National Adaptation Plans (NAPs) are central instruments supporting developing countries in their adaptation efforts and enhancing climate resilience. As the NAP documents outline a country's vulnerabilities to climate change and planned adaptation strategies, it is essential to examine how the most vulnerable groups are considered. In the IPCC’s Sixth Synthesis Report, the concepts of maladaptation and transformational adaptation feature prominently, with prior research connecting these concepts to the inclusion of vulnerable groups in adaptation efforts.This thesis provides an in-depth assessment of how vulnerable groups and communities are considered in the three selected NAPs of Bhutan, the Marshall Islands, and Zambia. A normative theoretical framework, the maladaptation-transformative adaptation continuum, is developed from relevant academic research to examine the consideration of vulnerable groups and communities throughout the NAP. Utilising a deductive qualitative content analysis, the central elements of this framework will be operationalised to review the three selected NAP documents. The findings indicate that all of the examined NAPs take vulnerable groups and communities into account by explicitly identifying the most vulnerable social groups, and including adaptation actions that target these vulnerable groups. The inclusion of vulnerable groups and communities in the formulation process and the planned implementation of adaptation measures vary, reflecting different positions along the maladaptation-transformative adaptation continuum.
