Source: (2000) In Mediation in Context, ed. Marian Liebmann, 211-224. With an introduction by Marian Liebmann. London: Jessica Kingsley Publishers.While environmental decision making contains classic ingredients of conflict, the main approach for decision making has been a rational scientific approach, thus neglecting the human dimension. Conflict over environmental decision making is often exacerbated, not resolved. The authors explore mediation as an alternative to such conflict. Their discussion covers basic concepts of consensus building, conditions for consensus, and practices or techniques for consensus building. Sidaway and Ingram illustrate their perspectives with case examples of environmental decision making and lessons to be learned from them.
