Land use and cover change (LUCC) in Brazil encompass a complex interplay of diverse factors across different biomes. Understanding these dynamics is crucial for informed decision-making sustainable land management. In this study, we comprehensively analyzed LUCC patterns drivers using 30 m resolution MapBiomas Collection 6.0 data (1985-2020). By mapping deforestation primary secondary natural vegetation, vegetation regeneration, transitions between pasture, soybean, agriculture, irrigation,...
O estudo das alterações climáticas e de eventos extremos torna-se importante devido ao impacto que estes podem ocasionar. A partir da série precipitação diária (1982 a 2015) Pelotas/RS/Brasil, objetivou-se neste trabalho: (i) detectar as possíveis tendências na precipitação; (ii) relacionar os aos sistemas meteorológicos ocasionaram; (iii) analisar influência Oscilação Decadal do Pacífico (ODP) variabilidade interanual. Para análise tendência, foi aplicada às séries total anual trimestral o...
ABSTRACT Ensuring prompt and effective water quality monitoring is increasingly important. Remote sensing has been shown to be an tool for simplifying speeding up this process. The aim of study develop empirical model map the spatial temporal dynamics turbidity in Mirim Lagoon, located southern Brazil. To achieve this, Sentinel-2A/B MSI sensor data were combined with collected situ. was applied monthly images (with cloud cover ≤ 20%) 2019 2020 using Google Earth Engine (GEE) platform. Mean...
The Environmental Impact Assessment (EIA) is a process that consists in the identification, prediction and evaluation of impacts human activities have potential to cause significant on environment. It analyses whether certain high for degradation impact, order judge or not such can be implemented and, if they are, mitigate compensate their negative impacts. Therefore, aim this study was analyze applied methods environmental licensing Belo Monte Hydroelectric Facility through qualitative...
A caracterização fractal da rede de drenagem uma bacia hidrográfica surge necessidade se compreender a ocorrência fenômenos hidrológicos, considerando influência fatores geomorfológicos.Desta forma, características físicas e fractais integram elementos importantes para análise seu comportamento hidrológico.Assim, o objetivo deste trabalho foi estimar dimensão sub-bacias com diferentes pelo método Box-Counting (Contagem Caixas).Além disso, verificou-se relação existente entre cursos fluviais...
Mirim lagoon is the second largest lacustrine water body in Southern Brazil, providing for local communities. However, algae growth and quality tributaries rivers influenced by nutrient's increase. In this context, study performs empirical semi-empirical chlorophyll-a (Chl-a) modeling using remote sensing situ data assessment. Water were collected at 15 sample locations on date of Sentinel-2 satellite overpass. Surface reflectance derived from Sen2Cor atmospheric correction method correlated...
A avaliação de impacto ambiental (AIA) é um processo identificação, previsão e atividades com potencial causar impactos significativos. participação pública uma etapa extremamente importante desse processo, podendo influenciá-lo diversas formas em diferentes momentos. Esta pesquisa busca avaliar a importância do envolvimento da na AIA, analisando os métodos no licenciamento usina hidrelétrica Belo Monte - PA, através qualitativa, o estudo (EIA) empreendimento dessas ações população. Pôde-se...
Municipal solid waste (MSW) increasing generation is related to population growth and higher consumption patterns. MSW management still considered an issue for Brazilian municipalities due its high complexity, specificity amount. Landfills are a suitable method final disposal of waste, being the technique used in Brazil. Among numerous applications, Geographic Information Systems (GIS) have been widely applied select sites landfills implementation. To meet regulatory requirements, choosing...
Both SHPs selected for this study SHP Cabuí (southeast of Minas Gerais state) and Caiçara (northern are located in low-income regions. This aimed to evaluate the approach used describe socio-environmental impacts - through analysis attributes magnitude these two projects this, consultations were carried out on Environmental Impact Studies (EIS) presented by SHPs, as well technical opinions available website agency responsible environmental licensing (IBAMA). It was verified that approaches...
Oil spills can threaten the environmental quality of coastal ecosystems. The impact accidents this type is significant and it important to understand them in order assess magnitude such accidents. In way, present work aimed discuss some main impacts that be caused by oil spill marine terrestrial environments, besides presenting a review cleaning processes for recovery these degraded areas. addition, study elaborate Program Recovery Degraded Areas (PRAD) aiming plan case study: leakage region...
ABSTRACT Calibration of hydrologic models estimates parameter values that cannot be measured and enable the rainfall-runoff processes simulation. Multi-objective evolutionary algorithms can make calibration faster more efficient through an iterative process. However, standard stopping criterion used to stop process is reach a pre-defined number iterations defined by modeller. Alternatively, Ticona based on minimum required achieve determined non-dominated solutions in Pareto front, resulting...
RESUMO O presente trabalho consiste na avaliação da existência de risco e sua quantificação em casos vazamentos derivados do petróleo uma refinaria localizada Região Sudeste Brasil. A área apresenta solo subsuperficial água subterrânea contaminados por hidrocarbonetos outras substâncias consequência funcionamento refinaria. Foram consideradas as vias exposição inalação aos contaminantes presentes nesses dois meios. câncer quociente perigo foi realizada para cada substância química,...
