The purpose of this paper is to analyse and assess the extent of drought, being of particular importance
for plants. The area of study is applied to the region of Saxony-Anhalt between 1951 and 2015. The
methods of analysis being implemented are various drought indices, especially the ‘Klimafeuchtezahl’
(KFZ). It can be broken down into three main results. In terms of annual levels, there is no distinct direction
showing developing tendency of drought. Concerning the first vegetation period (April - June),
there is a clear development in the increasing tendency of drought, whereas during the second vegetation
period (July - September) there is often a decrease of meteorological drought and an increase of agricultural
drought. The results notably show that the agricultural drought - having the most significance
for plants - increased. As a closing remark, it is relevant for Saxony-Anhalt, and its strong connection
to agriculture, to adapt the kinds of crops and trees to increasingly dry conditions as well as to diseases
and insects of drought, and to control the type of irrigation and soil cultivation. Equally important is
the ability to recognise the advantages of the shifting circumstances: e.g. the increasing tillable area of
several crops (e.g. grapevines).
