Managing threats to floodplain biodiversity and cultural values on Kakadu National Park.Part I: Risks from sea level rise due to climate changePart II: Participatory methods and integrated assessmentsFinal report to the Northern Hub of the National Environmental Research Program (NERP).

[摘要] Executive summary (Parts III)1. Kakadu National Park is a World Heritage icon famous for its natural and cultural values, particularly its coastal floodplains that encompass Ramsar‐listed freshwater wetlands. These floodplains are highly vulnerable to climate change induced sea level rise (SLR) because they are low‐lying, a risk that will exacerbate with increases in extreme weather events such as storm surges and flooding.2. The overall aim of this component of the NERP Floodplains study is to contribute new knowledge to support the management of risks to natural and cultural values from future saltwater intrusion due to climate change induced sea level rise.3. Part I of this report assesses the potential biodiversity impacts of three future climate change‐SLR scenarios (2030 0.14m; 2070 0.70m;2100 1.1m) on a selection of key plant and animal indicator species, in particular the iconic Magpie Goose and their seasonal habitats. These species are important bush tucker for local Indigenous people and so have high cultural value.4. Part II of this report undertakes an integrated assessment of socio‐ecological and cultural aspects of potential sea level rise impacts, and draws on the outcomes of a series of participatory workshops and interviews with both Traditional Owners and Parks staff to elicit floodplain values and management options such as adaptation responses. Yellow Water is used as a case study because its location beyond the tidal reach in the South Alligator River systemsuggests that its wetlands will likely be the main freshwater refuge from the future effects of saltwater inundation, as confirmed in Part I of this study.
