The article explains the implementation of a subsidy program in Brazil, specifically for the açaí market in Curralinho, aimed at protecting local producers from financial losses when their products are sold at prices below the government's minimum. This initiative, known as PGPM-Bio, requires producers to register their sales, provide necessary documentation, and meet certain registrations to be eligible for the subsidy. The subsidy not only helps maintain a minimum price for açaí but also promotes environmental conservation and the preservation of traditional cultures. The program is part of a broader effort to improve the income and working conditions of local residents, with Curralinho's Human Development Index serving as a key indicator of progress.
