The aim of the study was to attempt to estimate the demand for water for strawberry grown in the Chojnice county depending on expected climate changes. The study takes into account two scenarios (RCP 4.5 and RCP 8.5) for the period 2021-2100. It was found that in the reference period, the total rainfall deficits during the strawberry growing season in the Chojnice county - in the average, moderately dry and very dry years - amounted 31 mm, 127 mm and 192 mm, respectively. The largest monthly rainfall deficit during the strawberry growing season of the reference period occurred in June. The amount of rainfall deficit - in the average, moderately dry and very dry year - was on the level 19 mm, 39 mm and 53 mm, respectively. In the forecast period (2021-2100), the largest monthly rainfall deficits during the strawberry growing season will occur in July. These rainfall deficits under the RCP 4.5 scenario - in a medium, moderately dry and very dry year - will amount 15 mm, 40 mm and 58 mm, respectively. In the light of the RCP 8.5 scenario, rainfall deficits in July will be even higher and may amount to 17 mm, 43 mm ...
