This article aims to show how the Lula government can make the agricultural sector sustainable in Brazil. In the 20th century, in the 1960s and 1970s, significant increases in agricultural production and productivity were achieved thanks to the green revolution implemented in the country, which brought numerous problems to the environment. The Green Revolution in Brazil was a phenomenon marked by the large-scale use of technology in rural areas. The indiscriminate use of pesticides has led to contamination of water and soil and has had drastic effects on non-target species, affecting biodiversity, food webs and aquatic and terrestrial ecosystems. Unlike large properties, where monoculture is generally concentrated, family farming produces a greater diversity of crops, which generates a positive impact on product quality. Unlike the green revolution characteristic of large properties, soil management is usually organic, with respect for the ecosystem, reducing the impact on the environment. When considering food consumed in the country, 70% comes from family farming, according to IBGE data. For these reasons, it is fundamental to rethink the model of technological development that has been adopted for agriculture in Brazil. The environmental sustainability of Brazilian agriculture and livestock needs to be developed on an ecological basis. Sustainable agriculture requires crop rotation, use of natural fertilizers and biological insecticides so that these practices contribute to a healthier soil that is capable of meeting production needs without compromising future generations. 1.2% of landowners own 45% of the land used in agricultural activities in Brazil. Sustainability for the agricultural sector will not be achieved only by overcoming environmental problems, those of production and productivity with the abandonment of the model based on the green revolution and the adoption of a new model to be developed on ecological bases, but also, with the effective reduction of the excessive concentration of land ownership in the hands of a few, through an agrarian reform to the most democratic possible.
