Abstract

Drought is a pervasive natural hazard, which can profoundly affect ecosystems and societies globally. To strengthen the global community’s resilience to droughts, a multi-dimensional understanding of global drought awareness is imperative. Here we investigate global drought awareness at local (awareness of local droughts in the affected country), remote (awareness of remote droughts in other countries), and global levels (awareness from non-exposed countries). This study uses relevant search activity volumes of a country to drought as a proxy of national-level drought awareness. We find that the recent decade has experienced no change in drought hazard over the globe, but the global community has been increasingly seeking information about drought online, that is, elevated awareness of the global community on drought. We further find that long-lasting droughts enhance local- and global-level awareness and high gross domestic product are associated with remote-level awareness. This study provides an observational evidence of global disparities in the awareness/interest regarding drought, underscoring a continuing role of European nations in enhancing global drought awareness.

全球干旱危害与认识之间的差距

干旱是一种普遍存在的自然灾害，可对全球生态系统和社会产生深远影响。为了加强全球社会抵御干旱的能力，必须从多维度了解全球干旱意识。在此，我们从本地（对受影响国家本地干旱的认识）、远程（对其他国家远程干旱的认识）和全球（非受影响国家的认识）三个层面对全球干旱认识进行了调查。本研究使用一个国家对干旱的相关搜索活动量来代表国家层面的干旱意识。我们发现，近十年来全球范围内的干旱危害没有发生变化，但全球社会却越来越多地在网上寻求有关干旱的信息，即全球社会对干旱的认识有所提高。我们进一步发现，持续时间长的干旱提高了地方和全球层面的意识，而高国内生产总值则与远程层面的意识相关。这项研究为全球对干旱的认识/兴趣差异提供了观察证据，强调了欧洲国家在提高全球干旱意识方面的持续作用。
