May and June 2018 have brought serious anomalies in spring crops development in the European part of Russia and southern regions of West Siberia that are analyzed in this paper. It is shown that a considerable number of croplands with spring crops have more than 15 % worse NDVI compared to the «normal» (long-time average annual) by the end of week 24 of 2018 (June 17). During the season, in the European areas of Russia spring crops have slightly deteriorated, in contrast to West Siberia (e.g. the Altai Territory) where they have slightly improved. The causes of the phenomena observed are different for the different regions. The European part of Russia suffered from poor precipitation and lack of water which caused NDVI decline. An example of such scenario is shown for the Republic of Crimea and Volgograd region: dynamics of NDVI, cumulative precipitation and temperature for spring croplands are depicted. The worst situation is observed in the Republic of Crimea. The current state tends to show spring crops bad condition, expected reduction of yields and possible partial crop failure. The situation for the south-eastern regions of West Siberia is determined by other causes, shown by the examples of Novosibirsk Region and Altai Territory. In these regions, the anomaly is caused by spring crops development delay due to late sowing following heavy precipitation, significantly heavier than the long-time average annual, during the past months. It is noted that the development delays of the spring crops may not affect the expected yields and crop failure probability. In summary, it is emphasized that crops development deviation from “normal” dynamics can have different causes and consequences in different regions and thorough analysis of both remote sensing and meteorological data for the region is required for correct estimation of current state and potential impact. It is demonstrated that such analysis can be conducted using the Vega-Science (http://sci-vega.ru/) information system.
