Exploring the scope of public and private responsibilities for climate adaptation

Abstract

Although in practice the division of responsibilities in adaptation to climate change is often not explicitly decided upon, governments appear to be primary actors in adaptation planning. However, literature suggests that the governance of adaptation requires roles for both public and private actors so that responsibilities can be shared and all of society's resources can be fully exploited. Active involvement of all societal actors might overcome problems of inefficiency and raise the legitimacy of adaptation action. This article presents a framework that enables the characterization and explanation of existing governance arrangements in terms of responsibility divisions among public and/or private actors, and that facilitates the search for alternative responsibility divisions and their associated advantages and disadvantages. The framework is illustrated with an example of a governance arrangement for green roofs as an adaptation measure for storm water retention in Rotterdam, the Netherlands. The merit of the framework is that it promotes the conscious deliberation of considerations in the public-private divide, taking into account some specific challenges to the governance of climate adaptation. It may, therefore, support well-informed decisions on responsibility divisions in climate adaptation by local governments.
