SUMMARY:

The Amazon has been undergoing constant processes of use, occupation, deforestation and changes in land use and coverage between 1960 and 2022. This process is associated with territorial policies, which are still in place today (2025). These policies are linked to government programs for the implementation of infrastructure, colonization projects, agricultural/agro-mineral projects and, more recently, in an expanded manner, to the installation of hydroelectric plants and waterways, among many others. All these expressions of territorial policies mobilize the advance and displacement of the frontier (understood in this work as the relationship between the displacement of multiple capitalist relations of production in geographic space) over the period from 1960 to 2022. Thus, the Legal Amazon is the spatial focus of the research, and the temporal focus encompasses the years from 1960 to 2022. The thesis defended is that the mobility of the frontier in the Amazon has continuous but intensified temporalities and spatialities, with the temporal-spatialities of settlement and agriculture, as well as the consolidation of settlement and the agro-mining-energy infrastructure (infrastructure, agriculture, mining and energy), being the three most important macro-dimensions of territorial use, shaping the expansion, displacement and mobility of deforestation in the Legal Amazon. To analyze the mobility of the border and its temporal-spatiality in the Legal Amazon, in order to understand how territorial macro-policies materialize in deforestation in the Amazon, seeking to understand how the territorial macro-policies of migratory actions, infrastructure, agriculture and mining; occupational consolidation and socio-environmental actions, and to put an end to the territorial infra/mineral/agro/energy articulation have repercussions on deforestation in the Legal Amazon. To understand the mobility of the border and its temporal-spatiality in the Legal Amazon, the theoretical and analytical foundation developed in the research work is based on geographic science, whose approach has the territory as a category of analysis, added to the conceptual discussions of multidimensionality of the use of territory, territorial policies and advance/displacement of the border. The research methodology was composed of three operational phases, the first concerns the understanding and discussion of the theory and concepts carried out within the scope of the research work. The second phase is associated with data collection and documentary research used to understand the displacement of the frontier, its spatialities and uses of the territory in the Amazon. Finally, the last phase involves the systematization and analysis of the data in light of geographic theory, demonstrating cartographically the temporal-spatiality of the frontier and its repercussions on the advance of deforestation in the legal Amazon. The displacement of the frontier in the Amazon, analyzed in the work in three continuous periods, left a large extension of deforestation in the Amazon materialized, cartographically verified between 1986 and 2020, also marked by a growing replacement of forests in areas under agricultural, urban, mineral and other land uses. In the current period (2022), there is a demographic and economic occupation of the Amazon, beyond the so-called “deforestation arc” or “population arc”, expanding into other regions of the Amazon, in many cases conflicting with land use planning, such as Conservation Units and Indigenous Territories. The displacement of the frontier in the Amazon has resulted in a large extension of deforestation, and of course a large replacement of forest areas with areas for agricultural, urban, mineral and other land uses, which have been converted by various territorial policies, manifested in the displacement of the frontier, characterizing a demographic and economic occupation of the frontier beyond the deforestation arc or even the settlement arc.
