直到最近，EM-DAT中记录的干旱事件并不一致。问题包括开始和结束日期的确定不一致，损失的错误归属，以及处理多年和多国事件的困难，主要是由于干旱发生缓慢、空间广泛、持续时间长和复杂的性质造成的。本文综述了1900 ~ 2004年807个干旱条目和76个饥荒条目的综合审查程序和结果。已经制定了一种标准化的方法来描述干旱事件的特征，该方法与数据库中记录的所有其他自然灾害相一致。其结果是，干旱次数比原来减少56%，死亡人数增加20%，经济损失增加35%。根据修订后的数据，与自然灾害有关的所有死亡中，有一半以上现在被归类为与干旱有关，在受影响人数方面，只有洪水排名更高。
Until recently, drought events were inconsistently recorded in EM-DAT. Problems included inconsistent establishment of start and end dates, misattribution of losses, and difficulties with handling multiyear and multicountry events, mostly arising from the slow onset, spatially extensive, prolonged, and complex nature of drought. This article summarizes the procedures and results of a comprehensive review of 807 drought and 76 famine entries from 1900 to 2004. A standardized methodology has been developed for characterizing drought events that is consistent with all other natural hazards recorded in the database. The result consists in a reduction of 56% from the original number of drought entries, a 20% increase in the number of deaths and a 35% increase in economic losses. Based on the revised data, more than half of all deaths associated with natural hazards are now classified as drought related, and only floods rank higher in terms of the number of people affected.
