    This essay had the aim of evaluating the fragility and the conflict of the use of soils from six watersheds on the recharging area of Guarani Aquifer, on the Rio das Cinzas’s medium watershed, Norte Pioneiro Paraná. From the using of geotechnologies and the Boolean logic for maps creation, it was possible to gather data referring to the current use of the soil, erosion’s natural potential (ENP), agricultural aptitude of the grounds and to end, the analyses of the conflict of the soil’s use. These are essential studies to prevent environmental impact, whose results enable planning in search of sustainability. The results demonstrated the high potential of soil loss, confirming the fragility of the region. In relation to the uses, it was found all the predetermined sorts, water, urban, forest, silviculture, farming and pasture, standing out the last two ones. The lands of the study area of the search shows a lot of agriculture aptitudes, from the good for farming up to the regular for pasture. The analyses’ result about the conflict of the soil’s use demonstrated the lack of planning when choosing the cultivation implanted, presenting vast areas with underutilization of the soil and some of them with overutilization. This lack of planning combined with the fragility in potential presented's by the soils might bring about significant losses, less agricultural productivity and direct impacts on Guarani Aquifer’s recharging.

    Fragmentos florestais e métricas de ecologia da paisagem no município de Bandeirantes - PR

    The expansion of agricultural crops and pasture areas was responsible for most of the deforestation in the municipality of Bandeirantes, Paraná. In this study, landscape fragmentation and its temporal evolution were evaluated by applying landscape ecology metrics in the period corresponding to the 1970s and 2012 (42 years), comparing the results of the metrics regarding their ability to demonstrate causes and consequences of forest fragmentation. The study area is located in the municipality of Bandeirantes-PR, situated between the coordinates 50°25'44" to 50°16'43" W and 23°14'05" to 23°05'59" S. Assessments of deforestation and degree of fragmentation were carried out using remote sensing data and landscape analysis. The results revealed that there was a reduction in the number of fragments between the periods: in 1970, 634 fragments, and in 2012, 312 fragments, which corresponds to 322 fragments less, and in percentage this is equivalent to 49% of the examined area. The study area has been undergoing landscape transformations since 1970, and the degree of fragmentation of native vegetation areas was replaced by temporary and permanent crops and pasture. Thus, the results of this study indicate that deforestation affected almost half of the natural vegetation until 2012, aggravating the integrity of native vegetation fragments in the study area.
