Abstract
This study investigates the determinants of water conservation behaviour through a comprehensive empirical analysis and explores spatial heterogeneity in their coefficients at a regional unit scale, with a specific focus on Italy. The results of the ordinal logistic regression indicate that various socio-demographic, infrastructural, behavioural, and social factors, including trust in public institutions, trust in people, and charitable donations, have a significant impact on water conservation. Furthermore, the study reveals statistically significant spatial variations in the relationship between water conservation and its five factors, including education, energy saving, and trust in public institutions, using geographically weighted regression.
