Brazil is an agricultural powerhouse and a global frontrunner in several crops, including soybeans, coffee, maize, and sugarcane. However, this position has taken its toll on the country's environmental sustainability over the years, resulting in deforestation, soil acidification, loss of biodiversity, and other environmental hazards. Recently, a new technological paradigm has emerged in Brazil's agriculture, consisting of the intensified use of digital technologies in various production stages. Some of these technologies include artificial intelligence, the Internet of Things, big data, and blockchain, resulting in the so-called Agriculture 4.0. This chapter provides an institutionalist account of Agriculture 4.0 in Brazil, focusing on the challenges and opportunities borne by this new paradigm to the country's environmental governance architecture. Our analysis suggests that Agriculture 4.0 has been adopted slowly but progressively in the country. While some hi-tech portions of the agroindustry have adopted digitalization to improve productivity, they have mostly neglected the possibilities of Agriculture 4.0 to improve sustainability governance. Moreover, except for a few high-capitalized small farmers, digital farming is far from being a reality for the majority of Brazil's family farmers, particularly those located in the North and Northeast regions.
