Millennium Ecosystem Assessment Northern Australia floodplain and coastal wetlands Max Finlayson National Centre for Tropical Wetland Research Darwin, NT Northern Australia floodplain and coastal wetlands Aim Participation Geographic Region / Location Data sources / Scale Components Next steps Aim Provide information on the floodplain and coastal ecosystems and their services at multiple scales and taking into account multiple pressures Geographic Region / Location Northern Australia – east of Darwin Coastal biogeographic region Alligator Rivers – 28 000 km2 Catchments of three rivers Kakadu National Park – World Heritage & Ramsar listed Geographic Region / Location Participation Discussed through existing panels, boards • • • • • Biophysical scientists Social scientists Management agencies Local community / indigenous Private sector Data sources • Information derived from current or planned projects • Biophysical features – extensive; ready access • Social/cultural features – extensive; discuss access • Floodplain services – variable; derived from biophysical data and managers • Pressures – extensive analyses; risk assessments underway Scale • Biogeographical or catchment scale 1:100 000 to 1:250 000 • Catchment scales 1:50 000 to 1:100 000 • Habitats / river reaches 1:10 000 Components • • • Inventory/mapping – GIS multiple scale Floodplain services – indigenous, biodiversity, tourism, recreation (fish stocks, mitigation of climate change, cattle grazing) Risk assessment of major pressures – invasive species, water pollution, infrastructure, burning, climate change Hierarchical approach to wetland inventory Level 1 Scale (nominal) 1:1 000 000 Geology; climate; landcover River basin or island Level 2 1:250 000 Location; altitude; area; land systems; climate; hydrology; vegetation Wetland region Level 3 Wetland complex 1:50 000 Location; physico-chemical and biological features; classification; jurisdiction; ecosystem services Level 4 Location; physico-chemical and biological features (ecological character); land tenure; land use; management issues and threats... Basic (“Core”) dataset stored in Database with GIS Interface Wetland habitat 10 The Risk Assessment Framework (modified from van Dam et al. 1999; Ramsar 2000) Identification of the problem (eg site assessment: sitespecific information on stressor & environment) Analysis Identification of the effects (field assessment: eg bioassays, monitoring, surveys etc.) Identification of the extent of the problem (eg chemical concs,spatial & temporal distribution) Identification of the risk (comparison of effects with the extent using a GIS framework) Risk management/ Risk reduction (manage inputs/ alter practices) Monitoring (use of early warning and rapid assessment indicators/ GIS-based approach) Major pressures Major pressures – insidious effects of climate change Next steps Further consultation – with participants, advisors and stakeholders Collation / analysis – based on previous and current projects Communication – discussing and finalising analyses and outcomes Thank you
