Eliciting the Implicit Knowledge and Perceptions of On-Ground Conservation Managers of the Macquarie Marshes
(2006) Fazey, Ioan; Proust, Katrina; Newell, Barry; Johnson, Bill; Fazey, John A.
"Knowledge that has been developed through extensive experience of receiving and responding to ecological feedback is particularly valuable for informing and guiding environmental management. This paper captures the implicit understanding of seven experienced on-ground conservation managers about the conservation issues affecting the Ramsar listed Macquarie Marshes in New South Wales, Australia. Multiple interviews, a workshop, and meetings were used to elicit the manager's knowledge. The managers suggest that the Macquarie Marshes are seriously threatened by a lack of water,and immediate steps need to be taken to achieve more effective water delivery. Their knowledge and perceptions of the wider societal impediments to achieving more effective water delivery have also led the managers to suggest that there may be system feedbacks that are reinforcing the tendency for water agencies to favor the short-term interests of the irrigation industry. Although the managers clearly have certain personal interests that influence their understanding and perceptions, much of their knowledge also appears to have been heavily influenced by their ecological understanding of the wetland's dynamics. This paper highlights that although all stakeholders clearly need to be involved in making decisions about conservation and how resources should be used, such decisions should not be confused with the need for consulting people with the appropriate ecological expertise to help determine the degree to which an ecological system is threatened, the likely ecological causes of the threats, and actions that may be needed to restore and maintain a functional ecosystem."
Enhancing the Resilience of the Australian National Electricity Market: Taking a Systems Approach in Policy Development
(2011) Newell, Barry; Marsh, Debborah M.; Sharma, Deepak
"As the complexity and interconnectedness of present-day social-ecological systems become steadily more apparent, there is increasing pressure on governments, policy makers, and managers to take a systems approach to the challenges facing humanity. However, how can this be done in the face of system complexity and uncertainties? In this paper we briefly discuss practical ways that policy makers can take up the systems challenge. We focus on resilience thinking, and the use of influence diagrams, causal-loop diagrams, and system archetypes. As a case study, set in the context of the climate-energy-water nexus, we use some of these system concepts and tools to carry out an initial exploration of factors that can affect the resilience of the Australian National Electricity Market. We stress the need for the electricity sector to prepare for the impacts of global change by encouraging innovation and diversity, supporting modularity and redundancy, and embracing the need for a policy making approach that takes account of the dynamics of the wider social-ecological system. Finally, taking a longer term view, we conclude by recommending that policy makers work to reduce reliance on conventional market mechanisms, institute continuing cross-sector dialogue, and promote basic education in system dynamics."
