Georeferenced Information System as a Tool in the Quantification of Protection Areas

The use of georeferenced systems has been widely used to obtain data on the quality of the environment, aiming to quantify how areas are being occupied, and how natural reserves are being affected as a result of human action. The Sanga Mineira microbasin belongs to the Paraná basin 3 and is considered one of the main water reservoirs in the municipality of Mercedes, with 120 properties in its territory, whose main source of income is 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 areas of Legal Reserve (RL) and Permanent Preservation Area (PPA) 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 change in the Forest Code, to assess whether the new laws have helped to improve the sustainability of the environment. Methodological technical procedures the SPRING program was used to evaluate 97 properties, of which the 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 Legal Reserve areas and an increase in the areas of APP’s and Total Consolidated Area.
