Registration Date 08-01-2026 Organization Institute of Agroecology and Environmental Management of National Academy of Agricultural Sciences of Ukraine popup.description1 Determining the impact of the consequences of the explosion of the Kakhovska HPP on the state of agricultural resources in the Southern region based on satellite data popup.description2 It has been established that the disruption of irrigation systems due to the destruction of the Kakhovka Reservoir has intensified the negative consequences of climate warming, particularly increasing long-term risks of climate aridization for the region's agriculture. Almost the entire territory of Kherson Oblast and the southern coastal part of Zaporizhzhia Oblast have become zones with the highest frequency of drought phenomena. The territories along the Dnipro River in Kherson Oblast and the central part of Zaporizhzhia Oblast, which previously had irrigation from the Kakhovka Reservoir system, experienced low frequency of drought phenomena. However, this territory is now experiencing negative impacts due to the disruption of irrigation systems. The destruction of irrigation has led to deterioration of vegetation conditions, as measured by the NDVI index. Average NDVI values during the growing season in Kherson Oblast decreased by 20-30%, and in some years by half, indicating a significant reduction in plant biomass. In Zaporizhzhia Oblast, the decline of this indicator was somewhat less—15-20%, and in Dnipropetrovsk Oblast—up to 10%. The NDWI index revealed hydrological changes in vegetation conditions. In Kherson Oblast, average NDWI values after June 2023 decreased by more than half, indicating a significant reduction in plant moisture content and a critical level of water deficit. In Zaporizhzhia Oblast, the NDWI decline was 15-20%, while in Dnipropetrovsk Oblast the index values remained stable, meaning without negative changes. In the control territory—the "Askania-Nova" Biosphere Reserve—a moderate decrease in NDWI was observed, likely related to regional climate warming. Overall, as a result of climate warming and the absence of irrigation, a temporal decrease in moisture reserves in the one-meter soil layer is observed, which reduces the adaptive capacity of vegetation and agro-ecosystems as a whole to temperature stresses during the growing season.
