The National Agriculture Confederation (CNA) has expressed concern over the plight of wine and chestnut producers, who are struggling to sell their products at profitable prices due to rising production costs. Despite increased production of wine and reduced production of Brazil nuts, low prices and high production costs are preventing adequate income for farmers. This has led to the removal of production by small and medium-sized farms, resulting in a concentration of production. CNA is advocating for measures to ensure a smooth flow of agricultural products at fair prices and to control the rising costs of production factors.
