Ecological economics, 63(4), 664-675.https://hdl.handle.net/1805/3589Ecological Economics has developed as a “transdisciplinary science,” but it has not taken significant steps toward a truly integrated process of evaluating anthropogenic ecological change. The emerging dominance within ecological economics of the movement to monetize “ecological services,” when combined with the already well-entrenched dominance of contingent pricing as a means to evaluate impacts on amenities, has created a “monistic” approach to valuation studies. It is argued that this monistic approach to evaluating anthropogenic impacts is inconsistent with a sophisticated conception of ecology as a complex science that rests on shifting metaphors. An alternative, pluralistic and iterative approach to valuation of anthropogenic ecological change is proposed.en-USecological economicsvaluation studiesArticle
