Some elements may be missed because the NCs are intended to provide an overview of the main activities underway, rather than an exhaustive account of all the adaptation activities taking place within a country. Additionally, the majority of NCs included in the analysis were published in 2009 or 2010, and due to the pace of change in adaptation programmes they may lack some important recent developments. The review of NCs has, therefore, been complemented by information from national planning documents, direct contact with member governments and the May 2012 Policy Forum on Adaptation to Climate Change in OECD Countries.
