20.500.12556/RUL-189517 A systematic approach to the comprehensive assessment of environmental risks of soil degradation in the Ukrainian Forest-Steppe Sistematični pristop k celoviti oceni okoljskih tveganj degradacije tal v ukrajinski gozdni stepi This article investigates soil degradation risks in the Ukrainian Forest-Steppe driven by climate change and agricultural intensification. The study develops and validate the Integrated Index of Environmental Risk (IIER) for a comprehensive assessment and mapping of agroecosystem stability. The methodology employs a systemic approach and additive modeling of three components: climatic exposure, anthropogenic pressure (arable land share, erosion), and soil vulnerability (humus content and NPK balance). Analysis over recent decades reveals that a 1.2 °C increase in average annual temperature leads to aridification in the eastern Forest-Steppe and moisture instability in the west. Critical land cultivation (80.8 %) causes erosion to 27.5 % of the area. A progressive decline in soil organic matter (with an average humus content of 3.20 %) and a significant macronutrient deficiency (36–72 % of optimal levels) were recorded. The developed IIER framework enabled the identification of critical degradation zones in the Kharkiv, Poltava, and Cherkasy regions, where the synergy of natural and anthropogenic factors threatens the irreversible loss of soil fertility. This methodological approach serves as a predictive tool for identifying unstable agroecosystem components and substantiating regenerative agriculture. environmental risk soil degradation Integrated Index of Environmental Risk (IIER) induced systemic resistance (ISR) climate change agroecological indicators regenerative agriculture okoljsko tveganje degradacija tal integrirani indeks okoljskega tveganja (IIER) podnebne spremembe agroekološki kazalniki regenerativno kmetijstvo true false true Angleški jezik Slovenski jezik Članek v reviji 2026-10-08 11:07:56 2026-10-08 11:08:02 2026-10-10 03:49:21 0000-00-00 00:00:00 2026 0 0 12 str. no. 3 Vol. 122 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 631 1854-1941 10.14720/aas.2026.122.3.27328 294221315 LISHCHUK++et+al.+(G).pdf LISHCHUK++et+al.+(G).pdf 1 2E1FD52A84D7B8B3849FAD530C7DD819 3867a1d10b08da7116251ddc1109921b8cfbcbdf25f0eb76472655f0ee75c938 b1de9e43-c2f7-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=250130 https://journals.uni-lj.si/aas/article/view/27328/22599 1 9e632386-c2f7-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=250129 Biotehniška fakulteta Acta agriculturae Slovenica Acta agriculturae Slovenica 0 0 0
