During the period between 1961-2014, for which observed data were available from the we noted trend to increased drought occurrence at most stations. These tendencies were followed also by increase in the number of tropical days and decrease of the snow cover duration. Presented projections of climate change in the Czech Republic were shown to indicate the risk of prolonged and intense drought episodes and marked increase in the number of days that could be characterized as extremely dry. This would have a major impact on the sector of agriculture, forestry and water management. It would adversely influence the stability of agricultural production, wood increments and river flows and thus water provisioning. With higher extremity of the drought episodes (and its apparent coupling with increased number of tropical days) it is very likely that occurrence of extreme impacts (e.g. large and significant declines in agricultural and forest production, extensive forest fires or regional scarcity of water resources) might become a reality. It should be noted that in recent decades, these phenomena in the country (in relation to drought) did occurred or only in a fairly limited extent.
