While more than 170 countries have policies that address adaptation , very few have operational frameworks to track and evaluate implementation and results . In Europe, for example, most countries have adopted a national adaptation plan or strategy, but only few are tracking whether ambitions are realised . Moreover, climate risks are interconnected across scales, regions and sectors  , complicating causal attribution. National assessments of progress usually do not assess private sector and non-governmental adaptation and barely account for climate risks that transcend across borders, for example through supply chains or shared ecosystems . In addition, adaptation action in one place or time can potentially lead to negative effects elsewhere  . Hence, determining the collective adequacy and effectiveness  of adaptation responses is different from simple aggregates of national and sub-national information .
