Grey literature on adaptation is also proliferating, typically authored by organisations funding and implementing adaptation. This literature often documents a range of adaptation strategies  and lived experiences of adaptation efforts, including helping give voice to marginalised groups, and highlighting the importance of IK and LK . However, most of the lessons learned through implementation of adaptation projects and programmes are still not captured in academic or even grey literature and thus remain less systematically analysed. Crucially, the large gaps in documentation of adaptation knowledge mean that a lack of published evidence about a given issue does not necessarily reflect its absence in real life-a qualification about adaptation research that readers of AR6 should appreciate.
