Adaptation to changing and new environmental conditions is of fundamental importance to sustainability and requires concerted efforts amongst science, policy, and practice to produce solutionoriented knowledge. Joint knowledge production or coproduction of knowledge have become increasingly popular terms to describe the process of scientists, policy makers and actors from the civil society coming together to cooperate in the production, dissemination, and application of knowledge to solve wicked problems such as climate change. Networks are particularly suited to produce knowledge in a joint fashion. However, the process of joint knowledge production (JKP) in networks has rarely been examined. In this paper, we present a sketch of the adaptation network landscape and assess how joint knowledge production supports the development of solutionoriented knowledge in climate change adaptation networks. We conclude that the processes of JKP are diverse, complex, and highly dependent on the interests and roles of actors within the network. To keep such processes alive, signposts in form of analysis and intermediary products along the network lifetime should be positioned as means of stocktaking and monitoring for the future.
