Conflict Analysis of Land Use and Land Cover in the Permanent Preservation Areas of Ifes - Alegre Campus, Espírito Santo State, Brazil

ABSTRACTThis study aimed to analyze the conflict of land use and land cover in Permanent Preservation Areas (PPA) of the ‘Instituto Federal de Educação, Ciência e Tecnologia do Espírito Santo’ - Ifes, Alegre Campus, in light of the current Brazilian Forest Code. The springs, watercourses, slopes and hill tops of the PPA were defined and investigated. The slopes and hill tops were obtained by the global digital elevation model GEDM-ASTER. Land use and land cover were achieved by photo-interpretation of orbital image sensor Geoeye 1 (spatial resolution of 0.50 m), totaling 36 thematic classes. The results showed that the PPAs occupy 34.33% of the total Ifes area, with an extension of 114.32 ha. The hilltops and watercourses occupy the largest areas, corresponding to 16.94% and 14.03%, respectively. The watercourses are the most affected areas, and the main classes responsible for conflicts are natural pastures (20.41 ha) and non-paved roads (1.18 ha).
