In the Xingu Integration region, the dynamics of land use and land cover takes place through accelerated transformations, consolidated mainly by road transport networks, especially from the 1970s onwards with the opening of the Transamazon Highway (BR-230). Thus, the work prioritized analyzing the dynamics of land use and land cover in the municipality of Senador José Porfírio, located in an area of intense socioeconomic and environmental change, especially after the installation of the Belo Monte Hydroelectric Power Plant. In this sense, the methodological procedures focused on collecting information and data in digital databases, and on the subsequent analysis and interpretation of the material obtained and bibliographical research on the dynamics of land uses in the Amazon region and on the use of geotechnologies as tools for monitor the territorial dynamics of these uses. Thus, in the first stage of the work, bibliographical research was carried out in digital databases, seeking studies on the dynamics of land uses in the Amazon region and on the use of geotechnologies as tools to monitor the territorial dynamics of these uses, particularly in relation to the process. deforestation, one of the most sensitive issues in the environmental issue today. In the second stage of the work, the website of the Annual Mapping Project for Land Cover and Land Use in Brazil - Mapbiomas, Brazilian Institute of Geography and Statistics (IBGE) and Instituto Socioambiental (ISA) were searched for land use and occupation of the municipality of Senador José Porfírio for the period 2010 to 2018. The same is being done in PRODES 2019 (General Coordination of Earth Observation-OBT/INPE). The objective of the research was to analyze the dynamics of land use in the municipality of Senador José Porfírio, from 2010 to 2020, considering the historical and economic aspects, as well as their socio-environmental, landscape and territorial expressions. In the results, it was found that, for this period of research, agriculture suffered variations in its perennial culture in relation mainly to government restrictions, but there was an emphasis on cocoa production. It was analyzed that illegal logging, deforestation, in addition to land grabbing for agricultural production has been advancing mainly in areas of settlements and indigenous lands, which intensified political, socio- environmental, economic, land and landscape problems, especially with the sector agriculture, mining, traditional peoples and agroextractivos. In this context, there is an accelerated process of antagonistic appropriation of space by its various social agents for eventual productions of territories and territorialities. In this regard, in this 21st century, with the entry of international capital in the municipality of Senador José Porfírio-PA, local populations and their ways of life are still disregarded.

Dinâmicas territoriais no município de Salinópolis/PA: unidades espaciais, ações públicas e a conservação ambiental

Coastal spaces focus special attention with regard to ecological, political and social discussions contemporary because they are areas increasingly densely populated, encompass essential ecological functions and have huge economic importance. The production of space on the Amazon coast points to a diversified reproduction movement, causing problems related to the natural, social and economic dynamics, what resonates in contradictions that are revealed in the fragility of the public actions in the coastal municipalities. The Municipality of Salinópolis concentrates a diversity of socio-spatial practices marked by the complexity of the activities established in its spatial reproduction process. This study focuses on the territorial dynamics in the municipality of Salinópolis from the forms of use throughout the space production process. Analyzes that the use today generates social and environmental inconsistencies, with significant loss of its natural and landscape resources, which reveals that coastal policies are often economistic, giving priority to certain activities such as tourism and the urbanization. Several public actions are taking place in the municipality to manage productive activities. These actions can cause conflicts due to the discrepancy of land use that does not show concordance with social dynamics and environmental conservation.
