The formal space for national, sub-national and international adaptation governance emerged at COP 16  when adaptation was recognised as a similar level of priority as GHG mitigation. The Paris Agreement  built on this and the 2030 Sustainable Development Agenda  to link adaptation to development and climate justice. It also highlighted the importance of multi-level adaptation governance, including new non- state voices and climate actors that widen the scope of adaptation governance beyond formal government institutions. For example, individuals can act as agents of changes in their own behaviour, such as via change in their consumption patterns, but also generate change within organisations, fields of practice and the political landscape of governance. Accordingly, these interactions among actors across different scales implies the need for wider modes of, and arena for, engagement around adaptation to accommodate a diversity of perspectives  .
