Drought is the most complex but least understood of all natural hazards. It is broadly defined as \“severe water shortage”. Floods cause huge but mainly material damages. Mentioned natural hazards cause loss of life, human and animal suffering and damage to economy and environment. The present study area is prone to extreme climate events such as drought and flood. The objective of this study was to investigate precipitation trends in the chosen climatic stations in Libya and Slovakia. Annual and monthly precipitation trends were detected by the Mann-Kendall statistical test. Significant negative trends of annual precipitation were found in four out of seventeen analyzed rainfall gauging stations in Libya. Significant positive trends of annual precipitation were found in six out of twenty analyzed rainfall gauging stations in Slovakia. November and August were observed to have decreasing trends in Libya and March in Slovakia. All other months displayed increasing trends in precipitation. The results show a trend towards drier conditions in Libya and an increase of moisture in Slovakia. Keywords: precipitation, trend, Mann-Kendall statistical test, drought, flood.
