‘Acai-ification’ of the Amazon

Long eaten by Indigenous groups, acai is a culinary mainstay in northeastern Brazil, eaten with manioc flour or used to accompany fish and other dishes.

Its deep-purple pulp shot to popularity across Brazil over the past two decades, often drunk as juice or made into a sweetened sorbet and served with fruit and granola.

From there, acai went on to win fans worldwide, from the United States to Europe, Australia and Japan, where it can sell from around $5 per bowl to upwards of $20 for a 100-gram packet of organic acai powder.

Brazilian exports of acai and its derivatives surged from 60kg in 1999 to more than 15,000 tonnes in 2021.

Para, the source of 90 percent of Brazil’s acai, produced almost 1.4 million tonnes of it in 2021, worth more than $1bn for the state’s economy.

But studies show the expansion of acai palms in the Amazon is causing a loss of biodiversity in some regions by replacing other species.

“Leave nature to its own devices, and you get 50 or maybe 100 acai plants per hectare,” says biologist Madson Freitas of the Museu Goeldi research institute in Belem.

“When you go beyond 200, you lose 60 percent of the diversity of other native species.”

He has published a study on the phenomenon, which he calls “acai-ification”.

The loss of other plant species in turn has a negative effect on acai, which becomes less productive because of a loss of pollinators such as bees, ants and wasps, he says.

Longer dry periods in the Amazon, which may be exacerbated by climate change, are also hurting acai, which tends to grow on land that floods during the rainy season.

‘Environmental service’

Freitas, like Diogo, comes from a “quilombo”, communities founded by runaway slaves in Brazil in the 17th and 18th centuries.

He says stronger conservation laws and policing are needed to combat single-crop farming, as well as incentives for farmers to preserve the rainforest.

Salomao Santos, a local leader in Igarape Sao Joao, admits acai’s dominance could become a problem.

“Those of us who live in the Amazon know we can’t live on one single species,” he says.

He recalls the commodity booms and busts of the past, such as sugarcane and rubber.

He wants compensation for quilombo residents and others who preserve the Amazon, whose hundreds of billions of carbon-absorbing trees are a vital resource against climate change.

“We provide a huge environmental service to the world,” he says.
