The authors recognised that the survey did not necessarily reflect the latest activity in this area due to time lags between policy development and reporting to the UNFCCC. In addition to that, national adaptation planning is likely to have progressed markedly (at least in the most active countries) over the six years since the paper’s publication. These have primarily focused on European countries but some have also included non-European OECD countries - for example, Australia and the United States (Bauer, Feichtinger and Steurer, 2011, Preston, Westaway and Yuen, 2011). The review identified several typical strengths and weaknesses in adaptation strategies - the strengths include targeted research and good planning for implementation, review and funding, while weaknesses included a lack of co-ordination between sectors and unclear allocations of responsibilities between different administrative levels. Preston, Westaway and Yuen (2011) further highlight the institutional and capacity challenges to implementation. Bauer, Feichtinger and Steurer (2011) focus particularly on co-ordination and integration in ten OECD countries, both horizontally across policy sectors and vertically across jurisdictional levels.
