The understanding that air transport induces the economic development of a region has motivated studies on regional air transport and the necessary subsidies for its implementation. Several countries have implemented specific subsidy plans with a focus on integrating their territories through a network of air routes, depending on the funding method...

Regularized Indigenous Lands (RILs) located entirely in the state of Rondônia, in the southern amazon. The entire historical series of active fire data (from 1998 to 2020) were obtained to achieve the objectives , and nine Landsat-OLI scenes from September 2020 were processed. The active fire data dynamics revealed that the correlation coefficient...

Researches on the deforestation of the Amazon have gained prominence in the last recent years, mainly with the change in the policy regarding the facing of this phenomenon by the Brazilian government.

Protected areas (PAs) help in strategies for maintaining biodiversity and inhibiting deforestation of the Amazon rainforest. However, there are few studies that evaluate the effectiveness of lands protected by states (or federation units). Our goal was to compare land use change over 35 years in state-level PAs with another area with another area o...

The objective of the study is to perform the spatial analysis of the conditioning factors for the increase in the incidence rate of dengue cases in municipalities located in the Amazon biome, in the period from 2016 to 2021. Three statistical approaches were applied: Moran's index, ordinary least squares regression, and geographically weighted regr...

Wild animal trafficking is a growing practice worldwide and a complex problem that brings a lot of profit, moving billions of dollars. This illegal trade has Brazil as route due to its rich biodiversity. It is widespread throughout the state of Pernambuco, having constant growth because the state is in a geographical position that favors this type...

Wild bird trafficking in the state of Pernambuco has negatively impacted the local biodiversity and accentuated the ecosystems' imbalance. This crime has proven itself as a threat to the Brazilian and global biodiversity, which causes the extinction of several species, especially the avifauna, considered the most trafficked group. The goal of this...

Using social disorganization theory, the present study considers the concentration of racial minorities and the degree of ethnic heterogeneity to provide an estimation of homicide rates in the Northeast region of Brazil. Three hypotheses were considered: (1) there is a positive association between homicides and ethnic heterogeneity and black/indige...

In the classification of images for land cover and land use mapping, several methods can be applied, however, they can present different results in relation to field truth. Therefore, the objective of this work was to test techniques for classifying high spatial digital images obtained from the Google Earth Pro® platform. The images refer to a sect...

The regional economic growth promoted by air transportation has fomented investigation into regional air transportation and the required incentives for its development. According to the types of financing used and the results of the investments, several countries have established particular subsidy strategies aiming to integrate their regions throu...

The construction and expansion of highways aiming to improve the integration of the most isolated regions in Brazil facilitated the access to many inhabited areas in the Amazon biome, but had as a consequence assisted the degradation of many of these regions. Over the last two decades , we have observed in this biome a gradual diversification and i...

The Caatinga biome is the largest and wettest semi-arid environment globally, occupying 10% of the Brazilian territory. Half of the original vegetation from the Caatinga has already been deforested. This research aims to identify the factors associated with Caatinga deforestation (2010–2016). Therefore, the researchers used Geographically Weighted...

COVID-19 is currently considered one of the greatest threats to health, safety, and the economy worldwide. An intense movement of international passengers may be critical for either the contingency or the spread of disease in a pandemic situation. Various research on international and national epidemics and their evolution have already been address...

The indigenous lands (ILs) from the Brazilian Amazon are in constant threat, especially regarding deforestation. This research aims to assess whether deforestation occurring outside ILs, in their Area of Direct Influence (ADI), influences the removal of vegetation within their areas, in the period from 1988 to 2021. We applied a log–log linear regr...

This article aims is to apply a methodology to identify Trip Generating Territories (TGT) in order to discuss the relationship between transport and land use. To achieve this goal, indirect methods were applied through digital processing of orbital remote sensing images along with spatial analysis, using the Kernel Density Estimation (KDE) method....

Objectives: To analyze the spatial distribution of rates of COVID-19 cases and its association with socioeconomic conditions in the state of Pernambuco, Brazil. Methods: Autocorrelation (Moran Index) and spatial association (Geographically Weighted Regression) models were used to explain the interrelationships between municipalities and the poss...

The irregular waste disposal is a reality that affects the Brazilian coast. The present study aimed to evaluate the environmental perception of beach users in relation to the production and disposal of solid waste at Tamandaré beach - Brazil. It was applied a questionnaire and carried out a quali-quantitative collection that has shown that the impa...

The purpose of this research is to verify the influence of the vaccination of COVID-19 on air demand in the United States of America. Several daily data (from January 2019 to March 2021) were used on the research, such as: aircraft movements at American airports, people vaccinated in the country. Also, variables dummies: the pandemic period and the...

Traffic accidents have awakened a global concern as they are the ninth leading cause of death worldwide. This triggers a challenge for traffic managers and planners interested in ensuring the fluidity of traffic and also road safety. In this context, spatial analyzes are essential to recognize critical points or stretches on the road and thus contr...

Using public transport systems has been reported to be a possible vector of virus transmission during epidemics. In this context, this article aims to analyze the spatial correlation between public transportation users and COVID-19 cases, using Recife (PE) as a case study. Using spatial analysis, the Moran I Global and Local index were calculated,...

Homicide rates have been increasing worldwide, especially in Latin America, where it is considered one of the most lethal of the continents. Despite that, the occurrence of homicides are not homogeneous in time and space on the continent or in the Brazilian cities. Therefore, the main objective of this study is to present a spatial analysis of homi...

RESUMO O novo coronavírus se espalhou rapidamente pelo mundo, promovendo a transmissão comunitária e local aos cidadãos. Em Pernambuco, os casos de pacientes infectados pela COVID-19 se enquadram entre um dos maiores índices no país. A capital do estado comporta o Aeroporto Internacional do Recife (REC), principal porta de entrada de passageiros in...

Identification of development poles within the regional planning is important for defining the nodes of a given transport network and plays the role of driving economic growth in a region. Nevertheless, such proceedings are complex, especially in some areas where there is a lack of data that could support studies of this nature, for example in the...

The great navigations showed the need to know the ways to go to reach the desired destination. When Brazil was discovered mapping was a necessity to maintain the colony. There were many attempts to obtain a part of the Portuguese Colony from European countries. The first mappings of the Brazilian territory occurred when the hereditary captaincies w...
