This community‐based research aims to enhance local‐level flood management by utilising participatory geographic information systems (PGIS) methods to capture the spatial dimensions of community member flooding concerns in Hopkins Village, Belize. We offer a mixed methodology, applying participatory sketch mapping as a way to collect local knowledge about community perceptions of flooding in this data‐scarce context. We combine this local knowledge with quantitative geostatistical hot spot analysis of basic village infrastructure characteristics to reveal insights about community perceptions of and response to flood risk. The significance of this research lies in the application of PGIS methods to create two different primary datasets, which when analysed together offer a more complete story about community understanding and needs for flood management. One set of data (more qualitative in nature) originated from sketch maps with community members and answers descriptive questions about how people spatially conceptualise hydro‐meteorological hazards within their community. The other (more quantitative in nature) is the village's first publicly accessible infrastructure dataset (including information on building structures, roads, and drainage infrastructure) digitised by our research team from high‐resolution drone imagery. Attributes for the infrastructure dataset were developed in collaboration with community members to reflect their desires for data and information suited to conduct flood vulnerability assessment. Application of thematic coding and hot spot analysis to the data reveals concerns about hazards within their community and the measures they have taken to protect themselves in the absence of resources to develop community‐wide mitigation plans. Our work offers contributions to the participatory GIS literature by providing an example of sketch mapping methods to facilitate multi‐level management of community‐level flood risk in a data‐scarce setting, and demonstrating the multiple benefits of applied participatory GIS methods as a means of overcoming data scarcity.

整合草图绘制和热点分析,以增强社区级洪水和灾害风险管理的能力

这项基于社区的研究旨在通过利用参与性地理信息系统(PGIS)方法来捕获伯利兹霍普金斯村社区成员洪水问题的空间维度,来增强地方一级的洪水管理。我们提供了一种混合方法,将参与式草图映射用作一种在这种数据稀缺的情况下收集有关社区对洪水的看法的本地知识的方法。我们将这些当地知识与基本村庄基础设施特征的定量地统计学热点分析相结合,以揭示有关社区对洪水风险的认识和对洪水风险的响应的见解。这项研究的意义在于应用PGIS方法创建两个不同的主要数据集,一起分析后,就可以更全面地了解社区对洪水管理的了解和需求。一组数据(本质上更具定性)源自与社区成员的示意图,回答了有关人们如何在空间上概念化社区内水文气象灾害的描述性问题。另一个(本质上更具定量性)是该村的第一个可公开访问的基础设施数据集(包括有关建筑结构,道路和排水基础设施的信息),该数据集由我们的研究团队从高分辨率的无人机图像进行了数字化处理。与社区成员合作开发了基础设施数据集的属性,以反映他们对适合进行洪水脆弱性评估的数据和信息的需求。对数据进行专题编码和热点分析后,人们就对社区内部的危害以及在缺乏资源来制定社区范围的缓解计划时采取的自我保护措施表示担忧。我们的工作为参与式GIS文献做出了贡献,提供了一个草图绘制方法的示例,以在数据稀缺的环境中促进社区级洪水风险的多级管理,并演示了应用参与式GIS方法作为多种手段的多重好处。克服数据短缺。
