The spread of the 2019 novel coronavirus disease (COVID-19) has engulfed the world with a rapid, unexpected, and far-reaching global crisis. In the study of COVID-19, Geographic Information Systems (GIS) and Remote Sensing (RS) have played an important role in many aspects, especially in the fight against COVID-19. This review summarises 102 scientific papers on applications of GIS and RS on studies of the COVID-19 pandemic. In this study, two themes of GIS and RS-related applications are grouped into the six categories of studies of the COVID-19 including spatio-temporal changes, WebGISbased mapping, the correlation between the COVID-19 and natural, socio-economic factors, and the environmental impacts. The findings of this study provide insight into how to apply new techniques (GIS and RS) to better understand, better manage the evolution of the COVID-19 pandemic and effectively assess its impacts.

Geographic Information System (GIS) and Remote Sensing (RS) techniques have been used increasingly for marine sheries development and management over the last years. However, its applications continue to be scarce in Colombia. This paper brie!y reviews use of spatial tools in marine sheries management, both retrospectively and predictively. Case studies of RS and GIS in sheries research in Colombia and challenges for future use for management measures are discussed. In order to harness the potential of GIS and RS tools in marine sheries research and management, priority should be given for training sheries scientists in RS and GIS, increasing collaboration among institutions, departments, standardize data collection, and development of a common platform for data sharing.

Suicide is an unfortunate multifactorial problem impacting families and communities. Many young lives are lost every year due to suicide. There is an urgent need to understand the multifactorial risk factor mechanisms providing vulnerability to suicidal behavior for early detection of impending incidents, monitoring, and prevention. This review aims to give an insight into the various biochemical and genetic markers along with the associated socio-economic factors and mental disorders which contribute to increased suicide risk. The role of different neurotransmitter-associated pathways such as serotonin, gamma aminobutyric acid (GABA), and norepinephrine pathway, and pathways involving the hypothalamic-pituitary-adrenal (HPA) axis, lipid metabolism, and neuroinflammation in suicide ideation and risk have been explored. Understanding of these predisposing factors and associated pathways could help identify the risk and lead to the development of drugs/ treatment to prevent suicides.

R E S U M O Este artigo tem como objetivo mapear o uso e ocupação do solo no município de Belém de São Francisco, localizado na mesorregião do São Francisco, Pernambuco, na porção semiárida do nordeste brasileiro. Foram utilizadas ferramentas de Sistemas de Informações Geográficas (SIGs) e técnicas de sensoriamento remoto. Foi realizada uma classificação não-supervisionada do uso e ocupação do solo, onde foi feita a identificação de quatro temas: corpos d’água, vegetação densa, vegetação rasteira e solo exposto/área urbana, nos diferentes anos de 1985 e 2010. As imagens utilizadas foram do sensor Landsat 5 TM, coletadas no acervo de imagens do INPE. Os mapas foram elaborados no software ArcGIS 10.1, utilizando o sistema de coordenadas Sirgas2000, no fuso 24S. Os resultados mostraram diferentes fases de uso e ocupação do solo, apresentando diferentes causas de sua variação espaço-temporal, incluindo mudanças nos recursos hídricos, na vegetação e consequentemente na ocupação urbana do município.    A B S T R A C T This article aims to map the use and occupation of land in the city of Bethlehem in San Francisco , located in the middle region of the San Francisco PE in semiarid northeastern part of Brazil . Geographic Information Systems ( GIS ) and remote sensing tools were used . Water bodies , dense vegetation , low vegetation and bare soil / urban area in different years 1985 and 2010 : methodology as a non - supervised classification of the use and occupation of land , where the identification of four themes was done was done. The images used were from Landsat 5 TM , collected in the collection of images from INPE . The maps were drawn with ArcGIS 10.1 software , using SIRGAS2000 coordinate system , the spindle 24S . The results showed different phases of use and occupation of land , with different causes of their spatio-temporal variation , including changes in water resources , vegetation and consequently the urban occupation of the city .Keywords: Use and land cover, remote sensing, geographic information system.

Abstract In the last decades, wildfire hazards have increased to dangerous levels, becoming the focus of debate among policymakers both at the local and national levels. This paper proposes a Spatio-temporal approach to study the determinants of fire size distributions taking Sardinia as a case study in the time span 1998-2009. Special attention is devoted to socioeconomic factors of local communities where wildfires occurred. The main finding of this study is that the proportion of public lands in a given municipality tends to mitigate the extent of the burned area. In addition, communities with a higher percentage of people employed in the primary sector are less likely to experience large burned extents.
