Using Remote Sensing to Quantify the Joint Effects of Climate and Land Use/Land...

Jardim, Alexandre Maniçoba da Rosa Ferraz; Araújo Júnior, George do Nascimento; Silva, Marcos Vinícius da; Santos, Anderson dos

Caatinga biome, located in the Brazilian semi-arid region, is the most populous semi-arid region in the world, causing intensification in land degradation and loss of biodiversity over time. The main objective of this paper is to determine and analyze the changes in land cover and use, over time, on the biophysical parameters in the Caatinga biome in the semi-arid region of Brazil using remote sensing. Landsat-...


Diagnosis spatiotemporal of fire foci in Brazil

Santos, Carla Taciane dos; Correia Filho, Washington Luiz Félix; Oliveira-Júnior, José Francisco de; Santiago, Dimas de Barros; Batista, Bárbara Alves

The emergence of forest fires may be of anthropic or natural origin, both of which cause significant socio-economic and environmental damage, and in the good part of these occurrences are resulting from Fire Foci (FF) occurrence. In recent years, Brazil has suffered from a significant increase in FF, resulting in large fires. In this way, the objective of the present study was to diagnose the spatiotemporal FF ...

Silva, Silvania Donato da; Oliveira-Júnior, José Francisco de; Correia Filho, Washington Luiz Félix; Barros, Heliofábio Gomes; Souza, Edson de Oliveira

The aim of the study was to evaluate the reported cases of dengue in the State of Alagoas via applied statistics and geospatialization.Dengue data were obtained from the DATASUS system between 2000 and 2015. The time series was submitted to descriptive and exploratory statistics and the Pettitt test. In the dengue case maps, the Spline method via QGis version 3.4 was used. In descriptive statistics, only 10 mun...

Pobocikova, Ivana; Souza, Amaury de; Abreu, Marcel Carvalho; Oliveira-Júnior, José Francisco de; Santos, Cícero Manoel dos; Lins, Taynã Maria Pinto

The most significant and influential meteorological element in environmental conditions and human activities is precipitation. The objective of this study was to adjust eight probability distributions to monthly, seasonal and annual rainfall data in the Pantanal of Mato Grosso do Sul, Brazil, using a time series of data (1983-2013) by the National Meteorological Water Agency (ANA). The performance evaluation of...

Non-parametric tests applied to reported cases of dengue in the southeast regio...

Oliveira-Júnior, José Francisco de; de Gois, Givanildo; da Silva, Elania Barros; Silva Junior, Carlos Antonio; Teodoro, Paulo Eduardo

Dengue is one of the biggest problems of global public health in developing and underdeveloped countries. Nowadays, researchers in climate changes are concerned about the impact of these changes on human health, particularly with increased this epidemic. Dengue is among the largest public health problems in Brazil and is higher in the months with high temperatures, which is the Aedes aegypti's reproductive peri...

Cluster analysis identified rainfall homogeneous regions in Tocantins state, Br...

Oliveira-Júnior, José Francisco de; Xavier, Fábio Miranda Gomes; Teodoro, Paulo Eduardo; Gois, Givanildo de; Delgado, Rafael Coll

Identifying homogeneous regions regarding the monthly rainfall is relevant in agricultural planning, especially in relation to the installation of crops. Thus, the aim of this study was to apply the cluster analysis using Ward's algorithm to identify homogeneous regions in Tocantins State. Rainfall database of 34 stations (sites) of Tocantins, from 1976 to 2012, it were obtained of the Database of the Agência N...

Models to estimate incident solar radiation on Seropédica, Rio de Janeiro

Gois, Givanildo de; Souza, Jessica Cristina Santos; Oliveira-Júnior, José Francisco de; Delgado, Rafael Coll; Lyra, Gustavo Bastos

Incident solar radiation (Rs) is usually used as an input variable in growth simulation models and yield of agricultural crops, in the design of alternative energy systems, buildings desing, weather, irrigation projects and food preservation, among others. However, in Brazil, there are few studies that evaluated the performance of different models in estimating Rs. Therefore, the aim of the study is to evaluate...
