"This paper explores the relationship between environmental worldviews and. So far, two apparently opposed belief systems have been proposed as worldviews guiding environmental behaviour. On the one hand, a system focusing on human needs and its prevalence as species, which disregards the intrinsic value of the natural world, on the other hand, an ecocentric worldview that conceives humans just as one more component of Nature, and claims for a control of human activities in order to avoid a disruption of Earth's ecosystems. Most authors in Conservation Psychology consider that a dichotomy exists between these apparently contradictory belief systems, although others have not found a contradiction. The aim of this paper is to test the presence of an integrative Eco-Anthropocentric Paradigm (EAP), which conceives Nature as a source of resources for satisfying human needs while, at the same time, sees it as having intrinsic value and being in need of preservation. A special objective of this research was to investigate the influence that this holistic belief system has on water conservation, considered to be a critical sustainable behaviour. 500 individuals living in cities of France, Italy, Mexico and India responded to items of a recently developed questionnaire (the EAP), as well to items of the well known "New Environmental Paradigm" scale. They also self-reported the frequency of water conservation actions at their households. Results were contrasted between national groups in order to see whether the EAP is more developed in collectivistic (Mexico, India) or in individualistic (France, Italy) countries. These results are discussed in terms of the value of sustainable belief systems and their relationship with conservation behaviour. "
