To study the adaptive capacity of crop production under changing climatic conditions, a database of spatiotemporal characteristics of hazardous and adverse natural-climatic events during the warm season has created at the Laboratory of Geoecology and Geosystem Dynamics at the Institute of Monitoring of Climatic and Ecological Systems the Siberian Branch of the Russian Academy, for the southern taiga of Western Siberia. The components of the database, its structural features, and its capabilities of spatial assessment and cartographic visualization of the studied phenomena which it allows are shown. Based on the analysis of meteorological data from 32 stations over the last 20-year period, a series of thematic and integrated maps illustrating the territorial and temporal patterns of hazardous and adverse natural-climatic events have been created within a GIS environment. Intra-regional patterns in the intensity, frequency, and duration of these events were identified. Statistical assessment and mapping have revealed that climate-induced risks to the local crop production system are not decreasing and that their spatiotemporal patterns are heterogeneous. The highest risks for plant growing occur during the spring season and are associated with the hazardous phenomenon of late spring frosts. During the summer, climatic hazards in the northeast of the region are associated with intensive precipitation, while in the southwestern they are caused by hot weather. It has been noted that adverse events occur more frequently than hazardous ones and, in combination, create a high risk-forming potential. A detailed analysis of the spatiotemporal characteristics of the studied phenomena and the cartographic visualization of the results enable monitoring of developing hazardous situations, risk forecasting, and the formulation of recommendations for minimizing losses in crop production.
