ARAÇUAÍ & BELÉM, Brazil — When Aécio Luiz was younger, finding wild beehives was routine in his rural Afro-Brazilian community of Córrego Narciso. A farmer turned beekeeper, he recalls their buzzing was easy to spot when he worked around his property in Brazil’s Jequitinhonha Valley. “Now, that has become a rarity,” he tells Mongabay. Although Luiz and other locals are uncertain of the cause, they started to notice changes in various bee species’ behavior around 2021, when Sigma Lithium, a Canadian company producing lithium used in electric vehicles, began building a plant in the region. It was the latest in a wave of economic activity, including the arrival of other lithium projects and eucalyptus plantations, altering the valley’s landscape. “In the past four years or so, we basically stopped coming across wild [native] bees and their nests,” says resident Osmar Aranã, of the Aranã Indigenous people. “Before then, you’d see them flying around all over the place.” Researchers say the issue raises questions about the impacts of critical mineral mining on bee species and how this interacts with global climate goals. Lithium, for example, powers renewable technologies to mitigate climate change, which bees can be vulnerable to. “Any small alterations to the microclimate of such a vulnerable region could spark a domino effect on vegetation, biodiversity — and on bees,” says André Rech, a professor at the Federal University of the Jequitinhonha and Mucuri Valleys and an expert in pollination ecology. But lack of sufficient studies and regulation on the…This article was originally published on Mongabay
