The potential for transferring and translating existing adaptation to climate change decision-support tools for use in different settings provides both opportunities and challenges to those wanting to support such decisions in or for the targeted community/organisation. The opportunities are related to being able to build on an existing credible and tested tool and its supportive resources and foregoing the costs associated with developing such themselves. The challenges relate to taking advantages of the strengths of an existing tool whilst adapting it and its supportive resources such that they are fit for purpose and accepted within the targeted community/organisation. This paper identifies and explores these opportunities and challenges through those revealed as a result of transferring and translating the UKCIP Adaptation Wizard for use within other parts of the world and in different communities and organisations. Whilst drawing on a number of different examples of where the Wizard has been translated, this paper particularly focuses on the transfer and translation for use in Portugal and in Brazil. General lessons learnt related to transferring adaptation decision-support tools are identified and used to develop a practical framework. The intention is to provide insights that have broader implications for those considering transferring similar adaptation decision-support tools, but also for tool developers who want to see their tools being used more broadly.
