Erfassung und Bewertung von Dürren in Sachsen-Anhalt (1951 – 2015) mittels verschiedener Indikatoren bzw. Parameter bezogen auf ausgewählte Anwendungsbereiche

Abstract

Maruschke, J.-M.: Analysis and assessment of drought in Saxony-Anhalt (1951 – 2015) by means ofvarious indices or parameters respectively related to selected fields of applications. - Hercynia N. F. 51/1(2018): 30 – 57.The purpose of this paper is to analyse and assess the extent of drought, being of particular importancefor plants. The area of study is applied to the region of Saxony-Anhalt between 1951 and 2015. Themethods 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 directionshowing 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 vegetationperiod (July - September) there is often a decrease of meteorological drought and an increase of agriculturaldrought. The results notably show that the agricultural drought - having the most significancefor plants - increased. As a closing remark, it is relevant for Saxony-Anhalt, and its strong connectionto agriculture, to adapt the kinds of crops and trees to increasingly dry conditions as well as to diseasesand insects of drought, and to control the type of irrigation and soil cultivation. Equally important isthe ability to recognise the advantages of the shifting circumstances: e.g. the increasing tillable area ofseveral crops (e.g. grapevines).
