It is thought that a dichotomy exists between two apparently contradictory belief systems: the so-called "Human Exception Paradigm" (HEP)--an anthropocentric belief system--and the "New Environmental Paradigm" (NEP), of ecocentric nature. The aim of this article was to test the presence of an integrative, nondichotomic, New Human Interdependence Paradigm (NHIP) and its influence on water conservation practices. The NHIP envisages interdependence between human progress and nature conservation and conceives it as a dynamic process of integration and incorporation of human needs into natural processes. Seven hundred and fifty-nine individuals living in cities of France, Italy, Mexico, and India responded to items of a purposively developed measuring instrument (the NHIP scale), as well to items of the HEP-NEP scale. They also self-reported the frequency of water conservation actions at their households. The NHIP coherently emerged from its observed indicators and it was a slightly better predictor of water conservation than the HEP-NEP scale.
