Cause-effect pathways in mangrove ecosystems; can they make management easier?
Paling, E. and Pedretti, Y (2011) Cause-effect pathways in mangrove ecosystems; can they make management easier? In: 48th Annual Conference of the Australian Marine Science Association, 3 - 7 July, Fremantle, Western Australia.
Conventional regulation relies on the modelling of physical systems to connect changes in human activity to the metric of system performance. Management of complex natural systems also requires models that link patterns of human impact to changes in the relevant metric of system performance. Unfortunately however, the determination of all but the most simple cause and effect pathways regarding biological systems, including mangroves, remains largely incomplete. Present research outcomes now allow us to gain some idea of the pathways often associated with mangrove habitat degradation or loss. Conceptual modelling illustrates that, while a number of natural factors affect mangroves, anthropogenic impacts can be fairly easily defined. This allows us to focus our attention when considering activities that may impact upon these ecosystems. This paper will describe cause/effect pathways applicable to all mangrove systems and the impacts associated with them.
