National Adaptation Plans  submitted to the UNFCCC have been reviewed for quality by Woodruff and Regan . In their review, Woodruff and Regan used a number of indicators grouped within established 'quality principles'. They found that the plans were more oriented at the strategic level or at the level of specific projects rather than identifying methods for resolving cross-sectoral or cross-jurisdictional interactions or issues . A key recommendation from their review and supported by other studies  is that plans would be improved greatly by having inputs from multiple government agencies and multiple sectors , which could provide the basis for planning and review of integrated adaptation. Also, the plans need greater attention to implementation , and the identification of metrics by which success  and performance can be measured , a common issue for adaptation planning generally .
