Thanh now harvests about 4.5 to 5 metric tons a year on his 1.5 hectare (3.7 acre) plot in the Central Highlands. He sells the pepper for about 190,000 dong ($8.90) a kilogram, or more than nine times his production costs, he said by phone November 14.
International trade
Vietnam's agricultural industry was boosted by the "Doi Moi" reforms of the 1980s, which opened up international trade to farmers. They responded by planting more pepper, coffee and rice. The Asian nation produced 1.3 million tons of coffee in 2012, an 11-fold gain in two decades and second only to Brazil, according to the Rome-based FAO.
Through the centuries, India and Indonesia's Sumatra were the biggest pepper suppliers, said Marjorie Shaffer, author of Pepper: A History of the World's Most Influential Spice. While pepper is a traditional crop in Vietnam, it only emerged as a major producer recently, said Shaffer, a science editor at the NYU School of Medicine Office of Communications.
"Before the 1990s, we didn't even produce enough pepper for domestic use," Do Ha Nam, chairman of the Vietnam Pepper Association, said from Ho Chi Minh City on November 11. "Then output increased unbelievably after we opened up the economy."
122,000 tons
Vietnam harvested 122,000 tons last year, while Indonesia produced 63,000 tons and India 58,000 tons, according to IPC data. Global output was 375,800 tons in 2013, little changed from a decade earlier, even as exports surged 23 per cent to 278,033 tons, IPC data show.
Rising pepper prices helped farmers prosper and allowed them to buy cars and bigger houses, Nam said. Almost half of Vietnam's labour force is employed in agriculture and the sector accounts for about a fifth of the economy, according to data in the CIA World Factbook.
Pepper is cultivated on vines, which grow best in tropical climates from 460 metres above sea level, according to the IPC. Vietnam's harvest runs from February to April, according to the FAO, which says pepper and ginger are the oldest traded spices. While the first exports were recorded 4,000 years ago, trade took off from the 1400s after Europeans pioneered maritime trading links with Asia.
Export focus
The ratio of global pepper stockpiles to consumption now stands at less than 10 per cent, from as much as 75 per cent in 2004, according to Olam, which grinds pepper at plants in Ho Chi Minh City for export.
"Vietnam becomes more and more important because it focuses on exports and does not have a rapidly expanding market for domestic consumption," Estep said from Fresno, California. The country "has done a very good job of maintaining yields, maintaining productivity," he said.
Growers have small farms in Vietnam, often 1 to 2 hectares, according to the IPC. Output averages 2.2 tons per hectare, compared with 400 to 500 kilograms in Indonesia.
Vietnam's output should hold steady at 130,000 tons to 135,000 tons next year, said Nam of the Vietnam Pepper Association. Prices will also be similar, at $7,000 to $8,000 a ton, he said. That should be enough for Thanh, the Dak Lak farmer who's planning to expand.
"I could buy a car if I liked," he said. "But I want to buy more land to expand production first."
