Ao longo dos anos os três termos foram empregados de forma redundante e sobreposta, mesmo refletindo conjunturas ambientais distintas, com critérios diagnósticos diferentes. Ademais, mesmo com a participação crescente de pesquisadores brasileiros em trabalhos na Antártica, as discussões epistemológicas acerca desses ambientes ainda constituem lacuna nas publicações nacionais. A paisagem proglacial corresponde à área pioneira em receber os produtos da glaciação e este se revela um ambiente prioritariamente deposicional. É um ambiente complexo totalmente ajustado aos processos fluviais, lacustres e marinhos que ocorrem imediatamente adjacente ao glaciar e consequentemente o domínio proglacial acompanha a movimentação da margem do gelo. A paisagem paraglacial não é definida nem por processos nem pela localização, mas sim pela trajetória de reajustes da paisagem, adotando o critério tempo. Dessa forma, a paisagem paraglacial está em processo de transição, recuperando-se dos distúrbios da glaciação. Por fim, a paisagem periglacial é aquela com atuação de ciclos de congelamento e descongelamento (frost action) e congelamento sazonal do terreno, podendo possuir ou não permafrost.The paper proposes a discussion about origin and evolution of proglacial, paraglacial and periglacial concepts. It aims to show diff erentiation of landforms, process, questions and also the critiques that are unique of each other. Over the years the three terms have been made redundant and employed in an overlapping manner, even that they are quite diff erent concepts and are defi ned in quite diff erent ways. Furthermore, in spite of the growing participation of Brazilian researchers in Antarctica the epistemological issues about these environments still remains as a gap in national publications. The proglacial landscape is pioneer in receiving the glaciated products and it is a primarily depositional environment. Such environments are totally adjusted to the regime of fl uvial, marine and lacustrine processes that occur immediately adjacent to the glacier and consequently the proglacial domain follows the movement of the ice margin. The paraglacial landscape it is not defi ned by location or processes, but by trajectory from glacial to non-glacial environment. Thus, the diagnostic criteria is time, and the paraglacial environment is in recovering from the disturbance of glaciation. The periglacial realm is defi ned primarily by freeze-thaw cycles and deep seasonal freezing. The presence of permafrost is not required.CNPq - Conselho Nacional de Desenvolvimento Científico e TecnológicoFAPEMIG - Fundação de Amparo à Pesquisa do Estado de Minas GeraisCAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorporUniversidade Federal de Minas GeraisUFMGBrasilIGC - DEPARTAMENTO DE GEOGRAFIARevista Brasileira de GeomorfologiaAntártida - Descobertas e exploraçõesExpedições científicas - Regiões polaresMudanças ClimáticasGeleirasAntárticaPaisagens PolaresGeleirasMudanças ClimáticasPaisagens polares não glaciais (proglacial, paraglacial e periglacial): revisão de conceitos e contribuições da pesquisa pedogeomorfológica brasileiraNon-glaciated polar landscape (proglacial, paraglacial and periglacial): review of concepts and contributions of soil-geomorphology brazilian researchinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://rbgeomorfologia.org.br/rbg/article/view/1639Mariana de Rezende MachadoFábio Soares de OliveiraCarlos Ernesto g. r.
