A new comment "Addressing power imbalances in co-production" has just been published in Nature Climate Change. The comment, led by Katharine Vincent with Suzanne Carter, Anna Steynor, Emma Visman and Katinka Lund Waagsaether, reflects on investigations into co-production in the Future Climate For Africa and WISER programmes. Co-production is an increasingly popular approach to knowledge generation encouraged by donors and research funders. However, power dynamics between institutions in the global North and South can, if not adequately managed, impede the effectiveness of co-production and pose risks for long-term sustainability.
