The production of cashew in Brazil is carried out almost exclusively in the Northeast. The area occupied by cashew trees in Brazil in 2017 was estimated at 505,500 ha; of this total, 99.5% is located in the Northeast. The main producers in this region are Ceará (61.6% of the national area), Rio Grande do Norte and Piauí. However, Brazil, which in 2011 was the fifth largest world producer of cashew nuts, in 2016, fell to 14th position, with 1.5% of the total volume of nuts produced in the world. Vietnam, Nigeria, India and Côte d'Ivoire were the world's largest cashew nut producers in 2016, with 70.6% of global production. In recent years, there has been increased competition with some African countries, where government programs have driven the expansion of culture and processing capacity. It is estimated that at 295 thousand tons per year the installed capacity for processing cashew nuts in the Northeast, however, the Region only managed to produce around a quarter of that quantity. Among the main world producers, Brazil has the lowest productivity. Several factors are pointed out as the cause of the low productivity and the fall in the Brazilian production of cashew nuts. One reason is that most orchards are in a phase of natural decline in production. In addition, the giant cashew trees, which are the majority in the Region, are exploited in an almost extractive manner, with low use of technology.
