Robusta coffee is making a comeback in Africa, years after its production plummeted in the 1990s and early 2000s due to a fall in its price on the global market as civil war, pests and diseases affected some producing countries on the continent.

Production of Robusta coffee variety currently accounts for about 40 percent of Africa’s total annual production, an increase of about 10 percent from three years ago.

Prices have been on the rise in countries like Uganda – the highest Robusta coffee producer in Africa — since May 2016 when a kilogramme went for $75.60, according to Business Week.

Robusta coffee prices have increased by 5.8 percent globally so far this year, after years of lagging behind Arabica coffee, the world’s most popular bean variety.

“This season, I have earned more money than I always earn from around two harvests. Prices are better and we have harvested more coffee beans,” Imelda Muwonge, head a coffee farmers group in Central Uganda, told Wall Street Journal.

The East African country – the second coffee producer on the continent after Ethiopia –registered a record 4.8 million bags in the 2015-16 season, a far cry from early 2001, when more than 50 percent of the nation’s crop had been wiped out.

Ivory Coast, the second biggest Robusta coffee producer in Africa, recorded 2.2 million bags, which was the nation’s highest harvest in six years.

The West African nation, alongside South Sudan and Congo had seen their robusta coffee crops wither on the farms as civil wars took a toll on agriculture in previous years.

South Sudan reportedly shipped its first volumes of coffee production in October last year, marking it the first non-oil exports to come out of the country in over a generation, Sudan Tribune reported.

The young African nation is the most oil-dependent country in the world, with oil accounting for almost the totality of exports, and around 60 percent of its gross domestic product.

Farmers across the continent have adopted better farming practices which boosted production on the continent’s rainfall-dependent farm economy.

“More farmers are embracing modern farming technologies. This is making a huge difference,” Rick Peyser, a coffee expert with Lutheran World Relief, a charity working to improve the crop’s production in Africa, told Wall Street Journal.

The improving fortunes of robusta coffee farmers in Africa come at a time when farmers in Brazil, Colombia and Vietnam are experiencing a slump due to droughts.

Vietnam is the world’s leading producer of robusta coffee.

Africa contributed a record 12.91 tons to the global production in the 2015-16 season.

The improved fortunes represent a turnaround for African growers, whose coffee production has dwindled since 1970s, when the commodity accounted for about 30 percent to the global output.
