Sažetak
The main goal of this paper was to indicate the intensity and trend of climate changes in Virovitica-Podravina and Lika-Senj Counties (hilly and mountain area) by comparing basic meteorological data from the first climate period (1981-2000) with data from the second climate period (2001-2020), and determine the impact of climate change on soil water deficit for the most common crops such as cabbage, potatoes and maize. In the Virovitica- Podravina County, a trend of an increase in the average annual precipitation by 87.9 mm and air temperature by 1.0 ºC was recorded in the period 2001-2020. in relation to the period 1981-2000. A similar trend was recorded in the vegetation period (IV-IX), with higher precipitation (by 56.2 mm) and higher air temperature (by 0.9 °C) in the second period compared to the first. In the Lika-Senj County, the average annual precipitation was 27.8 mm higher, and the air temperature was 1.2 ºC higher in the second period compared to the first. However, in the vegetation period, the amount of precipitation in the second climate period was 27.2 mm lower, and the air temperature was 1.2 ºC higher compared to the first period. The biggest difference in the soil water deficit in the Virovitica - Podravina County between the two periods with regard to the long-term average of precipitation was determined for cabbage (57.3 mm), and the smallest for maize (48.0 mm), while in dry years, this difference was the largest for cabbage (118.3 mm), and the smallest for corn (101.2 mm). In the Lika-Senj County, the largest difference in soil water deficit between two periods in the multi-year average precipitation was determined for potatoes (27.1 mm), and the smallest for cabbage (15.1 mm), while in dry years this difference was the largest for potatoes (43.1 mm), and the smallest for cabbage (37.8 mm). Changes in the climate in this Counties are the reason for a significant increase in the soil water deficit for corn, potatoes and cabbage, both in the multi-year average and in dry years. In order to compensate for the soil water deficit and achieve efficient agricultural production, it is necessary to plan the design and construction of irrigation systems in the areas of both Counties.
