The “Metrópole da Amazônia” Wildlife Refuge Conservation Unit is a large environmental preservation area located in the 11th largest metropolitan region in the country, with an estimated population of over 2 million inhabitants. With immense natural riches, it can be considered the last frontier of urban expansion in the region. The work used landscape geoecology to identify the degree of impact of the geoecological units and the Leopold Matrix, one of the tools used in environmental impact assessment, was used to measure the environmental impacts of the study area. The result was that, within the area of the conservation unit, the two geoecological units described in the study (Tablelands and Plains) are well preserved, but the most impacted was the Tablelands, especially found in the REVIS buffer zone. Finally, proposals were suggested to be analyzed and implemented by the unit's management body in order to mitigate the existing impacts in the study area.

Impactos socioambientais na região da Serra do Piriá, Viseu-PA sob o enfoque da geoecologia das paisagens

Socio-environmental impacts are changes suffered by the environment caused by actions that have a direct influence on the quality of life of populations. These aspects can be seen in the Serra do Piriá region, located in the municipality of Viseu-PA, where among the various activities we highlight mineral exploration that led to sudden changes in the landscapes, with impacts being identified, such as: deforestation, soil destruction, fires , among others. The objective is to analyze the socio-environmental impacts in six communities surrounding the Serra do Piriá, which were directly affected by human activities (mining, livestock farming, animal and plant extractivism) and their consequences related to the communities' appropriation of natural resources. The methodology is based on the assumptions of environmental analysis with a view to Landscape Geoecology to analyze the socio-environmental impacts that will serve as a framework for understanding socio-environmental phenomena. Seven geoecological units were delimited in the study area, and of these, three (UG1) Plateau with Capoeira Vegetation, (UG3) Foothill with Secondary Vegetation and (UG4) Plain Interspersed with Ombrophylous and Capoeira Vegetation presented very critical states, two units (UG5) Hills with Patches of Dense Ombrophyllous Vegetation and Riparian Forest, (UG7) Rivers and Nature Fields presented critical states, one (UG2) Slope with Cavities and Fragments of Primary Vegetation presented an unstable state and finally, one (UG6) Fluviomarinha Plain with Maguezal presented a stable state. The study pointed out that human activities are distorting the landscapes, making it necessary to implement conservation and preservation actions for the landscapes in question.
