| ABSTRACT Soil erosion is currently one of the main concerns in agriculture, water resources, soil management and natural hazards studies, mainly due to its economic, environmental and human impacts. This concern is accentuated in developing countries where the hydrological monitoring and proper soil surveys are scarce. Therefore, the use of indirect estimates of soil loss by means of empirical equations stands out. In this context, the present study proposed the assessment of the Revised Universal Soil Loss Equation (RUSLE) with the aid of Geographical Information Systems (GIS) and remote sensing for two agricultural watersheds in southern Rio Grande do Sul - Brazil. Among all RUSLE factors, LS showed the closest patterns to the local when compared to the... |

| ABSTRACT: Since colonial times, Brazilian land use has been made under an extractivist model at the expense of deforestation, increasing soil and vegetation depletion, stream siltation, as well as loss of biodiversity. An ecological-economic zoning (EEZ) has been taken as feasible alternative to guide public policies aimed at city land-use planning. This study focused on designing an EZZ for the city of Altinópolis, in São Paulo state (Brazil), by means of geographical information systems (GIS). Information and maps delineated six land-use areas, in which 30% covered areas under environmental protection, 45% over areas with groundwater recharge potential, which should be intended to restoration. Furthermore, around 70% of the territory show potential to be... |

| Os dados básicos para estimar a evapotranspiração de referência de Penman-Monteith FAO (EToPM) são: temperaturas máxima e mínima, pressão de vapor real ou atual, radiação líquida e velocidade do vento, muitas vezes indisponíveis por requererem estações meteorológicas específicas. O objetivo deste trabalho foi avaliar a adequação do método para estimar a EToPM, utilizando-se dados mínimos integrados a um Sistema de Informação Geográfica, na bacia do Rio Jaguaribe, CE. Foi utilizado o sistema integrado de modelagem regional PRECIS (Providing Regional Climates for Impacts Studies), versão 1.2, com as condições de contorno do Modelo Climático Global (HadAM3P), acoplado ao Modelo Climático Regional (HadRM3P), por meio da técnica dinâmica de redução de escala... |

| The quantification and integration of ecosystem services (ES) into urban planning decisions is becoming increasingly important. However, studies that quantify and analyze the impacts in terms of ES changes are still scarce. We analyzed multiple ES provided by the landscape of the Urban Community of Bordeaux (CUB), in France, between 1990 and 2006 as a result of land use and cover change (LUCC) with Corine Land Cover and other open data. These ES were selected with the help of local stakeholders and were calculated using a spatially explicit modeling approach with InVEST and own-produced models. It was found that all ES, except erosion regulation, have decreased as a consequence of LUCC. Results also suggest that LUCC change decisions which do not consider... |
