Environmental degradation due to the misuse of natural resources has drastically changed landscapes in the Amazon. At the same time, discussion, knowledge, and actions on the conservation of forest remnants and restoration of degraded environments have increased worldwide. In this study, we propose to evaluate: (1) to evaluate the process of landscape change over the last 36 years (1984-2020); (2) to identify degraded environments within legally established permanent preservation areas (PPAs); and (3) to map environmental liabilities in degraded rural properties which, according to environmental regulations, must be recovered. The priority areas for restoration were defined considering: a) the environmental liabilities of each rural property; b) the remnant forest in each rural property; c) the rural properties’ boundaries; and d) the degraded PPAs in each rural property. Deforestation followed by land use change in Paragominas municipality increased from 12% (2,336 km2) in 1984 to 45% (8,783 km2) in 2020. Its water network had 20,149 km of rivers and 15,824 springs, and of this total, 4,416 km of rivers and approximately 6,157 springs were in areas under pressure. We identify 638.85 km2 of environmental liabilities, which, must be recovered. When producers protect PPA’s in properties, they conserve soil and water resources as well as contribute to biodiversity maintenance. Despite the consistent reduction over the last few years, forest loss and degradation in the Brazilian Amazon have begun to increase again under President Bolsonaro’s current government. In his statements, he has made it clear that he has no interest in the environment.
