Adaptation plans refer to more substantive planning documents which establish specific policies and measures to be taken. This division is reflected in the summary table below, which groups countries into four subcategories - those which have not published an adaptation strategy, those which have not published a strategy but have taken significant national action, those which have published a strategy but not a full adaptation plan, and those which have published both a strategy and a plan. The distinction between strategies and plans is somewhat subjective - countries’ adaptation planning documents vary widely in their coverage and concreteness.
