This paper aims at estimation of the impact of climate change on future losses caused by uvial oods in Poland over the XXI century at the local level with the productivity costs valuation method. using the daily data on river discharges published by Piniewski et al. (2017), map of ood risk and value added generated in each county to produce county-level estimates of the impact of climate change on the uvial ood damage. Even though there is some research published by Al eri et al. (2016) or Feyen et al. (2012), their papers value the costs of future oods using the reconstruction cost method. This study aims to supplement their ndings with estimates of future ood losses in Poland using the productivity costs valuation that considers also the costs of disruptions of production chains and lost production in given areas. This method shows the overall increase in losses caused by uvial oods in Poland due to climate change in comparison to the reference period of 1974-2000 by 47% in RCP4.5 and 83% in RCP8.
