Cartografia bibliométrica da vulnerabilidade climática de culturas baseada em sensoriamento remoto: do monitoramento espectral à inteligência geoespacial preditiva
Conteúdo do artigo principal
Resumo
A intensificação de secas, ondas de calor e inundações está ampliando a vulnerabilidade das culturas e comprometendo a segurança alimentar, o que exige uma base científica robusta para orientar a adaptação agrícola com apoio do sensoriamento remoto. Este estudo teve como objetivo descrever e analisar quantitativamente a evolução da pesquisa sobre vulnerabilidade climática de cultivos baseada em sensoriamento remoto, identificando padrões temporais, geográficos e temáticos. Aplicou-se um desenho bibliométrico quantitativo, exploratório, descritivo, longitudinal e retrospectivo a 2.343 registros da Scopus publicados entre 1985 e 2026, processados no Bibliometrix 5.1.1 e no VOSviewer 1.6.20 com indicadores de produtividade, impacto e colaboração, juntamente com RPYS. Os resultados mostram crescimento anual de 4%, 627 fontes, 10.408 autores, 5,17 coautores por documento, 35,3% de colaboração internacional e 19,93 citações por documento, com liderança de China, Estados Unidos e Índia. Remote Sensing e Science of the Total Environment concentraram a difusão, enquanto machine learning e Google Earth Engine marcaram a agenda recente. Conclui-se que o campo alcançou maturidade científica e tecnológica, consolidou o sensoriamento remoto como eixo estratégico para avaliar, modelar e antecipar a vulnerabilidade agrícola, e avançou para abordagens preditivas com alta relevância para a adaptação às mudanças climáticas.
