The thesis aims to examine the approaches of humanitarian organizations towards achieving gender transformative changes and the challenges as well as obstacles to implementing gender transformative programming in the ongoing humanitarian response in Bangladesh for the Rohingyas since 2017. The research is conducted through applying qualitative methodology, consisting of document analysis and interviews. The document analysis is based on annual reports and gender analysis of humanitarian organizations working in the Rohingya response. Eight interviews conducted for this thesis provide insights and reflection from gender practitioners who are implementing gender transformative programs. The gender transformative approach focuses on removing the barriers, so women and men can achieve full access to resources and opportunities promoting gender equality and a gender transformative program that adopts the approach from the development till the results stage. The gender integration continuum tool and Gender and Age Marker (GAM) help gender practitioners evaluate and shape their programs with a transformative approach. The transformative programs are crucial for the response considering the existing gender gaps and needs, and for the humanitarian organizations to recognize the need for and importance of gender transformative programs. The barriers and challenges of implementing a gender transformative program in the Rohingya crisis are mainly three types: a) legal, b) structural, and c) cultural challenges. The lack of refugee rights of the Rohingyas results in establishing a response mechanism that is based on practical needs rather than strategic needs. It also hinders the implementation of the GBV case management program. There are structural challenges arising from the lack of capacity among the staff members, limited allocation of time from unequal practices, and lack of gender mainstreaming in humanitarian organizations. Culturally, the tendency to follow universal transformative program models and the reluctance of the humanitarian community to invest in gender transformative programs creates challenges in implementing gender transformative programs.
