Co-designing adaptation decision support: meeting common and differentiated needs

As exposure to climate change increases, there is a growing need for effective adaptation decision support products across public, private and community sectors and at all scales (local, regional, national, international). Numerous guidance products have been developed, but it is not clear to what extent they meet end-user needs, especially as development has been fragmented and many products lack continuing support, learning and improvement. It is timely to address the development of more intentional and coordinated support strategies that draw on the experience to date and what end-users themselves say they need. We have taken such an approach to co-design future support strategies for Australia at national and sub-national (sectoral, locational and/or jurisdictional) levels. Several supporting frameworks are introduced to assist in the clarification of common needs (e.g. incorporation of leading adaptation practices) versus differentiated needs across sectors (e.g. a ‘decision entry points’ framework) and individual organisations (e.g. a ‘decision domains’ framework). The collaborative process also identified key principles that should underpin national and sub-national support strategies and product development. A comparison with international experience indicates that the findings and principles should also be relevant to other nations, and to international and sub-national agencies developing adaptation support strategies and products.
