The Brazilian Institute of Geography and Statistics (IBGE) launched today (30) the first edition of the 69th volume of the Journal of Brazilian Geography. The special edition marks the birth centenary of two major names of the Brazilian Geography, in the field of Geomorphology, Antonio Teixeira Guerra and Aziz Ab’Saber. As a tribute, the volume makes available the access links to the works of Antonio Teixeira Guerra and Aziz Ab’Saber published on the RBG. The edition also brings three articles, a technical note, two essays, two interviews and a mapping. 

"After a long time, we designed the cover of the Journal without any spatial analysis. We decided to include Guerra´s and Ab'Saber´s photographs. This year, we are celebrating their birth centenary, two important geomorphologists in Brazil. We are including in the celebration of the centenary a mapping pinpointing the areas of the Brazilian territory studied by Ab'Saber, making visible his work as well as Guerra´s, who worked at the IBGE," explained Maria Lúcia Vilarinhos, editor-in-chief of the journal. 

Antonio Teixeira Guerra contributed with the "Geological-Geomorphological Dictionary", originally published in 1954 by the Pan-American Institute of Geography and History´s Geography Commission. Later editions, up to 1993, were released by the IBGE. In addition to the Dictionary, Guerra published a number of articles and other works at the IBGE, RBG and Geographical Bulletin. Access links to the digital version are available in the end of the 69th edition of the Journal. 

This edition includes an essay of Rosangela Garrido Machado Botelho and André Luiz Ferreira, geographers and geomorphologists of the IBGE´s Coordination of Environment of the Directorate of Geosciences. Botelho produced a master´s thesis at the Federal University of Rio de Janeiro (UFRJ) under the orientation of Professor Antonio José Teixeira Guerra, Antonio Teixeira Guerra´s son, allowing a deep knowledge of the geographer´s life. The essay addresses Guerra´s professional career and intelectual production. The edition also interviews Antonio José Teixeira Guerra, Professor of the UFRJ´s Department of Geography on the life and work of his father. 

As a tribute to Professor Aziz Ab’Saber, the edition brings a mapping pinpointing localities and regions surveyed by him, which resulted in articles and works. Those published by the RBG have their links available in the end of the edition. The mapping is based on the Interactive Geographic Platform (PGI), developed bythe IBGE´s Directorate of Geosciences. It also includes an interview with Professor Jurandyr Sanchez Ross, geographer and geomorphologist of the Department of Geography of the Univeristy of São Paulo (USP), an innovator in this field in Brazil, talking about his interaction with Ab'Saber and his influence on Ross´s formation. 

Beyond the tributes, the major highlights in this edition are three articles. Called “Potential of cartography for the study of the real estate dynamics: Case study in Niterói, RJ”, the first article from Rômulo Weckmüller Vieira, of the University of the State of Rio de Janeiro (UERJ), Rubens Moreira Carvalho and Daniel Sanfelice, both of them of the Federal Fluminense University(UFF), based on newspaper advertisements between 1970 and 2010 and data of real estate transactions in the municipality of Niterói between 2014 and 2021, to analyze the urban expansion of the city. The authors showed the vectors of the real estate transformation, growing and stagnant regions and valuation periods of the real estate in that municipality. Botelho explains that the article uses mapping to analyze the urban dynamics of the occupation and expansion of the city. 

The second article, called "Recent changes (1987-2019) of the eastern riverside of the mouth of Pará River, dominated by high tide (Eastern Amazon-Brazil)" quantifies the areas in erosion or accretion of the coastline of the eastern riverside of Estuary of Pará River, and uses a multitemporal analysis through Landsat satellite images (1987 to 2019), indicating the general predminance of accretion of the coastline. Authors Diandra Karina Martins Guimarães, Maâmar El-Robrini, Renan Peixoto Rosário and Rafael Alexandre Alves Menezes are from the Federal University of Pará. "The article is an analysis of a highly complex estuary, a mixture of fresh water and saltwater. It is a time analysis to check whether Pará River eroded more in its mouth, whether silts were added or withdrawn. They analyze a given period of time and images show that Pará River more laid sitls down than withdrew," explained the editor-in-chief of the journal. 

The third article, from Laymara Xavier-Sampaio, Liana Rodrigues Queiroz, Manuella Maciel Gomes, Maria Ligia Farias Costa, Maria Elisa Zanella and Marcelo Freire Moro, of the Federal University of Ceará, raises, based on geoprocessing techniques, the total number of areas of residual vegetation in the municipality of Fortaleza, calculating the total extension of areas inside conservation units and the degradation degree of its vegetal cover, as well as measures the total residual areas under legal protection of the National System of Conservation Units. "The article measures the efficiency of the conservation units in the city. Authors surveyed and analyzed the effectiveness of the conservation, i.e., whether creating such units really protects conservation areas," pointed out Vilarinhos. 

Authored by Jefferson Gomes, of the Federal University of Catalan, Lara Luíza Silva and Silvio Carlos Rodrigues, both of them from the Federal University of Uberlândia, the technical note “semi-automatic double-ringInfiltrometer of slightly variable load” aims at presenting the use of this equipment. Valdir Roque Dallabrida´s essay, of the Regional University of the Northwest of the State of Rio Grande do Sul, addresses the discussion on development based on the Brazilian territory. 

"Whenever we release an edition, we are already working in the next number. After releasing this number, we will launch a brief on urban weather, in which a group of professors of the Federal University of Viçosa will select the articles of this up-to-date subject. We have also another brief, which are articles from researchers of the UFRJ and other universities on field work in geography in Jalapão, Tocantins. We are already working in these two subjects, we have already received some articles and we expect that the next year edition will be a robust one," concludes Maria Lúcia Vilarinhos. 

About the Journal of Brazilian Geography

Published by the IBGE, the Journal of Brazilian Geography (RBG) is one of the oldest and most respected Brazilian technical-scientific publications in the area of Geography and related sciences. With brief interruptions, the RBG was published on a four-month period for nearly 70 years, from 1939 to 2006, being considered a journal of reference.

Many articles opened important knowledge frontiers, becoming classic articles in Brazil and abroad. In 2016, the IBGE resumed the publication in a new format - as a semi-annual electronic edition.
