Identificação de fragilidade ambiental nas estradas Agrovila e Emade Tefé (AM)

Abstract

The processes of formation of environmental fragility captained by roads have proved to be a strong structuring and conditioning factor for activities (social, environmental and economic, among others) in the municipality, as well as for the study of impacts and environmental planning based on land use. The main objective of this work is to analyze the environmental fragility and the use and occupation of the soil in the Agrovila and Emade roads in Tefé (AM). The Agrovila and Emade roads, in Tefé (AM), present the problem of environmental fragility as a constituent element of the relationship between society and nature, this causes various uses of nature as a resource, such uses produce their respective impacts. The approach in this work is from the Geosystems and Socio-spatial Formation as a theory and as basic methods to identify the fragility in these roads from its aspects (natural, social, economic and environmental). The work was also developed based on the relationship between society and nature, as well as with the use of maps, highlighting the dynamising relationship between socio-spatial formation, geosystem, landscape and environmental fragility. The use and occupation of the soil on the roads were identified in classes of use as vegetation, agriculture, pasture, exposed soil and dwellings, being that in the Agrovila road the most intense use was of the fluvial courses for bathhouses occurring the case of the same fluvial course being Used for more than one spa. Several activities have been identified on the roads, such as the intense real estate business that has been intensifying. The environmental fragility of these environments was identified from the Ross methodology (1994), for the fragility of natural environments from the establishment of the society in its specific modalities of use in these environments, we used variables of relief dissection, soil type, use And soil occupation / vegetation cover and rainfall. It was identified two classes of fragility being medium and strong in the two roads and the strong class in the road Agrovila occurs in the initial stretch until approximately the entrance of access to another road studied here. In this area there are villas, pastures, plantations, among other activities and this same area is close to the airport area and also the city dump, as well as one of the river basin that contains use of river courses for seaside resorts. On the Emade road this class was identified in the final section of the road, intense voiceless area and with proximity to the river Solimões. The middle fragility class on the Agrovila road was identified after the dump area and the entrance of the other road to the final stretch of road. In Emade this class was identified from the initial stretch of the road to the vicinity of the final stretch. The use of environmental fragility becomes a fundamental element for the identification, analysis and planning of areas that receive impacts and require protection actions.
