Researchers across disciplines have long sought to collect ‘perishable data’ in the context of disasters. Yet, this data type is neither consistently defined nor discussed in specific detail in the literature. To address this gap, this paper defines perishable data and provides guidance on ways to improve both how it is collected and shared. Here, perishable data is conceptualised as highly transient data that may degrade in quality, be irrevocably altered, or be permanently lost if not gathered soon after it is generated. Perishable data may include ephemeral information that must be collected to characterise pre-existing hazardous conditions, near-miss events, actual disasters, and longer-term recovery processes. This data may need to be gathered at multiple points in time across varying geographic scales to accurately characterise exposure, susceptibility to harm, or coping capacity. The paper considers ethical and logistical challenges and discusses opportunities to advance equitable perishable data collection and dissemination.

定义、收集和共享易腐烂的灾害数据

跨学科的研究人员长期以来一直寻求在灾难背景下收集“易腐烂的数据”。然而，这种数据类型在文献中既没有一致的定义，也没有具体详细的讨论。为了解决这一差距，本文定义了易腐烂的数据，并就如何改进数据的收集和共享方式提供了指导。在这里，易腐烂的数据被概念化为高度瞬态的数据，如果在生成后不立即收集，这些数据可能会质量下降、被不可挽回地更改或永久丢失。易腐烂的数据可能包括必须收集的临时信息，以描述预先存在的危险状况、未遂事件、实际灾难和长期恢复过程。这些数据可能需要在不同地理范围的多个时间点收集，以准确描述暴露程度、伤害易感性或应对能力。本文考虑了道德和后勤方面的挑战，并讨论了促进公平易腐数据收集和传播的机会。
