Since the 19th century, the Czech Republic's irrigation industry has undergone significant technological development and expansion. However, political changes and neglect led to the deterioration of irrigation systems and buildings. Recently, there has been a renewed focus on irrigation due to climate change and the increasing threat of drought. A database of irrigation systems is currently being compiled, and historic structures are being documented using unmanned aerial vehicles.
Since the 19th century, the irrigation industry on the territory of the Czech Republic has undergone considerable technological development and an increase in irrigated areas. Irrigation has become an important part of the Czech landscape. Large complex irrigation systems of tens to hundreds of km2 have been built. Towards the end of the 20th century, there was a significant decline due to the change of political regime, abolition of agricultural com- panies, etc. Irrigation systems and buildings were often destroyed, devastated, left without maintenance. There have also been several changes in the administrative management of the irrigation sector. The consequence was that there was no single database of irrigation systems. At present, a database of these irrigation systems is being compiled by the Research Institute for Soil and Water Conservation using geographical information systems (GIS). In connection with climate change, the threat of drought, and irregular distribution of precipitation during the growing season, and the issue of irrigation are back on trend. In this study the current state of irrigation systems in the Czech Republic was presented. In the Czech Republic, a total of 175115 ha of irrigation area has been recorded so far (of this area, about 41% is currently in functional). Selected historic irrigation structures were documented by unmanned aerial vehicles (UAV).
