Forests provide vital food resources, especially for human populations. However, global human-induced changes pose a significant threat to food security worldwide. The biodiverse Brazilian Amazonia is home to 19 million people, many of whom depend on plants for sustenance. Here, we analyse the effects of future projected global human-induced changes, including deforestation and climate change, on edible plants in the Brazilian Amazonia. We used species distribution modelling based on the MaxEnt algorithm to estimate environmental suitability and the effects of future human-induced changes on human populations in the region by 2050 at the municipal level. We identified 228 edible species with valid distribution models. These species exhibited a broad distribution, covering an average of 60 % of the forest area. Most species are expected to show reduced environmental suitability by 2050, contributing to a decrease in species estimated richness, particularly in the eastern, southern, and central parts of the Forest. Impacts were high in municipalities with smaller forested areas. We identified 21 edible species that are potentially resilient to human-induced changes, most of which provide edible fruits and seeds. According to our projected scenarios, most edible species are likely to be affected by human-induced changes. Exploring resilient edible plant species is crucial for food security and supporting forest-dependent populations.
