In Paraná, Brazil, the price of cassava reached an all-time high in 2021 due to a combination of factors including reduced area, decreased productivity, and increased exports. The high price of soybeans made cassava more profitable for farmers. Factors contributing to the price increase include a decrease in planting area, climate issues, and a labor shortage. Cassava is important for both direct consumption and industrial use, with Paraná hosting the largest industrial park in the country, accounting for 70% of Brazil's starch production. Despite the high prices, producers face uncertainty due to fluctuating starch content in the roots. International demand for cassava is also contributing to the price increase.
