Remote spatial analysis lacking ethnographic grounding mischaracterizes sustainability of Indigenous burning regime / Análise espacial remota sem embasamento etnográfico descaracteriza a sustentabilidade do regime de queimada indígena

Abstract: Scientific research that purports to evaluate Indigenous fire regimes in the absence of ethnographically contextualized ecological data runs the risk of exacerbating the fire blame game and providing evidence to support distorted narratives advanced by anti-Indigenous advocates. Spatial analysis of fire scars in Indigenous territories can be an effective tool for characterizing cultural fire regimes in terms of distribution and frequency, especially when qualified by linkages to different local ecosystems. A recently published article drew on fire scar mapping from satellite imagery to assess anthropogenic fire distribution and frequency in the Pimentel Barbosa Indigenous Land, Central Brazil. The authors use their findings to characterize A'uwẽ (Xavante) use of fire as unmanaged and a model of unsustainable use of cerrado resources. In this article, we discuss Aguiar & Martins's recent paper in light of our long-term research on A'uwẽ hunting with fire in the Pimentel Barbosa Indigenous Land, arguing that A'uwẽ hunters do burn according to established cultural protocols, manage their use of fire for conservationist purposes, and do not cause environmental degradation by burning.

Resumo: A pesquisa científica que pretende avaliar regimes indígenas de queimadas na ausência de dados ecológicos contextualizados etnograficamente corre o risco de exacerbar o jogo de culpabilização do fogo, fornecendo evidências para apoiar narrativas distorcidas apresentadas por militantes anti-indígenas. A análise espacial de cicatrizes de fogo em territórios indígenas pode ser uma ferramenta eficaz para caracterizar regimes culturais de fogo em termos de distribuição e frequência, especialmente quando qualificada por ligações a diferentes ecossistemas locais. Um artigo publicado recentemente se baseou no mapeamento de cicatrizes de fogo a partir de imagens de satélite para avaliar a distribuição e frequência antropogênica de fogo na Terra Indígena Pimentel Barbosa, Brasil Central. Os autores usam seus resultados para caracterizar o uso do fogo pelos A'uwẽ (Xavante) como não manejado e um modelo insustentável de uso de recursos do cerrado. Neste artigo, discutimos o artigo recente de Aguiar & Martins à luz de nossa pesquisa de longa duração sobre a caçada com fogo praticada pelos A'uwẽ na Terra Indígena Pimentel Barbosa, argumentando que os caçadores A'uwẽ queimam de acordo com protocolos culturais estabelecidos, manejam o fogo de maneira conservacionista e não causam degradação ambiental pela queimada.

Fire prevention management and practice of data room in hospital / 医疗卫生装备

Objective To explore the fire prevention management to ensure the operating of the data room in the hospital. Methods The hidden risks in the fire prevention of the data room were pointed out in auto fire fighting system,precision air-conditioning equipment, UPS and battery pack, compatibilization and expansion, high-voltage power supply circuit, lightningproof grounding and etc.It's indicated that the maintenance staff had deficiency in mastering related knowledge on gas fire-extinguishing system.Results The maintenance had to be strengthened for the auto fire fighting system,precision air-conditioning equipment,UPS and battery pack,and the detection should be reinforced for the high-voltage power supply circuit and lightningproof grounding system. It's suggested that standardized construction be executed during data room compatibilization and expansion,corresponding management system be established,and the knowledge be mastered on the composition,operation and announcements.Conclusion The fire prevention management of the data room is enhanced in the hospital,and the hidden risks are eliminated for fire fighting.
