Solar energy and the water, energy and food nexus: Petrolina-Juazeiro case study, Brazil.
Water, energy and food are essential resources for society. Their integrated management, based on synergies and trade-offs, is determinant to attend the demand in long-term. Petrolina and Juazeiro are cities in Brazilian semiarid where coexist: the Sobradinho hydropower (4,214 km² reservoir) and a ...- por Portal Padrão

Estimating the above ground biomass of brazilian Savanna using multi-sensor approach.
The Brazilian Savanna, known as Cerrado (Cerrado sensu lato (s.l.)), is the second largest biome in South America. It comprises different physiognomies due to variations of soil, topography and human impacts. The gradients of tree density, tree height, above ground biomass (AGB) and wood species cov...- por Portal Padrão

Atmospheric concentrations and dry deposition of reactive nitrogen in the state of São Paulo, Brazil.
Estimates of nitrogen deposition play a key role in better understanding the human impacts on the nitrogen biogeochemical cycle. This paper examines the concentration of reactive nitrogen (Nr) in the atmosphere and the average dry deposition in the state of São Paulo, Brazil. The Nr species that we...- por Portal Padrão

Avoiding invalid transitions in land cover trajectory classification with a compound maximum a posteriori approach.
Classifying remote sensing time-series in land cover trajectories can provide essential information about ecosystems functioning and about the impacts of natural phenomena or human activities over the environment. The existing approaches commonly used for this task can present serious drawbacks, suc...- por Portal Padrão

A spatiotemporal database on the energy, macro and micro-nutrients from the Brazilian agricultural production.
To construct this database, we integrate the nutritional content of 62 crops and 5 livestock categories to estimate the amount of 21 macro and micro-nutrients (including energy) that were produced from agriculture in each Brazilian municipality during the last three decades. Additionally, we allocat...- por Portal Padrão

A worldwide meta-analysis review of restriction criteria for landfill siting using geographic information systems
One of the most crucial parts of solid waste management is determining landfill site location, since multiple factors must be considered and there is no universal formula. The main purpose of this study is to make a worldwide systematic review of restriction criteria used for landfill siting using g...- por Portal Padrão

Comparison of cloud cover detection algorithms on sentinel-2 images of the Amazon tropical forest.
Tropical forests regulate the global water and carbon cycles and also host most of the worlds biodiversity. Despite their importance, they are hard to survey due to their location, extent, and particularly, their cloud coverage. Clouds hinder the spatial and radiometric correction of satellite image...- por Portal Padrão

Multi-source change detection with PALSAR data in the Southern of Pará state in the Brazilian Amazon.
Optical data is broadly used for change detection studies, despite being hindered by atmospheric conditions. Synthetic Aperture Radar (SAR) data can be useful for change detection in areas with frequent cloud coverage as SAR systems are capable of obtaining images almost independently from atmospher...- por Portal Padrão
