and received most of the returns. The commoners often saw little if any reward for their labour. In the late 1890s, Rarotongan coffee production suffered due to a blight that affected the plants. Coffee production declined and had to rely more on crops from the outer islands Atiu, Mauke and Mangaia. World Wars I and II resulted in a further export reduction and eventual standstill. In the 1950s the co-operative movement in the Cook Islands resulted in the re-establishment of coffee as a cash crop. On Atiu, under the supervision of New Zealand Resident Agent Ron Thorby and the Cook Islands Agriculture Department, new coffee plantations were established. The raw coffee was destined for export to New Zealand where it was processed and marketed. By 1983, the coffee industry had collapsed. Government stepped back and left the plantations to their landowners. The poor financial return from selling their coffee to a Rarotongan company for processing had prompted the farmers to stop production except for their own private use. The plantations were overgrown with creepers. Commercial coffee production was revived sometime in 1984, with the founding of Atiu Coffee Factory Ltd. by German economist Juergen Manske-Eimke. As of 2012, the Atiu Coffee Factory managed 39 hectares of land and produced 4.5 tonnes of roasted beans.
