SPATIAL AND TEMPORAL ANALYSIS OF THE STATE OF CONSERVATION OF LAGOAS E DUNAS DO ABAETÉ ENVIRONMENTAL PRESERVATION AREA

Spatial and temporal analysis of the state of conservation of the Lagoas e Dunas do Abaeté Environmental Proctetion Area

Abstract

An Environmental Protection Area (APA) has the main objectives of protecting biological diversity, disciplining the occupation process and ensuring the sustainability use of natural resources. The APA das Lagoas e Dunas do Abaeté is the last urban sources of the ecosystem of dunes, lagoons and restinga still conserved in the city of Salvador, Bahia. Although legally protected, the APA is loosing its single characteristics due to the intensifying process of urban occupation and real estate speculation along the coastal area, leading to the progressive degradation of its physical, chemical and biological components. The present work had as general objective to map and characterize biophysical environmental aspects and environmental conflicts existing in the APA Lagoas and Dunas do Abaeté, using the application of geotechnologies. From the space-time analysis, between 1976 and 2017, it was possible to observe a growth of urban areas within the APA of 1.161%, while in this same period the class of the lagoons were reduced by 14%, the dunes reduced by 21 % and vegetation reduced by 35%. The interval of greatest urban expansion was from 1976 to 1989, driven by the implantation of the Petrochemical Complex of Camaçari.
