This thesis explores the role of environmental perceptions and activism in migration decision-making within the context of a country highly vulnerable to climate change. It focuses on a case study of young climate activists in Bangladesh, and their aspirations for staying or moving. The qualitative data were collected through semi-structured interviews. For analysis of migration decisions, the study utilizes a theoretical framework of aspirations and capabilities by De Haas (2021), while incorporating concepts of Hirschman’s (1978) “voice” and Robins’(2022) “duty to loyalty”. The study reveals that climate activists are aware of and concerned about environmental changes, but do not perceive them as immediate threat to their current livelihoods. While they face daily challenges and witness the vulnerability of communities, they express hope and actively choose to stay in their country. Activism serves them to voice their concern and help their community. The constant interaction between the environmental perceptions and activism, shapes their capacity to envision a better future and enhances their aspirations for staying in their motherland
