This article suggests how adaptation can be addressed at different levels and w ithin various international regimes. For that purpose, adaptation is discussed through the lenses of three major discourses: development, resilience and transition theory. We define adaptation as the adjustment of ecological and socio-econom ic systems to current or projected climate changes (Verheyen, 2002). Following the IPCC (IPCC, 2007b) we define vulnerability to clim ate change as the degree to which natural and social systems are susceptible to, and unable to cope with, adverse impacts. We define discourse as a system of thoughts composed of ideas, beliefs, attitudes, actions and practices (Lessa, 2006).
