Explore historical and projected climate data, climate data by sector, impacts, key vulnerabilities and what adaptation measures are being taken. Explore the overview for a general context of how climate change is affecting Romania.

Impacts Water

Warmer and shorter winter periods will result in a decrease of seasonal snow as well as earlier and faster snow melt.  A decrease in water availably, coupled with increased demand will put strain on agricultural systems and vulnerable groups. Reduced snow thickness and duration, and higher temperatures will lead to lower river flow and decreased capacity for soil-moisture recovery. Increased water stress for agricultural areas and high temperatures may also impact river and lakes, affecting fish populations. Increased heat may lead to increased water borne diseases. The catastrophic floods experienced in recent years have led to increased investments in Romania’s flood management, prevention structures and operational interventions. The country’s river and hydro-technical networks will also be impacted by changing trends and risks of floods as well as increased aridity. 

This section provides insights into projected climate change impacts on various hydrological indicators.


Data presented under Historical Climate Conditions are reanalysis products derived from ERA5-Land data. ERA5-Land is a global land-surface dataset at 9 km resolution, consistent with atmospheric data from the ERA5 reanalysis from 1950 onward. Climate reanalyses combine past observations with models to generate consistent time series of multiple climate variables. They provide a comprehensive description of the observed climate as it has evolved during recent decades, on 3D grids at sub-daily intervals. 

This data has been collected, aggregated and processed by the Climate Resilience Cluster of the European Space Agency’s (ESA) Earth Observation for Sustainable Development (EO4SD) initiative.
