Are we going to run out of Brazil nuts? - the amazing superfood under risk from climate change. Extreme seasonal weather conditions, exacerbated by the El Niño phenomenon, are becoming more frequent and occurring at increasingly shorter intervals. These events affect not only the biodiversity associated with the trees but also and primarily - the essential source of livelihood for the Indigenous Peoples and Local Communities (IPLCs) who harvest the nuts. The main harvesting groves are located in preserved rainforest (in the Amazon!) areas and specific indigenous territories - all of which are threatened by deforestation and mining exploration in rare lands. This project began as a pilot in which we sequenced the genomes of all Brazil nut tree specimens in the Kew Herbarium (herbariomics!), as well as those of related species, while simultaneously establishing close partnerships with NGOs and IPLCs. In the long term, we aim to understand the genetic signatures within these species' genomes to identify the individual trees and populations that are most resilient to extreme weather conditions and to the ecosystem as a whole.
