Title Quantifying the Influence of Circular Economy and Cli-mate Resilience on Freshwater Withdrawals Across Europe

Freshwater resources are increasingly pressured by socioeconomic development, cli-mate variability, and evolving sustainability practices. This study investigates the combined influence of economic growth, circular economy adoption, climate resili-ence, and population size on freshwater withdrawals across European countries. Using multiple linear regression analysis, we quantify how these factors jointly impact na-tional freshwater consumption. Data from Eurostat and the ND-GAIN Country Index were analyzed to assess circular material use rates, climate adaptation capacity, GDP per capita, and population effects on freshwater withdrawals. Results indicate that population size is the strongest and only statistically significant predictor of freshwa-ter withdrawals, with larger populations correlating with increased water use. Alt-hough circular economy indicators and climate resilience show expected directions of influence, positive and negative respectively, their effects were not statistically signif-icant in this model. Economic growth measured by GDP per capita also did not signif-icantly affect freshwater withdrawals. These findings highlight that demographic fac-tors remain dominant drivers of water demand in Europe, while the mitigating roles of circular economy practices and climate resilience require further investigation. The study underscores the importance of integrating population dynamics into water management policies and calls for enhanced empirical research to clarify the potential of sustainability strategies in reducing freshwater pressures.
