Le développement soutenable: un sujet controverse chez les économistes

SUMMARY The objective of sustainable development is translated in very different ways. We propose a panorama of economic proposals related to sustainability. This one is setting on three groups of theoretical works: the first one, which is the point of view of mainstream economics, brings forward the idea of sustainable growth as a necessary and sufficient condition to have a sustainable development; the second, more conscious of physical limits, try to elaborate socio-environmental constraints, inside of which economic development must go on; the third one, influenced by third world experiences, insists on social inequalities and question the sense of the notion of development. Key-words: economics; sustainable development; sustaining growth; decrease.
