Since 1964, maps showing areas of drought declaration in Queensland, Australia were created or updated as drought declarations changed. Prior to 1964, drought declarations were based on railway lines rather than specific areas. By using a railway distance buffer, drought declaration areas based on local government areas could be mapped. A literature review of the history of Queensland drought declarations, enabled mapping of the extent and duration of drought declarations for the period 1936–1964. Analysis of the changes in these areas enabled the duration of each drought episode to be determined. These data and information were then combined with the mapped drought declarations areas (1964–2020) to enable an assessment of drought area and duration in Queensland since 1936. There were 13 drought episodes of differing durations. Calculating the area percentage of Queensland that was drought declared from 1936 to the present (2020) identified an increasing duration of drought declaration. This increase appears to be due to the changes in the administration process to remove a drought declaration area (revocation) which have occurred since 1982.

自1964年以来，随着干旱声明的更改，创建或更新了显示澳大利亚昆士兰州干旱声明区域的地图。1964年之前，干旱声明是基于铁路线而不是特定地区的。通过使用铁路距离缓冲区，可以绘制基于地方政府区域的干旱申报区域。对昆士兰州干旱声明历史的文献回顾，使得能够绘制1936年至1964年干​​旱声明的程度和持续时间的图。通过对这些地区变化的分析，可以确定每次干旱发生的持续时间。然后将这些数据和信息与绘制的干旱宣布地区（1964-2020年）相结合，以评估自1936年以来昆士兰州的干旱地区和持续时间。共有13次不同持续时间的干旱事件。计算昆士兰州从1936年到现在（2020年）已宣布干旱的面积百分比，可以确定增加的干旱持续时间。这种增加似乎是由于自1982年以来取消干旱宣布区（撤销）的行政程序发生了变化。
