Tridge summary

A study conducted by the Federal University of Lavras (UFLA) and other institutions found that the El Niño phenomenon caused a significant decrease in the production of Amazon nuts in 2017. The drop in production was attributed to reduced local rainfall and increased temperatures in the Pacific Ocean, caused by the El Niño event in 2015/2016. The researchers suggest that further studies should be conducted to explore methods to reduce the impact of climate events on nut production, such as genetic improvement of Brazil nut trees.

El Niño involves atmospheric and oceanic factors and originates in the territory of Peru, resulting in climate change. A survey with the participation of the Federal University of Lavras (UFLA), in partnership with other national institutions, revealed that this phenomenon contributes to the drop in the production of Amazon nuts, also known as Brazil nuts. The researchers reveal that the search for this relationship came from the fact that, after the occurrence of one of the most intense El Niño episodes in late 2015 and early 2016, there was a sudden drop in the production of this nut in the following year (2017). . Data from the Brazilian Agricultural Research Corporation (Embrapa) in Amapá, which has been monitoring the fruits of this species since 2007, revealed that never before had such a large reduction in the production of Amazonian nuts been seen. The results of the study show that this drastic drop in production in 2017 is directly related to the reduction in local ...
