Adaptation is context-specific by nature (AC, 2015) and adaptation responses need to be tailored to a country’s geography and socio-economic, political, as well as ecological systems. National approaches to adaptation, as well as to monitoring and evaluating adaptation reflect this and vary considerably between countries, which would make them very difficult to aggregate.19. Indeed, the Adaptation Committee (2015) also indicates that it would “not be useful” for all countries to use the same set of adaptation indicators.
