This study examines the convergence between traditional and scientific knowledge regarding the use of fire and its potential to trigger wildfires, with possible impacts on ecosystems and human well-being. The research encompasses three distinct natural regions of Ecuador: the coast, the highlands, and the Amazon. Data on traditional fire use were collected through semi-structured interviews with 791 members from five local communities. These data were compared with climatic variables (rainfall (mm), relative humidity (%), wind speed (km/h), and wind direction) to understand the climatic conditions conducive to wildfires and their relationship with human perceptions. Furthermore, the severity of fires over the past 4 years (2019-2022) was assessed using remote sensing methods, employing the Normalized Burn Ratio (NBR) and the difference between pre-fire and post-fire conditions (NBR Pre-fire-NBR Post-fire). The results revealed a significant alignment between traditional knowledge, climatic data, and many fires, which were of low severity, suggesting potential benefits for ecosystems. These findings not only enable the identification of optimal techniques and timing for traditional burns but also contribute to human well-being by maintaining a harmonious balance between communities and their environment. Additionally, they provide valuable insights for the development of more inclusive and effective integrated fire management strategies in these natural areas of Ecuador.
本研究考察了传统知识与科学知识在火的使用及其引发野火的潜力方面的趋同,以及这可能对生态系统和人类福祉产生的影响。该研究涵盖了厄瓜多尔的三个不同自然区域:沿海地区、高地和亚马逊地区。通过对来自五个当地社区的 791 名成员进行半结构化访谈,收集了有关传统火的使用的数据。这些数据与气候变量(降雨量(毫米)、相对湿度(%)、风速(公里/小时)和风向)进行了比较,以了解有利于野火发生的气候条件及其与人类认知的关系。此外,还使用遥感方法评估了过去 4 年(2019-2022 年)的火灾严重程度,使用归一化燃烧比(NBR)和火灾前后的差异(NBR 前火-NBR 后火)来评估。结果表明,传统知识、气候数据和许多低严重程度的火灾之间存在显著的一致性,这表明对生态系统可能有益。这些发现不仅可以确定传统燃烧的最佳技术和时机,还可以通过维持社区与其环境之间的和谐平衡,促进人类福祉。此外,它们还为在厄瓜多尔这些自然地区制定更具包容性和有效的综合火灾管理战略提供了有价值的见解。
