| Environmental analysis and zoning were carried out for management purpose of the Longines Malinowski Municipal Park (LMMP). With an area of 24.85 ha, this urban park includes a patch of sub-tropical humid forest, completely surrounded by residential and commercial areas in the City of Erechim, Rio Grande do Sul State,Brazil. Landscape features derived from aerophotogrametric maps, based on the use of Geographical Information Systems (GIS-IDRISI), resulted in several thematic maps, through which a proposal of environmental zoning was perfomed, observing the definition of five zones of use. The environmental diagnosis identified several types of activities potentially harmful to the biodiversity of the LMMP and city's environmental quality. The... |

| Climatic mapping in the Bío Bío and La Araucanía Regions of Chile is primarily in analog form (paper) and delineation of contours, making it unsuitable for digital handling by geographic information systems (GIS). Therefore, in this study, topoclimatic models were created and spatially represented to explain the spatial and temporal variation of monthly mean temperature and precipitation, as a function of variability and singularity of the physiographic characteristics of the Bío Bío and La Araucanía Regions. The physiographic factors considered were latitude, longitude, altitude, aspect and distance to coastline. To elaborate equations, data from thermopluviometric stations of the study area were compiled and systematized. These stations were standardized... |

| Abstract Soil erosion can be accelerated by agricultural intensification, and the soil loss can alter the quality of water bodies. Sustainable agricultural production therefore requires the management of erosion and potential water pollution. In Uruguay, where there is heavy use of soil for agriculture, there is a need to continually develop and update erosion management policies. In this framework, we estimated the erosion in 99 drainage basins by analyzing and managing the information required (K, L, S, C and R-factors) in the universal soil loss equation (USLE) and the revised universal soil loss equation (RUSLE) in a geographical information system (GIS). The studied drainage basins encompass 73% of the area of Uruguay. The results include the... |

| In a hydrographic watershed, the erosionability (K factor) of the soil evaluation depends on the technical resources, developed applied sciences, and spatial technology available. For the determination of erosionability in the watershed of Pillahuinco Grande s Creek (Argentina) (38°S, 61°15'W), the Universal Soil Loss Equation (USLE) was used by applying a geographic information system (GIS) for the cartographic evaluation. A database of geological, environmental, and soil associations was developed, which indicated that geomorphologic variability, caused by geology and soil, significantly determines the spatial variation of the K factor values, in a range from 0.02 to 0.69 ((t·m²·h)·(ha·J·cm)-1). A new quantification was determined with the simplified K... |
