“…The first paper that applied statistical validation methods was published in 2015 [52]. Between 2015 and 2021, 27 articles were published and 15 out of them applied cross tabulation [36,52], success curve [26], AUC [14,16,25,35,40,42], ROC [43,46], or AUC/ROC [15,34,44,45] to validate the susceptibility maps. Two publications mentioned validation curves, but did not provide details about them [13,50].…”

“…Some of the publications highlight the importance of the developed work and the application of landslide susceptibility studies in Brazil. The authors discuss how the work can be used by research centers, universities, government, and other institutions interested in the prevention, monitoring, and forecasting of landslides [12,15,29,31,[33][34][35][36][37]41,43,44,46,50,52]. Vieira et al [28] mention the importance of models to provide relevant information about areas susceptible to landslides in a cost-efficient manner.…”

“…The study areas of each publication were analyzed based on the federal state of occurrence. Out of the 33 studies analyzed, 19 of them were in the southeast region, in the states of São Paulo (10) [15,[25][26][27][28][29][30][31][32][33], Rio de Janeiro (7) [12,[34][35][36][37][38][39], Minas Gerais (2) [16,40], and Espírito Santo (1) [41]. The remaining 14 were in the south region, in Rio Grande do Sul (8) [14,35,[42][43][44][45][46][47], Santa Catarina (4) [13,[48][49][50], and Paraná (2) [51,52] (Figure 3).…”

Landslide Susceptibility Mapping in Brazil: A Review

Landslide susceptibility studies are a common type of landslide assessment. Landslides are one of the most frequent hazards in Brazil, resulting in significant economic and social losses (e.g., deaths, injuries, and property destruction). This paper presents a literature review of susceptibility mapping studies in Brazil and analyzes the methods and input data commonly used. The publications used in this analysis were extracted from the Web of Science platform. We considered the following aspects: location of study areas, year and where the study was published, methods, thematic variables, source of the landslide inventory, and validation methods. The susceptibility studies are concentrated in Brazil’s south and southeast region, with the number of publications increasing since 2015. The methods commonly used are slope stability and statistical models. Validation was performed based on receiver operating characteristic (ROC) curves and area under the curve (AUC). Even though landslide inventories constitute the most critical input data for susceptibility mapping, the criteria used for the creation of landslide inventories are not evident in most cases. The included studies apply various validation techniques, but evaluations with potential users and information on the practical applicability of the results are largely missing.

“…The use of a multicriteria analysis method is recent in Brazil, and has been applied mainly to environmental problems which, due to the possibility of using specific criteria for each analysis, the application of the AHP method can be found in several studies, among them: geoenvironmental (Santos et al, 2007), risk of landslides (Faria et al 2016;Meirelles et al, 2018), socio-environmental vulnerability (Marques et al, 2018) and susceptibility of soil to erosion (Santos et al, 2019).…”

Analytic hierarchy process (AHP) applied to flood susceptibility in São José dos Campos, São Paulo, Brazil

The changes in environmental factors in a hydrographic basin, mainly in the urban environment, enable different scenarios than the change of parameters in climatic, physical, political, and socioeconomic factors. Those changes may have immediate effects on indigenous populations, often making them vulnerable to the risk of flooding. This article evaluates the vulnerability to flooding in the municipality of São José dos Campos, State of São Paulo, Brazil using multicriteria analysis and geoprocessing techniques. Quantum GIS (QGIS) was used in the manipulation and processing of vector and matrix data related to the terrain slope, hydrography, geotechnics, and data history of flooding (2009 - 2018) in São José dos Campos. The hierarchy and criteria weighting processes were carried out, as well as the zoning of areas at risk of flooding. Thus, it was found that 23.81% and 2.17% of the municipal territory has high and very high susceptibility to flooding. It can be concluded that the combined use of multicriteria analysis and geoprocessing is an effective contribution to assist the management of public policies in order to obtain more assertive decisions in the prevention or reduction of flood risks.

O morcego hematófago Desmodus rotundus é o principal transmissor da raiva dos herbívoros domésticos, que causa enormes prejuízos econômicos na pecuária da América Latina. Utilizando um modelo de análise de decisão por múltiplos critérios em Sistema de Informações Geográficas (SIG) foi possível integrar as informações relacionadas as variáveis “População de D. rotundus existentes nos abrigos” e “Distância Euclidiana dos abrigos de morcegos” e gerar um mapa de áreas vulneráveis a ataques de D. rotundus aos bovinos na região centro leste no estado de São Paulo - Brasil. Foram encontrados 1566 D. rotundus distribuídos em 93 abrigos em 18 municípios. A maior parte da região estudada apresentou média vulnerabilidade a ataques por D. rotundus, em três grandes regiões com diferentes dimensões, separadas por áreas de baixa e muito baixa vulnerabilidade. Os municípios com áreas vulneráveis muito altas a ataques a herbívoros por D. rotundus foram São Carlos, Araraquara, Ribeirão Bonit e Dobrada e os municípios com áreas de alta vulnerabilidade a ataques a herbívoros por D. rotundus foram São Carlos, Araraquara, Descalvado, Ribeirão Bonito e Dourado. Os municípios de Monte Alto, Candido Rodrigues, Taquaritinga, Tabatinga, Santa Lucia, Américo Brasiliense, Boa Esperança do Sul e Trabiju apresentaram áreas de vulnerabilidade muito baixa a média. A utilização de modelo de áreas vulneráveis a ataques de D. rotundus a bovinos utilizando análise multicritério em SIG fornecem elementos que podem ajudar a delinear estratégias de gestão ao combate e prevenção a ocorrência da raiva bovina em rebanhos, permitindo otimizar tempo e recursos.
