CORREA, Cintia  y  SILVA, Antonio. Considerations on the reduction/extension of the permanent preservation areas of the marginal watercourse in three areas in the Paraíba do Sul River - RJ, Brazil. GOT [online]. 2017, n.11, pp.125-147. ISSN 2182-1267.  https://doi.org/10.17127/got/2017.11.006.

In Brazil, the marginal watercourse areas (FMPs) are permanent preservation areas (APPs) protected by the Forest Code (Law 12.651/2012). Urban or consolidated APPs are vulnerable to floods and inundations. In this scenario, three areas of consolidated APPs / FMPs are compared in different geological-geomorphological contexts along the Paraíba do Sul River (in the State of Rio de Janeiro). Area 1 (Resende), Area 2 (Paraíba do Sul-Três Rios) and Area 3 (Campos dos Goytacazes). The objective is to evaluate the possibility of enlargement/reduction of the consolidated APPs/FMPs, in accordance with the legal regulatory instruments. As for the methodology, land-use mapping and characterization with field-validation, using ArcGis 10.3 software was performed. According to the results, it is concluded that it is possible to change the dimensions of these areas provided that detailed studies are elaborated when the intervention is requested.

Palabras clave : Areas of permanent preservation of marginal strip of watercourse; River Paraíba do Sul; Land use in FMPs; APPs in urban areas.
