Os impactos da mudança do código florestal na microbacia Sanga Mineira no município de Mercedes-PR

Abstract

The Sanga Mineira microbasin belongs to the Paraná watershed 3 and is considered one of the main water reservoirs of the municipality of Mercedes, having in its territory 120 properties that have as main source of income the agriculture and livestock. For the expansion of monoculture areas, many areas of Legal Reserve and Permanent Preservation are being destroyed by farmers, causing a series of environmental imbalances. Thus, through the above, the research aimed to quantify the legal reserve (RL) and permanent preservation (APP) areas in the Sanga Mineira microbasin, using the Georeferenced Information System (GIS), in addition to detecting the main changes that occurred as a result of the Forest Code change, to assess whether the new laws have helped to improve environmental sustainability. As a technical methodological procedure, the SPRING program was used, 97 properties were evaluated, of which three main land use classes were verified: Permanent preservation area, Legal Reserve Area and Total Consolidated Area. It was concluded that there was a decrease in the areas of legal reserve, and an increase in the areas of APP's and total consolidated area.
