The design of adaptation strategies that promote urban health and well-being in the face of climate change requires an understanding of the feedback interactions that take place between the dynamical state of a city, the health of its people, and the state of the planet. Complexity, contingency and uncertainty combine to impede the growth of such systemic understandings. In this paper we suggest that the collaborative development of conceptual models can help a group to identify potential leverage points for effective adaptation. We describe a three-step procedure that leads from the development of a high-level system template, through the selection of a problem space that contains one or more of the group’s adaptive challenges, to a specific conceptual model of a sub-system of importance to the group. This procedure is illustrated by a case study of urban dwellers’ maladaptive dependence on private motor vehicles. We conclude that a system dynamics approach, revolving around the collaborative construction of a set of conceptual models, can help communities to improve their adaptive capacity, and so better meet the challenge of maintaining, and even improving, urban health in the face of climate change.
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.
Rapid, human‐induced global change presents major challenges to researchers, policy‐makers and land managers. Addressing these challenges requires an appreciation of the dynamics of ecological systems. Here, we propose ‘landscape fluidity’ as a perspective and research agenda from which to consider landscapes in the process of changing rapidly through both time and space. We define landscape fluidity as the ebb and flow of different organisms within a landscape through time. A range of existing ideas, themes and practical approaches are relevant to landscape fluidity, and we use a case study of scattered tree landscapes in south‐eastern Australia to illustrate the benefits of a landscape fluidity perspective. We suggest that a focus on landscape fluidity can bring a renewed emphasis on change in landscapes and so help unify a range of currently separate research themes in biogeography, ecology, palaeoecology and conservation biology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
