The Amazon Basin is experiencing large-scale land use conversion from primary forest to pasture. While several land cover datasets map cleared areas in the Amazon, the percent cover of woody vegetation (trees and shrubs) in cleared areas and its association with clearing age, soil type, and geology is poorly understood, despite its importance for c...

A gestão eficiente de recursos hídricos depende da qualidade da representatividade espacial e temporal dos dados de precipitação. O objetivo deste estudo foi realizar uma análise comparativa dos dados de precipitação provenientes da Tropical Rainfall Measuring Mission (TRMM) e do produto MERGE do Centro de Previsão do Tempo e Estudos Climáticos (CP...

Land cover changes (LCC) affect the water balance (WB), changing surface runoff (SurfQ), evapotranspiration (ET), groundwater (GW) regimes, and streamflow (Q). The Tapajós Basin (southeastern Amazon) has experienced LCC over the last 40 years, with increasing LCC rates projected for the near future. Several studies have addressed the effects of cli...

Accelerated land use changes in the Brazilian Amazonian region over the last four decades have raised questions about potential consequences for local hydrology. Under the hypothesis of a lack of frontier governance, projections of future changes in the Amazon basin suggest that 20–30% or more of this basin could be deforested in the next 40 years....

A qualidade dos resultados depende da acurácia dos dados disponíveis. Dados topográficos de todo o globo, provenientes da SRTM - Shuttle Radar Topography Mission, são disponibilizados gratuitamente. Se corretos, estes dados constituem recurso poderoso para o planejamento territorial e ambiental. O objetivo deste trabalho foi verificar o grau de sem...

Land cover change such as replacing the forest with pasture or bare soil areas can significantly affect the water cycle, altering streamflow regime, accelerating or intensifying erosive processes and influencing water quality and availability. In Crepori River basin, the expansion of gold mining activity has caused an increase in sediment concentra...

Accelerated land use change in the Amazon biome over the last decades has raised questions about the extent and consequences of the impacts on the local hydrology. Land cover patterns control surface runoff, infiltration, evapotranspiration and sediment production within the watershed, directly influencing the streamflow dynamics and sediment yield...

Digital image classification is a useful process to characterize the land cover and the land-use by analyzing the target’s spectral and spatial patterns. Digital image processing involves a manual or automatic process for the distinction of targets based on visual and statistical parameters. This study aimed to analyze the accuracy of two supervise...

Empirical Analysis of Fragility of Natural Environments (EAFNE) gives support to the territorial planning of areas in the urban expansion process. Once the EAFNE method is sensitive to land use and land cover data, it is necessary that this type of mapping is highly accurate. Given the high level of accuracy that can be obtained on land use/land co...
