Territórios da conservação: uma análise do potencial fitogeográfico das UC's de uso sustentável em Sergipe

Abstract

This thesis is empirical cut CUs of Sustainable Use of Sergipe, and to objective analyze the potential and importance in the State of Sergipe phytogeographic leaving the CUs of Sustainable Use. The development of this thesis was outlined from the methodological procedures: a) bibliographical and documentary; b) field research, a survey of secondary and primary data from semi-structured interviews; informal dialogues with various social actors; and systematic observations in the territories surveyed; c) preparation of mosaics and landscape metrics from remote sensing, using the scale ortofotocartas/2003 1:10,000 and 1:2000, whose images were treated in ArcGis 9.3 and Patch Analyst tool for calculation of landscape metrics d) planning and tabulation of data obtained; and e) analyzing and interpreting information. The CUs surveyed are endowed with potential phytogeographical, represented by enclaves of dense rain forest, mangrove vegetation, secondary vegetation, restinga, dunes fields and floodplains. This potential has been affected by the various uses assigned to the territories surveyed: cultivation, pasture, azing, aquaculture, industry, mining extraction, over dery activity to tourism which is growing in the south coast. These uses have led to unplanned territorial conflicts, resulting in the exclusion and/or dispossession of traditional communities and small local producers resulting in losses to the biosociodiversidade. The landscape metrics showed that a significant portion of the fragments are surrounded by the edge effect, which means the Core Area showed that 43,17% of the area of fragments of the South Coast APA, and 52,35% Flonai and the surroundings are less prone to edge effects (relative interior-edge stain). The Mediun of the Index of Form (MSI) indicated that the fragments have irregular forms 1,59 and 1,45 respectively, where the format is far from the circular pattern. The Proximity Index higher distances between the identified fragments characterizing the isolation of stain. These index are the result of the uses assigned to the territory and failures in the management of CUs through environmental agencies as even created in the 1990, still has no mechanism for environmental management can deter harmful actions, contradicting the rules established by the policy of environmental conservation. The maintenance of biophysical attributes, depends on the creation and implementation of mechanisms for environmental management, linked to actions for the connectivity of forest remnants, which can become part of future corridors of atlantic forest. The management plan should include the traditional concerns of the communities that depend on these resources. Thus, proposals that encourage the use of "standing forest" through non-timber activities should be prioritized. Thus, it is essential that the managing agency know the reality of CUs end search alternative paths from the perspective of overcoming the challenges in environmental management, and can contribute effectively to the development of inclusive public policies in the light biosociodiversidade.
