Resumo: | The relationship between specific pedogenic processes with soil vulnerability to degradation in the Northeastern semiarid region of Brazil is not yet well understood. This relationship is important duo to the possibility of subsidizing interventions and public policies in agreement with local specificities, which may contribute to mitigate and/or reverse the current situation of soil degradation. The aim of this study was to evaluate the relationship between specific pedogenic processes and soil vulnerability to land degradation and/or desertification in the microregions of Seridó and Cariri, located in Rio Grande do Norte and Paraíba states, respectively. Soil classes of these areas were identified by overlaying updated soil maps based on previous soil survey reports on heavily degraded areas. These areas are mainly associated with Abruptic Luvisol (Clayic) and Dystric Regosol (Locamic) in the Seridó and Haplic Luvisol (Clayic) and Eutric Regosol (Loamic) in the Cariri. Abrupt textural difference increases the vulnerability of Luvisols and Planosols to erosive processes. The anthrossolization can accelerate erosion, salinization, sodification, and solodization, causing soil loss, reducing soil physical quality, and siltation of water bodies. The relationship between specifics pedogenetic processes and land degradation can be better understood by assessing soils at higher categorical levels (subgroup). |

Esse entendimento pode subsidiar intervenções e políticas públicas que atenuem e/ou revertam à degradação dos solos. O objetivo dessa pesquisa foi avaliar a relação entre processos pedogenéticos específicos e a susceptibilidade dos solos a degradação/desertificação nas microrregiões do Seridó e Cariri. Foram atualizadas as classes de solos das unidades de mapeamento (UM) dos estados da Paraíba e Rio Grande do Norte. Essas novas UM foram sobrepostas com áreas fortemente degradadas (AFD). Áreas degradadas estão predominantemente associadas com Luvissolos Háplicos Pálicos abrúpticos e Neossolos Litólicos Eutróficos típicos e fragmentários no Seridó e com Luvissolos Crômicos Órticos típicos e vertissólicos no Cariri. O predomínio da agropecuária na maioria das AFD confirma a forte pressão antrópica sobre o meio ambiente. A mudança textural abrupta aumenta a susceptibilidade dos Luvissolos e Planossolos à degradação. Antrossolização pode acelerar a erosão, salinização, sodificação e solodização. Como consequência tem-se perdas de solos, de sua qualidade física e assoreamento de corpos hídricos. As relações entre processos pedogenéticos e degradação das terras são compreendidas com a avaliação dos solos em níveis categóricos mais elevados (subgrupo).EDUFU - Editora da Universidade Federal de Uberlândia2021-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/5539710.14393/RCG228155397Caminhos de Geografia; Vol. 22 No. 81 (2021): Junho; 176-195Caminhos de Geografia; Vol. 22 Núm. 81 (2021): Junho; 176-195Caminhos de Geografia; v. 22 n. 81 (2021): Junho; 176-1951678-6343reponame:Caminhos de Geografiainstname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/55397/31704Copyright (c) 2021 Rodrigo Santana Macedo, Raphael Moreira Beirigo, Beatriz Macêdo Medeiros, Victor Junior Lima Felix, Renato Francisco da Silva Souza, Alexandre Pereira de Bakkerinfo:eu-repo/semantics/openAccessMacedo, Rodrigo SantanaBeirigo, Raphael MoreiraMedeiros, Beatriz MacêdoFelix, Victor Junior Lima Souza, Renato Francisco da Silva Bakker, Alexandre Pereira de2021-06-02T16:45:52Zoai:ojs.www.seer.ufu.br:article/55397Revistahttps://seer.ufu.br/index.php/caminhosdegeografia/indexPUBhttp://www.seer.ufu.br/index.php/caminhosdegeografia/oaiflaviasantosgeo@gmail.com1678-63431678-6343opendoar:2021-06-02T16:45:52Caminhos de Geografia - Universidade Federal de Uberlândia (UFU)false |
