Cities and other state and local entities are taking the lead in adaptation efforts, particularly in terms of mainstreaming the use of many approaches to adaptation. These approaches include a suite of efforts ranging from assessment of impacts and vulnerability , planning processes, implementation of identified strategies and evaluation of the effectiveness of these strategies. Other institutions  also are making significant progress in the adaptation arena, particularly at local to regional levels.
