22 pages., via online journal., Identifying and communicating uncertainty is core to effective environmental
assessment (EA). This study evaluates the extent to which uncertainties are considered
and addressed in Canadian EA practice. We reviewed the environmental protection
plans, follow-up programs, and panel reports (where applicable) of 12 EAs between
1995 and 2012. The types of uncertainties and levels of disclosure varied greatly.
When uncertainties were acknowledged, practitioners adopted five different
approaches to address them. However, uncertainties were never discussed or
addressed in depth. We found a lack of suitable terminology and consistency in how
uncertainties are disclosed, reflecting the need for explicit guidance, and we present
recommendations for improvement. Canadian Environmental Impact Statements are
not as transparent with respect to uncertainties as they should be, and uncertainties in
EA need to be better considered and communicated.
8 pages., via online journal., Formalised methods to address uncertainty are becoming the norm in hydrological modelling, yet they remain fragmented and highly academic, thus limiting their utility for practitioners. Using a qualitative, empirical study of the PIREN-Seine program in France, this paper explores the proccesses behind this trend in an effort to elucidate its prevalence despite inherent limitations when applied to a decision-making context. We identify: 1/ displacement of ‘uncomfortable knowledge’, 2/ fragmented responsibility, 3/ confidence, and 4/ relational framing as interconnected factors, which concurrently support the production of scientific knowledge and the social construction of ignorance, whether it be wilful or intentional. We posit that ignorance is implicitly negotiated among researchers and practitioners in order to reconcile cognitive dissonance and maintain confidence, thereby allowing water managers to take action in the face of uncertainty. Finally, we put forth the notion that having our ‘eyes wide shut’ can be interpreted in two ways: one facilitates the normalisation of ignorance, leaving us vulnerable to unexpected surprises; the other promotes transparent and explicit communication in support of more adaptive and robust decisions.
