Scientists from a wide range of disciplines, all now associated with the International Ecotechnology Research Centre at Cranfield University in England, say that uncertainty should be the starting point of diagnosing and managing environmental change, rather than the traditional approach of reducing complexity into simple relationships that are easy to manipulate. They introduce a number of techniques from social science, agricultural and environmental studies, systems thinking, and modelling that they have drawn together into an integrative method. They apply it to an ongoing case study in the Peleponnese region of Greece. The intended audience is wide, so the background necessary to understand the techniques described are included.
