A new paper "Communities of practice. One size does not fit all" is now available online in the journal Climate Services. The paper, by Katharine Vincent, Anna Steynor, Katinka Waagsaether and Tracy Cull, furthers the argument for a nuanced understanding of communities of practice (COPs) that recognises the intradisciplinary and transdisciplinary variants. For successful climate services that enable adaptation to climate change, transdisciplinary COPs are typically required that bring together producers and users. This paper reflects on the role that donor-funded projects can play in supporting the effective generation of sustainable COPs.
