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

Abstract

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.
