Du développement durable au développement des individus, des collectifs et des organisations: activité, usages et valeurs.

This paper proposes a discussion on developmental intervention mobilized within the context of Sustainable Development. Based on the description of two research-interventions - one concerns the prevention of occupational risks within the sector of household waste sorting; the other one concerns the design of a sustainable neighborhood - we discuss the values embedded in the operators (or users) activity. We argue that such values drive both the development of people, groups and organizations and the Sustainable Development (economic, environmental, social). But taking values into account involves collective debates and questions the scale of action to transform situations. We finally discuss what values-based debates imply in comparison with debates on other dimensions of activity. [ABSTRACT FROM AUTHOR]
