Abstract

Climate change on the globe has been manifested over the past few decades by, among other things, an increase in the frequency of extreme weather events, such as droughts. Drought affects millions of people around the world every year. Its effects usually appear after a long period of rainfall deficit. Based on climate projections, it is emphasized that water scarcity will be one of the most important problems in the future. Due to the importance of the increasing problem of drought, the analysis of this phenomenon in Poland was undertaken in the context of agriculture. The aim of this study was to assess the course of drought in the vegetation period during years 2001-2020 for Poland based on the Selyaninov’s coefficient (HTC). As shown in this study, the western and central parts of the country, dominated by arable land, are particularly vulnerable to drought. Due to the cyclic nature of periods classified by HTC as dry, it can be concluded that the problem of precipitation deficit for crops in Poland could get worse.

基于水热系数的波兰塞利亚尼诺夫地区农业干旱评价
在过去几十年里,全球气候变化的表现之一是极端天气事件(如干旱)的频率增加。干旱每年影响着全世界数百万人。它的影响通常出现在长时间的降雨不足之后。根据气候预测,强调水资源短缺将是未来最重要的问题之一。由于日益严重的干旱问题的重要性,对波兰这一现象的分析是在农业的背景下进行的。本研究的目的是基于Selyaninov系数(HTC)评估波兰2001-2020年植被期的干旱过程。如本研究所示,该国以可耕地为主的西部和中部地区特别容易受到干旱的影响。由于HTC归类为干旱的周期的周期性,可以得出结论,波兰作物降水不足的问题可能会变得更糟。
