High-resolution aboveground carbon changes in the Brazilian Amazon using repeated airborne lidar.
The Brazilian Amazon is a hotspot of deforestation and forest degradation caused by logging, fire, and deforestation-associated fragmentation and edge effects. While the extent of deforestation and associated carbon losses are relatively well known, the quantification of the carbon losses caused by ...

Quantifying carbon loss at forests degraded by logging with repeated airborne Lidar data in the Brazilian Amazon.
Forest degradation is a major issue and a key component of tropical forests and carbon emissions. In this study, we use repeated Airborne Laser Scanning (ALS) data to quantify carbon losses in degraded forests due to logging at the Mato Grosso state rainforests. We identified logged areas using Plan...

Proposal of an Agricultural Vulnerability Stochastic Model for the Rural Population of the Northeastern Region of Brazil.
Agriculture is the worlds main economic activity. According to the Intergovernmental Panel on Climate Change, this activity is expected to be impacted by drought. In the Northeast region of Brazil (NEB), most agricultural activity is carried out by small rural communities. Local socio-economic data ...

State-of-the-Art and Framework for Identifying Urban Patterns by Remote Sensing Data.
The increase in the spatial resolution of satellite imagery and the greater distribution of data have enabled the use of remote sensing for urban studies. However, there is still a lack of databases and cartographic publications for cities in the Brazilian Amazon. Thus, the following questions guide...

Flood-prone areas based on physiographic indices and multi-criteria assessment for the basins of Ubatuba, on the mountainous North Coast of São Paulo State, Brazil.
The municipality of Ubatuba, São Paulo State, Southeast Brazil, is known for its strong orographic rainfall as a result of moisture fronts in the Atlantic Ocean, morphological structure, and abrupt relief of Serra do Mar. These conditioning combinations reinforce the occurrence of natural disasters...

Greening and Water Use Eciency during a period of high frequency of droughts in the Brazilian semi-arid.
A discussion that has occurred in the scientific community is that despite the increase in the frequency of droughts, the semi-arid world may be increasing the density of vegetation due to fertilization by the increase in atmospheric CO2, a phenomenon called greening. Through this study, we sought t...

A mathematical programming approach for downscaling multi-layered multi-constraint land-use models.
Land-use and land-cover change (LULCC) models are important tools for environmental policy planning. LULCC models are frequently constrained to the generation of projections at a specific resolution. However, subsequent studies or models may require finer resolutions. In this work, a downscaling met...
