Results of space multispectral images (LandSat and Quickbird) and ArcGIS using for monitoring of Environmental changes (like coastlines mapping) and hazardous events (like fire traces) in Ukraine in the framework of some National projects and the FP7 PERSEUS project are presented. Odessa National I.I. Mechnikov University case studies of coastline long‐term dynamics in the North‐Western Black Sea (NWBS) for 1983‐2013, as well as annual fire traces mapping in the Lower Dniester Delta in 2007‐2013 are described. Assessment of the long‐term coastline dynamics caused by abrasion and accumulation processes in the NWBS under the influence of natural and anthropogenic factors for the past 30 years is discussed. It is shown that that processes intensity could be various in different NWBS areas depending on geological structure and lithological composition of the exposed material on coastal cliffs; on intensity and direction of waves and currents; composition, direction and rate of sediments flow; and human activities. It has been concluded that maximal coastline changes took place in river deltas (the Danube, the Dniester, the Dnieper): in 1983‐2013 more than 16 sq. km. growth of land was observed and decrease of dry land in other parts made about 5 sq. km. Second case study presented the results of digitizing of fire traces in the Dniester river delta using Landsat images and ArcGIS. It was shown that every year from 1000 up to 5000 ha (4‐20 % of the Dniester delta square) could be covered with fire traces. Annual fire traces monitoring is also enabling us to locate the places in which fires occur year by year. Future possible application of RS/GIS for other environmental tasks in the Black Sea region has been discussed, especially for the deltaic areas and in the area of the city of Odessa, where natural and anthropogenic impact is very strong.
