The concepts of enablers, catalysts and the solution space help AR6 assess ways to speed the implementation and expand the range of adaptation solutions. Many potential solutions have not yet been implemented, despite the gap between current and adequate levels of adaptation. Enablers enhance the feasibility of adaptation options and include governance, finance and knowledge. Catalysts accelerate and motivate the adaptation decision making process. The concept of solution space-defined as the space within which opportunities and constraints determine why, how, when and who adapts to climate risks-helps this in assessing how human choices and exogenous changes can expand and contract the set of effective, feasible and just solutions.
