Global assessments may have the objective to compare adaptation over time and across sectors and regions . Such comparison requires a consistent definition of concepts  and the identification of variables that are both generic enough to be applicable from one context to another and specific enough to illustrate national circumstances. To date, finding such balance has proven to be challenging . The context dependence of adaptation outcomes poses limits for meaningful comparisons. Even people exposed to the same climate hazard may be differentially affected due to varying levels of vulnerability and resilience , meaning that perceptions on adaptation outcomes can also differ .
