CONSISTENCY IN RIVER HEALTH ASSESSMENT METHODS: A PERSPECTIVE FROM THE INTERFACE BETWEEN SCIENCE AND MANAGEMENT
This paper examines how trends in the Australian water sector of shrinking interest in/budgets for national river health assessment, greater localism in water management, growing demand for diagnostic indicators of river health, and normal scientific progress, affect five factors thought by Nichols et al. (2016) to underpin nationally consistent river assessment programs. We consider when these effects are large enough to warrant a change in assessment methods, and whether such changes are likely to reduce the consistency of assessment results. It is argued that i) consistency in assessment methods should be encouraged, ii) however, over time, changes to assessment methods are unavoidable, and some changes should be encouraged even though they will reduce consistency in results through time, and iii) characterizing long-term trends in river health will therefore require an understanding of the congruence in the results of assessments based on current and new methods. We then examine whether a well-developed framework for comparing assessment results – FARWH (Framework for Assessing River and Wetland Health) – is robust to the expected changes to methods arising from the water sector trends.
