Coffee powers Vietnam's economy, and its production in small plots may have pulled millions out of poverty, according to this report from BBCNews.
"How did its market share jump from 0.1% to 20% in just 30 years, and how has this rapid change affected the country?
Coffee production…" grew by 20%-30% every year in the 1990s. The industry now employs about 2.6 million people, with beans grown on half a million smallholdings of two to three acres each.
This has helped transform the Vietnamese economy. In 1994 some 60% of Vietnamese lived under the poverty line, now less than 10% do."
