THE IMPACT OF WAR ON ECONOMIC ACTIVITY IN UKRAINE USING SATELLITE NIGHT LIGHT DATA TO ASSESS THE ECONOMIC SITUATION

This study examines the impact of war on economic activity in Ukraine through the analysis of satellite Night Light data. Traditional economic indicators, such as Gross Regional Product (GRP), are not always available in conflict areas, making it difficult to assess the actual state of the economy. The use of satellite data provides objective and timely information on the level of economic activity, particularly in regions most affected by military actions. The study analyzes the correlation between Night Light intensity and economic indicators and extrapolates GRP for 2022-2023. The results show a significant decline in economic activity in areas of active military conflict and occupied territories, confirming the effectiveness of satellite data for economic monitoring. Keywords: satellite data, night lights, economic activity, regression models, regional development, economic monitoring.
