Análise geoecológica como subsídio ao planejamento ambiental da sub-bacia hidrográfica do igarapé ambé, Altamira-PA

Although the Amazon Biome has an incalculable value for the balance and maintenance of life on the planet, in recent years it has suffered from the construction of controversial infrastructure works, in particular the opening of highways and construction of hydroelectric plants, such as the BR-230 Highway (Transamazônica) and the Belo Monte Hydroelectric Power Plant, as happened in the Xingu River hydrographic basin, which caused and can still entail several modifications at different spatial scales, mainly at the local level. Therefore, it is extremely important to understand the functioning of these landscapes and their tendencies towards changes arising from human activities, thus providing subsidies to plan environmentally sustainable uses. Adopting the concept of hydrographic basins as a physical-territorial unit for measuring socio-environmental impacts and the geoecology of landscapes as a methodology for systemic environmental analysis, this research aims to study the operation and changes caused by the opening of the Transamazon Highway and its construction of the Belo Monte Hydroelectric Complex in the Igarapé Ambé hydrographic sub-basin which has its territorial extension cut by the aforementioned highway and is located within the Direct Influence Area (AID) and the Directly Affected Area (ADA) of the Belo Monte Hydroelectric Complex and that drain the urban area of the city of Altamira in the State of Pará. The analyzes show that 45% of the SBHA's landscapes are with active morphogenetic processes and 29% are with moderate environmental vulnerability and in a fragile stage of ecodynamic balance, which shows the importance of thinking about alternative uses for these landscapes.

Percepção ambiental e dinâmica geoecológica: premissas para o planejamento e gestão ambiental

It is necessary to plan the actions of humans in nature, organizing sustainable interventions within environmental limits, and manage natural resources through comparisons with other landscapes already changed. But, part of the actions of environmental planning and management occur through sectoral analyzes, and without understanding how the local population perceives the nature. In this article we discuss about the geoecological landscape analysis and its relationship with the complex thinking and the importance of environmental education as a means of dissemination of geoecological knowledge of the landscape. It proposes fundamental elements for environmental planning and management of natural resources, through considerations about the need for knowledge of the environmental perception of social actors on their actions on the natural environment, and the impact of these actions on the local geoecological dynamics. The land use contribute significantly to changes in local environmental dynamics. Thus, the understanding of the geoecological dynamics, such as environmental perception of local communities, should be seen as premises for development of environmental planning and management
