Objective: Humidity and temperature are fundamental for the balance in the life cycle of living beings and, consequently, for maintaining the well-being of the human population and reducing the prevalence of infectious diseases. Thus, in order to mitigate the impact of climate change, especially in the period when humidity is not the ideal, it is necessary to adopt some assistance measures. The present experimental study aims to elucidate what would be the recommended option to improve the quality of life of the human being and to clarify which resources (air humidifier, bucket of water or wet towel) will be effective to improve the humidity of the air in times of drought and low moisture. Methods: The experimental study was carried out with INKBIRD hygrometers allowing the analysis of the variation of air humidity throughout the day. Three forms of treatment were established: humidifier, wet towel and bucket of water. In each room, two hygrometers were placed equidistant from the occupant of the room and their respective treatment that varied between 1m and 2m away from the headboard indoor each room. In addition, two environments were used as controls, one being an external environment and the other an internal closed environment, totaling five rooms for the study. The rooms were monitored between the end of July and the end of August 2019 in Goiania (GO). Results: Although assistance measures are used to significantly improve air pollution in times of extreme drought, there was a significant difference between them. The humidifier and a wet towel had 7.50% and 5.71% more humidity in the external relation (external control), respectively, more efficient. The volume of water, however, did not show significant difference (p>0.05) and, therefore, there was no variation. Conclusion:The humidifier and the towel are treatments considered more efficient, and that there was a significant effect of distance on humidity. Therefore, 1m of distance is more efficient in increasing and/or maintaining air humidity, inducing improvements in the populations' health.

Em estudos com fitofisionomias do Bioma Cerrado, as florestas estacionais estiveram entre as formações com maior carência de estudo. Apesar do aumento expressivo de pesquisas nos últimos anos, elas se concentram em estados do sul e sudeste brasileiro; já em boa parte do Cerrado nordestino, ainda há muitas lacunas no conhecimento dos processos ecológicos que as envolvem. Este artigo tem como objetivo suprir parte dessa deficiência ao descrever a estrutura espacial e a dinâmica da cobertura vegetal de duas florestas estacionais. Ao longo da paisagem regional, essas fitofisionomias, em que estão restritas a eixos de drenagem próximos às vertentes dos chapadões dominantes na região. Para a avaliação espaço-estrutural das duas fitofisionomias, foram elaborados diagramas de perfis de vegetação e análise florística, já a dinâmica temporal foi observada através do cálculo do Índice de Área Foliar (LAI) das estações chuvosa e seca usando como referência imagens de satélite. Averiguou-se que as florestas estudadas possuem características estruturais e florísticas diferenciadas, as quais têm papel fundamental na dinâmica temporal percebida pelo LAI, cujos índices são semelhantes na estação chuvosa, distinguindo-se significativamente na estação seca. Este estudo demonstra a importância dessas metodologias na definição de unidades da paisagem.
